I upgraded my LG optimus P500 phone from Android 2.2.2 to 2.3.3.
After upgrading the battery started to dry very soon and it auto powers off as well even when the battery is more than 80%.
Now I want downgrade my cell back to original froyo 2.2 version.
How can i do this?
Or is there any other fix for this problem of battery and auto power off.
