The recent rumors surrounding a fingerprint sensor in the Apple Watch have been shelved for now. A leaker with a solid track record claims that Apple has scrapped the idea for two specific reasons – and is instead setting clear priorities for the next generation.

For years, the idea of integrating Touch ID into the Apple Watch has been circulating in the rumor mill – sometimes in the Digital Crown, sometimes under the display, and most recently even as a strong contender for the Apple Watch Ultra 4. As early as 2020, an Apple patent application hinted in this direction, and in the summer of 2025, leaked code snippets seemed to practically confirm the feature's return. Now, however, the Chinese leaker Instant Digital has spoken out, claiming that Cupertino has abandoned the idea.

Apple Watch: Two reasons for the alleged cancellation

According to Instant Digital, the decision is based on two key considerations. The first concerns battery life: an additional biometric sensor would strain the already limited power consumption of the Apple Watch. The second aspect is cost – a fingerprint sensor increases the cost of the components without significantly expanding the functionality from Apple's perspective. Apple continues to pursue its strategy of unlocking the smartwatch via iPhone pairing. Therefore, instead of investing resources in biometric authentication on the wrist, attention is currently focused in two other directions: larger batteries and more sophisticated health sensors.

What the code leak from summer 2025 really meant

To put this into perspective, it's worth taking a look back: In August 2025, leaked code hints suggested an imminent Touch ID integration. The codename “AppleMesa” – Apple's internal designation for Touch ID – appeared exclusively in code entries relating to Watch models from 2026. early hints of an Apple Watch with Touch ID At the time, this was seen as a strong indication of a market launch in the coming year.

But this is precisely the crux of the matter: internal code traces don't automatically signify a final product decision. Apple regularly tests features in its software that don't ultimately make it into final devices. The statement now circulating from Instant Digital suggests that while the feature was researched, it wasn't ultimately released.

How reliable is Instant Digital?

Instant Digital's track record is mixed. Some of their earlier predictions proved correct - such as the yellow color variant of the iPhone 14 and 14 Plus, and the titanium Milanese Loop for the Apple Watch Ultra 2. Other predictions, however, were inaccurate. Nevertheless, the leaker is considered a source that frequently has early access to internal information and is therefore not ignored. Those hoping for a fingerprint sensor on the wrist, however, shouldn't prematurely consider this new assessment as definitive - just as they shouldn't consider previous leaks.

Battery and health as Apple's main focus

More intriguing than the Touch ID denial is Apple's apparent focus. Larger batteries have been a recurring request in the community since the first Apple Watch – while the Ultra 3 already delivers a top-notch battery life of up to 42 hours, there's still room for improvement compared to Garmin models or other outdoor smartwatches. An additional sensor would likely be a hindrance in this regard.

On the health front, evidence is mounting for a significant expansion of the sensor capabilities. The Apple Watch Series 12 is already expected to feature enhanced health functions, and in conjunction with the persistent rumors of sensor doubling, it's easy to guess what Cupertino is prioritizing. Features like more reliable hypertension detection, optimized SpO2 measurement, or new activity and sleep metrics would be far more consistent with this strategy than a mere authentication convenience feature.

From our perspective

Touch ID on the wrist sounds tempting – who hasn't experienced the frustration of their watch asking for a PIN code when putting it on under a sweater? Nevertheless, rejecting it fits perfectly with Apple's established approach: The Apple Watch is designed as a companion device to the iPhone, and authentication via the smartphone works flawlessly in most everyday situations. While a standalone biometric sensor would offer additional independence, it would also require space, energy, and cost resources that are more urgently needed elsewhere.

Furthermore, Apple is increasingly positioning the Watch as a health and fitness device, not as a mini-iPhone. This focus is expected to intensify under Tim Cook's designated successor, John Ternus. Anyone who has followed recent product announcements will recognize the pattern: each new Watch generation emphasizes new measurement methods and longer battery life, rather than additional biometric security layers.

What might happen with Touch ID on the Apple Watch?

The idea isn't completely off the table, however. Apple patents and code hints have repeatedly shown in the past that Cupertino researches features for years before they are actually released. Should Apple find a technical solution in the coming years that doesn't significantly impact battery life or unit costs, the topic could quickly resurface. Until then, iPhone unlocking is likely to remain the primary way to authenticate the Apple Watch in everyday use. (Image: Shutterstock / Sashkin)
