Method and terminal for switching application

The invention provides a method for switching application. The method includes receiving an information selection instruction of a user; displaying prompt of application according to the selection instruction; receiving a switching instruction of the user and switching the application to a foreground according to the switching instruction. The application has a preset corresponding relation with information corresponding to the selection instruction and runs on a background, and the switching instruction is used for switching the application to the foreground via the prompt. The method for switching the application has the advantages that the prompt of the application is displayed according to the selection instruction after a terminal receives the information selection instruction of the user, the application has the preset corresponding relation with the information and runs on the background, accordingly, the application is switched to the foreground according to the operation instruction after the operation instruction for switching the application to the foreground via the prompt is received from the user, the user can switch the application to the foreground without clicking multiple task keys to call out a task management interface, and the operation convenience can be improved. The invention further provides the terminal.

Control method and system of power consumption state of mobile terminal

A control method of the power consumption state of a mobile terminal comprises the following steps that state change of an application switch related to preset power saving modes of the mobile terminal is monitored; when it is monitored that state change exists, the current state of the application switch is acquired; a power saving mode matched with the current state of the application switch is searched for from the preset power saving modes; the current power consumption state of the mobile terminal is switched to the matched power saving mode, and a prompt is made for the current power saving mode of the mobile terminal. The overall power consumption state of the mobile terminal is prompted through the current power saving mode of the mobile terminal, once state change of the application switch exists, the power saving mode matched with the current state of the application switch can be automatically prompted, the overall power consumption state of the mobile terminal can be displayed automatically, rapidly and conveniently, and therefore operation convenience is improved and the power consumption amount of the mobile terminal is further saved. Besides, the invention further provides a control system of the power consumption state of the mobile terminal.
