Hello. I know this isn’t completely related to Linux, but I was still curious about it.

I’ve been looking at Linux laptops and one that caught my eye from Tuxedo had 13 hours of battery life on idle, or 9 hours of browsing the web. The thing is, that device had a 3k display.

My question is, as someone used to 1080p and someone that always tries to maximise the battery life out of a laptop, would downscaling the display be helpful? And if so, is it even worth it, or are the benefits too small to notice?

    I don’t think it would matter that much since a desktop at 3k is very similar on modern hardware to a desktop at 1080.

    But I’d be interested in someone who had the hardware to test this. Right now I use my laptop for school work, and in trying to squeeze every ounce of battery life I was running my display at 45hz instead of 60hz. I had a free day during the summer so I charged it up, ran a YouTube video on repeat and timed the battery life, then changed the display frequency and it was like a 2 minute difference. I also tried it while running a second 1080p monitor through hdmi and the difference was something like 10 minutes. Like, so small a difference or didn’t matter.

    I don’t have the data sheet anymore so these numbers are anecdotal etc etc YMMV. The biggest change for me was buying a 65w PD battery bank and keeping that charged in my bag.
