hello all.. I just wanted to understand how z5 compact cpu Temps are under normal usage (basic phone usage messaging, youtube video, basic camera usage, browsing and reading articles).. for example my oneplus one running on snapdragon 801 typically hovers between 33-38 for majority of the tasks.. I understand no phone is the same.. different people have different experiences...Through this thread I would like draw some patterns and conclusions.. thanks!
Just installed a cpu temperature monitoring app to check.(cpu temperature by mooncakes from playstore)
From what I can see (if it shows the correct sensor) it hovers between 28 - 33.
Using a "regular" Z5, though.
While browsing/messaging/youtube for prolonged periods I am usually at around 35-40c.
Gaming with 2d usually stays at around 40c and 3d is at around 50c.
Installing and updating apps usually generates most heat with temps of around 50c+ but fortunately its not something that happens often.

Maybe u could add which app you use, I edited my post too.
Also, I think while shooting 4k video and using the AR effects for prolonged time the temp wil go above 50°c (I'll have to test) but the sd810 probably handles more.
At my old Z running a snapdragon s4 pro shutdown temperatures are around 78°c or so.
thanks guyz.. again.. just to clarify.. we can exclude the extreme cases.. like shooting 4k and prolonged gaming.. these are known to stress the cpu.. I am curious to understand how bad it is during normal usage.. hopefully this will allow others to make informed decisions.. I have mine coming tomorrow!

Well, under normal conditions nothing to worry about. (in my opinion not even under heavy load, Z5 is supplied with a dual heatpipe - but that you'll probably already noticed lol)

z5c doesn't have the heat pipe based cooling.. hence the worry

Then I understand
only the z5 and z5p have the heat pipes.. z5c doesn't unfortunately.

I'm using the Cputemp app which has a cool option that adds the cpu temperature to the header of the phone (where the time and battery life reside) so the temperature is constantly under check.
I'll add also that battery temperature is usually at around 30-35c and if you're doing something heavy for a long while it will rise to 40-43c

What **** are you talking? It has, for gods sake.
Premium has dual heat pipes as rest has only single i guess.
My temps are between +17 - +38 last 5 days (no gaming)
Idle temp at night usually +20 or little bit under.
Web browsing get temp usually up to +35

No, all 3 models have dual-heatpipes. Seriously, what the **** is up with you guys? The last model with 1 heatpipe was Z4.

Don't be like that
guyz.. easy.. let's keep the discussion civil... its okay... if a person is right or wrong.. there is absolutely no need for cursing.. I went through https://www.ifixit.com/Teardown/Sony+Xperia+Z5C+Teardown/53206 and there is no sign of it.. you can look at z5 or z5p on the other hand and you'll find it.
check out step 12 through 14.. https://www.ifixit.com/Teardown/Sony+Xperia+Z5+Teardown/52300.. this one uses it.
I already posted it in a an thread, but here it seems more relevant.
I made a small video showing my Xperia z5 compact overheating.
Just with browsing the CPU can reach temperatures of 50 - 60° in 7 minutes.
This happens while browzing at other sites too. CPU throttles bit by bit and it gets really warm.
This makes the back of the phone very very uncomfortable to hold and i can't imaging how hot it will get in the summer or under the sun.
Can you please give me a feedback on that because I am thinking of returning it.
There is something wrong with the cpu temp app that you are using..I just tested two apps simultaneously on my oneplus one...The app you used reported 46C while the "cooler master" app reported 33.3c attached is the screenshot!
There is no way my phone was at 46 because..the phone pretty cool..So I suspect the app is not reporting it right...not sure where it's getting the info from.
https://www.dropbox.com/s/3iq8arqy5fcupex/Screenshot_2015-12-21-14-25-10.png?dl=0
Okay.....I performed extensive testing in the past two days regarding the temps to understand the behavior....Here are the details..
I used my old oneplusone and z5 compact to compare 1. perceived heat (based on touching the device) and 2. actual temp readings from the app devcheck pro.
Regarding temp readings, I monitored both CPU as well as battery temps. I generally felt, the "perceived heat" comes into play only once battery heats up as this lines up along the back of the phone.
Test performed: Used flipboard and news republic apps for 5-6minutes. Then opened chrome dev browser app and loaded "cricinfo.com" website. This web-page is flash intensive and has tons of content. I kept repeatedly navigating through the webpages and accessing links. The idea was to perform intensive web-browsing.
Note that both phones had TPU cases on them.
Here are my findings:
-Both the phone's CPUs start off at 37-40c and gradually hit 55-65c. Interestingly, I noticed that oneplus one at times hit almost 73-75c!! whereas z5c never hit this limit (perhaps due to thermal throttling???).
-The battery temps steadily rose from 27c to 38-40c.
Attached is a screenshot for your reference.
-On both phones, the temps rose almost around the same time (about 7-10mins into the test). I felt at some-point z5c was being throttled to maintain temp thresholds. However, I did not notice any "visible" performance drops.
The key thing to note: The back of the oneplus one was slightly warm. Whereas z5c was pretty warm (although not uncomfortable). I think this is exactly where the user gets worried, thinking the phone is overheating. The problem is the glass back as opposed to the padded material of the oneplus one. The glass surface of z5c almost immediately starts conducting heat and quickly heats up.
After letting the phones cool, almost within 10minutes, both the phone temps dropped pretty quickly.

