Calibrate your Galaxy S2 battery successfully without rooting or using any third-party apps, by following a few simple steps.

Battery Calibration is an extremely wide topic in the world of mobile phones and there are so many methods and apps that are said to calibrate your battery that it becomes so difficult to choose from so many. However the Galaxy S2 battery cannot actually be calibrated using normal methods. This is because of the drivers used by the battery. However there is a simple method that doesn’t require any root or to install any apps.

A successful battery calibration allows for 100% charging and no drainage after unplugging the device

Before doing this, you have to know that the method is 100% effective, however whether this will actually work or not for your Galaxy S2 device depends on what other apps you have installed on your device that might drain the battery. Battery drainage and calibration can also be influenced if you have a custom kernel or ROM. However for the most of you Galaxy S2 users this should bring you more battery life and also it will allow your Galaxy S2 to charge to 100% and stay there longer than a few seconds.
