The Apple Watch Ultra 3 is anticipated to launch later this year, marking a two-year gap since its predecessor. While the design is expected to remain largely unchanged, significant internal upgrades are rumored, particularly for users upgrading from the first-generation Ultra.
One of the most notable additions could be hypertension detection, as reported by Bloomberg’s Mark Gurman. The feature would not provide exact blood pressure readings but instead track trends and alert users if levels rise dangerously. This could be a lifesaving tool, as hypertension often goes undetected until severe complications arise. The Apple Watch already monitors irregular heart rhythms and offers ECG capabilities, though its blood oxygen sensor remains disabled in the U.S. due to patent disputes.
Brighter Display and Faster Refresh Rate
The Ultra 3 is likely to adopt the advanced LTPO3 OLED display technology introduced in the Apple Watch Series 10, offering a faster refresh rate and improved brightness at wider angles. This would bring the Ultra in line with the Series 10’s display enhancements, including a smoother always-on mode with a live seconds hand.
New Chip and Potential Performance Boost
With no hardware refresh in 2024, the Ultra 3 is expected to feature an upgraded chip—possibly the S11—which could improve efficiency or introduce new capabilities. A more compact chip might also free up space for a larger battery or other components.
Satellite Connectivity for Off-Grid Safety
Apple is reportedly adding satellite connectivity to the Ultra 3, a feature currently limited to iPhones. This would allow users to send emergency texts without cellular or Wi-Fi coverage, expanding safety for hikers, divers, and adventurers. While Apple currently offers free satellite service for iPhones, pricing for the Ultra remains unclear.
5G Support and Modem Switch
The Ultra 3 may replace Qualcomm’s modem with a MediaTek chip, enabling 5G RedCap—a power-efficient 5G variant ideal for wearables. Current cellular Apple Watches still rely on 4G LTE, despite iPhones supporting 5G since 2020.
Redesigned Back and Faster Charging
A new metal back, similar to the Series 10’s design, could improve cellular performance and charging speeds. The Ultra 2 currently takes an hour to reach 80% battery, while the Series 10 achieves it in just 30 minutes.
The Ultra 3’s upgrades aim to solidify its position as the ultimate smartwatch for extreme conditions, with health, connectivity, and performance enhancements driving potential upgrades. Apple is expected to unveil the device in September.