Ok, I searched the forum about this topic and didn't really find anything answering my questions. I'm currently coming from a Droid RAZR and it ran hot to say the least. I can't get a straight answer on this phone's operating temperatures and I'm trying to determine whether to put a thick case on or not(with almost no bezel, I'm paranoid it will break on first drop). From what I've read, about 60% of people aren't reporting very much heat. The other 40% say there is a huge problem and most have had to replace their phones thinking it was a defect.
When it came to my RAZR, at rest with a case on, battery temperature would sit at just under 87 F. Under heavy use, I've hit over 124 F. Without a case, 83 F, the highest I've hit is just under 117 F. Extremely significant when you can't remove the battery and swap it out. I believe that it led to it's premature failure. I want to avoid that with this phone.
Is anybody keeping track of their phone and battery temperatures?
What apps and/or widgits do you use?
What is the normal at rest temperature?
What is the heavy use temperature?
Thanks everyone. My phone gets here in a few days and I want to be ready with a case.
I don't keep track of it. However this phone does get really hot (uncomfortable to hold) when playing games. With Tpu cases this was less noticeable. But lately I installed skinomi stickers for back protector, and it always bother me when it gets hot this way.
That being said, normal uses such as Internet, music, YouTube, xda, camera.... The phone only becomes slightly warm.

I keep wondering why no one makes cases that help dissipate heat, for how hot modern phones get! If anything, most cases insulate the phone and make them get even hotter!

Admittedly, I'm not a gamer but the only times I've felt the device get hot enough to register with the Incipio Feather case were: 1) after a wipe/flash, and all my apps were downloading again from the Play Store and 2) when wiping and the device was plugged into the wall charger (CPU temp was around 100 degrees) - other than these 2 instances, I've never felt heat thru my Feather case.

The case I had been using with the RAZR was a TPU hybrid. I also went to a skin because of the heat. I don't think I cando that with this phone. I'm too clumsy.

I was actually looking at getting the dual pro. Thanks for the feedback. Exactly the type I'm looking for.
Honestly i just replaced my phone due to overheating issues. It would literally shut down or restart just running the camera for too long. After reading some other reports in the forums I decided to send it in and get a replacement. My new one came in yesterday and absolutely no overheating issues. Even can run antutu without a reboot (my other G2 would reboot about 14% in). So from my experience there was a batch that had some thermal issues... I got mine the first day it came out. Loving this second one

Does anybody know if we can track manufacture/release date using the serial numbers?
I am using this case full time: http://goo.gl/0u05G5
I use Battery and CPU-Z to check battery temps. Even with over an hour of straight gaming, I have yet to see it get above 98F. I constanty run the screen at 80% brightness as well, as that can be a contributing factor. The games I have played this long with are Riptide GP and Madden 25.
You really cant feel any heat through this case, and hand temps are too subjective anyway.

yeah, especially while gaming.. and it's not the battery drain that concerns me, the heat is ridiculous for long term gaming..
and slapping a case would be good for your hand but not for your phone
plus there's not one manufacturer that make cases for heavy gaming yet..
i wonder what the case would look like if it was made for dissapating heat.. probably has a lot of thermal pipelines built in that would be awesome..

One thing I've noticed from people's screenshots is that the screen doesn't use that much battery. My RAZR would sometimes draw 46%. I'm sure that also contributed to the heat. smh.

