    i thought this firmware will improve battery life, but mine is the opposite. i'm losing 1% every 5 minutes of surfing with wifi, not even 3G and no video streaming. i'm considering drain the battery completely and charge it up.

    Same on my end. Fully charged this morning at 10:30, its 1:30 and I'm at 88 percent with minimal to no usage at all...

    I used it for light browsing for about 5 to 10 minutes and nothing else.

    ^Original iPad or iPad2?

    I noticed a decrease in battery life when I upgraded to 4.2.1 (original iPad)

    If this is the case I'm going to wait it out on 4.3

    1% every 5 minutes isn't bad. That is 500 minutes of battery life total, or 8 hours and 20 minutes. That is about 83% of what Apple says, so that seems reasonable.

    Same for my 32GB iPad 2. I left it yesterday when I went to work and it went down 3% in 10 hours with no usage. That's far below the one month of standby time (13.888 days). I used it til it went dead and recharged it last night. Lets see how it is when I use it when I get home today (left it plugged in all day).

    With 4.3, it would go down maybe 1% while I was at work. Sometimes it was at the same pecentage as when I left, but would go down 1% after a tiny bit of usage.

    Hopefully the battery just needs/needed to be calibrated again.

    I have noticed reduced battery performance as well. I feel like I lose a percentage point every 5 minutes of wifi use. Based on math it seems reasonable but I could swear I got better performance prior to iOS upgrade.

    Same here ---iPad2, 64GM, Wifi...left the house yesterday and the battery was at 94%...when i got home about 10 hours later it was 10%+ lower...nothing was "on", no multitasking...for comparison purposes, my iPad1 (same exact config and applications) would hardly show any drain across the same time period

    Have you disabled Ping?

    I read on another thread that doing so could decrease the rate at which the battery drains since it is not always working.

    I don't know what the heck it does, and I don't remember how to do it off the top of my head (since I left my iPad at home). But search for it and see if it helps.

    2% for one hour, not bad. I left my iPad 97% charged and came back 8 hours later and still at 97 %. net.. Zero. There are times I've used it 8 hours straight and I got 24 percent left. :)

    try recalibrating, drain it to zero then do a full recharged.

    my iPad is going on 9 hours 5 hours standby

    moderate use

    still at 58%

    i think its a subliminal subconscious thing. They said improved battery life, so i was expecting a virtual battery latched on for extra hours of use lol. I'll try to drain it today and do a full charge.

    After I updated to 4.3.1 I drained the battery and did a full charge over night...I think that was on Sunday. On monday night (last night) I had 70% left so I decided to charge it over night again. Woke up at 100% at 10:00. Got to work at 10:30, played some music an hour (wifi off) then did light browsing for 5-10 minutes with wifi on and it went to 88% by 1:30.

    Left for lunch, turned off wifi, no apps running, came back 30 minutes later and its at 86%. It's now 3:23 and its staying steady at 85%...Maybe i should log all this more accurately lol. in retrospect...yeah i shouldve.

    For some reason it seems like 90-100% battery life gets eaten fast. But 70-80% goes slower? i dont know.

    do you find the battery getting used faster on 3G in certain areas and not in others? like the 3G is using more juice when its in spotty areas of coverage...

    Mine seems fine after updating. Still gets me through the whole day with plenty of juice left. I leave wifi and 3G on constantly.

    so is it safe to say...as we upgrade from 4.2.1 to 4.3 then to 4.3.1...4.4 etc etc battery life will continue to get worse?? I hope this is not the case.

    I unplugged it yesterday when I got home from work and used it for a few hours then put it away and fell asleep (don't remember the %). When I woke up this morning, it was at 63% (though I left Twitter open, don't know if that matters).

    When I left work this morning at 7:50, it was at 63%.
    I'll let you guys know what mine is at after I get home from my dentist appt.

    My iPad started draining quickly after the update
    Sitting idle it would tick down dramatically
    Today, it has been on my desk all day 8 hours, and I read a good bit at lunch
    It still shows 99%

    I stopped the drain by disabling Push and only using Fetch
    I also disabled some location services, but I believe the leak was in Push for me

    I charged my iPad 2 overnight last night. I took it off the charger at about 8am. I haven't used it all day, but it was in standby with the smart cover on it. I just opened the smart cover now at 4:38pm and it says 100%. Looks like mine isn't draining at all. I'm running 4.3.1, and I have ping disabled and don't use push email.
