iOS 27 Runs on an iPhone 11. Siri AI Needs a 15 Pro or Newer

Update, 9 November 2026. Apple’s iPhone User Guide now lists Siri AI in English, French, Japanese, Korean, Portuguese and Spanish, where this page said English to start, with the others due in October. The language lines below are corrected. No device list has changed.

Every iPhone from the iPhone 11 and iPhone SE (2nd generation) onward can install iOS 27, including the iPhone 15 and the iPhone 15 Pro Max. Apple Intelligence and the new Siri AI need an iPhone 15 Pro, 15 Pro Max or an iPhone 16 model or later, so the iPhone 15, 15 Plus and iPhone 11 get the update without them. Changing how Siri sounds needs newer still: an iPhone 17 Pro, Air, 18 Pro or Duo.

Every iPhone, model by model

Apple’s iOS 27 page lists 34 iPhone models, counting the iPhone SE (2nd and 3rd generation) and the iPhone Duo, which goes on sale on 23 October. Of those, 15 are on Apple’s Apple Intelligence list.

“Yes” in the Apple Intelligence column is the phone requirement; Siri AI has further conditions, below. Apple’s pages differ on one phone: the iOS 27 page and the Apple Intelligence page list the iPhone Duo, and the iOS 27 version of the iPhone User Guide’s compatibility list did not when we read it.

iPhone 15 Pro and 15 Pro Max: everything but the new voices

The iPhone 15 Pro and 15 Pro Max, both on the A17 Pro chip, are the oldest iPhones on Apple’s Apple Intelligence list. On iOS 27 that brings Siri AI and the Apple Intelligence features in Apple’s release notes: Spatial Reframing, Extend and a stronger Clean Up in Photos; tab grouping and page alerts in Safari; the new Image Playground; and Call Context in the Phone app. What they miss is customising Siri’s voice, which Apple runs on-device on the iPhone Air and iPhone 17 Pro models and later.

iPhone 15 and 15 Plus: iOS 27 without Apple Intelligence

The iPhone 15 and iPhone 15 Plus are on Apple’s iOS 27 list and not on its Apple Intelligence list. So an iPhone 15 owner who installs iOS 27 gets the system changes: the Liquid Glass slider, the redesigned Screen Time and child accounts, Connectivity Assist between Wi-Fi and cellular, and the speed-ups Apple claims. Apple’s “up to 70% faster” figure for new photos loading in Photos was measured on an iPhone 15. It does not get Siri AI, the Photos editing tools or the rest of Apple Intelligence.

The same is true of every iPhone 14, 13, 12 and 11 model, and of the iPhone SE. If Siri AI is the reason you want iOS 27, check your model against the table first.

iPhone 11: the oldest iPhone on the list

All three iPhone 11 models get iOS 27, as do both iPhone SE models Apple still supports. iOS 27 dropped no iPhone: the iOS 26 and iOS 27 versions of Apple’s compatibility list start at the same phones. Apple’s claim that app launches are “up to 30% faster” comes from its own test on an iPhone 11 Pro Max. It also claims AirDrop transfers up to 80% faster, tested on an iPhone 16 Plus. Those are Apple’s figures on Apple’s test phones, not ours.

If an older iPhone feels slow or dies early, its battery is worth checking before you blame the update — how to check battery health on an iPhone, and what the number means. And you are not forced onto iOS 27 yet: on 28 September Apple released iOS 26.7.1 for iPhone 11 and later, the same day as iOS 27.0.1.

Siri AI has conditions beyond the phone

Even on an iPhone that qualifies, Apple lists three more:

• It is a beta. Apple labels Siri AI as beta in iOS 27.
• Six languages. Apple now lists it as “Available in English, French, Japanese, Korean, Portuguese, and Spanish to start”. At release it was English only, with the other five due in October.
• Not in the EU at first. Apple says Siri AI “will not be initially available in the EU” on iPhone.

The server-side features also carry daily usage limits, and Apple says expanded access “will be available for a fee in the future”. We covered what that means in there is no single switch to turn off Apple Intelligence, which also lists every setting if you would rather not use it.

Since release

iOS 27.0.1, released on 28 September, fixes bugs, including Face ID restarts on the iPhone 18 Pro, and changes no device list. Apple’s developer news of 5 October says the iPhone Duo goes on sale on 23 October, and that Xcode 27.1 adds development support for it.

Before you install it

If the update seems to drain your battery in the first days, Apple’s own guidance points to work still finishing in the background, which we set out in battery draining after iOS 27. And if you are buying a phone partly for Siri AI, check the exact model: an iPhone 15 Pro qualifies, and an iPhone 15 or 15 Plus does not.

Macs split the same way on macOS 27, with memory as well as the chip deciding the top tier: which Macs get macOS 27, and which get the new Siri voices. iPads draw their Apple Intelligence line at M1 or the A17 Pro, which leaves the iPad (A16) Apple still sells outside it — which iPads get iPadOS 27. On Apple Watch the split moves to the phone: every watch that runs watchOS 27 is on Apple’s Apple Intelligence list, so the iPhone it is paired with decides Siri AI — which Apple Watches get watchOS 27.

Other Apple features draw their line somewhere else entirely. CarPlay Ultra asks for an iPhone 12 or later on iOS 18.5 or later, which leaves the iPhone 11 family and the iPhone SE (2nd generation) on the iOS 27 list but under the bar — what CarPlay Ultra adds, and which cars have it.

Questions people ask

Does the iPhone 15 Pro Max get iOS 27?

Yes, and it gets Apple Intelligence and Siri AI too. The iPhone 15 Pro and 15 Pro Max are the two oldest iPhones on Apple’s Apple Intelligence list. What they miss is customising how Siri sounds, which Apple limits to the iPhone 17 Pro, Air, 18 Pro and Duo.

Does iOS 27 work on iPhone 15?

Yes. The iPhone 15 and 15 Plus are on Apple’s iOS 27 list, but not on its Apple Intelligence list, so they get the update without Siri AI, the new Photos editing tools or Image Playground. They do get the Liquid Glass slider, the new Screen Time controls and Apple’s speed claims.

Can the iPhone 11 run iOS 27?

Yes. The iPhone 11, 11 Pro and 11 Pro Max are the oldest iPhones Apple lists for iOS 27, beside the iPhone SE (2nd generation). They do not get Apple Intelligence or Siri AI. Apple’s “up to 30% faster” app-launch claim comes from its own test on an iPhone 11 Pro Max.

Which iPhones get Apple Intelligence in iOS 27?

The iPhone 15 Pro, 15 Pro Max, and every iPhone 16 model and later, including the iPhone 16e and 17e: 15 models on Apple’s list, counting the iPhone Duo. Siri AI also needs a supported language (Apple lists English, French, Japanese, Korean, Portuguese and Spanish), and is not initially available in the EU on iPhone.

Did iOS 27 drop any iPhones?

No. Apple’s iPhone User Guide lists for iOS 26 and iOS 27 both start at the iPhone 11 and iPhone SE (2nd generation). Every iPhone that runs iOS 26 can install iOS 27.

Can I stay on iOS 26 instead of updating?

For now Apple is still updating it. On 28 September Apple released iOS 26.7.1 for iPhone 11 and later, the same day as iOS 27.0.1. Apple has not said how long iOS 26 will keep receiving updates.
