How does one go about rolling back the firmware as i have a feeling this was the cause why its so bad now.
Is it the S2?
Turn off your background data (settings > accounts and sync)
Turn off Use Wireless networks and GPS (settings > Location and security)
Turn off your mobile data unless you're using it (settings > wireless and network)
Turn off Wi-fi unless you're using it (settings > Wireless and network)
Doing this will save your battery big time.
As PTR says, get CM7 on it, loads of tutorials on it on the net. Mine lasts well over a day and a half now, but charge it every night anyway.
