Samsung was earlier reported to be testing two prototypes of the Galaxy S25 Edge and decided to mass produce the version that was exceptionally thin at 5.84mm but would only ship with two rear cameras instead of the three on the other model. Naturally, the quest to deliver a sleek flagship would result in more than a fair share of compromises, which obviously means the company had to make a trade-off in the cooling solution too. However, one rumor claims that while the vapor chamber belonging to the Galaxy S25 Edge will be thinner, it will be larger than the one in the Galaxy S25 to optimize heat dissipation.
The vapor chamber on the Galaxy S25 Edge could effectively cool the components thanks to the larger surface area
The exact size of the Galaxy S25 Edge’s vapor chamber was not shared by @PandaFlashPro, but he mentions on X that the vapor chamber will be larger than the solution on the Galaxy S25. Given the sheer thinness of the upcoming flagship, Samsung would need to make adjustments in this area to cool all the components properly and effectively. A larger vapor chamber can compensate for its lack of thickness by widely spreading the heat, but we have to see various tests performed on the Galaxy S25 Edge before we provide an impartial verdict.
A thinner vapor chamber could also be the reason why the Galaxy S25 Edges ends up being the lightest flagship from Samsung’s current-generation lineup. As you can see in a hands-on video that was uploaded to YouTube but deleted shortly after, Samsung’s upcoming premium offering is as thin as one side of the Galaxy Z Fold 6, so one can immediately assume that the vapor chamber will match the size of the device’s thickness. So far, the only benchmark where we have been able to gauge the Galaxy S25 Edge’s performance is Geekbench 6.
"Confirmed"
Yes! The S25 Edge Cooling System is Thinner than S25 but Bigger than the S25. https://t.co/1teM1sj4MB— PandaFlash 𝕏 (@PandaFlashPro) February 24, 2025
With the Snapdragon 8 Elite performing equally to the same chipset present in other members of the Galaxy S25 family, Geekbench 6’s leaked benchmark is not a proper metric for sustained workloads because it only runs various tests for several seconds, which is not enough to let the chipset and other components properly heat up and work a sweat. Hopefully, with the Galaxy S25 Edge reportedly arriving in April, we will know more about its internals and vapor chamber size, so stay tuned.
