I have a different problem that I know is not just specific to my phone. We have three iPhones in our house: two 5's and one 5s. Over the past 6 months every few weeks they glitch. What happens is that at exactly midnight eastern time all three phones start showing the lock screen for two seconds, followed by a second of a black screen, followed by five seconds of the Apple logo on a white background. During this time the phone is running. When on the lock screen you can actually swipe left and start entering your unlock code, but you will get interrupted. This usually goes on for at least 6 hours. Hard resetting the phone does not fix it: you just boot to the same state. Restoring from a backup does fix it. And seems to be the recommended solution on the Apple forums.

This is a huge problem. First, it slights up the whole room and drains the battery. If not on the charger, the phone will die and our alarms will not go off. If on the charger, the phone will also keep buzzing. BTW, we use standard Apple cables and chargers. Restoring from backup takes a long time and I do not wish to do that for three phones in the middle of the night.

I really hope this new update also fixes this problem. Has anyone else encountered this, and if so, have you had luck talking to Apple about it?

Edit: none of the phones are jailbroken or have ever been. The home network is not special in any way other than having IPv6. My strong suspicion is that this has something to do with automatic app updates + a buggy app, but it seems like a pretty bad OS-level bug to allow this type of behavior.
