change cpu-freq on manjaro 20.04 xfce

[thumbsup]

You can see current system current (while on battery):

Code:

cat /sys/class/power_supply/cw2015-battery/current_now

Play around with some settings, but I'm on a 5.7 kernel, and it seems that on a modern kernel, the scheduler does a really good job of handling the cores to keep power use minimized.  You could try turning off most of the cores to save a bit of power, but I'm not sure that gains you a lot.

But you've got USB-C charging.  IMO, the far easier option is to just carry a USB-C battery bank (build a DIY one if you want and source the 18650s locally).  I don't think even a lot of tweaking will change stuff as much as just carrying more battery.

The output for this is always "0"......
I have two powerbanks and two foldable solarpanels with me. Still running out of power is a big worry for me :-)

you probably want:
sudo cpupower -c all frequency-set -g conservative

read cpupower manpage for all the details.

That does the trick - "powersave" works  as well.



Maybe I'm wrong but the first default system seemed to be more stable and less power-consuming to me. With Manjaro I have the feeling the laptop is producing way more heat now.
