Future Apple Watch Ultra might get satellite emergency messaging & hypertension detection
Apple's third-generation Apple Watch Ultra is expected sometime in 2025, and is rumored to include satellite messaging, along with some form of hypertension monitoring.
The Apple Watch Ultra third-gen should arrive in 2025 with new features.
The upgrade to self-contained satellite communication would enable users to rely less on their iPhones for messaging and emergency calls in remote areas, potentially lightening the load for outdoor enthusiasts. The feature is likely to be exclusive to the third-gen Apple Watch Ultra, the current generation of which retails for $799.
To be clear, the addition of satellite communication and geolocation features in the Apple Watch Ultra would assist with emergency situations, but not replace the overall usefulness of the iPhone. It would, however, make it easier to summon help quickly, if needed, by having the device already available on one's wrist, rather than packed away.
Hypertension alerts may also be coming soon
The next Apple Watch Ultra -- as well as possibly the regular annual Apple Watch update in 2025 -- could also see the long-awaited debut of a new medical feature: hypertension detection. Current thinking, as reported by Bloomberg, is that the feature would not provide traditional blood pressure readings.
Instead, the feature would simply send alerts when users are in a state of hypertension, similar to how the current sleep apnea alert feature works. Rather than provide specific blood-pressure results, it would simply alert users when blood pressure is outside of a normal range.
Traditional blood pressure monitoring devices rely on a cuff strapped around the upper arm. The cuff is then inflated to put pressure on the area, making the heart's systolic and diastolic circulatory pumping more easily detectable.
Apple's present aim is to have future Apple Watch models monitor trends, alerting users to changes. The alerts would then suggest traditional blood-pressure cuff readings and physician assistance to confirm the information.
This is similar to how future non-invasive blood glucose readings from the Apple Watch -- another feature Apple hopes to introduce in the future -- would work. Rather than offer blood-sugar readings, light sensors on the bottom of the Apple Watch would analyze changes in blood chemistry, with a method use similar to the way the device currently measures pulse rates to determine trends.
Other more invasive devices already exist to help those with diabetes and similar conditions monitor their blood glucose levels. The Dexcom G7 glucose meter, for example, uses a disc with a small needle in it that adheres to the skin to directly read blood glucose levels.
These devices then wirelessly transmit the information gathered directly to the iPhone or Apple Watch.
The two future Apple features would combine to further position the Apple Watch as a mainstream health and safety device, rather than a medical device. This approach would still provide users with useful health and communication abilities, while avoiding having health features delayed or not included due to regulatory and other technical challenges.

If I’m out hiking, listening to music and using my watch as the GPS with occasional iMessage it’s dead within 3-4 hours if my iPhone is not present.
If I could get 18 Hours+ with that type of usage I’d probably upgrade.
A good friend who owns an Apple Watch Ultra told me that his watch does last significantly longer, but would also be dead within hours without his iPhone handling the cellular/GPS element.
