Reports ahead of Apple’s September event list several concrete hardware changes for the iPhone 18 Pro family — a new A20 Pro chip on a 2nm process, a variable-aperture main camera, a new C2 modem, tweaks to the camera island and rear design, and larger batteries.
A20 Pro chip may be Apple's first 2nm-process iPhone chipset, built by TSMC with Apple’s design.
Main camera is reported to gain variable aperture, enabling adjustable depth of field control.
Design changes include a slightly smaller camera island, rear tweaks, and larger batteries, with the Pro Max tipped to have Apple’s largest iPhone battery yet.
Apple's September event is expected to focus on the iPhone 18 Pro models. Multiple reports collected ahead of the launch point to a set of hardware upgrades that together could make the iPhone 18 Pro family a clearer generational step over the iPhone 17 Pro.
Processor: A20 Pro on a 2nm process
Sources indicate the iPhone 18 Pro could ship with an A20 Pro chip built on TSMC's 2nm process. The design itself would be Apple's work, while TSMC would supply the 2nm fabrication. If accurate, this would represent a first-time 2nm implementation in an iPhone chipset and would be presented as a major performance and efficiency improvement over previous nodes.
Camera: variable aperture on the main sensor
Design tweaks are part of the rumor mix. The camera island is said to be slightly smaller, which would be a modest visual change rather than a full redesign. The back of the phone may see other subtle alterations. On battery capacity, the iPhone 18 Pro Max is specifically tipped to pack Apple's largest battery yet for an iPhone, implying a focus on extending real-world battery life.
Camera Control and hardware features
Apple added a physical Camera Control on the side of recent iPhones. Reports suggest Apple intends to upgrade that control with the iPhone 18 Pro, though details on how it will change are not yet available.
Taken together, the reported A20 Pro 2nm chip, the variable-aperture main camera, a newer modem, and larger batteries point to meaningful hardware-focused upgrades. Buyers who prioritize processing headroom, camera flexibility, and battery life are the likely target audience for the Pro models if these specs are confirmed.
