Android's settings menu has a battery statistics indicator. This feature allows the operating system to monitor the current battery level of the device. If the battery is not calibrated, it can sometimes send incorrect battery statistics to the device's operating system due to incorrect battery level detection. As a result, the operating system may shut down the device even if the battery level is sufficient. Such unwanted problems can be solved by battery calibration. Note that the battery level on any device suddenly changes from **bleep**% to zz%. The main reason is that the "BatteryStats" file has been damaged. This can happen for many reasons. This can be solved by calibrating the battery.
