Samsung has always made the vapor chamber a standard on its high-end smartphones, with the ‘Ultra’ variant getting treated to the largest solution. However, the company could make a drastic decision with the Galaxy S27 Ultra, which will help take its cooling capabilities beyond what current-generation devices are capable of housing. A tipster shared an alleged image of a prototype vapor chamber that is being tested for the Korean giant’s next-generation flagship, and to say that it is thick would be a gross understatement.
The tipster says the actual vapor chamber will be shrunk down to be outfitted in the Galaxy S27 Ultra without compromising the thickness
The picture shared by @SPYGO19726 on X shows a much thicker vapor chamber than what we have seen on smartphones. We can argue that, from this angle, it resembles something found in notebooks, with two copper bases on the top and bottom, with fins sandwiched in between to trap all the heat generated from the components, including the chipset. Of course, this would be the ultimate vapor chamber upgrade for the Galaxy S27 Ultra, but the limited space inside the smartphone means this approach will not be possible.
Instead, the tipster states that this vapor chamber will be shrunk to fit inside a handset, concluding that its footprint will be significantly smaller while being thinner. It should not be surprising that Samsung and a host of other companies employ these bulkier coolers to test out their chipsets, and it is likely that the Exynos 2600 could be cooled by the same solution during its initial testing phase when it ran circles around the Snapdragon 8 Elite Gen 5 and A19 Pro.
This cooler might be a reason why Samsung’s first 2nm GAA chipset scored unbelievably high in Geekbench 6’s latest single-core score, matching Apple’s M5 results, though a few skeptics have outright refuted those numbers as they did not appear in the benchmarking database. Still, assuming this leak is legitimate, Samsung is headed in the right direction in terms of maintaining chipset performance, although we cannot confirm whether the same shrunken solution will make its way to the Galaxy S26 Ultra next year.
Given that Apple has introduced vapor chamber cooling to the iPhone 17 Pro and iPhone 17 Pro Max for the first time, it makes sense for Samsung to try to develop more robust heat dissipation solutions for devices like the Galaxy S27 Ultra and its immediate successors.
