11th Gen + Linux + Suspend (s2idle): Is anyone able to get a sub-0.5w power consumption?

Framework Laptop 13
1

I’m still on the 11th gen board, with BIOS 3.22, USB-C cards only, 2 x 32GB. With Fedora 42 and Ubuntu 24.04 LTS, I’m still unable to get s2idle to sip sub-0.5w during suspend. What am I missing here? It’s been 4 years, and I was hoping that Framework and / or the Linux community could have this addressed.

The only other ‘workarounds’ I’ve seen seem to be going with either:

  1. S3 / deep, but with longer wake up time. (like 20 seconds+); or,
  2. Leverage suspend AND (then) hibernate, never suspend alone. Which still means the suspended state still sips more than it should.

[TRACKING] High Battery Drain During Suspend
2

I have NixOS installed on my 11th gen intel machine. It has 2*16GB ram. Recently updated to 3.22. Using s2idle and overnight less than %1 per hour battery is consumed which sub 0.5w. It has samsung 970 evo 1tb if that is a factor.

Btw, I thought 11th gen supported up to 32GB.

I wonder if that’s a factor. I just gave NixOS a go, but I didn’t reach the same outcome. Was there any additional / specific configuration done on your system?

64GB is the max.

I use Hyprland, which is supposed to be light. I have also installed nixos-hardware modules which applies hardware specific optimizations.

Thanks for the pointers.

Heading over to the NixOS thread and guide:

Sure, hope it works well.

here is my config if you wish to check.

Just getting back to this….and OMFG….it bloody matters, in my case:

Tried these, which didn’t work even with a fresh installation of NixOS + nixos-hardware:

  1. Adata SX8100
  2. Adata / XPG GAMMIX S70 Blade
  3. Intel SSDPEKNW512G8

All of them seem to have prevented the system from entering a decent low power state.

I had to go with the default SN850 (with just a fresh NixOS installation + nixos-hardware) to get the power consumption down during suspend.

So, lesson learnt, don’t cheap out on SSD.

Glad to hear you found the source of the issue. I have preferred sn7100 instead of sn850x in my recent order for this exact reason.

I just went out and got an SN7100 1TB. Going to see if there’s any energy benefit coming from the SN850 1TB, and the SN850X 1TB. Will report back.

Currently testing out Idle Powered On (NixOS, 6.16 kernel, Plasma, 20% brightness, wifi on / wpa3, added nixos-hardware, sleep disabled). Then I’ll test suspend energy consumption.

Update 1: Idle Powered On

Doing the suspend (s2idle) test now.

Update 2:

Over the course of 312 minutes, battery lost 3.157Wh. So s2idle is at approx 607mW.

Good results, thanks for sharing.

Going to compare those numbers against Windows 11, see if they’re on par with each other.

So, on the Windows 11 Pro side, normal installation, plus the driver bundle, changed standbybudgetpercent to 40%. It slept for 8 hours and 14 minutes. During that period, it was averaging at 716mW.

Nice, NixOS won this nicely, both with fresh installation and minimal configuration changes.
