Is there a Linux equivalent to Samsung Battery Life extender

[terry]

Looking into the samsung-tools, there is no such function to control the battery charge as in Windows so as to extend the battery life.

The Samsung battery life extender extend the batt life by limiting the full charge percentage to 80% so that the full charge/discharge cycle will be decreased to some extent.

I found the battery status and info under /proc/acpi/battery/BAT1, but I am not sure if it's possible to do the same by make changes to these files on the pseudo file system.

The battery life extender functionality is provided by the BIOS, and only for some models.
The only way to use it is to "talk" with the BIOS, and this requires additional kernel drivers which are not available for linux.
