CPU Temperatures - Samsung Galaxy S7 Questions and Answers

Hi I was just wondering should I be worried, I was messing around with my phone tweaking it and installing a few mods and my CPU temperature went all the way up to 38 degrees Celsius, I'm not sure if this is normal or not? Please respond

if you install mod to boost performance or overclock cpu you should expect higher temperature.
however 38 c is not too high. have you tested temperature before those modifications?
specify mods you install to get better help :good:

I was only modding the UI with substratum etc, it seems to be getting quite hot though, I'll leave it for today and if it doesn't go down I might wipe my phone

How did you read-out the CPU temperatures?
Becaus 38c CPU is really low if you do heavy use your phone.
the temperature could possibly be the battery...
use this App to check the real temperatures... and don´t be afraid.. CPU rises upt to about 75C

I got it from the temperature reading in TWRP? Is that the CPU temperature?

No.. its the temp of the battery..

Hello guys,
Guys post your battery temp during normal use,gaming,heavy app use plz..m facing heating issues and want to compare with other Xperia L's
This is during my normal use with 3G which heats upto 40 sometimes
Screenshot attached
Normal Usage using Wifi
Normal usage with wifi:
After playing around 10 minutes of Asphalt 8 on High settings:
The CPU was at 50 degress but it goes to 48 when I took ss.

Mine goes 42 degrees with gaming like FIFA12 etc and in 3G use it stays around 35-40 and with wifi 34-38..are this temperatures normal?

I cannot said what the temperature is when I use 3G as my data package is out for this month already, but I think the temperatures provided by you are normal. Like when you are playing Fifa the CPU is cooler than mine. I think they are normal. Most of modern phone's have heating issue during playing.

Well, don't think so. My phone also heats up during charging when I use it. I'm not sure if this work or not but you of course when you wan't can enable option that Nexus 4 has. It's like when a phone reach certain temperature a cpu/gpu clock is lower to prevent battery overheated.
I don't have it enable as mostly I don't play or do anything more stressful that will make phone hot.

dude you have a fit right...oh you sold it, still that device was about half as powerful okay 1/3 rd yet the battery temp with 0 activity and mostly in deep sleep is at 30 C.
now xperia L is way more powerful so should get a tad bit hotter too right(of course that's based on CPU activity) try it put is down for say two hours no charging , no nothing so that in deep sleep(lowest freq) also no 3g(that has its own daemon that eats cpu power i.e. causes cpu to work and hence battery drain and heat). wifi is okay(stable connection hence minimal cpu usage as no reconnections).
now check yor battery temp should be around 35C so your device is fine.
all this is based on stock heat and power management cant comment on custom kernels.

if you are on a custom kernel the best practice is to uv and NOT oc also change the governor to Interactive since thats far better than performance.(spimply put performance goes to top cpu freq even when not required and slowly scales down while interactive scales up fast and down fast at user touch events) for heating and basic phone wear and tear purposes.
and one of the main reason along with more ram(i mean lower bloat hence more free ram) that i want a cyanogen mod ROM.
Before and after playing candy crush.lol
When charging,it will up to 37-39 degrees
Qualcomm makes the MSM8230 chip that you see in L, there are 4 different "types" based on how it meets their quality standards. These are Slow, Nominal and Fast (Faster is on Higher end chips like APQ8064). The main difference IIRC between these types is how stable each can handle undervolting. CPUs that are "Fast" for example come pre-configured at a lower nominal voltage than a "Nominal" type CPU, and more so than a "Slow" type. IIRC, there's like only a -50mV difference between Fast and Slow out of the box, however Fast CPUs should be able to handle lower voltages than Slow-type.
This may explain why some people complain higher temp than others on account of same tasks. Although there can be other reasons. I'm not quite sure.
To find out what binned CPU you have, I recommend the following:
YOU MUST BE ROOTED! And installed busybox
1) Install Terminal Emulator
2) Reboot your phone
3) Open Terminal Emulator, and type:
su
dmesg | grep PVS
(if you don't see anything, try it.immediately after fresh reboot)
For example I've fast binned cpu
So basically, far as I understand I got Fast CPU which isn't going to be as hot as the Slow type due to lower voltage ?

then go for ondemand the performance might be a tad bit slower than preformance governor but your battery life should be better along with the heating...also no oc.

