Do Vapor Chambers ACTUALLY Work? | Redmi K20 Pro

What actually happens when you put a copper vapor chamber in the Redmi K20 Pro? In this video, I test the phone with and without a vapor chamber under the same conditions to see whether it can actually make a difference in real-world sustained performance. I tested AnTuTu, 3DMark Wild Life Extreme Stress Test, and Geekbench 7, along with surface temperature using an IR thermometer and overall battery consumption. The results were interesting ,there was a slight performance improvement, but the bigger difference was seen during sustained workloads, heat spreading, and battery drain. And for an older Snapdragon 855 device, the Redmi K20 Pro is still performing surprisingly well with Android 17 through a custom ROM.
