iPhone 18 Pro: Everything the Latest Leaks Reveal

The iPhone 18 Pro and iPhone 18 Pro Max are shaping up to be one of the most significant — and most expensive — upgrades in Apple's history. Leaks and supply chain reports from across the industry paint a picture of a phone that breaks new ground in several ways at once: a first-ever chip shrink to 2nm, a mechanical variable aperture camera, a split launch timeline, and a price hike that Apple's own CEO has called unavoidable.

Here's a breakdown of everything the latest leaks reveal.

A First for Apple: The Split Launch

For the first time, Apple is rumored to be splitting the iPhone 18 lineup across two release windows. The iPhone 18 Pro and iPhone 18 Pro Max — along with the long-rumored foldable "iPhone Ultra" — are expected to be unveiled in the first half of September 2026 and go on sale in the second half of the month .

The standard iPhone 18, iPhone 18e, and iPhone Air 2 are reportedly delayed until spring 2027 . This staggered approach is a major strategic shift, likely designed to give the premium models a clear window without cannibalizing the more affordable variants.

A20 Pro Chip: Apple's First 2nm Processor in a Phone

The A20 Pro chip, built on TSMC's 2nm process (N2), is one of the most anticipated hardware changes. It will be Apple's first 2nm chip inside a phone, promising a roughly 15% faster CPU and up to 30% better power efficiency compared to the A19 generation . The chip is also expected to use Wafer-Level Multi-Chip Module (WMCM) packaging .

This efficiency gain is critical: it will power the phone's more demanding on-device AI features and the new Gemini-powered Siri, while also supporting the rumored larger battery without compromising battery life .

Mechanical Variable Aperture Camera

For the first time in iPhone history, the main 48-megapixel Fusion camera on both Pro models is expected to feature a mechanical variable aperture . Instead of a fixed f/1.78 lens, the aperture would be adjustable (reports suggest a range between f/1.4 and f/4.0), giving users real control over light intake, depth of field, and exposure .

Supplier component production is already underway, and the change marks a shift from computational to optical innovation as the headline camera upgrade . The new system may also be paired with a three-layer stacked Samsung image sensor, potentially replacing Sony for the main camera .

12GB RAM and Expanded Battery

Both Pro models are expected to jump to 12GB of RAM, up from 8GB in the iPhone 17 Pro . This is driven by the need to support on-device AI workloads. Battery capacity is also reportedly increasing significantly, with some leaks pointing to a potential ~5,000mAh battery in the Pro Max (up from about 4,685mAh in the iPhone 17 Pro Max) .

Smaller Dynamic Island and Other Specs

A smaller Dynamic Island is expected, made possible by moving Face ID components under the display . Other notable upgrades include:

• 24MP front camera (up from 12MP) .
• A new dark cherry color option, described as a deep wine-toned red .
• An Apple C2 modem with mmWave 5G support .
• A 6.9-inch LTPO+ OLED display with 120Hz ProMotion .

The $200–$300 Price Hike: Why It's Happening

The price increase is the biggest story for many potential buyers. Apple CEO Tim Cook confirmed to The Wall Street Journal that increases are "unavoidable" due to a global memory chip shortage . Here's what the analysts are saying:

• IDC estimates a price increase of up to $200 .
• GF Securities analyst Jeff Pu forecasts an increase of $250–$300 .
• TechInsights estimates the base iPhone 18 Pro will cost roughly $270 more than the iPhone 17 Pro .
• Counterpoint Research puts the bill of materials (BOM) increase for the 1TB Pro Max at nearly $300 .

Putting those numbers together, the starting price for the iPhone 18 Pro could land between $1,299 and $1,399 in the US, with the Pro Max starting even higher .

Supply Constraints: AI Is Eating the Memory Supply

The root cause of the price hike is a global shortage of DRAM and NAND flash memory. AI datacenters are consuming an estimated 70% of global DRAM supply, forcing memory prices to surge 63–75% year-over-year . Manufacturers like Samsung and Micron have shifted production to enterprise-grade memory for AI servers, squeezing supply for consumer electronics .

As a result, the cost of the 12GB of DRAM in the iPhone 18 Pro could rise from about $39 (in the iPhone 17 Pro) to as much as $145 — a 272% increase . NAND flash costs are also climbing sharply .

The Bottom Line

The iPhone 18 Pro lineup looks set to be a landmark release: genuine firsts in chip technology, camera hardware, and launch strategy. But those innovations come at a steep cost — and the main reason has little to do with Apple and everything to do with an AI industry that is vacuuming up the world's memory supply.
