HTC One M9 surface temperature hits 132 degrees fahrenheit during benchmark test


HTC is hoping that its new flagship smartphone becomes hot, but not like this. A recent GFXBench benchmark test of the HTC One M9 found the device hitting a surface temperature of 132 degrees fahrenheit. Considering that other phones tested ran much cooler, we could deduce that something that was inside the HTC One M9 and not in the HTC One (M8), Apple iPhone 6 Plus, LG G3 and Samsung Galaxy Note 4 was the culprit. And that could be the Qualcomm Snapdragon 810 chipset which powers the HTC One M9, but not any of the other phones.

This would appear to be confirmation that the Snapdragon 810 is still suffering from the overheating issues that worried Samsung and consumers earlier this year. Still, LG said in January that the chip was one of the least overheating processors, and the chip powers the LG G Flex 2 and the upcoming LG G4. Last month, we reported on a test that showed the Snapdragon 810 running cooler than the Snapdragon 801.

While the HTC One M9 got so hot that you could fry an egg on the back of the unit, the other phones recorded much lower temperatures. For example, the Apple iPhone 6 hit 103 degrees fahrenheit and the HTC One (M8) moved the mercury to 102 degrees. At 100 degrees, the Samsung Galaxy Note 4 ran the coolest of all the phones tested. The LG G3 was the second hottest handset reaching a temperature of 108 degrees.

Keep in mind that the version of the HTC One M9 tested was running pre-release software, which could have muddied the results. Another thing to consider is that the Snapdragon 810 powered LG G Flex 2 hasn't had any reported overheating problems.

but one thing for sure note 4 is the COOLEST of all..

Well the note 4 isn't so hot.

First thing I may need to do after getting this phone 1. Root 2. Get a Custom ROM/Kernel 3. Undervolt the sh*t out of it.

Which would essentially make you stupid for not just buying the m8.

what's an Extremis?

he means enemies

He means Extremis, a group of villains who tried to replicate the super serum which ended up in them overheating and sometimes exploding.

You're kidding, right? The aluminum bodied phones should have a higher surface temperature because that means the aluminum is doing its job: superior heat dissipation. The One M9 is still way too hot. The plastic Note 4 is keeping a bunch of heat in, as is the G3, because plastic is a poor heat conductor. While two of the aluminum phones are doing their job, the G3, Note 4, and M9 are just cooking their internal components.

Cooking their internal components? Seriously? That must explain why I keep seeing all those charred Note 4s & G3s out there. Sad state of affairs.

You have got to be kidding. The iPhone 6 plus shown here has a little metal shield over its CPU. Then there is another metal shield covering the components and battery. Then comes the aluminum case. All to protect the Apples dual core 1.4 GHz CPU. Which is only running at 1.4 GHz. Yet the note 4 which not only does it run faster in real world and offers things like real multitasking and multi-window. Its physically running at 1.9 GHz with an octa core CPU. The note 4 also has 3 times the ram. So is there heat, sure there is, but the heat sink covering Samsung's board is also large and doing its job as well. And yet the Note 4 is running faster and doing more then that single tasking 1.4 GHz dual core CPU. Anything running at that speed should be able to run cool. I am surprised Apples CPU is running that hot at only 1.4 GHz with only 1 GB of ram.

PPL What did I tell you few weeks back ??? Huawei and MediaTek are the BEST ?? AND they WILL PREVAIL !!! Huawei THINKS !

What's the big deal? My Note4 Exynos reaches 150, overclocked and overclocked voltages. So what? I'm enjoying much better performance than standard locked crappy. Playing games and multitasking at extreme levels. I don't even bother touching there Cpu and Gpu are, which are on the top.

Don't mix CPU temperature with body temperature. My Galaxy Note 4 which is Exynos too doesn't reach 50 degrees Celsius even during very high and long lasting load. Doubt that the test in the article was very long.

"Another thing to consider is that the Snapdragon 810 powered LG G Flex 2 hasn't had any reported overheating problems" - cause it throttles and stutters all over the place, if those reports are to believed.

I read the review of the Flex 2 on the Verge website. They said the phone does fine with gaming and things of that nature but lags and stutters on simple tasks. They think it has more to do with LG's software than the processor.

its simple: SD 810 + metal body= performance and bad battery life, SD 810 + plastic body= less performance and less bad battery life.

I'm not sure you understood my comment. The reviewer said the phone performs fine when doing CPU intensive tasks but stuggles with simple ones. This has more to do with software than anything else. I'm also not sure how you came to your battery life conclusions.

45. medtxa

Yeah I understood your comment, I still post it anyway. My conclusions came from the logic that SD 810 throttle when it's too hot hence can't achieve the peak performance, metal body can save more heat than plastic, allow the SD 810 to maintain the performance longer and reach higher performance peak. The battery depleted faster if the processor can maintain the high performance longer. see..

Aluminum dissipates more heat than plastic. Plastic just holds the heat in, cooking your internals. Aluminum is far superior to plastic in regard to thermal properties.

The Verge also gave the LG G Flex 2 a 7.7 score because of its lagginess. The reviewer there makes the assumption that the lag is caused by software, but low benchmarks seem to point otherwise. Pocketnow's review of the G Flex 2 states outright that the lagginess is caused by thermal throttling. The reviewer there also states that games become laggy if any other program is running in the background. There were instances of the HTC One M9 failing to complete benchmarks because of overheating at MWC so I would be careful about blanket statements like "this has more to do with software than anything else".

Even if the benchmarks were low which they aren't, there are plenty of phones with mediocre specs that can run smoothly. The laginess in the UI is a result of poor optimization by LG. It'll be reaffirmed once reviews of the M9 come out. I didn't see any lag in video demonstrations of that phone. It appeared to me that the M9 was a little bit more responsive than the S6.

65. TAMARETTE

If that is the case, which is debatable, then HTC are clearly NOT the gods of software that some believe them to be. I'm really SHOCKED that the M9 appears to be more responsive to you. Just kidding, of course it does. How do you account for the HTC M9 failing to finish benchmarks at MWC? I've got to hear this. LOL

If that's true it could be result of the software not being final; benchmarks being ran multiple times on the phone in a short period; a bad unit; or the phone was having throttling issues. In any case, I'll wait for the reviews to come out that show real world usage and not these unique extreme scenarios.

A couple of consecutive benchmarks make the Flex 2 throttle down to about half the speed. That happens for a reason.
