Apple Unveils iPhone Duo Foldable and iPhone 18 Pro Series

Apple’s event on September 9, 2026, signaled a fundamental shift in the company’s product strategy. Led by new CEO John Ternus following Tim Cook’s retirement, the keynote prioritized high-end hardware over a standard yearly refresh.

Instead, the focus turned toward the iPhone Duo, Apple’s first foldable smartphone, and a significantly upgraded iPhone 18 Pro lineup.

The iPhone Duo: Apple’s First Foldable

The iPhone Duo introduces a book-style folding design featuring a 5.4-inch outer display and a 7.6-inch folding inner display. To differentiate the experience, the inner screen utilizes a nano-texture finish to reduce glare.

Pricing for the iPhone Duo places it at the top of Apple’s mobile hierarchy. The base 256GB model starts at $1,999, with costs scaling up to $3,199 for the 2TB storage tier. Pre-orders for the Duo are scheduled to begin on October 16, with retail availability following on October 23.

iPhone 18 Pro and Variable Aperture

The iPhone 18 Pro and Pro Max received a $100 price increase this year, starting at $1,199 and $1,299 respectively. The primary hardware justification for the price hike is a new 48MP Fusion Main camera featuring a variable aperture system—a first for the iPhone. This allows for more precise control over depth of field and light intake in varying environments.

Both Pro models also feature a refined Dynamic Island. The interface element has been reduced in physical size and upgraded via software to display up to three Live Activities simultaneously. Both the Pro and the Duo are powered by the new A20 Pro chip. Built on a 2-nanometer architecture, the chip includes a 32-core Neural Engine and a 50% increase in memory bandwidth compared to its predecessor.

Wearables and Health Monitoring

Apple also refreshed its wearable lineup with the Apple Watch Series 12 and Apple Watch Ultra 4. Both models introduce a new “Readiness” score, which analyzes recovery metrics to advise users on their training intensity. Technical upgrades include a new Health Sensing System capable of 5-second heart rate monitoring intervals.
