cpu temperature using system tuner - Galaxy S 4 Q&A, Help & Troubleshooting

Im just curious what temperature you guys are getting on idle and heavy load such as antutu.
Lowest i get with idle is 40c degrees celcius and 50c with general use browser etc but with antutu i get up to 70c+ and then shutsdown.
I monitor it with system tuner and notification packages so i can monitor it real time with app usage.

Battery Temps

What's an unsafe battery temp?....I was using Wireless Tether with MIUI and noticed my phone was hot, I looked and it said 44 *C and 111*F is this bad??
im running MIUI as well, and when i use wireless tethering for a while, itll get up to 42C+, but my SetCPU profile will set the CPU to 245mhz when the temp hits 42C or above.
So I'm guessing 42 is the max temperature to run your phone? or is that still unsafe?

Battery Temperature Norms

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.

[Q] Nexus 4 heat problem

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.
Idle
batt: 35c

I'm still downloading a heavy intensive game to test

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

Very high temps when gaming/benchmarking are these normal?

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.

Real CPU temp

Hi everyone,
Today my S4 gets overheated so I installed app to control CPU temp, but can someone tell me what is a real CPU temp? Coz two apps shows me different values.
CPUTemp is on overlay and Cool Master is on main window. What app shows real temp? And my CPU temp is ok? Coz I wasnt using any heavy app when getting screenshot, its normal state.
Sent from my GT-I9505 using XDA Free mobile app
I have bigger difference using same apps.
on standby cputemp app shows ~30. Simple browsing - 40. Candycrush gaming or intensive browsing - 50-60 degrees.
Cool master shows almost -30 degrees too. Don't know if any of them shows correct temperature. I believe cputemp results are more accurate
