Apple unveiled iOS 27 at WWDC this week, and while the headline-grabbing Siri overhaul has received the most attention, the Lock Screen has picked up several refinements that you may have missed.
Some are brand-new additions, while others are tweaks to features Apple introduced in iOS 26, but together they give you more control over how your Lock Screen looks and behaves.
Here are five to try if you plan to install the public beta next month, or when iOS 27 becomes generally available in the fall.
Extend Your Wallpaper
A new wallpaper extension feature in iOS 27 uses Apple Intelligence to automatically expand a photo beyond its original boundaries so it fills the entire Lock Screen more naturally. If a photo is cropped too tightly, doesn't match your iPhone's aspect ratio, or it leaves empty space when positioned on the Lock Screen, iOS 27 can generate additional image content around the edges with the "Extend" option. It will analyze the existing image and create matching background details that blend with the original photo, so there's no need for aggressive cropping. The Extend option can also be found in the Photos app.
Make the Clock Tiny
A new compact clock mode is available as a new Lock Screen layout option in iOS 27. Found in the top-right corner of the Font & Color panel, the option moves the time from its traditional large, centered position to a much smaller format alongside the date and widgets at the top of the screen. It's a nice option to have if you like a cleaner Lock Screen look that shows off your wallpaper more fully, and it's the complete opposite effect introduced in iOS 26 that stretches the clock down the screen.
Generate Wallpapers With AI
iOS 27 also expands Image Playground with support for AI-generated Lock Screen wallpapers. You can create custom backgrounds using text descriptions, and the app will generate entirely new images tailored to your preferred style, subject matter, or aesthetic, allowing you to set it directly as your Lock Screen wallpaper.
Change Liquid Glass Opacity
In iOS 27, Apple added a full Liquid Glass slider under Settings ➝ Appearance ➝ Liquid Glass. It changes the translucency of Liquid Glass elements, and you can choose a clear version of Liquid Glass that allows some of the background to show through, select a more opaque, tinted version that improves the legibility of text, or choose something in between. Granted, it's more of a system-wide customization feature than a Lock Screen-exclusive feature, but it directly impacts the look of your clock setup, buttons, widgets, and notifications.
New Siri Interface
To go with Apple's tentpole "Siri AI" chatbot-style overhaul, iOS 27 introduces a redesigned Siri experience. Instead of the glowing light effect that previously traced the edges of the display, a swirling Siri orb now expands and animates within the Dynamic Island. Siri requests and responses are also now presented in a more compact interface surrounding the Dynamic Island, so interactions should feel more focused rather than completely taking over your Lock Screen.
