Apple Watch Ultra, outside of a very nice new titanium black, hasnt been meaningfully upgraded since 2023. But later this year thats going to change when the Apple Watch Ultra 3 arrives. Here are three new features coming to the Apple Watch Ultra 3.High blood pressure detectionNew health features are one thing you can consistently expect from Apple Watch upgrades. According to Mark Gurman, this year Apple is planning to introduce high blood pressure detection:The blood-pressure featureis designed to work in a similar way to Apples sleep apnea detector. It wont give users specific readings such as diastolic or systolic levels but it will inform them that they may be in a state of hypertension.Gurman notes that this project has been years in the making, and has faced delays before, but a launch this year is currently planned.Satellite messaging sans iPhoneApple Watch Ultra has always been geared toward adventurers and explorers, despite the product gaining plenty of fans with more casual needs. With the Ultra 3, Apple will add a new capability designed especially for those who enjoy going off the grid.Messaging over satellite is coming to the Apple Watch Ultra 3.Heres Gurman again:The technology will let smartwatch users send off-the-grid text messages via Globalstar Inc.s fleet of satellites when they dont have a cellular or Wi-Fi connection.iPhone users have had this technology for a few years, and it got even better with a critical iOS 18 update. The Apple Watch, however, has never gotten its own satellite connectivity. With the new Ultra 3 it will be easier than ever for users to leave their iPhone behind to truly embrace the outdoors.5G cellular for the first timebetter battery life that's the biggest factor to upgrade, let the watch go all the way to 72h at least. if they can do that I will definitely buy it. if they can do that plus something else I would like a more conformable form factor. on the software side they should let you use the watch buttons only when you are working out.

Whereas previous Apple Watch Ultra models have been limited to 4G LTE connectivity, Apple plans to bring 5G to the Ultra 3 this year.This upgrade will reportedly take the form of 5G Redcap, a less power-hungry version of 5G. Redcap cant hit the same max speeds as your iPhones 5G, but it will ensure your Watch doesnt take a big battery hit either.Apple Watch Ultra 3 wrap-upThe new Apple Watch Ultra 3 isnt expected to arrive until the fall, so theres still plenty of time for additional feature leaks to happen. Perhaps well get even better battery performance this time around, for example. But for now at least, it sounds like Apple is doubling down on the Ultra 3 as the ultimate Watch for adventurers.What new features do you want to see in the Apple Watch Ultra 3?
