(Update: post-update test) You may want to take that HTC One M9 overheating report with a grain of salt

Update, March 23: Tweakers retested the One M9 after the device received an update last week. With the new software, the device heats up much less, as shown in this second thermal image.

tweakers one m9 2

It’s clear that on the original software, the device didn’t throttle when running the GFXBench benchmark, which caused it to overheat up to a whopping 55 degrees. What’s not clear is the reason: was it because of a bug, faulty configuration, or was it because throttling was disabled on purpose for that specific benchmark app?

AnandTech reported similar findings in its One M9 review. According to the respected website, the M9 now throttles under heavy load, which keeps heat in check but also affects performance. Here’s the relevant paragraph:

Friday’s software update introduced significant changes to the phone’s power and temperature management capabilities, which in turn has introduced a significant changes in the phone’s performance. HTC’s notes on the matter are very brief – updates to the camera, the UI, and thermal throttling – in practice it appears that HTC has greatly altered how the phone behaves under sustained loads. Our best guess at this point is that HTC appears to have reduced the maximum skin temperature allowed on the phone, which means that for short, bursty workloads that don’t approach the maximum skin temperature the changes are minimal, but for sustained loads performance has gone down due to the reduction in the amount of heat allowed to be generated.

Original post, March 16

According to a report that surfaced earlier today from Dutch website Tweakers, the HTC One M9 running the popular benchmarking app GFXBench suffers from significant overheating issues. The website measured the One M9 along with various other high-end devices through a thermal camera, and reported each of the device’s temperatures. The One M9 became significantly hotter than all the other handsets, reaching up to extreme temperatures of 55.4 degrees Celsius, or just over 131 degrees Fahrenheit. In the image provided, no other handset even comes close to the One M9’s numbers. Take a look at the image below for more information.


The report states that these high temperatures were reached only when running the benchmark app. When playing games like Asphalt 8 and Assassin’s Creed: Pirates, the temperature stayed around 42.5 degrees Celsius.

The reasoning behind this overheating issue? Most notably, the One M9 is running on Qualcomm’s Snapdragon 810 processor, which hasn’t exactly gotten the best track record for its performance since its release. Samsung ultimately decided to pass on the processor with the Galaxy S6 and S6 Edge handsets, possibly due to overheating issues that the processor has been rumored to have.

Comparatively, a few reports have also stated that the Snapdragon 810 doesn’t cause any overheating issues whatsoever. Anandtech tested the chip, and essentially said there were no overheating issues to be found. Now, of course the processor will run differently when its performing in different handsets, so the claims against overheating issues in this instance with the One M9 don’t really stand up.

Before we get too far ahead of ourselves on the processor overheating issues, there are a few other variables that come in to play. For starters, the HTC One M9 hasn’t been released yet. The handset in the test was not running even close to final software, which likely plays a big part in its overheating troubles. HTC recently delayed the launch of the One M9 in Taiwan to make some last minute software adjustments. While there’s no information on the software fixes it’s receiving, HTC is obviously still working on the handset to ensure the device’s stability.

The last thing we need to think about is the feasibility of this data. A metal device reaching temperatures of over 131 degrees could be dangerous to the human skin, and would likely be unbearable to hold for an extended period of time. By no means am I saying that the benchmark scores are inaccurate or that the temperature is wrong. But what I am saying is that HTC probably wouldn’t release a handset that overheats this much. They’ve been testing this device for months with the exact same chipset, and have presumably made adjustments where they see fit. Especially given the company’s financial standpoint in the mobile division, you’d think HTC wouldn’t overlook an issue this major.

The device we get in our hands in a few weeks will undoubtably be different from the device Tweakers is using in their report. And although the website’s findings coincide with just about everything we’ve been hearing about the Snapdragon 810, we need to withhold our judgement until we actually get our hands on the consumer-ready devices.

