Sony has just announced the 4K screen-toting Xperia Z5 Premium, despite its earlier-generation phones being plagued with 4K overheating issues.
This begs the question, how will the new phone cope with showing a 4K image on a 4K screen, when its mobiles have been known to overheat and shut down when asked to cope with the demands of the imaging tech.
We put this question to Jun Makino, the Senior Product Manager at Sony’s mobile division.
He said: "Heating is a constant battle, but all our devices are tested to meet the standard levels of heating.
"In the Xperia Z5 series, we have worked to bring in a power saving algorithm into the software.”
Makino added: "We look at process by process, and see how much it generates heat and how much this affects the experience - then we optimise every process for the device.
"On top of this, we also have a more power saving design and hardware components to diffuse the heat.”
We hope this has solved the issue, and that showing a 4K image on a 4K screen doesn't generate anywhere near the same heat as recording a 4K video.
When we asked previously, uSwitch was told the best way it to record this type of video was for just a minute or two. That seems like a bit of a cop out to us.
