     The temperature sensor  280 K is configured to detect a temperature. In some embodiments, the terminal device  200  executes a temperature processing policy based on the temperature detected by the temperature sensor  280 K. For example, when the temperature reported by the temperature sensor  280 K exceeds a threshold, the terminal device  200  lowers performance of a processor near the temperature sensor  280 K, to reduce power consumption to implement thermal protection. In some other embodiments, when the temperature is less than another threshold, the terminal device  200  heats the battery  242  to prevent the terminal device  200  from being abnormally powered off because of the low temperature.

     The following specifically describes an information processing method provided in the embodiments of this application with reference to  FIG. 1  and  FIG. 2 . 
     It should be noted that, in the following embodiments of this application, names of messages between network elements, names of parameters in messages, or the like are merely examples, and there may be other names during specific implementation. This is not specifically limited in the embodiments of this application. 
     It may be understood that, in the embodiments of this application, a terminal device may perform some or all of steps in the embodiments of this application. These steps are merely examples. In the embodiments of this application, the terminal device may also perform other steps or variations of the steps. In addition, the steps may be performed in a sequence different from a sequence presented in the embodiments of this application, and it is possible that not all the steps in the embodiments of this application need to be performed. 
       FIG. 3A  and  FIG. 3B  show an information processing method according to an embodiment of this application. The information processing method includes step  301  to step  316 . 
     Step  301 : A first terminal device detects that a battery level of the first terminal device is less than or equal to a first threshold. 
     The first terminal device may be the terminal device  103 , the terminal device  104 , or the terminal device  105  in the information processing system shown in  FIG. 1 . 
     Optionally, an intelligent application is installed on the first terminal device. The intelligent application is an application that performs the information processing method provided in this embodiment of this application. For example, the intelligent application performs all or some of step  301  to step  316 . 
     It should be noted that, when a user starts the intelligent application for the first time, the intelligent application may prompt the user about data (for example, a user account, permission for reading an application on the first terminal device, a geographical location of the first terminal device, and activity information of the application on the first terminal device) read by the intelligent application and a purpose of reading the data (for example, reading the user account is to query for an available device that uses the user account). 
     The available device may be an online device that uses the same user account as the first terminal device, and a battery level of the available device is greater than or equal to a second threshold. 
     Optionally, the first terminal device has a battery level detection capability. 
     For example, an application for detecting a battery level of a device may be installed on the first terminal device, and the application may periodically invoke a battery level detection interface of a system on the first terminal device. If the application detects that the battery level of the first terminal device is less than or equal to the first threshold, the application notifies the intelligent application. If the application detects that the battery level of the first terminal device is greater than the first threshold, the application does not notify the intelligent application, but continues periodically invoking the battery level detection interface of the system on the first terminal device. 
     For another example, the intelligent application may periodically invoke the battery level detection interface of the system on the first terminal device, to detect whether the battery level of the first terminal device is less than or equal to the first threshold. If the intelligent application detects that the battery level of the first terminal device is less than or equal to the first threshold, the intelligent application performs all or some of step  302  to step  316 . If the intelligent application detects that the battery level of the first terminal device is greater than the first threshold, the intelligent application does not perform the following steps, but continues periodically invoking the battery level detection interface of the system on the first terminal device. 
     Step  302 : Display second prompt information in a user interface of the first terminal device. 
     The second prompt information may be used to prompt the user to push an information list to another terminal device. 
     If the first terminal device is the terminal device  103  shown in  FIG. 1 , the another terminal device may be the terminal device  104  or the terminal device  105  shown in the figure. If the first terminal device is the terminal device  104  shown in  FIG. 1 , the another terminal device may be the terminal device  103  or the terminal device  105  shown in the figure. If the first terminal device is the terminal device  105  shown in  FIG. 1 , the another terminal device may be the terminal device  103  or the terminal device  104  shown in the figure. 
     The information list may include the activity information of the application on the first terminal device, for example, activity information of a conference application (for example, to hold a video conference at a place A at 2:00 p.m.), activity information in Note (for example, to buy a train ticket at 4:00 p.m.), and activity information of an alarm application (for example, to ring at 1:30 p.m.), activity information of a smart home application (for example, to turn on an air conditioner at 6:00 p.m.), activity information of an ebook application (for example, an ebook being read), and activity information of another application (for example, an electronic voucher in a ticket-buying application). 
     It should be noted that the available device may be a device on which the application (for example, Smart Home or Meituan) on the first terminal device is not installed; the available device may be a device on which some applications on the first terminal device are installed; or the available device may be a device on which all applications on the first terminal device are installed. 
