note 8 cpu temp 71 f

my note 8 get very hot when i play modern combat 4 the temp about 71 degree (measured by system tuner ) and the battery temperture about 37 or more and the left side of the screen becomes very hot and the battery drain quickly is this will harm my device sorry for my bad english ??

This might be a question better answered by Samsung (unless it is a carrier model). Many questions though....
Does it get too hot to hold? Are you charging it while playing? Is your tablet oc/ov? What is the ambient temperature where playing?
Here is a previous thread with this same topic: http://forum.xda-developers.com/showthread.php?t=2251830
Might scroll through the posts and maybe even post there about it as well. Sorry, can't help anymore than this.

yes some times - never charging while using it - iam running the stock rom witout any modification or oc - the cpu temperture while playing about 71 degreer

71 degreescelcius or Fahrenheit? If Fahrenheit that's good...

But its not a problem. Your device will power down or turn down CPUs when you reach a certain temperature threshold. At least I know my phone does. I've never seen temperatures like that on any of my devices. The most I've ever seen even when over clocked to 2.1 GHz is in the 50s. Even then I'm not worried about it damage isn't done until the high 80s 90s. But how are you getting these temps. Are you outside in 90 degree heat gaming? I even have my GPU way over clocked and I never seen 70.

in modern combat 4 it reaches 70 c and the left side of the screen become very hot

Yeah, only problem I had with this device and my Note 2. (same processor). These bad boys heat up. Especially if you do alot of flashing of roms.

Yea I ran my note 2 really hot playing dead trigger last night and overclocked 1.92 ghz plus 733 mhz gpu overclock but I still dont have heat readings of more than 56 celcius. And I have an app that monitors cpu temperature while im playing so I can see it in real time. Maybe your device is having a problem. Oh do you have a real thick case? That can cause heat buildup. If I leave , y case on my note 2 while playing a game it causes less heat dissipation and runs almost 10 degrees warmer. You might wanna consider that

Why will undervolting harm your CPU or battery? I can see stability issues with undervolting and have experienced them while experimenting with the settings. I cant see how it would harm the hardware though. As someone said above. The device should shut down if the processor gets too hot to protect itself. Also, undervolting should reduce the temperature.
The built in powersaving option in touchwiz will underclock your cpu to 1.1GHz. you can set it back to your standard setting with a push of a single button the menu.
I overclock and undervolt and have no worries about damage. I have had issues with my tablet turning itself off sometimes, but it has only happened on particularly hot days. I reduced my OC from 1.8 to 1.7Ghz. And i reduced my undervolt from -75 to -50 vs stock as I was having the occasional crash.
Are the CPU and GPU on the same processor or located in the same area of the tablet? I hear alot on hear about the CPU temp making the device extremely warm but wondered how the GPU acted. If you underclock the CPU, does this put more load on to the GPU when playing games or will the GPU load be the same regardless.

i cant undervolted because the CivZ-Sb kernel is not working with 4.2.2

Big Cores are always stopped!

Hey Guys,
i have a problem with my Nexus 5X since weeks and now I think I have founded the problem. On daily usage, in games or in Benchmarks: the two big Cores are always stopped. Bit I don't know why. I have tested it with some Games, Geekbench and CPU-Z. Can anyone help me?
Thanks

The thermal throttle stops the big cores when they reach a certain temperature. It's "normal" behavior on this cpu.

But they are stopped all time. When I Power on the device and start a big game, when I wake up the device after a while and play a big game... ever! Temperatures are round about 55°C

If you're on one of the Android N Dev Previews then it is probably the well known bug that shuts the big cores off. If you're on Marshmallow then it is most likely thermal throttling. I think the big cores turn off at about 45C.

Okay. But why does my device heat up so fast? I have read a few Tests and the Processor never gets hotter then 42°C.

It's your use mostlikely, e.g. camera (, cpu intensive games, benchmarks etc) takes all the cpu power possible, that'll heat up your device into range of thermal throttling in no time, while one can browser normal websides for hours without any signifcant heat building up.
---
I think it's a general misunderstanding of how a big.little cluster cpu works. Those aren't 6 equal cores, the big ones are (most of the time) just there for short term boosts and otherwise drag down performance overall, especially when the cpu heats up. I can see a much higher use of the big cores e.g. when loading websides compared to gaming, where it comes down to how the game can run on the remaining cores (little ones) after a few minutes.

But the Cores shouldn't heat up after a few seconds, should they? And they are simply alsways off.
I have tested it with the Geekbench 3, Smash Hit and the Camera App. The results like the temperature and the clock Speed came from CPU-Z.
My Standard result of the Geekbench is 650 and 2500 points. The two big Cores are stopped and the temperature is round about 50°C
The Standard witch I have found in the Internet was 1300 and 3600 points. The temperature shoult be round about 42°C-44°C

Does the OnePlus 3 get extremely hot to the touch?

