    I know it's a beta, just wondering if anyone else has seen similar behaviour on their iOS 6 devices. Since this I have gone back to 5.1.1.

    My iPhone was at 100% when I went to bed last night, woke up and it was at 92%, so 8% lost overnight doing nothing.

    I used the phone to listen to music and browse the web on the train to work, and upon getting to work the battery was down to 79%.

    I got to work at 9:30am and at 11am my phone lit up and told me I had 10% battery left. The phone was hot to touch, and the remaining 10% went within 5 minutes. There was nothing running in the background, the display was off the whole time, no location services running.

    As I said, I'm back on iOS 5.1.1 now but it was pretty odd as I've never seen this on any of the betas before.

    Seen this before. Wipe and set up as a new phone to fix.

    Keep in mind that the battery percentage is essentially just an estimate. For example; at times it could drop faster from 100 to 90% than it would from 10-0% (or from 40 to 30% vs. 60 to 50% etc.)

    This is also one of the reasons Apple recommends doing a complete charge cycle once a month ( to help calibrate the battery meter.

    From my personal experience, this complete discharge/recharge does seem help the battery percentage estimates level out.

    (I have no source on this other than random web searches like this:

    OP: I had the same issue. I refused to set up as a new phone, so back to 5.1.1 I went... It sucks cause I really thought it was stable enough to use on my primary phone (excluding battery life) Also, iTunes Match wiped my music after I synced and it forces you to download each song one by one (takes forever even with only 8-10 gb of music). Setting up as new phone works I'm sure, so best of luck if you go that route!
