Apple has announced the iPhone 18 Pro and iPhone 18 Pro Max, and the biggest changes sit inside the phone. According to Apple’s press release, both models move to a 2-nanometer A20 Pro chip and gain a smaller Dynamic Island. They also add a variable-aperture main camera. Pre-orders open Saturday, September 12, and the phones ship Friday, September 18.
Prices also climb. The iPhone 18 Pro starts at $1,199 with 256GB, while the iPhone 18 Pro Max starts at $1,299. That is $100 more than last year, when the iPhone 17 Pro started at $1,099. Apple revealed both phones at its September 9 event, alongside the foldable iPhone Duo.
A20 Pro and a bigger vapor chamber
The A20 Pro is Apple’s first 2-nanometer phone chip. For a start, Apple says the 6-core CPU includes integrated Neural Accelerators. In addition, the new 7-core GPU is up to 40 percent faster than the A19 Pro, and memory bandwidth rises by 50 percent. Meanwhile, a Dual 16-core Neural Engine with 32 cores in total doubles the AI processing power of last year’s chip.
Just as important, Apple changed how the chip is packaged. The A20 Pro sits side by side with its memory, an idea borrowed from the M-series Mac chips. Consequently, the memory leaves the thermal path, and the chip attaches directly to a next-generation vapor chamber. That chamber has three times the surface area of the iPhone 17 Pro’s. As a result, Apple claims up to 40 percent higher sustained performance.
Greg Joswiak, Apple’s senior vice president of Worldwide Marketing, called the changes more than a refresh. “We didn’t just make incremental improvements in these areas — we took huge leaps forward to create the best Pro iPhone we’ve ever made,” he said. Still, those are Apple’s numbers, so treat them as claims until independent benchmarks land.
A smaller Dynamic Island shows three Live Activities
The Dynamic Island shrinks this year, though it does not disappear. Apple says new display technology creates room for more information. As a result, the island can now show three Live Activities at once. Face ID still lives inside it for unlocking, payments and app sign-ins. In practice, it builds on iOS features such as the Live Activities Sonos recently brought back to the Lock Screen.
Apple has not published exact dimensions for the new cutout, so “smaller” remains a visual claim for now. However, the software side is concrete. For example, three simultaneous Live Activities will help people juggling deliveries, timers and live scores.
Variable aperture on the 48MP Fusion camera
The 48MP Fusion Main camera gets a mechanical variable aperture, a first for iPhone. Specifically, six laser-cut blades move between four aperture settings. In automatic mode, the camera picks an aperture for depth of field and lighting. Meanwhile, a new Pro controls layout in the Camera app adds manual aperture, shutter speed and white balance. An API also lets third-party camera apps drive the aperture.
The variable aperture only applies to the main camera. The telephoto and ultra-wide lenses keep fixed apertures, as Engadget’s report notes. Apple pairs the new lens with a new sensor and computational imaging pipeline. In turn, it promises better low-light shots and sharper faces at the back of group photos. Video gains too. Cinematic effects now apply after capture at up to 60 fps, and Time-lapse records in 4K Dolby Vision HDR.
Apple Reference Image signs every pixel
The new sensor can sign every pixel it captures. In Reference mode, Private Cloud Compute turns the signed sensor data into an unalterable reference image. That reference sits next to the main photo in the Photos app, like a digital negative. Therefore, anyone can compare the two and spot edits.
There are limits, however. Reference mode is opt-in, and capture is unavailable in the EU at launch. In China, it is unavailable at launch for regulatory reasons. Because verification runs through Apple’s cloud, users must also trust Apple as the notary. It is a useful step for photojournalists, but it is not universal proof of authenticity.
Battery, Siri AI and iOS 27
Apple calls this the largest battery-life increase ever on an iPhone. eSIM-only models reach up to 36 hours of video playback on the iPhone 18 Pro. Likewise, the Pro Max stretches to 45 hours. Wired charging hits 50 percent in about 15 minutes.
Both phones ship with iOS 27, which arrives as a free update on Monday, September 14. Siri AI launches the same day as a beta in English. French, Japanese, Korean, Portuguese and Spanish follow in October. We flagged several of these additions when Apple held back three iOS 27 features for the fall. Notably, Siri AI is not initially available in the EU.
Colors, storage and where to buy
The iPhone 18 Pro comes in black, silver, glacier and a new burgundy. Storage, meanwhile, runs from 256GB to 2TB. Pre-orders start at 5 a.m. PT on Saturday, September 12, in more than 65 countries, including the U.S. Availability begins Friday, September 18, and 20 more countries follow on September 25. Apple Trade In offers $175 to $885 for an iPhone 13 or newer, while carrier deals reach up to $1,200.
Engadget’s take is fair: the Pro models look almost identical to last year’s phones. Apple clearly wants the spotlight on the foldable iPhone Duo. Even so, the A20 Pro, the variable aperture and the battery gains give current Pro owners a real reason to upgrade. Ultimately, we will know how real the sustained-performance claim is once the phones arrive next week.
