Android Battery Calibration Phone, Tablet And Extend Longer Battery Life

Battery recalibration should do after the flashing a ROM, or if you feel battery is miscalibrated. There are mainly two ways to do this one. Manually and using an Android application. However to calibrate, you need to root your Android phone (methods in here and in here). If you don’t have root permission, you can use our newest guide How to calibrate android phone, tablet battery [ no root, with root calibration ] guide.

The importance of this process is after the calibration, it will give you more accurate battery level. Because of, after flashing a ROM sometimes old battery “batterystats.bin” files still remain. To remove it you have to do it.

Following android’s battery calibration methods can be used all the devices. No need to follow all the methods that I mention below, you can follow only one procedure. If you follow all the methods, is not an issue.

• Turn on the device.
