Leaker Fixed Focus Digital has disclosed that the upcoming iPhone Ultra will feature a vapor chamber, a significant enhancement aimed at improving the device's cooling performance. This is the first mention of such a feature for the iPhone Ultra, which follows the successful implementation of vapor chambers in the iPhone 17 Pro and Pro Max. These cooling systems are crucial for maintaining high performance, especially given the overheating issues reported in the iPhone 15 Pro and iPhone 16 Pro models. The integration of a vapor chamber in the iPhone Ultra's design, which includes a titanium frame, is seen as a positive development. Additionally, the leaker confirmed that the iPhone Ultra is on schedule for a September release, countering earlier rumors of production delays. More information regarding Apple's foldable devices is expected to be shared by the leaker in the coming days, generating further excitement among potential buyers.
