Hi, im new to this phone (i9505) and ive noticed how easy it is for the gpu (adreno 320) to throttle down to 200mhz from 450mhz is just 55 degree celsius.
I have an xperia z that has almost the same specs yet it throttles at like 70 degree celsius.
Is this normal or does my galaxy s4 has a problem or something? Already tried both stock 5.0.1 and lineage 14.1, same result. Also updated bootloader just in case it would yield a difference but it didnt.

Hi guys i got my nexus 4 a few months back and i am very happy with it.
I rooted it and i'm running Cyanogenmod 10.1 with Franco kernel r136. My current settings are
Minimum CPU frequency- 384Mhz
Maximum CPU frequency- 1350Mhz (i underclocked it)
My CPU Voltage settings are (followed this thread
http://forum.xda-developers.com/showthread.php?t=2155495
384 - 700 (-150)
486 - 700 (-175)
594 - 720 (-180)
702 - 740 (-185)
1026 - 825 (-200)
1188 - 875 (-225)
1350 - 940 (-185)
1512 - 1000 (-150)
Just checked Device Monitor in franco kernel updater app and clicked it. It is showing CPU temperature is 42 Degrees(106 F). I am a bit worried with this temperature. Is it normal ?? I have no apps running in the background. When i watch 1080p movies it raises upto 48 Degrees.
Any way to reduce the temperature ??
Thank you
Thats normal for a quad core device like our Nexus 4.
And to be honest, it is actually quite low.
Think of it like this. Your body is on average 37 °C. The temperature of your cpu is only 5 degrees hotter than your body.
The cpu can handle way higher temperatures like that, eg. when playing a game.
And when your cpu gets too hot, the phone will shut itself off, so dont worry about it.
lol, that a few degrees warmer than your body temp.. 98.6F
Thanks for the reply. I live in india and we have 44 degrees temperature. Does this effect my phone ???

yes. your phone temperature will also depend on the ambient temperature around it, and itll affect how fast itll cool down too. if the temp around it is 44C, youll need to expect higher phone temps then someone living in a cooler environment.
I just restored my phone from the red blinking led issue, but my cpu temperature is nou 60C idle mode, i think thats a bit much..
Anybody experienced something similar?
I was just curious to what is the max temp of the CPU. because my note 2 will idle near 32*C. Whereas this phone idles 40*C. Battery also isles higher too.

100C is the safety temp. itll automatically shut down to cool off at 100C.
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?
Best regards
dingolino
Gesendet von meinem SM-N910F mit Tapatalk
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.
I had this issue that on some games the fps start to be dragged down after 15, 20 min. I've instaled new custom kernel for thermal throttle due to cpu heating, but seems to be related to gpu, as the cpu stays constant at about the same speed. I have seen a fix for s4 on the web: to change a value in this file min_pwrlevel, though there is not on this os. If Anyone has an fix for gpu thermal please give advice. Cheers.

Hi. Is your S5 overheating?
Room temperature: 17,5 Celsius
Device: Samsung G900F
Rom: Samsung Revolution ROM 5.3
Thermal monitor app: CPU-Z
Idle: 32-42C
Downloading apps from play market: 41-50C
3D Gaming (game: Torque Burnout): 82-91C
Is it norm temp???
Please share your results!
Nope,
Idle is 24 degrees C
Charging Idle is ~30 degrees C
Gaming is about 35-40 degrees C
Gaming while charging is about 45-50 degrees C
I have the KT kernel and use a light case, not too restrictive.
I have enabled QC and have a slight OC.
In short, no.
Try using Coolify.
That's normal

I'm having the same problem. That is not normal. I just saw 89 celsius, haven't playing any games or installing apps. How can I fix it?
by enabling "FORCE GPU RENDERING" in developer options
this will decrease load on cpu
I play GTA SA in high quality and in a few minutes it is slow, Temple Run 2 loses many FPS, GodFire falls from 60FPS to 30FPS or less, Asphalt 8 begins to have low FPS.
I analyzed the performance of the GPU and CPU:
The phone heats up, reaches an average temperature of 70 ° C (158º F) ~ 80 ° C (176º F) , gives peaks up to 90 ° C (194º F) on hot days.
The GPU performance drops a lot.
The GPU performance falls gradually from 578 MHz to 190.73 MHz and no longer increases until the temperature cools.
I live in Brazil and in recent days made a lot of heat - 32 ° C (89,6º F), is now doing 15 ° C (59º F) and the GPU performance drops to 305 MHz in less than 10 minutes.
I have the S5 makes a week! I received from the Samsung because of problems with the S5 Mini GPS.
This is normal? Or my S5 has problems?
Thanks in advance!
It is G900M - SnapDragon Version
It has no root
Version 5.0 Lolipop

Which version of the phone u have? G900f?
And what version of android are u running?
And are u rooted?
It will throttle if it overheats, playing GPU/CPU intensive games on a hot day is a good combination to overheat the phone
Find somewhere cool and try playing them again, see if it still throttles

Today is 18ºC (64,4ºF) and it heats up to 85ºC (176ºF) according to the CPU-Z and GPU reached drop to 190MHz, as well as on hot days.
The average temperature is 45 ° C (113ºF) today without using it. It is normal on hot days is higher than 50 ° C (122ºF).
The processor did not exceed 70ºC (158ºF)
I don't know how high it is acceptable. I mean, lose the GPU performance in a few minutes.

That's pretty high, have you done a reflash/factory reset? Some process must be making it run like that.

I've tried, I have almost nothing installed. If I do not use the S5 the processor is almost stopped.
Also this occurred in 3 Lolipop updates I have received beyond the first.
The first time I turn it on and I set it up, he came to be very hot, downloaded CPU-Z and marked up to over 80 ° C. (The day was hot)
(Sorry for my english)
Can someone help me? Share the experience?
thats hot,i live in malaysia where the temp as same as there and now the weather became more hotter than usual in here , but my s5 g900f just acting like normal,no fps drops , even when im playing with heavy games together with vpn apps.
maybe your phone hardware got somehing wrong wih it.
Thanks for all the answers. I took my device in technical assistance for analysis and see what happens ...
If anyone else has expriencia, please share.
