Snapdragon 810 is undoubtedly the strongest among Qualcomm's Snapdragon series processors. Its excellent computing performance, powerful GPU, network and other strengths make Snapdragon 810 one of the hottest processors at the moment. However, as the "cost" of powerful performance, heating is also a problem for many top processors, and Snapdragon 810 is indeed at the forefront of this. At present, when many flagships and Snapdragon 810 are already equipped with Snapdragon 810, we are also preparing to actually test whether Snapdragon 810 is hot or not.
V2.1 version is a legend? Is Snapdragon 810 still hot?
First of all, let’s roughly understand the specific specifications of Snapdragon 810. This chip adopts a 20nm process, is equipped with a quad-core Cortex-A57+quad-core Cortex-A53 architecture, and an Adreno 430 graphics chip. Snapdragon 810 also uses Cat.9 standard LTE support with three carrier aggregation, which can achieve three times the download speed compared to Cat.4, up to 450Mbps.

Our test used the OnePlus 2, which was just released last week. In fact, in the early publicity, many domestic manufacturers used the statement "Snapdragon 810 V2.1 version" and said that this version of Snapdragon 810 has been well controlled. Qualcomm denied it at a media communication meeting and said that it was related to the manufacturer's cooling solution.
OnePlus 2 should have put in a lot of effort in heat dissipation
This time, OnePlus 2's Snapdragon 810 has a patent for H-Cube software algorithm, and also has a thermal gel and a shielding layer of copper alloy. There are 3 layers of graphite sheets covered at the top. From the point of view, such a lineup can indeed quickly disperse the heat evenly, but piled up materials is one aspect, and the actual experience is another matter, so this time we still need to use actual tests to see if the Snapdragon 810 is hot.
First of all, we need to simulate a relatively complex scenario, because for many users, they can even feel that their phones are very hot when they browse Weibo and chat with WeChat. So we first use Antutu running scores to conduct a comprehensive simulation and record the surface temperature of the phone in different periods.
The temperature recorded for the first time is the state of the mobile phone at room temperature. Of course, it should be noted that this temperature is closely related to the weather and the environment at that time. The reason for measuring this temperature is to be able to clearly understand the temperature difference with the subsequent running score. The screen surface temperature is 28.2℃, and the temperatures of the back shell and metal back plate are 27.5℃ and 27.9℃ respectively.
The second record was the temperature measured after using Antutu running score for 10 minutes. We recorded the temperature of the screen, the back cover and the metal back plate of the open back cover respectively. When running for 10 minutes, the temperature of the screen is 31.3℃ and the temperature of the back cover is 30.6℃. The temperature at this time when the metal back plate of the back cover is 31.9℃.
The third record was the measured temperature after using Antutu running score for 30 minutes, and the temperature of the screen, back cover and metal back panel of the open back cover was also recorded. The temperature of the screen is 34.4℃, the temperature of the back cover is 35.7℃, and the temperature of the metal back panel when the back cover is removed is 36.8℃. After
has simulated the fever situation under the comprehensive situation, let’s take a look at another common situation - playing games. Today, with the continuous improvement of mobile phone performance, the graphics of mobile games are becoming more and more refined, and are also welcomed by more and more users. Playing games is definitely a "key project" that makes mobile phones "fever". So in this link, let’s test the temperature performance of Snapdragon 810 when playing games.
Because our test time, location and weather have not changed significantly, we still use the initial temperature data of OnePlus 2 measured in the previous group.
The first time node is still 10 minutes. After the 10-minute actual game trial, we will test the temperature of the screen, back cover and metal back panel of the back cover. At this time, the temperature of the screen is 34.2℃, the temperature of the back cover is 33.5℃, and the temperature of the metal back panel when the back cover is removed is 35.2℃.
The second time node is after the actual trial of the game for 30 minutes. At this time, we will record the temperature of the screen, the back cover and the metal back plate of the back cover that is opened. At this time, the temperature of the screen is 33.8℃, the temperature of the back cover is 34.2℃, and the temperature of the metal back panel when the back cover is removed is 35.4℃.
Through the numbers, we can see that the temperature difference during the actual measurement of the first set of running scores can still be clearly seen, but the absolute value is not very high; while the actual game tests did not change much significantly in the temperature during 10 minutes and 30 minutes, and from my personal actual feelings, the palms will feel warm, but there is no "fever", which means that it is at an acceptable normal temperature and will not cause people to feel uncomfortable. Through this test, we can see that Qualcomm officially stated that there is no problem with Snapdragon 810 not being hot, and the manufacturer's work in cooling design is crucial. OnePlus 2, which participated in our test, is indeed worthy of recognition in this regard.
