Apple has significantly boosted its orders for vapor chamber cooling systems, primarily to support production of its highly anticipated first foldable iPhone, according to a Chinese supply chain leaker. The move also points to advanced thermal management in the company’s upcoming Twentieth Anniversary iPhone slated for 2027. The information comes from the Weibo account “Fixed Focus Digital,” a source that has previously shared details about Apple’s foldable device. The increased orders will first go toward manufacturing the book-style foldable iPhone, internally referred to as the “iPhone Ultra,” which is on track for a September 2026 debut alongside the iPhone 18 Pro lineup. Apple has reportedly instructed suppliers to prepare around 10 million units of the foldable iPhone for 2026, an increase from earlier projections of 7–8 million. This ramp-up signals strong confidence in the device’s production readiness despite the complexities of its folding mechanism. Advanced Cooling for a Challenging Form Factor Fixed Focus Digital previously indicated that the foldable iPhone would feature “impressive” vapor chamber cooling, with Apple “going all out” on its thermal design. This makes sense given the device’s expected thin profile when unfolded (rumored around 4.5–5mm) and the space constraints of a foldable chassis, which could limit traditional heat dissipation options. Apple first introduced vapor chamber technology in the iPhone 17 Pro models last year. The system uses a small amount of deionized water to efficiently transfer heat away from the powerful A-series chip and spread it across the device’s aluminum frame, helping sustain high performance without thermal throttling. The same cooling approach is now expected to extend to the foldable iPhone Ultra and potentially the 2027 anniversary iPhones, which are rumored to feature dramatic edge-to-edge displays with glass curving around all four sides for a nearly borderless look. Broader Context and Timeline The foldable iPhone is expected to include a 7.8-inch inner display, a 5.5-inch cover screen, an A20 chip, and a Touch ID power button, with pricing likely starting near $2,000. Recent reports confirm that mass production is underway, with key components like OLED panels already in production at Samsung Display. Meanwhile, Apple’s 20th-anniversary iPhones are planned for two sizes similar to the iPhone 18 Pro models. These devices could mark a major redesign, potentially returning to an all-glass enclosure. MacDailyNews Take: This latest leak aligns with Apple’s aggressive push into new form factors while maintaining the performance and reliability standards users expect from its flagship devices. As the September launch approaches, more details on the iPhone Ultra’s final specifications are likely to emerge from the supply chain.