I'm currently in the design step of a case that uses tubing to disperse heat at the top corners of the phone to cool it down and keep heat away from the hand.
If you'd like to give input shoot me a pm and we can discuss it further.
OnT: I very rarely pass 24c on mine, then again I never game on my phone either. Highest I've hit was 42c during some testing.

Are you guys talking about battery temps or cpu temps?
Get the app CpuTemp from play store, it overlays cpu temp while you're doing whatever, enable only the top two options, enable overlay and start on boot.
Then get stability test app and run the first option at top, classic test.
Then report back here with your temp after you do the stress test for about 27 seconds. I hit 66c after 27 seconds.
Curious to see what everyone else hits.

My G2 gets also around 55°C when using the phone normally (youtube, browser, etc.) and over 67-68°C while gaming. I think this is normal for a high frequency 4 cores CPU. Right?
Hey, I received my LG G2 yesterday and i've been experiencing cpu temperatures of:
42-48C being idle
52-59C during browsing, facebook, viber etc
62-64C when on youtube (after the first 5 seconds)
65C when on gps
As for the stress test after 1:20 and up to 20:00 it was around 72-74 C
The phone feels hot all the time though with no apparent reason.
Screen brightness is set to 30% all the time, 3g connection is off and I only keep Wi-fi on. I even tried turning off features like gestures, I don't know if it is of any relevance.
Of course I haven't trying gaming yet, since I'm not really interested in it, but I want my smartphone to be functional without burning up.
Should I return it and ask for a replacement? Or is it an issue with LG G2 or Snapdragon 800 generally? Will it be a waste of time?
Hi, I have been using the phone for the past 2 days and realised that it heats up pretty quickly. It was particularly hot at the top part of the back of the phone, the area where the NFC logo is located. I did several "tests" to see how fast it heats up, and I made sure that the phone was cooled down before each try.
Firstly, I used the phone for browsing the internet for about 15mins and realised that the temperature(battery) has risen to 43 degrees celsius. Next, I tried using its camera and took several shots and after about 5 minutes of use, the temperature has also risen to 44.2 degrees and the a message was prompted stating something like "the temperature is too high! camera needs to turn off." I then tested the video recording in 4K resolution. The recording lasted for only about 3mins 40secs before the message was prompted, and the recording was not saved. The temperature rose to 44.5 degree celsius.
I understand that the automatic shut off of the camera was to prevent any hardware damage from the high temperature. However 15 mins of browsing and less than 5 minutes of 4k recording does not appear satisfactory from a user's point of view, especially after the device being touted as the best Sony has built. I hope that a software update can help mitigate this issue, as it will be a huge hindrance to the day to day usage if the issue remains. Does anyone else have the same issue?
Just own it only 1 day and I have no heat problem. A bit hotter when using under direct sunlight with 3G in about 1-2 hours. Totally no heat problem . Mine always under 40°.

Could it be due to some background processes like media server? First time I booted the phone, I took only 2 pictures when the phone complained it's too hot, and indeed it felt very hot to the touch. Subsequently I don't have this issue anymore.

What's the ambient temperature when you run the tests? Where do you live? Could you record a video to demonstrate what you're seeing? It's strange you're the only one to have mentioned it so far.

Well i got to tell you that all snapdragon 800 SOC heat up doesent matter the phone producer,i have an lg g2 and it heats up relativley quick its not a defect its a must because its a 2.3 ghz clock not a 1.0 so every time u do demanding tasks the proc will heat up you cant do anyting about it,you can try to change it maybe you got a faulty one but keep in mind if you get a new one it will heat up non the less depending on task.
And another thing when battery temp shows 40`C the CPU temp will be like 70`C+<<
Check this out! 38 degrees Celsius! Is that normal for the Z2? The m8 is only in the 28-30 dergees Celsius range.
And here are some m8 different user sceen shots...as you can see the temperature is pretty stable, between 28-31 degrees celsius, a bit lower than the Z2's 38 degrees. I wonder why this difference in temperature between the two?

Do you know the ambient temperatues of where the two phones are being used? Taiwan and Singapore where the Z2 is released are hot countries. The M8 has been released world wide.
If the M8 is from the UK where the temperature is less than 20C and the Z2 is in Singapore where it is ~35C, its going to be much easier for the Z2 to heat up.
I'm sure the Aluminium shell of the M8 also helps with heat.