       FIG. 4A  is a schematic diagram of a user interface of a first terminal device. When the first terminal device detects that the battery level of the first terminal device is less than or equal to 5%, the first terminal device may display, in the user interface of the first terminal device, the second prompt information shown in  FIG. 4A . A prompt dialog box  401  in  FIG. 4A  is used to prompt the user: This device has a low battery level. Whether to automatically push activity information of the application on this device to another available device. 
     Step  303 : The first terminal device receives a second acknowledgment message from the user. 
     The second acknowledgment message may be used to indicate the first terminal device to obtain the information list. 
     It should be noted that the second acknowledgment message is used to indicate the first terminal device to obtain the information list. This may be described as: The second acknowledgment message is used to indicate the first terminal device to perform step  304  and all or some of steps after step  304 . 
     For example, in  FIG. 4B , if the user taps (for example, taps one time) a cancel button, the first terminal device may return to a user interface  403 , and does not obtain the information list. 
     For example, if the user taps an OK button (in other words, the first terminal device receives the second acknowledgment message from the user), the first terminal device may automatically start an intelligent application  402 . For example, in  FIG. 4C , if the user taps an OK button, the first terminal device may display a startup interface  404  of the intelligent application. After the first terminal device starts the intelligent application  402 , the first terminal device performs all or some of step  304  to step  316 . 
     For example, if the user performs no operation within second preset time (to be specific, the user neither taps the cancel button in  FIG. 4A , nor taps the OK button in  FIG. 4A ), the first terminal device determines by default that the user taps the OK button. For example, if the user performs no operation within the second preset time (for example, 10 seconds (s)), the first terminal device may automatically start the intelligent application  402 ; and after the first terminal device starts the intelligent application  402 , the first terminal device performs all or some of step  304  to step  316 . 
     Step  304 : The first terminal device obtains activity information of N applications on the first terminal device. 
     The N applications may be all applications on the first terminal device; the N applications may be N frequently-used applications; or the N applications may be N user-defined applications. 
     For example, the first terminal device may obtain activity information of all the applications on the first terminal device. 
     For example, the first terminal device may obtain activity information of 10 frequently-used applications on the first terminal device. 
     For example, the user may customize eight applications in the intelligent application, and the first terminal device may subsequently obtain activity information of the eight applications. 
     The activity information of the N applications includes activity locations, activity time, and activity content, and N is a positive integer. 
     For example, the user defines six applications (a conference application, Note, Alarms, Smart Home, Ebook, and Meituan). Table 1 shows activity information of the six applications. For the conference application, activity content is to hold a video conference, activity time is 2:00 p.m., and an activity location is A. For Note, activity content is to buy a train ticket, activity time is 7:00 p.m., and an activity location is empty (that is, there are no special requirement on the activity location). For Alarms, activity content is that a lunch break is over, and activity time is 1:30 p.m. and an activity location is empty. For Smart Home, activity content is to turn on an air conditioner, activity time is 8 p.m., and an activity location is empty. For Ebook, activity content is Dream of Red Mansions.txt, activity time is now, and an activity location is empty (that is, the user is reading the ebook Dream of Red Mansions). For Meituan, activity content is a ticket code and/or a QR code for a movie, activity time is 4:00 p.m., and an activity location is B.

     Step  305 : The first terminal device selects, from the activity information of the N applications, activity information including activity time that is within first preset time and an activity location that has a distance to the geographical location of the first terminal device less than or equal to a third threshold. 
     The following describes step  305  by using the activity information of the six applications shown in Table 1 as an example. 
     It is assumed that current time is 1:00 p.m., the first preset time is three hours, the distance between the activity location A and the geographical location of the first terminal device is greater than the third threshold (for example, 20 kilometers), and the distance between the activity location B and the geographical location of the first terminal device is less than the third threshold. For the conference application, because the distance between the activity location A and the geographical location of the first terminal device is greater than the third threshold, the first terminal device does not select activity information of the conference application. For Note, because the activity time is not within the first preset time, the first terminal device does not select activity information of Note. For Alarms, because the activity time is within the first preset time, and there is no requirement on the activity location, the first terminal device selects activity information of Alarms. For Smart Home, because the activity time is not within the first preset time, the first terminal device does not select activity information of Smart Home. For Ebook, because the activity time is within the first preset time, and there is no requirement on the activity location, the first terminal device selects activity information of Ebook. For Meituan, because the activity time is within the first preset time, and the distance between the activity location B and the geographical location of the first terminal device is less than the third threshold, the first terminal device selects activity information of Meituan. 
