Every year since 2007, Apple has debuted a new flagship iPhone. Other than the just plain “iPhone” original, they all have numbers of some sort in their name. If you make a list of them in order, it’s a bit of a marketing curiosity that the only one of the bunch whose number in its name corresponds to its generation number is the iPhone 4, which was in fact the fourth iPhone. (The “ten” in iPhone X marked 10 years, but it was the 11th flagship model.)
The iPhone 18 Pro, in fact, heralds Apple’s 20th iPhone generation:
Flagship Year Milestones 1. iPhone 2007 Holy shit 2. iPhone 3G 2008 3. iPhone 3GS1 2009 Speed 4. iPhone 4 2010 Retina 5. iPhone 4S 2011 Late spring → early fall release 6. iPhone 5 2012 Lightning, 3.5″ → 4″ 7. iPhone 5S 2013 Touch ID, 64-bit 8. iPhone 6 2014 Plus-size option 9. iPhone 6S 2015 10. iPhone 7 2016 2nd camera (Plus only) 11. iPhone X 2017 Holy shit redux 12. iPhone XS 2018 13. iPhone 11 Pro 2019 3rd camera 14. iPhone 12 Pro 2020 15. iPhone 13 Pro 2021 16. iPhone 14 Pro 2022 17. iPhone 15 Pro 2023 Pro video, USB-C, Action button 18. iPhone 16 Pro 2024 Camera Control button 19. iPhone 17 Pro 2025 Camera plateau expands, Ceramic Shield 2 20. iPhone 18 Pro 2026I compiled this list from memory. I had to double-check a few of the milestone notes, but I literally remember every single new flagship iPhone. And I don’t really have a particularly good memory. The fact that Apple has just incremented integers annually since the iPhone 11 makes that easier. But the iPhone is unique in this way. I can sort of do it off the top of my head with the major Apple II models: II, II Plus, IIe, IIc, IIGS.2 But I can’t do it with iPads, and I don’t think there’s even a way to make such a list for Macs.
Maybe next year Apple will commemorate the 20th anniversary with an iPhone 20 (there’s no way they’re going to call it “XX”, right? Right?). They skipped right over 9, and could do the same with 19. But the iPhone 18 Pro and Pro Max are the 20th new flagship models. That’s something.
But ... is the 18 Pro even the flagship iPhone of this generation? Apple first started launching multiple phones the same year with the “unapologetically plastic” 5C alongside the 5S. Starting with the simultaneous unveiling of the forgettable iPhone 8/8 Plus and unforgettable iPhone X in 2017, Apple has launched multiple models at different tiers each fall. But it’s always been obviously clear which iPhone was the iPhone.
This year, it’s not quite so obvious. Apple made no mention of the plain no-adjective iPhone 18 last week, and, now that I think about it, no one in the media wondered where it was. Apple never said “It’s coming early next year” and no one asked. Nor did Apple mention the year-old iPhone Air or offer even a hint that a sequel is coming alongside the 18 and 18e in early 2027.
But the 18 Pro debuted alongside the iPhone Duo. The Duo got the anchor spot in the announcement keynote. The Duo is getting the billboards. It was a pearl white Duo that John Ternus pulled from his tuxedo jacket on the red carpet at the Emmys Monday night. If it had been a burgundy iPhone 18 Pro instead, would the reporter from Deadline have screamed? Would it make a difference if someone told her the 18 Pro main camera now has variable aperture?
I do think the iPhone 18 Pro and Pro Max are the flagship iPhones this year. But I wonder if I’m biased from habit. The Duo makes this year different, unlike any other, because clearly it is the most exciting new iPhone. One week out and it feels like the most exciting new iPhone since the iPhone X nine years ago. A decade from now, if I make a list like the above with 30 years of “flagship” iPhones, might not the Duo occupy the 2026 spot?
Reply hazy, try again.
An ‘S’ by Any Other Name Would Smell as SweetApple hasn’t put an “S” in an iPhone’s name since the XS in 2018, but the 18 Pro is a very S-like phone. The S models all had similar attributes: they looked nearly identical to their year-prior predecessors, and their improvements were often internal or technical. The 3GS was remarkably faster than the 3G. The 5S added 64-bit support years ahead of when observers expected mobile ARM chips to do so, and introduced Touch ID. The S years tend not to be exciting but they are workmanlike. Apple’s rigorous annual update schedule for the iPhone as a whole, and Apple Silicon A-series chips specifically, leads to compounding gains. I’ll leave it to others to benchmark the A20 Pro chip rigorously, but some quick poking around suggests that the A20 Pro is about 1.2× faster than last year’s A19 Pro for single-core CPU. And the A17 Pro was about 1.2× faster than the A16 Pro.
