Daylight saving time ends on Sunday, November 1, and sunset comes about an hour earlier on the clock right after. That means more of your evening screen time happens in the dark. Night Shift shifts the colors of your iPhone display to the warmer end of the spectrum, which Apple says makes the display easier on your eyes. Here's how to turn it on and schedule it, following Apple's iPhone User Guide and Apple Support.
How Night Shift decides when to start
Apple says Night Shift uses your device's clock and geolocation to work out when it's sunset where you are. Then it shifts the display to warmer colors, and in the morning it returns the display to its regular settings. By default, Night Shift runs from sunset to sunrise.
That's the useful part around November 1: if you use the sunset setting, the schedule follows the earlier sunset on its own.
Turn Night Shift on or off manually
Apple notes manual Night Shift is helpful when you're in a darkened room during the day, like a movie afternoon with the curtains drawn.
- Open Control Center.
- Touch and hold the brightness control.
- Tap the Night Shift button.
Schedule Night Shift
- Go to the Settings app on your iPhone.
- Tap Display & Brightness, tap Night Shift, then turn on Scheduled.
- Tap From, then select Sunset to Sunrise or Custom Schedule.
- If you choose Custom Schedule, tap the options to set the times you want Night Shift to turn on and off.
Set the color temperature
On the same Night Shift screen, drag the slider below Color Temperature toward the warmer or cooler end of the spectrum. Try it in the evening, in the room where you actually use your phone, so you see the real effect.
Pair it with Dark Mode
Night Shift changes color temperature; Dark Mode changes the interface to a dark color scheme. Apple's guide lets you schedule Dark Mode too:
- Go to Settings > Display & Brightness.
- Turn on Automatic, then tap Options.
- Select Sunset to Sunrise or Custom Schedule.
Together, they make a phone that gets warmer and darker as the evening goes on.
A post-time-change setup
- Before November 1: turn on Scheduled and choose Sunset to Sunrise.
- First dark evening: set Color Temperature to a level you like.
- Movie night: turn Night Shift on from Control Center.
- Wallpaper: a darker image looks more natural with warm evening colors.
Troubleshooting
- Night Shift won't turn on: Apple says some display accessibility settings, including Invert Colors, Grayscale and Increase Contrast, might turn off Night Shift.
- Schedule seems off: Sunset to Sunrise depends on your clock and location, so check both.
