- Common Motherboard Fault Symptoms & Diagnosis:
* "No Charging" / Zero Amperage Draw (0.00A on USB Tester):
- When plugged into a charger, the device fails to negotiate charging or draws zero current, typically caused by blown input protection MOSFETs inside MT6375P.
* Fake Charging:
- The phone displays the charging lightning bolt icon on the display, but current remains trapped at ~0.10A - 0.20A and the battery level never increases or actually drains.
* Dead Phone / Auto Short on DC Power Supply:
- Internal breakdown of the high-side switching FET directly shorts the VBUS/VSYS line to ground, causing high current pull on the DC power supply immediately upon connection.
* Severe Localized Heating during Fast Charging:
- Handset triggers temperature warnings or stops charging after 2-3 minutes due to excessive thermal degradation within the MT6375P switching circuit.
