Yesterday, Apple announced the 2026 iPhone models, and it was a fascinating announcement. The iPhone 17 was replaced with … nothing. The iPhone 17 Pro and Pro Max were replaced with the iPhone 18 Pro and Pro Max, and the Pro Max is not only a larger size but also the only model with a brand-new variable aperture lens, a first for an iPhone. And not to bury the lede, but there is also the incredibly different iPhone Duo, a folding iPhone that is the most radical change in iPhone design since the original iPhone debuted in 2007.
The iPhone 18 Pro and 18 Pro Max
If you want a better version of the more traditional iPhone design, the 18 Pro and 18 Pro Max are for you. And indeed, I think that this is the design for me.
In 2001, John Markoff of the New York Times wrote that then-Apple CEO Steve Jobs predicted that the Mac “can become the digital hub of our new digital lifestyle.” The idea was that the Mac and Apple software would be the center of everything that you would do with music, video, photos, and more. Yesterday, Apple CEO John Ternus updated that concept, saying that today, what we want is an intelligent personal hub. “It’s the intersection of broad new capabilities and a deep understanding of your personal context that makes this idea so powerful.” He said that you want something that is “always with you, deeply personal, and able to bring intelligence to the moments when it matters most.” And he said that the iPhone is the perfect intelligent personal hub because of its powerful on-device processor, the ability to take advantage of secure AI in the cloud, a large, beautiful display, the ability to work with the sights and sounds of the world around you, all-day battery life, an easy-to-use interface, and integration with other devices, apps, and services. It’s a compelling pitch, and one that the new iPhone 18 Pro and Pro Max are ready to deliver.


