If you're a rooted user, chances are that you flash new ROMs fairly often. What you may not know, however, is that your phone saves the battery statistics from old ROMs, and if you've never recalibrated your battery before, then your time away from the charger may not be as good as it could be.
Resetting battery stats can be an intimidating task for those who don't spend a lot of time in recovery (or who have never even booted into recovery). Fortunately, XDA member marosige has created an app that makes battery calibration a snap.
It's really simple (the instructions are even clearly stated within the app) - launch the app, charge your phone to 100%, unplug it, and tap the "Battery Calibration" button. The recalibration process will begin at this point, and generally takes a few days to complete. Use your phone normally and enjoy the additional battery life!
As always, check out the support thread in the XDA Forums if you have any questions.

I'm using a 3500mAh extended battery on my Evo. Wonder if this will improve battery life even greater. Will let you know.
What, no QR code?
This one is only available on XDA for the time being.
anybody can attest if this works?
On Nexus S is not working because I couldn't reach 100% charged battery at any time since I got my phone 3 weeks ago. It stops at 98% and the application require the battery to be charged at 100%.
Therefore I couldn't test it!
The OP in the XDA post had this to say http://forum.xda-developers.com/showpost.php?p=12728498&postcount=10
I'm going to test this later on today with my husband's Droid X. Does anyone else with a Droid X know if this works?
yes it does work. but then the next day it didnt fair too well. the first time i calibrated it my batt life with full charge lasted me 15h the next day i saw maybe about 8-9h which is still pretty good so to speak
Yeah this hack is fully functional, my samsung galaxy s GT-I9000, the battery duration is the 2 days... Repeat only Samsung Galaxy S GT-I9000
Hi!
A new version is avalable on Android Market.
QR code is in the XDA Thread!
you don't need an app to do this- many recovery roms will allow this file to be deleted, or you can delete it yourself if you are rooted.
