How to increase battery life in linux?

Question

linux

I have a surface pro 2, in the top ten the battery runs 6 hours of video, in Linux a maximum of 3 hours. Of all the distros, only deepin more or less showed autonomy, I thought it was the battery, I returned Windu for the test, the same 6 hours. Now I use manjaro i3, maybe there is some software in aur or somewhere else for normal power management? Or some tweaks? Why is there such a big difference in autonomy between Linux distros and Windows?

Answer 2

Well, what did you want? But it's free.
Poor ACPI support and very poor power savings.
Yes, Google cpufreq, this will allow you to lower the processor frequency and gain a little time, but still the same ERP is not supported by Linux. I don’t know if you have an HDD there, you can use sdparm to turn on the spindle stop after a while and unscrew AAM to a minimum.

Answer 3

I don't know about Manjaro, but Ububntu seems to have a power saving mode. But I would recommend reducing the processor speed and dimming the screen brightness. And I myself would close my eyes to this, and would remain on Linux)
