I've had the same problem as well, but more so with my iPhone 4 than iPad. It doesn't come anywhere close to how it did prior to iOS 6. Woke up the other day at 7:30 and unplugged the iPhone at 100%. Sent 3 texts and put the iPhone down. Went back to bed ( I was sick) and 4 hours later the battery was at 23%????? What the heck? Hadn't used it at all! Is there some new settings in iOS 6 I should be looking at or changing? Brightness is under half.... Most location services turned off..... Not thrilled right now. Hope there is something I'm missing. ( iPad just went from 83% to 77% while typing this!?!? Maybe it is affecting my iPad 3 as well)
