Let us know, battery life on 4.3.1 is a joke, I've never had problems with battery life before, mine has been cut in half by 4.3.1, not happy at all.
weird. regarding battery performance/life; 4.3.1, for me, has been just as good as 4.2.1 if not better. i read in a other thread somewhere else that you have restored as new but i also know you jailbreak
maybe try restoring as new again but wait on jailbreaking and start a process of elimination, just a thought..
