How to Use iOS 17 StandBy Mode in iPhone Sleep Mode & Other Focus Modes

StandBy mode is a feature in iOS 17 and later that is sometimes called nightstand mode. It will turn off automatically unless you have an iPhone with an Always-On display. Even if your Always-On display is toggled on, using Focus modes such as Sleep Focus will turn the StandBy mode screen off automatically. However, as long as you have Always-On display toggled on, you can adjust a single StandBy setting to make sure your screen never turns off.
