How to Enable Night Shift on Your iPhone

Apple says that your iPhone’s display provides a “brilliant viewing experience,” which means it’s very bright. That’s great during the day, when you probably need the display to be as bright as possible, but what about at night? Recent research suggests that starting at screens after sunset can disrupt your sleep cycles.

What is Night Shift, and what does it do on your iPhone? The iPhone’s Night Shift feature customizes your display’s lighting by changing the color of your screen, so you’re not as wired when you try to go to sleep. At night, Night Shift changes the brilliant “blue light” brightness that mimics sunlight to one that closely resembles the warm “red light” brightness of an incandescent light bulb or candle.

Here’s how to enable the Night Shift feature on your iPhone:

  1. From your iPhone’s home screen, tap Settings.

  2. Tap Display & Brightness.

  4. Move the Scheduled switch to the on position to enable Night Shift.

  5. Tap Schedule, and then select Sunset to Sunrise. This setting will allow Night Shift to automatically change your iPhone’s brightness based on the time of day.

  6. You can optionally use the Color Temperature slider to manually adjust the amount of blue light and red light brightness.

Night Shift is now enabled on your iPhone! There’s nothing else to configure. From now on, your iPhone’s display will automatically shift to “red light” brightness after the sun sets.
