Yes.
It might be only placebo effect, but browsing with Dolphin Browser HD heated less One X than stock browser. It might have been only a coincidence and I haven't tested enough to reach conclusions. Yet, other users might confirm or infirm this impression.
This can’t be the normally operating temperature range. When my battery temp gets to 55 Deg C it reports the battery state as “overheat”. This can’t be good...
Ever since I used a custom rom my phone doesn't get any where near as hot, must be something with stock.

I played Riptide GP for a while and topped at ~38 Degrees. Even a 40 Minute Google Maps Navigation with attached Car Charger topped @ around 36-37 Degrees. Perfectly fine for me, tho other Games (or Demos) like Glowball which REALLY stress the GPU and CPU due to its graphics demo category heat up the phone to like 43 Degrees.
Other than that, I dont have any problems. I only start up Glowball for a couple of seconds to show off graphics power, not to do anything scientific in there.
EDIT: And what should I say. My standby time is around 26 Degrees when not in my pocket. In my pocket it goes up to 31-32 degrees, but thats normal since the casing kind of absorbs the heat of your body at some point.
When I surf the web for like 30 Minutes, my device never gets hotter than 34-35 degrees, even in comfy warm surroundings (like my flat).
The heat discribed in that article seems a little intense... Maybe there is a faulty batch with heat issues? The One X sure gets warm, but so did my old Galaxy S2 and on top of all, the old Motorola Milestone which became a rough ear heater when doing calls for more than 40 Minutes.
I had a 60 Minute call with my bro 2 days ago, and my One X just got up to 29 degrees... Dunno whats going on there. I always have temperature sensor apps running the first few weeks after I bought a new device.
>>>>“If the phone is in normal use without playing games or calling for long time, the temperature should be around 37°C or 38°C. But if you use your phone to play games or surfing internet for a long time, it will be normal that the temperature rises to around 55°C.“, official statement from HTC. <<<<
This is the one major gripe I have about the One X. It should not heat up to 50C no matter what. It may be "normal" for the One X, but it's not normal or good in general. I hope the next firmware update addresses this. I've gone through god knows how many phones and the heating issue is by far the worst with this phone. Some surfing and apps running for about 10 minutes should not warrant a jump to 40+ degrees in my opinion...
I just bought a Samsung yesterday. Not sure if I can tell if it's warm or hot, but it does give quite a lot of heat. Specifically where it say's Samsung next to the camera and spreads of a bit to the screen and the back. Is that where the Exynos Octa 5420 is located? Anyone mind posting screenshots of how hot their CPU gets? I'd appreciate it so I can compare it with the temperature I get; I'll post my results soon. According to some search results on google though, people some people get that warm feeling.
My Samsung travel adapter that came with the product also heats up, but again, I'm not sure how hot is actually normal. Just a FYI, doesn't burn my fingers or melt the device, just's a bit uncomfortable touching near the very top.

Exchange it. Mine doesn't get hot at all.
I just noticed mine was getting warm near the camera as well before I read this post. I was watching HD YouTube videos full screen though. It's back to normal now.
I exchanged it and it's been a couple of days already; seems like the issue is universal when playing games or having high CPU usage.
Yeah it's normal...it happens to mine as well. As long as the device isn't burning hot, the heatsink is doing it's job. This thing is powerful enough to replace laptops so heat is to be expected.
Anyone know an app that shows CPU temp in a widget? The only app I can find that shows actual CPU temp is Trickster Mod. All the other apps I tried just show battery temp.
I ran AnTuTu benchmark to where it was almost done - 87% after the 3d test - then I looked in Trickster and saw 56 degrees, quickly dropping to 42 deg. The battery started at 30 deg and reached 34.2 during the benchmark and didn't really drop down to 30 degrees after that.
I am a little surprised that there is no CPU temp apps on the market, with fancy graphs and stuff. Come on, devs, we don't care about battery temp. Tap into that CPU sensor, dang it!
Not Hell Yet!

I was in my first meeting using my new Note 10.1 2014 edition and I noticed that it felt warm. I had the previous note 10.1 and never noticed it even getting warm. Is there an app that I use that will give me the temperature to post?
Doc
Same issue here from Spain. Its seems is for every Note.
Be careful, I know someone who broke his Note by playing like for 3 hours to Real Racing 3. The Note was extremly hot and it died. Model was a Black LTE Snapdragon.

