Apple Watch Series 12 review: Upgraded where it was needed

Apple has unveiled the Apple Watch Series 12, a refined iteration of its popular smartwatch lineup. The new model maintains the familiar design of its predecessor, the Apple Watch Series 11, but introduces significant enhancements under the hood.

One of the most notable upgrades is the Health Sensing System. This system replaces the previous sensors with larger electrodes and photodiodes, promising more accurate and frequent health measurements. The new array is particularly evident when you first glance at the back of the watch, where the sensor layout is more pronounced.

Apple also introduces a new feature called Readiness score, which provides users with a daily score based on their health and vital data. This score updates throughout the day and can guide users on whether to engage in physical activity or rest, especially beneficial for athletes who need to balance performance with injury prevention.

The watch maintains its 24-hour battery life and extends this to 38 hours with Low Power Mode. A 15-minute charge can provide up to 12 hours of use, with a five-minute charge lasting for 10 hours of sleep tracking. This makes the Apple Watch Series 12 a reliable companion for daily wear.

While the Audio Intelligence features are still forthcoming, they include Live Rewind, which transcribes the last 15 seconds of captured audio, and Siri Recap, which creates a running record of conversations throughout the day. These features are expected to enhance the user experience, though their practicality remains to be seen.
