    PC Mag did a few tests on the new iPad and found out that should mean a lot to all of us. With the new screen set at maximum brightness, the iPad would only play video for 5.5 hours. The iPad 2 would get almost 8 hours. With the brightness set at 50% the same video test lasted 11 hours. For those with concerns about the demands of 4G, the new iPad managed to do 25 hours of 4G streaming on a charge.

    To show the how much of battery demand the new iPad has, look at these numbers. The iPad 2 has a 25 watt-H battery. The MacBook Air has a 35 watt-H battery. The new iPad has a 42.5 watt-H battery, but it is using the same charger as the iPad 2 (10 watt), but the MBA uses a 45 watt charger. It takes the new iPad 7 hours to fully charge, while the iPad 2 took 4 hours. I wonder if this would be a great opportunity for a vendor to design a 25+ watt charger for the iPad?

    can't imagine me ever running my iPad at maximum brightness, when mine is set at maximum it's almost unwatchable, and even too bright when in bright sunshine.

    In the home, I find around 40 to 45% brightness gives a really superb bright picture

    The dock might be the limitation to going to a beefier charger.

    I keep my brightness bar in the dead middle, but I keep auto-brightness on. If I turn auto-brightness off, my iPad always immediately gets much brighter. I'm not even at 50% most of the time.

    The idea of anyone using 100% brightness blows my mind.

    From fully charged mine managed just over 8.5hrs, that was with brightness at it's usual 45% and I watched 2 x 2hr films, couple of hours TV streaming, bit of web browsing, and listening to music with bluetooth headphones for about 1.5hrs too, so not too bad at all. I don't think battery life is too much of an issue at all. (3/4g was off)

    You have to remember that a lot of novices have not learned about the brightness setting, nor how it could affect the battery life. One of the function of these forums is to educated the new and long time owners of this device to better enjoy its features. Even if it does not affect us directly, we can pass the information on to our friends and family with iPads.

    Perhaps there should be a "best practices" FAQ type thing...and on it should be the list of the perils of 100% brightness 24/7. That would be quite a list, I think.

    50ish percent for me, not for battery but for comfort. 100 percent is like staring at a lantern.

    Yes 100% brightness would be like a lighthouse to me too..and I'm amazed to read that some users have their set so hight... hmmm.. strange.

    However 'seadog' does have a point, it is possible that there are members who have not yet got fully into their iPads unlike some of us who are possibly on their second iPad. I'm now retired, but was in the TV repair business for many years, so in effect have 40years experience in that trade, (going back to when Valves/Tubes were used...lol) so what may seem second nature to myself and perhaps some others, I acknowledge that it's easy to forget that not everyone may be conversant with things that seem obvious to us... so have taken 'seadogs' comments on board. :) Though one has to be careful that having to explain something so obvious as brightness may come across as a little patronising, but yes I suppose it is possible that some new users may not know how to adjust it. :)

    I can't see how anybody likes 50% or below on brightness. Mine seems too dark so I keep it at around 70%. My battery last all day even watching tv and movies - 80% of my iPad is 4G too!

    It depends on who they are. A true geek is going o crawl through every option and setting within an hour of powering up a new gadget. We don't believe in defaults.
