Apple Unveils iOS 27 Beta 4 with Revolutionary Siri AI Upgrade

Apple has rolled out the fourth iOS 27 beta for developer testing, with the build number 23G71. This new beta iteration replaces the previous third beta and is part of Apple’s beta cycle leading up to a public release later this year. Users enrolled in the Apple Developer Program can access the fourth iOS 27 beta by navigating to Settings > General > Software Update > Beta Updates on their eligible iPhones. The first public beta of iOS 27 was released on July 13, and this latest release is expected to transition to iOS 27 public beta 2 next week, with the final version slated for a fall release.

As is typical with developer betas, users should anticipate encountering bugs, decreased battery life, app compatibility issues, and other imperfections. iOS 27 is heavily focused on artificial intelligence (AI), with Siri AI being the standout feature. This rebuilt assistant is powered by Apple Intelligence and new Apple Foundation Models, offering enhanced conversations, personalized context, expanded knowledge, on-screen awareness, and deeper app integration across the operating system. The visual experience of Siri AI on iPhone has been revamped, with a new Siri mode in the Camera app and improved Camera Control functionality.

Furthermore, iOS 27 introduces AI-powered enhancements for various apps like Photos, Safari, Passwords, Mail, Messages, Phone, Shortcuts, and Home. Some capabilities run on-device, while others leverage Private Cloud Compute. It’s worth noting that not all iOS 27 AI features will be compatible with every iPhone model. The update also includes refinements to the Liquid Glass design introduced in the previous year, including a transparency slider for adjusting the appearance of the system UI.

Performance improvements have been made for app launches, Photos loading, Camera launch in Low Power Mode, AirDrop transfers, and Wi-Fi-to-cellular transitions. Additional changes include Photos keywords and star ratings, customizable slideshows, smoother Camera operation, continuous sending in Messages, Dual Capture in FaceTime, custom EQ for AirPods, new recovery options, easier Apple Pay card switching, and AI-generated wallpaper creation.
