Feature request: Samsung battery limiting

[wakeup]

Hello,

Samsung on Windows has a tool which prevents charging over 80% to extend its life. Is there any possibility that this could be implemented under Linux too?

Thank you

2nd that request. With a non removable battery this is a key feature that is missing.

Any way to enable this would be awesome

When running Linux on the Samsung you can still use the 80% battery feature.
You need to go into the BIOS and set it there.

On laptops supporting this feature, you can do it with the following (as root):

Code: Select all

# enable battery life extender
echo 1 > /sys/devices/platform/samsung/battery_life_extender

# disable battery life extender
echo 0 > /sys/devices/platform/samsung/battery_life_extender

If you don't have this file, it means your laptop does not support this feature.
