The Sony Xperia PRO has a larger vapour chamber cooling solution than gaming smartphones
JerryRigEverything has followed up his Xperia PRO durability test with another video about the US$2,500 smartphone. This time, the YouTuber has provided a look at the Xperia PRO's insides, including the interior of its vapour chamber cooling solution.
Unsurprisingly, the Xperia PRO and Xperia 1 II share many similarities, such as their motherboard design and the same 4,000 mAh battery. However, Sony has included two mmWave antennas in the Xperia PRO that it did not include on the Xperia 1 II, albeit these are in the place of the latter's wireless charging coil. These mmWave antennas also have graphite strips that dissipate heat via the device's metal backplate.
The Xperia PRO has a different cooling solution, too. As the video below shows, Sony has equipped the Xperia PRO with a large vapour chamber that spans most of the display. A copper sheet sits between this and the display, which should help transfer excess heat out of the device's front.
JerryRigEverything speculates that Sony included such a large vapour chamber because of the Xperia PRO's plastic chassis, which is worse at expelling heat than the metal body of the Xperia 1 II. The vapour chamber is also one of the largest found in any smartphone, including gaming smartphones like the ASUS ROG Phone 5.
