Charging & USB Control Chip for Oppo R15 Pro

The Charging & USB Control Chip in your Oppo R15 Pro manages all incoming charging current — negotiating the correct voltage and current with the charger adapter, controlling fast charging protocols, and managing USB data communication when the phone is connected to a computer. When it fails, your Oppo R15 Pro may refuse to charge, charge very slowly, or not be detected by a PC even with a working cable.

Test with multiple confirmed-working cables and adapters first. If the charging port connector is physically intact and undamaged but the phone still will not charge or be recognised by a computer, the Charging & USB Control Chip on the Oppo R15 Pro motherboard is the likely cause. A board-level technician can confirm with diagnostic tools.

Yes. The Charging & USB Control Chip manages fast charging protocol negotiation between your Oppo R15 Pro and the charger. If the chip is partially failed, you may find that normal slow charging still works but fast charging has completely stopped — a specific symptom pointing directly to this chip.

No. This is a micro-SMD chip soldered onto the Oppo R15 Pro motherboard. Replacement requires hot air rework equipment, flux, and professional board-level repair skills. Incorrect replacement risks shorting the charging circuit and causing further damage to the motherboard.

Yes — a 7-day replacement warranty against manufacturing defects is included. An unboxing video is mandatory for all warranty claims. Once the chip has been soldered it is considered used and cannot be returned. For more information, check out SAHII's Return Policy.
