iOS 13 is finally here, bringing a whole bunch of new features to the iPhone. The notable change in appearance is 'Dark Mode'. Apple calls the feature "gives the iPhone a dramatic new way of expressing itself." but what exactly does it do?

Here's how the new Dark Mode works in the iOS 13 release.

Dark Mode is Eye- and iPhone-friendly

First, let's look at the features of the dark mode. Dark Mode is a feature that makes the color base in your screen a darker color, such as black. Not only does it make your eyes less tired when you're looking at the screen in a dark place, but it also saves battery on the iPhone XS and other OLED screens. It is a function that is good for both eyes and iPhone.

There are three ways to switch to Dark Mode. Let me explain in order.

1. Switching from "Settings"

First, you can switch from 'Settings'. First, open Settings and tap 'Display & Bbrightness'. If you check 'Dark', it switches to dark mode immediately.

▲Left: Tap "Screen display and brightness" in "Settings". Right: Check "Dark" in Appearance mode to change to Dark mode.

To restore it, just check "Light" on the same screen.

2. Switch from Control Center

Here's how to switch from the Control Center: Swipe up from the bottom of the screen for models with the home button. Or swipe down from the top right to open Control Center for models without the home button. Then long press on the Brightness bar.

▲Left: Open Control Center. Right: Press and hold the Brightness bar.

Tap 'Dark Mode' at the bottom left of the next screen. The screen changes appearance.

▲Left: Tap Dark Mode. Right: Switch to Dark Mode faster.

3. Set to switch automatically

Finally, here's how to automatically switch to Dark Mode. This setting is convenient because you don't have to switch manually anymore. To get started, tap 'Display & Brightness'. Then tap 'Options'.

▲Left: Tap 'Display & Brightness' in 'Settings'. Right: Tap 'Options'

At this time, you can select two settings: 'Sunset to Sunrise' and 'Custom Schedule'. This time, I want to set it to my bedtime and wake-up time, so I chose the Custom Schedule below. The drum roll comes out, so set the time you want to switch between light mode and Dark Mode.

▲Left: Tap "Custom Schedule" on the left. Set the time you want to switch to dark mode. Right: This time, the dark mode is set from 21 o'clock to 7 o'clock the next morning.

At 21 o'clock, it automatically switched to dark mode. The light mode starts at 7 o'clock the next morning, but you can manually reset it.

▲Left: Home screen in Light Mode before 21 o'clock. Right: It automatically switches to Dark Mode.

If you've updated to iOS 13, you can use Dark Mode right away. It may feel strange at first, but once you get used to it, it may be gentle to your eyes and become addictive. If you want to touch your phone before you go to bed, or if you want to save battery life, you should give it a try.
