There Are New Settings for StandBy Mode
StandBy Mode is a cool new feature in iOS 17 that lets you use your iPhone as a clock or digital picture frame when you’re going to bed or sitting in the office. While this feature already works great, Apple is making it better by letting you customize how you want to use it.
For instance, you’ll now have the option to turn off the display after a certain amount of time. You can turn off the screen after 20 seconds, so you save some battery and don’t get distracted by it. And, of course, you’ll also have the option to leave the screen on all the time.
Unfortunately, these new settings are only available for iPhones with an Always-On display. So, unless you have an iPhone 14 Pro, iPhone 14 Pro Max, iPhone 15 Pro, or iPhone 15 Pro Max, you won’t see them. Other iPhone models can still use StandBy, but the display will always turn off after 20 seconds.
