The anticipation for the Apple Watch Ultra 4 is building as it promises to introduce some significant changes to Apple’s wearable lineup. Unlike its predecessors, the Ultra 4 is rumored to include advanced biometric capabilities and an updated design.

Apple Watch Ultra: fingerprint integration remains speculative

Incorporating a fingerprint reader into Apple’s watch has been a frequently discussed topic. The Ultra 4 could potentially integrate Touch ID into the Action or side buttons. However, as Bloomberg’s Mark Gurman points out, this innovation might not be part of the upcoming model. Instead, users can expect a new chipset, enhanced health features, and improved battery life within the existing design framework.

Streamlined authentication on the horizon

Currently, Apple Pay on the Ultra requires a double press of the side button—a cumbersome process for those engaged in active sports. Integrating Touch ID could address this annoyance by making payment authentication smoother. Nevertheless, incorporating such technology presents engineering challenges, particularly for devices exposed to the elements.

Sensor upgrades and improved measurements

The Ultra 4 might boast up to eight sensors on its back, advancing beyond the current capabilities of heart rate, SpO2, temperature, and ECG tracking. The emphasis seems to be shifting towards precision hardware measurements, crucial for activities like altitude training. A thinner titanium case will also offer increased comfort, addressing complaints about bulkiness during sleep tracking.

Efficiency gains and smarter software

Battery life should see slight improvements, thanks to chip efficiency, maintaining the Ultra 3’s baseline of 42 to 72 hours. Additionally, watchOS 27 will introduce an enhanced Siri and new women’s health tracking features. Although a round watch design and a screenless fitness tracker are rumored for future generations, the Ultra 4 remains focused on refining its core strengths with or without Touch ID.