    HTC devices all run hot. It’s the risk you take with an all metal like body. iPhones run hot too when pushed. I’ve experienced massive heating issues since the M7. Now you add that the 810 has already heating issues (confirmed with the G flex 2) you have a recipe for problems. Doesn’t matter if you tweak the software it won’t do much. LG can sort of walk away safely because they are keeping with the plastic. It’ll be interesting how the M9 will do but so far a lot of downsides to owning it.

    • Phil

      Agreed, I hope that Qualcomm irons out the problem before the Z4 comes out lol.

    • Allen Cross

      HTC devices all run hot.

      True enough; that metal body transfers thermal energy quite nicely, with the result that your hand becomes the heat sink. My original HTC One (M7) was perfectly capable of reaching uncomfortably temps. in remarkably short order, despite using the lowly Qualcomm Snapdragon 600 (1.7 GHz) SoC.

      Now you add that the 810 has already heating issues (confirmed with the G flex 2)…

      As I’ve noted above, I’d suggest getting a better example than LG’s G-Flex 2.

      LG have a history of questionable design decisions, evinced by demonstrable performance issues not shared by other devices with the same SoC. And before somebody brings it up, let’s note that heavy throttling is found in at least the past generation of flagships…again, well ahead of Snapdragon 810.

      • I agree, Nexus 4 is the prime example of bad design. I heard G3 also getting hot easily. So far, it seems the best device LG has ever made is the G2.

    • Chris

      You mean all devices run hot….

  • Phil

    If the OneM9 gets that hot on a bench mark test, how’s it going to do on a half hour or longer gaming? I mean bench mark test usually only take a couple minutes. This could be a huge problem for HTC and others using the SD 810. There is also evidence in the LG G Flex 2 poor performance.

    • Allen Cross

      There is also evidence in the LG G Flex 2 poor performance

      ‘Evidence’? Maybe, but it’s evidence of LG’s incompetence.

      LG’s original G-Flex also had notorious performance issues, despite using Qualcomm’s Snapdragon 800 SoC…exactly the same 2.26GHz quad-core CPU found in the Nexus 5, which to this day exhibits no such inadequacies.


      • Guillermo Osterrieth

        Thats absolutely not true the flex 1 is one of the fastest phones you can get

        • Mike Bastable

          blindingly fast in fact

          • Guillermo Osterrieth

            Internet is full of shit. reviewers all across internet praised the g3 which i got in exchange for the flex and it stutters all the time. And is much slower than flex

          • it even won the title of best device of 2014 on MWC.

    • Guest123

      If you were able to read dutch and examined the source material, you’d see that during 3d gaming (playing asphalt 8 and assassins creed:Pirates) although higher than other handsets, the heat topped out at 42.5 Celsius (~107 Fahrenheit).

      “…Bij het gebruik van 3d-games als Asphalt 8 en Assassin’s Creed: Pirates loopt de temperatuur ook hoger op dan bij concurrenten, maar dan blijft hij rond de 42,5 graden…”

  • Twens

    I hope this doesn’t sound like a troll attempt but I think the iPhone 6 plus is an equally hot device. Mine gets so hot sometimes I need to turn it off and allow it to cool down. I face some lags here and there also, read about it on macrumor and it seems I’m not alone in terms of the lag issue. Apple isn’t leaving up to the hype lately, I’m really disappointed in my purchase. Will be getting the new s6 edge.

    • Karl Dagenais

      I’ve heard my fair share of stupid **** in my life, but that beats most of it.

  • John Kar

    Anandtech’s analysis is not accurate, since they’re using a reference device the size of a tablet, whose size helped with thermal constraints.

    Who knows what expensive cooling innards they put inside the device?

    Also, Tweaker is a very reliable tech website. Think of it as a Dutch Anandtech.

    What’s concerning is the battery life of the M9.


    Honestly, this article seems like damage control to not get on htc and Qualcomm’s bad side.

    • Tjaldid

      4 cores vs 8 it seems pretty straight forward to me

      • Snapdragon 810 basically has 4 cores only. 4 are for power saving and they hardly consume any power compared to the other 4 monsters.

        big.LITTLE actually saves battery compared to quad-core system.

