Terrible Battery Life, PowerTop says Network Interface is consuming 12+ W

I’m on a Dell XPS 15 9570 running Manjaro KDE. I’m getting terrible battery life for some reason. I’ve installed optimus-manager but I’m still getting terrible battery life (2-3 hours) even on Intel mode. PowerTop often says that my network interface is consuming 12+ watts, and I’m not sure how to fix this.

HI @mod3sty :wave:

You can configure power saving methods wit tlp: https://wiki.archlinux.org/index.php/TLP

Instead of configuring /etc/tlp.conf by hand, you can also use tlpui

pamac install tlpui

(also specifically note tlp-rdw from there or @megavolt’s archwiki link)

For further assistance … please provide more information.

I’ve been using LMT so far, I’ll try to configure TLP and see what happens.

I installed TLP and removed LMT, and it seems that TLP is a lot better. My battery is great now! However, PowerTop is still reporting that my network interface is using 12.5W, despite the discharge rate being 4.09 W in total

The battery reports a discharge rate of 4.09 W
The energy consumed was 503 J
The estimated remaining time is 9 hours, 38 minutes

Summary: 1861.5 wakeups/second,  0.0 GPU ops/seconds, 0.0 VFS ops/sec and 33.4% CPU use

It’s just some wild guessing from powertop (hence “power est”(imated).
For some hardware it can be pretty accurate but in some cases it spits out total nonsense.

I see. I guess I’ll ignore those readings from now on. Thanks for replying!

yes, TLP is a good tool, you may also remove powertop

just launch sudo tlp-stat and it will suggest what else you can install end/or mask
