I know the iPad's battery life is great, but I think mine might be reporting it incorrectly.

I got a replacement yesterday for a dead pixel, the new one seems to always be 100%. I haven't used it a whole lot but it's been almost 24 hours. I do plan on using it for another few days without plugging it in and see what happens.

Anyone else experience this?

Interesting. I just had mine replaced today for the same reason. Now im noticing that its stuck at 100 percent too. I have been using it for about 20 min now and still 100 percent. I guess I will see if it goes down. I wonder if a restore might fix it.

Have you calibrated it? Just use it till it dies then charge it all the way up, see if that fixes it. Worth a shot.

Hah, that's rather interesting. I'm going to play with it (games, books, movies) to see if anything happens. If not I'll probably try a restore. If that doesn't help, I'll just talk to an Apple Genius.

Luckily it's not a huge issue right now.

Hello, everyone, this my first post here. Great info here. I had the same problem yesterday. My iPad was stuck at 100%' would not go down, I streamed a movie on netflix for an hour with the same results, still stuck. I called apple and they told me to restore my iPad, but when the restore was done I had to set my iPad as a new iPad, do not restore from back up. It has been 12 hours since that restore and I fully charged it overnight and have been using for a while and now.I am at 90%' so it seems to have worked. I will keep an eye on it and report my result within the next 24 hours. Have a great day!

In a house...duh!
This happens on my iPhone 3g on occasion. If I shut it down and restart then the battery meter "corrects" itself.

Just my observation. Don't have a clue why it happens.

I'll add another goofy issue to this thread. I was using my iPad wit the screen brightness set to maximum and after a short while the battery meter was at 78%. I turned the brightness down to half way and over the next few hours it went up to 84%. So after some use it gained power... according to the meter anyway.

Oh well, should all be fixed with the next update. I'm assuming it will be out some time soon in the form of a 3.2.x update.

Just turn it off and on again

That will get it unstuck.

Happened to me too.

I think the battery meter is messed up.

I get different percentages if I use ipad info also.

Another goofy brightness-related issue:

Reduce brightness to minimum and within a short time your wifi will disconnect (particularly when coming out of sleep)

Only way to reconnect is to manually force it through "Settings-->wifi --> chose a network", OR, nudge the brightness up from its minimum setting! (found that solution over at apple.com discussions)

I get that on my iPhone. 30-50 minutes use before dropping even 1%.

It could be because the battery accepts a slightly higher charge than its rated capacity, which is common when new.

Therefore, the battery has to use that extra bit of charge plus a bit more before you see any drop in the percentage estimate.

Just my guess.

I would also say it is possible that it is just how the battery is reported by the circuitry in the device. All of my apple device stay at 100% for a while before they show less.
