Apple’s biggest iPhone event in years is officially in the books. At its September event in Cupertino, the company confirmed the iPhone 18 Pro, iPhone 18 Pro Max, and — for the first time ever — a foldable iPhone called the iPhone Duo. Between a new camera system, Apple’s most powerful chip yet, a rebuilt Siri, and Apple’s long-rumored entry into foldables, this is one of the more substantial iPhone lineups Apple has shipped in recent memory. Here’s everything confirmed, what’s actually new, and what it costs.
What Apple Announced at Its September Event
Apple used its annual fall keynote to introduce three new iPhone models at once: the iPhone 18 Pro, the iPhone 18 Pro Max, and the iPhone Duo, Apple’s first foldable device. All three run iOS 27 out of the box and share the new A20 Pro chip, though the Duo’s software has been specifically adapted for its dual-display foldable design. Apple’s marketing chief Greg Joswiak framed the release as a leap forward rather than an incremental update, pointing to camera, performance, and AI improvements as the areas the company invested in most heavily this generation.
iPhone 18 Pro and Pro Max: Camera, Chip and Battery Highlights
The standard Pro models bring the biggest camera hardware change in several iPhone generations: variable aperture, a first for any iPhone. The new 48MP Fusion Main camera uses six laser-cut blades that shift smoothly between aperture settings, automatically adjusting for depth of field and available light, while also giving photographers manual control over the aperture directly in the Camera app. Apple also introduced Apple Reference Image, a new authenticity feature that signs sensor data at the moment of capture, letting users compare an original image against any edited version later — a direct response to growing concern about AI-edited and AI-generated photos.
The Dynamic Island has been redesigned to display three Live Activities at once, up from two, and both models are available in four finishes: black, silver, glacier, and a new burgundy.
A20 Pro Chip and Performance Gains
Built on a 2-nanometer process, the A20 Pro delivers 50 percent more memory bandwidth than the previous A19 Pro, a GPU that’s up to 40 percent faster, and a dual 16-core Neural Engine that doubles the AI processing power of last year’s chip. A redesigned vapor chamber — with three times the surface area of the one used in the iPhone 17 Pro — helps the chip sustain peak performance for longer under heavy workloads like gaming or video editing rather than throttling.
Battery life sees its biggest jump in iPhone history, according to Apple, particularly on eSIM-only models. The standard iPhone 18 Pro is rated for up to 36 hours of video playback, while the Pro Max reaches up to 45 hours on eSIM-only units. Charging is faster too, with the Pro hitting 50 percent in around 15 minutes on a wired connection.
Siri AI and iOS 27: Apple’s New AI Push
Arguably the most closely watched software announcement is Siri AI, a completely rebuilt version of Siri rolling out in beta with iOS 27. Apple describes it as far more conversational and context-aware, able to draw on a user’s messages, photos, and on-screen activity to actually complete tasks rather than simply answer questions. It launches first in English, with French, Japanese, Korean, Portuguese, and Spanish support arriving in October — though Siri AI won’t be available in the EU at launch, tied to ongoing regulatory considerations there.
iOS 27 also brings broader Apple Intelligence upgrades, including Spatial Reframing and an improved Clean Up tool for photos, a more capable Image Playground for photorealistic image generation, and a Notify Me feature in Safari that tracks web pages for changes like price drops or restocks.
Introducing iPhone Duo: Apple’s First Foldable
After years of patents, leaks, and speculation, Apple has finally entered the foldable phone category — not with the iPhone Ultra or iPhone Fold name that rumors long predicted, but as the iPhone Duo. Rather than following Samsung’s book-style or clamshell approach directly, Apple built a single larger-format design: a 7.6-inch inner display that unfolds into something closer to a small iPad, paired with a 5.4-inch outer display for quick access without opening the device. Both displays share the same aspect ratio, so switching between them shouldn’t require relearning how apps are laid out.
