iPhone 6 plus sudden shut off and won't turn on.

You should try this it seems to work for everyone: hold BOTH home and power buttons down for up to 30 seconds TOGETHER . Should start up.

PS bizzarre as it might sound I may have had the phone linked to my laptop via a USB at the same time. NO idea why this should have any effect but when the phone started up it also synchronised ... Good luck

So, it's not OK for Philly_Phan to respond to the poster, but it's OK for you to comment on a post that was done over a year ago, without providing any of the information that might help us to help you? If you want help here, then randomly commenting on other posts in the thread for the sole purpose of criticizing, and not providing any information as to what specific issues you are having, is not going to achieve that.

What iPhone are you using? What iOS are you running? What specific issues are you having?

Several different issues have been discussed in this forum, so not sure which one you think "Apple should address".

So, again, please state what your specific issue is, what iOS you are running, whether you have jailbroken your phone, and what, if any non-iTunes Store apps you are running on the device.

This does not seem to be a warranty issue. It seems to be an apple software issue? I will be going to Apple store in the morning and my Iphone 6 is off warranty and never had any issue untill I attempted to update onh iTunes. Mine even went off and to red battery indicator while pluged into itunes and iTunes was waiting for the iphone to respond in order to continue the update. Now I plug it in for hours and the charge does not go up much. There is an issue with the Apple software sounds like an issue in the programming of the apple power center. I also know of people who all of a sudden their iphones are getting very hot and they never had this upto the time of the update. Apple check out your update and replace every iphone you caused this fault to occure. I think the heating is burning the power control center out.

I just realized that you had specified that the device you were referring to was a 6s, not the 6 Plus in the title. Check to see if it qualifies for this program:

My last two have been "accidental", but that is because I chose the wrong option.

Anyway, you may want to take a look at this:

Thanks, but yes, I have done that. Twice actually. Roughly 6 months apart. My phone is no longer under warranty so I'm thinking I need to bite the bullet and upgrade.

That would have been helpful to know ahead of time. If you have a plain ol' iPhone 6, then unfortunately, you are not even eligible for an OOW replacement 😟.

Looks like an upgrade may be the way to go unless you want to look into getting the battery replaced (which is an unknown amount, apparently): iPhone Battery & Power - Official Apple Support

Worked for me. Yippee!!

I just had this happen to me while I was in school and still won't turn on tried everything (iPhone 6)

nothing didn't work

Sorry about that. I think it took me a few try and persistence paid off - for me at least. I don't have any better ideas.

If you have an issue that you would like help with, then please tell us what it is. This is an 8-page thread, and we are not going to try to figure out which of the several types of issues you might be having.

Same thing just happened to my daughter's iPhone 6s purchased new March 2016. No drops, no water damage. Held down reset buttons beyond 30 sec, tried 3 chargers, Verizon store couldn't revive it. It had been on and used for a couple hours earlier in the day, no problem. What the heck, Apple? Pay premium price, but dependability is going downhill. Still under Apple warranty so will be returning it. Nevertheless, pretty annoying. My iPhone 5, two+ yrs old, has been a good workhorse. Now makes me feel I should keep it awhile longer, though I'd like a better camera and display. Are we just supposed to be happy these days that our phones don't burst into flames?

Apple is not here - this is a user to user technical support forum. When you say you held the "reset" buttons do you mean the Home and Power buttons at the same time? Did the Apple appear? Are you certain that the device is charged?

It is possible that you got a device that had a manufacturing flaw, ergo the warranty. It happens. But if it was a case of "dependability", then millions of people would be flooding the internet and this forum.

I agree, it is annoying and a major bummer, but the good news is that it will be replaced.

I have just read through 12 pages of threads. I have had this phone for over a year. Have only had this problem for the last week. First, it would shut off with 30% power. Now, it shuts off with 88%. Goes to dark gray screen. Since I am at home, I can plug it in to charge. Shows regular drained battery picture, restarts, and shows 88% power again.

I turned off the app refresh button, as suggested. Thought it helped, but it still shuts down for no reason.

Am I hearing correctly from all of these replies that I should do a reset to factory setting as a new phone? Some have said it is a hardware problem.

Could it be latest upgrade? I don't recall the home button getting hot.

And I live up in the mountains nowhere near an Apple Store.
