Calibrating Android Phone Battery

Last updated: October 2, 2018.

Android Phone Battery Calibration

Mobile phones always come with rechargeable batteries. Each of these batteries’ life lasts 1 to 3 days but still depends on what material the battery is made of. Google powered Android operating system usually uses up more battery life than other operating systems. It has continuous data synchronization. And because of this, a Android phone battery life of 24 hours is usually very rare.

Calibrating the device’s battery is common among those who frequently change ROM. It is advisable then to charge the mobile phone up to 100% and update its firmware especially if you have flashed a custom ROM to your device. For instance, if your battery has 50% life by the time you updated the firmware, the new ROM will detect the 50% as the standard full battery status. The optimum performance it can offer will only be up to 50%. When this happens, you will need battery calibration to gain 100% backup for your battery.

 

 

Before starting the calibration, make sure you have installed the Clock Work Recovery into your phone. You must also know how to get to recovery mode. For Samsung devices, you can hold the volume UP button and OK button simultaneously until a blue screen background is displayed to get to the recovery mode. For other handsets like HTC, you have to hold the volume down and the power button.

 

Steps to Calibrate Phone Battery

 

The first thing to do is to shut off your mobile phone, take off the battery and re-insert it.

 

The next thing you need to do is learn how to get your device to recovery mode.

 

Go to the advance option by navigating using the volume up and down and selecting the option using the power button. Select the ‘Battery Stats’ and ‘Wipe Cache’ to wipe out what was considered as 100% battery life when you previously flashed the custom ROM.
