Designs & Colours: What’s New
The Apple Watch Ultra 4 sticks to the classic design that has defined the Ultra lineup. It brings back a familiar rectangular display and titanium build, but with minor upgrades such as a larger and brighter screen. The company is also putting effort into sustainability, stating that the new wearable is made up of 45% recycled materials, with the titanium case made entirely from recycled titanium.
In terms of finishes, Apple is offering two different options: Natural Titanium and Black Titanium. The company has also introduced new colour options for Trail Loop, Alpine Loop, and Ocean Bands, which means more customisation options for users. For those who want a premium touch, they can also choose the Apple Watch Hermes edition. This one comes with a Grand H titanium band featuring a built-in extension system.
Battery and Charging: A Major Battery Boost
Apple has gone all out when it comes to the battery life upgrades for Apple Watch Ultra 4. Now, users will be able to get 50 hours of battery life under normal use, which means just a single charge can get you around two days of use.
Those who switch to Low Power Mode can expect the wearable to last up to 84 hours. Apple has also brought in improvements to the Extended Workout and Max Extended Workout modes, which make Apple Watch Ultra 4 the right choice for longer activities and endurance workouts.
Charging speeds have also been given a look. Now, Apple Watch Ultra 4 can get 18 hours of additional battery life with just 15 minutes of charging. Users will now be able to easily top up their wearable whenever they’re running low, and quickly get back into the action.
Performance: New S11 Chip
Under the hood of the Apple Watch Ultra 4 is the new S11 chip. This features a 4-core Neural Engine and 64GB of storage. As you’d expect, Apple has dubbed it its most powerful chip ever used in a wearable. While that might not sound like much on paper, it’s actually the foundation for many of Ultra 4’s new health, audio, AI, and tracking capabilities. The chip is also responsible for the new Siri experience in watchOS 27.
Health Sensing System
The major highlight of the Apple Watch Ultra 4 is its new Health Sensing System. It’s powered by the wearable’s sensors, S11 chip, and advanced algorithms to collect and interpret health data. Now, the watch can take your heart rate readings every five seconds, which gives it more data to analyse and monitor your heart throughout the game.
The system also brings frequent heart-rate variability (HRV) measurements into the play, which will give users a great understanding of their body’s overall wellness and recovery. This works right alongside the Readiness score, which will estimate how well a person is prepared for the day ahead. Apple has also made upgrades to step tracking, which means it will be more accurate than ever before.
Audio Intelligence
Another thing that’s worth keeping an eye out for is Audio Intelligence. What’s this about? Well, it makes use of the wearable’s built-in microphone, the new S11 chip, Apple Intelligence, and other components to bring four unique features to the table:
- Sound Recognition: If you’re someone who leaves your iPhone behind, the Ultra 4 can now detect important sounds such as doorbells, sirens, and alarms, and send you an alert.
- Live Rewind: Missed something in a conversation? A double press of the Digital Crown will let you pull up a text snippet of the previous 15 seconds.
- Siri Recap: Apple Intelligence can now summarise everything you’ve been discussing with someone else and give you a summary.
- Shazam: You no longer have to wonder what song is playing around you. The wearable can identify the track and display the result.
Of course, a wearable listening to conversations and sounds around you raises privacy concerns. However, Apple has assured that Audio Intelligence isn’t designed to record and store things. The S11 chip comes with a Secure Enclave that keeps all the audio processing completely isolated. Once it’s been used, the audio will be instantly deleted.
Availability and Pricing
Despite speculation that the current hardware shortages and rising prices could push the Apple Watch Ultra 4 price sky-high, Apple has kept things unchanged. The wearable starts at $799 in the U.S, which matches the launch price of its predecessor.
When it comes to monthly plans, the Ultra 4 can be financed at $66.58 per month over 12 months. Pre-orders are now available live in more than 50 countries, and the wearable will officially hit the stores on September 18, 2026.
Final Thoughts: Should You Upgrade?
The biggest question now is whether or not the Apple Watch Ultra 4 is worth the upgrade. Ultimately, that comes down to what you’re looking for from your wearable. If a longer battery life, more advanced health tracking, and new Audio Intelligence features are important to you, the Ultra 4 is undoubtedly a good pick.
However, if you’re someone already rocking a previous-generation Apple Watch Ultra, there’s no reason to upgrade. Sure, the Ultra 4 does bring major improvements, but they don’t completely change the experience or design. However, if you’re someone coming from an old Apple Watch, the Ultra 4 has enough features to make the upgrade completely worth it.
