Abstract

The invention is applicable to the communication field and provides a method and a device for switching central processing unit (CPU) working modes according to application scenarios. The method includes detecting a current application scenario of a terminal; switching to a corresponding CPU working mode according to the detected application scenario and a preset mapping table of the application scenarios and the CPU working modes. By means of the method and the device, power consumption of the terminal can be reduced, and the cruising ability of batteries is improved.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a method and a device for switching CPU working modes according to application scenarios. Background technique [0002] Battery life has become a major concern for smartphones. Nowadays, the pursuit of thinness and lightness in the structural design of smartphones makes it impossible to make the battery capacity of the device large. So how to optimize the power consumption of the system, provide the endurance of the system, and give users a good experience has become a major issue when the battery power is constant. There are many factors that affect system power consumption, including the display screen and CPU. Taking the CPU as an example, the CPU working modes generally include Interactive3, Ondemand2, Userspace4, Powersave5, Performance1, etc. Different CPU working modes have different impacts on system power consumption. In other words, the low-power mode will have a...
