iPhone 6 hangs at 200mA - GSM-Forum

7Axis · 11-11-2017, 04:29

Got an iPhone 6 that had a full VCC MAIN short and it's been removed, now drawing 0mA when off, once I power it on it starts to boot and gets stuck at 200mA and keeps drawing in that range forever, only the CPU gets slightly hot but I'd think it's normal,

What should I test to find the problem? thankkkkkkk you

If the phone hangs during the boot process, that means a critical sub-system is failing. Start by checking the voltage rails generated by the PMIC. Check for shorts and proper voltage. That may help you isolate which subsystem is failing rather than randomly swapping components...

Had the same problem.
Connecting USB power also wasn't switching 100% from DC power supply.
Replaced Tristar and now fixed.

No need to replace anything before confirm if working properly.

1. Plug usb and check BATT_VCC

Tristar is ok, you don't have to replace it.

What is your problem?