     After step  305 , the activity information of the applications selected by the first terminal device is shown in Table 2.

     Step  306 : Display first prompt information in the user interface of the first terminal device. 
     The first prompt information may be used to prompt the user about the activity information selected by the first terminal device. 
     The activity information selected by the first terminal device may be displayed in the user interface of the first terminal device in a plurality of forms, for example, in a form of a picture or a form of a notification message. This is not limited. This application provides descriptions merely by using an example in which the activity information selected by the first terminal device is displayed in the user interface of the first terminal device in the form of a notification message. 
     It should be noted that if the first terminal device selects a plurality of pieces of activity information, and cannot display all the activity information selected by the first terminal device in the user interface of the first terminal device, a drop-down list may be added to the first terminal device, and the user may drag the drop-down list to view all the activity information selected by the first terminal device. 
     If the activity information selected by the first terminal device is shown in Table 2, the first terminal device may display the activity information shown in Table 2 in the user interface of the first terminal device, so that the user determines which activity information is to be pushed to the another terminal device. 
       FIG. 5  is a schematic diagram of a user interface of a first terminal device. In  FIG. 5 , prompt dialog boxes for the three pieces of activity information: a prompt dialog box  501  for the activity information of Alarms, a prompt dialog box  502  for the activity information of Ebook, and a prompt dialog box  503  for the activity information of Meituan, are displayed in the user interface  504  of the first terminal device. There is a check box in the lower right corner of each of the prompt dialog box  501  to the prompt dialog box  503 , and the check box may be used for the user to select whether to push activity information in a prompt dialog box in which the check box is located to the another terminal device. For example, if the user selects the prompt dialog box  501  and the prompt dialog box  502 , the user determines to push the activity information in the prompt dialog box  501  and the prompt dialog box  502  to the another terminal device. The user may tap a prompt dialog box or tap an icon for viewing details in the upper right corner of the prompt dialog box, to view detailed activity information in the prompt dialog box. For example, the user may tap the prompt dialog box  502 , to open the ebook Dream of Red Mansions, and may tap an icon  506  in the upper right corner of the prompt dialog box  501 , to view the detailed activity information of Alarms, and to modify a ringing moment and frequency of the alarm. 
     A prompt dialog box  504  is further displayed in the user interface  504  of the first terminal device in  FIG. 5 . The prompt dialog box  504  is used for the user to determine whether to push activity information in a prompt dialog box in which a check box is selected in the user interface  504  to the another terminal device. 
     It should be noted that  FIG. 5  merely shows an example of the first prompt information, and the first prompt information may alternatively be displayed in the user interface of the first terminal device in another form. This is not limited. 
     Step  307 : The first terminal device receives first acknowledgment information from the user. 
     The first acknowledgment information may include the information list. 
     For example, if the user selects the prompt dialog box  501  and the prompt dialog box  503  shown in  FIG. 5 , and taps an OK button in the prompt dialog box  504  (in other words, the first terminal device receives the first acknowledgment information from the user), the information list received by the first terminal device includes the activity information of Alarms and the activity information of Meituan. Subsequently, the first terminal device may push the information list to the another terminal device. 
     For example, if the user taps a cancel button in the prompt dialog box  504 , the first terminal device may not push the information list to the another terminal device. 
     For example, if the user performs no operation within third preset time, the first terminal device pushes by default all the activity information selected by the first terminal device to the another terminal device. For example, in the user interface  505  shown in  FIG. 5 , if the user performs no operation within the third preset time (for example, 8 s), the first terminal device determines by default that the user selects the prompt dialog box  501  to the prompt dialog box  503  and taps the OK button. 
     Step  308 : The first terminal device sends query information to an account server. 
     The query information may be used to query for an available device. 
     Optionally, the query information includes the user account used by the first terminal device. After receiving the query information, the account server queries for, based on the user account included in the query information and used by the first terminal device, an available device that uses the user account. 
     Optionally, the query information includes an identifier of the first terminal device. After receiving the query information, the account server queries for, based on the identifier of the first terminal device included in the query information, the user account used by the first terminal device, and then queries for, based on the user account used by the first terminal device, an available device that uses the user account. 
     Optionally, the query information includes the user account used by the first terminal device and an identifier of the first terminal device. After receiving the query information, the account server queries for, based on the user account used by the first terminal device or the identifier of the first terminal device, an available device that uses under the user account used by the first terminal device. 
