New AI photo tools include Extend (frame expansion) and Spatial Reframe for Vision Pro. Long-awaited quality-of-life fixes arrive: separate alarm volume, smoother Wi-Fi-to-cellular handoff, CarPlay audio scrubbing, custom AirPods EQ, and a liquid glass opacity slider. A new CPU scheduler reportedly delivers meaningful performance gains, especially on older devices like the iPhone 11. The beta is stable enough to explore but best tested on a spare device rather than a primary phone. ## Content Apple released the iOS 27 public beta this week, and it's generating more genuine excitement than most beta cycles. Here's what's actually in it and whether you should bother installing it. ## The new Siri The headline feature is a completely rebuilt Siri. Apple rebuilt it using Foundation Models developed in collaboration with Google's Gemini via distillation, running on-device with Private Cloud Compute handling anything that needs to leave the phone. It now has deep OS integration, a standalone app, and Spotlight integration. More practically: it can actually access your emails, photos, and messages to answer questions about your own life, which the old Siri famously couldn't do. Early developer beta testing showed it handles tasks noticeably better than before, with occasional errors. It's not perfect, but it's a meaningful step up. ## Photo editing Two new AI photo tools stand out. **Extend** lets you expand the frame of a photo beyond its original edges, generating plausible content to fill the gap. **Spatial Reframe** is aimed at spatial photos and video, letting you reframe the composition after the fact. Both are the kind of features that sound gimmicky until you actually need them. ## Liquid glass opacity Apple added a transparency slider for the liquid glass UI effect introduced this cycle. If the frosted glass aesthetic isn't your thing, you can dial it back. Small thing, but people have been asking for it. ## Long-overdue fixes A few things that should have shipped years ago are finally here: - Separate volume control for alarms (independent from ringer volume) - Better Wi-Fi to cellular handoff when leaving the house - Media scrubbing in CarPlay - Custom EQ for AirPods None of these are glamorous, but the alarm volume fix alone will make a lot of people happy. ## Performance This might be the most underreported part of the update. Apple reworked the CPU scheduler, and the result is a noticeably snappier feel across the board. Older iPhones going back to the iPhone 11 reportedly benefit the most. If your phone has felt sluggish lately, this is worth paying attention to. One developer put it bluntly: "iOS 27 beta is the most stable iOS right now." That's a low bar in some ways, but it does suggest Apple focused on fundamentals this cycle rather than piling on new features. ## Should you install it? The public beta is stable enough that Apple felt comfortable releasing it to everyday users, and early reports back that up. That said, "stable for a beta" still means occasional crashes and rough edges. The sensible approach: if you have an older spare iPhone sitting in a drawer, put it on there. If your daily driver is your only phone, wait for the full release. The improvements are real, but none of them are urgent enough to risk your primary device on beta software. ## Questions this post answers ### What's new in the iOS 27 public beta? The iOS 27 public beta introduces a rebuilt Siri using on-device Foundation Models developed with Google Gemini via distillation, with Private Cloud Compute handling offloaded tasks. It adds two AI photo tools, Extend and Spatial Reframe, an opacity slider for the liquid glass UI, fixes like separate alarm volume control, better Wi-Fi to cellular handoff, CarPlay media scrubbing, and custom AirPods EQ, plus a reworked CPU scheduler for better performance. _Developers tracking Apple's platform shifts can follow iOS beta changes as they land on daily.dev._ ### Does the iOS 27 CPU scheduler update improve performance on older iPhones? Yes, Apple reworked the CPU scheduler in iOS 27, resulting in a noticeably snappier feel across devices. Older iPhones going back to the iPhone 11 reportedly benefit the most, making this update especially relevant for anyone with an aging device that has felt sluggish. _Anyone deciding whether to update an older iPhone can weigh performance changes like this via daily.dev._ ### Is it safe to install the iOS 27 public beta on my main iPhone? It is not recommended for a primary device. The public beta is described as unusually stable for a beta release, with one developer calling it the most stable iOS beta available, but it still carries occasional crashes and rough edges.
