Apple restricts Siri's AI features in iOS 27 to newer iPhones

In iOS 27, Apple will give Siri new AI capabilities, but only the latest device models will support them. The company has limited the features to recent hardware because of their high demands on computing power and on dedicated data-processing components.

Which devices will get AI Siri

Owners of the latest iPhone models will be able to use the full set of new AI features for Siri, including advanced context recognition, analysis of conversation history and execution of complex operations in real time. On older models these features are simply unavailable: without enough processor performance, they can't be run.

It comes down to hardware requirements. Running AI features efficiently takes a powerful component base. Apple doesn't want to slow down older devices and has taken a pragmatic path: switch off the new features where they can't run fast enough.

The same applies to iPad, Mac and other Apple devices. The company publishes an official list of compatible devices, but the logic is simple: the newer the model, the more likely it is to get access to everything. Users of three- or four-year-old hardware are left out.

Why newer processors are required

AI features demand serious computing power. Siri has to analyze context, understand complex requests and carry out actions in real time. That takes not just a fast CPU but also dedicated components for machine-learning workloads.

The second issue is data privacy. Apple prefers to process information locally, on the device itself, rather than send it to cloud servers. Local neural-network processing requires dedicated accelerators. The newest A-series processors include them; older models simply lack such components.

What owners of compatible devices get

Those lucky enough to have newer hardware can use the full range of capabilities:

• Contextual understanding of requests and conversation history
• Multi-step operations run directly on the device
• Integration with apps through built-in AI
• Local data processing without sending anything to the cloud
• Better privacy thanks to on-device processing

For owners of incompatible devices, the situation is irritating. They see ads for the new capabilities and read about how much smarter Siri has become, but can't use the features themselves. The device works and the system gets updates, but the door to the future is simply closed.

History repeats itself

This is not the first time Apple has restricted features by hardware generation. With each iOS release, new capabilities demand ever more powerful hardware, and the company simply ends support for older models.

The lesson for users is harsh: if you want new features and want to keep pace with the current version of iOS, it makes sense to replace your device roughly every three to four years. After that, you will gradually be denied new features, even if the device still works fine.

What this means

iOS 27 and AI Siri are another example of Apple's calculated strategy to speed up the upgrade cycle. For most buyers this won't be a disaster: the old Siri will keep working perfectly well. But for those who prefer to keep a device longer, it will be an unpleasant surprise: technological progress will simply pass them by.
