At the moment, the dark mode has become, the night mode or the dark mode is essential for most of us as users, as soon as we buy a new phone we activate the dark mode from the settings and even once we download a new application we activate the dark mode inside it and maybe if the application does not support the dark mode, some of us wipe it completely And looking for a replacement! So is dark mode a good thing, whether for the human eye or for the iPhone battery? This is what we will know now ..
Is dark mode saving your battery power?
The short answer here is that the dark mode will actually save you energy if your iPhone works with an OLED screen, and this applies to the iPhone X / XS and 11 Pro phones. This type of screen, whether it is OLED or what Samsung calls AMOLED, makes the most use of this dark mode because the black pixels are actually off and do not get any power from the battery!
OLED and AMOLED screens deal excellently with the black color and the matter has reached that Google itself has started promoting dark mode as a way to extend battery life on Android phones, including its newborn Google Pixel! As for LCD screens, they are not affected by color like OLED screens, and to find out the reason, this is due to the way the two screens work:
◉ OLED screens work by lighting each pixel independently; If the dark mode is enabled, then here it means black pixels, meaning they are off, meaning they do not need power, so energy is saved.
◉ LCD screens work by means of a layer that displays the image and behind it the illumination of the entire screen. So the black color of any part does not affect as clearly as the OLED. Because in the end the backlight will work.
The next two pictures illustrate how OLED works in the first image and LCD in the second image.
Is dark mode better for your eyes?
In the event that you are reading a text, it is best for you to have the text in black on a white background (as in the iPhone Islam), as the matter here depends on the properties of color, lighting, as well as the human eye. White is able to reflect all colors with ease which means that exposing your eyes to it will not make her have to widen the irises on her shutters! Whereas, the black color is completely opposite to these characteristics because in reality it does not reflect any colors in normal cases, which requires more effort and a wider iris to absorb it.
As you can see, writing in white against a black background is a very bad choice since it needs you to significantly expand your iris! But let's agree that the above was about reading, but for staring and for frequent screen use, a black background is best! So perhaps your ideal choice is to use white wallpapers when reading and black wallpapers when browsing normal!
We go back to the battery .. What is the effect of the dark situation on the battery of the iPhone-iPhone?
The dark mode appeared on iPhones beginning with version 13 of the iOS operating system, and since then we all have loved it, despite our lack of precise awareness of the extent of its impact on the battery in terms of numbers. Here is an experiment by the PhoneBuff channel, which showed how dark mode affects battery performance, and this was for the iPhone XS, which, as we know, comes with an OLED screen.
The experiment was done through robotic arms that continued to use the phone on applications such as the Messages app, Google Maps, YouTube and many more, and the experiment was done on the phone while activating the dark mode again and again while deactivating it.
The results were surprising to a large extent. This is where the phone that works without dark mode was completely discharged from 100% to 0%, while - in the same trial conditions - the phone that works with the dark mode reached 30% and did not run out of charge!
This is while the experience was done on the phone and it is at nearly 200nits brightness, but this does not matter to us as the conditions were completely similar on the two phones! Of course, the more apps that provide you with dark mode and the more you use them while activating dark mode, the more energy you can save!
