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.

I know many people have been saying the low benchmark scores on the Nexus 4 are due to "thermal throttling" but I don't really believe this. It's supposedly based on the optimus g, and if that doesn't suffer from this thermal throttling issue, then why would the Nexus 4? I personally believe it's just due to the software. People are also saying that an update won't boost the performance by that much, but I'm not sure what to believe.
So do you guys really believe that the nexus 4 is over-heating and under-clocking itself, or do you believe it is just in need of an update?
It may be a faulty unit from that reviewer, I only recall one review saying it overheated. The software is also to blame. I made a post in another thread about the performance with these pre-release software versions the reviewers have.
http://forum.xda-developers.com/showthread.php?p=33634026#post33634026
Unfinalized software on all these review devices is probably the bottleneck. Not to mention benchmarks have zero bearing on anything ever.
And Testing units and software do have a tendency to carry heavy logcats and monitoring software... I remember from the ICS days how "heavy" most leaks would run progressively getting better by the update ...

Whilst benchmarks shouldn't matter too much, when this beastly specced phone is getting worse scores than the msm8960 with adreno 225, then it will obviously raise some concerns.

I wouldn't say I'm good or experienced enough with Android smartphones to decide whether or not it's due to software, but I sure hope it is. I'm really only judging this particular issue by what everyone else is saying.
In regards to the sceen size and "Nexus 4" theory, I agree. Nexus 7 and Nexus 10 are a good example of device names in correlation with screen sizes here.
just wondering why did google name their nexus phone 10 wbefore the fourth one
I think it all came from a comment at Anandtech, they attempted to run all the GLBenchmark tests one after another, most web sites just chose 1 or 2 tests, usually Egypt HD. Most devices crash when trying to run all GLBenchmark test serially, it does on my Nexus 7, something to to do with running out of memory allocation.
Nexus 4 in a kind of suicidally awesome way completes the entire GLBenchmark suite in one go, but running all those test including offscreen & onscreen is a long brutal test, maxing out the SoC in a way no game is likely to do, so the fact that the device is thermal regulating itself is not that strange.
If Anandtech tested individual elements of GLBenchmark, as most other review sites do, this issue would not have occurred. In fact they admitted that the Optimus G could not run all tests consecutively, so they only tested individual elements, hence no the device didn't get downclcoked due to thermal limits. It is not good that Anandtech has this disparity in testing methodology, I like the website a lot, but some thing recently have led me to question a few things, but that is another story.
Every phone overheats nowadays so there's nothing different with the n4.
This is pretty interesting
Benchmark comparison. Once at room temp, once in freezer. Freezer scores are significantly better

So yeah... Kinda does look like pretty bad thermal issues Hopefully just cause it was pre-release or something

But they singled out the Optimus G, because it was unable to complete more complex tests because of crashes.

Wow, that is a very interesting find. I was actually thinking that someone should do a freezer test just see if it is overheating. This article would seem to prove that it is. Those retests show dramatically higher scores, more on par with what the S4 processor should be capable of.
They said that perhaps the retail versions will have a higher tolerance for heat because they did not think they felt that hot. More testing and info is needed though.

To elaborate, straight from the source, in the Anandtech podcast this morning Brian commented that the phone seemed to be set to throttle at 60 degrees (for the dual-krait S4 at least it's usually around 80 afaik) and at that point the exterior of the phone was much cooler than a lot of other phones. (He talks about it at about 00:51:00.)

That means it's a simple tweak, and so as long as people aren't noticing excessive heat (which we would have heard from reviews) on the phone itself then is sounds like things will be fine for the release.
Yes IT FREAKING OVERHEATS

I've had the phone for five days now and it definitely overheats. The last time it overheated was this morning. I got up, looked at the phone and unplugged it from the charger. Went to attend to my toddler for 20 mins and came back and saw that the phone was very warm and battery life was hit 20 percent. I did a check on battery usage under 'battery' in settings and saw that the playstore app had sucked 50% of the power of late. This is HIGHLY unusual becuase usually the screen is what sucks the most juice. I turned it off and turned it back on and it went back to being normal. During this overheating the phone stutters EXTREMELY visibly. Probably due to the massive thermal throttling of the cores. Once it cools off it goes back to being normal. This happens randomly and occurs once or twice a day. I've reported the bug to google. Otherwise the phone is superb.
That sounds like the Play Store app is misbehaving. Have you tried clearing the data?

