Apple unveils iPhone 18 Pro and iPhone 18 Pro Max with variable-aperture 48MP camera, bigger batteries, A20 Pro chip

What Apple announced

Apple introduced iPhone 18 Pro and iPhone 18 Pro Max as its newest pro-tier iPhones. The announcement centers on camera capability, battery life, sustained performance, and deeper on-device intelligence via iOS 27 with Apple Intelligence and Siri AI. Pre-orders start September 12 and devices arrive September 18.

Camera: variable aperture and computational upgrades

The headline camera change is a new 48MP Fusion Main camera that introduces variable aperture to iPhone for the first time. The mechanical system uses six laser-cut blades to transition between aperture settings. That lets the phone automatically adapt depth of field and exposure to scene conditions and also allows manual selection of any of the four aperture settings in the Camera app.

Developers get an API to control aperture across its range, and iOS, iPadOS, and macOS APIs expose new capabilities related to the camera's signed sensor output.

Video and audio improvements

Video gains include the ability to apply Cinematic effects after capture on clips shot up to 60 fps. Time-lapse can now record in 4K and Dolby Vision HDR. Audio Mix receives new algorithms aimed at delivering higher-quality voices and improved music isolation.

Performance, thermal, battery and display changes

Island has been redesigned to be smaller and described as "more useful," allowing expanded multitasking of live events in the area.

Software and features

iPhone 18 Pro models ship with iOS 27, which integrates Apple Intelligence and Siri AI to deliver on-device AI capabilities with user context while maintaining privacy and security. The announcement also notes APIs for developers to work with the camera's new features, and compatibility across Apple platforms.

Availability and finishes

Practical takeaways

• If you prioritize camera control, the variable aperture and Pro controls change how the iPhone can be used for creative and professional work.
• Image feature aims to provide a verifiable, unalterable sensor-backed asset for authenticity-sensitive workflows.
• Buyers who need longer battery life and sustained performance should look to the 18 Pro Max, which Apple highlights for its largest battery-life improvement.
