Issues with power usage

powertop reports an idle power usage of 7-8W. I have no idea what’s using the power, because the cpu is at <1% usage and the gpu is at ~5% usage when idling. Powertop says the wifi adapter is using 10W (which is more than the total power usage?), so I don’t think I can trust anything but the overall usage in there. The battery is draining fast enough to suggest 7-8W usage, though (only 4-5 hours of battery life idling).

I am using a sdd and wifi card from an old laptop, but I don’t think they could drive the idle up that much.

I have configured the correct settings, I will attach the output of tlp-stat as well:

Screenshot of powertop and intel_gpu_top for good measure. The power usage can also get to 10W under light usage and 15-20W under load, which I don’t think is normal either. I’ve tried running the system on a different laptop and had the same issues, so it’s a system issue rather than an issue with the framework laptop. Powertop has also switched to saying the display is consuming 11W now, which is definitely not possible

I’ve narrowed it down to the idle states of the CPU - I’m only reaching C3 when idle for some reason (unless the Pkg section is wrong and I should be looking at individual cores), despite the CPU idling at 1% usage, 2 cores at 500mhz, and the rest at 1000mhz. I also got GPU idle down to 3-4%, even with all the blur effects, although I don’t know if it they matter since pstate is a thing and the image is static, blur or not.

Maybe you’ve already made more headway with this, but if not, here are a few suggestions based on my own recent attempts to get handle on power usage via tlp & powertop:

  • If you haven’t already, run powertop -c to calibrate [see the bottom of the Arch wiki for details].

  • Make sure everything is set to “Good” on Tunables tab of powertop. [On your tlp-stat readout, I noticed your dirty_writeback_centisecs set at 6000. That’s something powertop is always telling me is “Bad” and wants to adjust to 1500.]

  • Do you have the Intel PCH Thermal driver installed? That seems to be the one out of all the various Intel power management drivers that works with Tiger Lake.

  • Since you’re systemd, you might get something out of auto-cpufreq [which according to this post works well in tandem with tlp].

  • Is it possible that Brave/Electron were the culprit for the backlight usage in your screenshot? Although, that didn’t seem to be effecting the overall battery discharge rate as much.

Good luck getting to C10 nirvana. Maybe post to the Linux battery life tuning thread if you don’t get more feedback here. I’ve found useful suggestions there.

I’ve found that using s2idle (see /sys/power/mem_sleep) will put it into a state where it will never go past C3 for some reason. Rebooting or using “deep” seems to fix it, allowing for C10; alas “deep” takes about 15 seconds to wake from sleep for some reason (maybe depending on your exact configuration).

I have already calibrated powertop many times. As for dirty_writeback_centisecs, iirc it’s the maximum time before data is written to disk, in centisecs, so what I’ve set via TLP is more aggressive than what powertop wants to set it to (60s vs 15s).

I’ve tried auto-cpufreq, but it decided to just have the cpu constantly turbo to 3ghz (???). I think TLP’s constant 800mhz is better than that lmao

I have also done these tests without any apps open and in a tty, and the lowest I can possibly get idle power consumption is around 6W in a tty with nothing else running.

As for the driver, how would I go about installing that? Can’t seem to find it anywhere

Yeah, that’s one of the first things I did after reading the linux thread on the forum

Solved.

Issue was that I was running linux-zen, strangely. With linux-zen, the CPU wouldn’t get past C3 and idle power usage was 7-13W. With regular linux, the CPU reaches C8 and idle power usage is ~5W. Strange that linux-zen did that, but ok ig
