Testing charging threshold using command-line

Charging mode can be set by using echo command in terminal.

To enable Extend Battery Life Mode

Require root privileges

echo '80' | pkexec tee /sys/devices/platform/lg-laptop/battery_care_limit


To disable Extend Battery Life Mode

Require root privileges

echo '100' | pkexec tee /sys/devices/platform/lg-laptop/battery_care_limit


sudo also can be used in place of pkexec in the above commands as both sudo and pkexec can be use to run commands in root mode. To make use of polkit rules, the extension uses pkexec.

The current threshold value can also be read using cat command in terminal.

cat /sys/devices/platform/lg-laptop/battery_care_limit


Condition for applying threshold

  • Accepted values for battery_care_limit : 80 or 100

If charging threshold are applied successfully using above commands, the extension is compatible.
