This is a natural feature of every smartphone. If you're doing something extremely taxxing on the processor, it may shut off because of overheating. Perfectly normal.

If locked and sat on the coffee table on a cool English morning is too taxing then Apple may want to get new engineers!
 
I think you're right. iOS 9 interacting with some app. The usual suspect would be Facebook.

Kinda agree with this. My 6S+ and wife's 6+ don't have issues, so far, since the upgrade to 9.0.2 and 9.0.1, respectively (knock on wood)
But, I doubt it's related to FB.
 
If you have to hard reset the device to turn it back on, it's software related.

If it was hardware, then the device would actually turn off and a simple power button press would turn it back on....

My 6 with 9.0/9.0.1/9.0.2 hasn't done this at all. My wife's 5s with 9.0/9.0.1 hasn't either. On the other hand, I can remember one time within the past year that my wife's 5s (with iOS 8) has crashed and needed a hard reboot to recover.

The heat issue is explainable: if your phone crashes and doesn't respond to the sleep/wake or home buttons, then it's still running and probably getting hot.

So, I have a question for everybody here who has seen this issue: how often is this happening to you? Is it happening repeatedly or just once? If just once, I can't imagine why this is a thing.
 
This just happened to me not 1 hour ago. Moreover, my 6s Plus wouldn't turn on after repeated attempts with the on/off button. Tried the DFU start-up and it finally powered back on. Strange, slightly frustrating, and concerning...

(PS. I'm also using 9.1 beta 3, so if it software-based, then the bug is still getting through!).

If you're on a 9.1 beta I truly hope you're reporting the issue, so that Apple engineers will have logs to pore over and try to squash the bug before it goes into production.
 
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.

No, but iOS 9 is not buggier than 8 was upon release.

Y'all just have short memories.
 
Apple's way of saying stop taking selfies and checking your texts and associate with people. I'm not mad at this..
 
I've had this happen with my watch a couple of times while opening an app . . . with iOS9 installed on my phone. But . . . not the place to start a watch thread.
 
I'm pretty sure they're having more issues

I'm pretty sure it's not that simple.

Their issues might be increased, but there are numerous factors that come into play. First of all, the devices and software are much more complicated than they were in the past. Second, there are far, far more people using Apple devices than in the past. When you have 35 million products in wild you will see a certain number of issues crop up. When you have upwards of a billion devices in the wild you will see more issues.

Lastly, I do believe that all of this is magnified by the fact that Apple pretty much exists in an aquarium these days. Tim Cook and Jony Ive can't fart without the media reporting on it. Whenever a new product is released a whole herd of click baiters rush out to "test" (read abuse) the device very publicly, and "news" outlets starved for advertising dollars scramble to get the words, Apple, iPhone, iWatch, etc. into headlines on their websites. This is not swipe at MacRumors, BTW. They've been reporting responsibly on all things Apple for many years, before most of the world cared.

Another thing to keep in mind is that this might actually be related to a non-Apple App on the phone. Whenever a new OS is released there are inevitably going to be some apps that have bugs in them, and those apps can cause hanging processes, memory leaks, etc. that will appear to be a systemic issue. I'm confident that this will be a non-issue very shortly. I believe it's software/OS related, and if it's happening to enough people to be reported Apple's engineers will have the bug squashed before long.

It's happening to my iPhone 6S Plus every night now. Plug it in at night wake up in the morning and the phone is unresponsive. Have to hard reset the phone to come back on.
 
by installing a later version of iOS , the device runs slower, frustrating the user into upgrading . Having the ability to downgrade would mean you keeping your device longer . I regret upgrading a number of devices to iOS 8

If you stick to the version of iOS that comes with your device , it wil run smoothly . Problem is, when Apple pushes these updates , and makes them so easy to install, there is no warning that your decide will be slower and suffer from lag.
Maybe because that's not true. Never seen lag or slowdowns after a software update on my iDevices

it's the 7000 series aluminum that creates overheat and interference.
What ? Aluminum dissipates heat ...

I think you're right. iOS 9 interacting with some app. The usual suspect would be Facebook.
I don't know about Facebook, since I'm not using it ....
 
Software issue.
Probably, but not related to iOS 9 only, since not everyone are experiencing this...
Every iPhone comes with a one year manufacturer's warranty. Until some time in September 2016, every single iPhone 6s in the world will be covered by manufacturer's warranty. If your iPhone 6s doesn't work, take it back to the store and have the problem fixed.
Two years for us Europeans...
I wonder which CPU is being used? TSMC or Samsung?
Stop this paranoia please ! We are speaking also about iPhone 5S, iPhone 6 and others....

No, but iOS 9 is not buggier than 8 was upon release.

Y'all just have short memories.

Correct. The whining was strong at the time of iOS 8 release....
Today iOS 8 was the "perfect iOS "

My iPad Air 2 did this a couple of times. It was running iOS 8. So did my iPod Touch 5. It may have been running iOS 7. Not seeing this problem on iOS 9.

....

Really? That is not my experience. Updating my iPad 2 to iOS 8 was the death knell for my totally clean iPad 2 i.e. nothing kept on the device apart from the generic apps. Slowed it down to the point I could have smashed it (32 gig Wifi only).

As a result I sold the device on and used the cash to purchase an Xperia tablet - runs like a dream. With Sony, 'everything just works'. ;)
 
It's times like this that make me wonder how Apple can get away with preventing us from reverting to earlier versions of iOS.

When I bought my iPhone 5s, it shipped with iOS 7. I updated my phone to iOS 9, which I feel has made the phone slower. What purpose does it serve for Apple to prevent me from reinstalling iOS 7 so the phone is just the same as how it was when I bought it?

Apple doesn't do this with OSX on Macs. I can reinstall OSX Lion on my MacBook Air 2011 any time I feel like it. Why is iOS treated differently?

What you say makes perfect sense.

But, as others here will tell you, the problem is not Apple.

The problem is YOU. ;)
 
I just experienced it now. My 6s suddenly shutdown and when i tried to press the power and home buttom it turned on.

Understood, but an iPad 2 is very old hardware ... I wouldn't have it updated to iOS 8 since the beginning

You want Tim gone? Better start with yourself by refusing to buy Apple products so you don't contribute to their coffers. Then, good luck convincing the millions of happy owners of Apple products that they're actually not happy with their products, and Tim Cook is the reason for that.

I wish you the best. It's a tough task, but tenacity knows no bounds.
