Apple is set to unveil iOS 27 with an all-new Siri app and more next week, but there are some compatibility details to know about.

According to Instant Digital, a known Apple leaker on the Chinese social media platform Weibo, iOS 27 will be compatible with the iPhone 12 series and newer. However, given the more personalized version of Siri will be powered by Apple Intelligence, the revamped Siri is expected to be limited to the iPhone 15 Pro and newer.

If this rumor is accurate, iOS 27 will drop support for the following iPhone models:

• iPhone 11
• iPhone 11 Pro
• iPhone 11 Pro Max
• iPhone SE (2nd generation)

However, these devices will continue to receive iOS 26 security updates for at least a few years.

iOS 27 will be compatible with the following iPhone models, according to the leaker:

• iPhone 17e
• iPhone 17
• iPhone 17 Pro
• iPhone 17 Pro Max
• iPhone Air
• iPhone 16e

Apple will unveil iOS 27 during its WWDC 2026 keynote this Monday, June 8, and the first developer beta should be released later that day. A public beta typically follows in July, ahead of a final release to all users in September.

iOS 27 been likened to Mac OS X Snow Leopard, in the sense that Apple is reportedly focused on bug fixes and stability improvements. There will still be some new features, though, including the dedicated Siri app with ChatGPT-like chatbot functionality and Apple Intelligence enhancements across other Apple apps.

Instant Digital has accurately leaked Apple information before, such as the yellow color for the iPhone 14 and iPhone 14 Plus, and the Apple Watch Ultra 2's Titanium Milanese Loop. However, the account does not have a perfect track record.