Everywhere I looked they said that the OnePlus 3 has the least thermal throttling and best sustained performance of any phone out there. But nobody discussed why exactly it did not throttle while other phones did. Everyone simply said "Oh they must have very good thermal management or something". Then I saw a video comparing the temperatures of the ZTE axon 7 and the OnePlus 3 (google "Zte axon 7 vs OnePlus 3 antutu thermal throttling"), it turns out the reason the OnePlus 3 doesn't throttle isn't some magical thermal dissipation and management, it's solely because they raised the temperature at which the phone would throttle to beyond comfortable zones. In the video with just a few iterations of Antutu CPU test, the OnePlus 3 metal skin's temperature reached a scorching 47 degrees Celcius. Google shows that holding anything metal at 50 degrees Celcius for more than a brief moment can cause tissue damage (1st degree burns). And this phone was just shy of that temperature during Antutu's benchmarks when only the CPU was running, so can you imagine what temperatures it would reach when you're playing a highly graphical game where both CPU and GPU are being taxed at the same time? Why does nobody talk about this?

Thank you for your useless opinion friend.

The only game i play on the one plus it's hearthstone but I don't notice an high temperature during session ... I think a benchmark it's one of the most stressful things you can do with your smartphone...

No actually Hearthstone is not a demanding game at all, not even remotely. In fact an iphone 4 could run it without busting a sweat. And many games can actually be more stressful than a benchmark because you would be running both CPU and GPU at the same time and would likely be running the GPU at 100%. Most GPU benchmarks run the GPU at 100% too but without using the CPU at the same time.

A non issue imo

I can't figure out why the hell that idiot in the video used real racing as a benchmark. Do these people even know what a GPU or CPU is?
Anyway, that video is not reliable, especially since the OnePlus 3 uses a 1080p display and has to push far less pixels than those other phones, that game does not tax the phone's hardware in any way shape or form.

The CPU starts throttling at 75°C like pretty much any other phone out there... This thing just dissipates heat better than any other Android phone out there which is why the chassis heats up a bit more. Don't worry it doesn't get that hot at all

The fact that there's a lot of us out here using the phone, but as far as I've seen zero reports of people getting burnt by hot phones, in. Y experience it stays way cooler to the touch than either of my last two phones (Xperia z2 and Samsung s3).

CPU Thottling?

Does the Samsung Galaxy Note10+ (Snapdragon) throttle the CPU to save battery life or manage heat? If so, is there some way to modify that?

Of course there would be a way of doing it, but first root must be achieved

i believe so i keep it on high performance mode at all times

I've only seen this happen if you have either of the power saving moves enabled.

I ran a test with the device set to high performance mode, and there is definitely some modest throttling after the 2 minute mark. Root can't come soon enough.

So you want it to overheat instead of slow down? Damn thing says 174 degrees.

Can someone, who has the Exynos version, do the CPU Throttling Test and share the picture, please?

The only rootless setting you can set for it is the moderate power save that fix it to 70%
You need root otherwise.

Every CPU have Throttling. This is about temp. increasing. Have one test in GSMARENA.COM
Flagships vs Gaming phones. After 1 hour hard gaming casual flagships decreasing CPU power on 60, 70 % to prevent overheating. In Gamer phones like ROG or Black Shark decreasing is only around 90%. This is because they have active cooling systems.

I agree. But not only gaming devices. For example, Sony Xperia XZ Premium doesn't throttle that much.
I just wanted to see if there is a difference in Throttle on Exynos and Snapdragon.
If someone could do a CPU Throttling Test on Exynos, I would be very happy!

Exynos is horrendous. Just look at gips. Im starting to believe more and more there's something wrong with my device.

Question What’s the best brand for overclocking sd 865 to 950 MHz?

I recently discovered that the sd 865 can be oc to 950 MHz and beat the sd888 while using less power and producing less heat ! So I want to know which brand is best in terms of overclocking and support for 120 fps in games even if the phone doesn’t natively support 120 fps , in which brand you can unlock it after rooting and oc the sd865 to 950 MHz and has an app to disable the thermal threshold ? Thanks in advance

OCing increases power usage and with that comes increased heat. CPU cycles aren't free...

I know thats why I’m planning on cooling it with a custom solution but I what I meant is that the sd865 overclocked still uses less power than 888 and produces less heat

The 888 may be unbalanced heavily favoring gaming at the cost of not be able to do other activities efficiently. Could be a 5nm flop. Not every chipset is a winner
My 7mm 855 does very well, the 865 is a solid chipset.

Oneplus 8 series , Poco f2 Pro Mi 10 series Mi 10T and Red Magic 5G /5S
865 doesn't overheat and uses still less power consumption than 888 even with OC
