Chosen Solution
Hi I’m phone technician but I have difficulties to solve problem of i6s than not charging when powered on. I changed tristar, tigris, charging port but nothing solved my problem.
Check tigris_battery_swi. Diode the dock connector. Maybe replace or bridge Q2300. When I have run into this problem I replace the battery and dock connector, remove Tigris and tristar and diode. But the problem is usually the SWI line.
