Apple is one week away from WWDC 2026, and the pre-keynote leaks are coming in fast. The latest one is worth paying attention to if you are sitting on an older iPhone, because iOS 27 compatibility may be narrower than some were hoping.
According to Instant Digital, a Chinese leaker on Weibo with a reasonable track record on Apple details, iOS 27 will require an iPhone 12 or newer. That means four devices are getting cut off entirely: the iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, and the second-generation iPhone SE. If you are on any of those, iOS 26 is your final chapter, though Apple is expected to keep security updates coming for at least a few more years, so you are not being left completely exposed overnight.
The drop itself is not surprising. The iPhone 11 launched in 2019, which means these devices would have had six full years of iOS support by the time iOS 27 ships in September. That is a generous run by any measure, and broadly in line with what Apple has historically offered.
The Siri Situation Is the More Interesting Story
Making the compatibility cut does not mean you get everything iOS 27 has to offer. The headline feature is a completely rebuilt Siri, essentially a ChatGPT-style conversational assistant baked directly into the OS with its own dedicated app. That version of Siri runs on Apple Intelligence, which means it is limited to the iPhone 15 Pro and newer. If you are on an iPhone 12 through iPhone 15, you get iOS 27 but you do not get the new Siri. That is a meaningful distinction that the headline compatibility list does not make obvious.
So in practice there are three tiers of experience here. iPhone 11 and older: no iOS 27 at all. iPhone 12 through iPhone 15 standard: iOS 27 with most features but without the revamped Siri. iPhone 15 Pro and newer: the full package.
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)
These devices will not be left completely in the cold, however. Apple is expected to continue pushing iOS 26 security updates to them for at least a few years, meaning they stay protected even without access to the new release.
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
- iPhone 16
- iPhone 16 Plus
- iPhone 16 Pro
- iPhone 16 Pro Max
- iPhone 15
- iPhone 15 Plus
- iPhone 15 Pro
- iPhone 15 Pro Max
- iPhone 14
- iPhone 14 Plus
- iPhone 14 Pro
- iPhone 14 Pro Max
- iPhone 13
- iPhone 13 mini
- iPhone 13 Pro
- iPhone 13 Pro Max
- iPhone 12
- iPhone 12 mini
- iPhone 12 Pro
- iPhone 12 Pro Max
- iPhone SE (3rd generation)
One caveat worth noting: being on this list does not guarantee the full iOS 27 experience. The rebuilt Siri app runs on Apple Intelligence and is expected to be limited to the iPhone 15 Pro and newer, so a significant portion of supported devices will get the update without access to its headline feature.
What iOS 27 Actually Is
It is worth tempering expectations slightly for everyone, because iOS 27 has been widely described as Apple’s Snow Leopard moment. If you remember Mac OS X Snow Leopard, Apple spent an entire release cycle focused almost entirely on stability, performance, and under-the-hood improvements rather than splashy new features. iOS 27 is reportedly following the same philosophy, with bug fixes and polish taking priority over a long feature list.
That is not a criticism. After a few years of aggressive feature additions, a consolidation release is arguably what the platform needs. The new Siri app with its chatbot functionality is the obvious centrepiece, alongside Apple Intelligence improvements across the broader app ecosystem, but do not go into WWDC on Monday expecting a radical visual overhaul or a dozen new headline features.
The Leaker’s Track Record
Instant Digital has called things correctly before, including the yellow colorway for the iPhone 14 lineup and the Apple Watch Ultra 2’s Titanium Milanese Loop. That said, the account does not have a perfect record, so treat the compatibility list as a strong indication rather than confirmed fact. Apple will make everything official during the WWDC keynote on Monday June 8, with the first developer beta expected the same day and a public beta following in July ahead of a September release.