[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.

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?

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.

66° Celsius. seriously and that too the battery?

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.

That doesn't tell us anything. Get an actual battery temperature reading, not what you think it feels like. Most kernel apps should tell you.

I don't pay attention to it myself since I know it isn't overheating. Various kernel apps should give you a reading, hell even Antutu Benchmark tells you your battery temperature in Device Info.
Also, when your battery reaches 60C (or 65C, forgot which of the two), your phone will force shut itself off. Chances are, you're not even feeling much heat from the battery, the CPU usually produces more heat before the battery can even reach that high (some kernels have battery shutdown disabled anyways). The CPU starts throttling at around 60C CPU temp (NOT battery temp), and force shuts down at 105C. Clearly, "warm" is no issue at all.

Thermal throttling and hotplug settings

I have been able to fix quite a bit of thermal throttling experienced in multiple benchmark runs by tweaking with the thermal-engine configuration file. With just a few changes and with the copper shim mod I can now run geekbench for as many five times with almost no drop in score. After that I get no thermal throttling in single core but I have it setup to disable two cores after it hits 55C CPU temp in core 4 and 7. I use CPU Z to see actual CPU temp from the sensor readings. Even after 8 Geekbench runs the two cores are still running at full speed and the phone is registering 44C. It's warm but not hot by any means.
If anyone is interested in playing around with it just look for the file in \System\etc\thermal-engine-8994.conf
Most of it is just two adjustments. One for Max temperature at which it will throttle and the one below is the temperature at which throttling stops.

Without your copper shim mod have you found any better but safe values we can try?
At least no thermal throttle until 55 celsiius
It should be safe without the copper shim. The thermal pad it comes with works pretty well. It will still thermal throttle to whatever temperature you set it at so it won't cause any harm.
I've set the Big cluster to a max of 65C and a single A57 core to up to 71C and haven't had any problems yet. I used to get horrible performance with PPSSPP emulator. When running Tony Hawk Project 8 in PPSSPP after 30 seconds of gameplay It used to drop to 6fps and now it can sustain over 20fps after reaching 71C on a single A57 core. I only saw a maximum battery temperature of 40C and the device wasn't noticeably warmer than it was with the default thermal settings.

Well yes. Except that's the little cluster and they don't get that hot normally. It's the big cluster that needs to be modified. I also tuned my display thermals so the screen wouldn't get so dim when the phone gets warm. Here you can look over my configuration if you want.

your settings somehow "unlocked" my phones cpu. lol in geekbench I found an increase of performance of 200 points in multicore from 4020 I had before maximum , now nearly 4300 .It is impressive. also if I run 6-7 geekbench in a row there is a decrease everytime ex 4200 4050 3900 3600..... but temperature stays 45 degree.
I will test them more later.

Thanks for sharing your results. That's the highest multi core score I've seen on our phones. I never gotten that high of a multi core score. Glad to help. My configuration also tweaked the battery thermal settings so now you should see faster charge times as well. The default charge rates had really conservative thermal settings and the high speed charge would drop after a while but now it will 2.2 to 2.4 amp charge through the whole charge.

Yes indeed i saw a difference in chargin thanks for your effort in the configuration. I am not very fond of benchmarks but i run some in my devices after magor changes (firmware....). This device should have been speedier because of the full hd snapdragon 810 combination. I wonder if we delete the thermal config is the device gonna be speedier? I am waiting for 5.1.1 hoping for smoother rom. Lets hope soneone unlocks the bootloader!!!! I took my precautions disabling MLT lol

When you apply the settings you need to give time to the phone to 'absorve' them.
Run a couple of benchmarks, test a 4k video, reboot the phone 3-4 times, close it also.
I havent noticed higher tdmperature of 45 celsius.

I'm not sure what would happen if you just deleted the file. Maybe it'll revert to some default, or perhaps it won't thermal throttle at all which would result in auto shut off when it overheats. Probably not worth risking it without a custom recovery in case it doesn't boot.
I have notice that my phone is way quicker now. It was fast before but now it's a beast when I push it hard. Also things like PPSSPP emulator was useless with the default thermal throttling now it can beat my Tegra note 7 with 4 A15 cores at 2.1ghz at it.
Was there a problem with your settings? I noticed your settings you had shared on dropbox are no longer available.

