iOS 16 adds a customizable Lock Screen that lets iPhone users personalize the display with widgets, font choices, and wallpaper options. To create a new Lock Screen, users long‑press the current screen, tap the blue plus icon, select a wallpaper from available categories, and add widgets by tapping or dragging them into the bottom area. Up to four small widgets, two small and one medium, or two medium widgets can be placed in the bottom section, and one additional widget may appear in the top day/date area. Users can customize the time’s font and color by tapping the time display and swiping to reveal more color choices. Widgets provide live information but are not interactive; tapping a widget opens the corresponding app. Multiple Lock Screens can be created at any time, and users switch between them by long‑pressing the screen and swiping to the desired design. Custom Lock Screens are removed by swiping up on the screen and tapping the trash icon. Weather and Astronomy wallpapers use location data updated every 15 minutes, which may impact battery life. Apple continues to expand personalization features in iOS 16.
