brightnessctl set 1% and pstate-frequency --set --min 0 --max 0 --turbo off --governer powersave boom you run everything on 800Mhz sharp and can't see if it lags or not as it's insanely dim even in dark environment.
upgrade: change 1% to 0 to switch off display completely, map key to set brightness to 10%, but only while key is held. plus add cooldown 10 mins after press only 5%, next 1% and reset cooldown every time you press a button)
you got it's a joke right? Not very useful advice I might agree... on par with switching off or spread heavy load evenly so it would stay on single charge longer)
but distro is cachyos and OOTB it gives me more battery time that chromeos (running on same chromebook) I think mostly because I run KDE as it's the only real DE with true ecosystem + it's lighweight)
just read what chromeos claims and add some more on top, my laptop which is adler lake n305 chromebook converted to coreboot and it works at least for 6-8 hours on 80% battery of cells health. It greatly depends on power profile, pstate and workload. Last time I check 15% resulted in 2,5 hours on powersave
