I am going to move this to General Discussion. You have currently posted in the iPad Poll section, where you probably won't get as much attention.
Also, I have not experienced any battery issues since I have updated to 5.1. I did it on Friday afternoon--and it is seems consistent. Hope that helps.
I never had a problem with charging or battery life before the 5.1 update but so far it hasn't affected anything negatively. Actually, it seems the same to me.
I actually upgraded to 5.1 because it was supposed to give better battery life. Now the charge seems to drop like a stone, quite the converse of what I was expecting.
Well I charged my iPad last night, began using it about 11:30 am. Have been on this site and a few others off and on today-I am now at 77%. So with all this talk about recent battery drainage since the recent update, I will pay more attention.
