Hello Guys, i registered to XDA developers to ask this question so please reply. i heard many say GPU of Nexus 4 is very bad because after 20 mins of gameplay the phone gets heated and the GPU performance is Dramatically Reduced to cooldown. I am going to buy Nexus 4 thats y im asking, i didnt hear this from my neighbours..., i saw someone say this in youtube comments. Anyone Experiencing this Issue? or its a defective product?.
This is a good thread to read about Thermal Throttling: http://forum.xda-developers.com/showthread.php?t=2144652
I am not sure about the GPU actually reducing it's power when the nexus is getting hot. I know the CPU will clock lower when it has reached 70 degrees so it can cool down. Most kernel's have the ability to up this to about 100 degrees so you won't have the thermal throttling as fast. You are also able to remove the throttling completely with a commando.
I've played alot of Dungeon Hunter 4/GTA Vice City/Real Racing 3 and I have never experienced severe FPS drops because of it getting hotter. The only thing you will experience is a battery that will be empty within 2 hours.
PS: This is based on what i've read on the forums, I do not have my nexus 4 for that long and I am not a developer, someone might be able to give you more accurate information.
The thermald.conf sets the battery threshold to about 40-41C before it begins to underclock aggressively (hence why it feels sluggish). I forget the exact number. It starts reading "Overheating" status when it reaches about 46C. Max rated temperature for the battery is 60C.
At that battery temperature ~41C, the CPU is no more than about 50C, so it's not the CPU overheating.
If you feel so inclined, you can modify the thermald.conf with root to modify how aggressive the thermal throttling acts, within reason. Otherwise you'll cook your phone.

or you can run a custom kernel(like trinity) that disables the battery thermal throttle and not worry about it.

YMMV with that. My nominal binned SoC overheats really easily. With the way I use my phone, it'd be overheating way too often.
I modified my thermald.conf so it's less aggressive. It's not that hard to figure out.
The phone throttles its clock speed like a PC. It's not a big deal.
Stuck my phone in the freezer for a few minutes, took it out, and ran the stability test in AnTuTu which plots the temperature and a benchmark score. Looks like it starts right around 34 degrees (93 Fahrenheit), which really isn't that warm at all. You could get that just browsing around and holding it in your hand.
My cpu temp is normally in the 40's and 50's while browsing.
Have you tried turning the thermal daemon mitigation and high temperature property off in the hidden menu and see if this throttling happen? Will be interesting to know if the hidden menu selection works.

It does work. you can just open an app like setcpu and you'll see that it rarely peaks without disabling throttling. Just be careful as it does open you up to potential hardware failures and shorter life of the device. I only keep phones for around 6 months so I don't care but I'm not a normal usage case.

Wouldn't the hardware still have a thermal cut off point where it will just shut down the phone if it gets too hot? It's to my understanding that this hardware shut off point is different than the software thermal throttling. If anything, I think it will just make your device get too hot for comfort than do any real hardware damage to it.
I'm just throwing an educated guess out there though, I honestly have no real proof one way or the other.

Yes eventually it'll hit tjunction and shut down. This isn't even a safe shut down though. It is basically an emergency kill switch. It's like yanking the cord out of the wall on a desktop. Running at higher temps also shortens the life of the silicone. Much the same effect that overclocking has on a normal PC.

If it gets hot, it will do damage. It can fry the GPU before it even gets to shutdown point. The XBOX 360 for example had the RROD where the constant heat made the solder joints fail (I know the 360 is different but the heat point stands)

The 34 in this case is temp or battery, not SoC. The SoC is probably hit 75 Celcius and that's why CPU throttles. Try HWBot bench instead, it shows not battery but CPU temp. You will see that CPU immediately hits 75°

Afaik they shut down itself if battery hits 60°C or CPU burns to smthn like 105C
HWBot runs parallel... If you want to see your CPU get really hot press the button multiple times. Phone melted!
Why does the snapdragon get so hot. I don't understand what's the point of a fast chip in these phones if they can't run on there maximum lol.... Maybe that's why Intel is gonna take over qualcom one day.

It runs hotter because its having to produce all the pixels for the QHD. The same chip in other 1080 phones doesn't run as hot. At times doing normal things like browsing and Facebook etc my phone has throttled down to 1.4Ghz max and the CPU temp is up at 65-70deg C. That's pretty hot.

