tst123Coming from nestle of all people
SquareOh 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
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.
True, but I’ve heard it’s still negligible and almost every dark mode is dark, not pure black.
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
vis4valentineHow is switching to dark mode “more sustainable”
ChozoAssuming 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.

Corporation destroying the Earth blames consumer. Classic.
Hey sure we are extincting orangutans but you can save the planet.
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.
Contribute to a more sustainable experience by not buying shit from Nestlé.

swntwithout being an expert in that, it’s hard to know what’s owned by them and what’s not…
diprount_tomatoWell they own like half of the market so
That reminds me, Lemmy needs a FuckNestle.
I came here hoping someone would link one. That sub taught me so much about their bs.
No time like the present to make the community if it doesn’t already exist!
lemmy.world has one but I don’t know how to link to it
fiahThink of all the breastfeeding children we could save by making white screen black. SMH. Fuck Nestle
HatchetHaroOn 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.
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.
HolzkohlenBut 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.
VediusPollioDepends on the resting state of the LCD.
Saves energy for OLED, not LCD.
Yes for OLED. Not always 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.
Zephyr_0713In 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.
Greenwashing bullshit.
Move to lemm.eeI 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.
I wonder how many users have to switch to dark mode with how many screen time to compensate for any meaningful amount.
Alright 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 dodonut.com/blog/does-dark-mode-save-battery/
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 you’re average use is 80% per day, then that comes out to 8.32Wh per day per phone. That means that the 40% reduction is 3.33Wh.
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 annually.
Let’s put that into some context. The largest Vestas offshore wind turbine is the 15MW V236 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.
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
danLCD 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, do I should have known better… but I’d still like to see numbers on that for smartphones.
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.

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.
What makes you think capitalism is dying? What I see is just the neverending economic cycle
The current version of the system is literally self destructing by destroying the ecosystem. It is also destroying its other external interface: human consciousness, but that is a more complicated discussion.
Not destroying the environment is as easy as researching less polluting and more productive methods, like nuclear fusion. The only thing left to do in that matter is not making it deficitary
Innovation is one of the main things that keep capitalism going, but state-supported or state-ignored monopolies prevent it from happening as people really have no other alternative apart from the monopoly company to buy goods and services
So thanks for providing a great example of the aggressively blinding grip of ideology over our ability to understand our reality. We’ve already broken the ecosphere. A nonexistent technology is not going to save us from the disaster that has already happened. Also the owners of the energy supply are aggressively defending their vastly profitable businesses from any threat to their profits. They’ve done quite well at that, see the comment from you.
The way I see it is this search for money won’t destroy the world completely, but it will probably end up with humans leading their own extinction event and taking lots of other species with us. The world will eventually heal many of its wounds… without us.
Yes sure, it’s only going to massively degrade human civilization.
