Prevent shutdown due to high temperature - General Questions and Answers

I am using xperia sl with cm12.1
I think temperature sensor in my phone is damaged and it shows very high temperature even though phone is very cool. (when I connect to charger it works fine)
So my question is, Is there any way (or modification of any file related to temperature) to prevent my phone due to high temperature warning!?
This happens on stock xperia rom, too.

[Q] Samsung Galaxy note 2 High Temperature

Hi,
In my galaxy note 2, when i see the temperature using *#0228#, it shows that battery temperature is 35`C and temperature of external thermistor is 55'C. What is external thermistor ?? Also, what is the reason of its high temperature and will it cause any harm to the phone ??
Also, is there any solution to this problem ??
Because of this high temperature, when i open camera, it shows an error "Flash has been temporarily turned of because device temperature is too high"

Generally higher temperatures is due to a too heavy load on the processor.
I advise you to download batteri saver which enables you to see which application is heat your battery

I have tried every possible application and I also factory reseted the phone hoping that it would solve the problem but all in vain.

Back panel heating

Hello guys,
Guys post your battery temp during normal use,gaming,heavy app use plz..m facing heating issues and want to compare with other Xperia L's
This is during my normal use with 3G which heats upto 40 sometimes
Screenshot attached
Normal Usage using Wifi
Normal usage with wifi:
After playing around 10 minutes of Asphalt 8 on High settings:
The CPU was at 50 degress but it goes to 48 when I took ss.

Mine goes 42 degrees with gaming like FIFA12 etc and in 3G use it stays around 35-40 and with wifi 34-38..are this temperatures normal?

I cannot said what the temperature is when I use 3G as my data package is out for this month already, but I think the temperatures provided by you are normal. Like when you are playing Fifa the CPU is cooler than mine. I think they are normal. Most of modern phone's have heating issue during playing.

Hmm but i rarely play games ..also sometimes temperatures rises during charging period with moderate use while charging and battery temperature reaches 43 degrees..is this harmful? Well i think its harmful..

Well, don't think so. My phone also heats up during charging when I use it. I'm not sure if this work or not but you of course when you wan't can enable option that Nexus 4 has. It's like when a phone reach certain temperature a cpu/gpu clock is lower to prevent battery overheated.
I don't have it enable as mostly I don't play or do anything more stressful that will make phone hot.

dude you have a fit right...oh you sold it, still that device was about half as powerful okay 1/3 rd yet the battery temp with 0 activity and mostly in deep sleep is at 30 C.
now xperia L is way more powerful so should get a tad bit hotter too right(of course that's based on CPU activity) try it put is down for say two hours no charging , no nothing so that in deep sleep(lowest freq) also no 3g(that has its own daemon that eats cpu power i.e. causes cpu to work and hence battery drain and heat). wifi is okay(stable connection hence minimal cpu usage as no reconnections).
now check yor battery temp should be around 35C so your device is fine.
all this is based on stock heat and power management cant comment on custom kernels.

if you are on a custom kernel the best practice is to uv and NOT oc also change the governor to Interactive since thats far better than performance.(spimply put performance goes to top cpu freq even when not required and slowly scales down while interactive scales up fast and down fast at user touch events) for heating and basic phone wear and tear purposes.
and one of the main reason along with more ram(i mean lower bloat hence more free ram) that i want a cyanogen mod ROM.
Before and after playing candy crush.lol
When charging,it will up to 37-39 degrees
Qualcomm makes the MSM8230 chip that you see in L, there are 4 different "types" based on how it meets their quality standards. These are Slow, Nominal and Fast (Faster is on Higher end chips like APQ8064). The main difference IIRC between these types is how stable each can handle undervolting. CPUs that are "Fast" for example come pre-configured at a lower nominal voltage than a "Nominal" type CPU, and more so than a "Slow" type. IIRC, there's like only a -50mV difference between Fast and Slow out of the box, however Fast CPUs should be able to handle lower voltages than Slow-type.
This may explain why some people complain higher temp than others on account of same tasks. Although there can be other reasons. I'm not quite sure.
To find out what binned CPU you have, I recommend the following:
YOU MUST BE ROOTED! And installed busybox
1) Install Terminal Emulator
2) Reboot your phone
3) Open Terminal Emulator, and type:
su
dmesg | grep PVS
(if you don't see anything, try it.immediately after fresh reboot)
For example I've fast binned cpu
So basically, far as I understand I got Fast CPU which isn't going to be as hot as the Slow type due to lower voltage ?

then go for ondemand the performance might be a tad bit slower than preformance governor but your battery life should be better along with the heating...also no oc.

Ya bro i also face the same..when i use my phone during charge time..and normally it is about 35-40. @Dark Passenger what are stats about your XL? Can u post it here?

I have a fast binned CPU
The result number shows the characteristic of cpu binned (AFAIK) Source : http://www.oppoforums.com/threads/qualcomm-cpu-binning-is-yours-slow-nominal-fast-or-faster.2842/page-5
1 : slow
2: normal
3: fast
4: faster

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?
Sent from my Evita
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.

Phone heat

Hello I have noticed with the new update my phone heats up a lot during normal use.
This never happened with the 4.4.2 nor the 4.4.3
Is this an issue that many have dealth with? And will Google address this as well?
by the way Im on stock
Heat is normal. If you feel as though it is abnormally hot you should download GSAM or another app which measures temp and post your results.

Could it just be warm weather? Even when idle, the phone can never be cooler than the ambient temperature around it.
Somewhat normal. Custom kernel's can help...
Its Normal, all high middle models of smartphones getting heat temp, if temp is to high CPU thermal throttling cut down actual frequency

what temperature does your note pro get to in power saving mode?

my note pro 12.2 temperature gets quite high 40C when using it even if the conditions are relatively cold outside is this normal?
my samsung s3 would heat up too that's why i never closed the cover properly to let the hot air escape.. this made a big difference as it wouldn't go up past 32C even in warmish indoor environments (also i used power saving and lowest brightness). i apply the same principles to the tablet, power saving, lowest brightness or auto brightness yet the top part by the camera at the back i can feel heating up and is quite warm.. is this normal? do you other guys have high temps?
i read a review saying it doesn't really go above 35.6C which is BS as mine goes to 40C. i know because the cover is not open the hot air cant escape so the CPU is running up or the battery is heating up or maybe both. i use OS monitor to monitor my battery temp and voltage.
do i have a defective unit possibly? this might also explain why it reboots randomly however i know for certain when it rebooted the temperature was low as i was using it in like 4C conditions so the temp was under 30C max however now the temperature outside has risen i think that's playing a part. im getting sick of all these samsung issues. their quality control needs to be better or at least create so air vents so the battery can breathe. temperature kills lithium ion and i dont think you can change this battery easily

What you're reading is battery temp, not cpu temp. 45c and below is perfectly fine. As for cpu temp, gaming can bump that up to 80-85c. Thermal shutdown occurs at 105c (SM-P900)
