Sony Xperia Z3+ put to the test – how hot does the device get during gaming and 4K video recording

A lot has been posted online regarding the overheating issue of the Xperia Z3+ which is most likely linked to the Snapdragon 810 from Qualcomm. Even Sony has acknowledged the issue and promised to release a software update to fix that.

However, we are obligated to look into the issue and we can certainly say there’s something wrong going on here. Even during light web browsing, installing an app or two or taking still shots rose the temperature of the device. The sensation of the hot surface was even worse due to the glass back of the phone. But before we show you how hot it gets, let’s take a closer look at the CPU and how it handles the usual daily tasks like web browsing, video playback, photo editing and writing.


After the initial CPU test, we ran Epic Citadel benchmark on loop that should imitate a long 3D gaming session that lasted for more than 45 minutes. The surface of the phone got quite hot especially near the camera sensor where the SoC is placed. It can get really uncomfortable to hold the phone at some point.

For our final assessment, we started recording 4K video as this is the most demanding task a SoC can handle. Unfortunately, though, the camera app shut down automatically when reached the temperatures you can see below and we recorded only under 4 minutes of 4K video. Other phones that we’ve tested were able to go for at least 10 minutes. We’ve also experienced shut-downs during recording normal FHD videos and taking photos.
