So I disabled the DVFS feature which I heard was some kind of thermal control but now the phone is unbelievably hot after intensive gaming session. For example I played xcom for 30 minutes and the phone felt like frying and the battery went down from 86% to 48%. I didn't have any cpu monitor so I don't know what temperature it was on, but it felt very hot. Is this safe? I personally think it isn't and I will probably turn DVFS back on.
I have a n9005 device, running xnote v15 and lean kernel 2.5.1 with default settings.
From what I gathered, DVFS was Samsung's "cheat" to enable awesome scores in Antutu and other apps that measured how well the CPU, etc worked... Disabling DVFS should in actuality leave it cooler as the CPU's/other aren't being artificially throttled up to maximum...
Correct me if I'm wrong...

Isn't the dvfs stock kernel related?

No its TouchWiz system based. You can set it in Wanam Xposed.
It may sound like it's related with the kernel, but the kernel does not see what is being run on the device (especially only benchmarking tools) and then ramps up the device to perform better than expected.

According to the System Tuner app, my CPU went up to 75 degrees Celsius while I was playing a track on Google Earth. I was running Earth for only a few minutes before it reached 75. I'm not sure if that's the peak yet...maybe it can go even higher.
I've seen several other threads about heat, but most people talk about 50s and 60s. Anyone reach 75C? The front and back of the phone, the top around the camera, were both very hot. It was almost uncomfortable to touch.
Again, I'm talking about 75 Celsius, not Fahrenheit. And I'm referring to CPU temperature according to System Tuner app, not battery temp. Anyone reach this?
picture plz.
the reason is bc someone did a stress test on the N4 and found that the device shuts down at ~57-59C (correct me if im wrong) to prevent damage to the hardware.
Edit: found the link http://www.youtube.com/watch?feature=player_embedded&v=koLJ4BU9tgc
75ºC on a quad core?
I thought it was supposed to be more efficient than a dual core... 167ºF just seems like it's way hotter than any electronic device should ever be.

My first gaming laptop was an ASUS Republic of Game first generation. They did a horrible job cooling the machine. During the 2 months before the machine failed, the GPU would reaches 110 - 140 C if I played games (then, of course, the machine turned the GPU off and still ran as everything else was still about 70-80 C)
When the machine did fail, I opened it up, and found 2 fried thermal unit, a fried GPU and a nearly fried HDD) Amazingly, the machine stills runs, as long as I don't load GPU driver
Well, that's the story. Back to OP, as you see, if the temp is too high, you device can be literally fried. So if you turn off the thermal throttle, please enable it back on and do you best to keep your device cool
I tried to replicate just now and could only go up to 63c. I don't want to keep trying based on the comments here so far. If it happens again I'll be sure to get a screen shot and be aware of what's running.
Where would the thermal throttle toggle exist, if I have the capability at all? I'm running faux123 kernel and use trickster mod and trinity kernel tools for tweaking. I don't see anything about throttle control.
On a similar note, faux123 seems to default to 1ghz minimum cpu frequency. Does that seem right? I've flashed lots of kernels before on previous phones and they always default to the lowest value. When I force the setting down to 384mhz, it automatically changes back to 1024mhz the next time I go in my tool apps. Does this seem normal?

I haven't seen a Nexus 4 kernel that has thermal throttle toggle, or have it disabled yet. I am just checking if you're running one that I am not aware of

Minimum cpu frequency enforced by kernel is normal. I am not certain if faux123 default to 1 ghz min, but if it's the case, it seems weird for me too. Definitely not good for the battery. If there's no other CPU control apps, I recommend double check the settings, then find an update for faux123, or use trinity kernel
I just flashed a new kernel and my minimum cpu now seems more normal. I hopefully that alleviates the crazy temperatures too.
I'll try to test again tomorrow to see if my temps still go bonkers. It's time to sleep now. Thanks for the help, everyone.
Not sure why but ever since I flashed release 7 of the faux kernel my phone just seemed to get really warm, now I don't know if i just never noticed it but I'm running Motley kernel now and my phone just gets warm at the top when installing apps. I'm not sure if I never noticed it and I'm starting too or if I have a problem, HELP? Thanks.
That's completely normal. When installing asps the CPU is being used. Also, the CPU governor being used and uv'ing affect the temperature. Also, the CPU is located at the top I'm guessing.

