Apple’s long-awaited entry into the foldable phone market may finally be taking shape with some notable engineering choices. A new leak has surfaced well ahead of the anticipated launch, offering another glimpse into what the company reportedly plans to call the iPhone Ultra.
A Weibo tipster claims the device will ship with a vapor chamber to keep temperatures in check. That detail points to Apple prioritizing sustained performance, even in a form factor that presents unique thermal challenges. The same source says Apple has delivered “impressive VC cooling performance” on the iPhone Ultra. That is no small feat if the Foldable iPhone Ultra Leak Exposes Dual Camera Layout and Fresh Design Details holds up, since the phone is expected to unfold into an exceptionally thin profile. Cramming a vapor chamber into such a slim chassis would require significant engineering work, but the tipster suggests Apple has pulled it off.

In a separate post, the leaker also pointed to a liquid metal hinge for the iPhone Ultra. The timeline appears unchanged, with the device still expected to arrive in September. This development is particularly relevant given that earlier reports have not all been smooth sailing for the project. The Apple iPhone Ultra prototype hinges face reliability issues that engineers have been working to resolve, making the liquid metal hinge detail a notable sign of progress on that front.
Apple brought vapor chamber cooling to its lineup for the first time with the iPhone 17 Pro and 17 Pro Max. Extending that technology to a foldable design would mark another step in the company’s thermal management strategy.
