Samsung announced the Galaxy A57 on March 25, 2026, and spent most of the event talking about AI features and camera improvements. What they barely mentioned is the part that matters most for anyone who games or multitasks heavily on a mid range phone: the cooling system got a serious upgrade.
I am Ameer Hamza, and at Global Tech Press, we pay attention to the parts Samsung leaves out of its keynotes. This is one of those parts.
The Vapor Chamber Is 13% Larger Than the A56
To support the increased performance from the new processor, Samsung has equipped the Galaxy A57 with a larger vapor chamber cooling system. The Galaxy A57 features a vapor chamber cooling system that is 13% larger than the one in the Galaxy A56.
That number comes from SamMobile’s confirmed reporting after launch, not a leak.
A leaked image shared by @Alfaturk16 on X showed the Galaxy A55, A56, and the new A57 side by side with their back panels removed. The A57’s cooling chamber is visibly larger than both predecessors.
If you have been following our coverage, we broke down the Galaxy A57’s 13% bigger vapor chamber when the teardown first surfaced.
Why This Matters for Everyday Use
Combined with the new Exynos 1680 processor, which is built on an enhanced 4nm fabrication process, the upgraded cooling system should help the device sustain performance more effectively than its predecessor.
In plain language: the phone throttles less during heavy tasks.
This could allow the Exynos 1680 chip inside the phone to sustain peak performance and prevent thermal throttling. This massive cooling surface can dissipate heat faster, letting the chipset cool down, improving high end gaming performance and multitasking.
If you play PUBG Mobile, Genshin Impact, or any demanding title for more than 20 minutes, you will feel the difference. The Galaxy A57 with its Exynos 1680 chipset achieves an AnTuTu score of around 1,138,000. It ships with One UI 8.5 based on Android 16. In gaming tests, it supports PUBG Mobile at Extreme settings, delivering up to 60 FPS.
We covered the Galaxy A57’s gaming performance and why it costs more than the A56 earlier this week.
Thinner Body, Bigger Cooler
Here is the part that surprised me.
This enhanced thermal management doesn’t add any bulk. In fact, the Galaxy A57 is trimming down with an ultra slim 6.9mm profile and 179 grams of weight. This is despite the smartphone featuring a 5,000mAh battery, making it one of the thinnest A series phones to date.
For context, the Galaxy A56 was 7.4mm and 198g, making the A57 roughly 7% thinner and about 10% lighter.
Samsung fit a larger vapor chamber into a body that is thinner and lighter. That required a complete internal redesign. Fitting a larger vapor chamber into a slimmer body hints at careful internal redesign from PCB layout to heat spreader geometry and adhesive stack ups.

The Bottom Line
Samsung has been increasingly using bigger vapor chamber systems in its mid range and high end phones so that chips can better use all that processing performance for a longer period. Even the Galaxy S26 series uses bigger vapor chambers than phones in the Galaxy S25 lineup.
The Galaxy A57 is the first A series phone where that flagship cooling philosophy has trickled down in a meaningful way. Samsung just did not bother telling most people about it.
Now you know. If you are buying the A57, you are getting a phone that handles sustained load better than any mid range Samsung before it. And that is worth more than any AI feature Samsung spent 20 minutes demoing on stage.