Its not the only phone. And mine never throttles that low doing normal tasks. It doesn't even throttle at all. However, when playing games or running demanding apps it does throttle.
Also, its not the only phone that runs this hot. All other phones will get hot and throttle just as much when running equally demanding stuff.
So the question was, what's the point of super fast chips when they are going to throttle themselves so fast?

I'd recommend that you do a bit of testing,run some apps for 5-10 min then open up a CPU frequency app. The frequency will be be at a low maximum and the temp high. The GPU also throttles, open an app like Faux clock after running some apps and the max GPU value has decreased. Without a doubt the extra pixels are causing this as the SOC is having to work harder to produce them. Its simple physics.B
But anyway, its a specs game. People want faster and better so that's why the SOCs get faster and faster even if they're throttling.

The soc is working harder, but like I just said the how soc is still hot even on other phones man.
Run the dead trigger on the s5 and the g3. They both most likely throttle down to the same limit while the fps on the G3 might be a little lower due to the resolution.
But like I just said, what's the point when the damn thing will burn. There is no point in 2.5ghz when your phone can't run at that frequency more than 5 seconds lol.
I remember when I used to run my Galaxy S One full speed. Not one but of throttling. These CPUs have not gotten any more efficient thermal wise.

Yeah, I agree there's not much point in having a super fast chip when it throttles so much. Again, people want bigger faster and better and most users wont even know about thermal throtlling.It does seem to be bad on the G3 though. I think I saw another thread that said LG don't use a proper thermal pad also. Don't know about that but to run a 1080 phone with the same chip as a 2k phone then you'll have thermal and performance issues on the 2k Vs the 1080.

The 801 is more than capable of driving a QHD phone. The 800 series are basically created to support up to 4k. And how will give the same performance as a 800 while on QHD. Its not even close to being a big deal. And yeah I saw that same thread. I wonder if it's true.

I see that the layered CPU/memory unit has a metal cover to it, im wondering if a thin thermal pad could be placed between them to conduct heat to the metal cover. Its not much of a heatsink, but it might help a little bit. It may even be possible to put a thin copper sheet on the metal cover to move heat away. It all depends how much room there is under the plastic cover. The only teardown ive seen doesnt make it very clear.

To the extent that flickering and low charging is related to Sony thermanager, here is the permanent fix for AOSP/CM based roms. While the idea of thermal manager is good and we should credit Sony for doing it, the implementation kind of s*cks. For example, the manager kicks in when CPU/GPU temperature rises to 44 degrees. Also, several triggers are set between 54-56 degrees. This is plain wrong, because 44, 50 and 55-56 are all perfect numbers for an active device and at these temperatures, thermal manager should not be active. I have adjusted trigger numbers so that there will be no mitigation until at least 60 and surprise surprise, all screen flickering is gone away....
Attached is thermanager.xml which should be put in /system/etc/ with 644 permissions. Reboot is required. UNZIP FIRST. Also, backup your current file just in case.
A word of caution on undervolting: keep in mind that when you undervolt on high frequencies, you make your CPU work harder, as it requires more cycles to do the same task. As a result, you have overheating. So, undervolting is counter-intuitive..
Does it also will solve the touch freeze problem on cm12.1?

Any touch issues related to thermanager kicking in early could be resolved. But lollipop has overheating issues related to art, which can't be solved by thermal management. That's why strictly speaking, lollipop has to be recalled. In my view it can't be fixed.
A little question
Hello optimumpro
I only need put the thermanager in the path system/etc to make it work? or need something else?. Sorry by the queastion I noob an recently I repair de display and touchscreen for my xperia z1 C6902 and a have the flickering problem.

I think you have a misconception about undervolting , undervolting does not make your CPU work harder , instead it makes your CPU unstable .
so no, undervolting does not makes your cpu overheat , only overvolting does.
This works for me!

You are probably on kitkat. If that's the case, you don't need thermanager. If you are on lollipop, look again, the files are not necessarily in alphabetical order...
And remember, this one is for custom roms: CM and/or AOSP based. I just looked at your signature, you have stock...

You are wrong. When cpu is unstable, it can't do the job. When it can't do the job it jumps to higher frequencies and then plugs in additional cores, which causes overheating.

