StandBy is a new feature for iPhones and it's excellent. To get access to StandBy, you need to have a compatible iPhone running on iOS 17 and your iPhone needs to be charging and in a landscape orientation. The feature then turns your iPhone's display into a small smart display, similar to the Google Nest Hub and Amazon Echo Show, offering glanceable information like the date, time and useful widgets. It will also show you your photos if you select that screen.