        Obviously if a phone will overheat, it will waste energy as it gets converted into heat. Maybe they will throttle the SoC to prevent it from heating like the G Flex 2.

        • John Kar

          “big.LITTLE actually saves battery compared to quad-core system.”

          So why does the M9 have worse battery life than the M8? Hell, its battery life is worse than last year’s flagships.

          • The reason is given in my comment. Read it fully. The chip heats and energy gets wasted leading to poor battery life. Octa core has nothing to do with it. Qualcomm is new to implementing stock ARM cores. Wait for the S6 battery life.

          • John Kar

            We already have the S6’s battery life from 2 sources.

            The first source says the S6’s stand-by time and 3G talktime is slightly less than the S5, but its web-browsing time is 2 hours above the S5.

            The second source says the S6’s battery life is “substantially” superior to the S5, with geekbench’s battery life test giving the S5 5 hours while the S6 8.5 hours.

          • S6 is still running pre release software. I won’t judge the battery life now. But please give me the link

          • John Kar



            As a note, these reviews are with the March 10th firmware update, and Samsung told everyone on March 12th that there will be a final software update soon that will deal with improving battery life. Even without that update, the figures are quite impressive.

          • Anonymousfella

            How does geekbench measure battery runtime? Does it keep running a set of algorithms till the battery dies out? I’m curious

          • John Kar

            It runs heavy CPU-tasks in the background, so those numbers are only accurate for intensive tasks like gaming and web-browsing.

          • SubX

            Web browsing is NOT an intensive task. In fact, it would be one of the least intensive!

          • John Kar

            Web browsing is considered an intensive task by most reviewers.

          • Abhinav Kochhar

            Can you post the link for Samsung’s announcement of march 12th regarding firmware update?

          • John Kar

            It wasn’t a public announcement. It was a private announcement to reviewers. A person with the S6 (He made multiple videos of the S6, so it’s not some clown making up BS) said that Samsung told everyone on March 12th that the final S6 will have improved battery life, so current testing on battery life won’t be accurate. Almost everything else should be okay.

            This is why most reviews for the S6 out right now only give a subjective measure for battery life like “It’s great and easily lasts me a day” instead of giving hard numbers. They’ll update their reviews with the proper numbers once the device is out.

          • mobilemann

            i have a hard time believing this when your avatar currently is of a overheating M9 from one particular article:D

          • Lol. That’s for fun.

          • SubX

            You don’t even know this. No one does except HTC! The f-ing thing isn’t even released yet so how can you even speculate? What a f-ing stupid thing to say!
            For one, the battery is larger and running a less power hunger version of Android, so I fail to see how it would be worse!
            So until the actually consumer M9 is released, shut up all of you!

    • sonafitse

      This looks like AA’s appeal on behalf of either htc or Qualcomm. Surely, this article could have finished with a neutral ‘remains-to-be-seen’. AA you are journalists on behalf of consumers. Cut the corporate crap!

      • John Kar

        If I had to guess, HTC turned off thermal throttling for the preview units so that no reviewer experiences lag and stuttering and writes a bad review.

        In the consumer version, the throttling will be taken up a notch, which should compromise user experience.

        Who would’ve guessed that it will be the M9 that lags and stutters while the S6 has a lag-free experience?

        • SubX

          HTC has never had a stutter or lag issue with the hardware that was available at the time so why would they need to do this this time around?
          Even from my sensation, it never had any stutter or lag.

          My S2 did and so has every other S model since!

          • sounds legit …


          • Martin Lane

            Nonsense, just Google “htc sensation lag” and you will see you are wrong.

            Lots of users complained about lag.

          • SubX

            Mate, I had 2 Sensations. I still have them! Never had any lag or sutter issues with them. I can’t be “wrong” if I own 2 and have never had any stutter issues now can I?

