    I have the cellular version of the latest maxi iPad, and somehow it feels like it lasts a bit shorter than the 2, which I had prior. I note that some reviewers said that as well, and I was wondering if it is the case. I can figure out why it could be shorter, given the screen and the extra processing oomph, and it isn't so short that I can't do anything, so I'm not disappointed or anything.

    My iPad lasts an incredibly long amount of time. I usually end up charging it every two days with casual use. It really depends on what you set your brightness to. If its set on 100% then your device is going to drain through battery power relatively quickly.

    I have the brightness set to auto-adjust, and I use the iPad in relatively dark places most of the time. The brightest it gets is when I'm in the bus heading somewhere and it's sunny outside - if not that, then it doesn't get horribly bright.

    Granted I have the WiFi only (No LTE) version, but the battery life last way longer than the iPad 2 for me.

    LTE chews through battery life, even on standby. when you know you won't be using LTE, turn off cellular and watch your battery life drastically improve.

    also, i found a lot of quirks with my iPad 4 were solved with a full iOS restore (erase data and settings). for some reason, initially it was stuttering and heating up really badly. after i wiped it clean and restored it again, everything went back to normal.

    perhaps your battery life will improve too

    Damn, even though I have a 3G plan? That sucks...

    Maybe I should just ditch my backup and do a full restore as well. Thanks for your input.

    This reportedly worked for the iPad 3. Might be worth a shot. Good tip.

    just finished an article comparing Tablet battery life. Ipad with retina is the best in its class of around 13 hours with wifi on. Ipad 2 is 9.30 hours.

    Like above comment, i think LTE will eat your battery like lunch time snacks. Im wondering whether i should sell my 2 and get a 4????

    only if you truly need the Retina display. but a word of caution - once you go Retina it's very hard to go back.

    if you want Retina, i advice is to get an iPad 3 16GB refurb for $379. if you need more space then get a 32GB for $449. the reason why i say this is bc i have used both the iPad 4 and iPad 3 extensively and the difference right now is negligible. if you are thinking about getting the iPad 5, you would be flipping it in the near future and the iPad 3 refurbs will actually depreciate less from the refurb purchase price than a brand new iPad 4 from the full retail price

    i ended up ditching my iPad 4 bc of light bleed issues and got the same 64GB LTE config for $679 (vs $829 for the iPad 4). for anyone who says the iPad 4's added resale value will make up that $150 is a giant fool

    My 4 lasts bit more then the 3, but less then the 2 and 1. BUT it lasts the day, when I get home, I have enough charge to use it for an hour or 2, then it hits the charger and left overnight for another day of abuse :)

    My iPad 4 Wifi lasts about 14 hours with a full charge. My friend has an iPad 2 and he gets 8 hours on it...

    Eventhough Retina display uses more power than iPad 2, Ipad 3 got a major batery capacity boost. So comparatively both should have approx. same battery life time. Ipad 4 should be same as ipad 3. As some people already pointed out it really depends upon the brightness and graphic intensive apps.
