Overview
What this part is
On the Xiaomi Mi 9, the charging socket sits on a small board at the bottom of the phone, together with the microphone connection. Daily plugging in, fluff and moisture wear the socket, so charging can cut in and out when the cable moves.
Replacing the board gives you a fresh socket. Try a different cable and plug, and clean the port gently first, as a bad cable is a common cause. If the phone still does not charge with a new board, the battery or main board may need checking.

How to check your model
Open Settings › About phone. The device name should read Mi 9. The model number is also shown there. Compare your old part with the photos before fitting.
The Mi 9 has three rear cameras. The Mi 9 SE also has three, but it is a smaller phone, so check the name carefully.
Professional installation
How a technician fits this part
- Power the phone off and remove the SIM tray.
- Warm the Mi 9 glass back to soften the adhesive and lift it off slowly with a thin pick.
- Remove the screws and inner panel covering the bottom of the phone.
- Disconnect the battery before touching any other connector.
- Unplug the board's flex cable, lift out the old board and fit the new one in the same place.
- Reconnect the battery, test charging, data and the microphone, then close the phone and seal the back with new adhesive.
Check that the part matches the device before fitting it or removing any adhesive backing. Once a part has been fitted, it cannot be returned for a change of mind. Faulty parts are always covered.
FAQ
Frequently asked questions
Will this fit my Mi 9?
Yes, if Settings › About phone shows Mi 9. Compare your old board with the photos before fitting. It does not fit the Mi 9 Lite, Mi 9T or any other model.
Does it fit the Mi 9 SE?
The Mi 9 SE is a smaller phone, and its charging board looks very similar. Check the device name in Settings › About phone and compare your old board with the photos before fitting.
Should I try cleaning the port first?
Yes. Fluff in the socket often stops the plug going fully in. Clean it gently with a wooden or plastic pick, never metal, and try another cable. If charging is still faulty, the board needs replacing.
Is it made by Xiaomi?
No. It is a brand new, OEM-quality charging port board made to fit the Xiaomi Mi 9, and it is tested before dispatch.
Should I fit it myself?
We recommend professional installation. The glass back is glued on and needs heat to remove, and the battery must be disconnected first.
