4 weeks ago If you laptop X30 notebook has the feature to change charging threshold, then most likely you can linux kernel will support it and so will this extension. The charging threshold is not a software feature but is a hardware feature that manufcaturer provide on a BIOS level, so the charging threshold are applied even when the laptop is powered OFF. So here are some question.
- Does you laptop, have the feature to turn on/off "Battery life extender" in Windows or in BIOS. Are you able to use this feature? If no, then most likely you wont find support in Linux as well
- If yes, than most likely samsungs WMI for linux kernel will detect it (unless the way to read Embeeded controller is different) If linux kernel has detected your model is compatible, these path will be exposed in sysfs. you can check by using ls command in terminal
ls /sys/devices/platform/samsung/You should see battery_life_extender sysfs path in this output.
If the path is present you can enable charging threshold by writing 1 to it or disable charging threshold by writing 0
echo '1' | sudo tee /sys/devices/platform/samsung/battery_life_extender
If this works, then the extension is compatible with your model.
Post your output for ls /sys/devices/platform/samsung/ and you kernel version and your linux distribution your are using (ex Fedora 39, Ubuntu 22.04)

Extension isn't compatible with my Samsung X30 (2020):
Nonetheless, I do have /sys/class/power_supply/BAT1/capacity currently set to 85 (legacy from previous Windows installation). Also sys/class/power_supply/BAT1/uevent with all settings:
I can't change it back to 100 to test it but it seems to be a way.