Remember it's winter at northern hemisphere. So overheating might not be obvious.

Same thing happened to me earlier today, I unplugged the phone from the charger and was extremely hot. I panic and shut the phone off. I rooted the phone last night so that was the only thing I did differently. I've had the phone for almost a week.
I also noticed the battery was draining way too quickly.
More like rogue apps... had the phone for over a month now, heavy usage every day and never once has it "overheated"as people say.
If im multitasking, like listening to music, downloading a torrent in the backgroud while playing angry birds or something the top back of the phone will get warm, but nothing unbearable if i deliberatly grab and hold the phone at that spot.
It's a glass phone... it will get warmer than most people are used to... its bascially the same glass that the new kitchen ovens use as a top surface... if you can cook on a glasstop stove... a phone heating up will be the same principle, albit on a smaller scale..
So yes, for the people complaining about heat.. then say in the next breath that they lost battery in some % form... funny how nobody is telling what they have installed as extra..or post screenshots of the battery page to back up the claim with info so we can help...large loss of battery % right away points to a rogue app somewhere.. you dont magically lose 10-20-50% whatever battery when unplugging the phone... thats something stuck running that is forcing your cpu to run at max for an extended period of time.
so as the internet expression says "fraps or it didnt happen" (screenshot or it didnt happen) lol
I am seeing battery temp reach 40C during antutu benchmark test running 4.2.2. Looks like it is only affecting a few devices. It gets warm during the benchmark test but nothing like unbearable heat.
Dear Community,
In this thread I want to gather a sample to investigate to what extent the S4 suffers form overheating and how this affects the battery drainage/life. I urge you to participate as I am collecting a sample to submit a formal complaint to Samsung to raise awareness to an issue that is widespread among S4 users and to push Samsung to address this issue accordingly. In order to provide your sample please follow the instructions below and report back in this thread with the relevant information. Please first indicate which variant you have: Quad/Octa (i9505 or i9500)
Please download BatteryGraph (it's a great app to measure Battery drainage accurately) https://play.google.com/store/apps/details?id=com.modroid.battery
Run it once after download to initiate logging. Let it run for 10 minutes to allow the graph to built up a bit.
Then please Download Antutu benchmark run the benchmark fully exactly 5 times back to back (continuously). After that please enter the stock dialer (as quickly as possible) and enter *#0228# and post the temperature (external thermistor) after the tests in order to determine the maximum temp that the device reaches under continuous stress.
After that, please enter the app Battery Graph and zoom into the graph to the maximum level. Scroll slowly along the curve at the time when you performed the Benchmarks and tell me if there are interruptions or 'skips' where the battery drops 1 or 2 percent at a time and where the App does not Register a graph for those drops. Sequence/scroll slowly along the graph 1% at a time and make sure that the battery dropped 1% at a time. Please report of the battery has dropped more than 1% at a time. Please make a screenshot of your battery graph in the App and post it here for collection. I will analyze the graphs subsequently and compile it in SPSS to submit our findings.
If there is a drop of 2 or 3% at a time it means that you are experiencing Battery Percentage skips/cliffs which could indicate either a defective battery or defective device which might be the cause for the extensive heat development.
Thank you for your participation. Hopefully Samsung will listen to us and address the issue to give us the perfect S4 that we deserve.
Best,
Thomas from Germany

That battery app polls for battery level changes every 5 minutes by default. I think almost every device will experience a drop of more than 1% every 5 minutes under constant stress testing. You can change it to poll every 1 minute in the settings, which you might want to mention, but even so isn't it entirely possible to lose more than 1% a minute with everything turned on (GPS, Gestures, etc.) and ~17 minutes of constant cpu/gpu stress testing? It's a nice idea but it doesn't sound like it would yield very accurate results, unless I've misunderstood your post.
EDIT: Nevermind, I see how you can step through it 1% at a time now.

I've also noticed that you cannot really zoom in very far and at the highest zoom setting the % is still displayed in multiples of 10. Kind of tricky to differentiate between a 1% and a 2% drop.

You might be right, what would you suggest in order to yield more accurate results? I suspect that the heat is directly linked to a very quick drainage of the battery. How can we measure how much it affects the actual battery drainage?

