Battery and adapter switching circuit improvement Experiment

Purpose:When many single-battery machines are under heavy loads, for example, if the backlights are switched to the brightest light and 3D games are run, pulling DC power is prone to machine crashes or blurred screens; Cause:Q5's conduction time is not enough. It is expected to speed up to the conduction time through the fast discharge of G pole; Circuit before modification: (Switch when the battery

For Android, "set-) battery used time"

Procedure: 1. Choose Settings> battery> View battery time in use. Actual results: The battery time used is from the start time to the current time, instead of the current time after the charger is unplugged. The accumulated battery usage time is google default, but this may cause a serious problem: If batterystats. bi

How to extend the battery life of a smartphone
