Stuck my phone in the freezer for a few minutes, took it out, and ran the stability test in AnTuTu which plots the temperature and a benchmark score. Looks like it starts right around 34 degrees (93 Fahrenheit), which really isn't that warm at all. You could get that just browsing around and holding it in your hand.
My cpu temp is normally in the 40's and 50's while browsing.
Have you tried turning the thermal daemon mitigation and high temperature property off in the hidden menu and see if this throttling happen? Will be interesting to know if the hidden menu selection works.

It does work. you can just open an app like setcpu and you'll see that it rarely peaks without disabling throttling. Just be careful as it does open you up to potential hardware failures and shorter life of the device. I only keep phones for around 6 months so I don't care but I'm not a normal usage case.

Wouldn't the hardware still have a thermal cut off point where it will just shut down the phone if it gets too hot? It's to my understanding that this hardware shut off point is different than the software thermal throttling. If anything, I think it will just make your device get too hot for comfort than do any real hardware damage to it.
I'm just throwing an educated guess out there though, I honestly have no real proof one way or the other.

Yes eventually it'll hit tjunction and shut down. This isn't even a safe shut down though. It is basically an emergency kill switch. It's like yanking the cord out of the wall on a desktop. Running at higher temps also shortens the life of the silicone. Much the same effect that overclocking has on a normal PC.

If it gets hot, it will do damage. It can fry the GPU before it even gets to shutdown point. The XBOX 360 for example had the RROD where the constant heat made the solder joints fail (I know the 360 is different but the heat point stands)

The 34 in this case is temp or battery, not SoC. The SoC is probably hit 75 Celcius and that's why CPU throttles. Try HWBot bench instead, it shows not battery but CPU temp. You will see that CPU immediately hits 75°

Afaik they shut down itself if battery hits 60°C or CPU burns to smthn like 105C
HWBot runs parallel... If you want to see your CPU get really hot press the button multiple times. Phone melted!
Why does the snapdragon get so hot. I don't understand what's the point of a fast chip in these phones if they can't run on there maximum lol.... Maybe that's why Intel is gonna take over qualcom one day.

It runs hotter because its having to produce all the pixels for the QHD. The same chip in other 1080 phones doesn't run as hot. At times doing normal things like browsing and Facebook etc my phone has throttled down to 1.4Ghz max and the CPU temp is up at 65-70deg C. That's pretty hot.

Its not the only phone. And mine never throttles that low doing normal tasks. It doesn't even throttle at all. However, when playing games or running demanding apps it does throttle.
Also, its not the only phone that runs this hot. All other phones will get hot and throttle just as much when running equally demanding stuff.
So the question was, what's the point of super fast chips when they are going to throttle themselves so fast?

I'd recommend that you do a bit of testing,run some apps for 5-10 min then open up a CPU frequency app. The frequency will be be at a low maximum and the temp high. The GPU also throttles, open an app like Faux clock after running some apps and the max GPU value has decreased. Without a doubt the extra pixels are causing this as the SOC is having to work harder to produce them. Its simple physics.B
But anyway, its a specs game. People want faster and better so that's why the SOCs get faster and faster even if they're throttling.

The soc is working harder, but like I just said the how soc is still hot even on other phones man.
Run the dead trigger on the s5 and the g3. They both most likely throttle down to the same limit while the fps on the G3 might be a little lower due to the resolution.
But like I just said, what's the point when the damn thing will burn. There is no point in 2.5ghz when your phone can't run at that frequency more than 5 seconds lol.
I remember when I used to run my Galaxy S One full speed. Not one but of throttling. These CPUs have not gotten any more efficient thermal wise.

Yeah, I agree there's not much point in having a super fast chip when it throttles so much. Again, people want bigger faster and better and most users wont even know about thermal throtlling.It does seem to be bad on the G3 though. I think I saw another thread that said LG don't use a proper thermal pad also. Don't know about that but to run a 1080 phone with the same chip as a 2k phone then you'll have thermal and performance issues on the 2k Vs the 1080.

The 801 is more than capable of driving a QHD phone. The 800 series are basically created to support up to 4k. And how will give the same performance as a 800 while on QHD. Its not even close to being a big deal. And yeah I saw that same thread. I wonder if it's true.

I see that the layered CPU/memory unit has a metal cover to it, im wondering if a thin thermal pad could be placed between them to conduct heat to the metal cover. Its not much of a heatsink, but it might help a little bit. It may even be possible to put a thin copper sheet on the metal cover to move heat away. It all depends how much room there is under the plastic cover. The only teardown ive seen doesnt make it very clear.

i was looking at the dissasembled xoom and for those who overclock there is a posibility that we can use the back cover as a huge heatsink by just putting in some heat tranfer materias on the cpu/gpu so it can make contact. Does it heat that much? i am wasting my time?