            Yes for what it was at the time, the Sensation was a beast! Remember though, what was cram pack into that phone for the hardware it was running on.
            I will admit it was not the fastest at opening apps or brower but the interface as a whole did not stutter like the Galaxy S series did and still does!
            Besides that, Both my Sensations now have ViperS on them anyway. They are only used a backups and mp3 players for camping. Also for my son to watch his Chu Chu and KidsCamp videos. Still going strong!

          • Martin Lane

            Who do you think I beleive? the many posts from users online or some random on disque? It’s not you.
            If you’re going to comment on Galaxy S lag you need to be specific, Galaxy S6 doesnt appear to suffer with this based on feedback so far and this is what the M9 is competing with.

      • nebulaoperator

        Thanks for voice-over my thoughts. It all seems very suspicious to me this article follows up as counteracting not long after the overheating issues.

      • We ended with “we need to withhold our judgement until we actually get our hands on the consumer-ready devices.” Look, we’re not saying that the Snapdragon 810 doesn’t overheat or that the M9 doesn’t have a problem. It’s very possible that the consumer product will be throttling heavily and that will affect performance. However, this Tweakers test is hardly relevant for the M9 given the end product will be different.

        • John Kar

          How do you know if the end product will be different? The guy from tweakers said that the embargo date for the M9 was YESTERDAY but got delayed to next Monday due to a boot-loading issue (Though I think the issue is probably down to htc delaying the M9 and not wanting the lackluster reviews to kill-off their sales.)

          If the final software was going to improve the device functionality, they would have explicitly mentioned that the end-product will differ from testing unit to reviewers, like what Samsung did on March 12th regarding battery life improvements in the final version of S6. Instead, htc gave out some irrelevant boot-loading issue problem to try to censor M9 issues as long as possible.

          Sounds to me like the software is pretty much finalized and any new changes won’t affect battery life, processor performance, camera performance, and heating.

          • I can’t comment in detail, but HTC told us that they are working on the software to fix issues raised over the last weeks.

          • Mike Bastable

            See my comment then……

          • I fully agree.

          • le_lutin

            What did samsung do on march 12th regarding battery life improvements in the final version of the s6?

          • John Kar

            They told reviewers that their testing unit will not reflect true battery life of the retail version, but everything else should be the same.

        • John Kar

          As a side note:

          Mr. Petrovan,

          Do you really think htc delaying their embargo lift date right around the time when the M9 got a delay announcement is a mere coincidence?

          If it isn’t a coincidence, there must be something about the M9 that htc isn’t confident about. Otherwise, they would have no qualms letting reviewers release their reviews to the public yesterday.

          • Of course it’s not a coincidence. But that only reinforces our point, which is the software isn’t final. That’s all we’re saying – again, I am pretty sure the Snapdragon 810 is overheating. But HTC still has time to tweak the software. If the M9 overheats in the consumer version, we’ll be first to report it.

          • John Kar

            The “unfinished software” excuse doesn’t hold much weight considering yesterday was the original embargo date, meaning htc was pretty sure the disappointing numbers from tweakers and other Dutch sites were all reflective of end models.

          • SubX

            Go do a search and you will see that HTC is not satisfied with their camera software and are working on bettering it. This is why HTC announced the delay.

          • crutchcorn

            I think you guys did good here. I don’t think that this was a case of anyone being biased on AA’s side. They’re just reporting it how they see it and are approaching something carefully before deciding. Keep up the work Bogdan, and thank you for the update. :)

            (And yes, I am quick to jump on AA’s ass when need be [mind you, not often] – see other comments I’ve made)

          • Thanks, appreciated!

          • crutchcorn

            Any time guys. :) Keep being you eh?

        • mobilemann

          “The report states that these high temperatures were reached only when running the benchmark app. When playing games like Asphalt 8 and Assassin’s Creed: Pirates, the temperature stayed around 42.5 degrees Celsius.”

          why not comment on how this itself is bullshit as well? Freezer benchmarking is lame; this reeks of it.

        • Marty

          Strange that a Qualcomm SoC is having this kind of trouble. Maybe it’s my innate sense of suspicion and distrust, but all of a sudden when HTC is going to make a strong showing this generation, there is no solid SoC for them to gain ground with. Samsung, however, can fall back on its own chips, HTC can’t.

