A method comprising: at an electronic device having a display: while the electronic device is in a first mode, displaying on the display, a first user interface including: a first time indicator indicating a current time and displayed at a first size; and a first graphical object displayed at a second size, wherein the first graphical object includes information from an associated application; and detecting that the electronic device has met criteria for transitioning from the first mode to a second mode, wherein the criteria for transitioning from the first mode to the second mode includes a criterion that is met after the electronic device fails to detect user input for a predetermined period of time; and in response to detecting that the electronic device has met the criteria for transitioning from the first mode to the second mode, transitioning the electronic device from the first mode to the second mode; while the electronic device is in the second mode, displaying on the display, a second user interface including: a second time indicator indicating the current time, wherein the second time indicator is displayed at a third size that is smaller than the first size, at which the first time indicator was previously displayed; and a second graphical object corresponding to the first graphical object, wherein the second graphical object is displayed at a fourth size that is smaller than the second size, at which the first graphical object was previously displayed. while the electronic device is in a first mode, displaying on the display, a first user interface including: a first time indicator indicating a current time and displayed at a first size; and a first graphical object displayed at a second size, wherein the first graphical object includes information from an associated application; and a first time indicator indicating a current time and displayed at a first size; and a first graphical object displayed at a second size, wherein the first graphical object includes information from an associated application; and detecting that the electronic device has met criteria for transitioning from the first mode to a second mode, wherein the criteria for transitioning from the first mode to the second mode includes a criterion that is met after the electronic device fails to detect user input for a predetermined period of time; and in response to detecting that the electronic device has met the criteria for transitioning from the first mode to the second mode, transitioning the electronic device from the first mode to the second mode; while the electronic device is in the second mode, displaying on the display, a second user interface including: a second time indicator indicating the current time, wherein the second time indicator is displayed at a third size that is smaller than the first size, at which the first time indicator was previously displayed; and a second graphical object corresponding to the first graphical object, wherein the second graphical object is displayed at a fourth size that is smaller than the second size, at which the first graphical object was previously displayed. a second time indicator indicating the current time, wherein the second time indicator is displayed at a third size that is smaller than the first size, at which the first time indicator was previously displayed; and a second graphical object corresponding to the first graphical object, wherein the second graphical object is displayed at a fourth size that is smaller than the second size, at which the first graphical object was previously displayed.
