Battery life problem with laptop

I’m having a terrible battery life with Manjaro.
Even if I’ll use TLP(or CoreCtrl), set powersave everywhere, minimal brightness, even if I’ll disable all cores except 2 and reduce CPU TDP to 8W - barrely changes anything.
With 50% brightness and using browser on powersave it’s about 4h.
With WIndows it was 6-7h, so I’m kinda dissapointed.

I just want a battery life on par or better than with Windows, even at cost of performance. Maybe someone has an idea what to do?

Note: I’m using ryzenadj, so my TDP is increased, but it’s just an upper limit change, same bad battery life even if it isn’t used.

I havent used this but it makes Chris happy.Saving Power on a Linux Laptop - YouTube

there is also amd-pstate driver but i dont think that will work on your current kernel How to enable amd-pstate?

your mileage may vary.

This is normal, Linux has still got a long way to go on the power saving side/Battery Life.

Jump to 10:40 for Battery Life.

Tried this one, didn’t notice much difference.

I know that linux can be worse for battery life on some laptops. But I specified in my post that I’m willing to sacrifice performance(so it’ll be even lower than regular powersave) for the same/better battery life.
