    iPhone 11 Pro - No Power - PP1V8_Always

    Good morning. Id like to get someone elses input on what I am thinking could be going on with this phone. I have an iphone 11 Pro that does not boot, tried new batteries and all that. Connected to a PSU, it acts like the power button is not being pressed, when pressed does very little current (0.006ma). I checked diode readings on PP_VDD_MAIN which is ok (0.364), on PP_VDD_BOOST which was ok (0.387) and then PP1V8_ALWAYS which should be Open if im not mistaken but i get a diode reading of (0.510). I am guessing my problem lies here.. PP1V8_ALWAYS goes back to the PMU after passing through a capacitor. Would it be safe to assume the issue is on PMU? Really Im trying to see if others agree or if theres something I should try before going through all the work of a PMU replacement

    Well, I am not smart.. I moved on to another repair and put this one aside but thinking about it, if PP1V8_Always, always has voltage then it should not be an Open Line and I am mistaken lol. When I figure out what is going on I will update here for anyone who might ever find this useful one day.