Year over year, that’s nice, but it’s not game-changing. But these performance gains compound. 20 percent faster, give or take, every year, and after a few years the improvement is breathtaking. And most people only upgrade their phones every few years.
But, looking back at that list of 20 years of flagship iPhones, there’s a stark difference between the first ten and the second ten. In the iPhone’s first decade, genuinely radical changes appeared every two or three years. In the second decade, there haven’t been any radical changes from year to year at all. That’s not a slag on Apple’s design chops or an accusation of apathy or laziness. It’s just the nature of a design that Apple steered toward its platonic ideal. The general form of a MacBook Pro hasn’t changed much since the Titanium G4 PowerBook in 2002 — which came right around a decade after Apple invented the modern laptop with the PowerBook 100 series.
Let’s make a list of Hall of Fame iPhone models. I’ll arbitrarily cap it at five. Pick five iPhones for the Hall of Fame (or just up to five if you want to be stingy). Here’s my list:
- iPhone (original)
- iPhone 4
- iPhone 5S
- iPhone X
- iPhone 17 Pro
Perhaps it’s recency bias that has me putting last year’s 17 Pro on that list. But surely some iPhone in the post-X era qualifies for the Hall of Fame. I think it’s the 17 Pro. There was a long stretch of iPhones in the last 10 years where the entire back of the phone was glass. This glass cracked, a lot. I’ve only cracked the display glass of an iPhone twice in 20 years of carrying them. I’ve cracked the back glass on a bunch of them in the last five or six years. The iPhone 17 Pro fixed this, by going to a unibody aluminum frame, reducing the glass on the back to a panel. This looks better, feels better, and is seemingly far sturdier. The full-width camera plateau is more obtrusive, obviously, than the square corner plateau of previous iPhone Pro generations, but it’s more honest — both optically and physically more balanced. The camera system is such a prominent feature of these devices that it deserves a prominent protuberance. It’s very obvious to me that this is the best hardware design of the post-X era.
The iPhone 18 Pro and Pro Max are nearly identical to the 17 Pro and Pro Max in size and shape. Per Apple’s own specs, they’re precisely the same width, height, and thickness. In my personal testing, 17 Pro cases fit 18 Pro phones perfectly, as do 18 Pro cases (included from Apple in my review unit kit) on 17 Pro phones. I asked Apple if they’re stating that 18 Pro models are case-compatible with the iPhone 17 Pro, and they are not, because the 18 Pro camera plateaus are slightly thicker this year. I measured with a digital caliper and the difference is one-tenth of a millimeter: 11.5mm vs. 11.4mm. So Apple has raised the plateau guard lip on its own 18 Pro cases by one-tenth of a millimeter. I say that’s close enough to declare that you can use 17 Pro cases on 18 Pro iPhones and vice-versa.
But zooming back in time, I just happen to have an iPhone 13 Pro next to my desk. And in broad strokes, I can’t say that the iPhone 18 Pro form factor is all that different. I do think the 18 Pro form factor is better in every single way. Just as objects in hand, there’s not one aspect I prefer about the 13 Pro to the 18 Pro. I’m glad Apple moved away from sharp corners, polished metal sides (slippery) and all-glass backs (my 13 Pro is cracked in the corner); expanded the camera plateau; and replaced the mute switch with the Action button and added the Camera Control button. But overall, these two phones, five years apart, are fundamentally similar. Familiarity may not breed contempt in this case, but it does breed boredom.
The iPhone Duo is not boring.
