How to use Night Shift on iPhone and iPad

iOS 9.3 Night Shift mode teaser 003

Night Shift is among headlining new features features in iOS 9.3, which released on Monday, March 21. In a nutshell, it alters the warmth of your device’s display to reduce the amount of blue light. Because blue light has been found to keep people awake longer than necessary, Night Shift mode might make it easier for some folks to fall asleep.

In this tutorial, you’re going to learn how to get a better night’s sleep by setting up Night Shift options on your iPhone, iPod touch or iPad. As a bonus, we’ll share a cool tip to override Apple’s limitation, which makes Night Shift unavailable in Low Power Mode.

How Night Shift works

Studies have shown that exposure to bright blue light emitted from a backlit display can affect your circadian rhythms, making it harder to fall asleep.

Night Shift mode on iOS 9.3 uses the time zone information and your device’s Location Services to determine when it’s sunset in your area. Then, it automatically shifts the colors in your display to the warmer end of the spectrum after sunset.

In the morning, Night Shift returns the display to its regular settings. You can also turn Night Shift mode on and off manually or create a custom schedule. Night Shift is not available if your iPhone is in Low Power mode, but there’s a workaround to that which we’ll discuss further below.

But in the meantime, check out my colleague Andrew’s nicely done video walkthrough of Night Shift mode in iOS 9.3.

Keep in mind that Night Shift only works on iOS devices with a 64-bit processor.


Night Shift mode requires iOS 9.3 or later and is compatible with the following iOS devices which run one of Apple’s 64-bit processors:

  • iPhone 5S and iPhone SE
  • iPhone 6 and iPhone 6 Plus
  • iPhone 6s and iPhone 6s Plus
  • iPad Air and iPad Air 2
  • iPad Pro
  • iPad mini 2, iPad mini 3 and iPad mini 4
  • Sixth-generation iPod touch

Night Shift mode is not supported on the following devices:

  • iPhone 5 and iPhone 5c
  • iPhone 4s and earlier
  • Fourth-generation iPad and earlier
  • Original iPad mini
  • Fifth-generation iPod touch and earlier

As mentioned, Low Power Mode may disable Night Shift.

Ways to enable Night Shift mode

You can turn Night Shift mode on and off in several places throughout iOS.

Use the Control Center, Luke!

1) Pull up from the bottom of the screen to bring up Control Center and then tap a brand new Night Shift toggle—the icon looks like crescent moon inside of a sun—to manually enable or disable Night Shift mode on your iPhone, iPod touch or iPad device.

If you set a schedule for Night Shift and then manually enable it via Control Center, a message flashes briefly below the Control Center handle to tell you when Night Shift will turn off, as per your custom schedule.

Tap, tap, tap in Settings

1) Go to Settings → Display & Brightness → Night Shift.

2) Flip the Manually Enable Until Tomorrow toggle to enable or disable Night Shift mode until next morning.

Asking Siri politely will do the trick

Just press and hold the Home button to invoke Siri, and then ask her to “Enable Night Shift” or ”Disable Night Shift”. You can also say “Turn On Night Shift” and so forth.

Siri cannot adjust scheduling options or other Night Shift settings for you.

UPDATE: Due to a server-side fix Apple applied on April 6, 2016, this trick no longer works. Now asking Siri to enable Night Shift while Low Power Mode is activated will yield a warning message offering to disable Low Power Mode before turning on Night Shift.

Set an automatic schedule for Night Shift

Night Shift mode can automatically kick in at predetermined times, if you want. You can choose custom scheduling for Night Shift that suits you best, or have your device keep Night Shift on between sunset and sunrise times in your area.

1) Go to Settings → Display & Brightness → Night Shift and tap Scheduled.

Tip: If you don’t see the Sunrise or Sunset scheduling option, your device has been prevented from determining your time zone automatically. Go to Settings → Privacy → Location Services → System Services and set the Setting Time Zone switch to the ON position.

The Sunrise and Sunset options will now appear in Night Shift settings. If the Sunrise/Sunset options are still unavailable, you may need to restart your device for the changes to take effect.