Opened, Apple claims the iPhone Duo is the thinnest iPhone ever made. It runs on the A20 chip, and its software has been adapted specifically for the foldable form factor — Split View allows two apps to run side-by-side on the larger inner display, app pairing saves frequently used two-app combinations, and a new Flex Window mode lets the device operate in a partially folded state for hands-free video calls or media playback. StandBy mode turns the device into a docked widget hub, photo frame, or clock while charging.
iPhone Duo Design, Display and the Crease Question
Both displays use a nano-texture finish to reduce glare, and the frame is built from polished titanium. The closed outer display reportedly delivers around 90 percent of the usable screen area found on the standard iPhone 18 Pro, despite folding down into a compact, pocketable size.
The biggest open question is whether Apple has actually solved the crease problem that has defined every foldable phone released so far — including Samsung’s most recent Galaxy Z Fold models, which reviewers still describe as visibly creased even after years of hinge refinement. Reports ahead of launch pointed to Apple licensing crease-reduction display technology from Samsung Display, built around a metal support plate that distributes folding stress more evenly. Whether that claim holds up under extended real-world use is something only hands-on testing and long-term reviews will be able to confirm.
Camera-wise, the Duo takes a clear step down from the Pro lineup: a 48MP main sensor and an ultrawide lens, with no telephoto camera included. Touch ID also makes a return, built into the side power button rather than relying solely on Face ID — a practical concession given the challenges of using Face ID consistently across a folding design. The Duo also supports the USB-C Apple Pencil, a first for any iPhone, aimed at note-taking, sketching, and more precise creative input on the larger display.
Price and Release Dates for the Entire Lineup
The iPhone 18 Pro starts at $1,199 in the US for the 256GB model, while the iPhone 18 Pro Max starts at $1,299, with both available in 256GB, 512GB, 1TB, and 2TB storage options. Pre-orders for the Pro models open Saturday, September 12, with retail availability beginning Friday, September 18 in more than 65 countries and regions, followed by a wider rollout to 20 additional markets on September 25. iOS 27 becomes available as a free update on Monday, September 14.
The iPhone Duo carries a significantly higher price tag, starting at $1,999 for the 256GB configuration and climbing to $3,199 for the top-tier 2TB model. Pre-orders open October 16, with the device shipping starting October 23 — a full month after the standard Pro lineup, giving Apple extra time to fine-tune production before the foldable reaches customers.
How This Year’s Lineup Compares to iPhone 17
Against last year’s models, the differences go well beyond a routine spec bump. The A20 Pro’s 2-nanometer process and dual Neural Engine represent a bigger architectural leap than last year’s chip upgrade, and variable aperture is the first true hardware-level camera innovation on the Pro lineup in several release cycles, rather than a purely software-driven feature. Battery gains are also more pronounced this year, especially on the eSIM-only Pro Max. Pricing on the Pro models has held steady at the same starting points as the iPhone 17 Pro and Pro Max, which — given industry-wide component cost increases this year — makes the price-to-upgrade ratio notably more favorable than many analysts expected heading into the announcement. The iPhone Duo, by contrast, has no direct predecessor to compare against, since it represents an entirely new product category for Apple.
Which iPhone 18 Should You Actually Buy?
For most buyers, the iPhone 18 Pro or Pro Max will make the most sense — the camera upgrades, performance gains, and battery improvements are substantial without requiring a dramatic jump in price over last year’s models. The Pro Max is the better pick for anyone who prioritizes battery life and screen size, while the standard Pro offers the same core upgrades in a more compact, one-handed-friendly body.
The iPhone Duo is a different kind of purchase entirely — closer to buying a small tablet with phone capabilities than a traditional iPhone upgrade. It’s best suited to early adopters, creative professionals who’ll make use of Apple Pencil support, and anyone specifically drawn to the foldable format, rather than someone simply looking for their next annual iPhone upgrade. Given its significantly higher price and unanswered questions around long-term hinge durability, most buyers will be better served waiting for independent reviews after its October 23 launch before deciding whether the format is worth the premium.
