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 |
