Loving my iPad, but I'm a little confused about the battery life I've been getting. With Wi-Fi on, video playing, and screen at 3/4 brightness, I get an 18% dent on my battery per hour. My iPad is usually dead in less than 6 hours. Do you guys think this is grounds for an exchange? Would I just go there and ask for a new one, or should I make a Genius appointment? I'm reading reviews and personal accounts of people getting 9+ hours watching video, and I'm just not seeing it. Even browsing the web for the last hour I've seen a 13% decrease from fully charged. Just want to be getting the most out of the device. Thanks for the help!
