MateBook X Pro Slow Charging: Reason & Fix


Forget CPU and GPU thermal throttling — charge rate throttling is now a thing.

Exposed charging circuit with shielding cover peeled off. Plugged in, CPU idle.

  • The charging circuit doesn’t have enough cooling and tends to overheat.
  • Since the charging circuit and the CPU use the same heatsink, the heatsink already warmed by the CPU does not have a low enough temperature to efficiently cool the charging circuit.
  • The charging rate is temperature-dependent, but the charging circuit doesn’t seem to have a temperature sensor, so Huawei might have gone super conservative about protecting the charging circuit and modeled its temperature after the CPU temperature.
  • Therefore, even when the CPU is a little bit warm, the charging rate thermal-throttles.


  1. Add 1mm-thick thermal pad to the circled area of the motherboard’s backside.
  2. Replace the existing thermal pads on the charging circuit components with better pads, 2mm and 0.5mm.

I am on 1.18 Bios and i constantly have this issue. Even when CPU is idle at 48-55 c charging gets stuck for hours and hours until i close the lid. It then charges, i think, normally…


i have matebook pro x 2021 laptop iam facing the slow charging issue taking morethen 3 hours to make full charging
