Since there is no official program to manage the battery level from Asus and since TLP will not provide it because it doesn't follow the standard, I made my own!
An install script is provided, run it with sudo.
If for some reason the script doesn't find the interface file,
it's possible to override the interface search stage by
using the option --interface /<path>/<to>/<your>/charge_control_end_threshold.
If you have systemd, you can then start and enable the service.
It is highly recommended that you place the script in /usr/bin as it is used
in the rest of the project as script location.
From a root shell create folder /etc/asus-health-charging.d/.
# mkdir /etc/asus-health-charging.d
Find the interface and configure the program:
# echo $(find -L /sys/class/power_supply -maxdepth 2 -type f -name 'charge_control_end_threshold' 2> /dev/null) > /etc/asus-health-charging.d/interface
Install the script (assuming pwd is the local clone of this repository):
# cp ./asus-health-charging /usr/bin
If your OS uses systemd, install the unit file:
# cp ./asus-health-charging.service /etc/systemd/system
Start and enable the service:
# systemctl start asus-health-charging.service
# systemctl enable asus-health-charging.service
At last, install the man page:
# cp ./asus-health-charging /usr/share/man/man1
You can launch the script with (e.g. 60%):
$ sudo asus-health-charging 60
This command will set the battery level at which the system will stop charging. If the actual battery level is already beyond this threshold it will not be decreased.
With this one command the script will place the value inside charge_control_end_threshold
under /sys for immediate control and the file percentage in /etc/asus-health-charging.d
for restore on startup.
This command will test the nuber used, values must be between 15 and 100 (included).
The lower bound is because LiPo batteries suffer when discharged too much, and because I'm opinionated.
If you have systemd, the provided Unit file once enabled will restore the last session automatically, once enabled.
At startup it will run once and return. It is then possible to change threshold freely.
If you don't use systemd or want to use a different method to restore the charge limit you can use
$ sudo asus-health-charging --restore
Created to be used inside panel widgets and similar,
returns the value stored in charge_control_end_threshold.
