Sony Xperia Pro has the largest vapor cooling chamber in a phone yet

Peter, 15 March 2021

Every time a new gaming phone is announced we hear a lot about the cooling – so it is surprising that the biggest vapor cooling chamber is not found in a gaming phone but in the Sony Xperia Pro instead. Zack from JerryRigEverything has taken apart his fair share of ROG Phones, Black Sharks, Red Magics and so on, so he knows what he is talking about.

Sony used a plastic frame and plastic back on the Pro model rather than the metal and glass design of the Xperia 1 II. That may have improved durability (the plastic back is not going to crack easily), but it also complicated cooling.

A metal plate serves as the interface with various graphite sheets wicking heat away from components and leading it to the plate. This includes sheets that help cool the phone’s 5G antennas.

The metal plate in turn transfers heat to an enormous vapor chamber – it’s almost as tall and wide as the phone. The chamber then dumps all the heat out through the screen. Watch the video below for a few more interesting tidbits about the design.

Chances are that you’re not going to spend $2,500 on a phone to use the Xperia Pro. Especially since the long delayed launch means that the Pro is powered by last year’s Snapdragon 865. Still, gaming phone makers can probably pick up a few tips from Sony on cooling design.

In case you missed it, here is JRE’s durability test to see if Sony succeeded in building a phone durable enough for professionals.

Great, this isnt even about phones now.

Its not just the video, you dont see the difference in anything.

What? I actually said i see the difference between even a pentile 2k and rgb 1080. Read carefully.