     Step  309 : The account server receives the query information sent by the first terminal device, and sends query response information to the first terminal device. 
     The query response information may include a device list, and the device list may include information about the available device. 
     It should be noted that the device list may be in a plurality of forms, for example, a table or an array. This is not limited. This application provides descriptions merely by using an example in which the device list is in the form of a table. 
     In a case, the information about the available device includes an identifier of the available device and a battery level of the available device. 
     For example, the first terminal device is the terminal device  103  in  FIG. 1 , and the available devices are the terminal device  104  and the terminal device  105  in  FIG. 1 . The device list may be shown in Table 3. In Table 3, for the terminal device  104 , an identifier is 1, and a battery level is 80%; and for the terminal device  105 , an identifier is 2, and a battery level is 75%.

     It should be noted that Table 3 merely shows an example of the device list. In actual application, the device list may include any row of information in Table 3, or the device list may include information about more available devices than the available devices shown in Table 3. This is not limited. 
     In another case, the information about the available device includes an identifier of the available device, a battery level of the available device, and a geographical location of the available device. 
     For example, the first terminal device is the terminal device  103  in  FIG. 1 , and the available devices are the terminal device  104  and the terminal device  105  in  FIG. 1 . The device list may be shown in Table 4. In Table 4, for the terminal device  104 , an identifier is 1, a battery level is 80%, and a geographical location is C; and for the terminal device  105 , an identifier is 2, a battery level is 75%, and a geographical location is D.

     It should be noted that Table 5 merely shows an example of the device list. In actual application, the device list may include any row of information in Table 5, or the device list may include information about more available devices than the available devices shown in Table 5. This is not limited. 
     Step  310 : The first terminal device receives the query response information sent by the account server, and determines a second terminal device based on the query response information. 
     The second terminal device may be a terminal device selected from the available device. 
     In a case, if the device list includes information about one available device, and a battery level of the available device is greater than or equal to the second threshold, that the first terminal device determines a second terminal device based on the query response information may include: The first terminal device determines that the available device is the second terminal device. 
     For example, the device list includes information about one available device, and the second threshold is 50%. If a battery level of the available device is 80%, the first terminal device determines that the available device is the second terminal device. 
     In another case, if the device list includes information about two or more available devices, that the first terminal device determines a second terminal device based on the query response information may include: The first terminal device determines the second terminal device based on geographical locations of the two or more available devices and/or battery levels of the two or more available devices. 
     The information about the available devices shown in Table 4 is used as an example for description below. 
     In Example 1, the first terminal device determines, from the two or more available devices, that an available device whose geographical location is nearer/nearest to the first terminal device is the second terminal device. For example, if a distance between the geographical location of the first terminal device and the geographical location C of the terminal device  104  is less than a distance between the geographical location of the first terminal device and the geographical location D of the terminal device  105 , the first terminal device determines that the terminal device  104  is the second terminal device. 
     In Example 2, the first terminal device determines, from the two or more available devices, that an available device with a higher/highest battery level is the second terminal device. 
     For example, if the battery level (80%) of the terminal device  104  is higher than the battery level (75%) of the terminal device  105 , the first terminal device determines that the terminal device  104  is the second terminal device. 
     In Example 3, the first terminal device determines, from the two or more available devices, that an available device whose geographical location is nearer/nearest to the first terminal device and whose battery level is higher/highest is the second terminal device. For example, if a distance between the geographical location of the first terminal device and the geographical location C of the terminal device  104  is less than a distance between the geographical location of the first terminal device and the geographical location D of the terminal device  105 , and the battery level (80%) of the terminal device  104  is higher than the battery level (75%) of the terminal device  105 , the first terminal device determines that the terminal device  104  is the second terminal device. 
     In still another case, if the device list includes information about two or more available devices, that the first terminal device determines a second terminal device based on the query response information may include: The first terminal device determines priorities of the available devices based on geographical locations of the two or more available devices and/or battery levels of the two or more available devices, and displays third prompt information in the user interface of the first terminal device. The first terminal device receives a third acknowledgment message from the user, and determines the second terminal device based on the third acknowledgment message. 
     The third prompt information may be used to prompt the user to select the second terminal device. The third acknowledgment message is used to indicate the second terminal device. 
     The information about the available devices shown in Table 5 is used as an example for description below. 
     In Example 4, the first terminal device determines, from the two or more available devices, that a priority of an available device whose geographical location is nearer/nearest to the first terminal device is higher than a priority of an available device whose geographical location is further/furthest from the first terminal device. For example, if a distance between the geographical location of the first terminal device and the geographical location C of the terminal device  104  is less than a distance between the geographical location of the first terminal device and the geographical location D of the terminal device  105 , the first terminal device determines that a priority of the terminal device  104  is higher than a priority of the terminal device  105 . 