2) Tap the From/To fields right below to adjust your scheduling options:

  • Sunset to Sunrise: As determined by your device’s time zone and location
  • Custom Schedule: You can customize start and end times for Night Shift

By default, Night Shift is active from sunset to sunrise.

In a true Apple fashion, a Night Shift schedule gradually adjusts the screen colors to gently transition you to your preferred color temperature over the course of a minute.

Adjusting color temperature for Night Shift

You can adjust the warmth or coolness of the colors on your device’s display in Night Shift mode to suit indoor environments that are typically lit with a warmer yellow light.

1) Go to Settings → Display & Brightness → Night Shift.

2) Drag the slider underneath the Color Temperature heading to the left to make the screen colors less warm, which will increase the amount of blue light, or to the right if you prefer a warmer color scheme which will decrease the amount of blue light.

“Warmer settings may affect the appearance of some onscreen motion,” cautions Apple.

As a guidance, your iPhone 6 screen has a color temperature of about 7,100K, or 6,900K for an iPad Air 2, as evidenced on Macmormors’ handy chart above.

How to enable Night Shift when your iPhone is in Low Power Mode

As I mentioned earlier, Low Power Mode and certain display-accessibility settings— such as Invert Colors, Grayscale and Increase Contrast—might disable Night Shift. “Night Shift is disabled in low power mode,” reads a message below the greyed-out Night Shift toggle in Settings when your iPhone is in Low Power Mode.

Sure, you could disable Low Power Mode before turning Night Shift on.

Thankfully, there’s a quicker way to enable Night Shift when an iPhone is in Low Power Mode: just ask Siri to “Enable Night Shift”. This shall turn Night Shift on without exiting Low Power Mode, giving you the best of both worlds.

For those wondering, taking a screenshot when your device is in Night Shift mode produces regular images without a color shift.

Pleasant dreams!

If you have developed a bad habit of reading news, playing games, surfing the web and doing other activities that keep you starring at the screen late at night, right before nap time, Night Shift mode in iOS 9.3 might help you get a better night’s sleep.

  • When it comes time for Nightshift to enable/disable itself via schedule, does it gradually ease in/out as night/day progress or is it simply on or off?

    • It gradually shifts the color over the course over a minute or two, as mentioned in the article. When you enable it manually, it abruptly changes the color scheme.

      • Ohh so it does haha, I must have that. Thanks for letting me know. I believe f.lux does the same thing, doesn’t it?

      • Not sure about that. I’m not jailbroken and don’t use f.lux on my Mac…

      • Mike Chu


      • Ángel Javier Esquivel

        If you manually enable/disable f.lux, it does the fade in/out effect

    • Barcelonian

      It works exactly like f.lux if you have used it before

  • Sailor_V90

    Hopefully with iOS X (10) we’ll get a ‘Dark Mode’ in addition to ‘Night Shift’

  • JulianZH

    Is the sunset to sunrise only for iPhone se? My iPhone 6 only has custom schedule.

    • iDownloadBlob

      The “sunset to sunrise” option is only available when you you turn on location services.

  • Marcus

    Apple should’ve bought out F.lux to get proper implementation into iOS & OS X. F.lux is far superior to Night Shift in my opinion and I’ll be sticking with that.

  • Rumble

    There was an app for this a few years ago in Cydia. I used to use it to deal with retina discoloration issues. Can’t remember the name, darn it. Nice one, Apple, another idea stolen.

    • Tommy

      Flux, and it’s still used

  • Bob

    Feel sorry for F.lux, they were ripped off, apple didn’t allow it on their platform.

  • Xee

    Wish Apple would implement a proper night mode! Not this f.lux poop colour stuff. Turn the white/light stuff black and vice versa so I can use my phone in the dark without burning my retinas.

    • AMB_07

      If you’re talking about inverting colors you can just go ahead and do that via the accessibility options.

    • Donato Bearint

      You can invert the colors, turn the backlight down or just be a normal person and not ask for crazy shit. You sound like the type of person that would like the new pregnancy test app. Download the app and then pee on to your phone like a pregnancy test and then it tells you if you’re pregnant or not you should try that one it works really good I heard.
