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.

If the % shows then clearly the charging port isnt failing here, this is a logic board issue.

If it's false charging therefore there is likely communication problem between Tigris and your battery.

Check AND replace R2400 and C2400 (TIGRIS_BATTERY_SWI_CONN)
Check voltage PP3V0_TRISTAR
Check voltage PP3V3_USB
Check voltage PP5V0_USB