I am OC'd at 1.6 ghz and my Xoom has not gotten warm.
If it gets hot just turn down the cpu. I think that with the right ROM, running @1ghz is going to be fine. Adding insulation to the heatsink is only going to mask the problem.
ill check the temps with the cover off.. so far i can run @1.6 stable
the cpu is under a metal cover that is soldered to the board. and it doesnt touch the cpu because you can press on it and you feel when it touches it. lets see if i dont damage it when i remove it.. all pray with me
here are some pics of the us wifi xoom
I just watch 2 hours of tekzilla and hak 5. It never got hot and play great. I'm rooted 1.6ghz n loving it.
i have seen 37.8 C max at 1.6 interactive. I dont know if its too much or normal.
Must be ok. But the problem is i failed to find any kind of software to monitor the cpu heat.
I can only monitor the battery heat..

here is the picture.. yeah yeah it appeared that i bit it with my teeth .. didnt found my dremmel cutting disk so i had to improvise.. as you see i put in a thermal pad that's connect to the back cover and use it as a heat-sink
5 hours @ 1.7 and rocking hard!

I don't have overheating problems, but I can only run at 1.6. At 1.7 I get reboots, even with the new Tiamat 1.0 Rom.
I saw a pretty cool stick-on carbon fiber decal/cover protector, but I am afraid that If I cover the back, the Xoom will overheat.
What do you think??
i dont think it will overheat it because the cpu dont touch the back cover
Since ARM has on-demand frequency scaling, are you sure you are running at 1.7 all the time? Did you actually lock the freq at 1.7, or is that a ceiling?
i just locked both sliders to 1.7
btw is not battery friendly
why would you lock at 1.7?? Except when Benchmarking???'
I think that you will ruin your processor if you keep it up, even with better cooling. The processor is just not made to run at 1.7 full time.

Thanks, but that's not my concern. What I am worried about is that the case will act as an insulator and not allow heat to dissipate through the back cover.
i locked just to see if it wa stable.. and so far so good. and for the back cover there are no worries because it wont make any diference.. im the one using it as a heat sink
Did you run a CPU-intensive benchmark for the 5 hrs? That's the only way to tell if it's stable.
Good to see someone willing to get his hands dirty with a mod. I have to say, though, that the +0.1GHz added speed is probably not worth invalidating the device warranty. Not sure why you have to cut the alum shield as opposed to simply removing it. Then, you'd have the option of reversing the mod if you ever need to RMA.
Anyway, onto the next mod: how to boost your wifi range.
anyone notice that it get slower when the phone is hot?
i tested with quadrant standard when its hot i only get 2400 points and when it cool down a bit it get back up to 4600

That's pretty normal for all modern cpus/motherboards. Internal temperature sensors have the logic to slow down the cpu if it's overheating, in extreme cases, shutting it down completely to avoid physical damage. I think it's called thermal throttling.

All of my previous phones (evo, evo3d, evo lte, epic touch) and this one would get pretty hot under one of two conditions - playing 3d games or browsing certain websites. When I say hot I mean about 90-105F. If yours is getting much hotter I'd be looking into getting it replaced.
With normal tasks such as browser, phone and messaging, the CPU temp of my phone is around 38-40. With tasks as YouTube and graphics intense games it's between 50-55. At this point, the phone feels really hot.
Are these expected temp level or is there some problem with my phone?
With asphalt, the temp averaged around 65C. While downloading the additional content it reached 75C.
I rarely see mine above 45. I've only seen 50 a few times. Throttling kicks in bad above 50

How can i check the temp of the CPU? Most of the apps don't even show temperature on 6P and CPU Z gives me like 15 different readings ;/
For this I had used CPU Temp. But yeah after the update, it says that it cannot determine the temperature.
In CPU Z, I was unable to understand the readings. One of the app, said that there is no temperature sensor to determine the reading of the phone. So not sure if we can get the accurate temperature.
But the phone is for sure getting too hot. I feel Nexus 6p has heating issue, or atleast mine does.
45-60 shouldn't damage your CPU, but 75+ can be harming for phone's integrated circuit

Remember that it will go up to 70°C maybe higher and the aluminium case spreads the heat making the whole device hot (LG G3 was very hot only in specific area, because it was plastic).
Hey guys not to good at understanding this... I ran a throttle test because my phone keeps getting extremely slow... After the 10 min test it said my CPU was throttled to 48%... I am fully stock (Tho at one point i was rooted) and running Android 8 OREO on H910. I added a video of the throttle test. Could this be thermal related? I don't mind tearing the phone apart to replace thermal compound but if it wont do anything then why waste time right?

It was not plugged in. It did get hotter during the test which i thought was normal considering it is loading the CPU's.

