Dark mode, first introduced in iOS 13, provides a dark theme that is easier on your eyes, especially at night. If you want your iPhone to automatically switch to dark mode at sunset, all you have to do is go to the Settings app. Here’s how to set it up.
First, open “Settings”
In Settings, tap Screen & Brightness.
Under the ‘Appearance’ section, where you can choose between Light and Dark modes, tap the switch next to ‘Automatic’ to turn it on.
Once “Automatic” is enabled, an “Options” setting will appear just below it. By default, your iPhone will keep light mode activated until sunset or dark mode until sunrise. Tap on ‘Options’ to confirm it.
On the “Appearance Schedule” page, make sure “Sunset to Sunrise” is checked by tapping on it.
If you are ok with the sunset to sunrise schedule, you can exit the “Settings” app now.
Otherwise, if you want to change the schedule to custom times, tap “Custom schedule” on this page and select the times when Light and Dark mode will activate.
Then close “Settings” and you are done. If you select “Sunset to sunrise”, the light mode will be activated at sunrise and dark mode will be activated at sunset. If you have chosen a custom schedule, Light and Dark mode will automatically activate at the times you choose. Never underestimate the power of dark mode to reduce eye strain.
