Nexus 4 overheating

I just recently got my nexus 4 and I love it there is only one gripe I have which is the CPU temperature ... I ran various tests using stability control test and just gaming . I ran stability test for 30 minutes and got the following results ( below in pictures ) .When I game for an hour it hits 48-52 C . Is this normal ? Will it affect my CPU in anyway ?

The heat causes thermal throttling. That will reduce performance. Undervolting helps with this a lot.

theres nothing wrong there, its all normal.

I don't think those temperatures mean overheating. It is indeed quite warm. It is exceptionally warm but not hot to the touch that you can't handle it.

So is there a fix for this ?

Where are all my computer nerds to stop all these rediculous overheating threads? 40*C in COLD for a processor. 60C is fine. It'll throttle it if it gets too hot. Come back when you hit 90C. Not trying to be mean but jeez, someone needs to open up their computer and feel how how your processor or GPU heat sink is just at idle, you'd get second degree burns touching the heatsink at full load. Its normal for processors to get hot... to a point.

The only reason why I asked this question is because I am still new to this device, but you can't really compare a desktop cpu or gpu to a smartphones cpu/gpu.there two distinctive hardware. PS, I work with computers and a computer science major

RMA it. Don't forget to flash it back to stock first.

What you see in System tuner is the CPU temp and the temperature you see in stability test is the battery temp. Those temperatures are completely fine and actually really cool for this device. Now if the battery reaches 48-52 Degrees C now we have a problem. I suggest using a custom kernel and ROM to allow some undervolting for none to less throttling so your performance will not be impacted. Should give Trinity kernel a try, latest ones are USUALLY in simm's G+ page or go to the Trinity kernel thread and download it from the website. Hope I helped

Ohh no the battery's max was 40 only the CPU hits 48-52 , for me its not a problem. I just wanted to know if it was safe to continue to game.

Overclocking

Hey guys, just wondering what the maximum frequency our Snapdragon S4 Pro CPU's can handle??
Thanks peoples lol
Sent from my Nexus 4 using xda premium

What's the point in over clocking on the n4? Are the improvements actually noticeable for anything besides bench testing? Meaning is it noticeable when doing day to day activities? The reason i ask is because my phone has handled everything I've thrown at it with no issues so far.....just curious I guess

I see absolutely no point in over clocking this device, even under clocking the nexus 4 you get plenty of power.

If you use trinity kernel, you will be able to oC to 1.8Ghz. It used to be able to OCable to 1.9 but I think there were substantial issues with that level. Overclocking will ruin the CPU life span. Overclocking is more suitable for computers. This phone is really quick and smooth out of box. Overclocking it is redundant.

Does anybody here even understand what overclocking is?

Why oh why do people feel the need to overclock a Quad core device with 2 gigs of RAM.

Good question but, to answer the OP 1.94GHz is the max. More may be possible however, no one is foolish enough to risk 2Ghz+.

Okay let's set this straight:
More Overclock --> Faster speed --> Lower stability
Increasing Voltage --> More stability --> Higher temperature --> Dangerous
To be able to achieve a higher clock speed, you need to have a higher CPU voltage in order for it to be stable. If you don't increase the voltage, the CPU will churn out corrupted data, and in the worse case files will become corrupted as they are written into memory. But it WON'T damage your hardware. However, because you are increasing the voltage, you get more heat, which can damage your hardware. So it's actually the overvolting bit that is dangerous, not the overclocking.
As for maximum clockspeed, you might find this article interesting:
"Theoretically, your upper limit would be due to the propagation delay in sending electrons from one point to another, which would be the speed of electricity. Electricity travels close to the speed of light and light travels a foot in a femtosecond (10E-15 s) so the top speed is somewhere in the 10E22-10E23 Hz range. However, this limit will never be reached as this assumes no capacitance and no resistance in the wire."
- Source: Mu_Engineer (http://www.tomshardware.com/forum/250325-28-limit-clock-speed) -
1 GHz is 10E9 Hz, which is nowhere close to 10E22. Even taking into account the resistance of the circuitry, 10E9 is still very low. So 1.94 GHz is simply the maximum STABLE clockspeed you can normally achieve on a Nexus 4. In addition, developers might impose arbitary limitations on how much you can overclock your CPU, but that's just a software limitation.
In conclusion, the answer will depend on which of the following questions you actually want answered:
1) What is the highest stable clockspeed the XDA community has managed to achieve without external aid (i.e. liquid N2)?
2) What is the highest clockspeed allowed by currently available kernels?
3) What is the physical clockspeed limit of the Snapdragon S4 Pro assuming external aids are allowed? (E.g. connecting your CPU to a higher voltage source directly while keeping it cooled with liquid helium. Even then it would probably only lasts for a few seconds.)

