No. 14/503,078, filed Sep. 30, 2014, which claims priority to U.S. Provisional Application Ser. No. 62/006,029, filed May 30, 2014, all of which are incorporated herein in their entireties. 
    
    
     BACKGROUND 
     1. Field 
     The present disclosure relates generally to computer user interfaces for battery-powered devices, and more specifically to a user interface for tracking battery usage by software application. 
     2. Description of Art 
     In recent years, portable electronic devices such as cellular phones, tablet computers, and laptop computers have increasingly become multifunctional devices, largely driven by their ability to support a wide range of software applications. Moreover, such devices typically rely on rechargeable batteries to power the hardware and software systems that support the operation of such applications. As these devices become more fundamentally integrated into the daily routine of users, tracking of battery usage to better understand battery-consumption and optimize device use times has become increasingly important. 
     BRIEF SUMMARY 
     While these devices may provide interfaces for monitoring overall remaining battery life and, in some cases, for monitoring additional details such as time-of-use since the battery was last charged, such limited interfaces would not provide a user with the ability to track battery usage in relation to particularly software applications—and therefore the particular functions—that are being used on the device. Such interfaces also cannot provide recommendations for further conserving battery power based on patterns of device usage, particularly from an application-based perspective. 
     Accordingly, there is a need for additional tracking information with respect to battery usage on their device, such as information relating battery usage more directly to the functions that the user may employ most. The devices, methods, and interfaces described herein address the issues described above and reduce the cognitive burden on a user, produce a more efficient human-machine interface. 
     In some embodiments, a method of attributing and displaying battery usage comprises: at an electronic device with one or more processors and memory: attributing a portion of battery usage of a first hardware subsystem to a first application based on the battery usage of the first hardware subsystem that occurred during activity by the first application; attributing a portion of the battery usage of the first hardware subsystem to a second application based on the battery usage of the first hardware subsystem that occurred during activity by the second application, receiving a request to display a battery usage user interface, and in response to the request, displaying the battery usage user interface that includes a representation of the battery usage attributed to the first application and a representation of the battery usage attributed the second application. 
     In some embodiments, a method of determining exceptional battery usage comprises: at an electronic device with one or more processors and memory: determining battery usage attributed to a first application over a first time period, wherein the battery usage attributed to the first application over the first time period includes exceptional battery usage that occurred during the first time period; receiving a request to display a battery usage user interface; and in response to receiving the request: in accordance with a determination that the exceptional battery usage attributed to the first application that occurred during the first time period meets qualifier display criteria, displaying a representation of battery usage attributed to the first application over the first time period that includes qualifier information that is indicative of one or more causes of the exceptional battery usage attributed to the first application over the first time period; and in accordance with a determination that the exceptional battery usage attributed to the first application that occurred during the first time period does not meet the qualifier display criteria, displaying a representation of battery usage attributed to the first application over the first time period that does not include the qualifier information. 
     In some embodiments, a method of displaying a battery usage interface comprises: at an electronic device with one or more processors and memory: receiving a request to display a battery usage user interface; determining whether battery savings suggestion criteria have been met for a first setting; and in response to the request: in accordance with a determination that the battery savings suggestion criteria have been met for the first setting, displaying a battery usage interface that includes a suggestion for adjusting the first setting; and in accordance with a determination that the battery savings suggestion criteria have not been met for the first setting, displaying a battery usage interface that does not include the suggestion for adjusting the first setting.

     DETAILED DESCRIPTION 
     In the following description of the disclosure and embodiments, reference is made to the accompanying drawings in which it is shown by way of illustration specific embodiments that can be practiced. It is to be understood that other embodiments and examples can be practiced and changes can be made without departing from the scope of the disclosure. 
     As discussed above, tracking of battery usage to better understand battery-consumption and optimize device use times has become increasingly important. It is desirable to provide an improved interface for tracking of battery usage, such as usage attributable to specific hardware and/or software subsystems, thereby allowing a user to quickly and efficiently monitor and conserve power and increase the time between battery charges. 
     Below,  FIGS. 1A-1B, 2, 3, 4A-4B, and 5A-5B  provide a description of exemplary devices for performing the techniques for tracking of battery usage.  FIGS. 5A-7  illustrate exemplary user interfaces for tracking of battery usage. The user interfaces in the figures are also used to illustrate the processes described below, including the processes in  FIGS. 8-10 . 
     Although the following description uses terms “first,” “second,” etc. to describe various elements, these elements should not be limited by the terms. These terms are only used to distinguish one element from another. For example, a first touch could be termed a second touch, and, similarly, a second touch could be termed a first touch, without departing from the scope of the various described embodiments. The first touch and the second touch are both touches, but they are not the same touch. 
     The terminology used in the description of the various described embodiments herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description of the various described embodiments and the appended claims, the singular forms “a”, “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     The term “if” may be construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” may be construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context. 
     Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Exemplary embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif. Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch screen displays and/or touchpads), are, optionally, used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch screen display and/or a touchpad). 
     In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device optionally includes one or more other physical user-interface devices, such as a physical keyboard, a mouse, and/or a joystick. 
     The device may support a variety of applications, such as one or more of the following: a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application. 
     The various applications that are executed on the device optionally use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device are, optionally, adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device optionally supports the variety of applications with user interfaces that are intuitive and transparent to the user. 
     Attention is now directed toward embodiments of portable devices with touch-sensitive displays.  FIG. 1A  is a block diagram illustrating portable multifunction device  100  with touch-sensitive display system  112  in accordance with some embodiments. Touch-sensitive display  112  is sometimes called a “touch screen” for convenience and is sometimes known as or called a “touch-sensitive display system.” Device  100  includes memory  102  (which optionally includes one or more computer-readable storage mediums), memory controller  122 , one or more processing units (CPUs)  120 , peripherals interface  118 , RF circuitry  108 , audio circuitry  110 , speaker  111 , microphone  113 , input/output (I/O) subsystem  106 , other input control devices  116 , and external port  124 . Device  100  optionally includes one or more optical sensors  164 . Device  100  optionally includes one or more contact intensity sensors  165  for detecting intensity of contacts on device  100  (e.g., a touch-sensitive surface such as touch-sensitive display system  112  of device  100 ). Device  100  optionally includes one or more tactile output generators  167  for generating tactile outputs on device  100  (e.g., generating tactile outputs on a touch-sensitive surface such as touch-sensitive display system  112  of device  100  or touchpad  355  of device  300 ). These components optionally communicate over one or more communication buses or signal lines  103 . 
     As used in the specification and claims, the term “intensity” of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact) on the touch-sensitive surface, or to a substitute (proxy) for the force or pressure of a contact on the touch-sensitive surface. The intensity of a contact has a range of values that includes at least four distinct values and more typically includes hundreds of distinct values (e.g., at least 256). Intensity of a contact is, optionally, determined (or measured) using various approaches and various sensors or combinations of sensors. For example, one or more force sensors underneath or adjacent to the touch-sensitive surface are, optionally, used to measure force at various points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., a weighted average) to determine an estimated force of a contact. Similarly, a pressure-sensitive tip of a stylus is, optionally, used to determine a pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and/or changes thereto, the capacitance of the touch-sensitive surface proximate to the contact and/or changes thereto, and/or the resistance of the touch-sensitive surface proximate to the contact and/or changes thereto are, optionally, used as a substitute for the force or pressure of the contact on the touch-sensitive surface. In some implementations, the substitute measurements for contact force or pressure are used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the substitute measurements). In some implementations, the substitute measurements for contact force or pressure are converted to an estimated force or pressure, and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure). Using the intensity of a contact as an attribute of a user input allows for user access to additional device functionality that may otherwise not be accessible by the user on a reduced-size device with limited real estate for displaying affordances (e.g., on a touch-sensitive display) and/or receiving user input (e.g., via a touch-sensitive display, a touch-sensitive surface, or a physical/mechanical control such as a knob or a button). 
     As used in the specification and claims, the term “tactile output” refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user&#39;s sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user&#39;s hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a “down click” or “up click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as an “down click” or “up click” even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user&#39;s movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as “roughness” of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an “up click,” a “down click,” “roughness”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user.

Touch screen  112  is used to implement virtual or soft buttons and one or more soft keyboards. 
     Touch-sensitive display  112  provides an input interface and an output interface between the device and a user. Display controller  156  receives and/or sends electrical signals from/to touch screen  112 . Touch screen  112  displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects. 
