Apple’s September 2026 event was far more than another routine iPhone launch. The company introduced its first foldable iPhone, upgraded its professional iPhone lineup, pushed Apple Watch deeper into health tracking and gave AirPods another major update.The official lineup included the iPhone Duo, iPhone 18 Pro and iPhone 18 Pro Max, Apple Watch Series 12, Apple Watch Ultra 4 and AirPods 5.But hardware was only part of the story. New camera technology, health sensing, Siri AI and foldable specific iOS experiences could ultimately matter just as much.Here are 10 of the biggest Apple products and features announced in September 2026.
1. iPhone Duo Changes the iPhone Completely
Nothing at the event generated more attention than the iPhone Duo.This is Apple’s first foldable iPhone and one of the biggest changes to the basic iPhone design since the original model.Closed, the Duo offers a compact 5.4 inch outer display. Open it and you get a massive 7.6 inch inner display, the largest Apple has ever fitted to an iPhone.Both displays support ProMotion, Always On functionality and up to 3000 nits of peak outdoor brightness.Instead of requiring buyers to carry an iPhone and a small tablet, Apple is attempting to combine elements of both into one pocketable device.
2. Split View Makes iPhone Multitasking Serious
A folding screen would not mean much without software designed to use the additional space.Apple has therefore reworked parts of iOS 27 specifically for iPhone Duo.Split View allows two applications to run side by side on an iPhone for the first time. Users can also open two windows of the same app, quickly swap applications and save useful app combinations for later.That could completely change certain everyday workflows.You might keep Safari open beside Notes, compare two shopping pages simultaneously or communicate with Siri AI while viewing information on the other side of the display.This could be one of the most important productivity upgrades Apple announced.
3. Apple Pencil Is Coming to iPhone
Another surprising iPhone Duo feature is Apple Pencil support.Apple says its foldable will support Apple Pencil with USB C later in 2026, allowing users to write, sketch and mark up documents directly on either display.That could make the Duo especially interesting for students, professionals and creators.Open the device and it can effectively become a pocket sized digital notebook. Combined with Split View, Apple Pencil support also pushes the Duo closer to functionality traditionally associated with the iPad.
4. iPhone 18 Pro Gets Variable Aperture
The iPhone Duo may be the exciting newcomer, but Apple has not forgotten traditional flagship buyers.The iPhone 18 Pro and iPhone 18 Pro Max introduce a new 48MP Fusion Main camera featuring variable aperture.Variable aperture gives photographers greater control over the amount of light entering the camera and creates new possibilities for controlling depth of field.Apple has also introduced additional Pro controls inside the Camera app, giving experienced photographers more creative flexibility.For content creators and mobile photographers, this could be considerably more meaningful than simply increasing the megapixel count.
5. A20 Pro Pushes Performance Further
Apple’s new A20 Pro powers both the iPhone 18 Pro lineup and iPhone Duo.The Duo implementation includes a six core CPU, seven core GPU and Dual 16 core Neural Engine. Apple says its new architecture delivers significantly stronger performance while supporting demanding AI workloads.Performance matters particularly on the foldable because users may run multiple applications simultaneously.Apple has also introduced advanced thermal management. The Duo uses a custom vapour chamber, while the iPhone 18 Pro models feature a next generation vapour chamber designed to improve sustained performance.For gamers, creators and power users, sustained performance could matter more than short benchmark peaks.
6. Siri AI Becomes Much More Personal
Artificial intelligence was another major theme.Apple’s new Siri AI is designed to be more conversational while understanding personal context and onscreen information.On the iPhone Duo, Siri AI can work with information across messages, emails and photos to help users find what they need. It can also understand content currently displayed on screen and take relevant actions.This is important because smartphone AI is moving beyond generating text and images.The bigger opportunity is creating assistants capable of understanding what users are doing and helping them complete real tasks.If Apple can make that experience reliable, Siri AI could eventually become more important than many hardware upgrades.
7. Apple Watch Series 12 Introduces a New Health Sensing System
Apple Watch Series 12 represents another major step toward making the smartwatch a more intelligent health companion.The new Health Sensing System provides higher frequency heart rate and heart rate variability measurements. Apple says the system delivers its most accurate heart rate sensing in a wearable.The new S11 chip powers these measurements while also enabling additional health and intelligence features.For everyday users, the important change is not simply collecting more data.Apple increasingly wants the Watch to interpret that information and turn it into insights people can actually understand.
8. Readiness Score Helps You Understand Recovery
One of the most interesting Apple Watch Series 12 features is the new readiness score.The feature uses health and fitness information to provide additional context about how prepared your body may be for the day.That could become useful for deciding whether to push harder during a workout or prioritise recovery.Apple is also redesigning the Health app with a new Longevity section that includes Health Age, showing how selected health metrics compare with a user’s chronological age.This reflects a wider trend across wearables.Simply counting steps is no longer enough. Modern smartwatches increasingly attempt to explain what health information means.
9. Apple Watch Ultra 4 Pushes Adventure Battery Life
Apple Watch Ultra 4 continues to target serious athletes and outdoor enthusiasts.Apple says Ultra 4 delivers the longest battery life of any Apple Watch and offers up to 45 hours of Max Extended Workout tracking.That matters for long hikes, endurance events and outdoor adventures where regular charging may not be practical.For everyday smartwatch users, Apple Watch Series 12 will probably remain the more sensible choice.But runners, hikers, cyclists and endurance athletes who rely heavily on workout tracking could appreciate the additional endurance offered by Ultra 4.
10. AirPods 5 Improve Noise Cancellation and Sound
AirPods 5 may look like a smaller announcement beside a foldable iPhone, but they could become one of Apple’s most widely used new products.Apple says AirPods 5 provide up to 1.5 times more Active Noise Cancellation than the previous generation while introducing a new acoustic architecture designed to improve sound quality.That is particularly interesting because AirPods maintain the familiar open ear approach that many users find more comfortable than deeply sealed earbuds.Better noise cancellation could make them more practical for commuting, office work and travel while preserving that lightweight everyday experience.
Which Announcement Actually Matters Most?
The iPhone Duo clearly wins for innovation.Apple entering the foldable smartphone market could influence the entire industry and potentially make foldable phones much more mainstream.However, the feature that matters most will depend on the buyer.Creators may care more about the iPhone 18 Pro variable aperture camera. Fitness users could find Apple Watch Series 12 and its readiness insights more useful. Frequent travellers may appreciate AirPods 5 or the improved endurance of Apple Watch Ultra 4.The most important announcement is ultimately the one that improves something you already do every day.
