I just got an iPhone 5S with a broken screen and home button/front camera missing. I tried turning it on but there’s no reaction at all (no sound etc.). I tried removing and reinstalling the battery but it’s not working. The battery only had a voltage of about 2.5v, so I ordered a new one but it’s still not working. Is the logic board broken or am I doing something wrong?
If the new battery didn’t turn on the phone, yes there is something wrong with the logic board. If you have a usb voltage to see the incoming voltage is charging the phone then it’s a simple fix could be a defective charging port assembly. or it could be a defect logic board if the charging port assembly is replaced.
