Chosen Solution
I am facing with this problem: Phone came with this problem: Not charge & battery drain. Replaced after confirm: Tristar. Result: Charging normally, no battery drain. Problem: No battery information / Random reboots. After replace TIGRIS: No result. In good one board 7/7+ BATT_SWI line is 1.6v, same as my fault board. Measuring diode mode SWI_AP_BI_TIGRIS = normal Measuring diode mode TIGRIS_TO_BATTERY_SWI = normal
