This is the most pathetic attempt at greenwashing I have ever seen.
Wow. What their really intimating is #ScorchedEarthMode

I wish it was that easy, but nestle has taken almost 80% of global middleman positions in the food market, they have become a pseudo monopoly in the food industry.
Remove the pseudo
Everywhere you look end stage capitalism is enshittifying itself. The neolibs, having insisted that There Is No Alternative, are confronted with their system in full and manifest self destruction.
I wonder how many users have to switch to dark mode with how many screen time to compensate for any meaningful amount.
Edit: I tried updating this, when I submitted sh.itjust.works was down and I lost it… the edit that is. Anyway I have now updated some grammar and put in some more context AND a tl;dr at the bottom. All for the low low price of my hyper focus.
Alright, it’s math time.
A quick google comes up with this blog post, which I haven’t vetted or even read at all, it just has a table with some stats https://dodonut.com/blog/does-dark-mode-save-battery/. I should probably also mention that I am going to use the most impressive savings in the following. Actual savings may be as little as a 4th.
Apparently going to dark mode with 100% brightness provide a net saving of 40% on a pixel 2. Let’s assume this is universally true for all OLED and AMOLED displays, LCD users won’t see a difference, neither will CRTs but … I don’t think that I’ve heard of a CRT display on a phone.
40%? That sounds like a lot, doesn’t it?
Well yes and no, in relative terms it’s impressive, but it really depends on absolute terms. So how much does a phone use? The pixel 2 from before comes with a 10.39Wh battery, let’s assume an average use of 80% per day, then that comes out to 8.32Wh per day per phone. That means that the 40% reduction is 3.33Wh daily.
Is that a lot? Depends, if your only power source is a potato with a bit of copper and a galvanized nail, then yes, otherwise no.
Over the course of a year 3.33Wh a day comes to 1.215kWh.
Let’s put that into some context. The largest Vestas offshore wind turbine is the 15MW V236 https://www.vestas.com/en/products/offshore/V236-15MW. It can produce 80GWh annually. With the saving of 1.215kWh per phone, then for every approx 66 million OLED phones, we can skip erecting one offshore wind turbine.
But let’s look at a global impact. As of yesterday there were 8.05 billion people breathing on the planet. Let’s say they all achieve the maximum saving of 1.215kWh annually. That’s 9.78TWh. Presently there’s a handful of projects planned with the V236, https://www.offshorewind.biz/2023/04/03/vestas-15-mw-prototype-now-at-full-throttle/, totalling 7.3 GW, 486.6 units (I’ve got the figures for each project and added them up, so the number of units is an approximation) or 38.9TWh annually. So get everyone to achieve maximum saving, with technology most doesn’t have, and we can save a quarter of the planned pre-order of a turbine model that isn’t even done with testing.
tl;dr: dark mode does save power, but at best its effect is miniscule, and realistically utterly insignificant.
1.215kWh, 18p of electricity per year. Beers on me folks!
Wish my power was that cheap
I don’t think that I’ve heard of a CRT display on a phone
BALLER. samsung i hope you are listening
I hate this shit. Just make darkmode the default.
I already have it as default in my whole computer so
What the fuck does that even mean lol. I didn’t think dark mode even did that?
It kinda does if your screen is OLED. The black pixels are actually turned off on OLED screens.
On other type of screens - like LCD - the backlight is always turned on
Yep, but then we are talking about actually black backgrounds, which is normally a big no-no in UI design.
A black pixel in an LCD is in the ‘on’ position with voltage applied. So dark mode uses more power on an LCD, though the number is small.
With OLED, yeah it is indeed more sustainable cause less energy usage but damn it’s a stupid thing to say and remind from their end. It’s already implied

You can be sure that they are counting every hypothetical drop of energy saved this way and taking credit for it to their benefit somewhere.
Oh the irony… 🤣
What does this save, like a milliwatt per year? One of the stupidest things I have ever seen.
They can’t do any good in the world. This is the best they have to offer.
Sending the JavaScript to do this literally uses more electricity than this saves.
Plus all the energy used in developing the feature in the first place. What a crock.
This is classic. Corpos that are the biggest polluters are also the ones that push hardest on the idea of “carbon footprint”
The more they can convince people that climate change is their fault, the less likely people vote for a government that will regulate the corpos
Don’t worry, they’ll vote for a government that regulates the people and not the corpos
Back in CRT days, the difference between full white and full black could be as much as 100W. Before dark mode existed, people developed sites like Blackle to reduce the power usage of Googling.
Traditional LCD screens actually use more power to make black.
OLED screens might save a tiny bit of power though.
It’s only going to save power if you’re using an oled, since for most lcd screens the backlight is on whether you display black or white.
All my websites are jet black, and the black is only really black on my phone which has an oled screen.
Either way, it’s just greenwashing. These companies are only pretending to give a crap so they can get brownie points with people who can’t see what they’re doing.
Most lcds take a tiny bit of current to darken a pixel I think. The ground state would be white and power is used to get the lcd in the state where it changes the lights polarization to get it blocked by the polarization filter in front of it
I assume that would depend on the polarization of the screen. I wonder which is more common?
Yes, I think it’s this way around because precision is higher at higher power, so the minor deviations close to no voltage applied are hidden in minute white variations, while near blacks are way more precise. But don’t quote me on that
First of all you guys should be using dark mode already. I have a firefox extension that does it on all sites automatically. How tf do you live with that blinding white flatscreen in your face?
I mostly deal with it by not browsing the internet in a cave. I get some natural light. You know, pull back the curtains on those windows and let the sun shine in.
It works wonders for many hours of the day. After the sun sets… well, I too have an auto dark mode extension. It turns dark mode on a few minutes after sun set.
How is switching to dark mode “more sustainable”
Assuming it’s using pure blacks for its dark mode and you’re using an AMOLED display, it could save a bit of power, depending on how frequently you have that page open and how much screen space it’s occupying. AMOLED displays illuminate each pixel individually, and pure blacks mean those pixels are just turned completely off, and aren’t consuming any power.
The difference is pretty marginal though, to be perfectly honest. You might see some improvements to battery life on your phone using dark mode, but that’s pretty negligible for most use-case scenarios.
Nestlé lives in dark mode.
Dark Mode. 0 trans fats and no artificial colours or flavours.