Hey, I'm wondering too ! Since i flashed the latest faux kernel (release 007m) , my phone seems to be warmer than usual. According to the system tuner widget the phone runs around 45°C after a few minutes of use and sometimes reaches almost 60°C while i do nothing special on my phone (a little browsing, sms). Despite the fact that I've downclocked the cpu to 1.35ghz, put the governor on intellidemand, disable mpdecision, UV 75 mV and running at the stock gpu clock. I don't know if this is normal but this seems to be a lot. What's gonna happen if I play games or some more intensive apps?
Hi guys,
I have the 855 version of this phone, and I have noticed that, even if Antutu scores are spot on (44k), in games such as GT racing 2 or similar I get a lot of lag.
Now, everyone will think "there are 1000 threads about lag, stick to those". Unfortunately, tricks such as getting rid of the thermal protection are really not good options, as the phone temperature will start to skyrocket.
There's a much easier and safer solution: root the phone and change the governor from interactive to conservative.
With interactive gov and CPU temp open in the background, I have noticed the CPU frequency bounces continuously up and down between 300mhz and 2400, even if the CPU temp is only 55c or so. This is causing the lag! Interactive governor is severely bugged, and this happens with any rom (I have tried both the stock 20h and the ChupaChups 4.2) and kernel (non AOSP at least).
Then, I switched to conservative, launched the game again, and guess what....now the frequency is nicely stable at 2457mhz throughout the entire gameplay and lag is gone completely. Temperatures? Totally fine: max 60c while playing and usually between 35 and 40 while whatsapping.
I literally tried everything to get rid of this damn lag, and the only thing that worked before this solution was to use a different kernel (chupa chups 2.1) and changing the governor...but I was getting crazy high temperatures, that sometimes touched 80c, and this was with a very heavy undervolt too! So I recommend to use the stock kernel, because it's the only one - for me at least - that grants good performances (and by that I mean no lag in games whatsoever and constant 2450mhz while playing) with good temperatures.
Any other option, including undervolting and trying different kernels didn't work for me, because either the CPU frequency kept shifting up and down every second causing lag, or - when I managed to keep it stable using different kernels and undervolting - the CPU temperature while playing got way too high (70c+, touching 80c sometimes).
To sum it up
1) Stick to stock rom and stock kernel (because of temperature issues)
2) Root
3) Change governor from interactive to conservative with Trickstermod (busybox required)
4) Enjoy smooth gaming experience and very good temperatures, with no significant throttle whatsoever!
Hope this helps!
as far as i know, conservative puts the cpu speed into the lowest possible, thus i thought won't be good for gaming performance.
nevertheless, i'd try for a few days and see if there's any noticeable difference.
thanks for sharing the knowledge, OP!

Theoretically you are right. But...interactive is bugged. Ondemand doesn't work (it will make your phone freeze) and performance will drain too much battery. So we are pretty much left with conservative.
Give it a try, and when you do, make sure you have CPU temp open to monitor both temperature and cpu frequency!
Let me know
Thank you! It really did the trick, gaming became MUCH better.
I tried RR3 - it became a lot better. On interactive it lags even in menu, on conservative it's rendering at 23-30 fps with slight not-game-breaking lags.
Battery
And about the battery? Will drain more in conservative than interactive? And will speed up the phone in all app or only in heavy games, when cpu is more active?

I wouldn't worry about battery life..
It seems that this working generally, phone is much snappier and smooth for me than on interactive.
Yeah...the reason is that LG did an awful job with the interactive governor, and what's even worse is that it's actually using it as the default one.
Pretty incredible how bugged this is.
Yes but I think it's possible to make script in init.d folder to run conservative on boot as default. Maybe someone make one.
I Will try this ☺only for curiosity! I need busybox installed too or trickstermod only?
I've been doing the same thing for a long time now. I use SetCPU to automatically switch to the performance governor whenever the screen is on, and interactive whenever the screen is off.
You may also want to consider disabling mpdecision and thermald also. One of the two (probably mpdecision) will regularly change the governor back to interactive if you don't.

I'm running Rin kernel with Lionheart governor on stock kit kat on a D850. It's ages better than interactive. I have plenty of governors to choose from, I'll slowly try them all.

That works to get rid of the lag...but my phone was reaching easily 80c.
Now, with everything stock, the frequency stays nicely at 2457mhz with no throttle at all and the in-game temperature only maxes out at 63/64c.
Thanks for sharing this brother...just switched to conservative in trickster and I'll see how it goes.
I'm on crash Rom stock kernel with thermal mod activated...
Don't have any temperature issues till now expert while playing heavy games for some time.
Thanks again
Are the settings in trickstermod applied as you change the setting ? Or do you need to apply them manually ?
Also, do they apply on boot ?
I will try that, thx for the info.
Now how i can put it to change on boot?