     In Example 5, the first terminal device determines, from the two or more available devices, that a priority of an available device with a higher/highest battery level is higher than a priority of an available device with a lower/lowest battery level. For example, if the battery level (80%) of the terminal device  104  is higher than the battery level (75%) of the terminal device  105 , the first terminal device determines that a priority of the terminal device  104  is higher than a priority of the terminal device  105 . 
     In Example 6, the first terminal device determines, from the two or more available devices, that a priority of an available device whose geographical location is nearer/nearest to the first terminal device and whose battery level is higher/highest is higher than a priority of an available device whose geographical location is further/furthest from the first terminal device and whose battery level is lower/lowest. For example, if a distance between the geographical location of the first terminal device and the geographical location C of the terminal device  104  is less than a distance between the geographical location of the first terminal device and the geographical location D of the terminal device  105 , and the battery level (80%) of the terminal device  104  is higher than the battery level (75%) of the terminal device  105 , the first terminal device determines that a priority of the terminal device  104  is higher than a priority of the terminal device  105 . 
       FIG. 6  is a schematic diagram of a user interface of a first terminal device. In  FIG. 6 , a prompt dialog box  602  is displayed in the user interface  601 . The prompt dialog box  602  is used to prompt the user to select the second terminal device. Available devices (GT and P20pro) displayed in the prompt dialog box  602  are user equipments sorted in descending order based on priorities of the available devices determined in the foregoing Example 4 to Example 6 (that is, a priority of GT is higher than a priority of P20pro), and the first terminal device selects an available device with a higher/highest priority as the second terminal device by default. The user may select a proper available device as required and tap an OK button. 
     For example, if the terminal device  104  is located besides the user, the user may directly tap the OK button. In this case, the first terminal device uses the terminal device  104  as the second terminal device. 
     For example, if the terminal device  105  is located besides the user, the user may select P20pro, and then tap the OK button. In this case, the first terminal device uses the terminal device  105  as the second terminal device. 
     For example, the user equipment may tap a cancel button to cancel pushing of the information list or to indicate the account server to query for an available device again. 
     For example, if the user performs no operation within fourth preset time, the first terminal device determines by default that an available device with a higher/highest priority is the second terminal device. For example, if the user performs no operation within the fourth preset time (for example, 9 s), the first terminal device uses the terminal device  104  as the second terminal device. 
     Optionally, if the account server does not find an available device, the query response information does not include information about an available device. In this case, after receiving the query response information, the first terminal device prompts the user with “There is no available device. Please check whether another device has logged in or has a low battery level”. 
     Step  311 : The first terminal device sends first information to the account server. 
     The first information may include the information list and an identifier of the second terminal device, and the first information may be used to indicate the account server to send second information to a message push server. 
     Step  312 : The account server receives the first information sent by the first terminal device, and sends the second information to the message push server. 
     The second information may include the identifier of the second terminal device, and the second information may be used to indicate the message push server to send third information to the second terminal device. 
     Optionally, after receiving the first information, the account server sends response information of the first information to the first terminal device, where the response information of the first information is used to indicate that the account server successfully receives the first information. 
     Optionally, if the first terminal device does not receive the response information of the first information within fifth preset time, the first terminal device re-sends the first information to the account server. 
     For example, after sending the first information to the account server, the first terminal device does not receive the response information of the first information within the fifth preset time (for example, 20 s). In this case, the first terminal device re-sends the first information to the account server. 
     Step  313 : The message push server receives the second information sent by the account server, and sends the third information to the second terminal device. 
     The third information may be used to indicate the second terminal device to obtain the information list from the account server. 
     Optionally, after receiving the second information sent by the account server, the message push server sends response information of the second information to the account server. The response information of the second information is used to indicate that the message push server successfully receives the second information. 
     Optionally, if the account server does not receive the response information of the second information within sixth preset time, the account server re-sends the second information to the account server. 
     For example, after sending the second information to the message push server, the account server does not receive the response information of the second information within the sixth preset time (for example, 15 s). In this case, the account server re-sends the second information to the message push server. 
     Step  314 : The second terminal device receives the third information sent by the message push server, and sends information for obtaining the information list to the account server. 
     The information for obtaining the information list may be used to obtain the information list from the account server. The information for obtaining the information list may include the identifier of the second terminal device. 
