    IPad2 battery percentage does not update...at all

    A few days ago when I went to use my iPad after having charged it all night it showed the battery percentage at 97% and would not charge further. After turning it off all the way and then turning it back on I was able to get it to show the charge at 100% where it sat for the rest of the day even with heavy usage. Based upon my experience it should have read something in the 60s.

    Later that evening I shut it off again and left it off for 20 minutes. When I turned it back on, it seemed to hang in start up before displaying text on the start up screen that I of course did not get a picture of, but seemed to indicate there were problems loading. I'd say it was on there for just a minute or so before the usual start up screen appeared and then it sat for an unusually long period of time before loading again. From there the battery percentage drained quickly and ended in the 50s. I was able to plug the iPad in that night and the battery charged as normal to 100% and then the usage percentage updated the next couple of days as normal.

    This morning it was only at 91% after charging all night and when I unplugged/plugged back in it updated to 100% almost instantly where it has remained all day. My kids have played games, I've checked my email, etc. it should be at least in the 70s at this point based upon my previous experience. I've called Apple support because it is still covered by AppleCare until April. They were...not helpful. I got the spiel about the percentage only being an estimate and then he said something to the effect that he couldn't understand why I was calling. He suggested resetting my iPad without restoring from back up which I have done. There is no change. My iPad still thinks it is fully charged even though it's been in use all day. This isn't an estimate, this is fairy tale land territory. There's just no way that's even remotely accurate.

    Is this a hardware issue? Should I make a Genius Bar appointment and drive an hour away to the Apple store to see if they can figure it out?

    I would close the settings app in the task bar and then go to Settings>Usage turn off Battery Percentage and turn back on. See if that changes things.

    I've tried that as well, but no change. Both the percentage and the little battery icon remain unchanged.

    I did try powering it off for an extended time again tonight (more than twenty minutes) and that's the only way that makes any difference. It's down to 81% now, but it hasn't changed in quite a long time.

    Have you been draining your battery down to zero once a month? That is what Apple recommends to help calibrate the battery.

    In addition to skimonkey's advice, I use a free app for monitoring things like this.....

    https://itunes.apple.com/ca/app/sys-...447374159?mt=8

    Follow instructions in the app to calibrate your battery settings. Hope it helps.

    Thank you both - you've already been infinitely more helpful than Apple support. I have run the battery down, but maybe not often enough. I'm going to give it a try and see if it helps!

    Interesting....

    Tells me my iPad 2 has 5 apps running including phone service. None show in the "Task Bar" area but even then it might be believable if it wasn't a wi-fi only iPad.....

    I did try running the battery down once iOS finally showed an accurate percentage/level on the battery indicator. I let it get down to 16% and then ran a full recharge with the app. It got to 100% the next morning where it stayed the whole day. I decided that it probably wouldn't let me charge it since the iPad thought it was fully charged (as did the app, naturally). It continued to say the battery was at 100% all during today (the second day) until just a few seconds ago when it updated to 21%.

    It seems like iOS has no idea what's going on with the battery. Any ideas?

    Just an update. It appears this may be a known issue post 6.0.1 software update. Mine was the second iPad @ the a Genius Bar tonight with the issue. The battery is just fine, it's most likely a firmware issue. They updated/reset my iPad again and if that doesn't fix it then it's probably a hardware issue. 6.0.2 is supposed to fix the problem that caused my firmware issue. Supposedly, anyway.