Explain why that a phone reboots automatically when you underclock too much, if your concept is correct then it should just run at higher frequencies instead of just reboot.
And also what's the purpose of overvolting?
What's the purpose of per frequency voltage table?

Easy: when you under volt over a certain level, the cpu just shuts down, because it does not have enough energy to jump to higher frequencies. So, in that case, instead of jumping and overheating, it just dies. However, when you under volt to a lesser degree and cpu has just enough (not to die), then you will have jumping and overheating.
There is no purpose in overvolting, other than returning to your prior levels or correcting wrong default values if you don't want to fix those in kernel source.
What's the purpose of per frequency voltage table? If you adjust, you want to do it on global level, because cpu has different frequencies. There is no other way...
However, if you put your phone on performance governor, you won't need per frequency voltage. By the way, in my experience, performance governor causes less noise and overheating, because it does not spend time and energy on jumping, and it could go to idle immediately.

Advantages of undervolting Android
Thank God for Android where we can easily modify and customize our lovely Android devices to the way we want. Being said this, undervolting is one of the biggest attraction for Android! Simply by undervolting an Android you will or might experience:
A longer battery life
More responsive smartphone
Less heat produced by the phone
Super-charge your Android to go further than what it can do (overclocking Android)

Note: UnderVolting is widely used as a cooling solution and in my opinion more effective than any other cooling solution available for free. Results can will show decrease in the temperature of smartphone. I recommend undervolting to anyone with enough confidence and knowledge to do so. The benefits easily outweigh the risks. I dont see why one shouldn’t do this for a cool and better smartphone experience.Undervolting will NOT compromise performance at all.

Maybe or maybe not. Blogs, especially by those who don't know what they are talking about (isn't it the purpose of blogs anyway? ) is not proof of anything.
However, you asked me to explain myself and I did. Why don't you put cpu info on the screen and experiment (so you can see live frequencies and temperature). You'll be surprised...
The point stands: when your cpu does not have enough juice, it spends more efforts to accomplish the task. If it manages not to shutdown, then it spends more cycles to do the job, thus causing overheating and excessive battery drain. And it does not matter how you call that state: unstable or whatever...
The reason I said it was counterintuitive is that people think if you provide less energy to cpu, there will be less noise and heat. The most energy is spent when cpu jumps back and force or plugs in/out cores and that's exactly what cpu does when you reduce voltage. If it is locked at the highest frequency, you eliminate jumping and extra plugging. When your phone is active, it accomplishes tasks faster. When it is done, it rushes to idle immediately and in idle state it virtually does not make any difference which frequency you are on, especially it does not matter when your phone is in deep sleep. Also, at higher frequencies cpu is often able to do the task using one core, again resulting in battery savings.

"You're the one who don't know what you yourself is talking about"
No need to get personal. And I certainly don't need any "favors" from you.
If you need proof, just do a search anywhere including XDA where it would tell you that there is growing evidence that performance governor where your cpu is set at the highest frequency reduces "race to idle" and therefore causes less noise (jumping) and therefore better on performance and battery.
http://forum.xda-developers.com/nexus-4/development/guide-android-governors-explained-t2017715 That's just one example.
You won't find much more for several reasons: linux does not care about smart phones and only they know enough about kernels, but in the context of PCs they are not concerned about governors. They only have performance and ondemand (for laptops). Google does not deal with kernels (except for nexus) and they have no qualified engineers. Manufacturers do, but they have no incentives to invest more millions in research and development so that you can keep your device longer.
But as I have already said, do it yourself. Set cpu data on screen and experiment with performance vs other governors while watching the temperature. My experience has been that there is obviously no jumping and very little core plugging/unplugging, because 2.2-2.4 core can do a lot alone without extra efforts...
If you can't behave and maintain an intelligent conversation without resorting to personal attacks, then there is no point for me to talk to you. .

I am not attacking you tbh.
Governors doesn't do anything besides controlling the frequencies of cpu. CPU uses correct amount of voltage according to the voltage table.
If what you're saying is correct, doesn't overvoltage makes your phone cooler? It has more energy to process things and doesn't need to jump to higher frequency right?
Kernel developers implement features for reasons. If your theory is correct, why does voltage control exist? Does kernel developers write a thousand lines of code just to do nothing?

