Insane CPU temperatures

Hey guys,
I am calibrating my battery atm and as you may know you have to discharge your device fully to calibrate the battery properly. To speed up the process I decided to install a stresstest app to my phone and guess what: the phone gets insanely hot, I can't even hold it in my hand longer then 5-10 seconds. Kernel tuner displays me temperatures between 78 and 82°C.
But this overheating problem not only happens with the stresstest. When I start watching videos on youtube or start using my phone for maps it gets hot too (about 60-70°C). It starts to bug me.
What do you guys think I should do to fix this? I already thought about applying some thermal compound between the CPU and the metal shield around it. But I'm not quite sure if it's a good idea. I already have a new phone but I still need two phones because I have to travel between Germany and Switzerland all the time. And this issue starts to make my Sensation unusable.

I would suggest an anker battery. It has a greater capacity and it keeps the battery very cool.

did you try different kernels?

Already using it and I'm talking about the CPU temperatures and not the battery's temperature.
And sure I did try different kernels. Even at stock kernel setting this thing gets hot as f***!

So I just decided to disassemble my Sensation and put some thermal compound on the processor chip. Now I'm not getting over 70°C at full load, 1,56GHz. Pretty good outcome. And under normal use it doesn't heat up over 45°C.
I really have to recommend you this method!

[Q] Heat Issues?

My HOX running on 4.2.2 Sense 5 stock rom is having heat issues i believe i dont know if its normal
PS default Kernel (still cant get Beastmode,god knows why)
i use "ondemand" as my governor and "noop" as my scheduler with set cpu
i also have trickster mod installed but i use it only for monitoring temp and on what frequency is the cpu running!
when its idle temp is temp of cpu is 35 degrees Celsius and battery 26 degrees Celsius
whenever I am using my phone for internet for benchmarks etc CPU is 40 degrees Celsius and battery is at around 32 degrees Celsius
the phone feels ok
but whenever i start any game no matter how simple it maybe (this applies for a wide spectrum of games ranging from * ball pool to demanding games like Asphalt 8) i notice my backside especially region around my camera getting warmer (now its not very hot but you can tell the difference)
at that time the reading shown is CPU is 45 degrees Celsius and battery becomes 36 degrees Celsius
PS the phone never restarts the game doesn't crash it runs smoothly
is it normal!?
i have read on web that lithium polymer batteries should be kept below 35 degrees Celsius for optimum life and performance
i dot have any background apps running whem i am gaming and the rise is observed in a few minutes or so i usually play a game for max 15 mins after that everything cools down!
this rise is also observed during taking back up through Twrp!

Those temps seem totally normal. Yes, higher temperatures are stressful to Li ion batteries, and hasten capacity loss. But to some extent, you need to try not to worry about it, and enjoy the phone for what it is.
While I don't game much, I do notice the phone getting warm while using Navigation, Netflix, etc. I've had my EVITA since just after release in May 2012, and I haven't noticed any loss in battery life.

you know the device very well and since u says its normal m glad
thanks u saved me i was thinking of what not like under volting and all those tweaks with the kernel!
Btw redpoint is i know the nature of ondemand governor but in my case it is either the max or min frequency it operates,so is it a good idea to switch over to powersave?
(and does our kernel support that)

Haven't used SetCPU in a while, but pretty sure if the option appears in SetCPU, its supported by the kernel. Depending on what kernel you have installed, more or less governor options will be visible.
Governor seems like a trial and error type of choice. It depends on how you use your phone, and not everyone will get the same results.

Lol those temps are nothing, I've had my battery up to 66° Celsius.

66° Celsius. seriously and that too the battery?
like is this normal?
besides the phone doesn't restart or get damaged?

Yep, 66° battery temp. That isn't a normal operating temperature though, that was while my phone was rendering a huge picsphere image from the Focal camera.
There are safeguards in place in case the phone does reach a temperature that would damage the phone. The phone will first warn you it's getting hot by flashing the led red and green, if it continues to heat up it will shut down.

What are your CPU and batt temperatures?

Just wanna ask around to check if I'm the only one who feels my phone is a tad bit too hot?
Usually when not charging , the batt temps are around 34-38°C, with the CPU in the range of 38-45°C
When charging the batt goes up to 38°C - 44.7°C or even overheating in the 45-50°C range( ok this would be my fault in using heavier apps)
And the CPU would stay in the range of 40°C - 55°C even without use sometimes

Those temperatures aren't out of the ordinary for this device, that's pretty normal actually. I've had my battery temperature go between 50-55°C fairly regularly, and even as high as 66°C without the phone shutting down (I did cool it down very quickly upon seeing how hot it was though).

