Foldable 'iPhone Ultra' Rumored to Feature Vapor Chamber Cooling Despite Thin Design

The foldable iPhone Ultra will feature a vapor chamber cooling system and launch in September. The device is expected to include a vapor chamber thermal plate similar to the iPhone 17 Pro. A leaker named Fixed Focus Digital reported that pre-assembly manufacturing processes are under pressure. Production ramp-up difficulties are cited as a key challenge. The September launch schedule remains unchanged according to the leaker. The vapor chamber cooling helps manage heat in thin form factors.
