How to use Night Shift on your iPhone
IOS’s Night Shift feature allows you to filter out blue light and adjust the color warmth on your screen. It automatically adjusts the colors of your screen at sunset to your location, using geolocation and your phone’s clock to determine it. When it’s morning, it will revert your display to its usual settings. You can activate Night Shift by opening Control center and pressing Brightness adjustment. Then tap on the symbol that looks like a small sun. Otherwise go to Settings> Display and brightness> Night Shift.
We recommend that you adjust the Night Shift settings here by toggling Schedule and enter the hours for it to turn on and off automatically. Ours is on from 10 p.m. to 7 a.m. If you don’t program a time, it will automatically turn on at sunset and turn off at sunrise. You can also activate it manually overnight.
