What is battery calibration?

It’s an important thing to know what battery calibration is. We all know that our phones display battery status on the notification bar. Usually, the Android operating system keeps track of your battery and charge level, which displays the battery status in percentage on your phone.

Sometimes that system does not function properly, and the displayed battery status isn’t always correct because of this.

Any phone battery may get damaged with time, as the battery degrades gradually, but the software does not consider this when showing you the battery status.

Battery calibration is a simple process to check your Android OS’s correct battery level.