I'm not criticizing you or anything and I'm not saying it's a bad idea, It's just that obtaining accurate battery results are tricky as everyone's device is different, has different settings enabled and are running different kernels/ROMs/etc. Batteries also seem to get more efficient as time goes on so newer devices might suffer from higher battery drains.
I'll run the battery temp test now though and see how hot mine gets!
I like your critical thinking, obviously you are right it is very trick but I believe the heat test itself could be very indicative. In the meantime I will try to find a better way to measure battery drainage.
So everyone please try to run the benchmark multiple times and submit the temperature.
The most I was able to get was 52C
Thanks
Pre-test: 29.9°C
After 3 tests: 35.0°C
After 5 tests: 37.7°C
After 7 tests: 38.4°C
After 10 tests: 38.8°C
The temperature increased less and less so I don't know how much higher I could get it.
Also, an easier way to poll the temperature is to do "adb shell dumpsys battery" over ADB. The temp will be displayed as something like 388 which means 38.8°C
Edit: It might be worth noting that the top of the phone, around the camera but more so on the screen side (so the cpu?) got incredibly hot. Almost too hot to touch. Kinda worrying, but I have spent the last half an hour stress testing, I guess

Thanks for your contribution Meltus! Really appreciated my friend. Also thanks for the ADB command it does make it easier but I doubt that you've read the correct temp as 38 appears to be quite low compared to what i got. Is your S4 a i9505 ?

It's also the temperature that dialling *#0228# gave me (I double checked they were both the same each time). And no, I have an i9500, running Omega ROM, if that helps.
Might want to mention the elementary precaution of taking off all case covers except for the stock case before testing to prevent insulation effect of case covers increasing battery temperature...
While you're at it you might want to standardize room temperature to 25 degrees C... I know for a fact that my device would never get hot no matter what it does if running in the freezing cold air-con'd metro...
What about brightness settings and whatnot. Should all be the same, so you have to give a standard.
Pre-test: 36.2°C

After 5 tests: 54.6°C

dafaq right??? im really annoyed at sammy for this overheating S4... after 7 times testing the Antutu, i stopped and LITERALLY put my S4 in the lower compartment of the refrigerator to get it cooled down quickly cause im pretty sure the heat sensors inside would definitely be having some testing errors and the temperatures would be really really higher than that. even when i swipe between different homescreens the phone gets to 47°C which is really annoying.
can someone pls for the LOVE OF GOD provide any solution to this freaking problem? i have been worrying a lot for spending my $730 on an overheating phone...

Are you talking about the battery temperature? If so something is extremely wrong with your unit, my battery temperature never went past 45 even with high stress.
If in case you are pointing out the cpu temperature then there is no reason to freak out because the cpu can handle upto 90c + and can cool off pretty fast
Edit:
And why on earth you ran Antutu for 7 times continously lol? None of the current generation phones can handle it for 7 times on a row afaik

im talking about the cpu temps. i ran antutu cause it was asked to be done for this thread.
and why would it be silly to run any app 7 times on the flagship device? its made to run the apps as much as people want thats why we pay a huge amount of money for these devices dont we? or else we should buy the low end devices
just saying cause i had heating up issues with devices before infact my last device Note 2 used to get a lot hot but not as much as this S4...
i desperately need a solution for this...

You are not buying a flagship device just to run Antutu n number of times, do you? yes I accept we do pay huge money but that doesn't mean we can push the limit of a mobile and complain about it from a general user perspective . , it can be only done for experimental purposes and to understand the power /thermal envelope provided that it's done in the right way.
But how does running Antutu 7 times matches a real life scenario? Highly unlikely isn't it?
We are already pushing the limits of raw cpu power for a mobile, raw a15 cores are power hungry and often tend to heat faster than previous generation. Hence arm introduced the big little. The mobile heats up during heavy stress, but but that's expected with these powerful cores right? I'd better utilize the power wisely when needed rather than using it all the time. The cpu indeed gets hotter when stressed, it's the same With my s3 too the cpu temps reached upto 80,there is built in throttling mechanisms which will take of the cpu once the cut off temperature is reached. Have seen many benchmarkers these days using freezer test due to the thermal throttling in new gen devices. Yes the s4 heats up pretty quick than other mobiles but also cools down pretty fast and I think that's the way it is destined to work.
Hei one more thing, did you note how long it took to fallback to normal temps?

