Overview
What this part is
The charging port on the Xiaomi Redmi 7A is mounted on a small board at the bottom of the phone, linked to the main board by a flex cable. Daily plugging in, pocket fluff and moisture wear the port, which causes loose, slow or intermittent charging.
Before replacing it, check the cable and charger, and gently clear any lint from the port with a wooden toothpick. If charging is still unreliable, a new board is the usual fix.

- Power the phone off and remove the SIM tray.
- Warm the edges of the back cover and lift it off carefully with a thin pick.
- Remove the screws and the lower cover, then disconnect the battery.
- Disconnect the board flex and any antenna cables, then lift the old board out.

FAQ
Frequently asked questions
Will this fit my Redmi 7A?
Yes, if Settings › About phone shows Redmi 7A. It does not fit the Redmi 7 or Redmi 8A. Compare your old board with the photos before fitting.
Does it fit the Redmi 7?
No. The Redmi 7 has a different charging board. This one is for the Redmi 7A only.
Will it fix a phone that will not charge at all?
Only if the charging port is the cause. Try a known good cable and charger first. If the phone still does not charge with a new board, the battery or main board may be faulty.
Is it made by Xiaomi?
No. It is a brand new, OEM-quality charging port board made to fit the Xiaomi Redmi 7A, and it is tested before dispatch.
Should I fit it myself?
We recommend professional installation. The Redmi 7A back cover has to be heated and lifted, and the battery must be disconnected before the board is removed.
