Apple has released the public beta for iOS 27, and the compatibility list brings an unexpected twist: 29 iPhone models can run the new software, including some older devices that many thought would be dropped.
What Is the iOS 27 Public Beta?
A public beta is an early, unfinished version of Apple’s software that regular users can install. It’s a chance to try out new features before the official release, but remember, bugs are part of the experience. Typically, Apple rolls out the official version of a major iOS update in September, coinciding with new iPhone hardware.
iOS 27 is shaping up to be one of the most significant software updates from Apple in years. The standout feature is a revamped Siri that utilizes on-device AI capabilities. This means your iPhone can handle smarter requests without sending your data to a remote server. Apple also promises performance upgrades across all supported devices and a new visual design called Liquid Glass, which gives the interface a more translucent, layered appearance.
According to 9to5Mac, this public beta offers users an early look at Apple’s most significant software update of the year, with Siri AI and speed improvements being major highlights.
Is Your iPhone on the List?
The biggest surprise from WWDC 2026 was the extensive reach of the iOS 27 compatibility list. Apple supports 29 iPhone models in total. Generally, if your iPhone has an A12 Bionic chip (which debuted with the iPhone XS in 2018) or a newer one, you can install the base iOS 27 update. Some AI-specific features will need newer chips and will only work on the latest models.
Practically speaking, if you own an iPhone XR, XS, or XS Max from 2018, you’re good to go with iOS 27. However, if you have an iPhone X or an older model, you won’t be able to install it.
While 29 iPhones support iOS 27, the complete Siri AI features will likely need at least an iPhone 15 Pro or later, based on Apple’s chip requirements for on-device AI processing.

Should You Install It Right Now?
The short answer? Probably not on your main device. Public betas are more stable than developer betas (the version released only to app developers earlier in the cycle), but they still come with risks. Apps might crash, battery life could suffer, and some features may not function as expected.
If you have an older iPhone lying around, that’s the perfect test device. If your daily phone is your only iPhone, it’s wiser to wait for the official release this fall. 9to5Mac’s guide on whether to install the public beta goes into the risk-benefit analysis in detail.
To install the beta, enroll your device at beta.apple.com, then download the profile through your iPhone’s Settings app.
| Stat | Detail |
|---|---|
| Compatible iPhones | 29 models |
| Oldest supported iPhone | iPhone XR / XS / XS Max (2018) |
| Chip required for base iOS 27 | A12 Bionic or newer |
| Developer beta rounds before public beta | 3 |
| Expected official release | Fall 2026 (alongside new iPhone hardware) |
| Key new features | Siri AI, Liquid Glass design, performance upgrades |
What This Means
For most iPhone users, the compatibility news is positive. Apple keeping devices from 2018 on the supported list means millions who haven’t upgraded in years will still receive iOS 27, although some of the more advanced AI features will be unavailable to them. If you want the complete Siri AI experience, newer hardware is clearly the way to go.
If you own an iPhone 11 or 12, this update could significantly extend your device’s lifespan. Apple’s promised performance improvements aren’t just marketing hype. Major iOS releases typically include optimization that can make older hardware feel faster, though results can vary by device.
The Liquid Glass redesign is a bit of a wildcard. It’s a major visual shift for an interface that millions rely on daily. Some users will love it, while others might take time to adjust. The beta is actually helpful here: it lets you try it out before the change becomes permanent in September.
Community Reactions
“Been on the beta since day one of developer builds, honestly the performance bump on my iPhone 13 is noticeable. Apps open faster and it just feels snappier. Liquid Glass takes getting used to but I’m into it.”
“Dropped it on my iPhone XS and it runs fine so far. Wild that Apple still supports a 2018 phone for this. Just don’t expect any of the AI stuff to work.”
What To Watch
- Beta 2 release: Apple usually drops a second public beta within two to three weeks of the first. This build typically addresses the most common crashes and bugs reported by early testers.
- September 2026: The official iOS 27 release is expected during Apple’s annual iPhone event, where new hardware is usually unveiled.
- AI feature availability: Keep an eye out for Apple to clarify which Siri AI features work on which chip generations. The cutoff between full and partial AI support hasn’t been fully explained yet.
- Liquid Glass reception: Developer and user feedback on the visual redesign is already influencing how Apple fine-tunes the interface before the final release. If there’s strong backlash, expect adjustments before September.
