The shift to AI-powered Siri leaves older Apple Watch owners needing an upgrade, useful context for a colleague or friend invested in the ecosystem.
WatchOS 27 Drops Older Apple Watches Story flow and key facts
Apple's WatchOS 27 introduces a major upgrade to Siri, now powered by AI to deliver contextual responses, pull data from apps, and reduce reliance on web links. The update also brings improvements to the Smart Stack, Workout Buddy, menstrual cycle tracking, and the Find My app. However, the upgrade is only available on Apple Watch Series 9 and newer, Ultra 2 and newer, and SE 3, cutting off Series 6 through 8, the original Ultra, and SE 2. This marks a sharper compatibility cutoff than in previous years, when older models still received core updates even if some AI features were limited. While Apple cites hardware demands for Siri AI, many new features don’t appear to require the latest processors, raising questions about the decision to exclude recent models. Battery life, a persistent user concern, was not addressed in the announcement, with only vague mentions of potential optimizations.
