[0078] In the first embodiment, the battery power failure detection method includes the following steps:

[0079] Step S10, calculating the total power consumption of the system application in each preset node segment;

[0080] During the use of the mobile terminal, the mobile terminal may lose power too quickly. This situation may be caused by the abnormal power consumption of the system application of the mobile terminal, or it may be caused by abnormal battery reasons such as battery swelling and aging. In the prior art, it usually only detects whether there is abnormal power consumption of the application, and ignores the detection of the abnormal condition of the battery. Therefore, the battery power-down detection method of the present invention is proposed. In this battery power-down detection method, the power-down process of the mobile terminal battery is divided into multiple node segments in advance, for example, the power-down process of the battery is set to a plu...

Abstract

The invention discloses a battery power-down detection method. In the battery power-down detection method, the total power consumption of system applications in each preset node segment is calculated; according to the total power consumption of system applications, Calculate the unit percentage power consumption of the system application in each preset node segment, and calculate the power-down speed of the battery in each preset node segment; when detecting that there is at least one preset node segment When the charging speed is greater than the preset power-down speed threshold, and the unit percentage power consumption is smaller than the preset unit percentage power consumption threshold, it is determined that the battery power-down is abnormal. The invention also discloses a battery power failure detection device and a mobile terminal. The invention realizes the accurate detection of the reason why the mobile terminal loses power too quickly.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a battery power-down detection method, device and mobile terminal. Background technique [0002] With the development of science and technology, people's lives are inseparable from various mobile terminals. During the use of mobile terminals, excessive power loss may occur, causing inconvenience to users. In the prior art, when the mobile terminal experiences an abnormal situation of excessive power loss, it usually only detects whether there is an abnormal power consumption of the system application, and ignores the abnormal cause of the battery such as battery expansion and aging, which causes the excessive power loss. The reason why the terminal powers off too quickly. Contents of the invention [0003] The main purpose of the present invention is to provide a battery power-down detection method, device and mobile terminal, aiming at solving the existing technical probl...
