Apple is reportedly ramping up its emphasis on thermal management across upcoming iPhone devices. Fresh leaks indicate the firm has ramped up orders for vapour chamber cooling parts intended for its debut foldable iPhone as well as the upcoming 20th anniversary edition. This update builds on prior reports of more sophisticated cooling approaches planned for high-end models ahead. The company has yet to verify any specifics about these products or their components.

A Weibo update from tipster Fixed Focus Digital claims Apple has notably expanded its purchases of vapour chamber cooling plates. The source linked this step to plans for stronger cooling performance in the first foldable iPhone and the 20th anniversary models.

The update offers no further details on specs or release windows. Still the information matches the tipster's prior notes that the foldable model may include an advanced vapour chamber setup. Apple has not confirmed these elements.

Additional reports suggest Apple may raise output of its initial foldable iPhone to roughly 10 million units compared with an earlier projection of seven to eight million units.

Apple debuted vapour chamber cooling in the iPhone 17 Pro series. The approach moves heat from the A19 Pro chipset and distributes it over the aluminium frame to enhance dissipation under heavy use.

Earlier leaks pointed to vapour chamber cooling for the 20th anniversary iPhone models as well. The special lineup is expected to feature two variants with screen sizes matching the anticipated iPhone 18 Pro and iPhone 18 Pro Max.

Further claims indicate the anniversary iPhone may include a revised glass body and a nearly borderless display. The same source previously noted that Apple plans a return to glass construction and that production sites tied to the project have received upgrades.
