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:

• 6.3
• 6.4
• 6.5
• 6.6

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 :)
