New to the forum, must apologize in advance this might be a long post.
I've had my iPad2 for about 15 months now, of course just out of warranty, and within the past week the battery has gone to hell. Before a charge use to last me 4-5 days with usage and on stand-by the rest of the time. Within a night it suddenly changed to that over a 8 hour stand-by cycle that the battery would lose 30-35%. I did a restore to see if that changed anything and it didn't. Went to the Genius Bar and they ran a diagnostic test on the battery and said it was still running excellently at 100% function. He suggested a few things to help preserve battery life but couldn't replicate the problem.
I went home and did a full clean sweep, getting rid of all apps and settings and shutting off my cellular data, in case that might be the issue. Then let the battery drain down until it died. I recharged it back up to 100% over a 24 hour span. Then I just left it sitting there untouched for the next 18 hours. Over that time he battery drained 60%. I again took it to the Genius Bar and they said that was normal, I disagree and understand that standby still uses battery but 60% really? They said at this point the only thing I can do is live with it and just turn my iPad off when I'm not using it or they can replace it for $250. I don't have the money so I said I'll just live with it and turn it off. That was on Tuesday. I spent Tuesday and most of Wednesday using it very little and noticed the battery was doing well. Thursday it was charged back up to a 100% and I read and used it for a few things then went to bed at 2:30, before going to bed I turned the iPad off with a battery charge of 88% and let it be.i woke up at 1030 and just turned it on and now the charge is it 62%. Since typing this it had gone down to 57%. From my understanding this is not normal at all. The Genius Bar has so far been no help whatsoever and I am out of ideas. Is there anything you can recommend? I'd really hate to spend the $250 but at this point with no usage to very little usage the battery life won't last much more than a day.
Thanks for any help you might be able to offer and sorry for the long read.
