From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Massive battery life improvements on AMD over the past year (lemmy.ca)

AMD has been on a roll over the past year making significant strides in power management across the Linux stack.

Most of this work is centered around support for p-state.

To take advantage you should run a newer Linux kernel. Here are some of the improvements from each recent release:

Use power-profiles-daemon 0.20+ which sets the appropriate p-state driver based on the selected battery profile.

Upcoming changes:

More kernel improvements
Firmware and kernel module updates (distro dependendent; e.g. Debian)

Kudos to AMD principal engineer Mario Limonciello for driving these changes across the board!

This is one advantage of increased competition (e.g. from the Apple M series); the entire ecosystem is pushed forward.

I am personally benefiting immensely from these improvements on my new Thinkpad t14s with AMD 7840U (battery life going from 4-5 hours to easily 10+ hours).

Finally we don't have to settle anymore for underwhelming battery life on Linux laptops :)
