Apple has reportedly abandoned plans to add Touch ID to its smartwatch despite previous patents and leaked code suggesting otherwise. According to a reliable leaker, the tech giant decided against integrating the biometric authentication feature into the Digital Crown of the Apple Watch, despite initial development work and patent filings from 2020.

The decision stems from two primary concerns: cost considerations and battery life impact. With component expenses rising, adding another sensor would increase production expenses. Additionally, the processing circuitry required for Touch ID would occupy space currently used for battery capacity, potentially reducing the device's endurance—a critical factor for wearable electronics.

This shift suggests Apple prioritizes battery improvements and advanced health sensors over biometric authentication for its smartwatch. The current authentication method relies on iPhone pairing rather than standalone biometric security, indicating Apple sees greater value in extending battery life than in adding Touch ID functionality.
