Oddest thing just happened to my 3G iPad. I have the unlimited AT&T plan and always have full bars. I unplugged my iPad at around 7:00 this morning. I get to work and fiddle with it for maybe 30 min. The iPad has a home right next to my computer in my office. I leave it there from about 8:00 to 12:30. When I turn it on to check this forum I notice that my battery is down to 51%. What the heck? Nothing was running and I have my own locked office so no one messed with it. Even more interesting it is now down from 51 to 49 while I am writing this post??????
