Apple Watch Series 12 review: What's new and whether it's worth upgrading (www.businessinsider.com)

The Apple Watch Series 12 has been unveiled, marking a significant transition for Apple's wearables as it integrates a range of artificial intelligence features aimed at transforming the smartwatch into a more capable AI assistant. This new model boasts major upgrades, including the powerful S11 chip that enables advanced capabilities like enhanced heart rate tracking every five seconds and burgeoning Audio Intelligence functionalities. Despite these improvements, critics have voiced skepticism about the practicality of features like Live Rewind and Siri Recap, which rely on continuous audio processing, raising potential privacy concerns. While the Series 12 presents noteworthy advancements, including a more resilient design with new materials and faster charging, many of its cutting-edge features are not fully available at launch. Upgraded health tracking capabilities, contingent on wearing the watch overnight, aim to deliver deeper insights into user wellness but may be underutilized by those unwilling to adjust their wearing habits. The watch is well-suited for newcomers or those with older models, but existing Series 9 owners might find little incentive to upgrade immediately, as many new functionalities will also roll out in a software update for compatible previous models.
