There is no dark mode
iOS needs a dark mode now more than ever.
OLED displays, like the one packed into iPhone X, are far more efficient when displaying darker images. That’s because unlike LCD displays, OLED displays have the ability to light each pixel individually. And black pixels don’t need to be lit at all.
That’s why the user interface is so dark on Apple Watch; black backgrounds use a lot less energy, and this helps make the most of battery life. But we still don’t have a dark mode option in iOS 11, and that needs to change.
When you consider how big the iPhone X’s display is, a dark mode could dramatically increase battery life. All those white backgrounds are taking up too much power.
