Battery backup is one of the biggest problem in Android devices. Even though Google have added some new battery tweaks in Android Kitkat which makes it last longer than usual but still it's not at its best phase. On an average battery backup of android devices is around 8 hours. But if you have noticed a sudden decrease in your battery performance like the battery is draining too fast or your phone switch off automatically at 5-6% battery level (and shows 0% when you turn it on) then its the right time for you to calibrate your device's battery.
What Does Battery Calibration Means?
In all android device there is a file names 'batterystats.bin' which saves the battery information. When you charge your phone multiple times daily, when the battery is not even half empty, this file become corrupted and shows wrong battery stats, which causes the phone to switch off before it reaches 0%. The process of repairing this corrupted file is known as calibration.
How often should You calibrate Battery?You should calibrate your battery every week. You should calibrate battery even if you are not having any kind of problem with battery to keep battery state healthy.
