Overview
What this part is
On the Xiaomi 12 Lite, the USB-C port is mounted on a small board at the bottom of the phone. The board connects to the main board through a flex cable. Daily plugging in, pocket lint and moisture wear out the port, so the cable feels loose or charging stops.
Before replacing it, try a different cable and charger, and clean the port gently with a wooden toothpick. If the phone still charges slowly, only when the cable is held at an angle, or not at all, the port board is the likely fault. The board may also carry the bottom microphone; compare your old board with the photos.

Professional installation
How a technician fits this part
- Power the phone off and remove the SIM tray.
- Warm the back glass to soften the adhesive and lift it off carefully.
- Remove the screws and lower cover, then disconnect the battery.
- Disconnect the main flex and antenna cables, then lift out the old port board.
- Fit the new board, reconnect every cable and test charging before closing.
- Refit the lower cover, screws and back glass 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 12 Lite?
Yes, if Settings › About phone shows 12 Lite (model 2203129G). It does not fit the Xiaomi 12, 12X, 12T or any other model.
Does it fit the Xiaomi 12 or 12T Pro?
No. Those phones use different charging boards. This one is for the Xiaomi 12 Lite only.
Will it bring back fast charging?
If the old port was the fault, yes. Fast charging also depends on a working battery, the charging chip on the main board, and the correct Xiaomi-compatible charger and cable.
Is it made by Xiaomi?
No. It is a brand new, OEM-quality charging port board made to fit the Xiaomi 12 Lite, and it is tested before dispatch.
Should I fit it myself?
We recommend professional installation. The 12 Lite must be opened with heat, the battery disconnected, and small coaxial antenna cables refitted correctly.
