Samsung Galaxy S25 Ultra teardown reveals noticeably larger vapor chamber than predecessor

Samsung's latest line of flagship phones come with the Snapdragon 8 Elite for Galaxy. It's basically an overclocked variant, with recent benchmark runs revealing 150MHz higher clocked Prime CPU cores and a 100Mhz boost on the GPU. These are some noticeable clock speed bumps when compared to the standard version.

This overclock would naturally mean better performance than the regular version of the Snapdragon 8 Elite, and to keep this customized SoC cool, Samsung claims to have integrated a 40% larger cooling system in the Galaxy S25 Ultra. As a teardown has revealed, the top-end flagship phone indeed sports a noticeably larger vapor cooling chamber than the predecessor.

It's unclear whether the cooling setup of the standard Galaxy S25 and S25 Plus saw a similar improvement. Nonetheless, given that the S25 Ultra is thinner than its predecessor, it's quite impressive to see Samsung integrating a larger vapor cooling chamber inside it.

As for whether the larger vapor chamber is doing its work, it's too early to come to a conclusion. Recent benchmark runs have revealed that the overclocked scores aren't really that impressive. However, things could change after the Galaxy S25 series starts shipping (pre-order S25 Ultra on Amazon), as Samsung may not have fully tweaked the software for performance yet.

If the larger vapor cooling chamber and overclocked SoC do deliver, it would be great news for gamers. Past gaming tests showcased that the Snapdragon 8 Elite is a very capable SoC, and it even performs well in terms of emulating Windows games.
