This question is very easy to answer.

The HTC One M9 uses a S810 wich get hot faster than others recent SoCs used in iPhone 6 and S6.

Same thing happens in the LG G Flex 2 and both use heavy throttling to prevent the phone being too warm.

We can discuss why the S810 get warmer than Apple A7 and Exynos 7 but essentially, I think it's because A7 use less core with a lower frequency and Exynos 7 use a 14nm FinFET manufacturing process.
[One (M9) General] MoonRaven:
Please check if there is an update available. The issue should've been fixed.
[One (M9) General] th3:
The M9 has been shown to run hot, even after the thermal throttling "hotfix", pun intended (hotter than its competition). This isn't even disputed anymore.

Why? I don't know, but damn, am I curious.

One suggestion is that they have processor hotspots not being dealt with due to a high localized power density... so while the SoC power is OK, two or more hotspots in a localized area are exacerbating the situation (they quickly make the situation run out of control).

It only take one hotspot to trip the Tjunction profile. The rest of the SoC could be running fine. And this is either a problem with the Thermal Profiling and Cooling Spec (design or data sheet) or the Snapdragon 810 itself.

HTC One M9 - 41.7C

LG G3 - 42.6C

That's not hotter than competition. That's within the comptetion.
[One (M9) General] STANNY08:
I can't help but think it is an issue with some handsets. I've read reviews that state that it isn't an issue and reviews that show some concern.
[One (M9) General] th3:
You chose the hottest one?

If you read the major reviews, they still state it runs very skin warm.

M8, S6 and IP6 are the M9 competition. And upcoming G4. G3 isn't.

[One (M9) General] :
[MENTION=2496746]th3[/MENTION] - yes, because what you said was incorrect. Also, the difference between hottest and coolest is 3.6C. That's not a lot.
[One (M9) General] D15:
The display and the battery performance are also worse.

I think Qualcomm has tried to cover the problem as much as they could but it's very obvious that they have screwed up with this processor, that they're even starting to talk about the "much better much cooler" S815 already.

It's not HTC's problem (nor was it LG's when they tried to pin it on LG earlier), it's the processor. All HTC (or LG) can do is try to cut the load on the processor and basically run it at lower speeds so it doesn't get too hot. Obviously that will impact the performance, but that's all they can do with the software updates. They will just try to find the right balance between temperature and performance.
[One (M9) General] Chocolina:
I was avoiding the S6 because of the Exynos not being favored in the Rom-developing community. But the rumors-turned-facts about the 810 SoC have me worried. Not particularly blaming Qualcomm, but it seemed like this issue has had almost half a year to be ironed out.

I think the most troubling is that I've read the SoC's clock speed has been reduced to lower overheating, and the thing still overheats. So even if you've been waiting nearly 15 months for Snapdragon 810 like me because they said it'd be a beast, its disappointing to know that having the chip run ans intended might melt your phone.

Also even if early reviews are to be taken with a grain of salt, I've been hearing about underclocking, overheating, screen and boomsound quality being a step back from the M8's, and camera being not that great. I'm positive in time they might fix alot of the issues the early releases have been suffering from, but I am not one to wait many months longer for those updates. Just the updates to get a new android version can be grueling, so I can't imagine waiting for an update to make the device finally comfortable to use. With the S6 just a few weaks away, without all the nasty rumors the M9's been having, I just might have to bite the bullet.

The good news, I hear Exynos is naturally better at emulated gaming which is something I always consider when buying a new mobile device. The bad news, it isn't Qualcomm, and I already bought screen protectors and cases for the M9, despite it not being out yet in America

Edit: I take back what I said about getting an S6. I did a search on release date, and it's released in India for $950 for the 32GB model. Unless they can make the 64GB model less than $720 in America, I'm not interested. Which isn't likely. I would have already had a Xiomi Mi Note 4 Pro if the damn thing wasn't impossible to get, and would have got a G Flex 2 if it came with more RAM.
[One (M9) General] th3:
Read the reviews. What you initially suggested is wrong and so is your selective comparison against the worst, non-competitor. It's still running hot, as every major review says. Even though it's not too much hotter, I agree and now acceptable to hold, it's still hotter, and still warm to hold.

For a week I am using this gorgeous handheld, tons of blowing away emotions - no any significant overheat yet.. :(
[One (M9) General] 10rdan:
Correct me if I'm wrong, but if the software updates are, simply, throttling the chip to approx 1.5 it is no better than an m8, which I have ? Plus, Sense 7 will be on m8 "soon", so no need to upgrade.

Sense 7, custom, roms are available now.

NOT having "a go" at HTC, I've had about 7 different handsets in last 5 years.

[One (M9) General] DeadPotato:
Actually I'm having worse battery life in general, do you think color calibration has something to do? Because I tried one of the coolest side yesterday and just got 5 hours SoT, most of the day I was on Wi-Fi. Should I do a factory reset?
[One (M9) General] jeroenpico:
Since the 1.40.401.8 update I got last week my phone is getting quite hot more often... Also battery life seems to be worse compared to before the update, though most people report improvements...

[One (M9) General] DeadPotato:
Give it a couple cycles to settle, I was reporting lower battery life right now I have 4:16 hours SoT and 38% left. If doesn't improve then you could try a factory reset

[One (M9) General] sausje85:
With these hot temps here in Europe (~38), it's not managing to stay cool.. even the lightest of app using or whatever usage already heats it up to 40++. Even just idle in my pants i could feel the hot back plate against my leg.... Getting kinda concerned with these temps... Just 5-10min of apping would already bump it up to 48 degrees :\

Disabled the second CPU (last 4 cores) for now, temps seem more manageable..
[One (M9) General] DeadPotato:
That's the bad thing of a metal phone, temp gets affected by external temperatures more than other materials. In my country 30 Celsius is hot lol and after some usage and app switching, even after using camera phone has never passed 40 degrees. How are other phones like the S6 or the Z3+ behaving with such temperatures?
[One (M9) General] davidtm0:

44°C using a fast charger ...

