In Fedora 36: 6-8 hours of moderate use (web browsing or light gaming), and 4-5 ...

Are you running any sort of customizations? I'm at almost exactly half of that on my i5-1260p model with 32GB RAM (Ubuntu).

I've tried TLP and autocpufreq.. the latter maybe netted me an extra 30mins?

I might have to give Fedora a try for the first time in a decade..

I'm using TLP and also have the fedora power settings set to "battery saver" (although TLP might override that with its own optimizations?)

Yeah that toggle in newer distros is managed by power-profiles-daemon which ships with modern versions of Gnome. From what I've read you're better off only running one of these power management apps as they can conflict with eachother.

Sounds like you're getting totally fine battery life though so I wouldn't stress about it!

I'm about to give Fedora a whirl. Hoping I can get close to your numbers.

I'd recommend making sure you have thermald (2.3+, current version is 2.5) installed. It's the best way to load/use the proper adaptive DPTF tables from the BIOS.

Also, it's important to make sure you're running the latest kernel. Basically every release since 5.15 (up to 5.19 now) has had pretty important perf/power fixes for Alder Lake.

On debian 11 you need 5.19 kernel from experimental repo to get the C10 state.

And thanks for your help on https://community.frame.work/t/12th-gen-battery-questions-on...

Yeah that's probably it. I'm only on a 5.15.x kernel.

I'm running Secure Boot w/ LUKS so installing a mainline kernel is a real PITA.

I'm getting similar with out of the box Fedora, just following the install guide on their site.
