If you’ve liked our articles Tips about Li-Ion batteries and 4 busted myths about battery life , then you’ll surely love the Calibration app. Basically, Calibration needs to be done after flashing a new ROM, but you can calibrate any time you think your battery is miscalibrated. This program does it by removing the batterystats.bin system file. The OS generates a new clean batterystats file soon, thus any fake information from the previous ROM is removed.
- It’s suggested, but not necessary, to let the phone fully discharge after calibration, then charged to 100% without break.
- The app shows your actual battery status, and only allows you to start the calibration (i.e. removes the file) when it’s fully charged, unless you force earlier calibration.
- The voltage meter can be useful too. Full charge is around 4200mV.
- There is an option to beep when 100% is reached so you don’t have to closely follow the changes.
