Read this post while searching for an answer. Though late... it may help someone. One of the reason for this would be a zero charge in the battery itself. Try leaving the charging on for a good 10-15 minutes and it may stop rebooting and start charging itself. Hope this helps. It sure did work for me. Cheers

It is a faulty battery and you need to replace with new tested battery

"Finally, finally! I've got the real answer! After ""fighting"" with my iPhone 5s for the better part of 6 months, I've got the answer to why my iPhone always reboots overnight while charging, and happens several times during the day, if it's plugged in. I have tried software fixes, resetting everything. I've had a new battery installed. All this, to no avail.

You ready for this? it was some foreign particulate matter in the charging (lighting) port, and not lint. I had taken it to the Apple Genius and they said they cleaned out the port although they said it wasn't all that dirty. It still would do these random reboots. I then took it to a small Mom and Pop computer store that specializes in Macs and iPhones....in a second, he said, there's something like graphite in the port; he felt the irregularity with some sharp tweezers; he said, it wasn't ""flush"". I thought he'd damage the port, but he assured me these ports are heartier than one thinks. He removed (scraped out) the little piece caught in the back of the port, and lo! and behold! No more reboots. So, yah have to find someone who really knows the iPhone innards. Ahhhh, life is good again. :-)"

"Hi guys,

Today I had an iPhone 6 with the similar issues, as battery replaced then after around 5-6 days the phone started to rebooting itself. Fact, the customer kept dropping as several damages were on all corners. Tried the usual stuff, new battery, minimum config, etc.

After disconnect and reconnect the battery sometimes its booting up but the problem starts again soon. During a restore, gets iTunes 9 error but without the screen I was able to restore it successfully. The rebooting issue still happened. My previous experiences shows (or i just got a feeling) the NAND chip has some “broken legs”

To replace the NAND on this old, worthy device just no way, not worth for me :)

So I applied 150 Celsius on the NAND for about 3-5 minutes than increased the temperature very slowly to 210 Celsius for 15-20 sec, than slowly increase to 300 degree and kept like that for 15-20 seconds and let it cool back.

The phone works fine now, for 20 hours without a reboot. I know its temporary repair but I will see how long it will live :D

and update this post as soon the problem come back…

update: came back after 4 days… (did not tried higher degree)"
