- 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.
