Apple’s new iPhone 15 Pro gets new chips, better cameras, and a titanium frame

Details about the iPhone 15 Pro and iPhone 15 Pro Max were revealed in a live broadcast from Apple today, and we’re looking at a mostly modest update—apart from the long-awaited switch to USB-C.

The iPhone 15 Pro and Pro Max will go up for pre-order on Friday, September 15th. Both will be available on September 22. The 15 Pro starts at $999 for 128GB, the same starting price as the iPhone 14 Pro for last year. The Pro Max technically gets a price hike, but only because Apple has axed the 128GB version—a 256GB iPhone 15 Pro Max starts at $1,199, the same price as the 256GB model from last year.

The most noticeable change is a shift from a stainless steel frame to one made out of a brushed “grade 5 titanium,” which Apple says makes the phone more durable while also making it lighter. The phone is also a little smaller than past models, thanks to slimmer display bezels. The screen sizes stay the same—6.1 inches for the base model and 6.7 inches for the larger iPhone 15 Pro Max one. Apple didn’t announce any changes to the phones’ actual screens, so expect the same resolution, ProMotion refresh rate, and brightness as before.

The iPhone 15 Pro comes in four colors.

Also new is an Apple Watch-esque “action button” that replaces the iPhone’s traditional mute switch. By default, it still serves as a mute switch, but users can change it to launch apps or the camera, or even to launch custom Shortcuts workflows.

The chips in Apple’s Pro phones also remain a generation ahead of the non-Pro phones. The A17 Pro is Apple’s first chip built on TSMC’s 3nm manufacturing process, which allows Apple to cram 19 billion transistors into a phone-sized SoC (up from 16 billion for A16 Bionic) continues to use two large high-performance cores and four high-efficiency cores; Apple says the performance cores are 10 percent faster than they were before, a relatively mild improvement, while the efficiency cores are more efficient rather than being faster.

The iPhone 15 Pro's A17 Pro has a slightly faster CPU, but its faster Neural Engine, ray-tracing-capable GPU, and USB 3 controller may be of more interest to pro users.

The A17 Pro’s six-core GPU is 20 percent faster than the A16 Bionic, a slightly more significant update; Apple has also added hardware-accelerate ray-tracing to the A17’s GPU, a feature also supported by newer Nvidia GeForce, AMD Radeon, and Intel Arc dedicated GPUs. The chip also includes hardware acceleration for the AV1 video codec, a royalty-free alternative to H.265/HEVC video codecs that is becoming more popular on streaming services like YouTube.

Apple has also added a new USB controller to power that USB-C port, allowing the iPhone to use 10 Gbps USB 3 transfer speeds for the first time (technically, this would make it either a USB 3.1 gen 2 or 3.2 gen 2 controller, if you can keep the USB-IF’s naming straight). Most people don’t use their iPhones for high-speed file transfers, but this will be a welcome update for people who use their phones to shoot gobs of high-resolution 4K video and want to transfer it to their desktops or laptops for editing.

Apple is also keeping the Pro’s camera system a step ahead of the standard iPhone. Apple says the Pro’s 48 megapixel main sensor is larger than the one in the regular iPhone 15. Like the iPhone 15, by default it will shrink the finished product down to 24 MP to save storage space, but if you’re shooting in ProRAW mode you can get the full 48MP image for cropping and editing. The camera defaults to a 24mm focal length, but 28mm and 35mm options are also made possible by the large sensor, and you can set any of the three focal lengths as your default.

The three-lens camera system on the iPhone 15 Pro allows a wide range of focal lengths without using digital zoom.

The telephoto lens is one point of differentiation between the Pro and Pro Max; in the iPhone 15 Pro, this continues to be a 3x telephoto lens with a 77mm focal length, similar to older models. In the larger Pro Max, the extra space allows Apple to step up to a 5x telephoto lens at a 120mm focal length. The 12MP ultra-wide camera lens gets a new coating and a macro shooting mode, but otherwise it isn’t changing much. Collectively, Apple says that the three lenses can shoot in macro, 13mm, 24mm, 28mm, 35mm, 48mm, and 77/120mm modes without using digital zoom.

The camera system is also looking ahead to the launch of the Vision Pro headset—Apple says that after an iOS update “later this year,” the phone will be able to shoot spatial video that can be viewed in three dimensions in a Vision Pro headset.

The iPhone 15 Pro starts at $999 (128GB), and the iPhone 15 Pro Max starts at $1,199 (256GB), which Apple claims is the same price for last year’s models at launch with similar storage configurations. The iOS 17 devices are available on September 22, with preorders starting this Friday. Apple also launched new case options for the iPhone 15 series, including a new FineWoven material that replaces leather as a more sustainable option for the iPhone 15 Pro and 15 Pro Max.
