Hi all. Since I've looked for but didn't find a clear topic about this (sorry if I've missed it), I thought it is a good idea to see which are the normal working temperature ranges for our Legend (especially if you're overclocked).
Someone on this forum was trying to draw my attention that my temperature was (or is going to be) too high (saw it from one of the print screen I've posted in that topic), so I was wondering what should be a "normal" temperature.
Usually for my Legend the range is between 30 - 38 C degrees, the upper values when it's charging (as I understood it is normal), having a 34-35 when not charging and in use. I got as low as 22 C degrees in the morning when the phone was not touched for the whole night, but as soon as I'm using it, temperature is increasing.
I'm using a CM nightly build, OC 806 (kernel) and I was wondering if a 33-38 C degrees temperature is normal or I should overclock it a little bit lower (OC 787 for ex.)
Should I make any worries?

I just tried over-clocking my new Gene (P3400) today, and it feels good. I also saw that the temperature (shown by BatteryStatus) has increased from earlier about 27-28 to current 33, and its night and the weather isn't hot here (yet).
So I was wondering what's the average temperature you should be getting and where should you draw a line and decide to run back.
By the way I've tried to be in the safe zone and OC'd upto 247mhz only.
Thanks!
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
what are the normal battery temp levels for the galaxy tab? Mine goes from around 28 deg Celsius idle to 43 deg Celsius when charging or prolonged use. Are these safe operating levels or is it getting too hot? At 40 degrees i can already feel the back panel getting warm so im a bit worried about the processor. Im not overclocked and even undervolted by 100mV.

Trust me, samsung is giving us all a total headache. For once, my battery temperature went to 53degrees Celsius. I laughed so badly when i saw that.

Just curious, is your battery charging and discharging normally?
Mine's going from 14'C (outdoors) to 35'C max. (playing while pluged). Normal voltage.

The most mine ever goes to is about 36 C. both in use and in charging. Overclocked to 1.2ghz
It chatges and discharges normally, i get abot 26-30 hours out of it with average use. I do live in the Philippines though so that may be the normal temp for me. Just want to know what the danger zone is for his device when it cones to temperature.

Mine goes to 37 38 @and 27 idle

Normally it is within range between 27-28 and 38 (C) on my overclocked up to 1.2GHz . When charging and running in the same time - temperature may be a bit higher, because the battery becomes warmer during charging. Important factor is software used for measuring, I use 2 different applications and always compare the readings.
Hi,i'm new here and sorry for my bad english
I'm on PA 3.1 and since PA's base upgraded from 4.2.1 to 4.2.2,my nexus 7's bottom left corner got warm and hot than normal,CPU temperature is usually at 36-37 °C,even when i just browsing/reading
I just want to know if anyone here got the same issue as i got
Thank you and sorry again for my bad grammar
I did the same jump as you from PA 4.2.1 to 4.2.2. I haven't had any heat issues at all. Mind you I have undervolted 50v across the board. It might be a rogue app.

what kernel do you use?
37-38 C is nowhere near to being high (if you are indeed talking about the processor Tj)
The stock kernel does a panic shutdown at 100 C, and rate throttles a little below that. (At the moment I can't remember if that happens at 95C or 90C).
That Tj temperature is measured by a circuit embedded in the face of the SoC chip itself, so it is literally the hottest place in the whole device.
I have run native multithreaded stress test codes simulaneously with OpenGL benchmarks, and while the lower left corner of the tablet gets warm, the maximum Tj I observed was about 85C (Stock kernel - no GPU or CPU OC'ing). When "idle" such as reading web pages, my stock device sits around 38C as well.
The only thing that is disconcerting about what you report is that you mention a warm tablet in conjunction with 38C. That shouldn't be the case unless you made the temperature measurement substantially later that the CPU/GPU load which created the temperature spike.
Remember that there is a substantial delay between a peak temperature felt through the case and when the CPU goes up to high temperature. In my experience, it takes several minutes of maxing out the processor(s) before you start to to notice that "lower left corner" hot spot. So if you are observing that behavior regularly, you do have a reason to be concerned.
good luck

I'm sorry,its 60C,not 36
I have mistake CPU temperature with battery temperature

Understood. I should have said "cat /sys/kernel/debug/tegra_thermal/temp_tj" to be clear.
60 C does seem a bit high for a N7 which is supposed to be doing very little work.
Mine (stock jdq39) is sitting here doing nothing but with the screen on (plugged into USB), not charging and it is about 42-43 C.
The effects of heat are cumulative - you should look into it.
Before I call up EE and ask for a replacement I would just like to check if these temps are normal and if anyone else can run the same test and check what there temp gets to on the Note 4.
Firstly my Note 4 idles at around 36 degrees C which is pretty normal from what I can see. When running the Epic Citadel Benchmark on max Quality the Temperature reached a very hot 77 degrees C before I decided to stop it and shut it down.
It also reaches temps above 70 degrees C in Grand Theft Auto Vice City aswell on max settings.
Could a couple of you guys with the Note 4 please download and run the Epic Citadel Benchmark.... and use the CpuTemp app to measure the CPU temp while its running. This app has an overlay feature so you can watch the temp while the benchmark is running and I would love to know what the max temperature is that it reaches during it so I know if my phone is normal or faulty.
I get a score of about 52fps but the temperature just seems to high to me even though my idle temp is normal.
it would be very much aprechiated thank you.
That sounds about right. I just downloaded it and ran the benchmark on High Performance and got 56.4 FPS avg and the temp was around 52 degrees (started at idle, which was about 35, 36 degrees). Actually it basically spent most of its time during the benchmark at 1.5 GHz and just over 50 degrees. Then I let it cool down a bit and ran it again on Ultra High Quality and got a 48.9 FPS avg and the temp was around 77-78 degrees, spiking to around 80, but even at 80 degrees it was still fully clocked at 2.7 GHz.
But at least for me I notice even when using a couple pop up windows to play a youtube video (music, static image) while browsing Facebook and having Messenger chat heads up that the phone heats up quite a bit, going towards and around 70 degrees the more FB posts I go down and I can see it mostly around 1.5 GHz but it's still stuttery. I use CPU temp and frequency in status bar from XPosed Framework so I did have to keep dragging the status bar down to check. I'm curious what the scrolling performance would be like using ART instead but I'd have to give up XPosed and I don't think I'm ready to do that yet.
