Method for prolonging service life of mobile terminal in low battery mode and mobile terminal

Abstract

The invention discloses a method for prolonging the service life of a mobile terminal in a low battery mode and the mobile terminal. The mobile terminal comprises a battery (2), a voltage detection module (6), a voltameter module (5) a CPU (4) and a display screen (3). The voltameter module (5) is used for detecting the power consumption electric current (I) and dump energy (Q) of the mobile terminal (1) in real time. The voltage detection module (6) is used for detecting the battery voltage in real time. The CPU (4) is used for changing the auto power-off voltage threshold value of the mobile terminal (1) when the dump energy (Q) is judged to be smaller than a preset electric quantity threshold value (Q0) and the power consumption electric current (I) is larger than a preset current threshold value (I0). The CUP (4) is also used for displaying prompt information that the mobile terminal is in low battery through the display screen (3) when the battery voltage value is judged to range between a second auto power-off voltage threshold value (V2) and a first auto power-off voltage threshold value (V1).

Description

technical field [0001] The present invention relates to a mobile terminal, more specifically, to a method for prolonging the use time of a mobile terminal under low battery power and a mobile terminal using the method. Background technique [0002] In the prior art, in order to avoid the forced shutdown of mobile terminals such as smart phones and tablet computers due to the exhaustion of battery power, the method adopted is usually to set an automatic shutdown voltage point of the mobile terminal. When the power management software detects that the battery voltage of the mobile terminal is lower than the default automatic shutdown voltage point of the system, the shutdown operation is initiated to avoid sudden shutdown that may occur when the user continues to use the mobile terminal. [0003] The disadvantage of this method is that: the decrease of the battery voltage of the mobile terminal is negatively correlated with the power consumption current of the mobile terminal....

Problems solved by technology

[0003] The defect of this method is that: since the decrease of the battery voltage of the mobile terminal is negatively correlated with the power consumption current of the mobile terminal

Therefore, when a user uses a mobile terminal with low battery power to run an application program with high power consumption, although the battery power of the mobile terminal is not exhausted, the actual voltage value of the battery of the mobile terminal is higher than the default automatic shutdown voltage point of the system. The battery voltage of the mobile terminal suddenly drops below the automatic shutdown voltage point, prompting the mobile terminal to start the shutdown program and automatically shut down, the battery of the mobile terminal is not fully utilized, and the battery life is shortened to a certain extent
