Turn your iPhone into an alarm clock.

See the time, temperature, and battery level clearly on your phone's display.

Use nighttime mode to maintain sleep with a dim red-tinted screen.

Your iPhone can be used at all times of the day, even when you aren't necessarily planning to. Obviously, you likely spend a lot of time during the day texting, scrolling, looking things up, calling, and creating content, but there's something useful you can do with it at night you might not be aware of.

Many people use their iPhone as an alarm clock at night by resting it on top of their nightstand, offering quick access to a wide variety of information, including the current temperature, missed calls, the battery level, and more. This is where StandBy Mode comes into play. Standby Mode is a special mode you can set your iPhone 13 and above (with iOS 17) to while you're charging it (it works best on iPhones with an always-on display).

The feature doesn't need to be used at night, but this is likely when most people will find it useful. For Standby Mode to work, your iPhone needs to be positioned in landscape orientation. With all that in mind, below is everything you can do with your iPhone in StandBy Mode.

Using your iPhone in StandBy mode offers a clear clearer view of your iPhone. As mentioned above, if you're laying it down on your nightstand, you likely have to crane your neck, shuffle your body around, and hoist it up -- and still probably pick up the phone to see what time it is. But with StandBy Mode, the phone will clearly display the time, and you can even choose the font and what the display looks like.