Or maybe its because of the waterproofing on the z2 wich is sealed up and has no open gaps through heat can emanate and cool down.

Yes it could be, but that is speculation, although I'm sure the M8 doesn't have air circulation inside either.
I think some of the difference could be down to environmental factors.
Ambient temperature is the key thing here. Battery temp means nothing without an ambient temp. My one X, which is my second, they both get around 50 degrees when under load. It's normal. 40 degrees is absolutely fine, it slightly warmer than body temperature. Lol
No one cares about Battery temperature!
Battery temperature won't go over 45°C Anyway!
Check out the SoC temperature! that can reach up to 75°C
Does Xposed work for Z2 ? There is a cool module called "CPU( or SoC) Temperature in Status bar" It does exactly that! Got that on my Xperia Z and it shows me always how hot the phone really is.
Oh boy not the same crap from Z1, the overheating problem & camera shutting itself off because of that, was the main reason I skipped on Z1, Now it's the same with Z2? bummer
anyway this is what I read today from sony:
"We are aware of some users encountering issues when shooting 4K video for extended periods. Shooting movies in high quality 4K resolution can make significant demands on your phone's processor and battery life, as well as phone memory. Therefore for the best experience, we recommend you install a high capacity SD card (Xperia Z2 can take a card up to 128GB) and shoot 4K video in short bursts of no longer than a few minutes at a time." -Sony Mobile Singapore
Wow didn't notice this. There is indeed a High Temperature Warning after recording 4K for about 3 minutes and the camera shuts off. Thankfully, 4K isn't that popular yet and there are no issues recording at 1080p.I hope Sony finds a solution soon because that 4K feature is really advertised.

We all know why LG choose 808 over 810, now let's see the results of their choice:
Here we'll talk about the G4 operating temperature.
Try to indicate your ambient temperature, model, display brightness, app(s) used, your cpu utilization (I use cool Tool for it), and of course temperature (for that purpose I use Cpu Temp wich basically reads bms sensor of Cpu-z in overlay, and Cpu-z itself) ;
Remember to distinguish battery temperature from cpu sensors temperature and if using cpuz remember that temperatures are very sensitive to time so measure it only while performing the task wanted.
Keep it as scientific as possible
*I forgot to mention that CpuZ has an erroneous C to F conversion. So keep it in °C to be accurate
There is an intersting heat comparison HERE on Android Central to begin with
Good idea. Do note that CPU-Z seems to have a bug where it converts temperatures incorrectly from C into F, in the Thermal tab. From what I've seen, CPU-Z should be set to display in C, not F, if you want accurate readings.
To see the issue, check the temps, including in the Battery tab, then in the Thermal tab. For me, in C, the Thermal tab numbers seem reasonable, and the "battery" line in Thermal is close to the temp shown in the Battery tab. But change the units to F, and the Thermal tab suddenly reads the battery, and everything else, too-high by about 30F. The temperatures are not converting properly from C to F, the displayed C and F values are not equivalent. This conversion issue appears using CPU-Z on my last phone, as well.
So if posting CPU-Z temps from the Thermal tab, I'd suggest setting it to C, not F.
Thanks, I forgot to mention it, added
What's the point of this thread? This isn't a PC, it's not like we can do anything about the temps.

That is where you are wrong. It's called we can hard mod the phone for better temps.
Total newbie question, is the temperature you're feeling on the hand the one from the CPU, or the one from the battery, which is closer to the hand?

It should be the battery because I notice my phone getting warm pretty often and I have a widget for battery temperature which tends to go up to around 38 °C often. I didn't check CPU temperatures but I don't think the CPU is heating up too much.
82 F - sitting on the desk doing nothing but looking pretty. VZW, brightness at 0% and Auto.
All these freaking temperature problems will be resolved in a few months when the freezing winter arrive xdddddddddddddf

Lol, no, you can't.
At least LG choosing 808 instead of 810 due to hear issue was the right choice.
https://youtu.be/HltGLYZLySs
Take a look at a link above, SD810 might have upper hands during cooled state but that changes quickly throttling down below SD808 specs. SD810 potentials are pretty much obsolete and probably will never run on full more than 5 minutes.
SD808 is holding its speed even running hot. So I wouldn't really worry about hear part for this phone. But I'm with some users here. Few software updates will iron out some heating problems.

I've noticed that phone is getting hot when charging even if the phone is in standby. I'm getting around 40-44c.

