Related to the charging flex cable port, Solved this simply using an original salvaged charging flex cable, 100% fixed. Some aftermarket charging flex cable aren’t working on iOS 13.x, They’re messing with something related to the thermal system, and forcing a kernel panic. (PS=The phone will keep restarting without any charging port,too).

Your reply saved my phone!


Hope my experience + your solution can help others...


Had some water spill onto the phone while charging which was discovered too late. Phone would no longer turn on, and the USB port looked damaged. Removed the screen and discovered that water traveled into the bottom of the phone so I removed major components from the bottom up until I could be sure all was dry and then let sit 48 hrs to be sure.


Phone finally powered back on, but went to recovery mode and requested I plug into itunes. itunes could not resinstall iOS and kept giving me 4013 error.


At the store, Apple said my phone was gone and to buy a new one - "nothing they could so." A local repair shop said $150, and they could replace the motherboard, but couldn't guarantee anything. FYI, replacing just the motherboard also means FaceID stops working as the camera and board are tied together.


However, since the source of the initial issues was the charging port, I bought a new USB flex and lo and behold, Itunes was able to reinstall the iOS! After patting myself on the back for the $8 repair, I reassembled the phone but discovered it powering off every 3 minutes to the dot. Spent hours trying to diagnose, and ran into many posts about the 3 minute restatrt, but no solutions. Much was attributed to a bad motherboard. Finally stumbled upon this lone reply which suggested my "new" USB flex was actually bad, which was further supported by iOS diagnostics error log showing me that every 180 seconds it was shutting down because it was getting a thermalmonitor error.


Long story short, another new $12 USB flex later from Amazon, and my iphone X is now completely operational.

I had done no damage to the phone, and I had only had it for about a week. I made an appointment at a local apple store the same day & they replaced it on the spot since my phone was still under warranty & they had the same phone in stock. The issue started happening the morning after my phone had updated to IOS 13.3.1, so I thought that this might have been related to the update, but the apple store employee told me it was likely a hardware issue. Since your phone is only 3 months old, it is still under warranty I think, and if they find that there is no other solution (reset won’t solve, etc) they will probably replace it for you as well

(btw you might want to ask them to check the analytic data to see the panic log- they did this for me anyway, but the person on this post said theirs was not checked. Once the employee saw the panic log come up in my phone, he immediately told me they were going to replace it.)

I experience the same problem with my iPad Pro.

I went to the Apple Store for repairing but they told me that there is nothing to do but changing the whole board even if it is not cheap and without any sense for economic reasons ( it started happening 4 months after the official warranty expired). I use it in my University courses and I found that the problem arises only when the iPad is cold so it seems it is a problem of the temperature sensor in cold conditions. The solution I found is to play a video for half an hour before using it in class and when it is in temperature the reset problem disappear.

Hope it can help You.

Hello mosa144,


Welcome to the Apple Support Communities. It sounds like the iPhone's constantly restarting. I'll do what I can to help.


Be sure to follow the steps mentioned here: If your iOS device restarts or displays the Apple logo or a spinning gear unexpectedly


If you're still having issues, it might be related to hardware. Look into the service options here: iPhone Repair - Official Apple Support


Thanks and have a great day.

I have the same problem on my iPad mini4. It was perfectly fine until I upgraded the OS to v12. After that, it has never worked correctly and constantly restarts. This IS a software issue and caused by Apple. Apple wants more money. They have written code to cause this problem and their solution is to buy a new battery. This is wrong! It IS a software issue. Apple has lawsuits against them related to this.
