Apple Introduces Foldable iPhone Duo and iPhone 18 Pro Series

On September 9, 2026, Apple officially introduced its first foldable smartphone, the iPhone Duo, alongside the flagship iPhone 18 Pro and iPhone 18 Pro Max. European pre-orders opened on September 12, with general retail availability across the European Union scheduled for September 18, 2026. The iPhone Duo features an inward-folding flexible OLED main display paired with an external cover screen, running on Apple's new A20 Pro system-on-chip. In the European market, official launch pricing starts at 1,999 EUR for the base 256 GB iPhone Duo, while the iPhone 18 Pro starts at 1,329 EUR and the iPhone 18 Pro Max at 1,479 EUR. While Apple showcased a zero-crease titanium-alloy hinge mechanism and second-generation Ceramic Shield outer glass, precise internal battery capacities and component schematics remain unconfirmed pending retail teardowns.

What Changes for European and Slovenian Users

The release marks Apple's entry into a mature foldable segment currently contested by Samsung, Google, and Honor. For consumers in Slovenia and the broader European Union, the hardware aligns with current EU regulations, including standardized USB-C connectivity, unified fast-charging protocols, and mandatory software maintenance commitments extending several years into the hardware lifecycle.

The iPhone Duo operates on iOS 20, which incorporates split-screen multitasking, dynamic app spanning across the hinge boundary, and an external display mode that functions without opening the chassis. For standard form-factor buyers, the iPhone 18 Pro series introduces a smaller Dynamic Island cutout, a redesigned vapor-chamber thermal structure, and enhanced optical zoom modules. Both product lines ship without power adapters, requiring owners to utilize compatible USB-PD chargers rated for higher wattage inputs.

Durability, Hinge Architecture, and Repair Complexities

From a hardware service perspective, the introduction of a foldable device significantly alters mechanical reliability profiles. Foldable form factors inherently increase physical vulnerability: flexible ultra-thin glass (UTG) panels cannot use traditional rigid tempered protective layers, making them susceptible to micro-abrasions and impact damage along the central axis.

The iPhone Duo employs a multi-link geared hinge engineered to prevent particulate intrusion, yet micro-debris ingress remains an inherent long-term hazard for gear trains and flexible printed circuit (FPC) cables bridging the two chassis halves. Dual-display configurations also double the potential display replacement surface area. Furthermore, split-cell battery topologies, necessary to distribute weight across both halves, complicate battery replacement protocols, requiring individual adhesive pull-tab extractions and specific recalibration cycles.

Servicing these complex multi-display architectures requires specialized alignment jigs, controlled heat-separation tables, and OEM-grade replacement parts to preserve factory tolerances. In Slovenia, professional repair providers such as KRON IT handle hardware diagnostics and mechanical repairs for current and legacy smartphone platforms at dedicated facilities in Ljubljana and Maribor. Such workshops operate under ISO 9001 and ISO 14001 standards, providing a 12-month warranty on labour to ensure that hinge assemblies, flexible displays, and logic boards meet manufacturer specifications after service.

Practical Advice for Buyers and Current Device Owners

Prospective buyers should weigh adoption timing carefully. First-generation mechanical platforms frequently reveal long-term durability quirks that only manifest after months of real-world pocket carry, dust exposure, and repeated folding cycles. Users whose current iPhone 15 Pro or iPhone 16 Pro models function reliably may find greater value in deferring an upgrade until the foldable platform matures through secondary hardware revisions.

For those planning to transition to the iPhone Duo or iPhone 18 Pro:

• Perform Full Local Backups: Encrypt a complete backup via macOS Finder or Windows Apple Devices utility prior to migration, ensuring that two-factor authentication tokens and banking certificates transfer without data loss.
• Review Protection Plans: Given that foldable screen replacements historically represent up to 40 percent of a device's retail cost, verify accidental damage coverage options or case designs with dedicated spine protection.
• Recycle Responsibly: Older devices intended for retirement should be traded in or routed through certified electronic waste collection channels to recover critical raw materials, including rare earth elements and cobalt.
