Chosen Solution
Hello. I just got a iPhone SE with everything original except display was touch irresponding on left side. So i just replaced the display with a new one and replaced housing bcs it was in very bad condition. Everything was fine. Max battery capacity was like 87%. I fixed it, tested it and everything was working perfectly. After like 2 days i turned on the iPhone and for me i knew something went wrong at this time. The battery stopped charging already. 3uTools showed me “no data” on battery and every 3 minutes just started rebooting it self. If i go to settings, battery and battery health i only see here is unlimited loading. So i just buyed a new battery and test it out and nope. Still the same problems. I cant find any fix to this problem so i asking u guys for a help. Thx a lot.

If you have replaced the battery the next thing to check is the resistor on the battery data line. It commonly gets knocked off or nudged as it is near the battery connector. It will need to be micro soldered back on. That’s why the error report mentions unhealthy and will restart every few minutes.
