From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Would downscaling a display allow for better battery life? (feddit.uk)

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.
