This can be particularly useful for reducing glare quickly when you need it.Ī more conventional way to switch to dark mode on iOS is to go to settings. You can even add a dark mode dedicated button to the control centre by going to settings > control centre > customise controls. Press and hold on the brightness slider and tap ‘Appearance’ on the bottom left to switch between light and dark modes as you please. To enable dark mode on iOS, the easiest way is to swipe from the home screen to get to the control centre, down from the top right on an iPhone X or newer, or up from the bottom on an iPhone 8 or older.
