Apple debuts iPhone 18 Pro and iPhone 18 Pro Max with variable aperture camera

Apple’s new iPhone 18 Pro and iPhone 18 Pro Max are taking aim at the parts of a phone people actually notice: the camera, battery, speed and the amount of time the device can survive being asked to do everything at once.

The Pro lineup introduces variable aperture on the main camera, a new A20 Pro chip, a redesigned Dynamic Island and Apple Reference Image, a system intended to help users verify the authenticity of photographs. Pre-orders begin on 12 September, with availability from 18 September.

Variable aperture finally arrives on iPhone

The new 48MP Fusion Main camera uses six laser-cut blades to move between apertures. Apple says the system can automatically adjust for lighting and depth of field, while giving photographers four manual aperture settings in the Camera app. That should make it easier to keep more people in focus, gather more light in darker scenes or deliberately blur the background.

Apple is also adding new Pro controls for shutter speed, white balance, aperture and exposure monitoring through a histogram. Photographic Styles gain texture and grain controls, while video gets post-capture Cinematic effects, 4K Dolby Vision time-lapse and updated Audio Mix tools. These are Apple’s feature claims and will need hands-on testing before they become proof of a better camera.

A phone that wants to prove its photos are real

Apple Reference Image is one of the more unusual additions. In Reference mode, the camera captures signed sensor data that Private Cloud Compute turns into an unalterable reference image. Users can view it alongside the regular photograph in Photos to compare whether edits have been made.

Apple says image metadata and upcoming SynthID support can also help identify images generated or edited with AI. That does not magically make digital images truthful, but it gives journalists, photographers and ordinary users another piece of evidence when the internet is increasingly full of images that look convincing and mean absolutely nothing.

A20 Pro and battery gains

A20 Pro is built using a 2-nanometre process and has 50 per cent more memory bandwidth than A19 Pro, according to Apple. The six-core CPU, seven-core GPU and dual 16-core Neural Engine are designed to improve sustained performance, graphics and on-device AI. Apple also says the redesigned vapor chamber enables up to a 40 per cent gain in sustained performance over the previous generation.

Battery life gets an equally confident headline. Apple says eSIM-only iPhone 18 Pro models offer up to 36 hours of video playback, while iPhone 18 Pro Max reaches up to 45 hours. The larger model can reportedly provide up to seven hours of video playback after five minutes of wired charging. Those are manufacturer figures measured under Apple’s conditions, not a guarantee of real-world screen time.

Siri AI and a more useful Dynamic Island

The redesigned Dynamic Island can show up to three Live Activities at once while retaining Face ID. Both models run iOS 27 and include Siri AI in beta, with Apple promising more personal context, onscreen awareness and the ability to act across messages, email, photos and other information.

The phones come in black, silver, glacier and new burgundy finishes. Apple says the launch will include Wi-Fi 7, Bluetooth 6, Thread and the C2 cellular modem system, with the US models adding mmWave support.

Our opinion

The variable aperture and Reference Image features are the genuinely interesting bits here. One gives photographers control Apple has avoided for years; the other acknowledges that proving an image’s history is becoming as important as taking it. But Apple still has not made a phone immune to marketing claims, and the real verdict will depend on price, testing and whether Siri AI is genuinely useful rather than merely present in the spec sheet.
