Battery Life concern

[Luka_Jioshvili]

I recently found frame work laptop from Linus tech Tips channel , i really liked everything about this laptop ,but my only concern is that the battery lifetime.
I couldn’t find the number of hours previously correctly . I saw that battery life varies from 4 hours to 10. I wonder how many hours will I have approximately while coding ( web programming React/Vue.js )using web browser , editor(visual studio code / webstorm ) , with normal ( medium brightness level ) on windows 10 balanced power settings no tweaks whatsoever .
Build of ( processor of i5 1135g7 , 1x 16 GB Ram, WD 500GB SN750 ) .

Probably will get 4 - 5 hours. I would get 6 doing basic word processing

In a well tuned EndeavourOS (arch) Linux and I’m getting consistently 10-11 hours in mixed web browsing, 3d printer slicing, etc workloads. 8-9 in local video playback. Both with medium ~100-200 nits brightness…

Extending endurance away from plugs using external battery packs also works quite well, depending on the size and output power of your packs.

That is really amazing. Did you follow the steps in the guides posted in the forums or did you tune it yourself? I’m getting around 6-8 hours on my EndeavourOS setup with Medium-Low nits brightness.

Do you mind if I ask you to share your settings / tweaks? It would be interesting, not only fo Arch (and derived) users, but for any Linux users in general. Thanks!

Factors that helped me get down to 102000 current_now in super low power idle testing are mostly here:

[TRACKING] Linux battery life tuning

Heres the list of factors that made a difference in getting to ~2.2W idle draw, in roughly the order of effectiveness from high to low… Brightness manually set to 1 (this is the single biggest factor I have found) Airplane mode (ax210 is pretty power hungry even when doing nothing) TLP bat mode sets all the rest of the important power saving and tunables automatically PSR turned on allowing for C10 idle state (no issues with this observed in kernel 5.15.x for me). Arch Linux + Plasma + Waylan…

and here:

Battery Life?

All of a sudden it started working for me as well. Computers… where the definition of insanity does not apply. Looks like the lowest value that /sys/class/powercap/intel-rapl:0/constraint_0_power_limit_uw will accept without going down to 0 is 125000. Noticeable but tiny input lag at that low of a PL, but it does result in a functional system. Honestly its not much worse than my 6Y30 processor tablet pc had when it was allowed to go full speed lol. Looks like 11-12 hours of battery endurance av…

A few updates though, I’m now using plasma+X11 instead of Wayland as my daily driver DE, as Wayland seems to have some ugly regressions and higher idle use lately. I think I might also have missed documenting one TLP parameter that also helped, setting pcie_aspm to superpowersave via tlp-gui…

Yeah, I’m doing the same: Wayland it’s a great idea, but not mature enough to be used as a daily driver (unless you are trying to contribute to it finding things that need to be fixed / improved). I’m more a Gnome guy, but I’m trying to use i3 (on X11) as daily driver with the final goal of being much more familiar with the concept of using a GUI almost entirely with the keyboard; I already am very familiar with Vim (my editor of choice, even for coding), why shouldn’t I succeed with i3 too?

Thanks for sharing!
