    When I leave my phone off the charger overnight pre-jb, it still shows 100% or 99%. After jb, its showing 93%.

    Also when I did light surfing, it seems to drain more.

    Also something weird happened. It was at 88% battery life when I put it on the charger. After 10 minutes, I took it off and it was still at 88%. I restarted the phone and now its showing 90%.

    Might take the phone a few days to adjust to JB it should get better though

    With the regularity of the seven year locusts, thus arrive the 'jb killed my battery' threads. :D

    Me, too. I can't wait for the explanation for how the phone adjusts to jb.

    Let's see, yep, the jb is a little tight at the shoulders, sleeves are a little long and it's really tight in the crotch. We'll adjust that and everything will be fine.

    I know people always deny it, but JB has always decreased the battery life on my previous iPhones.

    My battery has been worst. Lastnight I passed out around 80%+ and I wake up with 53%. My battery is very good normally.

    Here are the JB apps I have installed:

    Cydia
    Lockinfo & plugins
    Backgrounder
    Bitesms
    Installous
    Terminal

    I wonder if it's lockinfo that's draining my battery. If so, I'm going to have to ask a refund.

    I have backgrounder on my iPad & it doesn't drain it this much but that's a possibility. I wonder if bitesms drains it a lot also.

    Well, your ipad has a massive (actually 2) batteries. So not an equeal comparison.

    Of the things you listed, only Backgrounder should affect battery.

    I have lockinfo and its fine.

    All I installed was MyWi 4.0.

    I'm running iOS 4.0

    I'm at 90% battery, 46min use and 4 hours stand by

    I don't think the culprit is bitesms. I would look at lockinfo or backgrounder.

    app for battery percentage per app

    is there an app you can download that tell you which apps are draining you battery and how much? because i seem to be losing a % every minute or so. its insane! i just dont know whats doing it, if i did i would get rid of it/them.

    thanks

    I forgot about that. You're right, that was a bad comparison. That's good to know about lockinfo

    I also forgot I install WinterBoard. I'm going to uninstall backgrounder & WinterBoard to see if I get any improvements.

    Thanks for all the good info & ideas.

    Winterboard can drain battery depending on how nuts you go with it. Moderation is the key, lol.

    Or you could just chuck it.

    MyWi is a battery drainer, even when you're not using it. Of course, it's worse when you are.

    Auto-Brightness screwy after JB?

    I just checked out auto-brightness on my iP4, and it doesn't seem to be functioning like it was before. Even in a dark room, it appears to be delivering 100% brightness... Can anyone confirm this on theirs?

    For the record, I didn't download the post-JB update though Cydia to restore Facetime and MMS, I just restored from the iTunes backup I made 10 minutes prior to jailbreaking.

    Same here, although I never use it so it's no big deal to me

    This is good, isn't it?

    (46 minutes * 10 [you've used 10% of your battery; this multiplies it out for 100% usage, approximately because different things drain the battery quicker or slower]) ÷ 60min/hr = 7.67 hours of battery life.

    Yeah, that's true. Also, every third Tuesday of each month (except in March) it's goodness will improve by 3.9%