     Optionally, the second terminal device receives the third information sent by the message push server, and displays fourth prompt information in a user interface of the second terminal device; the second terminal device receives fourth acknowledgment information sent by the user; and the second terminal device sends the information for obtaining the information list to the account server. 
     The fourth prompt information may be used to notify the user that another device needs to push an information list to the second terminal device. The fourth acknowledgment information may be used to indicate the second terminal device to obtain the information list. 
       FIG. 7  is a schematic diagram of a user interface of a second terminal device. In  FIG. 7 , prompt information displayed in the user interface  701  is whether to receive activity information of an application pushed by another device. 
     If the user taps a cancel button, the second terminal device does not receive the activity information of the application pushed by the another device. 
     If the user clicks an OK button (in other words, the second terminal device receives the fourth acknowledgment information sent by the user), the second terminal device sends the information for obtaining the information list to the account server. 
     If the user performs no operation within seventh preset time, the second terminal device determines by default that the user taps the OK button, and the second terminal device sends the information list obtaining information to the account server. For example, if the user performs no operation within the seventh preset time (for example, 5 s), the second terminal device sends the information for obtaining the information list to the account server. 
     Step  315 : The account server receives the information that is used for obtaining the information list and that is sent by the second terminal device, and sends the information list corresponding to the identifier of the second terminal device to the second terminal device. 
     Optionally, the account server receives the information that is used for obtaining the information list and that is sent by the second terminal device, obtains, based on the identifier of the second terminal device included in the information for obtaining the information list, the information list corresponding to the identifier of the second terminal device, and then sends the information list corresponding to the identifier of the second terminal device to the second terminal device. 
     Step  316 : The second terminal device receives the information list that corresponds to the identifier of the second terminal device and that is sent by the account server. 
     Optionally, the second terminal device receives the information list that corresponds to the identifier of the second terminal device and that is sent by the account server, and displays the information list in the user interface of the second terminal device. 
       FIG. 8  is a schematic diagram of a user interface of a second terminal device. In  FIG. 8 , for example, the second terminal device displays the information list shown in  FIG. 5  in the user interface  801 , and prompt dialog boxes for three pieces of activity information are displayed in the user interface  801 : a prompt dialog box  802  for the activity information of Alarms, a prompt dialog box  803  for the activity information of Ebook, and a prompt dialog box  804  for the activity information of Meituan. There is a check box in the lower right corner of each of the prompt dialog box  802  and the prompt dialog box  804 , and the check box may be used for the user to select whether to continue to prompt activity information in a prompt dialog box in which the check box is located. The user may tap a prompt dialog box or tap an icon for viewing details in the upper right corner of the prompt dialog box, to view detailed activity information in the prompt dialog box. For example, the user may tap the prompt dialog box  803 , to open the ebook Dream of Red Mansions, and may tap an icon  805  in the upper right corner of the prompt dialog box  802 , to view the detailed activity information of Alarms, and to modify a ringing moment and frequency of the alarm. 
     For example, it is assumed that the user selects the prompt dialog box  804 , but does not select the prompt dialog box  802  and the prompt dialog box  803 , and taps an OK button in the user interface  801 . Subsequently, the second terminal device prompts the activity information of Meituan before 4:00 p.m. (for example, at 3:30 p.m.). However, the second terminal device does not prompt the activity information of Alarms and the activity information of Ebook. Subsequently, if the user further wants to read the ebook Dream of Red Mansions, the user may open the ebook in a storage device of the first terminal device. 
     For example, if the user taps a cancel button in the user interface  801 , subsequently, the second terminal device does not prompt the activity information of Alarms, the activity information of Ebook, or the activity information of Meituan. 
     For example, if the user performs no operation within eighth preset time, the second terminal device determines by default that the user selects the prompt dialog box  802  to the prompt dialog box  804  and taps the OK button in the user interface  801 . Subsequently, the second terminal device opens the ebook Dream of Red Mansions to a location to which the user has read on the first terminal device, prompts the activity information of Alarms at 13:30, and prompts the activity information of Meituan before 4:00 p.m. (for example, at 3:30 p.m.). 
     Optionally, the second terminal device receives the information list that corresponds to the identifier of the second terminal device and that is sent by the account server, and prompts the user about the activity information before the activity time. 
     The following provides descriptions by using an example in which the information list corresponding to the identifier of the second terminal device includes the activity information shown in Table 2. 
