What iOS 27 Is and Why Compatibility Matters
iOS 27 is Apple’s latest iPhone operating system update that brings Liquid Glass design refinements, faster performance, upgraded AI features, and new safety tools, but many headline capabilities are limited to newer devices so knowing the full iOS 27 device list is essential before you update or buy a new iPhone. Apple has released the first developer beta of iOS 27, with a public beta promised next month and a stable release expected later this year. The focus this time is not a total visual overhaul but smoother day‑to‑day use and a major step forward for Siri. However, iOS 27 compatible iPhones fall into two clear tiers: models that get the new Siri AI and Apple Intelligence, and older iPhones that receive the core update but miss those AI extras.
Complete iOS 27 Device List: Which iPhones Are Supported?
Apple has confirmed that iPhone models iOS 27 support are the same as iOS 26, starting from the A13 Bionic chip. That means the iOS 27 compatible iPhones are: iPhone 11, 11 Pro, and 11 Pro Max; the entire iPhone 12, 13, 14, 15, and 16 lineups; the upcoming iPhone 17 family including iPhone Air and the Pro models; plus iPhone SE (2nd generation, 2020) and iPhone SE (3rd generation, 2022). The iPhone XS, XS Max, XR, and all earlier models stay on iOS 26 and will not receive iOS 27. Craig Federighi said on stage that iOS 27 will be “available to more users than any iOS release ever,” highlighting that support now stretches all the way back to iPhone 11. If your device is on this list, you will be able to install iOS 27 when it is released.

Siri AI and Apple Intelligence: A Two‑Tier Experience
The biggest divider in Siri AI iPhone compatibility is hardware. Siri AI and the broader Apple Intelligence suite require an A17 Pro chip or newer with at least 8 GB of RAM. That means full support is limited to iPhone 15 Pro and 15 Pro Max, all iPhone 16 models, and the upcoming iPhone 17, iPhone Air, iPhone 17 Pro, and iPhone 17 Pro Max. Standard iPhone 15 and older models, even though they support iOS 27, do not get Siri AI or Apple Intelligence. The most advanced on‑device AI, such as expressive Siri voices and richer dictation, needs 12 GB of RAM and only runs fully on iPhone Air, iPhone 17 Pro, and iPhone 17 Pro Max. Other supported devices rely more on Apple’s Private Cloud Compute when they access heavier AI tasks, keeping a clear gap between tiers.

Features Every Supported iPhone Gets with iOS 27
Even without Siri AI, older iOS 27 compatible iPhones benefit from a wide set of upgrades. The refined Liquid Glass design carries over from iOS 26, and a new slider in Settings lets you personalise how strong the effect appears, from ultra‑clear to heavily tinted, with sharper app icons across the board. Apple also promises meaningful speed gains: apps can launch up to 30% faster, photos can load up to 70% faster after being taken, and AirDrop transfers can be up to 80% faster. Core apps such as Photos, Mail, and Spotlight search have been rebuilt for quicker results. New child safety and parental controls add age‑aware protections, "Ask to Browse" web permissions, tighter time limits, and Communication Safety to block violent or graphic imagery for young users on any supported iPhone.
Should You Upgrade Your iPhone for iOS 27?
If you already own an iPhone 11 or newer, you will be able to install iOS 27 and enjoy the Liquid Glass refinements, performance improvements, and safety upgrades. However, your experience depends on your hardware. iPhone 11 through iPhone 14, iPhone 15 and 15 Plus, and both iPhone SE models will miss the flagship AI features, including Siri AI, Apple Intelligence, and the most advanced on‑device processing. For many people, the speed gains and updated apps may be enough to stay put. Power users who care about conversational Siri, context‑aware actions across apps, and AI‑driven photo tools may want to move to at least an iPhone 15 Pro or wait for the iPhone 17 series.