          Makes me think there’s a conspiracy going on between Samsung and Qualcomm. Qualcomm chips have always been top-notch and reliable. Now all of a sudden there’s problems; problems at a very inconvenient time for HTC.

          • Suchir Kavi

            Qualcomm had to switch to x64 prematurely due to the pressure made by the iPhone. This forced them to make a default ARM chip without any of their usual core improvements over ARM’s designs.

  • Mike Bastable

    Tweakers is a extremely reliable site, and they rarely (if ever) publish inaccurate tech info, the tests were carefully executed and it does seems that there are major issues with the handset…whilst LG seems able to handle the overheating issues with the new chipset it seems HTC does not…the problem is big enough to cause them to delay the handset. What you will see is a software solution to a hardware problem, essentially throttling the device. The larger manufacturers are recently pushing more and more money into chip R&D…there is a reason for that! poor quality from existing suppliers.

    • MasterMuffin

      Exactly. And to those that are saying how other phones hit 50° and over: yes internally, but when the whole phone is that temperature, that’s bad.

  • DT

    for me whether it’s true or not me personally I doubt a company would overlook an issue such as that for the sake of a deadline. Hopefully it’s reserved along with the camera software which I believe they will. The phone’s really good and software wise coming from a long time HTC user they’ve gotten better over time so I expect no less than on point this time around. But again time will indeed tell.

  • Geekhound

    Was really looking forward to buy it. Really need to recondider. Waiting for the final review!

  • Nighty

    From what I gathered another relevant piece of info is the fact that the M9 did not shut off when overheating while the other devices would. This supports the theory that a lot of the blame lies on the software not being final as it doesn’t control the device properly. Something which can be found even on PCs. Like many have said, we’ll have to wait till the final release versions to make any true judgement.

    Not to mention the fact that plastic and glass insulate, effectively reducing the surface temp of the other devices (I don’t know by how much but I am guessing it is only by a few degrees). The point is there are more than just one factor to consider in this situation with a pre-release device.

  • Ashwin

    Lol it’s fake coz m8 rise up to 42deg … I think someone payed someone for some favour :P with all poles pointing HTC m9,someone is in a panic.

      Yeah first thing I noticed is that image has been photoshopped excessively to overeggagerate the issue. The picture looks a whole lot worse than the numbers and most won’t even read the numbers.

      Tweakers is a very reputable tech website. They’re like the Dutch Anandtech.

      Also, what polls are those? All the polls I’ve seen have the S6 Edge at 50%, S6 at 25% and M9 at 25%.

      Hell, look at the top of this site and see that both the S6 Edge and S6 are trending above the M9.

      • The-Sailor-Man

        “They’re like the Dutch Anandtech.”

    Wow, Android Authority quote AnandTech , the site of the Apple’s employee – Anand.
    BTW this is the same site who FIRST discover the overheating issue of 810 , but then were expecting Samsung to use 810.
    BTW even Qualcomm said that they will NOT MAKE the next SoC on the same process as 810.

    • Anonymousfella

      Its not about AT being biased. That article was inconclusive as it was based on a thermal reference design platform. It wouldn’t show what happens in real life correctly

  • will

    How did people already do a review on the M9’s battery life? It isn’t even out yet and reviewers haven’t even finished reviewing the phone? So Where are these “facts” coming from?

    • John Kar

      Actually, reviewers have finished their reviews. What you see here is what you’ll get in the final version.

      The embargo was set to lift yesterday, but htc delayed it to next Monday. A few review sites didn’t get the memo, so they ended up releasing their reviews, causing tweakers to release theirs.

  • Alex P.

    You’re trying to blame it on a “non-final software”… Well, the ONLY thing HTC can do in “final” software is throttle down the CPU frequency more aggressively once it reaches certain temperature. Which is also not good because it would obviously limit the maximum performance, and the performance drop might be pretty noticeable (you might see sudden “stuttering”) if you would be playing a resource-intensive game with a lot of on-screen movement when the CPU will start to throttle down.

