Powered by S9 SiP
The double-tap feature, available on Apple Watch Series 9 and Apple Watch Ultra 2, is powered by the S9 SiP, which is 25% more efficient than the previous generation, and the new 4- core, which can perform machine learning tasks twice as fast.
The Neural Engine processes data from the accelerometer, gyroscope, and optical heart rate sensor using an innovative machine learning algorithm. The algorithm detects wrist movements and changes in blood flow when the index finger and thumb perform a double tap.
Double-tap works when the screen is on, and is available throughout the day, with minimal impact on battery life. Specifically, it offers 18 hours of battery life on the Apple Watch Series 9 and 36 hours on the Apple Watch Ultra 2.
Double-tap function adjustments
Double-tap is designed to automatically select the primary action for most apps and notifications. In both cases, the user has the option to choose between two different functions. They can browse through widgets in the Smart Stack or select the first available widget as well as play or pause media, or even skip to the next track during an active session.