     Touch screen  112  has a touch-sensitive surface, sensor, or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen  112  and display controller  156  (along with any associated modules and/or sets of instructions in memory  102 ) detect contact (and any movement or breaking of the contact) on touch screen  112  and convert the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages, or images) that are displayed on touch screen  112 . In an exemplary embodiment, a point of contact between touch screen  112  and the user corresponds to a finger of the user. 
     Touch screen  112  may use LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies may be used in other embodiments. Touch screen  112  and display controller  156  may detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen  112 .

     A touch-sensitive display in some embodiments of touch screen  112  may be analogous to the multi-touch sensitive touchpads described in the following U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference in its entirety. However, touch screen  112  displays visual output from device  100 , whereas touch-sensitive touchpads do not provide visual output. 
     A touch-sensitive display in some embodiments of touch screen  112  may be as described in the following applications: (1) U.S. patent application Ser. No. 11/381,313, “Multipoint Touch Surface Controller,” filed May 2, 2006; (2) U.S. patent application Ser. No. 10/840,862, “Multipoint Touchscreen,” filed May 6, 2004; (3) U.S. patent application Ser. No. 10/903,964, “Gestures For Touch Sensitive Input Devices,” filed Jul. 30, 2004; (4) U.S. patent application Ser. No. 11/048,264, “Gestures For Touch Sensitive Input Devices,” filed Jan. 31, 2005; (5) U.S. patent application Ser.

No. 11/228,758, “Virtual Input Device Placement On A Touch Screen User Interface,” filed Sep. 16, 2005; (7) U.S. patent application Ser. No. 11/228,700, “Operation Of A Computer With A Touch Screen Interface,” filed Sep. 16, 2005; (8) U.S. patent application Ser. No. 11/228,737, “Activating Virtual Keys Of A Touch-Screen Virtual Keyboard,” filed Sep. 16, 2005; and (9) U.S. patent application Ser. No. 11/367,749, “Multi-Functional Hand-Held Device,” filed Mar. 3, 2006. All of these applications are incorporated by reference herein in their entirety. 
     Touch screen  112  may have a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user may make contact with touch screen  112  using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user. 
     In some embodiments, in addition to the touch screen, device  100  may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from touch screen  112  or an extension of the touch-sensitive surface formed by the touch screen. 
     Device  100  also includes power system  162  for powering the various components. Power system  162  may include a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices. 
     Device  100  may also include one or more optical sensors  164 .  FIG. 1A  shows an optical sensor coupled to optical sensor controller  158  in I/O subsystem  106 . Optical sensor  164  may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor  164  receives light from the environment, projected through one or more lenses, and converts the light to data representing an image. In conjunction with imaging module  143  (also called a camera module), optical sensor  164  may capture still images or video. In some embodiments, an optical sensor is located on the back of device  100 , opposite touch screen display  112  on the front of the device so that the touch screen display may be used as a viewfinder for still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user&#39;s image may be obtained for video conferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of optical sensor  164  can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor  164  may be used along with the touch screen display for both video conferencing and still and/or video image acquisition. 
     Device  100  optionally also includes one or more contact intensity sensors  165 .  FIG. 1A  shows a contact intensity sensor coupled to intensity sensor controller  159  in I/O subsystem  106 . Contact intensity sensor  165  optionally includes one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a touch-sensitive surface). Contact intensity sensor  165  receives contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ). In some embodiments, at least one contact intensity sensor is located on the back of device  100 , opposite touch screen display  112 , which is located on the front of device  100 . 
     Device  100  may also include one or more proximity sensors  166 .  FIG. 1A  shows proximity sensor  166  coupled to peripherals interface  118 . Alternately, proximity sensor  166  may be coupled to input controller  160  in I/O subsystem  106 . Proximity sensor  166  may perform as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device”; Ser. No. 11/240,788, “Proximity Detector In Handheld Device”; Ser. No. 11/620,702, “Using Ambient Light Sensor To Augment Proximity Sensor Output”; Ser. No. 11/586,862, “Automated Response To And Sensing Of User Activity In Portable Devices”; and Ser. No. 11/638,251, “Methods And Systems For Automatic Configuration Of Peripherals,” which are hereby incorporated by reference in their entirety. In some embodiments, the proximity sensor turns off and disables touch screen  112  when the multifunction device is placed near the user&#39;s ear (e.g., when the user is making a phone call). 
     Device  100  optionally also includes one or more tactile output generators  167 .  FIG. 1A  shows a tactile output generator coupled to haptic feedback controller  161  in I/O subsystem  106 . Tactile output generator  167  optionally includes one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Contact intensity sensor  165  receives tactile feedback generation instructions from haptic feedback module  133  and generates tactile outputs on device  100  that are capable of being sensed by a user of device  100 . In some embodiments, at least one tactile output generator is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ) and, optionally, generates a tactile output by moving the touch-sensitive surface vertically (e.g., in/out of a surface of device  100 ) or laterally (e.g., back and forth in the same plane as a surface of device  100 ). In some embodiments, at least one tactile output generator sensor is located on the back of device  100 , opposite touch screen display  112 , which is located on the front of device  100 . 
     Device  100  may also include one or more accelerometers  168 .  FIG. 1A  shows accelerometer  168  coupled to peripherals interface  118 . Alternately, accelerometer  168  may be coupled to an input controller  160  in I/O subsystem  106 . Accelerometer  168  may perform as described in U.S. Patent Publication No. 20050190059, “Acceleration-based Theft Detection System for Portable Electronic Devices,” and U.S. Patent Publication No. 20060017692, “Methods And Apparatuses For Operating A Portable Device Based On An Accelerometer,” both of which are incorporated by reference herein in their entirety. In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device  100  optionally includes, in addition to accelerometer(s)  168 , a magnetometer (not shown) and a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device  100 . 
     In some embodiments, the software components stored in memory  102  include operating system  126 , communication module (or set of instructions)  128 , contact/motion module (or set of instructions)  130 , graphics module (or set of instructions)  132 , text input module (or set of instructions)  134 , Global Positioning System (GPS) module (or set of instructions)  135 , and applications (or sets of instructions)  136 . Furthermore, in some embodiments, memory  102  ( FIG. 1A ) or  370  ( FIG. 3 ) stores device/global internal state  157 , as shown in  FIGS. 1A and 3 . Device/global internal state  157  includes one or more of: active application state, indicating which applications, if any, are currently active: display state, indicating what applications, views or other information occupy various regions of touch screen display  112 ; sensor state, including information obtained from the device&#39;s various sensors and input control devices  116 ; and location information concerning the device&#39;s location and/or attitude. 
     Operating system  126  (e.g., Darwin, RTXC, LINUX, UNIX, OS X, iOS, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components. 
     Communication module  128  facilitates communication with other devices over one or more external ports  124  and also includes various software components for handling data received by RF circuitry  108  and/or external port  124 . External port  124  (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with, the 30-pin connector used on iPod® (trademark of Apple Inc.) devices. 
     Contact/motion module  130  optionally detects contact with touch screen  112  (in conjunction with display controller  156 ) and other touch-sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module  130  includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module  130  receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module  130  and display controller  156  detect contact on a touchpad. 
     In some embodiments, contact/motion module  130  uses a set of one or more intensity thresholds to determine whether an operation has been performed by a user (e.g., to determine whether a user has “clicked” on an icon). In some embodiments, at least a subset of the intensity thresholds are determined in accordance with software parameters (e.g., the intensity thresholds are not determined by the activation thresholds of particular physical actuators and can be adjusted without changing the physical hardware of device  100 ). For example, a mouse “click” threshold of a trackpad or touch screen display can be set to any of a large range of predefined threshold values without changing the trackpad or touch screen display hardware. Additionally, in some implementations, a user of the device is provided with software settings for adjusting one or more of the set of intensity thresholds (e.g., by adjusting individual intensity thresholds and/or by adjusting a plurality of intensity thresholds at once with a system-level click “intensity” parameter). 
     Contact/motion module  130  optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns (e.g., different motions, timings, and/or intensities of detected contacts). Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (liftoff) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (liftoff) event. 
     Graphics module  132  includes various known software components for rendering and displaying graphics on touch screen  112  or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast, or other visual property) of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including, without limitation, text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations, and the like. 
     In some embodiments, graphics module  132  stores data representing graphics to be used. Each graphic is, optionally, assigned a corresponding code. Graphics module  132  receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller  156 . 