That's low for charging honestly if your referring to cpu temp. Most phone cpu temps stay around 25-35 idling and mid 40s when just doing simple scrolling and small tasks. 60-70c is fairly normal on heavier tasks and games. Kernels usually don't even start throttling until the cpu gets in the70-80c (generally most start shutting down cores at 80).
That being said, my G4 is one of the coolest running phones that I've messed around with. CPU-Z usually says that I'm in the low 40s even on some heavier tasks. I know that my Note 4 gets much warmer, much faster. Heavy web browsing for example will have my N4 in the upper 50s low 60s. The G4 stays pretty stable in the upper 40s low 50s. I'm happy they chose the processor that they did honestly. Stays pretty cool compared to the competition.
you can even mine cryptocurrency on this beast for hours on a normal (here normal) 27-30°C ambient temperature, and the battery gets to 44°C and the CPU gets into the 50s.
This phone has one of the BEST thermal management I've ever seen. I was a nexus 4 user, so you can see how much i was struggling.

I don't pretend to be rude, but that information is outdated and inaccurate. I don't know how the other manufacturers are doing with the 810 to be honest, the Z3+ is sort of new and I've been checking the threads but there's too early to judge so far, it happens that I do have an HTC One M9 up to date, stock and unrooted and I've noticed several improvements through updates. Considering my daily usage I didn't feel this was matching with what I experience in real life, so I decided to redo the test on the video. I ran AnTuTu benchmark 64 bits version 4 times in a row, and left an average of a minute (sometimes less, once was a bit more cause I took the wrong screenshot) between tests. The attachments were uploaded in chronological order, you can also guide for the hour displayed from the device.
Now besides the video only runs 4 times, I did notice it was holding every couple of tests and then decreases, so I decided to run one more for the sake of pure testing and check throttling behavior, and surprisingly the fifth run gave me an increase on the score instead of lowering it further.
I didn't find a dedicated benchmark thread on the G4 forum, unless LG had improved a lot the 808, and based on the several benchmark results you'll find across the internet, including the ones in that video, looks like even throttling snapdragon 810 holds as an 808 in worst case scenario.
About heating problems, if I'm providing a success case scenario with a more troublesome chip like the 810 is, I'm completely sure the 808 will be fixed in time
phone gets crazy hot when running Periscope
it even shows that hot temp message / stops charging
try broadcasting for 5 mins
Intersting comparison between M9, S6, G4, Droid Turbo heat dissipation HERE
Periscope heats up the phone like crazy!
I too have had issues with the device getting very hot on the top half of the screen. Tried a couple of factory resets but it didn't help. Even reset one more time and kept it stock after a few hours same problem. Took it to the AT&T store and of course it was behaving fine. Luckily the rep knew me and accepted I knew what I was talking about. Swapping mine for one first thing this morning when their new shipment comes in. Will update if issue persists or not.
Wish I would have done it 3 days ago. Might have been snagged another battery and leather case lol.

As I am still undecided wether to buy the Z5 or look for another option, I'd like to get your personal opinions concerning the heat emission of Sonys newest device.
I have my Xperia Z for 2.5 years now and in my opinion, that phone gets pretty warm too (I play a lot of Hearthstone on my phone) but it isn't getting too hot to handle. I'd hate to look for another option since my Xperia Z was updated from 4.1.2 to 5.1.1 and my hope is, Sony keeps on updating all of its Xperia phones for at least 2 years.
To cut things short: please state which phone you used beforehand and give a number between 1 to 10 how warm you personally think the Z5 gets, 1 being cool and 10 being unbearably hot.
Ive had the Z1 and Z2
Z1 heavy use 3
Z2 heavy use 5
Z5 Heavy use 8
Nexus 5 - 3
iPhone 6 - 2
Xperia Z5 - 8
On my Xperia Z5 i downloaded the game Heroes Charge and when i started the game i got promted to do an update of 200mb. During the time the game downloaded the update on 200mb the top part of the phone got pretty warm. The whole download process took about 1 minute and it was quite worrying that it got so hot that quickly just by dowloading an update for about 45 seconds..
I instantly put the phone back in the box and will return it today. I don't dare to buy this phone for so much money just to experience difficulties in the future due to heat problems.
Mine arrived today - still deciding whether to keep it or not
Was taking a few pics, nothing too strenuous and it got pretty hot.
I dont recall the Z3 having the same issue.
The Z3 have a different CPU, that's why it doesn't get as hot as the Z5.
I'm really worried and havn't totally decided about sending the phone back. I really like the phone but it just gets so damn hot quickly. Is this something to worry about in the long run? I guess i can get used to the phone being warm, but not if it can cause any issues in the long run. I mean, i don't want a broken or really slow phone in six months..
Got to admit, the Z5 does heat up a lot quicker than any device I've used in the past
Z- 5
Z3- 4
Z5- 6
The Z5 does heat up quite fast but it doesn't get "hot" it gets warm and its fine to touch. On my Z3 the battery temp i usually around 30 degrees celsius, whereas my Z5 would average around 35 ~40 degrees celsius. again it gets warm but not "hot." Whenever you push the CPU or GPU the back will get hot, so downloading a bunch of apps etc... will push up the heat and its normal for any device.

