Don't swap at Genius bar. This is a software issue. It is happening to a wide range of phones since iOS 9. If you do want the 6 Plus and are in your 14 day window, that you can do, but have the original box and all accessories with you.

Gotcha, think I'll just keep this one. Thanks!
 
I had this happen a couple times on my 6S Plus. The last time it happened, the screen was dark and home button unresponsive, but I found I was able to pull down the Today/Notification screen and pull up the Command Center. Hit a few notifications and was able to get the phone to respond. Maybe another issue entirely, but worth checking out if you find your phone doesn't seem to be responding.

Issue:
Many users have found out that their iPhone 6S, 6S+ (some 6) turns off by itself, even when left unattended. It is fixed by forcing a restart of holding the home and power button for 10 seconds. Had this issue? Read below. I am sending this data to Apple's engineering team once we collect enough data.

iOS public release users:
Please post your model, OS, and actions before the problem occurred.

iOS beta users:
Please post the same info as above, but also report it through Apple's bug report.

Sample Diagnostics:
iPhone 6S 64 GB Gold
iOS 9.01

1. Plugged iPhone 6S to USB on Windows PC
2. Changed region to US where iOS restarted itself automatically
3. I didn't see the Apple News app so I restarted manually with the power button
4. I checked a few minutes later and the home button nor power button could wake the device
5. I restarted the device holding the home and power button for 10 seconds

At first I thought it was a battery issue when this happened to me. 6S 128GB SG iOS 9.1 PB 2. Attempted to charge the phone but there was no apparent change after half an hour. As others have reported, the phone was unresponsive until a hard reset. Curiously, the battery percentage showed an increase from 10% to over 50% within a few minutes. No issues since this happened a few days ago and battery life is on par with my 6.
 
I can't say I have witnessed this specific issue. However, there have been times when I want to unlock my 6S+, and I am prompted to key in my passcode, which suggests that my phone had recently rebooted itself. Does it count?

Same issue here. Happened a couple of times since I received my phone Friday, and one of those times was on iOS 9.0.2 (on an iPhone 6S Plus). Tried restoring with 9.0.2, hoping it won't occur again.

Edit: TSMC chip

The A9 chip theory
Not to get suspicious yet but the poll so far has 100 samples and has almost an exact 40:60 ratio of people who experienced this issue to people who haven't. Guess what else has a 40:60 ratio? Samsung to TSMC A9 chips.
...
Anyways, we just need more information. I am updating a public file soon to aggregate everyone's data.

For those of you who can run Xcode 7 (thus, no $99 developer enrollment needed to install apps from source code), this github repository has source code for a safe app that will tell you which A9 your iPhone 6s is using: https://github.com/WDUK/A9ChipSource

Had that happen this morning. Thought it was odd.

Phone has "locked up" once a day before. Non-responsive to any buttons, had to power+home it to resurrect.

Edit: iPhone 6S 128GB, iOS 9.0.1 (now 9.0.2 as of tonight -- we'll see!)
 
Literally just happened to me.

iPhone 6S 128GB Rose Gold
Happening with iOS 9.0.2, 9.0.1 and 9.0
Hard reset by holding lock and home button for 10 seconds fixes it for me.

UPDATE: s8003 TSMC chip

Happened a couple times and most of the time its happened while its been plugged into the power. I haven't really noticed it turn off without it being plugged in. I have a dock at work so i guess since its always plugged in this could possibly be irrelevant.

When it first happened i noticed that the Touch ID was extremely hot

I've had it happen once.

iOS - 9.1 Beta 3
iPhone - 6s 64GB Space Grey
Carrier - Sprint
A9 Processor - TMSC

I was in Safari reading a webpage and the phone just froze. It then just went black without notice. Turned on only after the manual force startup as described.

I've had this issue about 3 times, always when i've not been using the phone for several times. interestingly, twice its happened when I was eating lunch with my phone faced screen down, when I picked it up at the end it was dead.
 
I have an iPhone 6s Plus 128GB week 38 (Factory F2) and TSMC A9 chip and I've never had the shutting off bug; (or the bad screen issues). I've run iOS 9.0, 9.0.1 9.0.2 and 9.1 betas 1,2 and now 3.
 
My wife has had this issue on her Verizon Silver 64GB iPhone 6S. I restored it Monday from backup of her Verizon Gold 64GB iPhone 5S. That phone was in turn (two years ago) copied over from an iPhone 4 32GB Verizon phone.

It seems to turn off while in use. Only way to get it back is to hold down both buttons.
 
I first voted "no" but then I thought about it and realized that this happened to me yesterday! iPhone 6s 64GB Verizon iOS 9.0.1 (updating to 9.0.2 rn). don't recall it being hot or whether or not I had it face down. had to hold power and home to force restart.

Edit: I had it sitting on my desk sleeping (not charging). tried to wake it to show someone something but it wouldn't turn on. I just dismissed it as iPhone quirkiness since being on betas for so long (wasn't on beta when this happened) had me accustomed to random things like this

iPhone 6s 64gb. 9.0.1 It seems identical but the screen was not black. The power button would put it into shutdown mode but I couldn't swipe to turn it off. Plugging into power would exit shutdown mode. A hard reset fixed it. Maybe it's a slightly different problem or maybe it's the same problem but my screen didn't go black.

I've experienced this too with my 6s and old 5s so I'm not sure this is the same issue that's being discussed here
 
A couple days ago my 5c's home button refused to work for 5 minutes, then magically started working again. I couldn't reset it, and powering off didn't fix the problem.
 
This happened to me yesterday. I set the phone down for awhile (maybe an hour) to do some work and when I picked it up it was unresponsive. It had plenty of charge left on it (probably 75% charged). I tried to turn it on, and no response. I plugged it in to charge and no response. The interesting thing is that my Apple Watch was still connected to it. I tried to ping it with my watch but no sound played. I was only able to get it going again when I pressed the home screen button and the side button for a full 10 seconds. I have a 6S on 9.0.1. I did not notice any excess heat.
 
Just had it happen with my 64 gb 6s plus. No amount of button pressing or waiting would make it wake up.

6s Plus, 64GB, black, Running Beta 9.1 v2 when it happened. Was charging it overnight and when I woke up it wouldn't turn on. Just happened the once.
 
Wow, just happened to me.
I didn't really think much of it, then come to macrumors and it's the top article.

So yes, it's happened to me on a 6s Plus running 9.1 beta2