Why don`t you overclock it yourself and post your findings here, overclocking the N4 is useless imo and only nice for those kicking on benchmarks.

I won't because at the moment I fail to see any reason why anyone would need to OC their Nexus 4. So yes I am agreeing with you.
However, OP asked for the highest clockspeed, not for opinions on whether OC is useful. Saying that OC is useless in response to his question is similar to telling someone that they should eat at Burger King instead when they ask you for directions to MacDonald's. It doesn't make your statement any less true, but you are not answering his question.

With some Kernel like Faux you can OC up 1.94Ghz (Turbo Boost Ultimate) but not all CPU hold this frequency.
I think 1.83Ghz (Turbo Boost Mainline) is more reasonable.
Both Kernel just mentioned also OC GPU to 487Mhz.
Personally i don't Think we need to OC our Nexus 4, I've never seen a phone so fast

[Q] Nexus 4 GPU Frame Rates Drops

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.

Cpu temp concern

I'm using franco 165 and I undervolted 100 on all steps my cpu hit 50 Celsius or 120f I dropped my phone twice now in the official bumper I have a better case I'm gonna switch to but two part question.
#1 does dropping device damage the cpu mounting causing overheating or stuttering
#2 is the cpu at 120 running hot? It's at 94-96 idle

Another one of these threads.... Holy cow.
Yes the N4 irradiates a good amount of heat and does get quite hot at times. Its totally normal.
If your search you'll find many many many posts of this topic. Some people believe its overheating. I my self think the high temps in this device are normal and haven't caused me any issues even overclocked.
Sent from my Nexus 4 using xda app-developers app

50°C for CPU temp is well within the normal. In fact that is pretty cool.
Mine is currently at 43° and only used for less than 1 minute.
Points for concern are CPU > 80°C
And battery > 50°C
Anything below is nothing to even get concerned with.
I will state the info I have given to others previously.
With defaults the phone will start to throttle at CPU 60°C or battery 48°C, this is what is classed as running warm.
From then you have up until CPU 100°C or battery 60°C before the phone will power off because it's running critically hot and needs to cool to prevent damage.

Nexus 4 thermal throttling fix

The nexus 4 is definitely a great phone for a low price.But people are not buying this phone because of this THERMAL THROTTLING.so,people listen nexus 4 even runs smooth with thermal throttling going on.so, this fix is for people who just dont want thermal throttling.Before we start,this fix requires ROOT and a custom recovery.And a custom kernel needs to be flashed.so if you do any damage to your phone by doing this,I'm NOT RESPONSIBLE.
So first download the faux kernel for nexus 4(codename mako. if you see mako on faux website its for nexus 4) from here: Faux's website which i cannot post because im new to XDA. you can find it by googling for faux kernel website.I recommend the TBM kernels such as mako-jb-kernel 016 tbm which lets you overclock CPU to 1.83 Ghz.But theres also TBU kernels which support overclocking to 1.94 GHz.
Step 1 now download a faux kernel of your choice.
Step 2 paste the kernel to your mobile
Step 3 Boot into recovery mode
Step 4 Wipe cache
Step 5 Wipe dalvik cache
Step 6 Install .zip kernel
Step 7 Reboot your phone
Step 8 Now you have to buy the faux123 kernel enhancement program from play store(this app is from faux and this has intelli-thermal built in it)
Have fun.the faux app lets you select CPU frequencies also

What.

With his enhancement app yes you can control throttling but the problem is that because the phones CPU is getting way too hot, so increasing the throttle threshold or limit basically makes it so when your gaming, it makes things smoother however your CPU is burning faster.

No it has a thermal manager which controls the heat.if it heats up it automatically turns off 1 or 2 cores so that means 2 cores wil still run normally but the other 2 cores will shutdown.
Understood??

i always turn off throttling, on every device i own(ed). they all live long lives, and are the best performers around(for their model). they never ever got damaged because of it, and im an extrely heavy user. my n4 has had all throttling disabled since jan 14th, and its still going strong. the difference is that i never complain that my phone turns down cpu speed, or does my phones performance get slowed down.

The nexus 4 throttling is caused by the battery reaching a certain temperature not the CPU. It's poor design/cooling system causes heat to build up which raises the temperature of the battery. Once it reaches a low 37 degrees the cpu/gpu are downclocked even if they are well within their limits.

the n4 has a battery temp throttle AND a cpu temp throttle.
i generally disable both the battery and cpu temp throttles, but leave both safety temps as is. for those that say "oh, the extra heat will eventually ruin the phone".. the temp doesnt get any hotter than it does when you normally use your phone, the difference is that you dont get throttled. and even if there was extra heat because of, im not planning on having my phone for the amount of time that the extra heat will take to ruin the phone(years).
