Apple is set to launch WatchOS 27, featuring a redesigned AI-powered Siri, but the update will only be available for newer Apple Watch models, leaving older devices behind. The new Siri. Now dubbed Siri AI. Is designed to understand natural language more effectively, allowing users to have more fluid and contextual conversations, but this upgrade aims to bring Apple’s voice assistant in line with AI-powered alternatives like Google’s Gemini and ChatGPT.

Revamped Siri and AI Integration

The new Siri AI will be integrated into Apple’s environment, including iOS 27, iPadOS 27, macOS 27, and WatchOS 27 — According to Apple, this AI will offer better contextual awareness and the ability to pull information from other apps in real time. This means users can ask complex questions without having to rephrase or repeat details — For example, after asking about a trip, users can ask follow-up questions without restating the entire context.

According to Applesfera. This update has been a long time coming; While Apple announced plans for an AI-enhanced Siri two years ago, the feature was delayed until now. The company has also integrated Google’s Gemini models to power Siri AI, marking a significant shift in Apple’s AI strategy.

Compatibility Concerns for Apple Watch Users

However, not all Apple Watch owners will be able to take advantage of this update. WatchOS 27 will only support the Series 9 and newer models, as well as the Ultra 2 and newer and the SE 3. This means that devices like the Series 6, 7, 8, original Ultra, and the second-generation SE will no longer receive updates. According to CNET, this is a much more aggressive cutoff than usual, potentially leaving many current Apple Watch owners at the end of the update road.

Apple’s software engineering vice president, Craig Federighi, emphasized the importance of privacy in the new AI integration. He stated that Apple’s mission has always been to make advanced technology accessible through intuitive and useful products, and that the new AI must be built around user needs while protecting personal data. These features will begin testing with developers and are expected to be available to the public this fall.

Broader Implications for Apple’s Environment

While the focus of the update is on Siri AI, Apple is also making stricter compatibility decisions for other devices. According to Mac Life, iPadOS 27 and macOS Golden Gate are cutting support for several older iPad and Mac models. In particular, iPadOS 27 will no longer support several iPad Pro, Air, and mini models, while macOS Golden Gate will only run on Macs with Apple Silicon.

Despite these changes, Apple is keeping iOS 27 compatible with the iPhone 11 and newer models, a decision that may be seen as positive for users of older devices. However, for Apple Watch users, the update strategy is more restrictive, reflecting Apple’s broader shift toward newer, more powerful hardware to support its growing AI ambitions.
