Whenever a new phone is launched, companies no longer focus solely on the processor and camera; another feature frequently highlighted is Vapor Chamber (VC) cooling. Currently, this feature is found primarily in gaming phones or flagship devices rather than budget smartphones. A vapor chamber is a cooling system designed to dissipate heat and keep the device cool.

What is a vapor chamber, and how does it work?
The vapor chamber inside a phone is a flat, vacuum-sealed metal container filled with a small amount of liquid. As the phone heats up, the liquid turns into gas; it then cools down and condenses.

Why is it essential for phones?
When a phone overheats, its performance drops—a phenomenon known as thermal throttling. This is often the reason behind frame drops while gaming. Vapor chamber cooling keeps the phone cool, allowing for extended gaming sessions and helping to prevent thermal throttling.

Keeps the phone cool during charging
Modern phones come with super-fast charging capabilities, which generate significant heat during the process. The vapor chamber helps keep the phone cool while charging rapidly.

Battery health
Excessive heat is detrimental to a phone's battery. High temperatures can cause the battery to degrade quickly and, in some cases, even increase the risk of it exploding. Vapor chamber cooling helps maintain battery health by keeping the device cool.
