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.
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.
How to tweak this kernel for stopping G2 from overheating? Even I lowered my CPU to 1ghz it is still overheating. :crying: please help. thanks
Hi,
What is exactly overheating for you???
Can you share your CPU/battery temperatures?
Overheating... But when? When playing a game while downloading a huge file over 4G and while charging?
viking37 said:
Hi,
Guys you realize that you have a quadcore at 2.26 Ghz... And when you play a (heavy) game or some other heavy tasks (browsing in 4G for example) it's normal that the CPU heats, right?
Temperature is very subjective without reading the CPU temp with an app, it feels hot in your hand (you can have cold hands and in this case you feel much more the heat) and it's hot because the CPU temp is about 90°C is different...
Heat and overheat (or "maximum overheating" like above ) is different too..., in any case there is a thermal throttling that prevent overheating. Our CPU shutdowns at 120°C so there is a little room... Even 80°C is nothing for the CPU...
Even 90°C for the CPU temperature is almost nothing (for the the stressed people) and there is a thermal protection in any case. Thermal throttling that reduces the CPU freq according to the CPU temp, same thing for the battery. And in case of extreme temperature -> shutdown.
And if you speak about "overheating" when playing a game or browsing while charging your phone...
Check your CPU temp with an app and report here...
It remembers me all the threads about "overheating" in the Nexus 4 forum...

After that you can try to undervolt a little (be carefull, step by step and don't set your undervolt at boot unless you're sure it's stable) and play with the thermal control by decreasing the max CPU temperature before thermal throttling...
You can use an app like Trickster Mod or Faux123 app (kernel enhancement) on the Play Store.

After playing heavy games, I can use my phone to iron clothes. lol. Well, I know it have quad core that's why I bought it. And I think having this kind of power is a disadvantage too because it heats very quickly like 10mins of heavy gaming.. And by heating it decreases the battery life.. I don't want to use this quad core phone in just browsing and watching video only, i bought this for gaming also.. lol
I don't know now where to use these quad cores.. lol... I envy my brother now, playing games smoothly on his ip5s with cool temp.. >.<
I have fauxclock and leave it to Intellithermal frequency throttle temp:80c and core throttle temp 85c. Is that ok?
Thanks :cyclops:
Re,
Hummm..... :laugh:
Decrease the two temperatures of 10°C... And use Ondemand or Interactive governor with MpDesicion "on"...
Try undervolt/underclock a little... No need to underclock at 1 Ghz otherwise, right, it will lag...
But I don't think you really understand what I was trying to say... Heavy games+quadcore 2,26 Ghz+10 mins of use with that...= heat (and not overheating), are you sure there is something wrong or abnormal?
What is your CPU/battery temperatures???
And please don't compare our CPU's with the one in the Iphhone 5, it's not the same thing.

I think its totally heat. But is it ok to heat it for like 1hr straight? Will it decrease the lifespan of my battery?

Begin with -25 mV but don't set at boot, use your phone for a day like as always (games, browsing, etc...). If you don't have reboots or anything wrong then try another step by - 25 mV. If you went too low your phone will reboot, (so don't use the set/apply on boot setting or you could have a bootloop), at this point you"ll know the undervolt possibility. Apply your last setting before the crash and see...
I don't know what we could do more... I think you need to read a bit more

Heloo i have the same problem when i play games likeplants vs zombies my phone hetas badly imen like 70°C(160°F) and i dont think it normal in like 10 to 15 min to be like that,i have root andtrickster app instaled and i alawys check the temperature.
I know its normal for the phone to heat but not so fast i seen thrads where users reported theyre g2 doesent heat bad att all.I have cpu threshold. on ,activated it from secret men.
So please helpwith advice and youre experience with this problem.
Thank you!
Hi,
Strif3, it's normal, point. 70°C is the CPU temperature limit before thermal throttling. What can I say more??? Read my posts above...
Use your phone like you want, as usual in any case there is a thermal protection! I think that Qualcomm knows how their SoC needs to be set about thermal stuff and I think (I'm sure) you can play heavy games without any issues even if your phone is at 70°C.
If your CPU temp was at 100°C (without modifie the thermal throttling), ok maybe here there is a problem (it depends also what you are doing), but I repeat 70°C during a game and after 10 mins i's totally normal!
If you all guys are worried about the CPU temperature, stop playing games, browsing in 4G and underclock your CPU to 300 Mhz and all will be fine...

Aha i understand i must mention the cpu frequency at 70°C is like 1Ghz but no loss in performance and in browsing,music and youtube no heating problems.Just wanted to know its not a issue with my phone.
Thnx for info
Hi. I wonder Hidden menu
Thermal Daemon Mitigation OFF
And
High Temperature Property OFF
Settings are what for?
Is that must be on or off?
Sorry for my bad english.
Hi,
For the second setting, take a look here: http://forum.xda-developers.com/showthread.php?t=2479892. It's related to thermal throttling (higher CPU temperature limite before thermal throttling than "stock"). It helps during benchs or heavy games and it seems it helps for those who have lags. The CPU freq is not agressively decreased ( at least lesser) according to the CPU temperature like with this setting OFF.
For the first setting, I try to turn it ON but I encountered some hard reboots during benchs for example so I leave it off. I think it disables the thermal throttling (not sure).

Battery drain?
Is that settings causes battery draining?
I was used that setting for 2 days and my battery drains fast i guess.
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?