Are you talking about the battery temperature? If so something is extremely wrong with your unit, my battery temperature never went past 45 even with high stress.
If in case you are pointing out the cpu temperature then there is no reason to freak out because the cpu can handle upto 90c + and can cool off pretty fast
Edit:
And why on earth you ran Antutu for 7 times continously lol? None of the current generation phones can handle it for 7 times on a row afaik

We were doing it to see if there was a correlation between excessive battery drain and overheating batteries. Mine never got any hotter than 40 and I have pretty great battery life. The OP was seeing temps of 50+ and I'm guessing he has poor battery life.
Could there have been a few batches of bad batteries sent out with devices?

Dear Community,
In this thread I want to gather a sample to investigate to what extent the S4 suffers form overheating and how this affects the battery drainage/life. I urge you to participate as I am collecting a sample to submit a formal complaint to Samsung to raise awareness to an issue that is widespread among S4 users and to push Samsung to address this issue accordingly. In order to provide your sample please follow the instructions below and report back in this thread with the relevant information. Please first indicate which variant you have: Quad/Octa (i9505 or i9500)
Please download BatteryGraph (it's a great app to measure Battery drainage accurately) https://play.google.com/store/apps/details?id=com.modroid.battery
Run it once after download to initiate logging. Let it run for 10 minutes to allow the graph to built up a bit.
Then please Download Antutu benchmark run the benchmark fully exactly 5 times back to back (continuously). After that please enter the stock dialer (as quickly as possible) and enter *#0228# and post the temperature (external thermistor) after the tests in order to determine the maximum temp that the device reaches under continuous stress.
After that, please enter the app Battery Graph and zoom into the graph to the maximum level. Scroll slowly along the curve at the time when you performed the Benchmarks and tell me if there are interruptions or 'skips' where the battery drops 1 or 2 percent at a time and where the App does not Register a graph for those drops. Sequence/scroll slowly along the graph 1% at a time and make sure that the battery dropped 1% at a time. Please report of the battery has dropped more than 1% at a time. Please make a screenshot of your battery graph in the App and post it here for collection. I will analyze the graphs subsequently and compile it in SPSS to submit our findings.
If there is a drop of 2 or 3% at a time it means that you are experiencing Battery Percentage skips/cliffs which could indicate either a defective battery or defective device which might be the cause for the extensive heat development.
Thank you for your participation. Hopefully Samsung will listen to us and address the issue to give us the perfect S4 that we deserve.
Best,
Thomas from Germany[/QUOTE]

Battery temperature. If someone's experiencing temperatures in excess of 50C and bad battery drain it would indicate a problem.
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)

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

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.
Hi has anyone else looked at the thermal throttling on this device?
I complained with the initial release.
I haven't seen anything.
My LG G6 with a Snapdragon 821 outperforms this phone.

Run Antutu back to back and watch your performance degrade.
Run Geekbench or Vellamo and post your scores.
The SD821 device is an LG G6 and it uses a heat pipe to get heat away from the CPU and it scores the same kind of numbers as the Essential unless you mess with thermal-engine.conf on the Essential.
I've tweaked mine and phone is blazing fast now and doesn't throttle as early.
Stock this phone throttles like crazy.
Is this phone just slow, like almost unusably slow all the time? Over here, I got it less than a week ago, stock, maybe 30 apps in total, no major drainer such as FB or the like.
And yet, compared to my one year old OnePlus 3 this is crawling and painfully slow. Just earlier today I erased its cache and restarted it. It helped for a few minutes I guess. When it's slow like this, can't listen to Google music via Bluetooth because it's stuttering continuously, every once in a while I'd touch an icon and it takes seconds to start an app and no feedback from UI until then. A few moments ago I was taking some photos with stock camera and attempted to delete a pic from thumbnails, the app froze for a few seconds then it just deleted 2 pics in the meantime.
I bought this during the bf deals for 400$ with camera but thinking of returning it.
I only wonder how anybody else finds this phone usable at all in day to day usage?

It may, but the the thresholds for heat throttling are so low you can force throttling just by running Antutu.
Until I played with the "thermal-engine.conf" getting reliable results was hit or miss.

