I seen in the owners manual not to charge the battery with the temp over 113F but at what temp is the critical operating threshold for the epic? I've seen mine up to 120F while talking on bt and charging really get's this phone hot, happens to me often.

I have a feeling that the battery temp reading we see on our phones is actually the cpu temp or motherboard temp
I ran setcpu stress-test for about 30 minutes (phone unplugged) and the temperature got to nearly 50 degrees Celcius
Feeling the top middle area on the back of the phone (and the same area on the screen on the opposite side) that area feels hot, the battery however is stone cold.
So... Battery Temp = cpu temp?
Anyone got an opinion on this? Its important for the overclocking crowd

I can tell for sure that battery and CPU temps is always the same but where is the sensor?? On the battery or the CPU?
If I was designing this phone I would put it on the CPU as it is more likely to produce heat if overused.
However I just experience a drastic temp raise from 33C to 41C in 1 min just after pluging in the phone. I was using it but noting eavy. I was only changing some startup setting with an app called Autorun Manager. So it might be related to battery but according to what you said it is more likely to be located on the CPU.
I currently have one of those extended batteries and tmeperature rises to 52 C after 10-15 min of playing gameloft hd games. I have measured phone temperature with an infra red thermometer and battery was 30-32 degree and upper part of the phone (between sim card and camera seemed to be as high as 49 degree) so the sensor must be on the cpu or motherboard, not anywhere close to the battery.
Unless battery gets hot inside and is cold outside for some reason. And sensor is simply inside the battery like in a laptop battery (google: 'How Lithium-ion Batteries Work' and open first result)
In my personal opinion manufacturers wouldn't waste space inside the battery for additional sensor that looks pretty big on the website above. Furthermore a hot battery would be hot throughout its casing too.
Which sensor you people are talking about?

Temperature sensor. Download temp+cpu from store and you'll know
had my phone charging of my usb on my laptop last night while i was texting a friend, when i noticed that the the Kick stand was getting warm so i checked the temp through my battery widget and found the temp to be 114.5* F I immediatly unplugged my phone and took my case off and the back off to let it cool. I was wondering if this is common or even a safe temp. My setup is as follows
Azrael X 3.1
Net's 2.3 more aggressive universal havs NO SBC
Amon RA 1.8
Max temp for the battery is 60C/140F. I have had temps in that range if I had the screen on for a long time or wifi tether. Around 50/55C though and I would worry.if you notice it often and overclock then I would lower the max cpu frequency.

Thanks for the response on this i'm not overclocked so i guess it was the screen being on to long. I will keep a close eye on it from here on out

You are definitely within safe limits on temperature. The only bad thing is the batteries capacity degrades quicker when at a high temperature, but you will probably replace the phone prior to actually realizing the degradation.
Its fine. Mines been a little higher. I don't like using my phone around those temperatures though.

I've read 120 F as safe. So it's close.
General consensus is that using the phone while on USB tends to yield higher temps, but no one knows why.
I am getting bothered by the heat of my nexus 4 especially at the camera side..., when I play psx emulator it really gets hot and it gets hotter when it is charging... even if i am only watching or streaming the internet it gets noticeably hot, so i would like to know if this is ok or not.
what are apps that could monitor the temperature?
what is the normal temperature when gaming and idle?
I would like to know about this things so that if my unit is a lemon, i could return it to lg for the warranty.
thanks in advance.

you have a quad core device, its normal. when you stress the cpu, gaming, streaming, itll heat up. when you charge, your battery will heat up. the back o the phone is glass, so itll feel like it gets hot fast. when the device hits a certain cpu temperature, heat throttling kicks in. this will lower your cpu speed and cool down your device. when it goes over the cpu safety temperature(100C i believe), the cpu will shut down and the phone will power off. there are several apps that show the cpu and battery temperature. remember, battery temperature and cpu temperature are two completely different temperature readings.
System tuner gives you cpu temp. But you should get an app that tells you battery temp as well...

ok thanks..., I'll monitor my device and post the temperature later.

simms22 is right you can under clock it safely kernel tuner is free on play
Intel CPUs (i5, i7, etc.) can survive going over 100 degree Celsius, but the commonly quoted safe temperature limit for long term operation is 70 degree Celsius. I would assume that the same holds true for other silicon chips, and find it difficult to believe that the shut off temperature for the Nexus 4 is 100 degree Celsius - you will be getting serious burns on your fingers by then.
Wait..., I recently played a 3d game and my temperature is reaching
CPU: 67c
Battery: 50c
Is my phone a lemon or its a normal case scenario?
Hi all,
For "hardcore user" there is a thread with a solution to limit the heating :

Is this temperature normal??
That is a little worrying. Are you using a case? Also what is the room temperature where you were using the phone?

sorry for the late reply I thought no ones going to reply with my post, the room temperature is 31c. and I dont use a case
With normal tasks such as browser, phone and messaging, the CPU temp of my phone is around 38-40. With tasks as YouTube and graphics intense games it's between 50-55. At this point, the phone feels really hot.
Are these expected temp level or is there some problem with my phone?
With asphalt, the temp averaged around 65C. While downloading the additional content it reached 75C.
I rarely see mine above 45. I've only seen 50 a few times. Throttling kicks in bad above 50

How can i check the temp of the CPU? Most of the apps don't even show temperature on 6P and CPU Z gives me like 15 different readings ;/
For this I had used CPU Temp. But yeah after the update, it says that it cannot determine the temperature.
In CPU Z, I was unable to understand the readings. One of the app, said that there is no temperature sensor to determine the reading of the phone. So not sure if we can get the accurate temperature.
But the phone is for sure getting too hot. I feel Nexus 6p has heating issue, or atleast mine does.
45-60 shouldn't damage your CPU, but 75+ can be harming for phone's integrated circuit

Remember that it will go up to 70°C maybe higher and the aluminium case spreads the heat making the whole device hot (LG G3 was very hot only in specific area, because it was plastic).
Is anyone else having issues where they're phone locks at 600mhz and is laggy as hell?I've tried multiple Roms even stock and get the same situation..It seems that if I try to charge my phone at all this gets triggered.
apparently charging and quick charging throttles it I believe...quick charging even worse. that's pretty hot for a battery temp so yeah probably throttles.

I get the same problem even it is not charging. When battery temperature approach 40 degree,sometimes 38. The cpu scaling is locked and capped below 652MHz and become so slow to use!! It happen indoor and outdoor, so annoying
