iPhone SE (1st gen) doesn't charge + randomly reboots
Hi there! I got an iPhone SE (1st gen) that wouldn’t turn on. (Showed the Apple logo and immediately turned off again.) On opening it, I discovered that a third party battery had been installed. (Branded “LTZGO” and labelled as “high capacity, 1800mAH”.)
I switched out the battery and tried an iFixit model as well as an old original Apple battery. The iPhone boots fine now and everything works, but:
- When plugged in it shows “charging” but the battery percentage doesn’t change.
- The phone randomly reboots after a couple of minutes of use.
It’s got iOS 13.5 installed.
Is there anything I can try to narrow down the problem further? Is this salvageable? Or does it sound like a logic board problem?
Any help is greatly appreciated!
