Battery charging level threshold

[jkc-2]

Hi all,

Modern laptops provide a way to limit battery charging level. This is a good way to preserve battery health over time when using the laptop docked for frequently. Would other people be interested in having it integrated to Omarchy setup ?

Coming from Gnome I have little knowledge on Hyprland but this seems like a possible first implementation :

For reference :

Specific to Asus https://aur.archlinux.org/packages/bat-asus-battery-bin

And the Gnome details https://vdwaa.nl/gnome-upower-charge-thresholds.html

Oh yes, I second this!

Another option would be to have a choice on install to choose between power-profile-daemon and TLP.
TLP comes with battery threshold

I’d like to see that implemented too. For most devices is as simple as write to the threshold files at /sys/. Linux Kernel already exposes it, a shell script should do the work.

One of the first things I wanted to configure booting up Omarchy. In the interest of the philosophy of avoiding file changes to ~/.local/share/omarchy, I wrote a crate to solve this issue from the cli without having to install tlp and keeping power-profiles-daemon. Hope this helps

This might only work on thinkpads but go ahead and try

sudo pacman -S --needed --noconfirm tlp

Then edit this file

sudo nano /etc/tlp.conf

Find the lines regarding battery settings, remove the leading # to uncomment:

START_CHARGE_THRESH_BAT0=75
STOP_CHARGE_THRESH_BAT0=80

Done

I think this would be a great default to have in Omarchy. We could have a nice menu (or even maybe a TUI) to manage that config.

[nicoestrada]

I wrote a tool myself for this exact reason, would love for it to be preinstalled with Omarchy or at least the ability to take care of this out of the box. And it has a TUI too. I've seen some people have to disable power profiles daemon just to install TLP. Not sure if Omarchy devs understand yet this is a side effect of not having this ability

Of course depends on if your machine exposes the path to the battery too, you can write the path yourself and save

[gabrielvincent]

Can you share the tool you created? I'd love to give it a try.

[nicoestrada]

Sure no problem it's here

Open to feedback and contributors too. Ideally if we can build out the TUI to show more insights to the battery I think it can be improved upon there

[gabrielvincent]

That's cool! I was thinking about developing something similar. Maybe we can join efforts? I'm going to work on a PR to include start_threshold. Do you have an idea of what you want to implement in this tool?

[nicoestrada]

Absolutely! Make the PR when you're ready and I'll merge. Important battery health and insights from a TUI would be great. Keep in mind that some laptop machines dont expose this path too. I think Acer? Persistence is also important. That way when machine restarts or powers off, the threshold is still working. But I think for now improving the TUI with more insights is a good direction
