TLP VS cpupower-gui

Usually full charge give me about ~5 hours, after install tlp here https://linrunner.de/tlp

https://github.com/linrunner/TLP/

They definately do conflict, it was discussed back when ppd first arrived: https://github.com/linrunner/TLP/issues/564

If you're certain your GPU has deeper power saving states than P8, I would start by checking why it's not using them. Maybe tlp, powertop or nvtop (or their documentation) can help.

I use TLP for my personal laptop https://linrunner.de/tlp/

if you don't already have it installed, you could try tlp: https://linrunner.de/tlp/

Install TLP

Maybe will be helpfull https://github.com/linrunner/TLP/issues/596

I use cpupower-gui for this, and installing the .deb on their releases page works flawlessly. In my experience, it does a pretty good job at improving battery life, even on modern systems.

I was looking into using envycontrol to disable the dGPU in linux, and maybe ryzen controller or cpu-power to limit cpu power usage.

For power management, you could use something like cpupower-gui to underclock the CPU whenever you need to conserve battery.

There's https://github.com/vagnum08/cpupower-gui but its GTK based

I use gnome so I have no clue what the KDE slider does, sorry! But you should check out cpupower-gui

You can also use cpupower-gui to park cores, although Phawx mentioned he used some other tool. In this tool, you just need to uncheck the cpu you need to turn off.

Also I would recommend using cpupower-gui if your frequencies are too high. This tool lets you do frequency scaling and lets you select a governor in a gui.
