The iPhone 18 Pro's boldest moves are mechanical: blades on the camera, memory off the die

Apple's iPhone 18 Pro announcement was packed with numbers — 2nm, 40%, 32 cores — but the two most interesting things in it are physical. One is a camera aperture with six moving blades, a genuine first for an iPhone. The other is a memory chip that no longer sits on top of the hot silicon. Everything else, including the regional asterisks, follows from those two choices.

The Pro starts at $1,199 and the Pro Max at $1,299, with pre-orders on September 12 and availability on September 18. Apple's marketing chief Greg Joswiak set the tone: "With iPhone 18 Pro, we've made advancements to the areas our users care about most: camera, performance, battery, and intelligence. And we didn't just make incremental improvements in these areas, we took huge leaps forward to create the best Pro iPhone we've ever made."

The 48-megapixel Fusion Main camera now opens and closes its aperture mechanically. Per Apple's keynote, the system uses six laser-cut blades, each thinner than a human hair, made of a polymer composite, driven by a new rotor mechanism with a custom lens designed to hold image quality at multiple apertures. The Next Web's launch report puts the widest setting at ƒ/1.48 for low light, with four aperture stops selectable by hand. Apple says the camera adjusts automatically for depth of field and lighting, and an API exposes the full range to third-party camera apps.

Around it, Apple finally shipped the manual controls photographers have asked for: shutter speed, white balance and aperture in a Pro panel, plus a histogram, texture and grain controls in Photographic Styles, and Cinematic effects that can be applied after capture to video shot at up to 60fps.

The A20 Pro is Apple's first 2-nanometer phone chip. MacRumors' report from the event lists the claims: a 6-core CPU with two "super cores" Apple calls up to 20% faster, a 7-core GPU up to 40% faster, neural accelerators with twice the FP8 throughput, and a second Neural Engine that brings the total to 32 cores and double the AI compute, fed by 50% more memory bandwidth.

The engineering detail that matters more than any of those figures is packaging borrowed from Apple's M-series work: the memory has been moved out of the chip's thermal path and sits beside the die, attached directly to a vapor chamber with three times the surface area of the iPhone 17 Pro's. Apple's pitch is sustained, not peak, performance — 40% more than the A19 Pro and twice the A18 Pro under load.

The Next Web, which had called all four of the Pro's headline changes in August, offered the right yardstick for that claim: "Peak numbers are easy. Sustained numbers are what a phone actually delivers." A vapor chamber big enough to matter is easy to promise and easy to verify, and reviewers will verify it.

Buyers in the EU get the same hardware with two features switched off at launch. Siri AI, the rebuilt assistant, "will not be available initially in the EU on iOS, iPadOS, and watchOS," Apple says, adding it is "working hard to find a path forward that preserves its users' privacy and security" — with no reason and no date given. Apple Reference Image, the new system that signs sensor data at capture to create an unalterable companion to any edit, also cannot capture reference images in the EU at launch, and is absent entirely in China on regulatory grounds.

Elsewhere, Siri AI ships as a beta in English only, with five more languages in October; some server-side Apple Intelligence features carry daily usage limits, and expanded access "will be available for a fee in the future."

Battery splits by SIM. The quoted 36 and 45 hours of video playback on the Pro and Pro Max belong to eSIM-only models sold in 12 markets including the US, Canada, Japan and Mexico — Europe keeps the physical SIM tray and, per Apple's own math, a smaller battery worth about two fewer hours. Charging is 50% in around 15 minutes wired, or 30 wireless; five minutes of wired charging on the Pro Max buys roughly seven hours of video.

The iPhone 18 Pro is a hardware-led launch under a hardware-engineer CEO — a mechanical aperture, reworked thermals, a bigger battery. The open questions are equally concrete: whether the vapor chamber sustains that 40% claim, when Siri AI clears European regulators, and how much the promised intelligence will eventually cost.