[One (M9) General] muayyadf1:
Normal. Only thing makes people worried is the metal body that acts like a heatsink. Other phones heat as much or MORE but material used isolates the heat from being felt.

[One (M9) General] DeadPotato:
If you have that problem while gaming then it's normal and it's not a problem at all, if the heat is uncomfortable for you to hold try a holder or, if the games you play are worth it, use an USB paired game pad and the problem is solved.
[One (M9) General] shivadow:
It was while navigating for about 30 miles but the last thing you expect is first degree burns when you pick up the phone and HAVE to carry it with you.

I wouldn't be so certain that a case would help. Yes it may make the device easier to handle yet would it add to the issue of heat radiation, not allowing the air to cool the device effectively?

Look at flars kernel thread, with his kernel you can use six-core mode or just underclock the two Clusters by a tiny bit and the overheating issues are gone.

I'm already using power save mode which switches off 4 cores and reduces the other 4. It's a standard feature on the stock rom.

Lets just face it. Overheating is a htc trademark.

[One (M9) General] DeadPotato:
There are plenty of reasons why turn all of the 4 A57 cores is a big mistake and it doesn't helps, but increase heating. But to make it brief if you remove the big from a little.big architecture you are over loading the charge of the weak cluster. I've navigated with Waze for 15-20 minutes with temperatures not higher than 42 Celsius, which was not uncomfortable to hold or causing burns, but I'm using ElementalX with a custom ROM.
[One (M9) General] jaaystott:
So, in response to software update, on taking the device out of the box on around the 19th there was a 200MB OTA. That OTA was installed before ANY observations were made about heat. So what I can say is, before the update this heat issue may have been worse than it now is. However, there is still an issue, and throttling the device is not a resoloution, thats a soft-fix.

It's a shame, but having spent a few more days with this device I just don't know if I can trust it and that worries me.

And they should skip the benchmark detection and let the CPU run in the real clockrate too.

Running the Anatutu thing, same deal.. It gets warm enough for you to notice, thats about it.
[One (M9) General] D15:
There is nothing wrong with the reviews. You're just using the newer version of their software where they underclocked the processor. It still gets hotter with antutu though because of HTC's cheating code which raises the processor's limits to boost results.
[One (M9) General] EndoSurf:
Except it doesnt get any hotter then when playing games, regardless of the "cheat"

These reviews try to flog the absolute bejesus out of the phone, of course its going to get hot. Thats what processors do when you flog em.

Real world is different story.

I never used an M8 so can't compare. But from the M7, its not as hot and its a hell of a lot snappier.
[One (M9) General] D15:
Do you know how the cheat code works? The cheat code only boosts the processor speed when you're running a well-known benchmarks app (like antutu) to boost numerical results, not when you're running games.

The reviews were accurate, but they they were done on the device before the latest update (which underclocked the processor). Even HTC acknowledged the overheating issue.
[One (M9) General] w1000i:
cheating or not, underclocked or overclocked !!

M9 is super fast in both games and UI experience better than any phone out there. :cool:

I hoped that 810 was good for battery but still it's okay

[One (M9) General] EndoSurf:
Yes i know how it works.

And what I am saying is.

MY

M9 didnt get any hotter running Antutu then it did playing Trials frontier for 20-30minutes.

So if the "cheat" does what it is supposed too, then the thermal restrictions were removed and my phone should have got blazingly hot.. It didnt.
[One (M9) General] tmac31:
cheat just unlocks frequencies over 1.6 ghz but phone still throttle very early to prevent heat.

It matters little what your subjective opinion of "hot" is, several sites have empirically measured it in standardized environments and the results speak for themselves.

[One (M9) General] D15:
As I said a few times already, it's not as blazingly hot because they underclocked the processor with the latest update. Tests have shown that after the update the M9 still gets warm when antutu is run but only reaches 45 C rather than the 55 C it reached before the update. However, the performance score took a hit compared to before the update.

Manual M8 vs manual M9 camera, and battery... can't wait.
[One (M9) General] hung2900:
Not sure about fastest, but surely very fast and smooth. I was bother by how HTC fooled customers when cheating in M8's benchmark, but the performance was blazing fast and battery was decent when I used it. Only the camera was the downside for me (M8).

P/s: I'm quite sure M9 can't be as fast as S6. UFS-2 giving an edge far away from competitors. But battery life seems worse than M9, and without battery interchangeable and microSD slot, I don't think I will buy it. The Egde maybe, cuz it gives the feeling of difference.

I too am with Adam on the Match 31st delivery date. Can't wait. Although I couldn't help but notice that my available bank balance has gone up since last week and there's no trace of the upfront cost I paid mobilephonesdirect on my statement, order tracking on their website still says awaiting device release so I'm sure it's all good!

I will be using the M9 as my daily driver for a week or two. That's when I'll be comparing.

I don't really like synthetic benchmarks... Good to show technology, but not for user experience.

And all that matters to me is user experience although I too want cutting edge technology.

I would do a review but I have a huge lack of time, and after spending so much, I don't see it being appreciated even a tad. I think all we really need to know is out there in reviews.
