Just cause it has a low Wh/GBw doesn’t mean it has particularly good idle power but in this case it very likely isn’t the issue.
You may want to check if apst is working right (item 4 here)
Thanks for that.
Yeah, seems to be enabled.

I’ll try pulling one of my DIMMs to see how much that reduces consumption. If it’s significant, maybe the RAM’s just not a good fit for this machine.
Edit: Yeah, if anything, using half the RAM seems to increase power draw by 0.2-0.3 watts at idle. Maybe it’s caching more, though I don’t think I’m running particularly many background services either.
Good, then it’s unlikely to be the ssd.
In my testing that made barely enough difference to be measurable but nowhere near enough to be worth cutting memory bandwidth in half.

So that probably rules out both of the non-Framework components, which is good to know.
Then with the other hardware being the same as the 7040U machines running Windows at 2.5W, there has to be something going on in software.
Not that that’s particularly new information, but it looks like some people are getting slightly better power performance even on Linux?

2.5W?! Damn, lowest I got with the screen on was like 2.7.
You got PPD or TLP running right?
I am personally pretty content with the power consumption on Linux (appart from the borked hardware decoding consumption)

PPD, yeah.
I’m getting 4.5-5 at best with the screen set to absolute lowest and running nothing at all.
Edit: Found the link. 2.5W idle is from an i7 Framework from a couple years ago. Both Windows and Fedora.
So… yeah, I feel like this machine could do a bit better.

Yeah 2.5 is also something my old t480s could do with min brighness under linux. But I am ok with 2.7 min idle especially since min brighness on the framework is a bit brighter than on the t480s.
Could always be better but mine does pretty ok as long as there is no video playback involved.
Got it down to 3.2 idle with a few things:
- TLP helps alongside PDD
- powertop --auto-tune
- Docker, even with no containers, causes interrupts, so that was pretty big
- Switch from xmonad on X to Hyprland on Wayland (Wayland’s power draw seems to be basically the same as text mode when idle)
- Remove SD card reader card, which draws power even when it’s vacant
Video on Firefox seems to be a lost cause at the moment. Forcing vaapi causes intermittent juddering and is still not all that great of an improvement.

Same here, ended up returning the single 32GB Crucial stick and keeping the 2x16 I had before
But those 0.3W XD

You could also do this in KDE power management settings. Are you just giving a general solution for those not on KDE or…? Why udev?
3.5W with 46 tabs (6 active over 3 windows) on Firefox using gfx.webrender.all in about:config! Not bad!

Power Devil’s permissions do not allow it to write to the sysfs. So the scripts do not work. udev rules run as root and they can also trigger on power state change.
PPD would be a better solution. I personally wrote a power manager in C++, because I felt like it (it’s very basic and has basically no functionality but it was a nice little project).
More savings: Down to 3.1W idle swapping the AMD/Mediatek radio with the Intel AX210.
Also much better wifi signal (90%+ vs 60) and better speeds.
Don’t quote me on this, but I think I read somewhere that AMD and Mediatek have an arrangement where manufacturers are required to sell the CPUs and wifi chip together, so it may that the Framework is being forced to sell the AMD with a subpar radio.
Definitely another point in favor of a thoroughly upgradeable laptop, in that we have an escape hatch out of that kind of political nonsense.
Is this compared to your post around 10 days ago where you were down to 3.2w idle so changing out the card is delivering better performance with 0.1w idle power savings?
The trying to get a sense of scale (IE what are the biggest things you’ve found have made a difference)?
Sorry, yeah, that’s with a bunch of tabs open. 2.8-2.9 idle.
It’s hard to say what I did was the biggest… they were all in the range of a couple hundred milliwatts. Disabling Docker seems to have been big, maybe 400mW or so, which is a bit disappointing because it seems to suck power (specifically it causes interrupts) even when I have no containers running.
Also, slightly unrelated, but I’ve given up on Firefox because it seems to go glitchy with hardware video decoding enabled.
Maybe switching to Podman is an option for you? It doesn’t require a daemon to run, therefore when no containers are running nothing at all is running.

Oh you’re right! good idea, thanks!
Reviving this thread now that we’re a few firmware updates further than October '23.
I’m currently on the fence about buying the FW13 AMD mostly because of battery life and not being able to find if FW finally delivers timely updates through LVFS(without it being in beta or something or suggesting to boot Windows to update firmware).
Did general battery life improve in the meantime?
Was the video playback issue fixed by firmware or AMD updates?
I’m planning to run Ubuntu 24.04 but need to be sure that the FW is about as efficient as my current 3 year old Lenovo laptop with a Ryzen 4800u(with currently 79% battery left I still have an estimated remaining 7 hours and 20 minutes left).
Thanks in advance!
Overall, I get 8-9 hours (conservatively) while coding with:
- PPD in balanced mode and a dark theme (ABM helps).
- Intel (ax210) wireless card with power power saving enabled.
- Arch Linux, Linux 6.9.2 (i.e., latest everything).
- Expansion Cards: HDMI-v3, USB-A, 2x USB-C.
I tend to run out of energy before my laptop does at this point.
However, no, the video playback issue has not been fixed and I’m not holding my breath on that one. If you’re going to be watching video on Linux, you’ll halve your battery life. And that’s with X (no fractional scaling) and either VAAPI or Vulkan.
