Qualcomm's Snapdragon 810 processor is the company's best offering, it has 8 cores built with 64-bit architecture and it even integrates an LTE modem. The processor can handle some of the latest features found in smartphones such as 3D gaming and supports 4K video. Soon after it was announced, some rumors suggested that the company had been having trouble with the production of this chipset, as it presented some overheating. Those rumors were denied by the company and some manufacturers of mobile devices started using it in their devices. The first one to use it was LG in its G Flex 2, also denying the issues with the temperature. HTC used it in its One M9 and we recently found out that this phone and some others that are powered by this processor use a newer version called v2.1, which was supposed to handle the temperature in a better way.
At first, the One M9 suffered from overheating, but a few software updates were supposed to fix this. Last week, the OnePlus 2 was announced, using the same Snapdragon 810 v2.1 as previously teased by the maker. Now, some tests have been made to both of this devices to compare their temperature and this is how it turned out. The first test included the use of some basic functions such as making a phone call or using social media apps. The temperature of the One M9 ranged from 35 to 38 degrees Celsius and the ones from the OnePlus 2 were registered from 30 to 35 degrees Celsius. Another test was made using some more complicated tasks such as 4K video recording and running games with intense graphics. In these instances, the One M9 recorded temperatures from 40 to 45 degrees Celsius and the OnePlus 2 registered temperatures of 38 to 40 degrees Celsius. A final test was done running apps in the background and some benchmark tests, which resulted in temperatures of 47 to 49 degrees Celsius for the One M9 and the OnePlus 2 recorded temperatures ranging from 45 to 46 degrees Celsius.
In conclusion, the OnePlus 2 produces less heat than the One M9 in every scenario, but the report mentions that the One M9 used the previous version of the processor contradicting what was said by HTC's Jeff Gordon. Whether that's the reason of the difference of temperatures between the devices or some kind of software optimization, the temperatures in both devices were still considered high, compared to the ones reached by devices with other processors. So the controversy surrounding the Snapdragon 810 is unlikely to stop anytime soon, even though more devices come to market including it.
