iPhone 6 Plus keeps rebooting after battery replacement
So I just received my iFixit kit today and replaced my battery, but the phone itself keeps rebooting after that...
What can I do to solve this issue?
Please help! Thanks!
It is quite possibly a defective battery which is easily tested. If your old battery was still functional plug it in and make sure the device still powers on. If your old battery was not functional then you can plug your lightning cable into the phone with no battery installed to confirm the device will power up. If it does not you likely have some other issues and the battery may not be the culprit.
If you do have to return the battery contact the ifixit team at the links found on this page.
Is it doing it while unplugged from a charger? Have you tried turning it on with it plugged in to a wall charger and see if the apple logo goes off immediately after unplugging the charging cable?
Could be a bad battery, try replugging the battery.
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. :-)
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
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)
Actually, I’ve had this problem and fixed it. Its the cable connectors that attach the screen to the base of the phone. One of these is not connected properly, or has a bad connection, probably from being touched by human hands and has some oils from skin blocking the connection. All you have to do it take them off, clean them with alcohol, then reconnect them—just making sure they are all firmly pressed down. Check to make sure this worked before closing phone back up by simply turning it on.
If the problem persists…
There are two other things you can try. Another connection that causes this problem is the front facing camera and the proximity sensor assembly. You can try to remove and clean connections.
Finally, you can plug phone into charging cord, turn it on, then plug into computer with itunes installed (this will force reset). The blinking apple will most likely continue for for a while, but just leave plugged in, and surprisingly it will eventually reset, as long as all the connections have been cleaned of any oils from your hands.
I have had this problem on two different models I fixed, and these solutions worked both times; unfortunately, one of them had the problem resurface later, which means the board connectors were damaged when the screen was originally taken off and then entire board will have to be replaced.
Helpful hint. When reconnecting any cables, try not to press in the center. Press from one end, then other end. This will prevent them from being damaged.
Mine kept restarting and wouldn’t fully charge after battery replacement. I opened it back up and reseated the battery cable. Fine now.
