Apple has begun the first internal prototyping stage for its inaugural foldable iPhone, according to a DigiTimes report that cites supply-chain sources. The handset entered the P1 phase in June, and each prototype cycle is expected to last about two months. If the schedule holds, Apple plans to complete prototype testing by late 2025 and move the device into Engineering Verification Tests, keeping it on track for a commercial debut in the second half of 2026, likely alongside the iPhone 18 line. Assembly partners Foxconn and Pegatron have been tapped to validate yields once prototyping concludes, the report said. Apple is aiming for a book-style design to compete with Samsung’s Galaxy Z Fold series and other foldables, though final specifications remain under evaluation. At the same time, Apple has put its separate foldable iPad effort on indefinite pause. Higher production costs, manufacturing challenges with flexible displays and tepid consumer demand for larger foldable devices prompted the decision, allowing the company to concentrate resources on delivering its first foldable iPhone.
