Hi all, my S4 i9505 has been getting battery temp of 36degree Celsius and GPU temps hovering around 44-52 when doing nothing with some background apps (reaches 64 when playing Clash of Clans), 42-48 when in standby. Is this normal? The phone is rooted and has ktoonsez' kernal. I don't think I noticed these high temps before I tried to overclock the S4 to the max (was just playing around to see if GTA VC will receive any performance increase) which resulted in the phone rebooting twice while vibrating a little. Since then, I reverted the overclock by going into recovery mode and then reboot and only now I noticed this temps., also, I had to uninstall GTA VC as all it did after the reboots was freezing at a white screen after the intro. Thurs far, I have not noticed any performance issues. I am currently using Danvdh's customized Google Edition 4.4.4 ROM.
And if it matters, my phone scored an average of 22k in AnTuTu at 54degrees. 26k, albeit below the average S4 when I left it in standby for the whole night.
Hi,
I know that thermothrotteling is a feature to protect the cpu against damage. But what I notice that the temperature on my Note 910F is raising quire fast and that I am running into performance issue quite easily. Just playing arround the internet , watching something at youtube is bringing the device into the throtteling mode and than everthing is in slow motion (no hardcore games are neccessary). On my Note 3 I was never aware about such a situation.
Im using the Echoe rom 1.1 with the Ecoe kernel 3.5 (and fairly conservative power saving settings), but it is not kernel related because on stock it is the same.
Anybody facing a simelar situation?
Best regards,

Thats not normal :/ i guess sd being 28nm and clocked at 2.7ghz does generate some heat
Your not alone. That is the very reason why I rooted my phone yesterday. The Samsung DVFS is very aggressive on my note 4 with 4.4 kittkatt.
Iv noticed in benchmarks once my phone heats up a little it drops the GPU and CPU down to about half speed and im only getting half the score and in gaming after a few minutes I would start to notice a little lag and my cpu speed would be staying at 1297. It slowly drops down to that then stays around there.
I disabled the Samsung DVFS and use setcpu aswell to keep it at the full speed while gaming and it works great now and the temps are hardly any different.
Many thanks for the feedback.
I have switched off Touch boost und set Max cpu to 1.9GHz
Will see how it works.
Best regards

It is quite annoying have such a fast phone but it downclocks both the cpu and gpu after a few mins of gaming.
A good test is GTA vice city with the settings cranked up.
With DVFS enabled once it hits about 56 degrees it starts to throttle and downclocks the gpu and cpu to about half and the game becomes a laggy mess.
With DVFS disabled its as smooth as butter but the temp goes up to about 70 degrees. Whats the max safe temp for this phone?

I do not know the safe setting.
I am using the echoe kernel and this kernel offers the “intellithermal“ feature from faux. You can set the temperatures when frequency throttling should start as well as kernel throttling. They give in the faux app also some recommendations.
Maybe you give out a try.
But I am disappointed because the throttling is affecting “normal“ life not only hard core gaming and this is for me somewhat a design fault.
At least on my Note 4 F
I never had this on my previous devices that I cannot watch a movie which is stored at my sd card. I have a number of tutorial and maintenance videos which are handy to watch on the device.

I can confirm this on the N910W8. As soon as the device heats up the frame rates drop dramatically. I also don't game. Just day to day usage. It's strange that some fairly simple tasks can heat things up so much.
I removed my ScanDisk 64GB Class 10 SD card which seemed to improve the heat problem.
Also, when its cool it smokes through GeekBench 3. After it heats up it runs slower then a Galaxy S3.
Just you my friend, I don't have that problem

Donkon....can you let me know what your idle phone cpu temp is? you can use the CpuTemp app and just let me know what it idles at on your homescreen and what it heats up to in a demanding game. Just make sure its the CPU temp and not the battery. thanks
It would be good to compare.
Also I was just doing some tests and these are my results.. im curious to know if these are normal temps.
My phone idles at around 34-38 degrees c.
With DVFS enabled it never goes above around 56 degrees as that's when it starts throttling down.
Iv never had any slowdowns in youtube or videos or anything like that. Its only gaming really and benchmarks where it starts to throttle once it heats up and in a game like gta it starts to lag abit once it throttles as it takes the gpu and cpu down to about half speed.
With DVFS disabled im able to run the full 2647 cpu speed when gaming and its as smooth as butter. My temp in riptide goes up to 58 degrees. In GTA vice city it goes up to around 70 degrees and in the unreal benchmark demo it goes up to about 74/75 degrees. Do these sound like normal temps when your running the full speed of the cpu?
Yeah, it is ok.
The Exynos start throttling at 80°C.

