So I updated to 4.1 from 3.1.2 here the other day. It was fine for a couple of days, but the now battery life is horrible! It only need to be on standby for a few hours before its empty. I've seen that a lot of others have had that problem too. I tried turning of Notifications, but that didn't work. Any other solutions? Do I need to update again? I rather not, since its a jailbroken. Since its jailbroken I can try to download some of those Battery log apps from Cydia if that helps. Its a iPod Touch 2g/3g MC model.
