TL;DR: Apple introduced its first foldable phone, iPhone Duo, alongside the iPhone 18 Pro line, new watches and AirPods 5 at its September 9 “Surprise and Shine” showcase in Cupertino.

What happened on September 9

Apple staged its annual fall hardware showcase on Wednesday, September 9, 2026, under the name “Surprise and Shine,” according to CNBC live coverage of the event. The presentation ran for more than an hour and, according to MacRumors, covered the iPhone 18 Pro and Pro Max, the foldable iPhone Duo, revised Apple Watch models and AirPods 5.

The keynote was the company’s first major launch led by Chief Executive John Ternus, according to Reuters. Reporting from Tom’s Hardware likewise described the gathering as the first iPhone event led by the newly elevated chief executive. Apple’s own announcements dated the introductions to Cupertino, California, on September 9.

Market reaction during the broadcast was muted. CNBC reported that Apple shares opened at $315.49, briefly touched $318, then slipped and remained lower for almost the entire near-80-minute program. Year-to-date the stock was still up about 15%, according to that same live report.

Why the Duo mattered most

The closing reveal was the foldable iPhone Duo, Apple’s first entry in the category, according to CNBC. Ternus framed the choice as a response to demand for a bigger screen on a device that remains central to daily life, saying the company viewed a folding design as the best path forward.

He contrasted Apple’s approach with existing rivals, saying other foldables feel like two phones awkwardly stuck together, according to CNBC. In Apple’s press release for iPhone Duo, Ternus called the model the most transformational change to iPhone since the original, arguing that joint hardware and software engineering redefines use of a foldable phone.

According to Reuters, the Duo represented the largest redesign of the iPhone line in years. MacRumors summarized the device as passport-shaped when shut, opening into a tablet-like canvas, a description consistent with Apple’s comparison of the closed phone to passport dimensions.

Two screens, titanium shell and a new hinge

Apple said the Duo pairs a 5.4-inch outer Super Retina XDR screen with a 7.6-inch inner Super Retina XDR screen, according to Apple. The outer panel supplies 90 percent of the screen area of iPhone 18 Pro, while the inner panel is 50 percent larger than iPhone 18 Pro Max, Apple reported. Both panels share the same aspect ratio so material scales proportionally between closed and open states.

The two displays include ProMotion, Always On and up to 3,000 nits of peak outdoor brightness, according to Apple. The inner surface uses a nano-texture finish intended to cut glare and reduce the visibility of the fold, while a FaceTime camera stays concealed beneath that panel when idle.

Durability was a central message. The enclosure uses grade 5 titanium polished to a mirror finish, with a 3D-printed hinge cover in a contrasting micro-blasted finish, according to Apple. Ceramic Shield protects the back, while Ceramic Shield 2 on the front improves scratch resistance by three times over the prior generation. The phone carries an IP68 rating for splash, water and dust resistance, distinguishing it from Samsung’s Galaxy Z Fold8, according to MacRumors.

Apple described a precision hinge assembled from more than 100 components that supports the center of the display to hold it flat, aided by an integrated magnet array for secure closure. Inside, support ribs add stiffness and ceramic-fiber antenna splits reinforce rigidity. High-strength glass sits above and below the folding panel, with custom adhesives that let layers glide like book pages to relieve bending stress, according to Apple.

Authentication moves to Touch ID built into the side button for consistent use open or closed, with Apple Watch unlocking also supported, according to Apple. CNBC added that the side-button sensor handles unlocking and that the chassis uses titanium. A Camera Control button launches the camera, including a Siri Camera mode in which Siri can view the scene to answer questions and act.

Software reworked for folding

Apple said iOS 27 was reimagined for Duo while remaining familiar, according to Apple. Craig Federighi, senior vice president of Software Engineering, said the team reviewed every part of iOS to improve usefulness on the new form factor, according to CNBC.

Buttons and controls were repositioned for two-screen operation. Users can run two apps at once on the large display, according to Reuters and CNBC. Later this year Duo will support Apple Pencil with USB-C for notes, sketching and markup on either screen, according to Apple. MacRumors noted the phone works only with the $79 USB-C Apple Pencil, not Apple Pencil Pro, and will ship with iOS 27.1.

Intelligence features are built around Apple Intelligence 2 and Siri AI, according to Apple. The company presented iPhone as the best device for AI because of access to personal context such as calendars and habits, while emphasizing privacy, according to reporting from Ars Technica on the presentation.

A20 Pro and C2: silicon at the center

Both Duo and the 18 Pro line run on the new A20 Pro, Apple’s first 2-nanometer smartphone chip, according to Tom’s Hardware. The design uses a new architecture shared in concept with the M6, with a six-core CPU combining two desktop-class super cores and four efficiency cores, according to reporting from The Verge.

