Eight or ten hours? I don't take a power cable with me for the day. Would probably be better if I worked out how to set any of the power saving things, this is Debian out of the box. That's mostly showing emacs, I expect it would be worse with a browser.

I'm on a Zen3+ APU (Thinkpad Z13) and TLP has worked great for me. TLP has nice out-of-the-box defaults so you don't need to tweak anything if you'd like, but you may need to disable any existing power management systems, if you're using a full-fledged DE, as they could conflict.

Two cool things that TLP does is allow you to set battery charge thresholds for better battery longevity (I limit mine to 80%), the other being automatically changing the energy performance preference (EPP) in the amd-pstate driver, so if you're on battery you could get it to automatically switch to power saving or balanced powersaving etc. I get an 8-10 hr battery life even with the 80% cap capacity, with several MS webapps running in Edge (Wayland), including Teams and Outlook, VS codium and Firefox running in the background.