A20 Pro chip. The heart of the new iPhone is a new processor built on two-nanometer technology. Processor technology gets smaller and more efficient over time. At one point, people measured a transistor’s gate length (one of its key components) in nanometers, so a chip with fewer nanometers was smaller. Nowadays, chips are so sophisticated that no single dimension matters, so chip designers instead describe a smaller design as an X-nanometer process. It’s as much a marketing term as anything else, but it is a way to note advancements. Last year, Apple said that the iPhone 17 Pro used an upgraded 3-nanometer process.
This year, the A20 Pro chip is said to use a new 2-nanometer process. Here is how Apple describes it:
Built using the latest 2-nanometer process technology, A20 Pro sets a new bar for mobile computing. Featuring 50 percent more memory bandwidth than A19 Pro, the new 6-core CPU features integrated Neural Accelerators and is faster than the competition, while the new 7-core GPU design is up to 40 percent faster than A19 Pro — a significant upgrade for graphics rendering. A20 Pro also features a new Dual 16-core Neural Engine, which accelerates on-device AI models and computational photography, and includes 32 total cores for double the AI processing power of A19 Pro. With huge upgrades across the entire chip, A20 Pro is a powerhouse for everything from more advanced on-device AI workloads to demanding games, and is designed to deliver exceptional performance for years to come.
All that you really need to know is that it has better performance (so it can do more) and it is more efficient (so it uses less battery). Apple says that thanks to the A20 Pro, the new iPhone has 40% improved sustained performance over last year’s iPhone.
A faster and more efficient iPhone is always a better iPhone. But this year, I think that the new processor will be especially important. Returning to the idea of an intelligent digital hub, Apple AI is a key part of iOS 27, and the incredible A20 Pro processor is especially good at handling AI. These new iPhones are sure to give you the best AI performance of any smartphone.
Variable aperture (on the iPhone 18 Pro Max). Every year, Apple finds some way to improve the iPhone’s cameras. A year ago, in the iPhone 17 Pro, Apple kept the iPhone’s main lens (the 48MP Fusion Main) the same, but Apple improved the Ultra Wide lens and the Telephoto lens (with up to 8x zoom). This year, the other two lenses stay the same, and the main lens now supports variable aperture.
Aperture is simply the hole in a lens through which light passes to enter a camera. A smaller aperture lets less light reach the camera sensor, which is better in bright light. In low light, you want a wider aperture to capture more light. We all know how this works because we have seen our own eyes do it; in low light, our pupils expand to let in more light.
The aperture size in a camera is called an F-stop number. Technically, it is the ratio of the lens focal length (“f”) to the diameter of the pupil. Examples of F-stops are f/2.8, f/4, f/5.6, f/8, and f/11. Becuase it is a fraction, a smaller F-stop number means a larger aperture, so more light comes in. Think of it as the difference between 1/2 and 1/4. One-half of an apple is twice as much as one-fourth of an apple; similarly, f/2.8 lets in more light than f/4, so f/2.8 is a larger aperture than f/4.
Because changing aperture alters an image’s exposure, it can make images brighter or darker. Aperture also matters because it controls depth of field. With a narrow depth of field, background elements look blurry, and only the foreground stays in focus—an effect called bokeh that we associate with professional photography. With a wide depth of field, everything stays in focus, which is great for landscape photography.
Until now, every iPhone had a fixed focal length. From the iPhone 14 Pro through last year’s iPhone 17 Pro, the main camera uses a fixed ƒ/1.78 aperture. This year, the iPhone 18 Pro Max—and only the Max model, not the smaller version—includes a mechanism that can make the main camera aperture smaller or larger. Apple says that this corresponds to f/1.48, f/1.8, f/2.8, and f/4.0. Apple also says: “Combined with a new sensor that improves image quality, the result is better low-light photography, crisper detail in the back of group photos, and more unique shots.”
For most users, who just let their iPhone handle taking a picture, the result should be much better photos. For advanced users who want to manually adjust the aperture settings, they will have even more options for creating the perfect picture.
Apple Reference Image. As a lawyer, I often focus on the evidence to establish proof of what happened. But what is evidence in a world where anyone can use AI to very convincingly alter a photograph, changing the light from green to red? To address this, Apple is adding a feature called Apple Reference Image to the iPhone 18 Pro and 18 Pro Max. When you take a picture with the Main camera, the iPhone can “sign” every pixel that it captures. You can view reference images in the Photos app alongside the main image, and the reference image serves as a digital negative. Anyone can compare the reference image with another image to see what changed.
This is just a first step, but it is an important first step towards better tools for image authenticity. I wonder how long it will be before the first photography expert witness explains the concept of an Apple Reference Image to a judge or jury.
Smaller Dynamic Island. I love the useful information that Apple displays in the Dynamic Island area of an iPhone. Until now, the Dynamic Island could show information from either one or two apps. On the iPhone 18 Pro and Pro Max, the Dynamic Island has a smaller footprint and can display up to three simultaneous Live Activities. This sounds very useful.
Battery life. Battery life seems to improve almost every year with the iPhone. Last year, Apple said that the iPhone 17 Pro and Pro Max could play video for up to 33 and 39 hours. This year’s iPhone 18 Pro and Pro Max can play video for up to 36 and 45 hours.
Colors. I prefer using a black iPhone, but that wasn’t an option last year for the iPhone 17 Pro Max. This year, the color options are Burgundy, Glacier, Silver, and Black (yeah!). I prefer black because I want my iPhone’s hardware to fade into the background; my focus is on the screen. But since so many people loved last year’s Cosmic Orange, I know others disagree with me, and I hope they find a new color they like.
Etc. The new iPhone features a “next-generation vapor chamber” to keep the device cooler even when the processor is working hard. Instead of a Qualcomm modem, the 18 Pro Max uses Apple’s own C2 modem. Apple says that the C2 is much better than its previous C1X modem, but we’ll have to see how it compares to the tried-and-true Qualcomm modem. The 18 Pro (non-Max) still uses a Qualcomm modem.
Price. With technology getting more expensive because of the RAM shortages, I thought this year’s iPhone would cost $200 more. Instead, it is $100 more expensive than last year. The iPhone 18 Pro starts at $1,199, and the iPhone 18 Pro Max starts at $1,299.
The iPhone Duo
Apple’s long-anticipated folding iPhone is now here. I originally thought it would look like a normal iPhone when closed and like two side-by-side iPhones when opened. But as Ternus explained yesterday, that aspect ratio would be awkward for photos and videos. So instead, the iPhone is short and fat when closed, with dimensions similar to a passport (4.64" high, 3.31" wide). That means when it opens, the aspect ratio is similar to an iPad, just smaller (4.64" x 6.48"). This approach makes much more sense.

