Key Features & Components
- Integrated IC Chip: Higher-quality OEM versions feature a built-in power management IC chip. This protects your device from short circuits and supports factory-standard fast charging.
- Multi-functional Board: Along with the USB Type-C charging dock, this sub-board contains your phone’s main microphone and the headphone audio jack.
- Common Failure Signs: You likely need to replace this if your device only charges at specific angles, fails to connect to a computer, loses fast-charging capabilities, or your voice sounds muffled during calls.
