charge-stop sets the battery charge threshold of a laptop: the percentage above which charging stops. Keeping the threshold below 100% extends battery lifespan for laptops that spend most of their time plugged in.
The daemon (charge-stopd) manages the sysfs attribute directly and persists the setting so it survives reboots and suspend; firmware on many laptops resets the threshold across these events. A companion CLI (charge-stop) talks to the daemon over a UNIX domain socket, speaking a small REST API:
GET /v1/threshold report the current threshold POST /v1/threshold set and persist the threshold POST /v1/restore re-apply the persisted threshold

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
On Arch Linux, snap can be installed from the Arch User Repository (AUR). The manual build process is the Arch-supported install method for AUR packages, and you’ll need the prerequisites installed before you can install any AUR package. You can then install snap with the following:
git clone https://aur.archlinux.org/snapd.git
cd snapd
makepkg -si
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
If AppArmor is enabled in your system, enable the service which loads AppArmor profiles for snaps:
sudo systemctl enable --now snapd.apparmor.service
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install Charge Stop, simply use the following command:
sudo snap install charge-stop
Browse and find snaps from the convenience of your desktop using the snap store snap.