The hardware is intriguing. When closed, the 5.4" display delivers 90% of the screen area of an iPhone 18 Pro. But because it is short and wide, Apple moved the dock to the right side in a vertical orientation—a first for an iPhone—and put the status icons there, too.

When open, the 7.6" display approaches the size of the 8.3" display of the iPad mini. When opened, this is also the thinnest iPhone ever at just 5.2 mm. (The iPhone Air used to be the thinnest iPhone ever, but it is 5.64 mm.)

The only orientations that I expected were open and closed, portrait and landscape. But there is more. You can fold it partially to make it look like a tent, which puts the iPhone into StandBy mode and can also be used as an alarm clock.


You can also have it folded open like a book, making it easy to stand on a table. Apple also notes that this is a perfect, stable position for taking time-lapse photography. Or, it holds the iPhone stable so that you can be part of a group photo.

When the iPhone Duo is open, you can use it as a single large display, or you can run two apps side-by-side. Unlike an iPad, you cannot change the size of an app; it is either one-half of the screen or all of the screen. But you can pair two apps side-by-side, making it easy to switch between those two apps and another app (or another two apps).

The iPhone Duo will support the USB-C model of the Apple Pencil (although not until later this year).
When opened, there are screens on both sides of the device. Normally, the screen on the back of the device is black, but when you are taking a picture, you can have the back screen show another person what they look like, helping a person to pose in the picture. Better yet, if you are taking a picture of a child and trying to get the child to look at the camera, the back of the iPhone Duo can show an animated Snoopy cartoon, sure to get the child’s attention. Very clever.

There is a lot to be excited about here because it is so new. But I don’t think that this is the right iPhone for me, and it might not be for you, either. The iPad mini is a delightful device, but running apps made for a full-size iPad is sometimes frustrating because everything is too small. The iPhone Duo screen is even smaller. Will apps feel like iPhone apps with even more room to expand, or will they feel like iPad apps that are too small to use? I’m not sure.
Everything should be fast enough. The iPhone Duo uses the same A20 Pro chip as this year’s other new ihones.
The iPhone Duo is also missing some features on other iPhones. There is no Face ID, only a side button with Touch ID. There is no telephoto lens. There is a Main lens and an Ultra Wide lens, but they are not the more advanced versions used in the iPhone 17 Pro and iPhone 18 Pro (and certainly don’t have the variable aperture of the iPhone 18 Pro Max). When taking a selfie, the camera is undneath the screen. That’s neat, but we’ll have to see if it has an impact on quality. There is a Camera Control button, but there is no Action button.
With the iPhone Duo, you get some amazing new features. You also get a lot of compromises. And one of those compromises is price, with a starting price of $1999. That’s cheaper than I had expected, but it is still the most expensive iPhone ever.
Conclusion
The iPhone 18 Pro and Pro Max will be availble for pre-order this Saturday at 8am Eastern, and will be shipping on Friday, September 18. You cannot pre-order an iPhone Duo until October 16, and it ships on October 23.
I don’t expect Apple to sell nearly as many iPhone Duo models as it does other iPhones. But you cannot deny that this is a fascinating device, and I am thrilled to see Apple trying something new. For some, the iPhone Duo to be the perfect jack-of-all-trades.
If you just want a traditional iPhone that is better, the iPhone 18 Pro line is ready for our AI future thanks to its beefy processor, and the iPhone 18 Pro Max is sure to be the best iPhone camera ever. Plus, with other interesting features such as Apple Reference Image and the improved Dynamic Island, there is a lot to love in these new models.
Folks looking for a less expensive, more entry level, iPhone will have to wait. I presume that Apple will eventually release an iPhone 18 (without the “Pro”), but perhaps not until early 2027.
