The Apple Watch Series 12 is the start of a new wearable era

The Verge published a review of Apple Watch Series 12: design unchanged, but inside is a new S11 chip with a secure enclave for audio processing and a redesigned sensor array. Heart rate is now measured every 5 seconds instead of 5 minutes, charging from 20 to 64% takes 20 minutes, and some AI features will arrive later this fall.

• S11 chip speeds up Siri and processes audio in a secure enclave
• Heart rate measured every 5 seconds, accuracy within 5 bpm of Polar H10
• 20 minutes of charging increases battery from 20 to 64%
• Some AI features like Audio Intelligence and a new Health section will arrive later