Graphics move to a seven-core GPU described as delivering about 40 percent higher performance, according to The Verge. Ars Technica reported the two super cores run up to 20 percent faster, with increased bandwidth on the graphics side. Apple added a second neural engine for 32 NPU cores in total to accelerate on-device AI, according to The Verge.

Thermal design received unusual attention. Apple paired the chip with a vapor-chamber system, described by Reuters as a vapor-chamber cooling system aimed at on-device AI and graphics. The Verge reported the 18 Pro chamber offers three times the surface area of the 17 Pro unit. Rich Dinh, vice president of hardware engineering, linked the arrangement to sustained performance, while Apple said Duo uses a custom vapor chamber plus dual-battery architecture for all-day use.

Connectivity brings Apple’s second in-house modem, C2, debuting in Duo and the Pro phones. Johny Srouji, chief hardware officer, said the fully integrated approach uses AI algorithms to improve reliability, including faster reconnection in weak coverage, according to CNBC. The unit is 50 percent faster than its predecessor, adds 5G mmWave support in the United States and runs at 15 percent lower energy, according to CNBC and The Verge. Chip analyst Ben Bajarin told CNBC he expects Apple to remove Qualcomm parts entirely in the following year’s iPhone 19 line.

iPhone 18 Pro: camera, battery and price

The conventional flagships, iPhone 18 Pro and Pro Max, arrive in black, silver, glacier and burgundy with color-matched back glass, according to The Verge. Apple’s announcement highlighted a smaller Dynamic Island capable of showing three Live Activities at once.

Photography is the headline change. Both models carry a 48-megapixel Fusion Main camera with variable aperture, the first aperture control on iPhone, according to Apple. Six laser-cut blades shift smoothly across four selectable settings, adjusting automatically for depth and light or manually through new Pro controls for aperture, shutter speed, white balance and histogram, according to Apple.

Apple said the wider ƒ/1.48 setting aids low-light capture and faster Night mode, while ƒ/1.8 targets balanced portraits and ƒ/4 keeps groups sharper, according to Apple’s imaging breakdown. A new sensor and computational pipeline promise sharper detail, upgraded Photographic Styles add texture and grain controls, Cinematic effects can be applied after capture at up to 60 frames per second, Time-lapse now records in 4K Dolby Vision HDR, and Audio Mix can isolate music with cleaner voices, according to Apple.

Trust features include Apple Reference Image, which signs sensor data and develops an unalterable reference through Private Cloud Compute for viewing beside the main shot like a digital negative, according to Apple. The Verge noted support for Google’s SynthID authenticity protocol as well.

Battery claims are large. Video playback is rated at 36 hours for 18 Pro and 45 hours for 18 Pro Max, with 15 minutes of wired charging restoring half a charge on the smaller model and five minutes yielding seven hours of video on the Max, according to The Verge. Apple said the Max delivers the largest battery-life jump ever on iPhone.

Pricing starts at $1,199 for 18 Pro and $1,299 for Pro Max, each with 256GB base storage and options to 2TB, according to MacRumors. That is $100 above the equivalent 17 Pro pricing, a smaller rise than many summer forecasts, according to MacRumors. Pre-orders begin Saturday, September 12 at 5 a.m. Pacific, with availability September 18, according to MacRumors and Apple. Carrier trade offers tied to iPhone 14 or newer can reach $1,200 in credit, according to Apple’s September 11 shopping update.

Watch and AirPods round out the day

Apple Watch Series 12 starts at $399 and Ultra 4 at $799, with no increase, plus a new ceramic-case option, according to CNBC. The Series 12 uses the S11 chip and Health Sensing System with optical and electrical heart sensors, measuring heart rate every five seconds and heart-rate variability far more often to feed a new readiness score, according to Apple. A Longevity tab with Health Age in the redesigned iPhone Health app arrives later in the year.

New Audio Intelligence tools due later this year use the watch microphone for 15-second live rewind and Siri Recap summaries built on ambient listening, according to CNBC. Apple stressed privacy, security and accessibility in that design.

AirPods 5 bring open-ear active noise cancellation that removes up to 50 percent more external sound than AirPods 4 with cancellation, alongside clearer Transparency, Adaptive Audio and Conversation Awareness, according to Apple. Pricing is $129, or $149 with a wireless charging case, longer battery and stem volume control, according to Apple. Pre-orders opened at announcement with September 18 availability. Hands-free Siri AI, head-gesture responses and Live Translation across the AirPods range were highlighted as system-level additions.

What comes next

Pre-order timing splits the lineup. Watches and AirPods were available to order immediately after the showcase, with store arrival September 18, while 18 Pro orders open September 12 ahead of that same September 18 date, according to MacRumors and Apple. Duo follows later, with pre-orders October 16 and launch October 23 at $1,999, according to CNBC and MacRumors. Developer videos for Duo adaptation were also published, according to MacRumors.
