iOS10.1 bug or coincidental hardware fault

[vexorg]

My daughter updated her iPhone 6S to 10.1, since then she's had the phone shut off randomly as if it has no battery power left. The battery has been 80 to 90% sometimes when this has happened.

Worse still is that it will not power back on unless a charger is connected to it, and when it turns back on then it is back to the same charge level. And all normal again.

We've spoken to apple and they have run a remote diagnostic on the phone, no faults found. We need to get booked int a genius bar now. It'll be a few weeks before we can do so. In the mean time, does anyone know of a bug or setting in iOS 10.1 that could cause this?

I'd be trying a full fresh restore via iTunes....its a good chance thats what the Apple Genius will say anyway.

See the other thread. I've had this too for 5/6 weeks. Been on to Apple support to see what the issue is. I've restored and set up as new several times. I have an appointment at the Genius Bar this Saturday so will update here after.
The senior level support guy said there was a fault with my phone, but the hardware and battery diagnostics showed no issues. He said (and I quote)
" notes have been made on your case number so please go to the Apple Store and I promise you will be pleased with the outcome". I asked- "will they replace it for free?" and he repeated " I promise u will be happy"
Not sure what that means, but his answer left me thinking they know something is wrong but won't elaborate.
The issues still persists on 10.2 beta just for the record.

We did try to restore from an older backup and fell foul of the corrupted backup problem. After an hour or so of restoring iTunes pops up with "some file is corrupt and the phone cannot be restored" type message. That too seems common and apple don't care if something goes wrong during the backup.

We tried to set it up from new again by going into recovery mode and connecting to iTunes. Oddly this did not fully wipe the phone, the photos are gone, but the "memories" still has some photos shown. I'm not convinced if that is a true clean install of iOS again.
