'Dark mode' in iOS 10 won't blind you with brightness

Apple wasn't kidding: iOS 10 is going to be a huuuge release with a boatload of new useful features.

From a revamped Messages experience, to third-party app integration with Siri, to improved Photos, to a redesigned Apple Music, to all of the things Apple didn't tell you, there's going to be a lot to take in.

Users testing out the iOS 10 developer preview beta have just discovered another much-asked for feature in iOS 10: A dark mode, which turns the interface's bright white backgrounds to black for a less blinding look. 

Dark mode is also easier on the eyes, especially when you're using your iPhone at night with the lights turned off or in a dim place like a bar.

Some Android phones like the OnePlus 3 have a dark mode theme that can be switched on. 

We already knew the new Clock app had a black "dark mode" interface, but it also appears the dark system theme will extend to other apps like iBooks, Safari, Alarm and iTunes.
