Great answer, thanks!

Thank you, @Bennett_Derrico, @Charlie_6 and @Shijikori.

I know this to be true on Desktop and/or Windows. I just wanted confirmation about the Linux/Ubuntu side of things. Thanks!

11th gen does as well, but the wake-up time is a bit of a pain. And I cannot find an easy way to configure the machine to switch from s2idle to deep after a certain amount of time, to save battery.

This sounds intriguing, but I would like to avoid finding myself running 24.04 LTS without it working out of the box, because the hardware is too recent. Wouldnā€™t I incur into this risk? I am using the machine for work, so I am not so interested to be on the bleeding edge, to be honest.

Did a quick Google search, it seems there are still issues to be sorted in the IO but it does boot and work just fine asside from those IO issues.

The power efficiency of the cores is pretty insane, hardware decoding on linux is another story though. On windows itā€™s apparently fine but on linux it uses pretty excessive amounts of power compared to even much older intel systems. Performance wise though itā€™s pretty great, if only they could somehwo iron out that video decoding thing.

Hell the cores are so efficient that sw decoding 720p30 uses less power than it takes my old intel thinkpad with hw decoding.

So, turns out this was with hardware decoding disabled and while on power save. If using balanced instead, the consumption will shoot up to 20W. Enabling hardware decoding reduces the power consumption by about 5 to 8W.
I have observed an annoying behaviour which is when the acpi platform power is set to power-save, the contrast and colour accuracy of the screen will go to utter garbage. I really dislike this behaviour and prefer to take the power consumption personally. I could probably tweak the PPD settings so it does not put the acpi platform power to power-save but still.

Yeah this is ABM (panel power saving). It does save a lot of battery life but can be off putting to some people.
it can be tuned in two ways, both summarized here:
upower / power-profiles-daemon Ā· GitLab

i think iā€™ll be going with the kernel parameter option. thanks!

Heya!

I know this tread has been silent but, has the battery life improved much with all the BIOS/Kernel updates?

Looking at purchasing a FW13 7640u and wanted to hear from users on their recent experience.

Thanks!

There was a pretty big improvement to video playback power use a few months ago, still not where Iā€™d like it to be but it is a hell of a lot better.

90

Thanks.

Is there a link to this?

And how many Watts should the 7640U be consuming now when playing videos on Linux?

(Intending to chuck Linux Mint or another Ubuntu based distro on it.)

91

Maybe not directly but video playback power is discussed here.

Highly depends on what kind of video and what you are playing it back with, 720p 30 it matches the consumption of my t480s now and for higher res stuff it beats it. Still not amazing but itā€™s a solid improvement.

That may be a problem as most of the improvements are in pretty new kernels.

Gotcha. Thanks.