Was that a Note 3 that he broke? I was unaware the LTE Note 10.1 (2014) was released yet.
I just got that Real Racing 3 game and was going to play it. I will check my CPU temps after playing for awhile, though it's a little inaccurate since the CPU probably drops a couple degrees in the amount of time it takes to switch to Trickster Mod to check the CPU temp. I wish the FPS Meter screen overlay could show temps, kind of like EVGA Precision does for PC users, or I wish there was a CPU temp graphing application, or any app that keeps a min & max of CPU temp. Unfortunately, there isn't jack out there for CPU temp, but there are tons of apps that do stuff with your BATTERY temp. Who cares about battery?
UPDATE: I'm seeing 69°C and 70°C when playing games like Kingdom Rush & Real Racing 3. A tad on the warm side, but acceptable for me. I do have a case on the tablet, so that might make a little difference. It drops to 50° after about 10 seconds, then eventually down to 39°.
Compared it to my Galaxy S4, but I don't have those games on my S4 so I opened GTA3 & Block Story and checked the temps and saw 62°C. The Note probably gets a little hotter, but this test wasn't that long so take it with a grain of salt.
Well I just got mine today... Its FA44EWM... and its a fireball just like my M7. GSAM was reporting 109F when it was setting up initially. Couldn't even hold the thing.
Reviews said that it doesn't get hot at all so I don't know what's up with it. I'll use it for a few days and report back. Anyone else having temperature issues? I'm afraid its going to fry the camera like the M7 :\
I noticed my m8 got pretty hot when streaming video through the my dji quadcopter app. In normal use it does not seem to have any issues. The aluminum body is supposed to be a great heat sink.
I guess I'll just have to watch it then. I knew it was too good to be true asking for a Qualcomm SoC that doesn't have heat issues... At least its not the Sensation I guess.
I just ran a stability test with Antutu... Its actually not that bad although if it was on the charger, it would be problematic. Topped out at 108F/42C, started at 86F/30C
Other than that, everything is perfect on this phone. Not a single build quality imperfection, great LCD, surprisingly nice camera, and better signal than the M7 had. I don't regret it at all, the heat is just disappointing. My UAG Maverick will be here on Wednesday along with my 32GB microSDHC UHS-I card I got from Amazon for 25 bucks.
.
Mines has no heat issues. Only heats up during intense gaming, benchmarking, and for some reason it heats up when the battery dips below 20% but only to a warm touch except for gaming it heats up tremendously. Even with my screen brightness all the way up it doesn't heat up ridiculously. Overall it's fantastic.. give it a few days or send it back for a replacement.

Same here, I haven't had any heating issues, phone is always cool to the touch.
How odd... it appears to be settling in or something. I just did a run with Brave Frontier (a game which is a great way to overheat your phone) with it plugged into the charger and its at 102F. The One would be at 113F by now and no longer charging as a result. I think I'll watch it for a bit. I seem to remember that my M7 actually hit 119 when I first got it and then settled down to a normal max of 110 with it rarely hitting 113 on the charger.
If Brave Frontier didn't overheat it, nothing will. Brave Frontier actually has a dedicated question in their FAQ for LG G2s overheating and its overheated my Nexus 7 before and crashed more than once as a result so this is actually kind of impressive. I'll report back as I use the device.

I've seen 11x degrees while charging, streaming google play music, using the GPS, and running ingress all with the phone mounted on a sunny dashboard. My device is my car infotainment system so it gets used heavily in the car. It doesn't always get that warm but definitely warm to the touch. Eliminate a few of those things and it will cool down but I would still call it warm when playing a game. Unless someone tells you exactly what they're doing with the device you should take temperature reports with a grain of salt. There are a lot of variables and unless you make them the same you can't compare two different usage patterns. I'm guessing it would stay cooler if you kept the CPU and GPU underclocked but if you run them at their specified clock speeds the device will heat up. Simply checking e-mail or web browsing will keep my device cool to the touch as well.
when using wifi/4g in my house, i watched video, browsed fb and even shared internet and all. below i'll give my observations:
in wifi:
watching video, fb and browsing, whatsappin: the phone get very very slightly warm like not warm just the bit different from the phones usual temp like it hovers around 33-34.
when gaming in wifi it goes arounf 36-39 (NOVA 3) battery never crossed 31..
4g in my house, battery arounf 32-33, temperature around 37-39 for all.
but when i step out of my house, like when i'm operating my mobile in train/bus and the ambient temperature varies from say 28-32, my phone gets considerably hot and today, i was travelling in Bus and the ambient temp was around 35 and i was just browsing , watching videos and fb, my phone became hot like it even would have touched 43-46! i felt it hot to touch, is this norma(it's making me extremely paranoid)l!!??? if this is the case what happens if it's summer here, the phone would become blazingly hot, coz in summer ambient temp would be around 36-44 and all!!
Is this normala or am i unlucky for the second time ? I'm getting paranoid!
Just hit them back up

Are you serious.... When the ambient temp is 35 degree what else would you expect... Every phone on the planet will get that temperature. Can't believe you had a phone returned for this. You know the front of the device is black and absorbs light... When the sun hits your phone it's gonna heat up also. This phone is the best Android phone when it comes to thermal throttling.