     Haptic feedback module  133  includes various software components for generating instructions used by tactile output generator(s)  167  to produce tactile outputs at one or more locations on device  100  in response to user interactions with device  100 . 
     Text input module  134 , which may be a component of graphics module  132 , provides soft keyboards for entering text in various applications (e.g., contacts  137 , e-mail  140 , IM  141 , browser  147 , and any other application that needs text input). 
     GPS module  135  determines the location of the device and provides this information for use in various applications (e.g., to telephone  138  for use in location-based dialing; to camera  143  as picture/video metadata; and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets). 
     Applications  136  may include the following modules (or sets of instructions), or a subset or superset thereof:
         Contacts module  137  (sometimes called an address book or contact list);   Telephone module  138 ;   Video conferencing module  139 ;   E-mail client module  140 ;   Instant messaging (IM) module  141 ;   Workout support module  142 ;   Camera module  143  for still and/or video images;   Image management module  144 ;   Video player module;   Music player module;   Browser module  147 ;   Calendar module  148 ;   Widget modules  149 , which may include one or more of: weather widget  149 - 1 , stocks widget  149 - 2 , calculator widget  149 - 3 , alarm clock widget  149 - 4 , dictionary widget  149 - 5 , and other widgets obtained by the user, as well as user-created widgets  149 - 6 ;   Widget creator module  150  for making user-created widgets  149 - 6 ;   Search module  151 ;   Video and music player module  152 , which merges video player module and music player module;   Notes module  153 ;   Map module  154 ; and/or   Online video module  155 .       

     Examples of other applications  136  that may be stored in memory  102  include other word processing applications, other image editing applications, drawing applications, presentation applications, JAVA-enabled applications, encryption, digital rights management, voice recognition, and voice replication. 
     In conjunction with touch screen  112 , display controller  156 , contact/motion module  130 , graphics module  132 , and text input module  134 , contacts module  137  may be used to manage an address book or contact list (e.g., stored in application internal state  192  of contacts module  137  in memory  102  or memory  370 ), including: adding name(s) to the address book; deleting name(s) from the address book; associating telephone number(s), e-mail address(es), physical address(es) or other information with a name; associating an image with a name; categorizing and sorting names; providing telephone numbers or e-mail addresses to initiate and/or facilitate communications by telephone  138 , video conference  139 , e-mail  140 , or IM  141 ; and so forth.

Additional description of the online video application can be found in U.S. Provisional Patent Application No. 60/936,562, “Portable Multifunction Device, Method, and Graphical User Interface for Playing Online Videos,” filed Jun. 20, 2007, and U.S. patent application Ser. No. 11/968,067, “Portable Multifunction Device, Method, and Graphical User Interface for Playing Online Videos,” filed Dec. 31, 2007, the contents of which are hereby incorporated by reference in their entirety. 
     Each of the above-identified modules and applications corresponds to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules may be combined or otherwise rearranged in various embodiments. For example, video player module may be combined with music player module into a single module (e.g., video and music player module  152 ,  FIG. 1A ). In some embodiments, memory  102  may store a subset of the modules and data structures identified above. Furthermore, memory  102  may store additional modules and data structures not described above. 
     In some embodiments, device  100  is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device  100 , the number of physical input control devices (such as push buttons, dials, and the like) on device  100  may be reduced. 
     The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device  100  to a main, home, or root menu from any user interface that is displayed on device  100 . In such embodiments, a “menu button” is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad. 
       FIG. 1B  is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory  102  ( FIG. 1A ) or  370  ( FIG. 3 ) includes event sorter  170  (e.g., in operating system  126 ) and a respective application  136 - 1  (e.g., any of the aforementioned applications  137 - 151 ,  155 ,  380 - 390 ). 
     Event sorter  170  receives event information and determines the application  136 - 1  and application view  191  of application  136 - 1  to which to deliver the event information. Event sorter  170  includes event monitor  171  and event dispatcher module  174 . In some embodiments, application  136 - 1  includes application internal state  192 , which indicates the current application view(s) displayed on touch-sensitive display  112  when the application is active or executing. In some embodiments, device/global internal state  157  is used by event sorter  170  to determine which application(s) is (are) currently active, and application internal state  192  is used by event sorter  170  to determine application views  191  to which to deliver event information. 
     In some embodiments, application internal state  192  includes additional information, such as one or more of: resume information to be used when application  136 - 1  resumes execution, user interface state information that indicates information being displayed or that is ready for display by application  136 - 1 , a state queue for enabling the user to go back to a prior state or view of application  136 - 1 , and a redo/undo queue of previous actions taken by the user. 
     Event monitor  171  receives event information from peripherals interface  118 . Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display  112 , as part of a multi-touch gesture). Peripherals interface  118  transmits information it receives from I/O subsystem  106  or a sensor, such as proximity sensor  166 , accelerometer(s)  168 , and/or microphone  113  (through audio circuitry  110 ). Information that peripherals interface  118  receives from I/O subsystem  106  includes information from touch-sensitive display  112  or a touch-sensitive surface. 
     In some embodiments, event monitor  171  sends requests to the peripherals interface  118  at predetermined intervals. In response, peripherals interface  118  transmits event information. In other embodiments, peripherals interface  118  transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration). 
     In some embodiments, event sorter  170  also includes a hit view determination module  172  and/or an active event recognizer determination module  173 . 
     Hit view determination module  172  provides software procedures for determining where a sub-event has taken place within one or more views when touch-sensitive display  112  displays more than one view. Views are made up of controls and other elements that a user can see on the display. 
     Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected may correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected may be called the hit view, and the set of events that are recognized as proper inputs may be determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture. 
     Hit view determination module  172  receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module  172  identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (e.g., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module  172 , the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view. 
     Active event recognizer determination module  173  determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module  173  determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module  173  determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views. 
     Event dispatcher module  174  dispatches the event information to an event recognizer (e.g., event recognizer  180 ). In embodiments including active event recognizer determination module  173 , event dispatcher module  174  delivers the event information to an event recognizer determined by active event recognizer determination module  173 . In some embodiments, event dispatcher module  174  stores in an event queue the event information, which is retrieved by a respective event receiver  182 . 
     In some embodiments, operating system  126  includes event sorter  170 . Alternatively, application  136 - 1  includes event sorter  170 . In yet other embodiments, event sorter  170  is a stand-alone module, or a part of another module stored in memory  102 , such as contact/motion module  130 . 
     In some embodiments, application  136 - 1  includes a plurality of event handlers  190  and one or more application views  191 , each of which includes instructions for handling touch events that occur within a respective view of the application&#39;s user interface. Each application view  191  of the application  136 - 1  includes one or more event recognizers  180 . Typically, a respective application view  191  includes a plurality of event recognizers  180 . In other embodiments, one or more of event recognizers  180  are part of a separate module, such as a user interface kit (not shown) or a higher level object from which application  136 - 1  inherits methods and other properties. In some embodiments, a respective event handler  190  includes one or more of: data updater  176 , object updater  177 , GUI updater  178 , and/or event data  179  received from event sorter  170 . Event handler  190  may utilize or call data updater  176 , object updater  177 , or GUI updater  178  to update the application internal state  192 . Alternatively, one or more of the application views  191  include one or more respective event handlers  190 . Also, in some embodiments, one or more of data updater  176 , object updater  177 , and GUI updater  178  are included in a respective application view  191 . 
     A respective event recognizer  180  receives event information (e.g., event data  179 ) from event sorter  170  and identifies an event from the event information. Event recognizer  180  includes event receiver  182  and event comparator  184 . In some embodiments, event recognizer  180  also includes at least a subset of: metadata  183 , and event delivery instructions  188  (which may include sub-event delivery instructions). 
     Event receiver  182  receives event information from event sorter  170 . The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch, the event information may also include speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device. 
     Event comparator  184  compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator  184  includes event definitions  186 . Event definitions  186  contain definitions of events (e.g., predefined sequences of sub-events), for example, event  1  ( 187 - 1 ), event  2  ( 187 - 2 ), and others. In some embodiments, sub-events in an event ( 187 ) include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event  1  ( 187 - 1 ) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first liftoff (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second liftoff (touch end) for a predetermined phase. In another example, the definition for event  2  ( 187 - 2 ) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display  112 , and liftoff of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers  190 . 
