charge_threshold

Set a charge threshold for asus laptop in ubuntu This only works if your computer hardware support it, go to MyASUS app to check this feature

check the battery name

the following command will return your battery name, mine is BAT0 ls /sys/class/power_supply

create a systemd service to set the battery charge stop threshold on boot

Before creating the systemd service, check if your laptop actually has charge_control_end_threshold in /sys/class/power_supply/BAT* (without it, this won't work): ls /sys/class/power_supply/BAT*/charge_control_end_threshold continue if it returns the path to charge_control_end_threshold now create a file called battery-charge-threshold.service in /etc/systemd/system by the following command sudo editor /etc/systemd/system/battery-charge-threshold.service in the file, paste the following script

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

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

[Install] WantedBy=multi-user.target

Here, change BATTERY_NAME with the name of the battery (mine is BAT0), and CHARGE_STOP_THRESHOLD with the battery charge stop threshold you want

Remember that some systems' battery can only be set to some specific value as 60, 80, 100

Enable and start the battery-charge-threshold systemd service

sudo systemctl enable battery-charge-threshold.service sudo systemctl start battery-charge-threshold.service

If you want to change the battery charge stop threshold level

edit the /etc/systemd/system/battery-charge-threshold.service file, change the number restart the systemd service using the following commands:

sudo systemctl daemon-reload sudo systemctl restart battery-charge-threshold.service

Verify that the battery charge stop threshold is working

cat /sys/class/power_supply/BATTERY_NAME/status
