Apple released iOS 27 beta 5 yesterday, bringing a wave of refinements to the iPhone experience. Among the many changes, the update tweaks the Liquid Glass transparency slider, allowing users to make the interface even more transparent than earlier betas. The enhancement is subtle but meaningful for those who appreciate a cleaner, more glass-like aesthetic.
When iOS 27 was first unveiled at WWDC, Apple described Liquid Glass as a fundamental redesign of the iPhone interface. It replaces the flat, solid surfaces of earlier iOS versions with translucent materials that dynamically adapt to the content behind them. The design language affects app icons, Control Center, lock screen widgets, and system menus, creating a cohesive visual identity across the entire operating system.
Liquid Glass slider in iOS 27 now enables even more transparency
iOS 27 introduces a dedicated Liquid Glass slider in the Settings app. Located under Settings > Appearance > Liquid Glass, the slider lets users choose their preferred level of transparency. Options range from highly transparent to heavily tinted, with a continuum in between. This level of control is new to iOS and gives users unprecedented say in how their device looks.
In beta 5, Apple adjusted the slider's upper limit. The most transparent setting, sometimes referred to as "Ultra Clear," now pushes transparency further than it did in previous betas. That means users who want the most see-through interface possible can now achieve it. A comparison shared on social media demonstrates the difference, showing how the home screen wallpaper and app icons appear with the updated Ultra Clear setting versus the earlier maximum. It's not a dramatic overhaul, but the change is noticeable in everyday use.
A closer look at the new transparency options
The Liquid Glass slider works by controlling the opacity and tint of materials used throughout iOS 27. At the most transparent end, UI elements like the dock, folders, and notification panels blend almost seamlessly with the wallpaper. Text and icons remain readable because Apple applies subtle shadows and contrast adjustments. At the most tinted end, the interface takes on a more saturated, colorful appearance, which may appeal to users who prefer stronger visual separation.
Beta 5's update to the Ultra Clear setting is particularly significant for users who customize their devices with vibrant wallpapers or complex imagery. With greater transparency, those images become more visible through system surfaces, enhancing the sense of depth and immersion. The change also aligns with a broader trend in modern UI design toward glassmorphism, where translucent layers create a sense of physical depth.
Additional improvements in iOS 27 beta 5
Beyond the Liquid Glass tweak, iOS 27 beta 5 includes redesigned app icons. Apple has refined the shapes, colors, and shading of first-party icons to better suit the new design language. The icons feature more subtle gradients and an almost tactile quality, making them appear as if they are etched into the glass behind them.
The beta also introduces new Siri AI voice options. These additions give users more choices for Siri's voice, leveraging Apple's on-device machine learning to produce more natural and expressive speech. While the voice options have been in development for several cycles, beta 5 appears to refine the audio quality and responsiveness.
Other improvements likely include bug fixes, performance enhancements, and battery life optimizations, though Apple's release notes are typically sparse on specifics. As with every beta, developers and testers are encouraged to report issues, and Apple is expected to make further adjustments before the public launch.
The evolution of Liquid Glass design
Liquid Glass represents a significant departure from the flat design that Apple adopted with iOS 7. That design vocabulary, which emphasized minimalism and thin fonts, dominated for more than a decade. But as hardware capabilities improved, Apple began reintroducing depth and texture in subtle ways. The introduction of Liquid Glass goes further, creating an interface that feels both modern and organic.
The design takes inspiration from physical glass, including its ability to reflect, refract, and transmit light. iOS 27 simulates these properties digitally, with materials that change in response to the content scrolling beneath them. This creates a dynamic, living interface that adapts to the way users interact with their devices.
The customization potential of the Liquid Glass slider is a logical extension of Apple's focus on user choice. While the company has historically maintained strict control over visual consistency, recent versions of iOS have introduced more options, such as dark mode and tinted app icons. The slider represents a middle ground, allowing personalization without fragmenting the overall aesthetic.
How to get the most from the transparency slider
To access the new transparency controls, install iOS 27 beta 5 on a compatible device. After updating, navigate to Settings > Appearance > Liquid Glass. Drag the slider to the left for maximum transparency or to the right for more tint. The system updates live, so you can see the effect immediately on the background and UI elements.
It's worth experimenting with different content. For example, a busy wallpaper with fine details may look best with a moderate level of transparency, while a simple gradient might pair well with the most transparent setting. Apple has also integrated the slider with other appearance settings, so you can combine it with light or dark mode, as well as color tinting.
Considerations for readability and accessibility
While greater transparency is visually appealing, it can affect readability. Users who struggle with low-contrast text may prefer to reduce transparency or enable the Reduce Transparency accessibility setting. iOS 27 still includes these accessibility options, which override the Liquid Glass slider to prioritize legibility. Apple has emphasized that the design is flexible enough to accommodate a range of visual needs, and beta testers have reported that even at the most transparent setting, system text remains legible in most cases.
Battery life is another consideration. Although Liquid Glass is rendered using the GPU, the performance impact is minimal on modern iPhones. However, some users have noticed slightly increased resource usage with extremely transparent backgrounds, especially when using complex wallpapers. Apple will likely optimize this further in the final release.
What to expect from iOS 27's full release
iOS 27 is expected to launch to the public next month, likely alongside new iPhone hardware. The update will be available as a free download for compatible devices. Apple typically seeds a release candidate in early September, followed by the official rollout a week or so later. Beta 5 is a strong indicator that the core features are feature-complete, and remaining betas will likely focus on stability and performance.
The new Liquid Glass transparency options are part of a broader effort to unify the Apple ecosystem. Similar design principles are expected to appear in iPadOS 27, which was announced at the same event. Apple enthusiasts see this as a foundational step toward a more consistent cross-platform experience, though the company has not confirmed specific future features.
For now, users who appreciate the new look can enjoy beta 5's enhanced transparency. The change may seem minor on its own, but it reflects Apple's willingness to refine and expand the design based on feedback and technical capability. As the public launch approaches, more users will get to experience the full range of Liquid Glass customization, and the conversation about the ideal level of transparency will likely grow. Whether you prefer a clear view or a rich, tinted look, iOS 27 aims to give you control over your device's appearance like never before.
