TLP VS TLPUI

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

Either use Vantage software on windows or take a look at this: https://github.com/d4nj1/TLPUI

You might want to give this a try: https://github.com/d4nj1/TLPUI

You might also be interesting in the GUI for customizing the energy profile: https://github.com/d4nj1/TLPUI

I had tried using tlp through tlpui, though I wasn't ever sure I was able to get it to work right, so I ignored it. I've gone back and disabled and saved it in that state for now.

You can also config tlp graphically with tlpui

There is a TLP UI which allows some graphical configuration, as far as i remember also exactly the strings OP wanted.

In any case, messing with /etc/tlp.conf by itself seems rather daunting. Maybe TLPUI is worth looking at?

Sidenote. TLP has no GUI. TLPUI however is a GUI for editing TLP config files, thus achieving the desired goal. It's available on AUR at least, probably other places as well.

I'd install the TLPUI app and do it from there. It has so many options.
