    If you like to flash ROM and notice that your battery run low very fast. Then you definitely need this app, Battery Calibration simply delete the batterystates.bin from your system directory and when you charge your phone again a new one will be created. This app does need **ROOT**. Give it a try before changing your ROM again because of poor battery stats.

    Another app for root user: recently after I had flashed a new rom,my battery percentage kept going diwn dramatically.I don't have a great battery life anyway but still it was getting worse.And I had observed that if I rebotted my phone often the battery percentage increased like it evrn jumped from 50% to 70%..Now this app isnt a battery life saver,but it will show the true battery life,as it seems that after you flash a new rom,the old rom's battery stats interfer with the present battery. So, if you understood what I said, do give it a try if you have installed a new rom.

    Battery not seeming to last as it should? Recalibrate it with this app. It's not always apps at fault for poor battery life. I've seen much improved battery performance after using this.

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.
