weibo leaker fixed focus digital shared a new post Today’s release timing update for the iPhone Ultra has revealed a feature not previously rumored – a vapor chamber.
iPhone Ultra will have vapor chamber for cooling, September launch still planned per leaker

Apple is preparing for mass production of its foldable iPhone Ultra, and new leaks keep coming about what to expect.
The latest details come from Fixed Focus Digital, which Posted today The iPhone Ultra has “impressive VC (vapor chamber) cooling performance” (translated).
This is the first time we’ve heard of the iPhone Ultra featuring a vapor chamber.
Apple added vapor chambers to the iPhone 17 Pro and iPhone 17 Pro Max last year, and they seem to have been a huge success.
The vapor chambers combined with the switch to aluminum have done wonders for the iPhone’s ability to maintain performance at a high level. In contrast, the iPhone 15 Pro and iPhone 16 Pro had issues with overheating under pressure.
The iPhone Ultra adding a vapor chamber to such a thin frame is surprising, but there’s good news. This helps ease some of my concerns about the device’s use of titanium in the frame.
With this reveal, the leaker says that all signs indicate that the iPhone Ultra is on track for a September release as originally planned. This is despite various rumors about production hurdles.
Finally, the leaker teased that they will have more big news to share tomorrow related to Apple’s foldable.
Are you planning to buy the iPhone Ultra when it launches? Let us know in the comments.
