iPhone 5 went off over night, again.

Hi,

Yesterday I woke up to find for the second time in two weeks my iPhone 5 was completely turned off. Even holding the power button at the top wouldn't turn it on. Initially I checked the charger was switched on because it was at around 10% battery before I went to bed and thought maybe I'd been stupid and not switched it on at the wall.
After realizing it wasn't the charger, I unplugged it and plugged it back in to see if the charging screen would appear. Still nothing.
Then eventually I managed to get it on by holding the power button + the home button to reboot. And was surprised to see it had 100% battery. This made me very confused as to why it turned off overnight.
Had my body-clock not woke me up, I could have been very late for work.

Is this something the iPhone does automatically when the charger is left on too long? I never had this problem before and it's something that's developed recently.
Also, if this helps.. I've suffered from light leak on the top right corner of the screen since I bought it. Just not had time to swap it out yet. Other than that, it's in perfect condition and hasn't been dropped once.

Could it be a bad batch?


Kind Regards

Yep. Same here. Twice in last couple of weeks, once on iOS 6.0, and again on iOS 6.1 (I skipped the .0x incremental updates) - Nothing before that.

I'm not super concerned since I have time left in the first year warranty, and AC+ for the second year, but I did notice. It is a bit unusual.