    Poor HTC, they can’t even get a single flagship device right ;-)

    • SubX

      They got the M7 right and the M8.

      That’s why they are both voted, best phones ever made an also won the most awards!
      Not sold the most. But made the best!

      • nope, M7 plagued with purple tinted camera (making it unusable unless on a broad daylight) and it’s a wide spread issue, not only affects small batch of devices. Dude, did HTC pay you to defend them?? Or is it simply fanboysm?

        • Libertarian42

          I still am using my HTC One m7 and never had that purple tint issue. It was solved and it’s stupid to keep harping on it.

          • it can’t be solved. it’s a hardware issue, the only way to solve it is to replace the camera hardware, even after being replaced, some people still getting it back. if you don’t have the issue, then good for you. I for one love the device, but I couldn’t live with a broken camera, so I get another device. The fact is it affected a lot of people, including me. So my point stands.

          • SubX

            It can be solved and has been solved. As I stated, HTC did a recall (Well here in Aus they did. When I say recall, it was a sensor replacement deal)) and you could send your phone in and have the sensor replaced for free. As i said, they did that with mine. It took 3 days. It is now over 1 year on and still works flawlessly.

            So your wrong! I CAN be solved!

        • SubX

          1 small issue that was easily fixed by HTC. Mine had it too but with the recall, HTC had my camera replaced in 3 days.

          So what… 1 small, fixable issue makes it a fail does it?
          So a company like Toyota releases a car and does a recall due to a faulty sensor and that makes it a fail?
          Use some common sense.
          Yes I am a HTC fan but the same applies to every manufacturer!

  • Hellz

    htc phones spread the heat better than other ones. also, could it be some software tweak that prevents phone from throttling wile running benchmarks to get better results?

    • it’s just too hot, that it spread to the whole body, not to mention it’s made from metal

    • medtza stratospore

      metal can save calorie more, hence prevent throttles.

  • McLaren F1P1

    Let the throttling race start! For me, since sd810 will be better than sd801, I’ll take it as my S2 is starting to feel old as I’ve been using it for more than 3.5 years! If the new flagships unlocked are over $700, I’ll probably go for an M8 or Z2. Tough decision though!

    • Phil


      • McLaren F1P1

        Z3, I don’t think it’s worth it since it’s almost exactly a thinner Z2 with same chip and gpu and costs a good $150 more than Z2 in my country! If it had SD805, imagine the deal and couple that with Adreno 420! Unfortunately only s810 and adreno 330 which is still great, but not worth an extra $150 than the Z2. I also want to try a phone which has an ir blaster and it’s a shame Sony Z2/3 series don’t have one!

        • Phil

          Sorry about the IR blaster but for gaming and multitasking 3G of ram sure helps.

          • McLaren F1P1

            I agree and I consider the Z2 the best flagship of 2014(at least for Q1 and Q2).
            Tough decision if u want to upgrade a smartphone right now! M8/Z2/M9/S6! Wish I could get all of them! I hope G4 or Z4 are mind blowing!

    I still can’t criticize the Snapdragon 810 because I haven’t yet held a device carrying that chip.

    In a month or so we all will see what it’s about, and if it overheats – then we should kick qualcomm’s butt.

    Though the M9 is a huge disappointment in design in my opinion, I don’t think it would be fair to crush it even further. To be honest, would HTC even consider releasing a device getting that hot? I can hardly imagine they haven’t tested the chip thoroughly themselves after all the rumours that circulated about that SoC.

    I am a Belgian guy and I follow Tweakers a lot because it is written in my native language but in this case I think they either got a defective or an early production unit.

    I follow the author in this, to wait and see what the reviews will expose on real end user units.

    But that does not take away the fact some caution is advised. First there are the rumours, second there is Samsung’s choice of dropping Qualcomm for its own SoC (yes, I also believe this is also done from a marketing point than just merely the technical side of things) because of the overheating issues. But third, there are starting to appear more and more issues with the G Flex 2 regarding throttling and those rumours, initially blaming LG’s poor software coding, are starting to head into the direction of the SoC as the main factor of causing this throttling.

