Insane CPU temperatures - HTC Sensation

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***!
Send from my hovering Note 2

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!

My Sensation XE gets a tiny bit hot?!?

Ok, ill just tell you where I'm up to here... I bought the XE, about a week ago after upgrading from my DHD. And ever since I started the phone up, I realised compared to DHD it is mega hot.. now before you point out, I do know XE has dual core .. I play games, browse websites, facebook etc.. and I find the phone getting extremely hot to the point I've been monitoring it all the time..
Browsing websites, I've seen temps of around 57 Celsius
Playing games, I've seen temps at 69 Celsius
Normal idle is usually hovers between 30-45 Celsius
I don't know if these are normal for a phone, but in a cold room my mobile acts as a radiator.. sometimes its that hot I feel I shouldn't be touching it..
I had my first one last week and I got the exact same result.. rooted and stock.. Sebastian kernal and stock.. ICS/GB.. and everytime the result is the same.. so I took the phone back to carphone and they replaced it with a new one..
This is what is confusing me about whether this is normal, because the outcome is exactly the same... I've underclocked, it did nothing.. it is also nothing to do with my battery as it usually sits at a comfortable 25-37 Celcius and only rises due to my CPU heating my entire phone and also my entire home..
Could someone please help me with a little info on whether this is normal.. or whether I'm entitled to a complete different handset as carphone as the overall experience with this overheating is making me a little edgy as to keeping the phone incase it explodes..
Right now my CPU temp is 59 Celcius, and that's just typing this message "/..
It happens on both XE's and I'm using system tuner to record CPU temp
Thanks guys
69 celcius? Mother of Heat (yea... A meme)
My Sensation also gets hot, but not that much. Maybe 43 Celsius the max temp It has reached. The problem its because of HTC's cheap battery mainly. Though you shouldn't expect your phone to be cool when it's having a load of charge (process) to deal with

you can definitely expect your sensation to get hot every now an then. especially while charging and doing anything mildly intensive. usually while playing games like dungeon defenders my phone gets super hot even through the TPU case. it's nothing out of the ordinary though so don't worry. it won't explode in your pants
This is the HOTTEST phone in the market

To check your CPU temp just use system tuner from the market.. and for your battery temp, just search for a battery monitoring app I forgot which one I used as when I found it wasn't my battery I uninstalled
My sensation also gets hot all the time on heavy use.

Open phone dialer and type *#*#4636#*#*
You can remember the "4636" part by seeing that it stands for "info"
This will only show the battery temp tho, but you don't need any 3rd party software
i been gettin same readings on my sensation xe im scared to play games for to long in case it causes a problem with the cpu / gpu... usualy playing games like real racer 2 i get temps up to 70c, i use system tuner to monitor temps..
Look like I had worse temp compare to everyone here.and I wasn't even playing a game.because sensation was too hot to touch.
Here are some pictures and what you said about underclocked is true. It doesn't make any difference and the phone still get very hot.
A new battery may bring your temps down...
Sent from my HTC Sensation XE with Beats Audio using XDA
i have the same problem, but not that bad. it maybe goes up to 50-60 degrees.
i tested many different roms and kernels.
i have to confirm: underclocking does nothing it still gets hot. i cant say if its the battery from htc, but i can test that soon. i order an anker from amzon. have heard that one is better in other posts here.
i also noticed one thing today. it gets terrible hot while charging and doing stuff. so i tried to charg it from my pc and it does not get that hot anymore. maybe its the charger itself, but i can not confirm that, because it gets hot when not charging to.
what i also saw is that its not that bad anymore after i got a new rom an new kernel. im on vipers and bricked kernel with default settings. no setcpu or system tuner installed.
maybe that hepls

[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:
http://forums.androidcentral.com/ht...g-red-while-charging-rapid-battery-drain.html
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.

