Charging PCB Complete Flex for Infinix Hot 4 Pro

The Charging PCB Complete Flex for your Infinix Hot 4 Pro is a complete replacement of the charging board assembly — used when the USB port has been physically damaged, the charging IC on the board has failed, or charging and data transfer functions have degraded beyond what a port cleaning or cable replacement can resolve. It includes the full PCB board with the USB port, flex cable, and onboard microphone ready for direct installation on your Infinix Hot 4 Pro.

Yes — this OEM-grade replacement is manufactured to the same voltage rating, connector specification, and board layout as the original charging PCB on your Infinix Hot 4 Pro. Fast charging support, USB data transfer speed, and microphone functionality will all be restored to factory standard after professional installation.

Not necessarily — intermittent charging caused by positional sensitivity is often due to a worn or damaged USB port rather than a full board failure, and can sometimes be resolved with a port-only replacement if the rest of the PCB is intact. However, if the port pins are visibly bent, the board is cracked, or the issue persists after a port-level check, the Charging PCB Complete Flex is the correct and complete solution for your Infinix Hot 4 Pro.

It is a moderate to involved repair requiring the phone to be opened, the battery disconnected, the old PCB flex carefully detached from the motherboard and any anchoring brackets, and the new assembly correctly routed and connected. On some Infinix Hot 4 Pro devices the charging PCB is shared with the microphone or antenna lines — professional installation is recommended to avoid disturbing adjacent components.

Yes — a 7-day replacement warranty covering manufacturing defects is included. An unboxing video is mandatory for all warranty claims. Charging PCB modules with physical damage or that have been installed are not eligible for return. For more information, check out SAHII's Return Policy.
