Google Pixel mobile phone running daydream VR is also difficult to escape the dilemma of fever

Mobile VR mobile phone fever is a common problem at present, we know that computer vision recognition needs to process a lot of data. If we want to achieve 90FPS built-in location tracking on the phone, the heat of the phone will reach an unbearable level.

VR game applications have high requirements on processor performance. Basically, only the high-end flagship SOC can meet the mobile VR operating standards. For example, Daydream requires that the processor be at the lowest level.

At present, when the mobile VR on the market is running, the fever of the mobile phone greatly affects the VR experience of the user, and even the mobile phone of Google cannot escape such a problem. Recently, foreign media reported that Google Pixel and Pixel XL will experience overheating after 15 minutes of running in the DayDream VR environment. When the user encounters an overheating problem in the virtual reality experience, they will see a screen pop-up warning and the user will have to interrupt the experience.

Although there is no case of a user exploding when experiencing mobile VR, the problem of mobile phone fever is not solved, and there is no doubt that the user is still skeptical. After all, there is still risk.

Qualcomm's vice president of graphics and imaging, TIm Leland, said that in Qualcomm's reference design, the default is to keep the phone's temperature below 35 Â°C, but mobile phone manufacturers can set their own thresholds; On the other hand, some manufacturers are more aggressive in setting the CPU governor, which will make the temperature of the mobile phone reach 45 Â°C or above: "It feels like it will be very hot, but in fact it will vary according to the different materials of the phone case - each Plastics have different heat resistance properties."
