The Snapdragon 810 is a blazing fast processor… literally. In spite of stellar performance, reports pit the 810 among the hottest running processors on the market, causing major concern in the Android community. Qualcomm has gone on the record to say overheating issues are complete "rubbish," but we still wondered: does it really get hotter than some other alternatives?

The latest device to sport the 810 is, of course, the OnePlus 2. Representatives from OnePlus assure us that they've pulled out all the stops to ensure the 810 runs cool, but if you know anything about us here at TechnoBuffalo, you know we're going to put that to the test.

The devices we'll be using in this test are:

  • Nexus 6 (2560 x 1440) – Snapdragon 805
  • LG G4 (2560 x 1440) – Snapdragon 808
  • LG G Flex 2 (1920 x 1080) – Snapdragon 810
  • HTC M9 (1920 x 1080) – Snapdragon 810
  • OnePlus 2 (1920 x 1080) – Snapdragon 810
  • iPhone 6 (1920 x 1080) – Apple A8
  • Galaxy S6 (2560 x 1440) – Exynos 7 Series

We ran the same video on all seven devices at full brightness, volume at zero, and all apps closed but YouTube. All devices are currently up to date running the most recent version of the software offered by their respective manufacturers. At the conclusion of the video, we used a laser thermometer to measure temperature in 5 quadrants of the back of the device to account for placement of the processors. We then combined the temperatures to get an average for the device.

Here are our results listed from hottest to coolest:

The results were surprising! As it turns out, the OnePlus 2 is the coolest running device rocking a Snapdragon 810. The title of coolest flagship, though, goes to the Samsung Galaxy S6. This shouldn't come as too much of a surprise given that the Exynos is Samsung's very own silicon.

There you have it. The OnePlus 2 does indeed run the 810 cooler than its compatriots. What else would you like to see us test? Let us know in the comments!
