PROBLEM:
Everyone who has an iPad 3 knows that it takes substantially longer to charge than the iPad 2, and, if you are unfortunate, the device can drain the battery quite fast. Some people have been reporting accelerated battery drain, and some have not.
When I first purchased the iPad 3 and restored it from my backup, the battery was draining very rapidly. When it was plugged in and I was merely using safari at mid brightness, I would still LOSE 1 or 2% per hour on my battery.
Finally, I got fed up with the device and restored it. As soon as I did, my battery started charging more than twice as fast as it was before. While I was happy with the change, I still wanted to know exactly what was drawing so much battery life. Alas, without the problem reoccurring, I would be unable to do any testing.
Yesterday, however, my battery life dropped again dramatically. There was no way that I was going to restore every time this issue arose, so I decided I would do some power draw measurements on different processes to find out exactly what was sucking my battery faster than it could charge.
I ran a draw test on the amount of current that was being used by open processes, and found something that astounded me: even though the app was closed (closed out of the multitasking menu as well), Facetime was STILL drawing between -100mA and -500mA of power, with the -500mA being more frequent of the two. I switched it off, and my battery life returned to normal.
SOLUTION:
Go into your iPad's settings and disable Facetime completely. For some reason, it's drawing a tremendous amount of power even when the app is closed. I don't know why it does this, but hopefully the battery drain for Facetime is a bit less significant with the next patch.
