iphone 6 automatically restarting?

Has anyone noticed that their iphone 6 will power down and restart on it's own? I thought it happened twice before, but just saw it happen.


I am not referring to just going to a dark screen. I mean going to a black screen, the white apple logo showing up, and then requiring a non-Touch ID login?


I thought it may have been the apple case for the iphone, but I did not swipe to power off.


Very strange.


This happened before and after update from ios 8 to ios 8.02.

MIne just did that a few minutes ago. I was on the phone too. It didn't even hang up. It went black and then the apple logo appeared. This is a replacement I got 2 days ago too! First one was getting super hot upon opening any application. If it happens again I guess its another hour wait at the Apple Store for yet ANOTHER replacement!

I have had this same problem - he has been happening consistently since I got the phone (2-3 times a day) - the ios has been updated 8.0.1 and then 8.0.2 still occurs. It happens on phone calls as well as when using apps, even when it is just sitting unused on my desk - I notice something unique as well about the restart there is a complete blue screen and then the apple logo and then a complete red screen and then apple logo and back to the start screen I have not tried a restore, but may if it continues. I also notice that it has a bit of trouble handing off from wifi to 4g data connection. When leaving a strong wifi signal the status bars shows it still connected a "one bar" long after the signal should be out of range - as a result when trying to use the phone on the internet it says it cannot connect even though it should have switched over to a sufficient 4g connection.

I have thought of taking it back to the apple store but both of these issues (especially the intermittent restart) are so hard to reproduce.

I tried a bunch of different things. Ran the battery down to 0%. Reset and restored from iCloud, and from my mac. Kept happening, when I was charging and when it was not. With bluetooth on and w/o. Took it to Apple Store and they replaced without question. Genius wasn't sure what would be causing it either but said it was best to replace.


Thank you for the suggestions and for letting me know I wasn't the only one.

Had the same, 128 GB version. On the Internet I red that the 128 GB and some 64 GB versions have TLC NAND memory instead of MLC, which is less fault tolerant. As Apple support denied the problem, I returned the phone within 2 weeks. Would like to know how we can see the type of memory, as I understood that Apple has changed the production and is now using MLC memory for all iPhone 6 versions, not the TLC memory.

This must happen almost 8 times every day for me as I'm using the phone. Incredibly annoying as I could be driving and all of a sudden I have to reenter my destination and navigation and music on the road. On a 128 GB iPhone 6 with TLC NAND. Wondering if it's only TLC NAND devices with this issue since I haven't heard from people with MLC reporting this issue.

Here's how you can check your phone is TLC or MLC, install "IOKitBrowser" from here: (no jailbreak required so this doesn't against the apple's rule).

after install search for "device characteristics", and keep tapping the result until you see something like this:

Look for "default bits per cell", 2 means you got a MLC phone and you are fine, 3 means you got a TLC phone so you may probably experience some random reboot problem and keyboard missing etc issues. That really depends, according to my test, I have the random reboot problem when I used around 50% (around 600+ apps) of 128Gb (on two iPhone 6+s), and have keyboard issue, missing character issues and bunch of issues after I installed around 800+ apps. (10-20Gb left and crashes on both two 6+). I can say it's a very general issues since I only got two TLC phone, and haven't tested MLC iPhones yet, but it is possible that all the TLC have this risk till you install some amount of apps or used some amount of storage.

Announcement for today:

OK, I just get back to the store again, and they give another replacement for free, but I have to wait till my new iPhone send from somewhere else to the store. I guess I may going to receive a new iPhone with MLC instead of TLC, since apple has already banned the TLC this November. Guys the only way to solve this problem is bringing your iPhone right into the store and ask for help ASAP, those people from apple store are really nice guys, I can tell they really want to solve the problem as urgent as you do, and also the only way to send those problem iPhones to Apple.