"I am not attacking you" Yes you were, I said that some bloggers don't know what they are talking about and you replied that I didn't know what I was talking about. Anyway, I accept your veiled apology.
Neither overvoltage nor undervoltage makes the phone cooler. There is an optimal regime for each cpu and if you go outside of it (in either direction), you are inviting trouble. You are not going to destroy your cpu by either under or over voltage, as there is protection in kernel. The phone runs cooler when cpu works less and the optimal regime causes the cpu work less. If you are reducing juice (voltage), you make cpu work longer, which results in overheating.
I gave you an example of performance governor to make a point that this is counterintuitive: while cpu is set at the higher frequencies, it actually performs the tasks and rushes to idle faster, which results in cooler condition. When the same cpu is set lower (and especially if it is under volted), it works longer, jumps to different frequencies, plugs/unplugs cores, which all contributes to overheating....
What is normal values for this phone ? I have diferent chargers, Samnsung - around 600mA, one HTC - around 400mA and another one with 200mA according to that app. Wich one should i use ? So far i used samsung one because it charges fast...2 hours or less, but the battery dies also fast ....so it may be because of the charger ?
Hey guys not to good at understanding this... I ran a throttle test because my phone keeps getting extremely slow... After the 10 min test it said my CPU was throttled to 48%... I am fully stock (Tho at one point i was rooted) and running Android 8 OREO on H910. I added a video of the throttle test. Could this be thermal related? I don't mind tearing the phone apart to replace thermal compound but if it wont do anything then why waste time right?

Did your phone get noticeably hot during the throttle test and was the plugged in and charging during test?

It was not plugged in. It did get hotter during the test which i thought was normal considering it is loading the CPU's.
Side note... how come my first core does not get as hot as the other 3 cores? is there a reason for that?

Not sure but I have noticed that the CPU temp monitors are extremely inconsistent. I've had 4 tell me completely different temps than each other. If you wanna try a few mods before you try the thermal paste then I would suggest the thermal throttle mod which is only really supposed to help when charging but maybe it'll work for ya and try the MK2000 BTTF kernel if there is one for your model. Those have both helped my H918 and runs great even in hot climate it doesn't throttle.
Even so it's prolly a good idea to get the thermal paste ready for a change as my stock paste was pretty much completely solid. Cheap stuff whatever was used.
Just saw you were on Oreo. Most of the mods aren't available for Oreo yet or haven't been updated or tested so if your still on Oreo you might wanna hold off on the mods or at least make sure you backup the appropriate files before doing so. If you are still on Oreo that is
I have installed the thermal mod, and my cpu heat is about 50 celcius. Is it very harmful to the cpu?

What mod ?
Mine avgs 24c to 30c, 50c seems a bit high. Seems like you have something running in the background
here's a screenshot of my thermals

the problem is not much in the CPU as it is tested for higher temperatures but for the battery ... as the heat is definitely deleterious ..rather than putting mods (which modify the thermal) I recommend a good custom kernel or alternatively if you want to save battery use morpho (ex spectrum) obviously you must have the root

Sorry for late reply, I am busy recently. I am using Jthermal-Mod

I know it will harm the battery and cpu, I installed thermal mod because of the frame loss when I am playing pubg or other heavy game something like that.

i've been using my note 7 with thermal mod for about 6 months now, and the highest temp i ever got was 47°c and that was me playing pubg on extreme+smooth settings with the charger on. be very careful when playing on high temps for long period of time as it will destroy your battery like it did with my redmi note 4.

Thx. I've tested it but I suppose it could give gain in performance while running MIUI' roms. On my CR Droid rom, it seems worst with it...

ok but guys do you realize what you're doing? if you play games that require a lot of resources it is obvious that the CPU and GPU heat up now if you didn't know there are pads specially created for this ... they cost about 20 euros, you place the phone in this pad and behind it there is a fan mounted and in addition there are function keys obviously it connects via Bluetooth, and for those who love these games it is the only real solution especially if you spend many hours playing, I have never had thermal problems indeed actually on a leEco the 2 yes but it was a problem that was due to the charging settings too aggressive. so since changing a battery today is not easy and above all it is better to save the phone with one of these pads ...
