Exploring the iPhone 18 Series: Release Date, Pricing, and Specifications

The iPhone 18 series is expected to debut in September 2026, with high-end models launching first, followed by more affordable options in Spring 2027. The base iPhone 18, iPhone 18 Pro, and Pro Max seem assured, while the foldable iPhone and Air 2 are also likely to launch.

Apple’s priority has been to eliminate the appearance of a crease on the screen when the phone is unfolded. The Fold’s inner screen is a Samsung design, but the hinge, panel structure, and lamination method are all Apple.

The latest supply chain rumours suggest that the design of the foldable model has been finalised and has been undergoing engineering tests ahead of mass production. The iPhone 18 series is expected to feature improved LTPO OLED panels, higher peak brightness, and a smoother 120Hz refresh rate.

The Pro models could feature an even smoother 120Hz refresh rate and more energy-efficient LTPO OLED panels, according to supply chain rumours. The iPhone 18’s screen brightness will increase from the iPhone 17’s 1000 nits of typical maximum brightness up to 1600 nits in HDR, with a peak brightness of 3000 nits.

Apple is expected to boost the RAM of the iPhone 18 base model to 12GB, bringing it in line with the high-end models and allowing it to run AI models on the phone itself, without resorting to the cloud. The iPhone 18 series will likely run on Apple’s upcoming A20 chip, with Pro models possibly running on an A20 Pro variant.

The iPhone 18 Pro models are rumoured to introduce variable aperture technology to the 48Mp main camera, allowing users to control how much light enters the lens and enabling superior control over depth of field and enhancing low-light photography.

The iPhone 18 series is expected to run on iOS 27, offering new features and capabilities tailored to the hardware. Apple typically introduces innovations in usability, security, and AI with every new iOS version, and we can expect the iPhone 18 series to showcase these improvements.
