Problems solved by technology

[0003] At present, some applications that have not been strictly reviewed may be installed in the terminal. When these applications are running in the background, they occupy a large amount of CPU (Central Processing Unit, central processing unit) resources, and even cause the terminal to heat up. In the prior art, when When the temperature of the terminal exceeds the preset temperature, it will limit the heat generation of related original devices until the temperature drops to the estimated temperature, and release the restrictions on related original devices, such as CPU and GPU, etc.
[0004] However, in the solution adopted in the prior art, when the temperature of the terminal exceeds the preset temperature, the CPU or GPU frequency will be limited. At the same time, it cannot effectively solve the problem of temperature rise

Abstract

The invention discloses a method and a device of making a terminal generate less heat, a mobile terminal and a storage medium, relating to the technical field of mobile terminals. According to the method, first, a running power consumption value and a heat causing number of times of a first background process of a terminal are acquired; then whether the heat causing number of times is greater than a preset number of times is determined; and finally, if the heat causing number of times is greater than the preset number of times, the first background process is allowed to run on a small core of a CPU of the terminal, and the CPU frequency of the terminal is limited according to the running power consumption value. Through adoption of the method and device of making the terminal generate less heat, the mobile terminal and the storage medium, heat generated by the terminal and the impact on terminal performance are reduced by lowering the power consumption of the background process, further, power consumption of the terminal is lowered, and the battery endurance of the terminal is enhanced.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, and more specifically, to a method, device, mobile terminal and storage medium for reducing heat generation of a terminal. Background technique [0002] The so-called foreground process refers to the program that the user is operating, and the so-called background process refers to the program that is still running without the user operating. [0003] At present, some applications that have not been strictly reviewed may be installed in the terminal. When these applications are running in the background, they occupy a large amount of CPU (Central Processing Unit, central processing unit) resources, and even cause the terminal to heat up. In the prior art, when When the temperature of the terminal exceeds the preset temperature, it will limit the heating of related original devices, and release the restrictions on related original devices, such as CPU and GPU, until the temperatur...
