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?
Maybe if it allowed you to switch to integrated graphics versus discrete, putting the GPU to sleep.
For just browsing, even integrated graphics has been plenty since the beginning of the internet, maybe with some exceptions when Flash gaming reached its pinnacle.
That might save a bit of power, but your dedicated GPU is usually in an idle/powered down state until your compositor gives it specific applications to accelerate. for Nvidia laptops this is what the PRIME/Optimus feature does.
Even back when I was in the laptop-repair game, this is the kinda stuff people would expect me to know about their stuff that I hated. I saw too many features come and go over the years to keep track of even half of it on behalf of others.
Using the iGPU might save power but the resolution doesn’t need to be turned down for that
Depends on the iGPU, but this being a damn near brand-new laptop, I’m sure you’re right.
