Hello guys. Last night my iPad 2 had 98% battery left after some hours of recharge. I took my iPad and started watching some videos and all kind of random stuff. After about an hour and a half, the battery said 93%, which kinda impressed me cause it should have lost about 15% if the 10 hour battery life holds true. Well i put my iPad to sleep (did not turn it off) and when i woke up next morning about 9 hours later the battery monitor said 85% left. For me it looks like it need some time to actually figure out the exact amout of battery left? Have any of you tried something similar?