On the latest trickster version you hit the upper right settings icon and the first four option that appear are under the set on boot part.check the kernel setting to be set on boot and you are done.
Of course after changing the governor that is...

I am currently running the PureNexus rom with ElementalX kernel while also underclocking the CPU but I still seem to run into throttling issues. What are you guys doing to help keep your 810 cool enough not to throttle but still maintaining buttery smooth performance?
Thanks
Not doing anything on mine. I haven't gone and focused on benchmarks or anything that has caused me to notice throttling on my device. Seems to work quite well and performance always seems buttery smooth while I'm using it.

Nothing, I've seen no reports of thermal throttling and no issues myself
If you are using Ex Kernel Manager, under the CPU section, you can adjust the Thermal Throttling temperature in Celsius. I have no experience with adjusting it though.

can you share your underclocking settings? there's no discussion about it in the exkernel thread.
also, did you figure out anything that helps with the heat? it's really well documented that this phone does throttle like crazy, so not sure what everyone saying it's just fine is talking about.
"it’s required to throttle to about 50% of its peak performance for most of the duration of the test to maintain reasonable skin temperatures" http://www.anandtech.com/show/9820/the-google-nexus-6p-review/6
Delete thermal.conf file in system>etc I believe. Disable msm_thermal and core_control in the elementx app. No more throttling. My phone has gotten hot time to time but nothing to where I have reboots.

i don't have a thermal.conf file in that directory, but there is a thermal-engine.conf. What does deleting it do?
Also, I've found that if msm_thermal is on and core_control is off, then I get reboots while using android auto (phone call+maps+waze+charging for about 20 - 50 minutes). If I keep core_control on, then it doesn't overheat. Also, with just msm_thermal on, and core_control off, I've found that gaming performance degrades, while with core_control on, it doesn't.
So I appreciate the advice, but I need some more discussion/explanation of what exactly that would do. Like if I turned both msm_thermal and core_control off, is there something that would prevent the phone from over heating?
Phone: VS995 Rooted running WETA rom + Werewolf Kernel.
Issue: Phone heavy CPU throttling when charging, gaming or even just booting. The CPU throttles to 652mhz on the small cluster and 1036mhz on the big cluster whenever I do something cpu intensive for a couple minutes. Obviously this causes a lot of stuttering and lag. I have to let it sit untouched and it will go back to normal.
I've monitored the temps and CPU doesn't go above 50c when playing games and my battery temp is below 25c. Even if the cpu temps go back down to 35c, it takes a while for the frequencies to ramp back up to max.
I'm using EX kernal manager and have disabled core_control and msm_thermal but doesn't help.
I've tried the stock WETA kernel and Werewolf kernel but they both don't seem to affect the heavy throttling at all.
Wondering if there is a kernel or a fix for this, kinda like the lg g3 thermal mitigation setting, or the CTTMOD found on other devices? Or maybe my device needs to replace thermal paste?
Thanks!

I've noticed this as well on WETA but only when charging. For some reason on WETA on stock kernel this phone slows down dramatically when plugged in. I just thought it was LGs method of thermal control but on MEGAROM V4 it doesn't slow down at all for me when plugged in so idk but would like to know how to fix cause I have it plugged in during driving a lot and switching back and forth between music and navigation becomes frustrating because of how laggy it gets

Yes! That's exactly what I'm experiencing too.
Having it plugged in throttles the cpu immediately. Doesn't matter if it's a quick charger or a slow charger. The battery and CPU temps are both low so that's not an issue. Even when it reaches 100% battery and just trickle charging, it still throttles randomly.
I'll start a different rom and see if it helps.

Having the same issue
My phone always stay Cool even when charging but cpu frequencies keep changing.
Even when i set the cpu max to 2105mhz it automatically slow down to 1036mhz , which makes the device super laggy and shuttering.
I've tried stock rom,weta,and some other roms and also tried some kernels nothing seems to be fixing the issue but Resurrection remix rom fixed it, no frequencies changing no lag no shuttering but i also has a problem that second screen doesn't work at all :/
yep same issues stock here.. just made a topic and realized you made this lol. stock rooted fwiw. I can't stand it. this phone has become such a lag fest that the galaxy s6 I was given for work seems faster, and that's two years old.