Thanks timmaaa, for a moment I thought I was the only one.

I use Battery Mix to record my temperature vs. Battery % over time (use the JB feature to disable its persistent notification): https://play.google.com/store/apps/details?id=jp.smapho.battery_mix&hl=en
One thing I've noticed is that when it hits 40C+, the space below the camera becomes extraordinarily hot! This happens at least once during a work day, especially happens when I don't touch the device.
When this happens, the drain rate just plummets (when I refer to the battery level slope vs. the phone temperature). However, a reboot fixes the heat (and as a result, the drain rate) over a lengthy amount of time.
I've heard of this, but haven't gotten around to trying it successfully:

That shouldn't happen while you're not using the phone. Have you used an app like BetterBatteryStats to identify what's draining your battery?

well this was previously answered by timmaa i had a similar concern cause none of my earlier phone actually felt that warm...
but when i got a green signal that these are normal temperatures, i tried gaming for almost an hour turns out the phone was hot indeed the battery was around 50+ but still the phone dint shut down itself or showed any inconsistency in its functions!
moral of the story.. it happens with everyone.. my friend has a endeavor it also suffers from heating... its so normal that if u search it in google that "why does ht one x get..... "it automatically completes it in with " get hot"(also for the new One).
if you want to cool it down get SET CPU and create a profile in which select battery temperature/cpu temperature at a certain temperature you don't want your phone to exceed and then set the cpu to a lower speed typically till 1026 or 1134...
but again if u feel its necessary cause doing so will obliviously slow down the device.:angel:

Of course its normal. All computers generate heat as power is discharged. Manufacturers are also packing more and more computing power into these small devices, and in general that means more heat (although there are other variables). And every smartphone is designed to deal with the heat differently, so those might be some reasons why your previous phones did not feel as warm.

true that!!
even i was actually worried before hearing about it being normal from u and timma as well!
its probably htc one x is build that way.
BTW sorry a little off topic since this issue has already been resolved has anyone heard a little rattling sound near the camera region only when the phone is sharked up and down (from screen to back)
this also is a build issue!

Totally normal. Just a moving part in the camera module. Likely related to autofocus as you can sometimes hear a sound when focusing the image.

Overheating

My opo overheats without any heavy usage, I don't play any games.
I was on CM13, Darkobas rom and now Candysix rom but it still overheats what can I do?

Hi,
Have you tried a clean fastboot flash ?
Or can you upload some screenshots from an app like "CPU temperature" to see how is your overheating ?

Why you say that is over heating? Post some as about CPU and battery temp

This after ~15 mins of easy usage (battery temp. on status bar)

i don't this that these tempreture (48) is high...

So does anything happen when it starts to over heat?
Over heating to me would be 60s+ that's normally when the back of the phone is feeling very warm.
After I install a new rom, start up is rebuilding the cache and I've got it charging that's the only time I notice a hot back. Or if the GPS and 3g might be doing something strange.
If your phone is slowing down then look into it. If it seems fine but you just think the numbers are high then I wouldn't worry to much.
Where do you live? Is there a lot of direct hot sunlight?
Do you have loads of apps installed that might be misbehaving?
Or pick a rom that is slightly underclocked. Running it at max speed does make it warmer. Sultans kernel normally runs nice and cool. Think darkobas also uses it.

I used my opo for ~10 min I was on facebook and listening to music and my opo was around 38C that is not normal
I flashed CM12.1 with Sultans kennel but it don't seem to help, I live in Sweden it's around 25C but it overheats even when I'm home

That temperature is completely normal during use. If it was 80c then you can claim overheating, which it clearly isn't.

CPU Temperatures

Hi I was just wondering should I be worried, I was messing around with my phone tweaking it and installing a few mods and my CPU temperature went all the way up to 38 degrees Celsius, I'm not sure if this is normal or not? Please respond

if you install mod to boost performance or overclock cpu you should expect higher temperature.
however 38 c is not too high. have you tested temperature before those modifications?
specify mods you install to get better help :good:

I was only modding the UI with substratum etc, it seems to be getting quite hot though, I'll leave it for today and if it doesn't go down I might wipe my phone

How did you read-out the CPU temperatures?
Becaus 38c CPU is really low if you do heavy use your phone.
the temperature could possibly be the battery...
use this App to check the real temperatures... and don´t be afraid.. CPU rises upt to about 75C
