On OLED screens dark mode does actually save power. My phone switches to dark mode when I turn on battery saving mode.

It probably doesn't matter much in the grand theme of this, but let's keep the criticism factual. God knows you don't need to make up arguments to criticize Nestle.

[–] Delphia@lemmy.world 28 points 1 year ago

Yeah its not that you (and Nestle) arent right, its that its such a pissingly small amount of energy even on a global scale to be laughable.

Like "Nestle, you arent wrong. You're just an asshole"

It doesnt really matter when its just a gray theme and not black then on oled the pixels are still on

[–] jarfil@lemmy.world 5 points 1 year ago

They still use less power for gray than for full white... so it's "something".

It should be noted that it’s on light mode by default, then they give you the pop-up to turn on dark mode

It only really does anything if the pixels can turn off completely. So the dark theme would have to feature full black backgrounds, not dark grey or anything like that.

This is a myth. The darker the pixels, the less power an OLED display draws.

But realistically, how much energy is really being saved on a global scale? If everyone who visited the nestle site all used dark mode, would it save more energy than a single car ride to work?

The whole Nestle guilt-tripping you thing is stupid. I’m not arguing with that.

[–] Virkkunen@kbin.social 4 points 1 year ago

Definitely not nearly enough as if a company such as Nestlé acted to actually become sustainable and green, but it's all about guilt tripping John Smith into making his life more miserable on the fake promise that he's actually helping save the planet while companies keep trying to destroy it.

If you work from home, maybe... /s

[–] Virkkunen@kbin.social 3 points 1 year ago (1 children)

That's not true. You can go upwards to 33% grey and it'll have the same effect as completely black if I recall correctly, but the all around energy saved by using dark mode isn't anything to write home about, really.

The Purdue study found that switching from light mode to dark mode at 100% brightness saves an average of 39%-47% battery power.

That's a lot actually. Only that much outside on sunny days, but still.
