For years, experts have recommended that the iPhone should turn on dark mode to preserve the life of the iPhone battery their iPhones. If you do not know the reason, the answer is because most recent iPhone models have been upgraded from LCD screens to OLED screens and that type of screen, the black color does not draw any power at all as the screen pixels are turned off in this place. This means that the more black the screen contains, the less pixels are lit, thus saving energy. But what was not clear was how old he is the battery Which dark mode or dark mode actually offers but thanks to researchers at Purdue University, we now have the answer.
recent study
Purdue University researchers tested a number of commonly used apps on popular Android devices such as the Pixel 2 (2017), Moto Z3 (2018), Pixel 4 (2019) and Pixel 5 (2020). The iPhone X that works with an OLED screen will give the same results. The apps that were tested included YouTube, News, Google Maps, Calendar, Calculator, and Google Phone.
How much battery life does dark mode provide?
At normal brightness levels, specifically at 50%, the energy savings were simple, only 8.5% of battery life was saved.
At 30% brightness and dark mode, only less than 5% of battery power was saved.
However, at full brightness, dark mode offers a massive amount of battery life with an astonishing 47% decrease in battery draw.
So unless you need the higher brightness screen, like on a sunny day, Dark Mode will only save a small percentage of battery life, so little that you might not even notice it.
How to turn on dark mode
Turning on the dark mode is easy, you just have to go to the settings on the iPhone and then click on the display and brightness and then choose dark to turn on the dark mode, you can also access the dark mode from the control center and then press the night mode to turn it on or off.
To turn on dark mode automatically at sunset or at a specific time, go to Settings > Display & Brightness and select Automatic. Then click Options to set a schedule for Dark Mode.
