My iPhone 6 switched off on me a few times, and so far it has happened once to my 6S.

However, whereas the 6 would restart again as soon as I pressed the power button, the incident with the 6S this week was different.

Firstly, it wouldn't power back up again when I pressed the power button.

Secondly, my Apple Watch didn't show that it had lost contact with the phone, and the watch apps continued to function normally, which they cannot do unless the phone is on.

Thirdly, the phone only booted after I reset it by holding down the power and home buttons simultaneously.

It seems to me that although the phone was completely unresponsive and seemed to have switched itself off, it was actually still on and it was only the display that had stopped working.

The 6S was on 9.0.1 when it happened.

I had the same problem a couple years ago with my iPhone 5 running iOS 6. It happened about once a month. It was solved with iOS 7. It's definitely a software issue. No reason to swap phones.
 
And I thought it was my issue. When I got my first iPhone 6s (9.0.1), it would do this, and I thought it was a battery\hardware issue so I ran (not walked) into the Apple Store and got it swapped. Now having restored from the same backup and using the same iOS\Hardware, no issues, so clearly there's a hardware issue at play here. Glad I swapped mine out.
 
I had this issue on my iPhone 6 while I was running the public beta a few weeks back, it would happen almost every day. I have not had the issue on my 6S Plus since I received it, on iOS 9, 9.0.1, or 9.0.2. So most likely an iOS 9 issue, not a 6S issue.

I have the 6S Plus, running 9.1 (beta) and this has happened to me twice. Had to hard reboot to get functional again. I agree, probably a software bug.
 
Had this happen a few times with my 6 a couple of months ago when I first activated iCloud photo, and it had to take a couple of days to completely sync the library. Usually happened when the battery was on the low-ish side - but not so low that I'd normally worry about it. I attributed it to an iCloud glitch. Stopped happening a few days later, and that 6 and now my 6s have been fine.

Wow can those 'geniuses' now instantly fix operating system bugs? These guys are underpaid!
 
LOL. But still there're people who will deny that Apple software quality has slipped and it's more buggy than it ever was in the history of iOS and OS X.
Tim should fire himself.

Had it happen to my 6S Plus (128G, Verizon) on 9.0.1 a few days ago. Judging by the other responses, this seems to be an iOS 9 issue, not a device-specific issue.

Hasn't happened since. On 9.0.2 currently.
 
I had this happen to me on the first day. Wasn't sure if I turned it off by mistake.

I actually thought it was because I was using a 6 leather case on a 6s and it may have been a bit to tight to where if it maybe shifted just a fraction of mm it may have pushed down the power button and then it just acted weird. Anyways, I posted that my phone shut off on day one of launch and my thread didn't even get a reply. Now it is a headline lol how funny. Hope it is a software thing
 
Not sure if Apple is having more issues or if it's the matter of every single thing that happens gets reported on.

More complex os always has more possible variables when rolled out to the millions of users with millions of cellular networks, router configurations, apps in the background and

Apple has been more responsive this year with more frequent updates. Could wait a month and give 1 update, but definitely quicker to give what they got in terms of adjustments to the 0.01% who reveal the needs.

I am part of betas, because nearly never an issue, it's easy for me to cope, and I like to make the final rollout to normal customers just that extra bit super smoothier :)
 
My wife's 5s with 9.0.2 would not wake first thing in the morning. Did a sleep/wake button & home button reset to fix.

My 5s also with 9.0.2 is fine.
