iPhone 6s reboots randomly....

I am having same problems. Been looking around the net for solutions before taking it to Apple store. I just received my phone Wednesday and it doesn't matter what app I'm on even Safari the phone locks up. Or it will randomly crash/reboot. Some games too will freeze up. I did a system reset, last resort will be system restore which I would hate to do.

What's the update? Did you get a new phone? I another possible fix. I read where one pushes the buttons for turning the iPhone off till you get the onscreen option for turning off. Turn off, then turn back on. Repeat 5x's. I also let the battery run almost to empty and recharged it. So far yesterday and today no problems with it suddenly freezing and rebooting. I'll see how the week goes. I also removed 2 games from the phone that I normally play. Could be an app specific issue that has bugs that cause the phone to freeze and reboot.

I have the 6+ 128gig that I had shipped to me on the 25 of September. I have had a few issues with reboots, hard reboots at random and freezing up that could only be remedied by a hard shut down due to unresponsiveness of phone. Last night I plugged by phone in to charge. Batter was at 11%. I used the phone at it charged to 37% and then locked it and left it to contiue to charge. When I came back roughly one hour later the screen was unresponsive. Just black. I had to do another restart. I locked up on the black screen with the white apple logo. I did not boot up after twenty minutes so I did another hard shut down and restart and it will not move past black screen and logo. I turned for off for rought two hours and when I tried to restart it again it gave the the "plug phone in" to recharge as it was saying the phoner was dead. I have tried three times to charge the phones battery and it will not move past the recharge message. MY phone is with AT&T and went to store and the manager was quite rude and send if it is after 14 days you must go to Apple get phone replaced. I am at 16 days.

Apple provides all service on iPhones. Take it to an Apple store and they will replace it if it is defective.

I have the same problem. AppleCare has been horrible. I'm going to the apple store today, hoping they'll replace my defective device.

Here's another thread on the same issue.
