Introduction
The iPhone 18 represents Apple’s next major leap in smartphone design and technology. Expected to be announced in September 2026, the iPhone 18 series is rumoured to introduce under‑display Face ID on Pro models, solid‑state buttons, a new A18 Pro chip, and significant camera upgrades. This manual is based on industry leaks, analyst reports, and Apple’s historical patterns. It will be updated when official specifications are released. Use this guide to understand the expected features, setup process, and troubleshooting for the iPhone 18, iPhone 18 Plus, iPhone 18 Pro, and iPhone 18 Pro Max.
Product Overview
The iPhone 18 is expected to feature a 6.1‑inch display (standard model) and a 6.7‑inch display (Plus), while the Pro and Pro Max will likely use 6.3‑inch and 6.9‑inch panels, respectively. All models are expected to support a 120 Hz ProMotion display, though standard models may finally adopt this feature after years of being limited to 60 Hz. The design will likely retain the titanium frame on Pro models, with a new aluminium‑titanium hybrid for standard models. The most significant change is the removal of the Dynamic Island on Pro models in favour of an uninterrupted, edge‑to‑edge screen with under‑display Face ID. Solid‑state buttons with haptic feedback are expected to replace physical volume and power buttons on Pro models, while standard models may keep physical buttons for now.
The rear camera system on Pro models will include a 48 MP main sensor, a 48 MP ultra‑wide, and a telephoto lens with up to 6x optical zoom (Pro Max). Standard models are expected to feature a dual‑camera setup with a new 48 MP main and a 48 MP ultra‑wide. All models will support Apple Intelligence, introduced with iOS 18 and expanded with iOS 20. The battery is expected to use stacked cell technology, enabling larger capacity and faster charging, possibly up to 40 W wired. The Lightning port is already gone; all models will use USB‑C with USB 3.2 speeds.
