Run down your device's battery until it turns itself off
Turn it back on and wait for it to turn off again; this may be straight away of after a few minutes
Remove the battery for at least 20 seconds
Replace the battery and charge until full and then for at least another hour - while the device is off
Delete you batterystats.bin file using one of 3 methods (requires root): Terminal Emulator - type su then press enter, next type 'rm /data/system/batterystats.bin' (without quotes). Using a Battery Calibration App (from market) - there are many choices available, they just delete your batterystats.bin file. In market, search for battery calibration. Make sure to read review and provided info in case of device incompatibilities. Manually - if for any reason the previous two methods didn't work you may want to try deleting the file manually. Using a file manager with root access (such as Root Explorer) navigate to 'data/system/batterystats.bin'. Delete 'batterystats.bin'
Your device will now creates itself a new batterystats.bin file with a correct 100% battery reading.
Run down the battery until it turns itself off
Turn on the device and charge for at least 8 hours
Unplug the device, turn off and charge for another hour
Unplug the device, turn on and wait for 2 minutes
Turn off and charge for another hour
Use the device as normal!
You really only need to do this very few months or when you change ROM. Providing you don'd change any major settings the battery stats file will remain accurate.
Note:
This may not always produce results because your battery stats file may not be affected at all.
