Apple has just released iOS 27 beta 3 to developers, marking the second incremental update since the major operating system was unveiled at WWDC earlier this summer. This new beta arrives as Apple continues to refine its next-generation iPhone software, which centers around Siri AI, Apple Intelligence, Liquid Glass design refinements, and a host of quality-of-life enhancements. Developers can now download the build, identified as 24A5380h, through the standard software update mechanism in the Settings app. As with any early beta, Apple emphasizes that this pre-release software should not be installed on a primary device due to expected bugs, battery drain, and compatibility issues.
To install iOS 27 beta 3, open the Settings app, navigate to General, then Software Update, and select iOS 27 Developer Beta under the Beta Updates section. The download size is moderate, and the installation requires a restart. The update is available for iPhones starting from the iPhone 11 and later, including the iPhone SE 2 and newer models. However, some features, particularly those tied to Apple Intelligence and the new Siri AI, require more recent hardware with the necessary neural engine capabilities.
What’s New in iOS 27 Beta 3
This beta brings a variety of changes that both polish the user interface and introduce functional tweaks. One of the most immediately noticeable updates is the Reminders app icon, which now features hollow, colored bullet points instead of the previous solid-colored bullets. This subtle change aligns with the overall Liquid Glass aesthetic that Apple has been promoting across iOS 27, giving the icon a more refined and translucent appearance.
Another significant change involves Apple Intelligence assets. For some users transitioning from beta 2 to beta 3, these assets are being redownloaded, which temporarily resets access to the updated Siri experience. This suggests that Apple has made behind-the-scenes improvements to the machine learning models that power intelligent features, though it may cause a brief interruption for testers who rely on the new Siri capabilities. The Settings app now displays “Optimizing Search and Siri” during indexing, replacing the previous generic text and indicating a more focused background processing task.
Siri itself receives several enhancements in this beta. The Camera app now includes a “Siri Mode” that requires the updated Siri engine to function, hinting at deeper integration between voice commands and photography workflows. Additionally, the voice customization sliders for Pace and Expressivity are working as intended when accessing the new Siri, allowing users to fine-tune how the assistant speaks. These sliders were introduced earlier in the iOS 27 cycle but had been unreliable in previous betas.
Beyond Siri, the update introduces new wallpapers for macOS 27 Golden Gate, specifically the Golden Gate Bridge images and screen savers, though these are not available on iOS directly. On the wearable side, watchOS 27 beta 3 brings Siri AI support and a standalone Siri app, expanding the voice assistant’s presence beyond the iPhone. This cross-platform consistency is a hallmark of Apple’s ecosystem strategy.
Safari also receives attention in beta 3. Upon launching the browser for the first time after the update, users are greeted with a splash screen highlighting four new features: automatically organizing tabs, browsing bookmarks by topic, receiving updates with a “Notify Me” page change tracking feature, and doing more with extensions by creating custom ones. These additions aim to make Safari more proactive and personalized, reducing the manual effort required to manage browsing sessions.
Visual refinements extend to the app icon grid. Specular highlights—the glossy reflections that appear on app icons—are now noticeably softer. This change is particularly evident on clear and tinted icons, which now appear more matte and less glass-like. The adjustment suggests Apple is iterating on the Liquid Glass design language to reduce visual fatigue and improve readability on various wallpapers.
Shortcuts, Apple’s automation app, includes a new option to launch directly into the action view for editing workflows. Previously, users were funneled into a natural language input method, but now they have a choice, giving power users more control over how they build automations. This was spotted by Stephen Robles, a known shortcuts enthusiast.
Finally, the Control Center status bar has been updated to show the cellular network signal and type even when connected to Wi-Fi. This persistent display helps users quickly assess their cellular connectivity without needing to pull down the full status bar, a convenience for those who frequently toggle between Wi-Fi and cellular data.
Broader Context and Testing Notes
iOS 27 beta 3 is part of Apple’s standard summer beta testing cycle. The company is expected to release a public beta later in July, giving non-developers a chance to try the new software. The official public release will follow in September alongside the new iPhone lineup. Until then, developers and early adopters should expect frequent updates as Apple fixes bugs and polishes features.
Some features introduced in earlier betas have been refined or changed in this build. For example, the Apple Intelligence pipeline has proven to be a complex integration, requiring multiple redownloads as the server-side models evolve. This is not unusual for AI-driven features that rely on both on-device processing and cloud updates.
Hardware requirements remain an important consideration. While iOS 27 supports iPhones back to the 2019 iPhone 11, the most advanced features—such as the new Siri AI, advanced photo editing with AI, and real-time language processing—require the A16 Bionic chip or later. This means iPhone 14 Pro and newer models will provide the best experience, while older devices will receive the core operating system improvements but miss out on the headline intelligence features.
Battery life in beta 3 appears to be slightly improved compared to beta 2, though early reports indicate that background activity related to AI asset reindexing can cause temporary drain. As always, performance will vary depending on the device and usage patterns. App compatibility remains a concern; some third-party apps may crash or exhibit unusual behavior until developers update them for the new OS.
Apple has also seeded new betas for iPadOS 27, macOS 27 Golden Gate, watchOS 27, and tvOS 27 alongside this release. Testing across all platforms helps ensure a cohesive experience when devices are used together. For instance, the new wallpapers on macOS and the Siri app on watchOS suggest that Apple is emphasizing seamless continuity between devices.
Developers are encouraged to provide feedback through the Feedback Assistant app, as each beta cycle introduces changes based on tester reports. Crash logs, performance metrics, and feature suggestions help Apple prioritize fixes before the final release.
As the summer progresses, expect additional betas with further refinements. The transition to a more AI-centric operating system is a multi-year effort, and iOS 27 lays the groundwork for future innovations. For now, beta 3 represents a stable step forward, with enough new features to satisfy early testers while still demonstrating the unfinished nature of the software.
If you have discovered any other changes in iOS 27 beta 3, feel free to share them with the community. The feedback loop between Apple and developers is crucial for delivering a polished product to millions of users this fall.
