Calibrate battery on your android device

For smartphone users, battery problems are the biggest concern. So to overcome this problem I am writing this short tutorial to calibrate battery.

Battery issue generally develops after flashing ROM or updating the firmware or software updates. There are some myths that deleting batterystats.bin file will re-calibrate your device battery. But this batterystats.bin file simply stores all the info of your battery section. This file gets updated on each time you charge your device above 80%.

There is a warning before we update the firmware or flash a ROM the device battery should be 80%. But most of us ignores that warning and continue it without charging it to 80%. So whenever you update or flash ROM you need to calibrate your device battery to get good performance.

In this tutorial, I am writing two methods to calibrate battery on your android device. The first method for non-rooted android devices and another one is for rooted android devices.