The folder was deleted for some odd reason. I was able to restore it so the link should work now. Let me know how it works out for you.
A few questions about these settings.
-At the top where you have SS-Little_Cluster_management and SS-Big_Cluster_management is the set point the shutdown temp for the entire cluster?
-I think this one is self explanatory by the action listed but towards the middle where CPUx_MONITOR for each core is, is the threshold the temperature at which the entire phone shuts down?
-I'm not sure I am noticing the difference between SS-CPUx and CPU_HOTPLUG_MONITOR. Could you explain these?

I don't want to assume I know everything about this. Everything I know about the thermal configuration file I learned from seeing others modify the LG G3 thermal config file. I also learned some by experimenting with my G Flex 2.
In my understanding SS-Little_Cluster_management and SS-Big_Cluster_management is the temperature at which the Cluster will thermal throttle when all cores in the cluster are being used at once. From what I've seen anything with "action_type 10000" means thermal throttle. The closest thing I can think off that works like that is how Intel I5 and I7 will limit turbo speed when more than one core is being used. Except in our case this is to prevent higher speeds when it reaches a certain temperature. So lets say your phone is running some heavy multithreaded app now it's going to follow the rules set in Cluster_management. The default Big Cluster temperature is set to start slowing things down when temperature reaches 48C and to not go back to full speed until the temperature drops down to 38C. One thing I find interesting is that at about 48C cluster temperatures was about where the Big cores would drop to a max of 1.5 ghz. So I'm just guessing that this setting may play a big part on the big cores max speed.
[CPUx_MONITOR] seems to shutdown the phone when the core reaches a certain temperature threshold of 120 C and I assume will not allow it to turn back on until it drops below 115C.
[SS-CPUx] on a big core seems to slow the specific core down when it reaches a temperature threshold of 85C and to not allow it to go to full speed until it drops below 55C. However this rule can be overwritten by [CPUx_HOTPLUG_MONITOR] which can shut down a core even if it hasn't reached it's maximum temperature threshold.
[CPUx_HOTPLUG_MONITOR] just tells the specific core to turn off once it reaches the temperature threshold specified. On the default configuration core 4 and 7 are set to turn off when their temperature goes above 50C. After that core 5 turns off at 58C and even core 6 turns off at 61C. At which point only the small cores will remain on.
I hope that helps somewhat.

Battery and Thermals

Hi guys,
I noticed that battery voltages seem quite high on my device: at the moment, about 4,373mV according to accubattery and cpu-z.
I am getting this reading at 96% charge and without any charger connected.
Which battery voltage and temperature do you get on yours? Post some screenshots Many thanks!
i would be more concerned about ur SOC temps being at 96 deg C than ur battery voltage honestly..

Exactly, noticed that and was wondering if it's actually true or if it's cpu-z giving a bad reading. Comparatively, what's the SOC temperature you typically get?

Interestingly, CPU monitor gives me a reading of 41°C on the CPU. AIDA gives 85°C on the SOC.
Can someone pls post their results here? I'm wondering if this a defective unit.
For me it's the same , way higher on Aida while on CPU monitor are always on 37-38 c even when the phone feels hotter

It could for some reason be displaying fahrenheit instead of clesius 96ºF is about 35ºC

Thanks, mate. Can you also pls post here some screen from your readings on AIDA, CPU monitor and possibly Accubattery?
What sort of battery screen-on-times are you getting?

Guys, actually I found the answer for this in the meanwhile.
A bug makes SoC temperature to be listed with the same number as the battery percentage of the phone in a given moment.
For instance, on the attached screenshots I'm including now, you'll see that AIDA lists 85ºC on SoC when I'm interestingly at 85% battery. The same for CPU-Z, listing 83ºC there, when I'm at 83% battery.
A funny one, right?

I had the same bug as you but i didn't notice
I got around 6 hours of SoT using bluetooth and 120hz and a little bit of 4g, gps from 100 to 20%, but I can't give accurate sot times since i've been charging it partially these last few days and also i cant post photos cause i'm new
And battery life? SOT please
So I just received the phone with 65% battery... Do I need to charge it first time for 8 hours?
Relax, honestly I would just use it till 20 ish and give it a good overnight charge.