     In some embodiments, event definition  187  includes a definition of an event for a respective user-interface object. In some embodiments, event comparator  184  performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display  112 , when a touch is detected on touch-sensitive display  112 , event comparator  184  performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler  190 , the event comparator uses the result of the hit test to determine which event handler  190  should be activated. For example, event comparator  184  selects an event handler associated with the sub-event and the object triggering the hit test. 
     In some embodiments, the definition for a respective event ( 187 ) also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer&#39;s event type. 
     When a respective event recognizer  180  determines that the series of sub-events do not match any of the events in event definitions  186 , the respective event recognizer  180  enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture. 
     In some embodiments, a respective event recognizer  180  includes metadata  183  with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata  183  includes configurable properties, flags, and/or lists that indicate how event recognizers may interact, or are enabled to interact, with one another. In some embodiments, metadata  183  includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy. 
     In some embodiments, a respective event recognizer  180  activates event handler  190  associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer  180  delivers event information associated with the event to event handler  190 . Activating an event handler  190  is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer  180  throws a flag associated with the recognized event, and event handler  190  associated with the flag catches the flag and performs a predefined process. 
     In some embodiments, event delivery instructions  188  include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process. 
     In some embodiments, data updater  176  creates and updates data used in application  136 - 1 . For example, data updater  176  updates the telephone number used in contacts module  137 , or stores a video file used in video player module. In some embodiments, object updater  177  creates and updates objects used in application  136 - 1 . For example, object updater  177  creates a new user-interface object or updates the position of a user-interface object. GUI updater  178  updates the GUI. For example, GUI updater  178  prepares display information and sends it to graphics module  132  for display on a touch-sensitive display. 
     In some embodiments, event handler(s)  190  includes or has access to data updater  176 , object updater  177 , and GUI updater  178 . In some embodiments, data updater  176 , object updater  177 , and GUI updater  178  are included in a single module of a respective application  136 - 1  or application view  191 . In other embodiments, they are included in two or more software modules. 
     It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices  100  with input devices, not all of which are initiated on touch screens. For example, mouse movement and mouse button presses, optionally coordinated with single or multiple keyboard presses or holds; contact movements such as taps, drags, scrolls, etc. on touchpads; pen stylus inputs; movement of the device; oral instructions; detected eye movements; biometric inputs; and/or any combination thereof are optionally utilized as inputs corresponding to sub-events which define an event to be recognized. 
       FIG. 2  illustrates a portable multifunction device  100  having a touch screen  112  in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface (UI)  200 . In this embodiment, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers  202  (not drawn to scale in the figure) or one or more styluses  203  (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward), and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device  100 . In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap. 
     Device  100  may also include one or more physical buttons, such as “home” or menu button  204 . As described previously, menu button  204  may be used to navigate to any application  136  in a set of applications that may be executed on device  100 . Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on touch screen  112 . 
     In one embodiment, device  100  includes touch screen  112 , menu button  204 , push button  206  for powering the device on/off and locking the device, volume adjustment button(s)  208 , subscriber identity module (SIM) card slot  210 , headset jack  212 , and docking/charging external port  124 . Push button  206  is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval, to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, device  100  also accepts verbal input for activation or deactivation of some functions through microphone  113 . Device  100  also, optionally, includes one or more contact intensity sensors  165  for detecting intensity of contacts on touch screen  112  and/or one or more tactile output generators  167  for generating tactile outputs for a user of device  100 . 
       FIG. 3  is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device  300  need not be portable. In some embodiments, device  300  is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child&#39;s learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device  300  typically includes one or more processing units (CPUs)  310 , one or more network or other communications interfaces  360 , memory  370 , and one or more communication buses  320  for interconnecting these components. Communication buses  320  optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device  300  includes input/output (I/O) interface  330  comprising display  340 , which is typically a touch screen display.  1 /O interface  330  also optionally includes a keyboard and/or mouse (or other pointing device)  350  and touchpad  355 , tactile output generator  357  for generating tactile outputs on device  300  (e.g., similar to tactile output generator(s)  167  described above with reference to  FIG. 1A ), sensors  359  (e.g., optical, acceleration, proximity, touch-sensitive, and/or contact intensity sensors similar to contact intensity sensor(s)  165  described above with reference to  FIG. 1A ). Memory  370  includes high-speed random access memory, such as DRAM, SRAM, DDR RAM, or other random access solid state memory devices; and optionally includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory  370  optionally includes one or more storage devices remotely located from CPU(s)  310 . In some embodiments, memory  370  stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory  102  of portable multifunction device  100  ( FIG. 1A ), or a subset thereof. Furthermore, memory  370  optionally stores additional programs, modules, and data structures not present in memory  102  of portable multifunction device  100 . For example, memory  370  of device  300  optionally stores drawing module  380 , presentation module  382 , word processing module  384 , website creation module  386 , disk authoring module  388 , and/or spreadsheet module  390 , while memory  102  of portable multifunction device  100  ( FIG. 1A ) optionally does not store these modules. 
     Each of the above-identified elements in  FIG. 3  may be stored in one or more of the previously mentioned memory devices. Each of the above-identified modules corresponds to a set of instructions for performing a function described above. The above-identified modules or programs (e.g., sets of instructions) need not be implemented as separate software programs, procedures, or modules, and thus various subsets of these modules may be combined or otherwise rearranged in various embodiments. In some embodiments, memory  370  may store a subset of the modules and data structures identified above. Furthermore, memory  370  may store additional modules and data structures not described above. 
     Attention is now directed towards embodiments of user interfaces that may be implemented on, for example, portable multifunction device  100 . 
       FIG. 4A  illustrates an exemplary user interface for a menu of applications on portable multifunction device  100  in accordance with some embodiments. Similar user interfaces may be implemented on device  300 . In some embodiments, user interface  400  includes the following elements, or a subset or superset thereof:
         Signal strength indicator(s)  402  for wireless communication(s), such as cellular and Wi-Fi signals;   Time  404 ;   Bluetooth indicator  405 ;   Battery status indicator  406 ;   Tray  408  with icons for frequently used applications, such as:
           Icon  416  for telephone module  138 , labeled “Phone,” which optionally includes an indicator  414  of the number of missed calls or voicemail messages;   Icon  418  for e-mail client module  140 , labeled “Mail,” which optionally includes an indicator  410  of the number of unread e-mails;   Icon  420  for browser module  147 , labeled “Browser;” and   Icon  422  for video and music player module  152 , also referred to as iPod (trademark of Apple Inc.) module  152 , labeled “iPod;” and   
           Icons for other applications, such as:
           Icon  424  for IM module  141 , labeled “Messages;”   Icon  426  for calendar module  148 , labeled “Calendar;”   Icon  428  for image management module  144 , labeled “Photos;”   Icon  430  for camera module  143 , labeled “Camera;”   Icon  432  for online video module  155 , labeled “Online Video;”   Icon  434  for stocks widget  149 - 2 , labeled “Stocks;”   Icon  436  for map module  154 , labeled “Maps;”   Icon  438  for weather widget  149 - 1 , labeled “Weather,”   Icon  440  for alarm clock widget  149 - 4 , labeled “Clock;”   Icon  442  for workout support module  142 , labeled “Workout Support;”   Icon  444  for notes module  153 , labeled “Notes;” and   Icon  446  for a settings application or module, labeled “Settings,” which provides access to settings for device  100  and its various applications  136 .   
               

     It should be noted that the icon labels illustrated in  FIG. 4A  are merely exemplary. For example, icon  422  for video and music player module  152  may optionally be labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon. 
       FIG. 4B  illustrates an exemplary user interface on a device (e.g., device  300 ,  FIG. 3 ) with a touch-sensitive surface  451  (e.g., a tablet or touchpad  355 ,  FIG. 3 ) that is separate from the display  450  (e.g., touch screen display  112 ). Device  300  also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors  357 ) for detecting intensity of contacts on touch-sensitive surface  451  and/or one or more tactile output generators  359  for generating tactile outputs for a user of device  300 . 
     Although some of the examples which follow will be given with reference to inputs on touch screen display  112  (where the touch-sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in  FIG. 4B . In some embodiments, the touch-sensitive surface (e.g.,  451  in  FIG. 4B ) has a primary axis (e.g.,  452  in  FIG. 4B ) that corresponds to a primary axis (e.g.,  453  in  FIG. 4B ) on the display (e.g.,  450 ). In accordance with these embodiments, the device detects contacts (e.g.,  460  and  462  in  FIG. 4B ) with the touch-sensitive surface  451  at locations that correspond to respective locations on the display (e.g., in  FIG. 4B, 460  corresponds to  468  and  462  corresponds to  470 ). In this way, user inputs (e.g., contacts  460  and  462 , and movements thereof) detected by the device on the touch-sensitive surface (e.g.,  451  in  FIG. 4B ) are used by the device to manipulate the user interface on the display (e.g.,  450  in  FIG. 4B ) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein. 
     Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse-based input or stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously. 
     As used here, the term “affordance” refers to a user-interactive graphical user interface object that may be displayed on the display screen of devices  100 ,  300 , and/or  500  ( FIGS. 1, 3, and 5 ). For example, an image (e.g., icon), a button, and text (e.g., hyperlink) may each constitute an affordance. 
     As used herein, the term “focus selector” refers to an input element that indicates a current part of a user interface with which a user is interacting. In some implementations that include a cursor or other location marker, the cursor acts as a “focus selector” so that when an input (e.g., a press input) is detected on a touch-sensitive surface (e.g., touchpad  355  in  FIG. 3  or touch-sensitive surface  451  in  FIG. 4B ) while the cursor is over a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations that include a touch screen display (e.g., touch-sensitive display system  112  in  FIG. 1A  or touch screen  112  in  FIG. 4A ) that enables direct interaction with user interface elements on the touch screen display, a detected contact on the touch screen acts as a “focus selector” so that when an input (e.g., a press input by the contact) is detected on the touch screen display at a location of a particular user interface element (e.g., a button, window, slider, or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations, focus is moved from one region of a user interface to another region of the user interface without corresponding movement of a cursor or movement of a contact on a touch screen display (e.g., by using a tab key or arrow keys to move focus from one button to another button); in these implementations, the focus selector moves in accordance with movement of focus between different regions of the user interface. Without regard to the specific form taken by the focus selector, the focus selector is generally the user interface element (or contact on a touch screen display) that is controlled by the user so as to communicate the user&#39;s intended interaction with the user interface (e.g., by indicating, to the device, the element of the user interface with which the user is intending to interact). For example, the location of a focus selector (e.g., a cursor, a contact, or a selection box) over a respective button while a press input is detected on the touch-sensitive surface (e.g., a touchpad or touch screen) will indicate that the user is intending to activate the respective button (as opposed to other user interface elements shown on a display of the device). 
     As used in the specification and claims, the term “characteristic intensity” of a contact refers to a characteristic of the contact based on one or more intensities of the contact. In some embodiments, the characteristic intensity is based on multiple intensity samples. The characteristic intensity is, optionally, based on a predefined number of intensity samples, or a set of intensity samples collected during a predetermined time period (e.g., 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10 seconds) relative to a predefined event (e.g., after detecting the contact, prior to detecting liftoff of the contact, before or after detecting a start of movement of the contact, prior to detecting an end of the contact, before or after detecting an increase in intensity of the contact, and/or before or after detecting a decrease in intensity of the contact). A characteristic intensity of a contact is, optionally based on one or more of: a maximum value of the intensities of the contact, a mean value of the intensities of the contact, an average value of the intensities of the contact, a top 10 percentile value of the intensities of the contact, a value at the half maximum of the intensities of the contact, a value at the 90 percent maximum of the intensities of the contact, or the like. In some embodiments, the duration of the contact is used in determining the characteristic intensity (e.g., when the characteristic intensity is an average of the intensity of the contact over time). In some embodiments, the characteristic intensity is compared to a set of one or more intensity thresholds to determine whether an operation has been performed by a user. For example, the set of one or more intensity thresholds may include a first intensity threshold and a second intensity threshold. In this example, a contact with a characteristic intensity that does not exceed the first threshold results in a first operation, a contact with a characteristic intensity that exceeds the first intensity threshold and does not exceed the second intensity threshold results in a second operation, and a contact with a characteristic intensity that exceeds the second threshold results in a third operation. In some embodiments, a comparison between the characteristic intensity and one or more thresholds is used to determine whether or not to perform one or more operations (e.g., whether to perform a respective operation or forgo performing the respective operation) rather than being used to determine whether to perform a first operation or a second operation. 
     In some embodiments, a portion of a gesture is identified for purposes of determining a characteristic intensity. For example, a touch-sensitive surface may receive a continuous swipe contact transitioning from a start location and reaching an end location, at which point the intensity of the contact increases. In this example, the characteristic intensity of the contact at the end location may be based on only a portion of the continuous swipe contact, and not the entire swipe contact (e.g., only the portion of the swipe contact at the end location). In some embodiments, a smoothing algorithm may be applied to the intensities of the swipe contact prior to determining the characteristic intensity of the contact. For example, the smoothing algorithm optionally includes one or more of: an unweighted sliding-average smoothing algorithm, a triangular smoothing algorithm, a median filter smoothing algorithm, and/or an exponential smoothing algorithm. In some circumstances, these smoothing algorithms eliminate narrow spikes or dips in the intensities of the swipe contact for purposes of determining a characteristic intensity. 
     The intensity of a contact on the touch-sensitive surface may be characterized relative to one or more intensity thresholds, such as a contact-detection intensity threshold, a light press intensity threshold, a deep press intensity threshold, and/or one or more other intensity thresholds. In some embodiments, the light press intensity threshold corresponds to an intensity at which the device will perform operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, the deep press intensity threshold corresponds to an intensity at which the device will perform operations that are different from operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, when a contact is detected with a characteristic intensity below the light press intensity threshold (e.g., and above a nominal contact-detection intensity threshold below which the contact is no longer detected), the device will move a focus selector in accordance with movement of the contact on the touch-sensitive surface without performing an operation associated with the light press intensity threshold or the deep press intensity threshold. Generally, unless otherwise stated, these intensity thresholds are consistent between different sets of user interface figures. 
     An increase of characteristic intensity of the contact from an intensity below the light press intensity threshold to an intensity between the light press intensity threshold and the deep press intensity threshold is sometimes referred to as a “light press” input. An increase of characteristic intensity of the contact from an intensity below the deep press intensity threshold to an intensity above the deep press intensity threshold is sometimes referred to as a “deep press” input. An increase of characteristic intensity of the contact from an intensity below the contact-detection intensity threshold to an intensity between the contact-detection intensity threshold and the light press intensity threshold is sometimes referred to as detecting the contact on the touch-surface. A decrease of characteristic intensity of the contact from an intensity above the contact-detection intensity threshold to an intensity below the contact-detection intensity threshold is sometimes referred to as detecting liftoff of the contact from the touch-surface. In some embodiments the contact-detection intensity threshold is zero. In some embodiments, the contact-detection intensity threshold is greater than zero. 
     In some embodiments described herein, one or more operations are performed in response to detecting a gesture that includes a respective press input or in response to detecting the respective press input performed with a respective contact (or a plurality of contacts), where the respective press input is detected based at least in part on detecting an increase in intensity of the contact (or plurality of contacts) above a press-input intensity threshold. In some embodiments, the respective operation is performed in response to detecting the increase in intensity of the respective contact above the press-input intensity threshold (e.g., a “down stroke” of the respective press input). In some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the press-input threshold (e.g., an “up stroke” of the respective press input). 
     In some embodiments, the device employs intensity hysteresis to avoid accidental inputs sometimes termed “jitter,” where the device defines or selects a hysteresis intensity threshold with a predefined relationship to the press-input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press-input intensity threshold or the hysteresis intensity threshold is 75%, 90%, or some reasonable proportion of the press-input intensity threshold). Thus, in some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the hysteresis intensity threshold that corresponds to the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the hysteresis intensity threshold (e.g., an “up stroke” of the respective press input). Similarly, in some embodiments, the press input is detected only when the device detects an increase in intensity of the contact from an intensity at or below the hysteresis intensity threshold to an intensity at or above the press-input intensity threshold and, optionally, a subsequent decrease in intensity of the contact to an intensity at or below the hysteresis intensity, and the respective operation is performed in response to detecting the press input (e.g., the increase in intensity of the contact or the decrease in intensity of the contact, depending on the circumstances). 
