It’s important to know how to enable dark mode on iPhone, as anyone who has ever checked their phone in the middle of the night will agree. Bright screens like the 2,000 nit display on the iPhone 14 Pro are great in a well-lit environment, but in the dark, they can be overwhelming to look at and cause eye strain. 

To avoid this, you can turn down the brightness of course, but a white theme can still cause the screen to be too bright for comfort. That's why it's good to know how to enable dark mode on iPhone. This will turn your phone's theme to primarily dark, which further reduces the effects of bright, white and blue light, in turn making your phone more pleasant and comfortable to use in the dark.

Personally, as someone who seems to get headaches easily, knowing how to enable dark mode on iPhone is a must, especially if I'm going to be staring at a screen for long periods of time. Thankfully, enabling dark mode on iPhone is easy to do, and we'll talk you through it. What's more, as you'd expect from some of the best phones around, iPhones can even automatically switch between dark mode and light mode based on the time of day. We'll show you how to enable that too. 

Without further ado, here’s how to enable dark mode on iPhone.
