To disable Smart Charging Mode

Require root privileges

echo '0' | pkexec tee /sys/devices/platform/samsung/battery_life_extender


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/samsung/battery_life_extender
