According to reporter Gurman, citing sources, the foldable iPhone is expected to be announced in September 2026, alongside the 'iPhone 18' series.

According to Nikkei Asia, 'they are facing problems during the testing phase, which could delay the mass production and product shipment schedule.' Gurman reports that 'the complexity of the new foldable display and materials may limit initial supply by several weeks, but the September announcement schedule remains unchanged.'

Gurman explained that the foldable iPhone is 'an important initiative for Apple, aiming to expand the iPhone lineup with new designs, higher-priced models, and enhanced features. It also aims to strengthen its competitiveness against Samsung and Chinese smartphone manufacturers, who have been offering foldable models for many years.' He described it as one of Apple's reforms following the slim iPhone Air.