    There is no smoke without a fire.

    The tweaks that need to be made are with the camera. I don’t think the overheating issue has anything to do with it. HTC announced the delay before this overheating crap was released so it’s just coincidence.

    Do you think that HTC would release a phone that could “possibly” burn someone, something or even catch on fire? Do you think they a really going to risk another financial disaster by releasing a faulty product that could then have claims made against them?

    Get real now! Think about it before jumping on the so called “testing” of a product that is not even officially released bandwagon.

    These rumors are bad for HTC, and this thing favors Samsung as all other OEM be using SD810.

    I had high expectations when I heard about SD810 but now I am disappointed.. Wondering will Qualcomm be able to compete Samsung chipset in term of performance.

    No matter what I’d be getting M9 most probably will wait for 64GB.

  • I can guess what kind of last minute change that HTC’s doing. FULL THROTTLE the CPU, so it doesn’t overheat like what Xiaomi did to Redmi 1S with Snapdragon 400. Yes it won’t overheat, but you don’t get the performance you paid for.

    So reflections give off heat as well?

      I made an account just to reply to this…. This is an extremely good point!! Touche good sir for spotting what we missed ;)

    Well even though tweakers is one of the best Dutch tech websites, their findings in this matter for now are not facts by far. Anyone who has ever ran an inclomplete android ROM should know that all the problems depicted by them could very well be software related. I for one have experienced major battery drain and heat issues from using Cyanogenmod on my HTC One M7. After installing a different, more stable ROM all those problems vanished. And like said before, HTC is really not in the position of making a huge mistake like this, especially when Samsung’s dominance is still strong and basically the camera in the HTC One M9 might not really be that great. They should know a lot better..

  • TodaysGOP

    Anandtech did use the updated software, which means that HTC throttled the chip down to an acceptable balance of performance and heat. The heat is still there and over time will help the phone degrade.

  • Sathira Katugaha

    Anybody else thought the m9 was merely in nine tails chakra mode? (The pic at 55 degrees)

  • IamDefiler

    Why release the phone to be reviewed if it “was not running even close to final software”? I guess bad news is better than no news.

  • diper07

    Qualcomm you had only one job.. just one job..

    Lol its funny a company which makes stuff like fridge tv microwave laptop + SoC and mobiles beats the company which only makes SoCs.

    Samsung will always be the king. Qualcomm is a sinking ship on which all the Mobile phone maker companies are sitting.

    • Martin Lane

      Agreed, been using Qualcomm since the Galaxy S4 and tried everything upto Snapdragon 805 and you know what they all have in common?

      They all overheat and throttle in less than a minutes., no surprise at all that Snapdragon 810 is even worse.

  • Choda Boy

    So…the Samsung Galaxy Note 4 is the coolest phone available. I already knew that!

  • doublecheese

    This is another thermal camera heating test. I compared HTC One M9 against the Htc Desire Eye. The result is suprising, actually One M9 did not exceed 39.7C and Desire Eye reached almost 42C.

    See it here

    Every reliable and respected tech site are reporting the whole 810 overheating issue as a non issue. I have been in this business for close to 2 decades now and there are sites I trust and sites I don’t. AA are amongst the trusted ones in my book.
    one caveat I will put on that is that you do need to know a little of what is being discussed, its already been mentioned here but some sites (not saying who) will lean one way or another, BUT and this is important, while the summing up and written reporting may in some cases mislead slightly in favour of one maker or another the data provided is good.

  • Ryan Lui

    The HTC One M9 is definitely one of the best Android phones, and smartphone shoppers looing for a new phone would be crazy to not consider it.

  • doublecheese

    As a HTC fan, I have been using all top of the line HTC Phones since 2008 and I can say that the M9 is absolutely brilliant. But the BATTERY LIFE really sucks and the CAMERA is really bad indoors. I just CAN’T take a good picture indoors.