     For ease of explanation, the descriptions of operations performed in response to a press input associated with a press-input intensity threshold or in response to a gesture including the press input are, optionally, triggered in response to detecting either: an increase in intensity of a contact above the press-input intensity threshold, an increase in intensity of a contact from an intensity below the hysteresis intensity threshold to an intensity above the press-input intensity threshold, a decrease in intensity of the contact below the press-input intensity threshold, and/or a decrease in intensity of the contact below the hysteresis intensity threshold corresponding to the press-input intensity threshold. Additionally, in examples where an operation is described as being performed in response to detecting a decrease in intensity of a contact below the press-input intensity threshold, the operation is, optionally, performed in response to detecting a decrease in intensity of the contact below a hysteresis intensity threshold corresponding to, and lower than, the press-input intensity threshold. 
     As used herein, an “installed application” refers to a software application that has been downloaded onto an electronic device (e.g., devices  100 ,  300 , and/or  500 ) and is ready to be launched (e.g., become opened) on the device. In some embodiments, a downloaded application becomes an installed application by way of an installation program that extracts program portions from a downloaded package and integrates the extracted portions with the operating system of the computer system. 
     As used herein, the term “open application” or “executing application” refers to a software application with retained state information (e.g., as part of device/global internal state  157  and/or application internal state  192 ). An open or executing application may be any one of the following types of applications:
         an active application, which is currently displayed on a display screen of the device that the application is being used on;   a background application (or background processes), which is not currently displayed, but one or more processes for the application are being processed by one or more processors; and   a suspended or hibernated application, which is not running, but has state information that is stored in memory (volatile and non-volatile, respectively) and that can be used to resume execution of the application.       

     As used herein, the term “closed application” refers to software applications without retained state information (e.g., state information for closed applications is not stored in a memory of the device). Accordingly, closing an application includes stopping and/or removing application processes for the application and removing state information for the application from the memory of the device. Generally, opening a second application while in a first application does not close the first application. When the second application is displayed and the first application ceases to be displayed, the first application becomes a background application. 
     3. User Interfaces and Associated Processes 
     Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that may be implemented on an electronic device with a display and a touch-sensitive surface, such as device  300  or portable multifunction device  100 . 
       FIGS. 5A-5E  illustrate exemplary user interfaces for representing and tracking battery usage of a device. The user interfaces in these figures are used to illustrate the processes described below, including the processes described below with reference to  FIGS. 8-10 . 
       FIG. 5A  illustrates an exemplary user interface for navigating to a battery usage user interface. User interface  500  can be displayed on a touch-sensitive display of a device (e.g., touch-sensitive display system  112  of device  100 ) and can responsive to gestures on a touch-sensitive surface. In some embodiments, the display and touch sensitive surface can be separate elements and in other embodiments, the display and touch sensitive surface can be a display with a touch sensitive surface (e.g., touch-sensitive display system  112  of device  100 ). User interface  500  can includes a general settings page with various user interface elements for accessing information about and settings for the device. For examples, as illustrated in  FIG. 5A , user interface  500  includes user interface elements for information about the device (“About”) and device software (“Software Update”). User interface  500  can also include user interface elements for information and settings about a voice assistant (“Siri”), search utility (“Spotlight Search”), text size of the device (“Text Size”), various accessibility features (“Accessibility”), and a background application refresh utility (“Background App Refresh”). The user interface  500  can also include a user interface element  501  for accessing battery usage of the device (“Battery Usage”). The user interface element  501  can include an indicator, such as arrow  503 , to indicate to the user that activating the user interface element  501  causes navigation to another user interface. A gesture, such as a tap gesture, can be detected on touch sensitive surface  451  at user interface element  501  for battery usage of the device to navigate to the battery usage user interface. 
       FIG. 5B  illustrates an exemplary battery usage user interface  510  that may be displayed in response to a gesture on interface element  501  of  FIG. 5A . Battery usage user interface  510  includes a plurality of sections and a plurality of user interface elements, such as a section  512  corresponding to usage statistics since a last full charge (“TIME SINCE LAST FULL CHARGE”), a section  514  corresponding to suggestions to improve battery life (“BATTERY LIFE SUGGESTIONS”), and a section  516  corresponding to battery usage attributed to various items (“BATTERY USAGE”), such as various software applications. Section  512  includes a representation  512 - 1  of the amount of time the device has been awake and in use (e.g. making a call, using email, listening to music, browsing the web, sending and receiving text messages, or during certain background tasks such as auto-checking email, etc.) since the last full charge (“Usage”) and a representation  512 - 2  of the amount of time the device has been powered on including the time the device has been asleep (“Standby”). 
     Attention is now directed to section  516  of user interface  510 , which provides information regarding battery usage attributed to various items, such as software applications. Section  516  includes user interface element  516 - 1  for selecting display of battery usage over a first time period (“Last 24 Hours,” as shown) and a user interface element  516 - 2  for selecting display of batter usage over a second time period (“Last 7 Days,” as shown). In some embodiments, battery usage is displayed for a time period that is based on a period of operation of the device, such as the last 24 hours of device operation or state (e.g., standby), even when those 24 operating hours span a calendar period of several days. In other embodiments, battery usage is displayed for a time period that is based on calendar days, irrespective of device operation or state. 
     In some embodiments, a selected time period (e.g., 24 hours) is designated as the default time period shown, when user interface  510  is generated in response to a request to display a battery usage user interface. In embodiments having a default time period designated for display, display of battery usage for a non-default time period (e.g., 7 days) may be requested by selecting a user interface element, such as element  516 - 2 . In  FIG. 5B , battery usage is currently shown for the last 24 hours, as indicated by the bolding of user interface element  516 - 1 . In the exemplary interface of  FIG. 5B , tracked battery usage is shown for five items as percentages of total usage: Phone application  516 - 3  (40%), Camera application  516 - 4  (25%), Maps application  516 - 5  (20%), Mail application  516 - 6  (14%), and Music application  516 - 7  (1%). As shown, the items are ordered by decreasing percentage of battery usage. In other embodiments, displayed items may be ordered or sorted according alternative orders such as alphabetical order, most recent usage, or the like. In  FIG. 5B , battery usage for each item is shown as a percentage of the battery usage for the selected time interval (e.g., 24 hours), with 100% of the battery usage for the device attributable to the five items shown. In other embodiments, battery usage for an item may be shown in alternative formats such as a fraction of total usage, as an absolute value (e.g., amps or milliamps), or the like. The sum of the battery usage of the items shown may be less than 100% in other embodiments. Alternative embodiments of battery usage section  516  may display only items meeting certain criteria, such as items having usage that exceeds a certain threshold (e.g., greater than 1%). In some embodiments, additional items may be accessible by scrolling the screen, selecting a provided interface object, or not shown at all. 
     The device (e.g., device  100 ) may determine the battery usage value associated with each item according to a number of methods. In some embodiments, device  100  continuously or periodically monitors battery usage by one or more hardware subsystems/components or software subsystems/components, such as those shown in  FIG. 3 . For example, device  100  may monitor power drawn by display system  112  (e.g., from a display backlight), processor(s)  120  (e.g., a central processor or a graphics processor), a wireless antenna, a software extension associated with an active application, or a daemon (e.g., a notification daemon) running on device  100 . In one embodiment, all battery usage occurring while an application (e.g., phone application  516 - 3 ) is active is attributed to that application. If a second application (e.g., camera application  516 - 4 ) becomes active on device  100 , battery usage occurring during the period of activity of the second application is attributed to that application. In another embodiment, battery usage by a given subsystem (e.g., processor(s)  120 ) may be attributed to active and background applications according to a distributed model. For example, a percentage (e.g., 60%) of processor battery usage, resulting from execution of a first operating system process, may be attributed to an active application (e.g., phone application  516 - 3 ) while a second percentage (e.g., 40%) of processor battery usage is attributed to background processes/activity associated with another application (e.g., mail application  516 - 6 ). In some embodiments, battery usage associated with selected hardware or software subsystems is excluded from monitoring or excluded from the calculation of total battery usage. For example, battery usage associated with baseline, operating system functions may be excluded from the calculation of total battery usage such that calculated and/or displayed battery usage is only based on usage attributed to selected (e.g., discretionary) items, such as an active software application (e.g., phone application  516 - 3 ). In other embodiments, battery usage resulting from system processes and activities that primarily benefit an application (e.g., mail application  516 - 6 ) are attributed to the application, even if the application is not the active application when battery usage occurs. For example, battery usage resulting from pulling mail messages may include waking up a wireless antenna and connecting to a mail server is attributed to the mail application even if the mail application was not active/open during the battery usage. In some embodiments battery usage caused by background activity for the benefit of the second application is similarly attributed to the second application. 
