Nestlé’s ethics already went to dark mode.
I hate this shit. Just make darkmode the default.
I already have it as default in my whole computer so
I want the amoled black. Not the grey one that they call dark.

Depending on what kind of screen you have it makes no difference anyway.
On LCD displays dark mode actually uses more electricity; the brightness is always there, and you need to power the liquid-crystal layer to block that light to result in darker colours.
This whole myth about darker screens saving energy goes way back to the old CRT days when it actually did save some energy.
Yall remember Blackle?
Many phones have OLED displays, which physically turn off the pixels in black areas. Since the site is on mobile, it does make a bit of sense.
But then most dark modes aren’t pitch black. I guess it might save a bit of power by just being at a low brightness. Anyways I need my dark mode and also night mode.
Less brightness means less light emitted by the diodes means less power is used. They may not turn off, but they still use less.
Fun fact! Many OLED displays dim the whole image not by making the diodes dimmer, but by pulsing the diodes fast enough to match the desired brightness of each pixel.
You can test this by taking your OLED phone, pulling up an image, and then waving it around at different brightness levels; the observed image would become blurry at high brightness levels, but would separate into distinct “frames” at lower brightness.
I’m not sure if every OLED does this; just from the phones that I have used.
Depends on the resting state of the LCD.
Saves energy for OLED, not LCD.
Yes for OLED. Sometimes for LCD.
From what I understand, LCDs can have a resting state that will either stop light, or a resting state that will let light through. The backlight remains on, but a panel that natively blocks the light will require less power when showing black.
In case you are using an OLED screen or one of its variants, the difference is noticeable since they turn off the pixels that are black and, therefore, less electricity is consumed.
Oh the irony… 🤣
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
True, but I’ve heard it’s still negligible and almost every dark mode is dark, not pure black.
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
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.
Greenwashing was never about effective practical solutions. It’s always been gaslighting and marketing.
It’s almost comical, especially coming from Nestlé
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
Sending the JavaScript to do this literally uses more electricity than this saves.
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
Throughline (podcast) did an episode on corporations off-loading responsibility for stuff like this onto the populace.
Found it: episode is called “The Litter Myth.”
Plus all the energy used in developing the feature in the first place. What a crock.
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.
This is very strangely phrased. The “sustainable experience” to me suggests my personal experience like eye fatigue even tho “sustainable” is not the most fitting word for that. But the “contribute” suggests ecological subjects. Whatever it may be it is ur average corporate paternalism nonetheless.
Edit: Maybe im off here it may solely be greenwashing, the eye comfort take doesnt really make sense.
They try to greenwash, just just end up applying more clearcoat.
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(that was false, I’m an idiot) … 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
In general at least here in the UK power prices are back to what they were before all the unpleasantness with russia started. Obviously will vary elsewhere.
Czech here, 30p GBP/kWh
I wish the beer was that cheap.
Thanks for your effort
I don’t think that I’ve heard of a CRT display on a phone
BALLER. samsung i hope you are listening
Linus would be ecstatic - especially if they threw in a 5700xt and a 5600x in there as well. Come to think of it, probably not the best thing ever to have a 300W heating element in your pocket in case you want to play candy crush on the can.
LCD users won’t see a difference, neither will CRTs
Dark mode does save power with CRTs. They shoot an electron beam into phosphors in order to display stuff on the screen - having a mostly dark screen means fewer phosphors need to be excited.
I’m not going to argue about that with you, I’m so old I was online years before google, so I should have known better… but I’d still like to see numbers on that for smartphones.
what even is a “more sustainable experience”
dark theme › slower battery usage › charging less often › less electricity usage › less coal power plants › less emissions › solved global warming. It’s simple really. Now you just need to turn off the tap while you brush your teeth.
Now you just need to turn off the tap while you brush your teeth.
Do… Do people leave the tap on? Why?? That doesn’t make sense.
Yes of course howelse am i gonna shower?
Exactly, I think it was a strawman made up by corporations so that they would look good trying to discipline people (put them on a moral pedestal)
Believe me, it’s not a strawman. My friend does this, and I have tried many times to stop him from doing that, including trying to reason with him or just turning it off for him. He still does it. Not that he refuses to turn off the tap, he always agrees to remember to turn it off but just never remembers to do so.
Do they actually explain that anywhere on their site, besides the short sentence from the pic?
🤷 But well pointed out, I did have to make a lot of assumptions to come up with this explanation. I can’t see what else they’d be implying though
Yeah, I’m assuming that’s the implications. Just more of “unplug chargers you aren’t using” and other now useless advice from 10 years ago before regulations were introduced/new evidence was found
In case anyone’s wondering, unplugging chargers apparently only saves 0.5% of household energy use. And on this page about saving electricity on computer use, “turning on dark mode” doesn’t even make the list of recommendations. Basically the main thing recommended was “put your computer to sleep when you’re not using it.”
The dark theme on their website isn’t even completely black… It’s a dark grey. The power consumption difference even on OLEDs would be very little, if anything at all.
Only on OLED phones
Most important point: …and anyone that thinks its unnecessary is destroying the planet. And that is a fact.
the one you can “contribute” to …

Nestle like world going dark. This is just a hint. They loot all water and world does dark.
