Apple's watchOS 27 Siri Routes Requests Through iPhone for Consistency

Apple's new Siri on watchOS 27 processes requests through a paired iPhone rather than locally on the Watch. The trade-off: sacrificing hardware isolation for unified conversation history and identical responses across devices. Early adopters report noticeable processing latency—friction on a device built for quick interactions. Apple prioritizes parity: users should receive the same answer whether querying the wrist or phone.
