Overheating - ONE Q&A, Help & Troubleshooting

I notice the top of the phone gets really hot when I play games. So far I've only been testing plants vs zombies 2 with a cpu temp app and the cpu temp averages at 62 celsius which is fine on a cold day. However, on a warm day it tends peaks into the 70s and my cpu temp alarm goes off and I can't play more than a few minutes. I've tried to use powersave mode to lower the clock speed and it doesn't make a difference. I think the sandstone backing doesn't dissipate heat as well as a normal plastic/metal backing. I know the cpu is supposed to have thermal throttling, but I'm wondering if there are any non-stock kernels that may have a more aggressive thermal throttle.

Flash CM11 and a costum kernel. Any of them will let you over and underclock, over and undervolt, raise or lower throttling, but not on stock rom.

still overheating
I've flushed CM11 stockrom.
Now when i use waze and charge the opo it gets overheated too.
+ the touch won't work correctly.
Is there another way to stop this?

Steps to fixing overheat?

Hello all
My Galaxy Note runs hot.
Can someone tell me, preferably in methodical order, the steps that should be followed to sort out overheating issues.
If you watch the Australian Open tennis then you will see how hot it gets here in summer at the moment!
1. Root
2. Install SetCPU
3. Set some temperature profiles so when your Note reaches a certain temperature the clock speed is automatically dropped
4. Close unused apps and stuff
5. Don't use 100% brightness
If I was you, I would use, in fact, lowest brightness when indoors, and underclock the CPU (even when it's not hot, as opposed to what vantt1 says).
I underclocked my Sensation from 1'5 Ghz to 1'0 Ghz (both cores). And boy, It's running smooth with ICS, no lag at all.
In fact, my settings are:
Min clock: 192 Mhz
Max clock 1005 Mhz (or something around that)
Governor: Ondemand
But your CPU is probably different than mine... Keep in mind that I underclocked around 30% of it's total capacity. You might want to do the same.
Also, direct sunlight causes overheating. (Might be obvious, but when the sun hits our skin, the body starts several cooling methods, so that you only start to notice the overheating around 30 minutes of direct exposure... And 30 mins of direct sunlight for a phone is a total kill, so also one more tip for when you're on the beach: cover it with clothes, or something. It will also decrease posibilities of thieves )
My Galaxy S2 doesn't really overheat when clocked at 1.4 GHz ondemand. It's the maximum safe clock for the Exynos 4210 found in the S2 and Note. The speed is there when I need it (but that's only 2% of the time) and when I don't, it's around 200-800 MHz. I have a solid aluminium case on it, so when left on the table it can go down to 25°C. In my pocket it's a bit higher at 34°C but it's acceptable. When I play GTA3 though, it can go up to 56°.

force reboot of phone isn't always overheat. the kernel also depends on how high you can overclock.

[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.

[Q] Heat and low perfiormance

Got My N5 today, its awesome,
Looks like the performance is so so, the phone heats up too quickly and CPU performance goes down,
If I do Antutu when its warm I get less than 20K in it
If I let it rest for some time and then do it I get a score of 25+
Looks like the device has heat issues
are you guys facing the same issues?
Two-part solution: Stop running benchmark tests and flash Franco kernel.
And, search before you post. Lots of threads on performance benchmarks
I see so many people who care what a benchmark score is.

its not a heat issue. it will get hot with use, especially with antutu benchmark, its a 2.3ghz quad core phone without an active cooling system, what do you expect? anyways, the reason performance goes down when hot is because of heat throttling. your phone does this when going over a certain temp. it drops the cpu speed and number of cores used until it cools down. there are ways around this. you can root your phone and flash a kernel that lets you disable thermal throttle. then all your left with is the safety reboot temp of 100C. when reaching this temp, the phone will automatically shut down. or you can put your phone into a freezer until the cpu temp is below 10C, then run the benchmark.

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)

S6 CPU temp is 55-60 degrees under light use

Battery temp and health is good. Battery usage doesn't have anything out of the ordinary. What could cause these high temps?
As far as I know, normal temps under light to normal use is 30-40 degrees
Eh, I get similar readings on both my S6 and my ex-S6 Edge. It doesn't feel as hot as stated by the sensors on the outside. I guess, Samsung didn't calibrate them properly.
Bottom line, it's your normal and your phone will be fine.
That's normal. And those are calibrated correctly by the way.
CPU is somewhere in your device with some heat spreader on it that's why you don't feel holding a 60C phone in your palm.
You should be more sensitive to battery temp rather than CPU temp because CPU can run perfectly fine up to 75C; But for battery, anything higher than 40C is very destructive.
However if your phone feels uncomfortable in your hand (Like mine) try flashing Arter97 Kernel or AEL Kernel and undervolt. The lower the voltages, the lower heat will be. Without in sacrifice in performance!
My normal use temps were around 55-60 like you. After undervolting for -125 mV it barely crosses 52C. Most times it jumps up & down between 45-52.
