Hi, Is there any function in the Linux kernel that control the charging/discharging of the battery to provide better lifespan ? (add some years to its life ?) For Laptops, it is better to extract the battery from the Laptop when the computer will be on power for a long period. I ask if the kernel can do such control without the user intention and in an automatic way. Some BIOS provide to the user to select whether to block the battery charging to 50% to make it stand for more time. And Many people (like me) forget their laptops on power until the battery no more can hold energy after 2minutes of no power.
On ThinkPads, tp_smapi (not in the kernel.org kernel) can do it. I'd like to see this feature standardized in sysfs.
