I have an interesting repair, it’s an iPhone 11 that reboots every 2-3 minutes. I replaced the charging port and it still does it. Upon just loosely connecting the old port it works fine, is there a part like the Taptic Engine, lower speaker etc that could be shorting it out? I’ll attach a picture of how I’ve got it working right now. If I install it, it’ll go back to rebooting.
This is a pretty common occurrence, believe it or not. If you have replaced the charging port assembly, either the one you received is faulty. Which is also not uncommon. Third party charge port assemblies are notoriously shoddy. It’s one of the parts I recommend to be get the premium option, or an original Apple one pulled from an iPhone, if possible. Or, it’s the power button flex cable. Which is the other most common culprit for this in the iPhone 11. I would have a look at iPhone Keeps Restarting, specifically the Missing Sensor Data section. On the off chance it’s crashing for some other reason , the list of iPhone Kernel Panics could also help (it’s a work in progress).
