I know there's been a lot of discussion about this but I thought it might be good to get some real observations together. I went to bed and put the iPad 2 on charge at about 0200, at that time it was at ~31%. I got up this morning at 0700 and it was up to 85%. By 0830 it was up to 100%. I woke it up (smart cover) and did about 15 minutes of browsing ipf while still on the charger. That brought it down to 97%. I put it back to sleep and 20 minutes later it was back to 100%. BTW what happened to all the great usage stats from the iPhone 4? After about an hour's casual usage (without charging) it's now down to 84%.
It seems to me that it's pretty hard on batteries and is fairly slow to charge. I also had trouble believing that using it while on the charger would deplete the battery. Since I did not have an original iPad and have only my iPhone 4 for comparison, I'm not sure if I have a problem or not.
How does this stack up with what others are experiencing? Maybe we can do some real comparisons--Apples to Apples --and try to figure out what's normal and what isn't.
