Method and device for clearing malicious power consumption applications, and user terminal

Abstract

An embodiment of the invention provides a method and a device for clearing malicious power consumption applications, and a user terminal. Background work power consumption of applications running in the user terminal is periodically counted, the applications with the background work power consumption not lower than a power consumption threshold value are determined as the malicious power consumption applications, wake lock holding time of each application running in the user terminal with a screen closed is periodically counted, if a certain application with the holding time not shorter than a set time threshold value is a background work application, the application is determined as a malicious power consumption application unreasonably occupying resources in background, the applications with high power consumption but normally used by a user are not malicious power consumption applications, the malicious power consumption applications can be accurately positioned and detected, unnecessary power consumption of the user terminal is avoided while usage experience of the user is ensured, electric energy is saved, and the battery life of the user terminal is prolonged to a certain degree.

Description

technical field [0001] The present invention relates to the field of user terminal equipment, in particular to a cleaning method, device and user terminal for malicious power-consuming applications. Background technique [0002] At present, many user terminals, especially smart terminals, due to the improvement of processing capabilities, larger and larger screens, higher and higher resolutions, and the network supports high-speed wireless networks such as WIFI, 3G, and LTE, there are generally power-hungry For example, the longest standby time of many smartphones or tablet computers is usually less than one day. For users, frequent charging is required to ensure normal use, which is very inconvenient. [0003] In addition, because smart terminals can support a variety of applications, some open application markets are flooded with bad applications. After users download and install these applications, they will unreasonably occupy the system resources of smart terminals, inc...

[0005] In this way, the applications included in the ranking may be applications that users really want to use and frequently use. For example, an application that users often use to watch online videos. It needs to be connected to the Internet and consumes a lot of network resources. When users watch videos, the screen brightness is often relatively high. For this kind of application, high power consumption is a natural situation. From another point of view, this ranking method in the prior art cannot accurately locate those bad applications that maliciously consume power, and it cannot well avoid the impact of these bad applications on the battery life of smart terminals.
