16:45 <ncopa> is there anything that can be done to improve the battery time? I have worked ~3 hours now and have 35% battery left. mpb 14, Linux ncopa-mbp14 6.2.0-rc3-7-asahi #1-Alpine SMP PREEMPT Wed, 25 Jan 2023 13:07:25 +0000 aarch64 Linux

16:45 <ncopa> or is that normal?

16:57 <ncopa> i have done 5-6 git clones over non-optimal wifi and rebuild kernel 5-6 times, and thats it basically

16:58 <ncopa> its down to 25% battery now

17:04 <tobhe_> my m2 air lasts a lot longer. do you have the graphics driver/dcp enabled? If not, that is something you could try

17:08 <ncopa> 12% now

17:11 <ncopa> how do i check if i have dcp enabled?

17:11 <j`ey> it's in your kernel config

17:12 <j`ey> there's probably a way to check in sysfs or so, dunno off the top of my head

17:12 <j`ey> (or in dmesg I guess)

17:12 <ncopa> [ 7632.536934] apple-dcp 38bc00000.dcp: Woke up

17:12 <ncopa> i guess i have apple-dcp

17:12 <jannau> energy use on the m1 pro/max notebooks

17:13 <jannau> is considerably higher than on the m1 and m2

17:14 <ncopa> 8% now

17:14 <ncopa> i guess kernel compile drains it

17:15 <ncopa> i need to find a place with power

18:23 <mps> ncopa: try to set cpu freq governor to SCHEDUTIL

18:24 <mps> maybe it could help to some degree

18:24 <mps> though I didn't tested it much

18:26 <mps> maybe even conservative is better than ondemand

21:45 <ncopa> looks like the alpine linux-asahi kernel used ondemand cpu freq governor while asahi linux's pkgbuild uses shedutil

21:57 <mps> well, shedutil is not much better on battery saving, maybe to some degree but I never seen any significant difference

21:58 <mps> I started linux-asahi with performance but on request from the user switched to ondemand because performance makes air models too hot

21:58 <mps> now I'm experimenting with shedutil

21:59 <ncopa> same, i think we should switch to schedutil by default

22:00 <mps> I'm ok with this

22:00 <mps> anyway, most are enabled and could be set by users on boot, or later during work
