@outsidefactor . Here is what I have done. I have a Asus laptop and the approach which I have adopted is given below. Hope it helps you as well.
Create a service file named battery_charge_threshold.service like this.
[Unit]
Description=Set the battery charge threshold
After=multi-user.target
[Service]
Type=oneshot
ExecStart=/bin/bash -c 'echo 80 > /sys/class/power_supply/BAT0/charge_control_end_threshold'
[Install]
WantedBy=multi-user.target
Move the file to this location /etc/systemd/system
Run the following commands.
sudo chmod 644 /etc/systemd/system/battery-charge-threshold.service
sudo systemctl daemon-reload
sudo systemctl enable battery-charge-threshold.service
After doing this, charge threshold of 80% (as per service file) will persist between reboots. It will also stop charging the battery if the current level is above 80%. Hope this helps. I have been using it for almost 1.5 years without any issue.
Thankyou for posting your workaround!
I will hold off putting it into action for a bit so I can continue to work with @anon89812132 on getting the GUI working, but thanks for letting me know your (quite elegant, if I may say) fix.