The iPhone 18 Pro, let’s just say it, sort of is. But it’s boring because it’s exactly like the iPhone 17 Pro — except for specific details inside the phone that are obviously better:
Variable aperture on the main 1× camera lens. Most users will never adjust this manually but the Camera app will use it automatically, and results will be better. Even if you don’t know squat about photography it’s rather intuitive what aperture does, just knowing that it involves an iris-like mechanism. Open wide, it lets in more light (useful in low lighting); closed up, it lets in less light (useful in bright light). Open apertures decrease depth of focus; closed apertures increase depth of focus. Those facts can be used to artistic effect. In manual control, the iPhone 18 Pro 1× camera offers four stops for aperture: ƒ/1.48, ƒ/1.8, ƒ/2.8, and ƒ/4.0. This is a genuine hardware breakthrough. Over the next five years or so, I expect variable aperture to expand to the telephoto and ultrawide lenses. I’m not saying iPhone camera hardware won’t continue to improve after that — I’m sure it will — but I suspect variable aperture is the last remaining “easy win”. I think every camera gain after this will be more incremental.
A20 Pro chip. It’s noticeably faster and more efficient. Not radically faster and more efficient. Just noticeably. This is how Apple rolls.
Redesigned thermal system with a much larger vapor chamber. It’s much easier to report on peak performance with benchmarks than it is to assign a score to sustained performance, but sustained performance is what matters most to users who really push their phones as computers. This could be playing games, shooting 4K ProRes video, or running local AI models. We all know the drill. You push your phone and it gets hot, and when it gets hot it slows down. An improved thermal system sounds so much like a pocket-protector-wearing nerd feature, but it really matters. I suspect that for sustained use cases, it would be more performant to have the 18 Pro’s new thermal system running the 17 Pro’s A19 Pro chip than to have the new A20 Pro chip running with the 17 Pro’s first-generation vapor chamber. But with the iPhone 18 Pro, you get both: you get the faster and more efficient A20 Pro chip and the second-generation vapor chamber thermal system. This is how Apple rolls.
C2 cellular modem. The one and only odd spec regarding the iPhone 18 Pro lineup is that they use Apple’s own C2 cellular modem in all models worldwide but with one exception: 18 Pro Max models sold in the United States. The regular-size iPhone 18 Pro in the U.S. gets the C2, and all 18 Pros — regular and Max — outside the U.S. get the C2. Apple isn’t explaining this oddity but I think Joe Rossignol at MacRumors deduced correctly: it’s for minimal compliance with their 2023 contract with Qualcomm, which Qualcomm promoted as covering “smartphone launches in 2024, 2025 and 2026.” I’ve spent time over the last week with both the 18 Pro and Pro Max and didn’t notice one whit of difference network-performance-wise. And there’s no easy way to measure the effect the modem has on battery life. But we know Apple’s C-series modems are noticeably more power-efficient than Qualcomm’s. If Apple had to use a Qualcomm modem in one model, in one region, it makes sense that it would be the 18 Pro Max in America. All Pro Max variants have larger batteries than the regular-size models, and the U.S. 18 Pro Max model has the very biggest battery of them all, because U.S. iPhones no longer have SIM card trays. Thus the 18 Pro Max is taking one for the team, while still delivering better battery life than last year’s 17 Pro Max. The U.S. iPhone 18 Pro Max will almost certainly be the last product Apple ever ships with a Qualcomm modem. Good riddance.
Photographic Styles 3 and pro controls in the Camera app. I’ll mostly leave it to better photographers than me to evaluate the iPhone 18 Pro camera system and its exclusive Camera app features in detail. But I’ll say this, before getting to a few example photos below: it’s worth separately considering the iPhone camera hardware from the iOS Camera app software. For my own personal photography, I’ve switched away from Apple’s Camera app to a mix of third-party camera apps: Halide, Not Boring Camera, and Analogue. That’s a discussion for another time, but the basic reason is that I strongly prefer a more film-like look that embraces the nature of the iPhone’s small image sensors with grain, to Apple’s overly processed digital look that compensates for the noisy small sensors by applying computational smoothing. I’m far from alone in having grown tired of the smooth over-processed look, and the optional new “Film” texture look in the Camera app — exclusive to the A20 Pro-powered iPhones 18 Pro and Duo, thus far — is a move in that direction. This makes photography using Apple’s own Camera app far more appealing to me. But the variable aperture in the main camera makes the iPhone 18 Pro camera system better for all camera apps. And if you don’t like the new film texture and optional grain from Apple’s own Camera app, it’s optional (and, unsurprisingly, off by default — by default the Camera app takes photos that look like what people expect iPhone photos to look like).
