Xiaomi Redmi 8: Redmi Note 8: Charging port failure recurred after repair

Wed, 04 Mar 2026 12:45:37 -0700

Hi everyone,

I’m having a persistent charging issue with my Redmi Note 8 and would appreciate some technical advice.

The Problem: My phone has stopped charging completely. When I plug in the cable, there is no vibration, no charging icon, and the LED indicator doesn't light up.

Background:

This exact issue happened about 1 day ago.
At that time, I had the charging port board (sub-board) replaced at a local shop, and it worked fine until now.
Recently, the charging became "ficky" (intermittent) – I had to wiggle the cable to get it to charge – before it died completely today.

What I’ve tried so far:

Cleaned the USB-C port with compressed air and a toothpick (no lint found).
Tried multiple official Xiaomi cables and power bricks (all work fine with other devices).
Inspected the port for physical damage; the pins look okay to the naked eye.

My Questions:

Is it common for the charging sub-board on the Redmi Note 8 to fail repeatedly?
Could this be a loose flex cable connection between the sub-board and the mainboard instead of a broken port?
Should I try replacing just the charging board again, or could it be a deeper charging IC issue on the motherboard?

Thanks in advance for your help!