     By monitoring, attributing, and displaying battery usage according to designated items, particular software applications, device  100  provides the information in a more salient format, more closely linked to particular function and uses of the device. Users can more readily connect the information to their use of the device and its functions and, should they desire, adjust their use to conserve battery life. 
     In some embodiments, device  100  monitors and logs battery usage, but does not calculate and/or attribute battery usage values until a request for display of a battery usage interface (e.g., interface  510 ) is received by device  100 . In other embodiments, battery usage values are calculated on a continuous or periodic basis, independent of requests for display of a battery usage interface (e.g., interface  510 ). In some embodiments, such as the embodiment of  FIG. 5B , battery usage information is specifically not attributed and displayed directly to hardware subsystems. In such embodiments, items associated with battery usage may be limited to software applications and all monitored batter usage from hardware subsystems is attributed to, and distributed between, to those software applications. 
     Battery usage attributed to one or more items may be displayed with qualifier information. As seen in  FIG. 5B , battery usage attributed to maps application  516 - 5  is displayed with the qualifier “Location.” Similarly, battery usage attributed to Mail application  516 - 6  is displayed with qualifier “Background Activity.” Through the use of qualifiers, device  100  may provide the user with additional information to signal exceptional, atypical, or notable battery usage scenarios that may be relevant to the user&#39;s use patterns for an application or impact battery life for the device. Device  100  may display one or more qualifiers with battery usage information for an item based on a determination that qualifier display criteria are met and not display such qualifiers when the criteria are not met. Qualifier criteria may include, but is not limited to, criteria relating to comparative battery usage statistics, both within the set of battery usage statistics attributable to a particular item (e.g., software application) and to the device as a whole. For example, criteria may include a percentage of battery usage attributable to a particular item from a particular subsystem (e.g., wireless antenna) exceeding a minimum threshold (e.g., 30%) of total battery usage of the device or attributable to the particular item alone. With reference to the qualifier “Location” displayed with maps application  516 - 5 , the criteria may be battery usage associated with one or more location-affiliated hardware subsystems attributable to the map application exceeding 30% of total battery usage associated with the maps application and also exceeding 1% of total battery usage across the device for the relevant time period. Similarly, qualifier “background activity” may be displayed with mail application  516 - 6  when software and hardware subsystems attributable to the mail application, while running in a background state, exceed 30% of total battery usage associated with the mail application and also exceeds at 1% of total battery usage across the device for the relevant time period. Other qualifier criteria may include, but is not limited to, application status (e.g., background or foreground/active), discretionary settings (e.g., high brightness), network/environmental factors such as poor network or cellular signal causing higher-than-usual battery usage from antennas, specific application extensions such as AirPlay and AirDrop extensions provided by Apple Inc., time of usage (e.g., time of day or minutes of consecutive usage). Note that, depending on the qualifier criteria and the pattern of battery usage, a qualifier may be displayed when usage is displayed according to a first time period (e.g., “Last 24 Hours”), but not displayed when a second time period is displayed (e.g., “Last 7 Days”). Accordingly, in some embodiments, even though a qualifier is displayed for the first time period, the qualifier is not necessarily also displayed for a second time period if the exceptional battery usage during the second period does not meet the qualifier display criteria. In some embodiments, the qualifier display criteria are set at a level that generally results in a minimal use of qualifiers in the battery usage interface so as to draw the user&#39;s attention to exceptional use that might be surprising to the user without cluttering the user interface with qualifiers that the user is not concerned with. This may achieved, for example, by setting a maximum number of qualifiers that can be displayed in conjunction with the use of additional criteria (e.g., total battery usage) for selecting qualifiers for display when the maximum number of criteria is exceeded. In some embodiments, multiple qualifiers may be displayed for a single item. In one embodiment where multiple qualifiers are identified for display, device  100  provides a single, aggregate qualifier based on the multiple identified qualifiers. For example, device  100  may determine that the separate qualifiers “Background Activity” and “Location” are applicable to the battery usage attributed to a software application and then aggregate the two qualifiers to display “Background Location.” In another embodiment, one or more elements of multiple qualifiers may be truncated. For example, device  100  may determine that the separate qualifiers “poor cellular signal” and “audio” are applicable to the battery usage attributed to a software application and then truncate the first qualifier to display “poor cellular, audio,” thereby reducing screen clutter. In another embodiment, device  100  may have logic governing or suppressing the display of multiple qualifiers, based on relationships between the qualifiers. Device  100  may determine that the separate qualifiers “location” and “antenna” are applicable to the battery usage attributed to a software application and then truncate the “antenna” qualifier to display just “location,” because a user would understand that “location” services make extensive use of antennas. 
       FIG. 5C  illustrates another exemplary battery usage user interface  520  that may be displayed in response to a gesture on interface element  501  of  FIG. 5A . Section  521  of user interface  520  provides information regarding battery usage attributed to various items. In the embodiment of  FIG. 5C , battery usage defaults to display for usage over a time period that is based on the period of operation of the device. The embodiment of  FIG. 5C  may be particularly useful, for example, during a period of initial operation of a device (e.g., a newly activated device). As operation of the device continues and exceeds certain time thresholds, the battery usage user interface may display interface options for additional time periods (or default to alternative time periods), as seen in  FIG. 5B . 
       FIG. 5D  illustrates yet another exemplary battery usage user interface  530 . Interface  530  is primarily dedicated to section  531 , provides information regarding battery usage attributed to various items. In some embodiments, user interface  530  may be displayed directly in response to a gesture on interface element  501  of  FIG. 5A . In other embodiments, user interface  530  is displayed in response to a request to display an expanded section  531 , starting from an interface having a smaller section for providing information regarding battery usage attributed to various items. As seen in  FIG. 5D , battery usage resulting from a hardware or software subsystem common to several applications may aggregated and then attributed as a separate item, while not attributing that battery usage to the several applications. For example, a battery usage interface (e.g., interfaces  510 ,  520 , or  530 ) may include a separate item  532 - 1 , and associated battery usage, for “no cellular signal,” (i.e., battery usage primarily resulting from a high level of cellular antennae activity due to the absence of a cellular reception) without attributing that battery usage, in whole or in part, to several applications that commonly require cellular signal. Similarly, battery usage from a software subsystem (e.g., a software personal assistant subsystem or one or more software subsystems associated with a home screen, a lock screen, or a notification screen) that may be commonly used by several applications may be included as a separate item, with associated battery usage, in a battery usage interface, without attributing battery usage from the software subsystem, in whole or in part, to several applications that commonly use the software subsystem. 
       FIG. 5E  illustrates a battery usage histogram user interface  540  that may be displayed directly in response to a gesture on interface element  501  of  FIG. 5A  or in response to a request received while displaying any of interfaces  5 B to  5 D. User interface  540  displays changes in battery percentage (e.g., usage and charging) as a function of time. 
     Attention is now directed back to  FIG. 5B , and to section  514  of user interface  510 , in particular. Section  514  provides recommendations of actions (e.g., enabling options such as auto-lock or auto-brightness) or settings that may be used to improve battery life. In some embodiments, section  514  or particular suggestions of section  514  are displayed only in response to a determination that battery savings suggestion criteria have been met and are not displayed when such criteria are not met. For example, a suggestion to enable auto-lock ( 514 - 1 ) may only be displayed if device  100  determines, based on historical battery usage, that enabling auto-lock would improve battery usage, with or without a minimum improvement threshold value (e.g., at 1%, 2%, or 5%). Similarly, a suggestion to enable auto-brightness ( 514 - 2 ) may only be displayed if device  100  determine, based on historical battery usage, that enabling auto-brightness would improve battery usage. Upon receiving an input on a battery savings suggestion, device  100  may provide the user with an interface for adopting the battery savings suggestion. In other embodiments, battery savings suggestions may include suggestions to enable or disable wireless connectivity or a cellular protocol (e.g., LTE), and configure application parameters (e.g., mail fetch parameters). In one embodiment, device  100  monitors and logs or records one or more device operational parameters to determine whether a battery savings suggestion criteria would be met. For example, device  100  may log or record ambient light values to determine if enabling auto-brightness would result in a predicted improvement in battery usage. 
       FIG. 6  illustrates an exemplary user interface  600  for adopting an enable auto-lock battery savings suggestion on device  100 . In some embodiments, the user interface of  FIG. 6  is a user interface also accessible from a settings option or application of device  100 . In other embodiments, the user interface of  FIG. 6  is specially provided in response to a request made from a battery usage interface. Similarly,  FIG. 7  illustrates an exemplary user interface  700  for adopting an enable auto-brightness battery savings suggestion on device  100 . 
