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

This just happened to me this morning with my iPhone 6. It never happened before. There's definitely something buggy with the latest software upgrade. I had to hold the Home and Power buttons down for almost 20 seconds and it revived itself. Originally the phone had a 35% charge and was lieing on my bed. I went back to it 5 minutes later and it had turned itself off and I could not get it to turn back on. When I finally did do a hard reset, the charge went down to 29%. I certainly hope this doesn't happen again and that Apple fixes this problem.

Just happened to me too. Came back at 62%. As Gail says, ensure you hold both buttons for 30 secs. It does not hard reset, just soft reset.

first time it's done that on my iPhone6

This has now happened to my iPhone 6 for the third time in a month. The first two times it happened, the reset mentioned here did not work for me. Nor did connecting to iTunes. While dead (and plugged it), the phone will ring if someone calls me, but I get the Temperature/overheating message when I try to answer it, even though the phone was not hot (it was actually cool to the touch, being on in an overly air conditioned office). Both times, after sitting overnight (not plugged in or connected to iTunes), when I tried again to charge it in the morning, it mysteriously started to work again. I had to wait until it reached at least 10% charge before I could turn the phone on. Now that this has happened for the third time, I finally made an appointment at the Genius Bar for this weekend.

Add me to the list... my iPhone 6 was working fine this morning (using at as my alarm clock), when I got to work the phone was dead. I tried turning it on, but it didn't want to turn on. I thought maybe the battery died even though it was 60% charged this morning. I plugged it on to charge and nothing. Tried a hard reset, that didn't work... at least not at first. After the 3rd hard reset attempts it finally turned on at 56% charge. I'll keep an eye on this...

I also had this happen to me today. It was 100% charged. I looked up something. Had breakfast, came back and it was dead. Researched and followed instructions about holding down the 2 buttons for 30 seconds. Then an image popped up telling me to hook it up to itunes When I plugged it into my computer my home screen came back but my phone battery showed 57%, thankfully it charged and is working now.

This happened to me and it never came back! So make sure you back it up to the cloud or iTunes as often as you can to save any new pics. I didn't have my cloud set up correctly and lost 3 mo of my baby's pics and videos. NOT HAPPY. Get it checked out.

..same here, phone is charged but just died super suddenly

holding down the 2 buttons for 30 seconds

this worked for me.

BRAND NEW 6 and I've got the same problem. how many people does this have to happen to before apple will correct? when people rely on their phones, this is unacceptable. really apple? and the phone won't hold our wifi and sometimes doesn't even see it?

Update to my prior post (Jun 22, 2015 6:09 PM): I could not reset my phone using techniques posted by others on this string. Could not get the phone to boot past the Apple logo. Phone was examined by Apple technician at the Genius bar with same results. They replaced my phone which was still under warranty

Past week or so my phone is having the same problem, turns off even though the battery was almost full (70-80%), did the hard reset and worked for me, but last night the phone just switched off, i tried 10-20 sec (power+home button) and it tries to start up 1-2 sec and then just dies . Also it just shows some back-light as if starting up when charging ( that's about it ). i am taking it to apple store and will update on what they have to say.

No there's not.

Who are "They?" It's certainly not the IOS update.

this is happening to my 6 plus, too. resetting doesn't work for me. and now it's rebooting itself every 5-10 minutes with a black back-light and nothing else on the screen while unplugged

Took phone to genius bar, they replaced the phone (0$ - it was still under warranty ), the associate said that hardware related - internal logic is failing, i didn't ask for more details.