[Q] Serious Nexus 5 overheating problem

Hello. I'm new with the account here, but been reading this forum for years.
I'm creating this thread because my new Nexus 5 (which I have for 20 days now) is overheating more than a normal mobile device should.
When i bought it, it had 4.4.4 Kit kat android, and I had that one for about 5 days, and in that time, I didn't notice any overheating, or maybe didn't pay attention, can't remember really.
But after installing official Lollipop 5.0.1, the device is heating pretty good even when browsing internet for 5 minutes, at about 30-40% brightness.
**** Please tell me if some of your devices are acting the same, and is it worth a try to install back an older android to try if it will stop overheating, or my device may be faulty and should I take it back for another one (or maybe switch to LG G2) ?
Because I'm still unable to post image links, i will write it down:
- Ambient temperature: 23 degrees Celsius
- The temperature sensor is taped on the back side, at the side of camera, this is where it overheats most. (even if not using camera)
- Phone temp after staying on standby with screen off: 28 C (it's not warm but it is warmer than desk which it is sitting on)
- After staying idle on home screen with screen on for 10 minutes (50% brightness): 30.5 C
- After chatting on Messenger for 10 minutes: 34.3 C (feels warm)
- After recording video for 4 minutes: 41 Celsius!!! (almost uncomfortably hot in the whole upper half of the phone, both the back side and the screen)
- After 15 minutes letting it cool down, with screen off of course, it is 38 C (still hot to touch), and it stays like that untill I reboot the phone, then it cools down.
The test took about 50 minutes, and after that, battery was drained for about 25%.
-While charging, the phone does not overheat, just gets a little warm which is OK. (haven't tried wireless charging)
P.S. I don't play games on the phone...
Please act quick in case I should return the phone...
the only time my phone gets hot is when im intensively doing a lot of things..
for example.. im playing ingress, have tether ON, and my two sons are using their tablets connected to my phone playing ingress too..
but if i turn off the game and turn off tether, it cools down..
to me it sounds u have something intesively using your CPU and perhaps GPS and other radios.
hold power button.. when PWR OFF shows, long press it and reboot into SAFE MODE...
use the phone for a bit and see if it gets warm... this should tell you if its apps installed.
I only used wifi, no tethering, no GPS, 3G, NFC or any other radios, cell signal is good so phone is not searching for it.
- In safe mode, it still gets warm when using camera. When browsing internet and watching images in google search, also but just mild warm..
- But after sitting and thinking, I've found a problem! After recording with camera and leaving it to cool down, it didn't cool down because it had to make an effort to upload that 5 min video on Google drive via Auto backup!
After turning the Auto-backup off, it is now much cooler!
I will post tomorrow with the results, if something changes...
Anyway, thank you!
First of all, "warm" doesn't mean anything.
Battery temperature does not mean much either, as the CPU is what generates the most heat.
There is a battery temperature throttle that reduces the CPU frequency, but it is almost entirely pointless as the CPU will always reach it's own throttle temperatures MUCH, MUCH earlier than the battery will. The CPU starts throttling at 65C CPU temp (NOT battery temp), and shuts itself down at about 105C CPU temp. Unless your battery somehow reaches a batterytemp of 70C+ (nearly impossible because the CPU will always hit it's throttle first), then I would never even take it into any sort of consideration unless you have a physical battery defect.
Using the camera generates heat since it's CPU and power intensive.
Using the phone in general will generate heat.
Keep in mind that mobile devices are passively cooled, not actively cooled with a fan/liquid.
Not sure what you're so worried about.
Lower your brightness
Lethargy, thank you for a short physics lesson. I'm already into physics and cooling systems so all is clear. I was just worried a bit because all of my previous phones weren't getting this warm (hot), but also never had a multi-core processor in phone eather, maybe that's the reason why I never experienced this before.
Battery temp (measured with app) gets up to 40-42 degrees Celsius, while the phone case gets up to 41 when recording video. Of course that temp won't damage the device, I'm not worried about the processor, but that temp is degrading battery life, in long term.
And about the brightness, phone is not meant to be used at lowest brightness all the time, so that shouldn't be an excuse for high temps. Just sayin'...

The only thing that sounded odd was how it wasn't cooling down until you rebooted, but it sounds like you figured that out with the automatic upload setting.
41-42c battery temp can be normal after prolonged usage, though personally I usually see that after a short gaming session. My brightness is around 40% and high brightness will cause extra heat.
Otherwise the phone is very thin so you can feel the stacked SoC and RAM heat up through the skin fairly easily, right around the camera area as you mentioned.
I think each device and CPU is slightly different and can vary by a few degrees under load as well.

Your temperatures are fine and you shouldn't worry about it. It's average for a Nexus 5, and there are throttles/shutdown temps anyways, for both the battery and CPU. I've had mine for a year and there hasn't been any sort of issue, normal usage should be negligible to the condition of the battery.
Ok, everything seems to be ok then. Now I can go to sleep without worrying Thanks guys!

Nexus 5 CPU is extremely hot

Hey all,
As of about a month ago, my beloved Nexus 5 has been getting extremely hot to the touch. As a result of that, the device is uncomfortable to handle and is dying quite quickly. As this was a factory refurbished I got from eBay, I had no warranty on it. I read a thread on here awhile ago that Thermal Paste could help with heat on the CPU, so I decided to try that as I didn't have a warranty to void. That did help with the temperature on the CPU, but because Thermal Paste is a conductor, all the heat dissipated into the screen, essentially making the screen a mini stove. I then heard that Thermal Pads might work better, so I ordered some off of Amazon and applied them to my CPU. This helped with idle temperatures, but as soon as I touched the screen they raised back up again. I've tried everything, CyanogenMod 12.1, CyanogenMod 13, CAF ROMs, and I even flashed it back to stock. Nothing works.
Now for the odd thing: Idle Temperatures are normal, at around 38°C. Load Temperatures are fine, it reaches around 65°C under AnTuTu's Stress Test. However, under normal use such as browsing Chrome or watching YouTube, the Temperature IMMEDIATELY goes from Idle up to about 58 °C, and stays there. The phone loses battery rapidly, and it burns my hand using it. I've checked for CPU hogging apps, there were none. I made sure I was on the correct CPU Governor, and I was. Even on the Conservative Governor the Temperature was still going up to 58° C.
I have no idea what is going on. I might have an idea, but I don't know if it's even how the phone would work. My battery has been acting up lately, even before the phone started heating up. Some of the times when I've taken the phone apart, I noticed that the Battery's Ribbon Cable sparked a bit. With this and the fact the the battery has been acting up, it leads me to believe the the battery might be unstable. Could the battery be delivering too much power/voltage to the CPU, causing it to heat up? Just a wild guess
Help would be extremely appreciated
its battery issue. try changing it