     For example, the second terminal device receives the information list that corresponds to the identifier of the second terminal device and that is sent by the account server. The second terminal device opens the ebook Dream of Red Mansions to a location to which the user has read on the first terminal device, prompts the activity information of Alarms at 13:30, and prompts the activity information of Meituan before 4:00 p.m. (for example, at 3:30 p.m.). 
     It should be noted that if the first terminal device has established a Bluetooth connection to the second terminal device, the first terminal device may alternatively not perform step  311  to step  316 , and the first terminal device may push the information list corresponding to the identifier of the second terminal device to the second terminal device through Bluetooth. 
     Optionally, the second terminal device receives, through Bluetooth, the information list that corresponds to the identifier of the second terminal device and that is sent by the first terminal device, and displays the information list in the user interface of the second terminal device. 
     For a specific process in which the second terminal device displays the information list in the user interface of the second terminal device, refer to corresponding descriptions in step  316 . Details are not described herein again. 
     Optionally, the second terminal device receives, through Bluetooth, the information list that corresponds to the identifier of the second terminal device and that is sent by the first terminal device, and prompts the user about the activity information before the activity time. 
     For a specific process in which the second terminal device prompts the user about the activity information before the activity time, refer to corresponding descriptions in step  316 . Details are not described herein again. 
     Based on the method shown in  FIG. 3A  and  FIG. 3B , when detecting that the battery level of the first terminal device is less than or equal to the first threshold, the first terminal device may obtain the activity information of the application on the first terminal device, and push the activity information of the application to the second terminal device, where the second terminal device is the terminal device selected from the available device, the available device is the online device that uses the same user account as the first terminal device, and the battery level of the available device is greater than or equal to the second threshold. This can resolve a problem that the activity information of the application on the first terminal device cannot be obtained when the first terminal device runs out of power. 
     The method shown in  FIG. 3A  and  FIG. 3B  is a detailed process of the information processing method. An embodiment of this application further provides an information processing method. As shown in  FIG. 9 , the information processing method includes step  901  to step  903 .

The first terminal device selects, from the activity information of the N applications, activity information including activity time that is within first preset time and an activity location that has a distance to a geographical location of the first terminal device less than or equal to a third threshold. The first terminal device obtains the information list based on the selected activity information. 
     For a specific process in the first implementation scenario in this embodiment shown in  FIG. 9 , refer to the descriptions in step  304  and step  305  in the method shown in  FIG. 3A  and  FIG. 3B . 
     Based on the first implementation scenario in this embodiment shown in  FIG. 9 , the first terminal device may obtain the activity information of the N applications on the first terminal device, select, from the activity information of the N applications, the activity information including the activity time that is within the first preset time and the activity location that has the distance to the geographical location of the first terminal device less than or equal to the third threshold, and obtain the information list based on the selected activity information.

     For a specific process in the second implementation scenario in this embodiment shown in  FIG. 9 , refer to the descriptions in step  306  and step  307  in the method shown in  FIG. 3A  and  FIG. 3B . 
     Based on the second implementation scenario in this embodiment shown in  FIG. 9 , the first terminal device may display, in the user interface of the first terminal device, the activity information selected by the first terminal device. The activity information autonomously selected by the user may be included in the information list. 
     Optionally, in a third implementation scenario in this embodiment shown in  FIG. 9 , before the first terminal device obtains the information list, the method shown in  FIG. 9  further includes: The first terminal device displays second prompt information in the user interface of the first terminal device, where the second prompt information is used to prompt the user to push the information list to another terminal device. The first terminal device receives a second acknowledgment message from the user, where the second acknowledgment message is used to indicate the first terminal device to obtain the information list.

Whether to automatically push activity information of the application on this device to another available device”, and determine, based on a selection of the user, whether to enable an intelligent application. 
     Optionally, in the fourth implementation scenario in this embodiment shown in  FIG. 9 , that the first terminal device determines a second terminal device includes: The first terminal device sends query information to an account server, where the query information is used to query for an available device. The first terminal device receives query response information sent by the account server, where the query response information includes a device list, and the device list includes information about the available device. The first terminal device determines the second terminal device based on the query response information. 
     For a specific process in the fourth implementation scenario in this embodiment shown in  FIG. 9 , refer to the descriptions in step  308  to step  310  in the method shown in  FIG. 3A  and  FIG. 3B . 
     Based on the fourth implementation scenario in this embodiment shown in  FIG. 9 , the first terminal device may send the query information to the account server, and determine the second terminal device based on the received query response information sent by the account server. 
