Device and method for entering power-saving mode of hand-held terminal rapidly

Abstract

The invention relates to a device and a method for entering a power-saving mode of a hand-held terminal rapidly. The device comprises a central processing unit (CPU), a power-saving mode shortcut key, a power supply detection module and a hand-held terminal interface module. The method comprises the following steps of: judging whether the power-saving mode shortcut key is triggered or not by using the CPU; if so, entering the power-saving mode of the hand-held mode, and otherwise, judging whether the residual electric quantity is lower than a preset value or not; and if the residual electric quantity is lower than the preset value, entering power-saving mode of the hand-held mode. The power-saving mode shortcut key and the power supply detection module are adopted to enter the power-saving mode of the hand-held terminal rapidly, close unnecessary system services and application services, invoke a system interface, turn down the brightness of a screen, turn down the volume of the system and reduce the frequency of the CPU, so that the power consumption of the hand-held terminal can be reduced to a maximum degree and the standby time of hand-held terminal can be prolonged.

Description

technical field [0001] The present invention relates to a handheld terminal, in particular to a power saving device and method for the handheld terminal. Background technique [0002] The standby time of handheld terminals has always been a matter of great concern to users. At present, with the development of handheld terminals to multi-function, large capacity, and large display screens, the standby time is getting shorter and shorter. In order to ensure the standby time of handheld terminals, on the one hand, improve The capacity of the power supply of the handheld terminal, but due to the limitation of battery technology, the existing battery cannot meet the needs of users. On the other hand, it uses hardware control to save power or controls power consumption through application software. [0003] In order to prolong the standby time of the handheld terminal, the above-mentioned means need to rely on the user to close some power-consuming applications and services in the...
