Hello, I have an iPhone XR which doesn’t turn on. It is not water damaged, and hasn’t been dropped. It shows no signs of life, and is not shorted. I tried hard resetting but nothing happened. When I plug it into the DC power supply and press the power button, it goes to 0.023 amps and doesn’t increase or decrease. Does anyone know what this issue may be? Thank you
From experience 0.023 amps would mean it is going straight into DFU mode. You could try and see if it is recognised with iTunes but most likely it will not. There could be a number of reasons this is happening. You can start by measuring the voltage on the NAND and CPU power rails. If these rails are there you will then need to check most of the reset lines. If all these are good it would point to a communication problem between the NAND and CPU. If it has suffered a drop it could have cracked one of the CPU coils, you might have to at least remove that shield so you can do a visual exam.
Hi! Another problem the phone could be having is that it just did a software update. My mom used to have an XR and those phones are known to have the BSoD after an update. Sadly that can’t be fixed. Other answers that are on this post could also be why ist not turning on. Hope this helps!