Not sure but I have noticed that the CPU temp monitors are extremely inconsistent. I've had 4 tell me completely different temps than each other. If you wanna try a few mods before you try the thermal paste then I would suggest the thermal throttle mod which is only really supposed to help when charging but maybe it'll work for ya and try the MK2000 BTTF kernel if there is one for your model. Those have both helped my H918 and runs great even in hot climate it doesn't throttle.
Even so it's prolly a good idea to get the thermal paste ready for a change as my stock paste was pretty much completely solid. Cheap stuff whatever was used.
Just saw you were on Oreo. Most of the mods aren't available for Oreo yet or haven't been updated or tested so if your still on Oreo you might wanna hold off on the mods or at least make sure you backup the appropriate files before doing so. If you are still on Oreo that is
While playing some games I noticed my phone(N910H/Exynos) has a very hard time keeping framerates once it heats up, I downloaded 3D mark and a frequency/temp monitor app and discovered that during Physics test my phone throttles at 92°C and keeps frequency at 1500MHz(simply can't sustain the 1900 supposed max) to prevent burning, how can the CPU reach 90° while my hands are barely any hot?. Then I watched some disassembly videos and turns out theres no thermal pad/paste between the CPU and "heatsink"(these older phones don't really cared for cooling,it sinks heat to the frame).I re-did the benchmark while applying slight pressure over the CPU area and my physics score went from 1500 to 1600, still reaching 90°C but taking a little bit more time to do so, so it kept 1900MHz for longer.
So I though about doing the experiment of applying thermal paste over the CPU, but i'm scared I may brake the phone on the disassembly, so I'd like to ask if someone is willing to do the test to see if it's worth it. Maybe we can unlock gaming potential we didn't know was there, thank you guys.
[Update] So I did the test
TL;DR: There's already a thermal pad there, so it's not like the results are shocking, it does make a difference but it's not worth disassembling your phone just for it.
BUT there's an additional experiment I'm gonna make sooo things could change.
WARNING: if you're thinking of disassembling your phone for any reason be warned that the spen digitizer connector is a little bit hard to connect so it happens pretty often that it won't work, so test the spen before reassembling everything.
Long version:
Anan did not publish the OC kernel yet but I was too curious and did the thing anyway, you don't need to remove the screen from the mainframe so the procedure is not really that risky.
Turns out that pinky thing I saw on the images are thermal pads (as anyone not stupid as me would already know), not copper as I originally thought, anyway since thermal pads are worse than thermal paste(even the 2w/mk ****ty one I used) I did replace it, I had to use a generous amount to make contact, after all it's replacing a thermal pad(0,5mm i think).
Overall CPU temps got like 5-10°C lower, but the benchmark results are pretty boring since they don't thermal throttle the CPU much, geekbench got 100-200 average more on multi core (no difference on single core) and antutu went from 99251 to 103408 ,CPU multi-score went from 26136 to 27971. The stress test basically achieves the same temps, only taking a few seconds more to throttle.
However,gaming performance did get a considerable boost,since they offer a constant heat output. Minecraft( yes it thermal throttles the cpu a lot) almost doesn't see throttles anymore granting a SIGNIFCANT better performance, Free fire also does perform better but stupid me did not pay attention to temps before the mod.
Heat on the phone also feels WAY less concentrated on the CPU area.
Now if you know a little bit about this stuff you know that thermal pads are usually used when the heat source is not touching the heatsink, which is the case here. I am 100% sure the results would not be this boring if the CPU actually touched the midframe, so I'm going to do another test sometime putting a 0,5 mm copper pad(401 W/mK vs the 2 from my thermal paste) to see the actual result I was expecting.
I know all this sound pretty stupid and pointless but I'm going to use this phone for another year or two so I want to make the most of it, also I really like this stuff.
If you want to know WTF is even going on you can watch this video/read the article: https://www.gamersnexus.net/guides/2137-thermalpaste-types-conductivity-and-more
I think someone has already done that, don't recall the thread

A custom kernel would not solve this problem, as you need to get heat away from the cpu so it can maintain high power usage and low temps.
The only way a custom kernel would help the cpu run cooler is trough undervolting or increasing temperature limit, the latter is obviously dumb, about undervolting I have already tried managing mere -50mV wich did not change a thing.
So Anan confirmed he's porting Helios Kernel V3 to the lineage 15.1 rom (wich is the one I'm using) then well be able to overclock to 1500/2100. Once he posts that I'll see just how hard this phone throttles and then maybe do the procedure myself.
I got :
99251 on Antutu
1114 single 3734 multi core on geekbench
It throttles in both
the stress test in Antutu gets it so hot Im not really confortable letting it finish, it imediately reaches 90°C, keeps oscilating between 900 and 1900 on the big cores,in 5 minutes the entire phone is burning hot.
