Hey everyone I hope you have a good day, I recieved an iPhone 6s+ came in with no power. I diagnozed it and I found an OL on U2300 area also known as Tigris IC. I changed the chip and the amps drawn only at 0.42amps. From experience I tested it with a good new Tristar IC and I still get the same result.
Where should I test next? For instance what is the power sequence of this particular model. Thanks!