     Optionally, in the fifth implementation scenario in this embodiment shown in  FIG. 9 , That the first terminal device pushes an information list to the second terminal device includes: The first terminal device sends first information to the account server, where the first information includes the information list, the first information is used to indicate the account server to send second information to a message push server, the second information is used to indicate the message push server to send third information to the second terminal device, and the third information is used to indicate the second terminal device to obtain the information list from the account server; and the account server is configured to manage terminal devices that use the same user account, and the message push server is configured to push a message to a terminal device. 
     For a specific process in the fifth implementation scenario in this embodiment shown in  FIG. 9 , refer to the descriptions in step  311  to step  316  in the method shown in  FIG. 3A  and  FIG. 3B .

     In the methods shown in  FIG. 3A  and  FIG. 3B  and  FIG. 9 , when detecting that the battery level of the first terminal device is less than or equal to the first threshold, the first terminal device starts the intelligent application, obtains the information list, determines the second terminal device, and then pushes the information list to the second terminal device. Alternatively, when detecting that the battery level of the first terminal device is less than or equal to the first threshold, the first terminal device may first determine whether there is an available device without starting a user interface of the intelligent application. 
     An embodiment of this application further provides an information processing method. As shown in  FIG. 10A  and  FIG. 10B , the information processing method includes step  1001  to step  1016 . 
     Step  1001 : A first terminal device detects that a battery level of the first terminal device is less than or equal to a first threshold. 
     For a specific process of step  1001 , refer to the descriptions in step  301 . Details are not described herein again. 
     Step  1002 : The first terminal device sends query information to an account server. 
     Step  1003 : The account server receives the query information sent by the first terminal device, and sends query response information to the first terminal device. 
     For specific processes of step  1002  and step  1003 , refer to the descriptions in step  308  and step  309 . Details are not described herein again. 
     It should be noted that step  1002  and step  1003  may be performed when the first terminal device does not start a user interface of an intelligent application. For example, when the first terminal device detects that the battery level of the first terminal device is less than or equal to the first threshold, the first terminal device performs step  1002  and step  1003  in background. 
     Optionally, if the query response information includes information about an available device, the first terminal device starts the user interface of the intelligent application, and performs all or some of step  1004  to step  1016 . 
     Optionally, if the query response information does not include information about an available device, the first terminal device does not start the user interface of the intelligent application, or the first terminal device starts the user interface of the intelligent application and prompts a user with “There is no available device. Please check whether another device has logged in or has a low battery level”. 
     Step  1004 : Display second prompt information in a user interface of the first terminal device. 
     Step  1005 : The first terminal device receives a second acknowledgment message from the user. 
     Step  1006 : The first terminal device obtains activity information of N applications on the first terminal device. 
     Step  1007 : The first terminal device selects, from the activity information of the N applications, activity information including activity time that is within first preset time and an activity location that has a distance to the geographical location of the first terminal device less than or equal to a third threshold. 
     Step  1008 : Display first prompt information in the user interface of the first terminal device. 
     Step  1009 : The first terminal device receives first acknowledgment information from the user. 
     For specific processes of step  1004  to step  1009 , refer to the descriptions in step  302  to step  307 . Details are not described herein again. 
     Step  1010 : The first terminal device receives the query response information sent by the account server, and determines a second terminal device based on the query response information. 
     Step  1011 : The first terminal device sends first information to the account server. 
     Step  1012 : The account server receives the first information sent by the first terminal device, and sends second information to a message push server. 
     Step  1013 : The message push server receives the second information sent by the account server, and sends third information to the second terminal device. 
     Step  1014 : The second terminal device receives the third information sent by the message push server, and sends information for obtaining an information list to the account server. 
     Step  1015 : The account server receives the information that is used for obtaining the information list and that is sent by the second terminal device, and sends the information list corresponding to an identifier of the second terminal device to the second terminal device. 
     Step  1016 : The second terminal device receives the information list that corresponds to the identifier of the second terminal device and that is sent by the account server. 
     For specific processes of step  1010  to step  1016 , refer to the descriptions in step  310  to step  316 . Details are not described herein again. 
     Based on the method shown in  FIG. 10A  and  FIG. 10B , when detecting that the battery level of the first terminal device is less than or equal to the first threshold, the first terminal device may first query whether there is an available device; and if there is an available device, the first terminal device obtains activity information of an application on the first terminal device, and pushes the activity information of the application to the second terminal device, where the second terminal device is a terminal device selected from the available device, the available device is an online device that uses a same user account as the first terminal device, and a battery level of the available device is greater than or equal to a second threshold. This can resolve a problem that the activity information of the application on the first terminal device cannot be obtained when the first terminal device runs out of power.