For ****s and giggles I just ran Antutu three times in a row. I stared at it so I could take the screenshot of the result immediately after it's done and run it again. The phone is just sitting on my desk, it got warm but not as hot as my HTC 10 did and nowhere near where my Nexus 6P burned at. Looks like a little throttling but not very much.
And then I ran Geekbench 4 right after the third run because I already had it installed and got 1898/6470. Normally get around 1850/6500 so the result I got after so much heat build up doesn't seem like any throttling there either.
Stock Nougat NMJ51B, Magisk rooted so I can use Titanium Backup and Adaway.
I dunno, maybe you have faulty hardware?

Ran Antutu 3x and got the following:

In that order. I dont see any throttling occuring. Running on the Oreo beta, no root.

Interesting app. So it does appear to throttle, but honestly, any passively cooled CPU running at max speed for a consistent period of time would have to eventually. The type of stress an app like this puts the CPU under is uncommon however, even intensive games will not consistently stress the CPU as much as an app like this.
That said, my throttling doesn't appear anywhere near as dramatic as yours, and it recovers quickly, as soon as the temp drops below a threshold it spikes back to near full performance.
This is how Intel and AMD's turbo boosts work as well, they will boost to a certain speed until it is thermally not feasible for the safety of the processor.
Qualcomm's own documents state that the performance cluster of cores supplies "up to" 2.35GHz
https://wccftech.com/qualcomm-snapdragon-835-specifications-design-details/
Throttling under extreme conditions is normal. Even iPhones throttle after a bit if you put the right kind of load on it.
The question here is whether it throttles more than the LG G6 and I can guarantee if the OP tried running that particular throttle app on the LG G6 that it'll throttle too.

I haven't run any throttling app.
I have just found that running Antutu two consecutive times yield wildly different results.
I also found that even slightly above room temp, the phone will throttle.
This was the case with the very first one I had at release and the one I got through Sprint on Friday.
And the throttling is much worse than my LG.
In the same tests my LG will throttle much. much later then the Essential.
To the point that I can get better performance with my LG than I can with an unmodified Essential.
I meant this app posted by avd: https://play.google.com/store/apps/details?id=skynet.cputhrottlingtest
Try running that on your LG G6 and take a screenshot.
Anyway, if your Essential is throttling that much, it's probably defective hardware, maybe the heatpipe isn't seated correctly.

This was a 5 Minute test of GIPS with the application.
Peak Ave Min %Throttle
LG G6 -> 99.4. 81.9. 38 63% (Took more than 2 minutes before it dropped to below 90% in performance. )
PH-1 ->137.86. 103 69 69% (Throttling in the first minute and cycled but rarely got above 75% perf).
PH-1 ->137 116 94.95. 81%. (This is with a custom thermal-engine.conf you see dips but not many below 90%)
So the PH-1 throttles early and hard, but it levels out.
The LG manages heat better but when it throttles after 2-3 minutes it's pretty hard (50%)
How this translates into real world performance is that the stock PH-1 will appear to lag, since under load it throttles early under short peaks.
The LG takes longer to get into a state of throttling so it feels smoother.
So in short benchmarks; Geekbench Vellamo and Antutu where you get some shorts bursts of high activity the PH-1 will ive unreliable results because of early throttling. The LG G6 will look better because it takes a lot longer to throttle. Benchmarks will be more predictable and performance will appear better. It looks like the LG G6 heat pipe is more efficient, but when you saturate it, game over.
Since the Essential throttles early the limits to 67% of the clock while throttled it has overall better characteristics when throttled.
The LG on the other hand, takes a while to throttle but the first step down in performance is to ~50% clock frequency.
Anyway, with a custom thermal-engine.conf things are much better.
A custom kernel would give better results.
Don't get me wrong, I like the PH-1 but it throttles early.
This is my second device with a three month separation in build date.
The odds of me getting to with a wonky heat pipe are pretty low.
Where's your screenshot? We have two examples here where the PH-1 with 8 cores throttle to 65% and 80% but in a All-Core test like this, the SD821 is only 65% the speed of the SD835 in the first place.
Even throttled to the screenshotted levels, the Essential can still keep up with the LG G6 at full speed

Hi,
I don't have the ability to do the screen shots.
But as I indicated, it takes a lot longer for the LG G6 to start throttling.
It takes almost 2 minutes before any throttling on the LG G6 (+90% of max performance), but the PH-1 will start almost immediately.
So the LG G6 is at +90% but the PH-1 with the stock thermal-engine.conf almost immediately throttles to 60-70% then recovers and stabilizes some time later.
So as I said the overall performance of the PH-1 s most definitely better, but the PH-! may appear to stutter under heavy load initially, where the LG G6 takes longer to throttle and will appear to have more stable benchmark performance for short benchmarks.