So the heat is nothing to worry about? No risk of reduced performance in the long runt etc?

Nothing to worry about, not unless you don't like the device to be constantly warm. It's much cooler here ok Vancouver right now so i can't say it would be around the same temperature for you.
I'm in Sweden, so it's pretty cold right now, around 5-10 C as highest during the day (40-50 F) so a warm phone is no problem, i would welcome it as a heat source when i'm outside
But i was just worried that the performance of the phone would be affected by the "heat issue", i really don't want to spend a lot of money on a phone where i might get issues with later on.
Bad things with overheat I have used Z5 for 5 days now. When the phone is charging it heats up badly and if you browse heavier web pages it starts to lag as does other apps and even launcher. If I run Antutu in these conditions it barely reaches 41000 score. I should mention than without charger pluged in (being colder or in other words regular conditions) it only reaches 50000 score, although, most reviews mentioned 60000 score. So this is my experience and I don't like it

BTW it heats up less because of GPU and more because of CPU usage. You can run 3D graphics for a long time and its not hot. But if you install anything or multitask (i.e. play music, run updates and browse) it heats up very quickly. And I repeat that I have only noticed it while being charged.

Guys, never do CPU intense tasks while charging, that's def going to heat up the device and consequently reducing performance!
As long as the apps don't close because of heat, it's all fine and the phone getting warm shows that the heat drain pipes design is working. The Z3+ closed apps due to heat = unusable. The phone getting a bit warm to the touch is absolutely nothing to worry about. Remember, there's an octa core processor with 3 GB of RAM in that slim device
Based on that input, do you guys see FCs of apps due to heat?
i can tell Z5 is far better than my Z4 (Z3+) in terms of heat. consider heat issue is nvr exists.
Ok, so I have done some more thorough testing with Antutu and temperatures. I have tested the Z5 in room conditions (22 celcius). The device was cold (from standby) and I ran Antutu. Score 50000.
Then I ran Antutu again and again and again. With every test the device heated up and the Antutu score... droped down. It dropped down to 42302 until the Antutu app was "unable to verify" the result (kind of crashed).
Then I put it in a freezer (in a sealed bag of course). The Antutu score was 66609.
A you can see the heating up can redue the Antutu score by as much as 35%.
I believe this answers somebody's question whether the Z5's heatup reduces performance...

You can't really say it's 35% because the high number is when you had it in the freezer. Any phone in the freezer is by definition not a normal use case. Your findings of a 15% decrease is within normal variation for a phone being used constantly, especially when using a benchmark app constantly.
While it shows it definitely heats up, it's not as big of a difference as you make it sound IMO.

