iOS 27 Supported iPhones: Full Compatibility List

Short answer: which iPhones support iOS 27?

The stable cutoff is iPhone 11 or later, with a separate exception for iPhone SE (2nd generation) and iPhone SE (3rd generation). Apple lists every iPhone 11, 12, 13, 14, 15, 16, and 17 family shown below, together with current iPhone 18 Pro models. The exact newest-model names can vary across Apple's regional pages, so use Settings → General → About to identify the device you actually own.

If your phone is an iPhone XR, XS, XS Max, X, 8, 8 Plus, or an older model, it is absent from Apple's iOS 27 compatibility guide. Do not treat a third-party download profile or an available beta file as evidence that the model is supported.

Supported and unsupported boundary at a glance

The easiest mistake is to read “iPhone 11 and later” as a release-date rule that automatically includes every similarly dated name. Use the exact model name instead. The iPhone SE (2nd generation) is supported even though it uses a Home button, while the iPhone XR and XS family are not supported even though they run earlier iOS releases.

Does iPhone 11, XR, XS, or SE support iOS 27?

These models are often grouped into one question, but they do not have the same result. Apple lists every iPhone 11 model as compatible with iOS 27. It does not list iPhone XR, iPhone XS, or iPhone XS Max. Use the complete model name instead of estimating from appearance or purchase year.

The iPhone SE answer also depends on generation. Apple lists the 2nd- and 3rd-generation models; the 1st-generation iPhone SE is absent. If Settings shows only a model number, identify the generation first and then compare it with Apple's list.

How to identify your exact iPhone model

Open Settings → General → About and read Model Name. This is more reliable than identifying the phone from screen size, camera count, case shape, or a seller's listing. If Model Name is unavailable, tap Model Number to reveal the A-number and compare it with Apple's Identify your iPhone model article.

Also record the current iOS version and available storage. A compatible model can still fail to show or install iOS 27 because of storage, network, battery, update-server, or management-policy conditions; that does not change the compatibility list.

1. Open Settings on the iPhone.
2. Tap General, then About.
3. Read Model Name and compare the complete name with the table above.
4. Return to General → Software Update to see the version Apple currently offers to that device.

Why Apple pages can show slightly different newest-model names

Apple's global iOS 27 product page currently includes iPhone Duo in its compatibility section, while the English iPhone User Guide lists iPhone 18 Pro and iPhone 18 Pro Max but does not list iPhone Duo. Some other regional product pages also omit models that appear on the global page. This is a first-party page difference, not a reason to merge names or invent a standard iPhone 18 entry.

For established models from iPhone 11 through iPhone 17 and the SE generations, the support guide provides a consistent reference. For a newly released or region-specific model, confirm the exact Model Name and use Software Update on the device; Apple can revise regional pages after publication.

Being compatible does not unlock every iOS 27 feature

An iPhone 11 can install iOS 27, but that does not make it an Apple Intelligence-capable phone. Apple's current Siri AI requirements start with iPhone 15 Pro models and iPhone 16 models or later, including iPhone Air. Device language, Siri language, Apple Account region, and local availability also affect whether Siri AI appears.

Apple says Siri AI is currently available in beta in English and is not currently available on iPhone for residents of the European Union or for Apple Accounts in mainland China. Other iOS 27 features can have their own hardware, language, carrier, and region requirements. Check the feature-availability page for the feature you care about before upgrading for that feature alone.

Prepare before installing iOS 27

Apple's update guide says your data and settings remain unchanged during a normal update, but it still directs users to set up automatic backup or make a manual backup first. Confirm that the latest iCloud or computer backup completed, keep enough free storage, connect to reliable Wi-Fi, and leave the phone connected to power during installation.

Apple's security releases page records iOS 27 as released on September 14, 2026 for iPhone 11 and later. It also notes that an installed iOS update cannot generally be downgraded to the previous version, so compatibility alone is not a reason to update a critical device without a backup and app-compatibility check.

1. Verify the latest backup date rather than only checking that backup is enabled.
2. Check Settings → General → iPhone Storage and leave working space for the download and installation.
3. Update essential banking, authentication, work, and accessibility apps first.
4. Install from Settings → General → Software Update, not from an unofficial profile or download site.

What if a supported iPhone does not show iOS 27?

First confirm the exact model and current iOS version. Then restart the phone, reconnect to a reliable Wi-Fi network, connect power, and check available storage. Remove a partially downloaded update only through Settings → General → iPhone Storage, then let Software Update download it again.

A work or school device can be delayed by management policy, and Apple can stage availability by region or device condition. Do not erase the phone merely because the update is missing. If an update still fails, use Apple's supported update path from Finder on a Mac or Apple Devices on Windows after verifying a current backup.