Here is the thermal file I use.
You have to be rooted and it goes into /system/system/etc with 644 permissions.
Also you need to remove the ".txt" extension.
It looks like in the last few update Essential has tweaked performance.
I don't see any throttling like before.
So, I purchased a replacement battery for my V20 from Amazon. I wen't with the Perfine 3,200mAh as I couldn't trust that the "original OEM" batteries were genuinely original. However, I've noticed (as one other review on amazon mentioned) that the temperature sensor in the battery isn't working. It constantly seems to read around 22°C no matter what. The other day my V20 became very hot during use, possibly dangerously hot (I don't think this was related to the battery, it was a fairly hot day). I checked the temps using Aida64. One of the temperature sensors, "tsens_tz_sensor11" read 71.4°C!! I immediately shut the handset down to be on the safe side. I don't think I've ever had a phone get this hot. Is that normal? Or even safe? And how dangerous is a battery without a temp sensor? - I'm guessing not very safe at all

Sorry, I didn't really make that clear enough. There are a ton of fake "Genuine LG OEM" branded batteries out there. They're all skinned like the official battery that came with the V20, with a few minor differences. This make it really hard to know whether you're actually buying a genuine LG product or not.
The battery I bought isn't a knock off, it's a third party battery. The capacity of this replacement is great, actually slightly better than the genuine one that came with my V20. The only issue is the dud temperature sensor.

71C is high, is that after running a benchmark or something?My note 4 used to go over 73c sometimes .My cpu idles around 28-30c ( i changed the thermal paste) and goes to around 60c under max load.I'd recommend changing the thermal paste for sure. Regarding the battery, it's probably the temp sensor on the Battery IC that's not compatible with V20?

I was on 4G at the time, and only checking Reddit and reading the news. Nothing intensive at all, which is why I freaked out a little. Room temp was probably around 30°C at the time.
I reckon you're right about the temperature sensor. It does seem to get some sort of reading but always hovers around the 22/23°C mark. Should I be worried about that? The battery obviously has a temp sensor for a reason. I really don't want a note 7-esq experience any time soon...

yeah you never know.When charging batteries( especially non-oem) best to have fully functioning one especially from a safety standard.Yes, there are good reasons for battery temperature sensor.It says a lot about the health of the battery , like if its prone to failure in the near future.This is a wild scenario but say if your battery starts expanding rapidly it's gonna be very hot and phone will be made aware(99% chance this isn't gonna happen but just an example).You may have noticed if you use Fast charge, the battery gets hot, nothing crazy but hot nonetheless.So if your device is fast charging, it may send false battery temp readings and fast charge may keep sending higher voltage or current(i think fast charge is like 9v) because as far as it knows battery is not at temp threshold. Obviously voltage threshold comes in to play primarily, but you get the the idea.That's just another scenario i could think of as an example.Have you tried checking temps with other apps like cpu-z for consistency? Yeah i see why your temp is so high 30C room temp, that's so hot lol Mine is probably 14C .
My battery definitely goes above 23c so yeah something is wrong there.
Interestingly i once made my phone reach 90c with lineage os running kernel auditor and cpu on max speed. I could not touch the fingerprint se sor. Im not sure if it was really 90 or kernel auditor was wrong. Battery and everything was stock.

Thanks a lot for the feedback, I reluctantly returned it today. It's a shame because it really was a huge improvement over the stock V20 battery. I've taken a punt on another third-party replacement. Fingers crossed!

Interestingly i once made my phone reach 90c with lineage os running kernel auditor and cpu on max speed. I could not touch the fingerprint se sor. Im not sure if it was really 90 or kernel auditor was wrong. Battery and everything was stock.

Holy moly! That's ridiculous! haha. I know CPUs can withstand very high temps, but 90°C in a smartphone is pretty nuts!
