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.

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.
I have two questions.
My Nexus' battery tends to overheat whenever I'm either playing games or charging. From what I've read, a hot battery will shorten the lifespan of the battery. What method do you use to cool down your battery?
This is a simple solution I came up with:
1. Take out an ice pack.
2. Envelop the ice pack with some sort of thin cloth (I used a microfiber cloth).
3. Take out the phone from its case and place the phone on the cloth.
I'm rather concerned about this method because it does cause condensation. However, the cloth applied over the ice pack is supposed to absorb the moisture emitted from the ice pack. Thoughts on this?
Hi,
First thing: can you provide the real temperature instead of saying "overheat" (it's like "it feels hot, warm, very hot, etc...")?
Second: are you sure you are speaking of battery temp and not CPU temp?
Phisically where your device is "overheating" (bottom, center, top right)?
what do you consider "overheat"? how it feels in hand isnt an accurate way to measure temp, as it could feel hot but still actually be cool. while charging, its normal and expected to get warmer. also while charging and using the device it can get significantly warmer. and the chances are that you will long get rid of your nexus before you see any real noticeable battery loss(2-3 years +).
Sure, sorry about that. I'll specify more in this post.
The heat is coming from where the battery is located and it feels very warm.
My phone went all the way up to 46C. (After cooling it off, it's 25C)
As for the CPU or battery temperature, the app I use only states "temperature: ". I'm assuming. it's battery temperature since the app monitors my battery statistics.

46C is normal for battery temp, especially while charging(its not that much higher than body temp, which is 37C). if getting up around 55-56C, then its getting a bit too warm. 60C is overheating for the battery(100C for the cpu).
Nothing to add much as what simms22 said, in any case there is a thermal protection (thermal throttling) and the last protection is a shutdown (for both about CPU and battery temp)...
We have a quadcore device enclosed without any "hardware" cooling system, so under some conditions you can expect some heat, nothing to worry about since there is a thermal protection.
You are on stock kernel? What is your room temperature?
To me your solution seems too extreme and useless ("an ice pack", all day, near you, ready to use it when you reach YOUR temp , stop using your phone in this case...) , search for "heat" in this forum, nothing wrong.
While charging I have something like 39/41 °C and if I use my phone it can go at about 44/45°C for the battery temp. For the CPU temp while charging it can go to 70°C (all browsing the web in Wi-Fi and in 4G it's more, 88°C but with custom kernel and custom thermal settings).
Honestly, your use phone like you want and like you need, don't bother, in any case if you have a real overheat you will know (see above)...
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?
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)
I've noticed that on heavy usage the cpu temp raises up to 41C with core control or about 45C without offline cores. These temps are quite OK for the 808 however the touchscreen in front of the SoC is too hot even with 40C but the back cover is OK. Other devices tend to go above 50C without too much heat on hand. Have you the same problem?
The top front does get noticeably hot yes. I don't know if that's a problem. All seems within normal operating temperatures. Guess it might be slightly uncomfortable to the touch.
I think the reason you typically don't feel it on other phones is because the screen is usually indented a bit deeper and the digitizer is usually thicker glass.
Me too I'm also worried is it okay for the hardware ? Or it will it get damaged because at 41°C the phone becomes really hot

If you're worried about hardware failure, you would need about double that temperature to get into the danger zone.
The phone has temperature control built in, so you shouldn't have to worry about operating temperatures unless you're leaving it out in the Sahara or something
After watching a tear down, it seems that they designed it like this. The SoC is placed on a metal frame above the LCD so it can dissipate the heat quickly because of the glass.

40 isn't that hot.
Mine goes up to 69 that is insane hot.
With Max brightness while gaming.
Thermal tweaks didn't help.

You are so lucky....mone just thermal throttling and fps in games drops to 10-15
