Phone shuts off after a few minutes

Hello.


I recently replaced the glass back side of the iPhone 11. We don’t replace the glass it self we buy the frame with the glas already placed and just move the components. Been doing that since the iPhone 8 and never had an issue. I felt this repair went pretty well but when i started the phone and tried to test it, it just turns off. Right after it turns of it starts again with the apple logo. The it turns off again and repeat. I have tried everything i can think off but this still happens. There is no visible damage to the motherboard. I checked with a microscope. I have no clue how this has happened or how it fix it. Here is a list of things i have tried. ESD armwrist band and ESD safe table was used all the time.

  • I took out the motherboard and connected charging port, batteri and screen to it. I started the phone by plugging the power in. This to make sure no other components or the new case is connected. I also tried this without the charging port and with the power on button instead.
  • I tried disconnecting one by one component and replacing the battery.
  • I tried using 3Utools and the phone in DFU mode to reset it.
  • I put the motherboard in a reflow oven at 180 degrees celcius for about 1 hour.

So yeah, basicly tried a lot of things with no luck. Any ideas?

Is it consuming power through dc before prompt to boot ?.

@tech_ni It's consuming 0.35A before boot and when the apple logo shows up it show 1.64A.

Current seems very high for just apple logo, have you checked nand power rails.

Settings -> Privacy -> Analytics & Improvements -> Analytics Data -> Search for “thermalmonitord”

If there’s a log there that says “thermalmonitord returned not alive” then try replacing the charging port
