Battery Calibration

Battery Calibration


Requirements: Android 2.1+ | Root permissions

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 closley follow the changes.

Recent changes:
- Option to beep when 100% is reached.
- Voltage meter added.
- New icon.

User reviews of Battery Calibration
deleting batterystats.bin does NOT calibrate your battery, the full charge and discharge that they recommend after is what will calibrate your battery. see this for info from an actual android engineer: https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT dont waste your time with this! batterystats,bin is recreated when you fully charge it is simply the info re: battery usage in settings

**USE THIS IF YOU FLASHED TO CM7 / CYANOGENMOD 7.1.0 AND YOU'RE HAVING BATTERY DRAIN ISSUES** Works as advertised, after I upgraded from Eclair 2.1 to Gingerbread 2.3.7 on HTC Hero CDMA (Sprint).

Simple. Needs root! Only required when you changed your OS.

Awesome Big difference. Thank you for the much needed app for a fresh ROM install...to everyone out there blowing up the reviews for this app with bad ones...I hope your rooted properly.....just a heads up...if you calibrate at 100% like it says (not when your phone says 100.…when the app says 100%) then you have to make sure you follow instructions and fully uncharged and fully charge again with no interruptions...if you only get to 50%, that's the most your phone will charge up to
