Hi.I have an iPhone 6s.No water damaged.There's a clean motherboard.

3.7 volts is coming to the battery connector.But not turning on.I checked the motherboard.I found that PP_GPU line is shorted.I injected 1.0V,2A on C2012.I didn't see any change other capacitor on the line.
How can I find the short ??? Thanks.

You'll need to check some power lines in diode mode.  Do you know how to do that?

Does itunes recognize the phone?  What kind of amp draw are you getting from the ammeter?  Amps from DC power supply?
