According to a Purdue University Study dark mode can save 3 to 9% of your battery if you’re on auto brightness. Let’s say your average phone uses 15Wh per day (5.475 kWh per year). Let’s say 5 billion people use smartphones. That’s around 30 TWh for total yearly smartphone consumption.
So if everyone was using dark mode, it could save around 0.8 to 2.5 TWh a year in the best case scenario. But that is if everything on your phone was dark mode. Not sure how much time people spend browsing websites percentually.
That’s around 0.1 to 2.7 times the daily electric energy production of all nuclear power plants.
The world electricity production is around 23000 TWh per year, so you could save around 0.0036% to 0.01% of yearly energy consumption by switching everyone to dark mode.
Such impactful, much environment, wow
that study talks about oled displays btw, shit’s not gonna change for regular backlit devices
word of the day is greenwashing, fucking engrave it into your brain – get the words for the phenomena and all that shit
Now calculate how many nestle wells that steal people’s water that makes.
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.
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.
