HTC One M9 overheats to 55 degrees Celsius in GFXBench

According to a test performed by a Dutch tech website, the HTC One M9 is hotter than any other smartphone, and this in the literal sense. The tests show that the HTC One M9 overheats up to 55 degrees Celsius when passing through GFXBench tests.

A fresh report from shows that the HTC One M9 gets very hot under heavy load, with the smartphone's surface temperature reaching 55 degrees Celsius in some cases. The octa-core Qualcomm Snapdragon 810 chip is likely to be the culprit for these overheating issues. Over the past couple of months, multiple rumors and reports claimed that the Snapdragon 810 is plagued by overheating issues, and some rumors claim that the high temperature is exactly the reason why Samsung completely avoided using the chip in the Galaxy S6 and Galaxy S6 Edge flagships.

When testing the performance of the HTC One M9 in GFXBench - one of the most popular benchmark apps available for Android - the Dutch testers found that the M9 gets much hotter than every other flagship smartphone included in the test. The Samsung Galaxy Note 4 reached about 38 degrees, the Apple iPhone 6 Plus heated to 39 degrees, while the LG G3 surface temperature reached 42 degrees. The HTC One M8 was also included in the test and reached a surfaced temperature of about 39 degrees.

The thermal imagery shows that the HTC One M9 heats like a furnace compared to the other smartphones. The people who performed the test claim that the One M9 got so hot during the test that holding the device became quite unpleasant.

Interestingly, not long after the test results were published, HTC's Jeff Gordon came out on Twitter and commented that all of the pre-launch One M9 benchmarks are skewed by the fact that the One M9 isn't currently running the final version of the software. Yesterday HTC decided to postpone the One M9 release date in Taiwan as the One M9, confirming with a Chinese news agency that the M9 is still waiting for the final software update.
