Apple Delays Mass Production of Foldable iPhone Ultra for Rigorous Testing

Production of Apple’s first foldable iPhone — anticipated to carry the name iPhone Ultra — stands at only several hundred units per day as of late August, according to supply chain sources cited by Nikkei Asia. The device is scheduled for announcement on September 9, and immediate sell-out is considered nearly certain.

The root of the bottleneck

The constraint does not stem from raw material shortages. Instead, Apple introduced rigorous quality assurance protocols in August that delayed mass assembly by multiple weeks. Each unit undergoes individual evaluation for display flatness, visibility of the fold crease, and hinge functionality — three failure points historically associated with competing foldable devices.

Shipment targets versus reality

Analysts had projected year-end shipments of 8 to 10 million iPhone Ultra units. Achieving that volume would require daily output in the tens of thousands. Factories are operating continuously, yet current production levels fall significantly short of that threshold. MacRumors verified that low yields in hinge and display manufacturing constitute the primary cause of the supply limitation.

Regional rollout and pricing

The United States is expected to receive the iPhone Ultra first, followed by the United Kingdom and other international markets in a phased release — potentially delayed until October or later, per ChannelNews reports. UK retailers including Currys, John Lewis, and Carphone Warehouse are anticipated to experience intense pre-order demand once Apple opens reservations.

Pricing is expected to begin at $1,999–$2,399, with high-end configurations exceeding $3,000. That positions the device against the Samsung Galaxy Z Fold 8 Ultra, which starts at approximately £1,899 in the UK and reflects eight generations of foldable development.

Practical availability outlook

Consumers aiming to secure an iPhone Ultra before the holiday season are advised to pre-order immediately upon reservation opening. Supply constraints are forecast to persist well into late 2026. For those unwilling to wait, Samsung and Xiaomi currently offer established foldable alternatives at comparable or lower price points, backed by fully operational service networks.
