I have found that my battery life is absolute shite no matter what I do unless I use Juice Defender and switch to EDGE over 3G/HSDPA. I lost 12% batt in about 1hr 30mins, with Android OS being the highest user, despite the fact that the screen was off the whole time and there was basically no waketime either. It's just dreadful. Looks like I'm only going to be using 3G when watching youtube or for any heavy surfing sessions/tethering. Can't afford the battery drain otherwise.

thanks for da quick reply sifoo.... im a big fan of galnetmiui before,but
their version for sgs 2 not stable enough.. so maybe im gonna try lite'ning rom.
