The docs/wiki are also great and has lots of charts illustrating what each setting does: On my old Ryzen laptop, I have it set to run `ryzenadj -f 48` when I go on battery, which limits the temperature below my laptop's fan hysteresis for a very efficient and totally silent system, and `ryzenadj -f 95` to set it back, but you can also adjust most power and clock parameters (not everything works on Ryzen 6000 yet, but the basics should). RyzenTuner: A GUI tool that supports adjusting the power limit of Ryzen mobile processorsĪMD does automatically switch to a 'power saving' profile on battery that lowers power consumption significantly vs on charger, but if you want, you can tweak even further with a fantastic tool: - it's a simple CLI util so easy to set up w/ udev rules to run automatically.(TLP has run-on-ac and run-on-bat commands so you can easily set your defaults based on whether you're plugged in or not (udev can see power events too). On Windows, 3rd parties have been working on a utility called AATU to improve performance and longevity: Īnd on Linux, I used all the time for my preferred use cases (eg, setting the temp limit below when fans turn on to get a completely silent laptop on battery, lowering max power limits if I wanted to hit a certain amount of battery life, etc). On iGPU mode, the battery life tests for idle and wifi web browsing seem pretty good in Windows. I don't know about your workload, but in you case you ever wanted to poke around, one thing that might be worth looking into is to see whether the MUX switch (only accessible in Windows) is on its dGPU-only mode. Besides the short battery life, I hope your new laptop is treating you well otherwise!
