    So had my 3G iPad now for about a week and the battery life compared to my old wifi version is terrible. I used to be able to get the 10 hours advertised with my wifi only model but with the 3G I reckon I only get about 4/5 hours tops. Just general browsing, emails, and games with a few you tube vids. Only browsing using my wifi network at the moment so not even tried using a 3G network. Brightness is set half way. Push notifications are on but only for bay app. Email set to retrieve every 30 mins apart from MobileMe which is also push. Location services are on and Bluetooth is off. Cellular data is on as is wifi but not actually using my 3G signal. At first I thought it could be because I used the restore from my old wifi version so did a fresh install and still no change. Just played predator the game for about 15 mins and lost nearly 10% battery. I believe I've been charging battery as it should. Ran it dead when I first had it then fully charged over night. I try not to stick it on my dock when it's not in use. So only charge when needed. Do you think the batteries faulty or is it just me.

    Cheers

    Do you turn the 3G radio off when your not using it?

    The battery in my 3G iPad seems to last a long time. I'm pretty sure I get more them 4-5 hours, although I never really think about it.

    No I don't switch the 3G radio off when it's not in use. That's the only difference in my setting between this one and my old wifi one.

    May have to make an appointment with a genius I think.

    Blimey!

    Is there any kind of test I can do to get accurate battery times?

    There are various utilities that will give you remaining time. I use amonitor. It currently says I have 6 hrs left if I use 3G and I am currently on 63% battery remaining.

    I've never discharged the iPad's battery completely so I don't know its autonomy but I did notice that on 3G it consumed more. I blame it on the radio. Speaking of which, when I use 3G I turn off the wifi radio...

    Well i downloaded a monitor app and after a full night of charging it says I have 10 hours of wifi and 9:30 of 3G use. So I'll see how it goes today. If not I'll take it back and swap it for another one.

    I tend to leave my 3G on and get a good 10 hours+ out of it. I do live in a fairly strong 3G signal area though, which I think makes a difference.

    I think it does too. It's the same with cell phones.

    The amount of battery drain is also directly predicated on the Apps that you use as well.

    Well I've been out all day so haven't had a chance to use the iPad much. But when I left it was on about 95% got back about 4 hours later and it was still on 95%. So I can only assume that's good? I do have a very good 3G signal where I live so would like to leave the 3G radio on but at the minute it's off as is push email. I'll just have to see how it goes.

    Cheers

    I forgot about push.. I did that on my iPhone and well, my battery dead in about 10 hours. Before I get off work it's dead with very light use (email, facebook, 30 texts).

    With push off, I use about 1/4 of my battery. I have push on the iPad and still receive great run time.. So I dunno

    I just dim the screen, don't turn wifi or 3G off, and get 10 hours or so, even playing video.

    Yeah my brightness is set to 50%. Maybe mine just needed a few charging cycles to fully hold charge. Been using now on and off since 10am yesterday and still got 60% left. So maybe it ain't all bad.

    Apps do make a difference as well as push and what kind of 3g area you're in. I leave my 3g off unless I need it. In my work and home I can move around and the signal flops about its frustrating but that's ATT for you. I also take my iPad with me all over the place and I certainly do not want to waste my battery with the 3g trying to stay connected and I'm driving along with it in my bag!

    I played a "Spider" game that was recommended to me and it killed my battery as it was very intensive set up... so apps matter also.

    Good luck with your testing, I'd definitely give it a day with 3g on all day and a day with 3g off all day and see what differences you get.. there are so many variables (usage) that will still not be "scientific" results.

    I don't get why anyone would leave 3G on if they don't have a data plan. The O P says "not even tried" 3G, so I wonder what the perceived benefit is. I've only turned mine on a few times in 3 months to see what the reported signal was.