Which kernel are you using and what means “DVFS“?
Which app are you using for the kernel settings?

Im using the stock Kernel. Iv only rooted. I haven't installed a custom rom or Kernel yet.
the DVFS is samsungs own voltage and frequency control program. Its what causes the aggressive thermal throttling in kittkatt 4.4. Its been there for along time but in 4.4 its pretty much too aggressive.
When you disable it the phone wont throttle back the GPU and CPU and a silly 56 degrees so it wont start to lag in games after a few minutes.
If anyone has GTA vice city or the epic citadel unreal demo can they run it and tell me what there CPU temp goes up to in those.. I just want to make sure mines normal as it gets very hot. With DVFS it should go up to about 55-60 and without it will be around 70.
Does anyone have freezes followed by restarts when disabling DVFS for just some apps (using blacklist)? I have this problem and disabling DVFS for the whole system really annoys me (opening app speed is slowed down + power saving mode requires a restart). I'm using the exynos C version.
Hi guys,
I am experiencing some strange "problems" ( or not ) with my N910C.
When I am using the auto brightness feature I believe my CPU and/or GPU is not performing as it should. For example, running AnTuTu with auto brigantines - 41-42k points, running it without auto brightness 51-52k points....
Also I believe the phone is lowering GPU and/or CPU performance very often due to temperature increase. My phone is not really hot but its not cold either.
I´ve tried games like Beach Buggy Racing and Modern Combat 5 and they do not run as smoothly as they should ( I think )
Is there any way to stop the CPU and GPU for lowering their frequencies due to temperature as I think the temperature is not high at all.
I am not using any power saver or anything else. Just pure stock Lollipop.
I had the same problem with KitKat. My best gaming and benchmark time is when my phone has been sleeping for a while.
Can someone confirm similar issues? For example if you run Antutu 3 times in a row what results are you getting? First around 50k, then the following around 41-42k
Thanks in advance.
I have been doing some heavy gaming on my G5 while monitoring the temps, and to my utter amazement G5 never goes beyond 40C mark even after an hour of continuous gaming. Because of that it never throttles down and stays at max cores almost the whole time. Now, coming from G3 this is a HUGE improvement where normal temps would go beyond 80C and throttling would make gaming virtually unplayable (even after root and thermal tweaks)
Sample temps comparison after at least 30min of continuous gaming (room temp around 23C)
Lara Croft GO - Max settings
G3= 80C+ lag and throttling
G5=36C+ smooth
Xenowerk - Max settings
G3= 80C+ lag and throttling
G5=35C+ smooth
GTA San Andreas = Max settings
G3= UNPLAYABLE
G5=39C+ smooth (yes I cannot believe it finally runs like butter )
Dawn of Titans = Max settings
G3= 80C+ lag and throttling
G5=41C+ smooth
Real Racing 3 = Max Settings
G3= 75C+ smooth
G5=31C Lag
There you have it, overall a whole 45+ difference in temps while gaming !!! Not only do games run buttery smooth, the phone stay cool as a cucumber.
The only exception here is Real Racing 3, which I think needs to be patched to work properly on newer hardware (even S7 SD820 has similar performance issues)
This goes to show that Qualcomm have done a miracle with SD820 and kudos to LG as well for proper hardware implementation.
Let me know what you guys think and if you want me to do more comparisons like this
i hereby confirm the temps and add temple run 2 (both maps, runs like butter in the mines), asphalt 8 aswell as modern combat 4 and 5 to the list of low temp max settings games.
even antutu keeps it cool
I can use Autoguard dashcam software with GPS enabled, waze in the background, and charge my phone and it's only slightly warm.
Hi All,
I mainly play COC and Clash Royale and notice the phone overheat up to 70-80 Celsius. Sometimes its so hot, you feel your face burn when answer phone calls. Any ideas which ROM doesn't heat up this much? or its normal for Note 4 to be this hot during games?
Device: N910C
Current rom: Dr. Ketan M6
Kernel: Emotion R26

It's normal issue with all the note 4 because of 1440p 2k qhd screen.
You can try any note 7 rom and turn down screen resolution to 1080p orr 720p and use custom kernel turn down cpu max frequency from 2.7ghz to 1.9ghz and minimum frequency to 300mhz
This will probably keep your phone cool when playing games.
you also have to turn down graphics from max to medium or low in game options you are playing.

I also play Clash Royale, but I have to put the governor in Performance because if not the game goes with stuttering. With Gametuner I lower the resolution to 30% but the cell phone also heats up a lot. I have not tried in the stock rom to compare. I use ManuPro AstraRom
