Laptop/ASUS

In order to automatically change the value at boot, create the following systemd service:

/etc/systemd/system/battery-charge-threshold.service

[Unit]
Description=Set the battery charge threshold
After=multi-user.target
StartLimitBurst=0

[Service]
Type=oneshot
Restart=on-failure
ExecStart=/bin/bash -c 'echo '''60''' > /sys/class/power_supply/BAT0/charge_control_end_threshold'

[Install]
WantedBy=multi-user.target

and then enable it.

Restart=on-failure and StartLimitBurst=0 are used to work around the service failing with a error.

This error is due to the service being started before asus-wmi could be loaded by the kernel (noted as in the journal), making it impossible to write there.

The combination of those two options allows unlimited restart of the service for (set to 10 seconds by default in ), leaving enough time for the sysfs path to become available and writable and thus ensuring the fastest execution of the service.

The battery's charge_control_end_threshold power supply class attribute does not initially exist. It is added to the sysfs(5) directory by the asus-nb-wmi kernel module. Create a udev rule for asus-nb-wmi to set the battery's charge threshold:

While this setting will persist after suspending to RAM, it will be reset when resuming from hibernation. In order to re-execute the service after hibernation, use one of the methods described in Power management#Sleep hooks.

E.g. if using Power management#Generic service template, enable an instance of the created template using:

# systemctl enable sleep@battery-charge-threshold.service

If creating a script as described in Power management#Hooks in /usr/lib/systemd/system-sleep, use something similar to:

Do not forget to make the script executable.

Another (more simple) way to force the charging threshold is by using , which provides a service and an intuitive terminal interface to change the threshold by typing .

Note however, that the AUR packages is orphaned at the current state.
