Every 3 minutes my iPhone SE restarts

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.

@imicrosoldering hey i got news. The resistor is missing there and i dont know how to get one. If i look under the mikroscope, i see only one transistor on the left. Photo what i means is here: https://ibb.co/x18XfkL

@lolxd3097 The only component you need is the one in the square. If it is missing just jumper the two pads as it is only a data line.

Is there any risk jumping 2 pads with conductive glue instead of resister?

I accidentally nudged the resisters too. Now i jumps pad with conductive glue and phone is working but i feel it is hotter while using.

For anyone working on the first gen se or the iPhone 5 there is a right way to disconnect the battery connector and a wrong way.

The wrong way is to disconnect it like a usual connector, this leads to components being knocked off the board next to it as mentioned in the comments.

The right way is to use a spudger or a pair of tweezers and slide it between the battery and motherboard and lift the connector up. That way there is no way you can damage or knock off components.
