Laptop battery charging limit

[Tomek]

KDE has section in System Settings for this. I have no idea about other DE.

How to set battery charging limit in kde?

In the KDE system settings → Power Management → Advanced Power Settings [image]

In terminal you can do this:

echo 20 > /sys/class/power_supply/BAT0/charge_start_threshold
echo 90 > /sys/class/power_supply/BAT0/charge_stop_threshold

First command enable charging at 20% battery level, second disable charging at 90% battery level.
