Method and device for mobile terminal power management and mobile terminal

Abstract

The invention discloses a method for mobile terminal power management. The method comprises the steps of detecting a voltage difference between one side, which is connected to a charging chip and a main-board, of a switching circuit and the other side, which is connected to a battery anode, of the switching circuit when a battery is in the charge and discharge state; and judging the charging and discharging state of a mobile terminal power according to the detected voltage difference. Meanwhile the invention also discloses a device for mobile terminal power management and a mobile terminal.

Description

technical field [0001] The present invention relates to power detection technology, in particular to a mobile terminal power management method, device and mobile terminal. Background technique [0002] With the increase of various functions and hardware devices of the mobile terminal, such as providing entertainment functions such as Internet access and video playback, and increasing the screen of the mobile terminal, the power consumption of the mobile terminal will gradually increase. In this way, when people use the mobile terminal, they need to charge the mobile terminal anytime and anywhere, so as to maintain the normal operation of the mobile terminal. [0003] The equipment that can charge the mobile terminal now has fixed power supply, mobile power supply and equipment with USB interface. These equipment can charge the mobile terminal. Different charging equipment will provide different currents when charging the mobile terminal power supply; Convenient, most mobile...

Problems solved by technology

[0003] The equipment that can charge the mobile terminal now has fixed power supply, mobile power supply and equipment with USB interface. These equipment can charge the mobile terminal. Different charging equipment will provide different currents when charging the mobile terminal power supply; Convenient, most mobile terminals use the same line for charging and data, for some application functions provided by mobile terminals, such as: playing games and watching videos on a large screen, the current consumption of data transmission is often large; in this case , during the use of the mobile terminal, when it needs to be charged, the charging current may be smaller than the actual current consumption of the mobile terminal. In this way, the mobile terminal will consume power even when it is charging. If the power is greater than the charging power, the mobile terminal will automatically shut down after the power is exhausted

At this time, if the mobile terminal is charged, the mobile terminal will restart, but it will shut down again because the input power is not enough to complete the power required for the entire boot operation process, then it will continue to cycle like this until the power gradually recovers
