The iPhone 18 Pro Max is official, bringing Apple's first variable aperture camera, a new A20 Pro chip built on a 2nm process, and Apple's first fully in-house modem to the largest iPhone in the lineup. Here's everything Apple has confirmed, from pricing to release date to what's actually changed under the hood.
Apple broke from its usual single-event pattern this year. Rather than releasing the full iPhone 18 lineup together in September, the iPhone 18 Pro, iPhone 18 Pro Max, and Apple's first foldable iPhone, called iPhone Duo, headlined a September 9 event, while the standard iPhone 18, a new iPhone 18e, and a second-generation iPhone Air remain unannounced and are expected in spring 2027. The iPhone Duo is a separate device with its own pricing and an October release; this article focuses specifically on the iPhone 18 Pro Max.

Release Date and Availability
Apple announced the iPhone 18 Pro and iPhone 18 Pro Max at its "Surprise and Shine" event on September 9, 2026. Pre-orders opened September 12 at 5 a.m. Pacific Time, and both phones become available on Friday, September 18, 2026. That confirms what most reports had predicted, an announcement in the second week of September followed by availability about a week later.
As expected, the rest of the iPhone 18 lineup did not launch alongside the Pro models. The standard iPhone 18, a new budget iPhone 18e, and a second-generation iPhone Air remain unannounced, with reports still pointing to a spring 2027 launch. Apple's fall event instead centered on its three most expensive iPhones, the iPhone 18 Pro, iPhone 18 Pro Max, and the debut of iPhone Duo, Apple's first foldable iPhone, which arrives separately in October.
Design Changes
The iPhone 18 Pro Max keeps its familiar design language rather than a dramatic overhaul, including a triple-lens rear camera system on a similar camera plateau. The most significant change is a smaller Dynamic Island, made possible by moving more Face ID components under the display, one of the more meaningful changes to the iPhone's front design in several years.
The body size stays close to previous Pro Max models rather than getting noticeably thicker, at 8.8mm thick and 249 grams. The front and back are protected by Ceramic Shield 2, and the phone carries an IP68 rating. Apple confirmed four launch colors: burgundy, glacier, silver, and black, rather than the "Dark Cherry" name that had circulated in earlier color leaks.
A20 Pro Chip, RAM and the New Modem
The iPhone 18 Pro Max ships with Apple's new A20 Pro chip, built on an advanced 2nm manufacturing process, a genuine leap from the current 3-nanometer A19 Pro. A smaller process node generally means better performance per watt, and Apple has paired the chip with a redesigned vapor chamber thermal system to help sustain performance during heavier tasks like gaming or video editing. RAM lands at 12GB, at the higher end of what analysts had predicted, giving the phone more headroom specifically for on-device Apple Intelligence and Siri AI features.
The bigger surprise wasn't in the rumors at all: Apple has replaced Qualcomm's modem with its own in-house C2 modem across the iPhone 18 Pro lineup, marking the first time Apple has used a fully custom modem rather than a third-party chip. It's a significant supply chain shift that early coverage suggests improves power efficiency, though independent connectivity testing will take time to confirm how it holds up against Qualcomm's modems in daily use.
Camera Upgrades
The headline rumor turned out to be true: both the iPhone 18 Pro and Pro Max get a 48MP Fusion Main camera with a genuine variable aperture, the first time physical aperture control has come to an iPhone. A six-blade mechanical system smoothly adjusts between f/1.48 and f/4.0, either automatically based on lighting and desired depth of field, or manually through the updated Camera app, which now offers direct control over aperture, shutter speed, and white balance alongside a real-time histogram. Apple is also opening an API so third-party camera apps can access the full aperture range.
The rest of the camera system rounds out with a 48MP ultrawide lens optimized for macro shots and landscapes, and a 48MP periscope telephoto lens offering up to 5x optical zoom on the iPhone 18 Pro and up to 10x optical zoom on the larger Pro Max. The front-facing camera jumps to 24MP, up from 18MP, for sharper selfies and video calls. On the video side, cinematic effects can now be applied after capture to footage shot at up to 60fps, time-lapse mode supports 4K with Dolby Vision HDR, and a new Audio Mix feature improves voice capture and can isolate music from background noise.
Battery and Charging
Apple doesn't advertise battery capacity directly, but EU energy labels, which Apple is legally required to publish, confirm the iPhone 18 Pro Max's SIM-tray version carries a 5,391mAh battery, an 11.7% increase over the iPhone 17 Pro Max's 4,823mAh cell. The smaller iPhone 18 Pro comes in at 4,056mAh, only a modest bump over its predecessor, meaning nearly all of this generation's battery gains went to the Pro Max specifically. eSIM-only versions sold in markets like the US, which don't need space for a physical SIM tray, are expected to carry a slightly larger cell still, though Apple hasn't published that figure separately. Apple rates the Pro Max for up to 45 hours of video playback, up from 39 hours on the previous generation.
Charging also improved modestly: Apple says the iPhone 18 Pro Max can now reach 50% charge in around 15 minutes over a wired connection, down from roughly 20 minutes previously. Wireless charging remains capped at 25W through MagSafe and Qi2, so Apple still hasn't closed the wireless charging gap with faster-charging Android rivals.
iOS 27 and Apple Intelligence
The iPhone 18 Pro Max ships with iOS 27 out of the box, including Siri AI, Apple's redesigned conversational assistant. Getting the most out of Siri AI on day one comes with a few caveats worth knowing before you set up your new phone: access is currently gated behind a waitlist you join from Settings, Siri AI launches in English only with more languages expected in October, and it isn't available in the European Union or China yet.

Price and Storage
The iPhone 18 Pro Max starts at $1,299 for 256GB, a $100 increase over the iPhone 17 Pro Max's launch price, which Apple and industry analysts have both linked to the ongoing global RAM supply shortage affecting the wider phone industry. The smaller iPhone 18 Pro starts at $1,199, also a $100 increase over its predecessor. Storage options run from 256GB up to a new 2TB tier, priced at $1,599 for the Pro Max.
| Storage | iPhone 18 Pro Max Price |
|---|---|
| 256GB | $1,299 |
| 512GB | $1,449 |
| 1TB | Confirmed tier, pricing per carrier/retailer |
| 2TB | $1,599 |
If you don't need this year's specific upgrades, especially the variable aperture camera, the iPhone 17 Pro Max remains a strong flagship and is likely to see price cuts now that its successor has arrived. We'll publish our full hands-on review of the iPhone 18 Pro Max, including real camera samples and battery testing, once the phone ships on September 18.
