Hey, after browsing these forums for a while, I figure I should help contribute to the greater mass of the community. 
Anyways, I received an iPad 2 back in February of this year (the month before the Retina iPad 3) with iOS 5.0.1 shipped on it. I have since updated to iOS 6 and then the subsequent 6.0.1 on it and I have found that sometimes if I reboot the iPad 2, the battery percentage is sometimes 5% off and goes up about 5% after rebooting.
The same problem persists sometimes if I plug in the wall charger. It doesn't always go up by 5% but it still goes up immediately and seeing how it feels like I have OCD it drives me nuts.
I also have it sometimes where it'd be a decent way away from the battery being dead and it would say it needed to charge (I was on a Skype call and had 6% remaining and the iPad shut off)
So yeah, I have only had this unit for 8 months now and I feel this is an iOS 6 bug. Anyone else here have this?
