iPhone 6 Charging Problem After Water damage
Hi @refectio !
Recently i repaired totally dead water damage iPhone 6. Phone boot and work fine. After 2 weeks start problems with charging.
First, phone wont charge, when i connected wallcharger, but via computer charge without problems. Now phone definitely stop charge. So i do:
Replace U1700 Tristar
Replace U1401 Tigris
Do hard jumper Q1701
Check all Tristar and Tigris caps for short - all is ok
Replace Dock connector
After measurement voltages i found FIRST problem, when i have connected battery and dock charging port to the motherboard Tigris E1 pin with name CHG_ACT_DIO is low - 0V. When i connect this line to 5V, phone still won´t work.
After measurement working board this line have 5V.
After cleaning board with ultrasonic cleaner phone start charge for only 3-5mins. After then, phone stop charging and do not want charge anymore. ,I must put board again to the ultrasonic cleaner and clean, board start charge for 3-5mins and after this time stop charging. To this problem is board fully working (i can power on board)
Tigris and Tristar i replaced 2-3x i used new one and one from working boar also. Same result.
Did you seen it before?
PS: I clean with ultrasonic cleaner only area below SIM card connector, i do not clean the entire bord. I do not believe that there is short.
Thanks for your question
Best regards, Tomáš
