    It's no big deal, but I put my iPhone to sleep, at 97% battery charge, and I woke up with 80%... is that normal or is it doing stuff during the night that it shouldn't be, or doesn't have to be?
    I've got everything turned on except Fetch which is set to manual.

    It depends on your settings, do you have apps that push, etc.
    It is possible depending upon what you've got going on there.

    Yeah, I turned Fetch off because it vibrates when mail comes in and that would go all night, so that's not the problem.
    Push notifications could be it? I don't know, I do have apps that push, IE FaceBook etc... only one or two though.

    I've pretty much got everything turned on that can be turned on, could push notifications (even if there are very few) drain the battery like that?

    That does seem like a pretty big drop. Are you jailbroken? Are you on 3.1.3?

    I actually tested this last night. I went to sleep with my iPhone at 100% and woke up with it at 95%. I was testing this because I was having major battery problems with my jailbroken iPhone, among other things, so I restored it. Ever since I restored my iPhone and set it up "as a new phone" I have been really impressed with the performance of the phone. I don't think I'm gonna go back to a jailbroken phone again.
