Galaxy S25 Ultra has larger vapor chamber to AI processing runs smoothly
Samsung launched the Galaxy S25 series at Galaxy Unpacked with some hardware improvements and many in terms of software. Notably, the Galaxy S25 Ultra features a larger vapor chamber heat dissipation system than its predecessors.
The Galaxy S24 Ultra device boasts an optimal thermal control system with a 1.9 times larger vapor chamber compared to the Galaxy S23 Ultra, and the Galaxy S25 Ultra has improved it even further, improving the device’s surface temperature while also maximizing sustained performance power.
According to Samsung, the Galaxy S25 Ultra has a 40% larger vapor chamber than the Galaxy S24 Ultra, which helps all intensive device usage and AI processing run smoothly. This is a big upgrade over the Galaxy S24 series.
In addition to this, the Ultra phone has a tailored thermal interface material (TIM) that delivers extra improvement in thermal efficiency.
The Galaxy S25 Ultra can maintain the processor’s top performance for longer with the large cooling system and tailored thermal interface material. This means you won’t experience hiccups, stutters, frame drops, or overheating when you run the phone under tough workloads for long periods of time.
Furthermore, the Galaxy S25 Ultra won’t experience significant performance degradation or overheating even when playing multiple back-to-back sessions of heavy games,
An image shared on X/Twitter by TechHome100 shows a head-to-head comparison of the two. This image shows that the S25 Ultra’s vapor chamber cooling area is much larger than that of the S24 Ultra. This makes sense considering that the device is slightly smaller and thinner than its predecessor.
