iPhone 17 Pro and Pro Max feature a thermal management system that includes an Apple-designed vapor chamber, delivering exceptional performance.
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…