Scientifically speaking this is a poor way to investigate the potential heat issue. Your primary concern is the temp and performance of the CPU/gpu, which does NOT consistently correlate directly with the temperature of the phone. In the case of the Z5, you have an actual heatsink combined with materials that are very good at transferring heat. The fact that the phone warms up quickly is actually a testament as to how well it dissipates heat from the CPU.
As for the antutu scores being worse, these scores are only useful so long as they represent real world performance. At the end of the day, you can still record 4k video for 30 minutes. I personally have not seen any slowdown related to heat. Downloading and installing programs does definitely heat up the phone, but the slowdown is because of the installation process and not the heat (in my experience) as this improves as soon as the install finishes.
I have done a lot of stuff with this phone and had no problems with performance, unlike my brothers g4 which can't navigate for long periods due to overheating. Yes the antutu scores show there is throttling, but I'm pretty sure every phone with this chip is designed to throttle to some extent. In my experience this throttling is irrelevant.
Every single core octa core phone throttles. This is my findings from 5 Antutu runs from identical cold starts (25C CPU temp) with all other apps closed on my three phones
Z5 : 62K - 54K (I won't agree with the 50K score he got on Z5 from the cold start, definitely lots of things were running in the background)
S6: 67K - 52K
Z3+: 57K - 46K
In terms of consistency, Z5 tops all of them. Considering the drama we've see earlier on other 810 based phones, this is a miracle Sony pulled on Z5. It could be the heat pipe or sw enhancements or both. No matter what - Z5 puts an end to that 810 drama.
Thank you guys for your answers so far! I took from your answers, the Z5 gets hotter than the original Z and some of you think that that's no problem and some think it's too hot ...
Ambivalence in regard to it's heat emission seems to be characteristic for this phone ... a lot of reviewers says it's ok while at least the same amount of reviewers says it's too much heat coming from the Z5 ... I'm still undecided ...
I've had the Z5 for a couple of days and even during the initial setup when it was updating and installing apps I was still able to use the phone normally and it didn't get too warm. I'm coming form the Z3 and I'd say they heat up pretty much the same - about 6-7 out of 10
Phone gets warm it's true, I remember my z1c going warm also pretty much the same 5-6 in the warm rank, but I tried a Xperia M4 last week and holy crap, that thing was super hot, I had to hold it from the bottom because the heat was unbearable, overall I am very happy with my new Z5, it's a great device
Got my one two days ago and must say gets pretty heated when I listen to music and play candy crush. Spoken to o2 and said that they would replace seeing as am in still my fourteen days cooling period. Am wondering that if I give it time will it change and settle?
Hi i bought the device two days ago and whenever i use it (i start opening Facebook, instagram, WhatsApp and other apps) it gets Pretty warm in the right side or the screen and behind. The CPU reaches 50 degrees and sometimes 55 and the worries me. What should i do? Is it normal or should i return it? I previously had an Honor 7 and it reaches the same temps but it doesnt feel that warm at the touch, it Just gets warm in the bottom left corner.
the temp while i'm typing is 41C, outside its 33degrees C and inside(where i am now) its 24degrees.
I do not believe this is normal whatsoever. My S8+ has been one of the coolest-running Samsung phones I have ever owned. You might want to return/exchange it if that is possible.
I have not used/tested with any apps to determine actual Temps but it never gets hot. It gets warmer but not very hot (like my S7 Edge did) when using Gear VR.
Have you done the simple things like closing all apps & rebooting? Clearing cache, etc? Maybe some app is "stuck."

I would say 5mins. Now it gets maximum 48 degrees in the CPU but i feel the screen and the body Pretty warm... Maybe it's me... I don't know. Feel free ti suggest me what should i do
it is absolutely not normal
my first device share the same issue with your's
well i ask for a exchange, the new unit just go to 45 when running games, most of time it wouldn't even reach 40 degrees
but
new device came with new problems, red tints, home button problem
it's up to you
ask for replacement until you'er satisfy with it
I would get an exchange(Yeah right the real me would hold on to it until it melted because i'm lazy). So far this is the coolest smart device I have ever owned. Even when playing intense 3d games and emulators it only warms up a little.
Thanks Guys! I'm going to return it on Monday.

If you're constantly scrolling and opening posts the phone will get warm, Facebook isn't exactly a battery friendly app, but if you're stuck at a post and reading it for a while it shouldn't get warm, it really depends how you use the phone. I can get my phone warm using twitter too. My friends z5 with the sd810 gets toasty.

Mate. The CPU throttles when it reaches 80C. What are you worrying about?
I advise reading your manual, which specifically tells you that the device will heat up with use and the heatpipe is located on the top right section of the phone x)
The reason why it may feel hotter than your previous (?) phone is because the metal rim (and whole body) acts as a heat spreader and the heatpipe connects to it with a thermal pad.

Trueee ?
Cpu temps keeps spiking up and down on any device that actually has a cpu.
What you need to look for is battery temp and not cpu temps. I consider battery temps a more steady measure of over heating rather than cpu as they dont spike.
Eitherways heavy bad background apps will make any device hot. Now if your just browsing on chrome with no background apps and your device temp ( battery temp ) is around 40c in a 20c room thats when ill be worried and exchange the device.
But hey thats just me
Gd luck !
