New leak hints at vapor chamber cooling coming to iPhone 17 Professional

A picture shared by leaker Majin Bu provides what stands out as the clearest look but at Apple’s rumored resolution to a rising problem in high-performance smartphones: warmth dissipation. Right here’s what it appears to be like like.

In keeping with Bu’s sources, Apple is making ready to convey a vapor chamber to the iPhone 17 Professional lineup, a expertise already widespread in gaming laptops and high-end Android flagships.

Opposite to the graphite sheet cooling expertise utilized in iPhones at the moment, which spreads warmth throughout a floor, a vapor chamber works by way of part change: liquid contained in the sealed metallic plate evaporates when sizzling, strikes to a cooler space, condenses, after which cycles again once more.

Whereas this makes for sooner and extra even warmth distribution, it’s price noting that previous rumors and leaks accounted for the truth that Apple may use a vapor chamber as well as to its graphite cooling sheet, so this isn’t an both/or scenario.

What does it appear to be?

Due to what Bu says is a pre-production picture, we will have an thought of what the part may appear to be.

The picture exhibits what seems to be the bottom plate for the vapor chamber system, with intricate micro-perforated copper patterns typical of VC manufacturing.

Bu claims that the necessity for this method stems from a mixture of things:

“The necessity for this method turns into particularly clear when contemplating the brand new A19 Professional chip, which is predicted to generate substantial warmth not solely from gaming or GPU-intensive duties, but in addition from on-device execution of generative AI fashions. These workloads are extremely demanding and require sustained thermal efficiency over time.”

Along with the brand new cooling system, Apple is reportedly exploring lighter chassis supplies, probably aluminum, to assist with warmth dissipation from the body.

Do you assume Apple will make the bounce to vapor chambers this yr? Does your iPhone nonetheless run hotter than you’d like? Tell us within the feedback.
