    Hey new user here I just bought a used ipad (owner had it since april) and I have never owned an apple product but I thought this thing got 10 hours or around that.

    With 4.2 which is all I have used I get about maybe 5 hours gaming (what I do mostly. Also I am at full brightness and probably streaming music. I am jailbroken so I don't know if that matters. Is this normal or should I take it to apple store will apple replace it since it's still under warranty.

    Also I wanted to add that it takes about 8 hours to charge.

    Something's up with your iPad - you might need to take it in. Mine discharges ar ~10% an hour so I get 10 hours doing pretty much anything, more if I'm just reading or browsing. It charges at 1% a minute when plugged into an outlet, so it's never more than 100 minutes (1:40) to charge. I've noticed no change in this behavior since updating to 4.2.1.

    I used my iPad until 1AM last night and ran it down to roughly 10%. Come this morning, 7 hours later, it's sitting at 90% after charging. Should I send in my iPad?

    Full brightness on that screen is essentially like staring into the sun. At half brightness you will get about 10 hours and lowest about 15.

    As for the 8 hour charging....don't use your iPhone charger....make sure you use the charger supplied.

    My battery life is exactly the same, I even did a test streaming high quality video over wi-fi the entire time before and after the upgrade.

    What tweaks/apps from cydia do you have installed? That can account for a lot of battery drain.

    He also said he is gaming. That eats a lot of battery. I'm back on an extremely boring long-term test at work and I have used mine intensively with emails and web browsing for about 8 hours and I'm still at 55%.

    If you're using the supplied charger, I'd definitely investigate the matter. Mine's never taken that long to charge.

    Yes, I'd say that heavy duty gaming with screen at full brightness is a big battery drain.

    As for the slow charge, several people have mentioned this now and it would be nice to know what is causing it. What apps do you have running in the task list (double click the Home button and look at the bottom of the screen.) I know most apps in the task list are not really running, but some can run, like music apps. If we can find something common amongst the people who are having this issue it could help.

    If you think you are having serious problems, take the iPad to the App store and see if they have suggestions. And please report back here because a lot of people are wondering about this problem.

    I remember reading a couple battery tests one site did when the iPad first came out. Under normal use of Wi-Fi and video at low/med brightness they pulled about 15 hours, which is on par with what I've been getting. But when they ran a 3D game, they were able to run down the battery in less than 6 hours.