The 18 Pro is the third generation with the Camera Control button. But that button hasn’t changed at all since the 16 Pro, the phone on which it debuted. At some point in the last year, I gave up on using the Camera Control button as anything other than a simple button. I went into Settings and turned off all the features where you can soft-press it and slide your finger back and forth to adjust camera features while using Apple’s Camera app. What I found is that I kept changing things inadvertently and undesirably. It’s too prone to accidental half-presses that put it into slide-to-adjust for some setting, and because it’s an accident, my finger would start changing things. I turned that all off and I’m much happier for it. Now I just use the Camera Control button for four things:
A full click of the button to jump me into the camera app of my choice. It doesn’t matter if the phone is locked, or if I’m using it for something else at the moment. I click this button and boom, I’m ready to snap a photo.
Click-and-hold the button to launch the Camera app in Siri mode, for Visual Intelligence. I don’t use this often but that’s less a statement about its usefulness than it is about the fact that I just haven’t yet developed the habit of pointing my camera at something to ask Siri about it. It’s really quite useful with Siri AI in iOS 27, and even if you only use it occasionally, there’s no reason not to assign it to a long press of the button. That said, I don’t think this feature belongs in the Camera app. It ought to be a tab in the Siri app. The Camera app should be for photography; the Siri app ought to be for all things Siri, including Visual Intelligence.
While I’m in a camera app, I sometimes half-press the button for AE/AF Lock.
While I’m in a camera app, I sometimes use a full click of the button as the shutter. But most of the time, I still use the on-screen shutter button. The reason is something I complained about in my iPhone 16 Pro review two years ago:
At first, though, I was frustrated by the physical placement of Camera Control. As a hobbyist photographer who has been shooting with dedicated cameras all the way back to the late 1990s, my right index finger expects a shutter button to be located near the top right corner. But the center of Camera Control is 2 inches (5 cm) from the corner. I’ll never stop wishing for it to be closer to the corner, but after a week I’ve grown acclimated to its actual placement. And I get it. I’m old enough that I shoot all of my videos and most of my photos in widescreen orientation. But social media today is dominated by tallscreen video. As Apple’s Piyush Pratik explained during last week’s keynote, Camera Control is designed to be used in both wide (landscape) and tall (portrait) orientations. Moving it more toward the corner, where my finger wants it to be, would make it better for shooting widescreen, but would make it downright precarious to hold the iPhone while shooting tall. I hate to admit it but I think Apple got the placement right. Shooting tallscreen is just way too popular. And, after just a week, my index finger is getting more and more accustomed to its placement. It might prove to be a bit of a reach for people with small hands, though.
After two years, I still think Apple put the Camera Control where it was to make it useful to people who shoot video and take photos vertically. But, proud Gen-Xer that I am, I still shoot almost all my videos and photos horizontally, and this button is too far away from the corner to be a convenient shutter button while holding the phone horizontally. So I tend not to use it. I would use it as a shutter much more often if it were as close to the corner as the Action button is to the opposite corner. I’m a little bitter about this.
Photographic Styles 3, With Film Texture and GrainWhen shooting with Apple’s Camera app, iPhone 18 Pro introduces support for Apple’s Photographic Styles 3. As with previous generations of Photographic Styles, these styles are non-destructive. You can shoot photos without them and add Photographic Styles later, in Apple Photos. Or you can shoot with them, and adjust or remove them later. The non-destructive nature of Photographic Styles is essential to note. You can capture images in black-and-white, to name a conspicuous example, and go back to full color in post.
The first two generations of Photographic Styles adjust only color. Apple calls this “Palette”. Photographic Styles 3 adds Texture, with four options:
- Standard (no texture)
- Soft Skin
- Glow
- Film
The only one I’ve tried, both because I’ve only had the iPhones 18 Pro for one week and because it’s the only one that appeals to me, is Film. When you change a style to use the Film texture, there are two additional adjustments: the strength of the film-like texture (0–100), and an on/off toggle for “Grain”. Soft Skin and Glow also have 0–100 sliders to adjust the strength of those textures, but only Film has the option to add Grain. Soft Skin defaults to 88 strength, Glow defaults to 50, and Film defaults to 100. Grain is on by default when you switch to Film.
Grain, to my eyes, and based on my conversations with Apple folks who worked on it, is not a simplistic lessening of image sensor noise reduction. It’s a process that attempts to replicate actual f
