iPhone 6s Not Charging - GSM-Forum

Hi i have had an iphone 6s brought in yesterday. Customer says the phone will show charging but the battery % wont increase meaning fake charging. I tried replacing the charging port first still the same, replaced the battery still nothing. Replaced Tristar, Tigirs, put a jumper on Q4500 pin 2-3. There is no short on PP_VCC_Main, or PP_BATT_VCC. Very confused.

Found the problem! while replacing the TRISTAR I probed around the pins and found the TRISTAR_BYPASS shorted to the ground. There is only one cap on that line and that was the culprit.