With heavy multitasking, I hit 60+. Not regularly, but it has happened. The temperatures you're hitting are normal for me. I've had zero issues with the device. I have an OtterBox case, so I don't feel the heat as much. Honestly, I barely even notice heat at those temperatures. Considering the fact that the body of the device is aluminum, it's going to easily get hot to the touch.
Also, my One would almost always run between 45-70, and I've had that since launch. Used it heavily daily for years, and I still use it regularly as an app development device. No issues.
These devices have extremely powerful processors. They get hot. There's not an easy, efficient, way to cool a processor in a device like this yet, but they're designed for heavy use, so I wouldn't worry about it.

Hi first of all thanks for the reply.. I'll tell you what really made me paranoid.. Every evening I travel in bus and train and the ambient temperature would be from27-28_29.. I use 4g jio.. I just browsw/fb/insta.. In minutes my phone near the earpiece on the screen gets warmed up and it'd go around 40-41. Then I lock it it cools down fast but when I unlock it in seconds again starts warming up... My friend using same 4g in moto g4plus but his screen is cooler than mine... Please my one last doubt...
This is nothing lol. I live in Scotland so just now ambient temperature range from 5-13 °c and in my house 21-23°c and my Z3+ hits 60-70°c easily on heavy use. Benchmarked it one day and hit 90°c. The joys of the 810 chipset. Anyway away to upgrade to the OP3T so i should see and feel a massive difference.

Install a custom ROM and kernel and limit your background tasks. You may just have a bunch of things running using your CPU.
Thank you all!
Hey all thank you guys very much for replying to my thread! i'm really feeling okay instead of getting paranoid with my phone.. although i'd be very happy if you guys just clear me this last doubt!
today I was playing NOVA 3 connected to wifi in an ambient temperature of 25C, 5-10mins into gaming, CPU reaCHED A MAX OF 41c and at around 20 it maintaining at 43 but jumping sometimes 45.. this is gaming, but i get the same temperature just browsing in knda same ambient temp while I'm travelling. and also browsing in wifi/4g(fb,insta,chrome) in my house in ambient 25-27 gets the phone phone to 35-37... and the rest of the pat of the mobile is cool, even the back side is normal, only the small portion between the earpiece..
why is this happening? is this normal(it'd be great if you guys clear this)? if yup y so? and why phones like oneplus x and moto g4 etc have relatively less temp than OP3..
I know it'd be irritating to answer kinda same question again, but this would my help paranoiac freaking out for my mobile will go down..
thanks in advance for your replies

Because the Oneplus 3 is a lot faster, the Temps you are giving are n even close to hot... This has been one of the cooler phones so far.
Like others said, those temps are completely normal. Hell, I'd even expect them to be higher with your fairly high ambient temps.
About comparison with other phones - it all depends on internals and design. OP3 is made of aluminum so it'll dissipate more heat into the case - you'll feel it better. Other mentioned phones are plastic, so they'll contain more heat inside (you'll not feel so much heat, but the cpu may even run hotter).
And OP3 has cpu located just below the camera, so it's normal that it reaches top temps in that upper center part of the device.
P.S.: You talked about loads and ambient temps, but didn't mention screen brightness - that also plays a massive role in running temperatures.

for me mostly brightness bar will be in the middle... i never use it with high brightness..
Just get a case and maybe a screen protector so that you can't feel it getting hot.

hey ya !! sorry to disturb you again and again.. just a urios doubt.. what'd be the temperature of the phone or how hot can it gets, when u use 4g and fb app in ambient temperature of 29C and 33C..
mine got arounf 38-41 for the 1st cse and around 43 for the second case..
I know i'm being paranoid, ,but please, clearing tis would help stop worrying a bit
All the temps you posted are normal
About Moto g, it has much weaker SoC. A Ferrari's engine gets much more hotter than a toy car. Doesn't mean there is anything wrong with Ferrari
4G /3G active usage can get hotter than gaming. That's also normal

