Apple (AAPL) stock slipped 0.76% to $313.82 on Wednesday as Apple introduced its latest premium iPhone models. The company launched iPhone 18 Pro and iPhone 18 Pro Max with major hardware and software upgrades. The release adds the A20 Pro chip, Siri AI, improved cameras, stronger battery life, and new thermal technology.
Apple Unveils iPhone 18 Pro With A20 Pro Performance
Apple introduced the iPhone 18 Pro lineup with the new A20 Pro processor built using two-nanometer technology. The chip provides 50% more memory bandwidth compared with the previous A19 Pro processor. Apple also equipped the chip with six CPU cores and a redesigned seven-core graphics processor.
The new graphics system delivers up to 40% faster performance compared with the previous generation. Meanwhile, Apple added a dual 16-core Neural Engine with 32 total cores for heavier computing workloads. The architecture also supports computational photography, advanced processing, gaming, and other demanding smartphone functions.
Apple redesigned the thermal system to support higher performance during extended use. A larger vapor chamber provides three times more surface area than the previous iPhone 17 Pro design. Consequently, the company says the new system can deliver sustained performance gains reaching 40% over its predecessor.
iPhone 18 Pro Adds Variable Aperture Camera and Longer Battery Life
Apple equipped both Pro models with a new 48-megapixel Fusion Main camera featuring variable aperture technology. Six adjustable blades allow the camera to control depth, lighting, and image detail more precisely. Users can also manually adjust aperture, shutter speed, white balance, and exposure settings inside the Camera application.
The camera system also introduces upgraded photographic controls and improved low-light performance. Additionally, users can apply cinematic effects after recording videos at speeds reaching 60 frames per second. Apple also added 4K Dolby Vision recording support for time-lapse videos and improved audio processing.
Battery performance received another major upgrade across both devices. The iPhone 18 Pro offers up to 36 hours of video playback on eSIM-only models. Meanwhile, the iPhone 18 Pro Max extends video playback to 45 hours under similar conditions.
Siri AI and iOS 27 Expand Apple’s Software Push
Apple will ship both Pro models with iOS 27 and the latest version of Siri AI. The system can use personal context from messages, emails, photographs, and onscreen content when handling user requests. Apple designed the software to perform many processing tasks directly on devices while supporting cloud-based processing when required.
The software also introduces new editing features for photographs and expanded tools across Apple’s applications. Safari includes a notification feature that tracks selected webpage changes, including product availability and price movements. Meanwhile, the redesigned Dynamic Island can display three Live Activities simultaneously while continuing to support Face ID.
Pre-orders for the iPhone 18 Pro lineup begin September 12, while general availability starts September 18. Apple will offer the devices in black, silver, glacier, and a newly introduced burgundy finish. The launch expands Apple’s premium smartphone lineup as the company pushes deeper into performance, photography, battery efficiency, and intelligent software.