       FIG. 8  is a flow diagram illustrating process  800  for tracking battery usage. Process  800  may be performed at an electronic device with one or more processors and memory, like device  100  ( FIGS. 1A-1B ) and device  300  ( FIG. 3 ). At block  802 , the device attributes a portion of battery usage of a first hardware subsystem to a first application based on the battery usage of the first hardware subsystem that occurred during activity by the first application. At block  804 , the device attributes a portion of the battery usage of the first hardware subsystem to a second application based on the battery usage of the first hardware subsystem that occurred during activity by the second application. Optionally, at block  804 , the device may attribute a portion of battery usage of a second hardware subsystem to the first application based on the battery usage of the second hardware subsystem that occurred during activity by the first application and attribute a portion of the battery usage of the second hardware subsystem to the second application based on the battery usage of the second hardware subsystem that occurred during activity by the second application. Optionally, at block  804 , the device may attribute a portion of battery usage of a first software subsystem to the first application based on the battery usage of the first software subsystem that occurred during activity by the first application and attribute a portion of the battery usage of the first software subsystem to the second application based on the battery usage of the first software subsystem that occurred during activity by the second application. At block  806 , the device receives a request (e.g., request received in interface of  FIG. 5A ) to display a battery usage user interface. At block  808 , in response to the request, the device displays the battery usage user interface (e.g.,  FIG. 5A-5E ) that includes a representation of the battery usage attributed to the first application and a representation of the battery usage attributed the second application. 
     Note that details of the processes described above with respect to process  800  (e.g.,  FIG. 8 ) are also applicable in an analogous manner to the processes described below. For example, processes  900  and  1000  may include one or more of the characteristics of the various processes described above with reference to process  800 . For brevity, these details are not repeated above. The various methods and techniques described above with reference to process  800  may be optionally implemented as one or more units, such as those described with regard to  FIG. 11 . 
     The operations described above with reference to the figures may be implemented by components depicted in  FIGS. 1A-1B . For example, attribution operations, request operations, and display operations may be implemented by event sorter  170 , event recognizer  180 , and event handler  190 . Event monitor  171  in event sorter  170  detects a contact on touch-sensitive display  112 , and event dispatcher module  174  delivers the event information to application  136 - 1 . A respective event recognizer  180  of application  136 - 1  compares the event information to respective event definitions  186 , and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer  180  activates an event handler  190  associated with the detection of the event or sub-event. Event handler  190  may utilize or call data updater  176  or object updater  177  to update the application internal state  192 . In some embodiments, event handler  190  accesses a respective GUI updater  178  to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in  FIGS. 1A-1B . 
       FIG. 9  is a flow diagram illustrating method  900  for tracking battery usage. Method  900  may be performed at an electronic device with one or more processors and memory, like device  100  ( FIGS. 1A-1B ) and device  300  ( FIG. 3 ). At block  902 , the device determines battery usage attributed to a first application over a first time period. The battery usage attributed to the first application over the first time period includes exceptional battery usage that occurred during the first time period. At block  904 , the device receives a request to display a battery usage user interface (e.g., request received in interface of  FIG. 5A ). At block  906 , in response to receiving the request, and in accordance with a determination that the exceptional battery usage attributed to the first application that occurred during the first time period meets qualifier display criteria, the device displays a representation of battery usage (e.g.,  FIG. 5A-5E ) attributed to the first application over the first time period that includes qualifier information that is indicative of one or more causes of the exceptional battery usage attributed to the first application over the first time period. At block  908 , in response to receiving the request, and in accordance with a determination that the exceptional battery usage attributed to the first application that occurred during the first time period does not meet the qualifier display criteria, displaying a representation of battery usage (e.g.,  FIG. 5A-5E , without qualifiers) attributed to the first application over the first time period that does not include the qualifier information. 
     Note that details of the processes described above with respect to process  900  (e.g.,  FIG. 9 ) are also applicable in an analogous manner to the processes described below. For example, processes  800  and  1000  may include one or more of the characteristics of the various processes described above with reference to process  900 . For brevity, these details are not repeated above.

For example, determination operations, request operations, and display operations may be implemented by event sorter  170 , event recognizer  180 , and event handler  190 . Event monitor  171  in event sorter  170  detects a contact on touch-sensitive display  112 , and event dispatcher module  174  delivers the event information to application  136 - 1 . A respective event recognizer  180  of application  136 - 1  compares the event information to respective event definitions  186 , and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer  180  activates an event handler  190  associated with the detection of the event or sub-event. Event handler  190  may utilize or call data updater  176  or object updater  177  to update the application internal state  192 . In some embodiments, event handler  190  accesses a respective GUI updater  178  to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in  FIGS. 1A-1B . 
       FIG. 10  is a flow diagram illustrating process  1000  for tracking battery usage. 
     Process  1000  may be performed at an electronic device with one or more processors and memory, like device  100  ( FIGS. 1A-1B ) and device  300  ( FIG. 3 ). At block  1002 , the device receives a request to display a battery usage user interface (e.g., request received in interface of  FIG. 5A ). At block  1004 , the device determines whether battery savings suggestion criteria have been met for a first setting. At block  1006 , in response to the request, and in accordance with a determination that the battery savings suggestion criteria have been met for the first setting, the device displays a battery usage interface that includes a suggestion for adjusting the first setting (e.g.,  FIGS. 5A-5C ). At block  1008 , in response to the request, and in accordance with a determination that the battery savings suggestion criteria have not been met for the first setting, the device displays a battery usage interface (e.g.,  FIG. 5D ) that does not include the suggestion for adjusting the first setting. 
     Note that details of the processes described above with respect to process  1000  (e.g.,  FIG. 10 ) are also applicable in an analogous manner to the processes described below. For example, processes  800  and  900  may include one or more of the characteristics of the various processes described above with reference to process  1000 . For brevity, these details are not repeated above. The various methods and techniques described above with reference to process  1000  may be optionally implemented as one or more units, such as those described with regard to  FIG. 11 .

Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in  FIGS. 1A-1B . 
     As shown in  FIG. 11 , an electronic device  1100  includes a display unit  1102  configured to display a user interface, an optional touch-sensitive surface unit  1104  configured to receive user contacts; and a processing unit  1106  coupled to the display unit  1102  and the touch-sensitive surface unit  1104 . In some embodiments, the processing unit  1106  includes a display enabling unit  1108 , a receiving unit  1110 , a determining unit  1112 , and an attributing unit  1114 . The units of  FIG. 11  may be used to implement the various techniques and methods described above with respect to  FIGS. 5-10 . 
     In some embodiments, the display enabling unit  1108  is configured to cause a display of a user interface (or portions of a user interface) in conjunction with the display unit  1102 . For example, the display enabling unit  1108  may be used for: displaying the battery usage user interface that includes a representation of the battery usage attributed to the first application and a representation of the battery usage attributed the second application; displaying a representation of battery usage attributed to the first application over the first time period that includes qualifier information that is indicative of one or more causes of the exceptional battery usage attributed to the first application over the first time period; displaying a representation of battery usage attributed to the first application over the first time period that does not include the qualifier information; displaying a battery usage interface that includes a suggestion for adjusting the first setting: and displaying a battery usage interface that does not include the suggestion for adjusting the first setting. 
     In some embodiments, the receiving unit  1110  is configured to receive input. The input may be received, for example, through the use of the touch-sensitive surface unit  1104 . In some embodiments, the input may be received, for example, through the use of the input/output (I/O) interface  330  shown in  FIG. 3 . For example, the receiving unit  1110  may be used for: receiving a request to display a battery usage user interface. 
     In some embodiments, the determining unit  1112  is configured to make determinations. For example, the determining unit  1112  may be used for: determining battery usage attributed to a first application over a first time period, wherein the battery usage attributed to the first application over the first time period includes exceptional battery usage that occurred during the first time period; and determining whether battery savings suggestion criteria have been met for a first setting. 
     In some embodiments, the attributing unit  1114  is configured to attribute information. For example, the attributing unit  1114  may be used for: attributing a portion of battery usage of a first hardware subsystem to a first application based on the battery usage of the first hardware subsystem that occurred during activity by the first application; and attributing a portion of the battery usage of the first hardware subsystem to a second application based on the battery usage of the first hardware subsystem that occurred during activity by the second application.
