This is a quick, functional tip that helps you increase the battery life of your Android phone.
Before you start, you need to have the latest ClockworkMod recovery flashed to your phone – so, install ROM Manager from the market place.
Note: You can flash ROM Manager only after rooting your phone.
If your phone is a Commtiva Z71 variant running Firetrap JellyBean ROM, you don’t need to install ROM Manager.
Charge your phone’s battery to 100%
Reboot the phone in recovery mode, go to advanced, and click on wipe battery stats. Unplug. Use the phone until the battery drains and the phone switches off. Recharge again to 100%.
Note: Entering into recovery mode will vary from phone to phone. Consult your phone’s manual. If it’s a Commtiva Z71 variant (Motorola XT502, Orange Boston, Apanda A60, A88, etc.), you need to press and hold camera + volume up + power buttons.
You should now be seeing a 30% (at least) increase in battery life, before it drains off completely. I repeat this process once every fortnight, and I get 2 full days of charge with fair internet usage over HSDPA, Wi-Fi, voice calls and SMS, on my Motorola XT502.