Nothing much to worry here. Even I use Jio all the time. My OP3 get a lot hotter than any other device I use before. Reasons I knew are these.
1. OP3 rock with a high end processor. Say SD 820. Other phones you mentioned are consisting of relatively lower end processor. So internally they might heat up more that OP3 while doing high processor intensive tasks, but the plastic casing keep the heat inside, as OP3 is made up of Aluminum that being a metal heats up so quickly and and u feel more hotter in hands than the other ones and also it cools faster.
2. AFAIK the processor is situated just below the Camera bump. Hence it heats up very quickly at that area. Irrespective of outside temperature.
3.While using 4G network it's obvious that the phonehave to communicate with the network at a very high rate than 2G or WiFi. So it's clear that it will heat up. Also using high processor intensive application like Facebook gives the processor high stress and it heats up in no time.
Remedies
1. Use a case. That somewhat helps in insulating the heat.
2.If possible use WiFi rather than 4G network. That will considerably helps your battery life.
Conclusion.
Don't worry about the warmth of the phone.Its normal. Just enjoy using the phone.
Never Settle.
Cheers.
Clearly never experienced a SD810 device. I'm sure Snapdragon took there name too seriously with that chipset. I could hit HIGH 80°c in seconds playing basic games, using the camera and under heavy usage. Had to tailer my use around my Z3+ but now I have the 3T I can do what I want and it never goes past 50°c so far.
Some phones are great to take camping because if you play Asphalt 8 long enough, the back warms up to the ideal temperature that can bake bread. Rate this thread to express the extent to which the Sony Xperia XZ Premium stays cool under extended heavy use. A higher rating indicates that even when playing strenuous games for long periods of time, the phone doesn't get uncomfortably warm.
Then, drop a comment if you have anything to add!
Mine has not yet heated at all! I have used Zarchiver to zip and unzip, several large games (modern combat 5, order and chaos 2 etc). Even in direct sunlight, the phone only became luke warm!
same story...this phone remains cold. in every condition.
for me it it the coolest phone i have ever had
I live in a tropical country, so the ambient temp is high most of the time. Despite that, my phone only gets really warm, but not too hot. Very impressed with the thermal management on this phone.
I just got back from Mexico. Jumped in the pool and didn't realize I left my phone sitting in the sun. According to GSam Battery Monitor, the temperature of my battery was at 50 degree Celsius and it was only luke warm to the touch. Very impressed. I was scared for my battery tho lol
i play Clash of Clans on my XZP and see the temps getting as high as 106 degrees. It's pretty warm in the back. Not sure how anyone is really able to say theirs is "cool" all the time.
PC is not cool when playing games. Why would be XPERIA XZ Premium cool when playing games?

Because its cpu's tdp is under 5 watts with the integrated gpu while a pc's cpu could easily go over 100 and have additional gpu and other heat inducing components around?
Don't get me wrong, many phones get hot during intensive gaming and that's not a huge minus considering they don't have cooling. Sony's done good job with it and it's on par with other flagships with sd 835 considering it's a pretty efficient chipset. It's just that the comparison you made was out of place.
Mine does get warm sometimes, but that's it. Just warm.
My old G3 used to get really hot near the Power/Volume buttons when gaming or running VR apps.
It's the kind of hot where you notice it, but it doesn't really bother you. Unlike my G3 where I had to move my fingers away from that area.
More importantly, it hasn't stopped an app or lowered the brightness due to heat yet.
Omg 50.7 dc
My phone can get hot doing VR stuff, but otherwise it seems near impossible to get it hot unless it's a very hot day and I'm out in the sun.
Then it's possible to get the camera app to warn about heat, although this has never actually progressed on to the point where the camera shuts down. Not like my Z3 where 10 minutes of photo taking and that was your lot.
The phone is amazing, I manage to record 4k videos more then 30 min and phone didnt need to turn off cus of heat, like on Z5P.

Never had this phone overheat. Even when video calling over 4G.
pretty cool always, can get warm but only warm
in love with it, snapdragon 835 does the trick to prevent overheating.
although when viewing 4k content or in 4k mod it does get hot, but hey which device wouldnt showing 4k? im impressed
i live in Jakarta,Indonesia and my XZP only gets hot when the signal is weak.other than that the device is around 30 celcius to 37 celcius.
Well to add to this conversation , Got this phone and regarding heating it heats for sure in some situations, but not as much as Z3 dual in same situations (my previous phone) and I am not worry about heating as Z3 dual heats a lot when playing pokemon go on sunny days during summer and never had heat warring except playing same game in background while recorded HD video of car crash in front of me, that is only when I got heat warning on Z3. On XZ premium same situation I could feel some higher temperature in hand, but not even close to Z3 , and another worst situation is game pokemon go and mass evolving in game (who knows what is it) it brings Z3 to very high temp, while XZ premium gets up to with temp enough to be able to feel it. Zip large files with password 128 bit encryption or unzipping does not produce any heat on Xperia XZ premium, overall it is very cool phone.
My phone does heat when playing games like Shadowgun Legend and Modern Combat 5 but I didn't notice any throttling.
Mine was hot while i was filming 4k in a 34 degrees outside in the sun.
i simply solved it by dipping the phone in the pool voor 10seconds and it was fine again. made nice videos
