After several days testing the Apple Watch Series 12, a reviewer highlights the new S11 chip as a major speed boost, especially noting Siri now runs smoothly under watchOS 27. The device also gains new health complications—Heart Rate, Daily Steps, and Readiness—thanks to an updated Health Sensing System, plus quicker charging that delivers up to 12 hours of battery from just 15 minutes on the charger.

Apple had gone two years without a meaningful chip upgrade, so the S11's performance gains matter for how well on-device AI features like Siri actually function. The added health complications and faster charging address two of the most common wearable complaints—data visibility and downtime—making the watch more useful for daily health tracking.
- S11 chip delivers a notable speed jump, especially benefiting Siri responsiveness
- New Health Sensing System enables Heart Rate, Daily Steps, and Readiness complications
- Charging is nearly 50% faster, giving 12 hours of battery from a 15-minute charge
