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.

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.

I just noticed, coming from the S3 my N2 runs relatively cool. Battery temp is 27-38 degrees celcius even when playing graphic intensive games while tormenting. While the highest cpu temp I saw was 53. Compare this with my s3 battery temp 36-48 and cpu temp 60.

There will be risks and you have to constantly monitor your settings (i.e. watching the temperature, battery life), but generally overclocking (TO A LIMIT) is safe. There are a bunch of kernels out there already for the nexus 4 that have preconfigured OC/UV values. You can check them out here: http://forum.xda-developers.com/showpost.php?p=33746072&postcount=3
Personally, I don't see the need to OC the phone; it's already very powerful. Doing so would only decrease your battery life.
klvnhng knows what's up.
Heat is the killer of electronics. By introducing more, you risk issues either in the short or long term. And as he said, why? The phone is a beast.
Overclocking a krait is pointless, that's too much power that's going to be wasted heating up the already temperature sensitive device. Not only that but, the s4 chip is extremely fast you won't even a difference between the dual and quad versions.
Thanks guys decided to leave it as it is. Thanks for the key points. "THANKS" to you all

How many of them had li-po batteries? Li-po batteries are more susceptible to heat damage than li-ion. Anything above 60°C is potentially harmful to them.
I've had this device 2 months and have run it o/c'ed to 1.8.. Ghz since day one with no issues and no huge increase in battery consumption. It doesn't always stay at that clock speed, it's an "on demand" thing.

I'm not talking about battery consumption. I'm talking about the longevity of the battery due to higher heat generated by higher clock speeds. If you're able to keep the temp below 60° by undervolting and careful use, then it's fine. I'm just offering a word of caution to whoever wants to O/C.

Hi, I've lowered all the figures by 100mv, but I notice no difference in my battery life. Is it safe to lower the figures more?
Sent from my Nexus 7 using xda premium
Define what you mean by "safe".
Higher core voltages are used at higher clock rates in order to preserve logic margin in the face of more power supply noise and tighter timing. So, undervolting by definition means you are giving up margin.
Whether your SoC happens to have a worst-case timing path which is "fast" or "slow" relative to other devices cannot be deduced by anyone here on XDA or even at Nvidia. About the best you can hope for is some "feel good reports" about what others do with undervolting and completely undisciplined "testing". But even that provides no information about your individual chip.
good luck
Thanks for your reply. By "safe" I mean without damaging my device. And yes, it would be interesting to hear some undervolting stories. I'd quite like to extend my battery life. Cheers!

I've been using my nexus 7 runing a AOKP pub build by mrRobinson and franco's r47 kernel. i've undervolted the entire board by 100mv it is runing pretty solid without any noticible lag or instability. Yet every chip is diferent and can or cannot this margin you'll have to test for your self. Just leave the option 'set on boot' unticked untill your sure that your device is capable of using those kind of voltages. And don't use very large steps. Just like overclocking in fact! Try it - it runs - get a little bit lower. If it crashes you shoukd be able to reboot the nexus and the settings you've changed reseted

For what i've read that's the truth but if the frequencies set for the soc are getting less power shoudn't it draw less power from battery? 100mv its almost 10% of the stock voltages!

For the SoC, whether it's leakage (V^2/R) or dynamic power dissipation (f*C*V^2), yes, you might expect let's say (0.9^2) = 81% battery use at the same operating frequencies.
OTOH, if 75% of the power drain normally is used by the LCD backlight (for instance in a "reading web pages" use case), then reducing the supply voltage will get you only 1/4 of that 20% savings - about a 5% improvement - because the power is being dissipated elsewhere. (Display, DRAM, 3G radio, WiFi radio, etc)
I agree with what you've pointed! In fact i've just taken out the undervolt because Inhad a reboot under heavy multitasking (torrent download, xbmc opened, chrome also downloading a smal file) i'm not certain that it was caused by the uv but it's possible. The Nexus started to lag and then froze completly! From time to tima i've the need of heavy multitask and it wasn't up to the task!

Hi all I have spent same time in last days playing Real Racing 3. Very nice game.
While playing the temperature of my N4 became very high. It's a 1.5 quadcore with GPU working hard so it should be normal. But I saw, in system tuner, that while gaming it can reach even 70 Celsius. Is it normal this temperature in gaming or should I be worried?
What about your temperature in gaming?
PS: for the battery this game can drain all the battery in less than 2 hours, but even this should be normal because without gaming it usually reach 4 hours screen on, so 2 hours of hard gaming should be normal.
Let me know.

100C is the safety shutdown temp for the nexus 4, your phone wont melt at that temp. my gnex has hit 110C many many times, thats the shut down temp for the gnex.
you have to realize that there are two different temp readings, cpu temp and battery temp. while your battery reaching 50C isnt safe, 50C for the cpu is still relatively cool, and does not put your phone into danger.

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.

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).
