disable vodoogpio.ket, the processor will be set to idle at a minimum of 3 to 5 w .
Even so, the minimum power consumption is set at 50w, in windows 10 it is set at 15w (with energy meter).
I suspect that Nvidia is not disabled, I cannot think of another reason why the minimum consumption could be so high, which explains the short duration of the battery.
hi Laui, did I test xiaoMGitHub efi 3.0.3? I have a panic in the kernel.
