I just bought my Nexus 4 about 3 weeks ago, and noticed that it get considerably hot, and I mean, Reallyyyy hot, even when im not using.
So I've been trying out several roms and kernels and finally found the perfect solution and thought I should share it with everyone out there facing the same issue.
Just flash the latest stable version of CyanogenMod, and do not flash any extra kernels with it, leave it as it is, and notice the difference, it doesnt even heat up that much anymore, not even with extreme gaming.
Another tip, if u have touch control, or wave control installed, make sure they arnt working in the background as they keep the alot of sensors working even while the screen is off.
Just thought i'd share this.

problem is, threads like this keep continuing the falsity that the n4 has an overheating issue, when really it does not. its supposed to heat up with use, every similar device does, many even warmer then the n4. my question to you is, what temperatures did your nexus 4 reach that you are saying it "overheated"? cpu temp? battery temp? if it actually overheats, theres a safety mechanism in the device that will shut it down so it can cool off. plus, the n4 has that glass back, that makes it "feel" hotter than it actually is. if it had a plastic, carbon fiber, or metal back, you wouldnt really feel it.
also, very important, what is the air temperature around you?

This.
Guys, just google any smartphone powered by dual+ core+overheating problem+xda and I assure you will find similar threads. The last device I didn't feel much heat on was galaxy r with tegra2 1ghz. Everything more powerful than that was noticeably warmer. But honestly I really don't think that N4 gets warmer than my old S2.
Yeah temperature around you is very important. Let's say you ride the bus on hot sunny day and check some websites. It's not browsing itself that causes overheating, but the combination of few factors. The device is actually already warmer than usual when you take it out of the pocket.
If the phone was overheating, it would turn off. Yes, it gets warm, but not as warm as you think. You only notice it because it has a glass back. Mine isn't getting any hotter than my old nexus s. Under heavy use, it doesn't go above 45C, which is an OK temp.

To all three responses above me:
Fine it might not overheat to the point of melting or burning or even getting damaged but it does reach throttle temps and get uncomfortable to touch at times. Both of these are issues. Your phone should not be too hot to keep on your ear during a conversation, nor make your palm sweat excessively from holding it. It would also be ideal if your quad phone 1.5GHz phone stayed at 1.5GHz when under load. If it is forced to go below that, there is a good reason for threads like these.

My nexus 4 reached up to 77C. It never shut off or anything. I called Google and they said as long as everything still works its fine. I thought it was a lame answer but we will see. Battery got up to 56C.

1. Throttle temps are actual very low.
2. It's glass. Glass absorbs hest from the ambient air very easily ( it is summer for many) and from the inside of the device.
3. The phone shouldn't get to hot to hold to ear. I have never felt the display to be hot. Unless it was in direct sunlight.
4. All modern smartphone phones will throttle. Yes this one is more aggressive than most but they all do it. The amount of power all the modern high end chips can draw under load is the highest it has ever been. So they get hotter than ever. Since they are passively cooled, even the best designed phone under full load will throttle.
5. The only good reason for threads like this is to inform the user there isn't a problem. There are no issues.

thats the thing, its not a phone. its much much more than that. you ever feel how hot a laptop could get? anyways, i do agree with you with one point, that lg, or google, chose to set the cpu throttle temperature too low as a default. having root, i choose to disable thermal throttle, so i never have an issue with with my cpu being throttled down. i sympathize there with non rooted users. but thats only a software fix(the difference is changing a Y to a N in a file), thats not an issue with the n4 overheating.

My N4 get realy hot too, when i'm outside (38C-42C) i can't talk because it burns my years but i see MIUI and 4.3 the heatting issue is gone, i mean it's still hot sometimes but not burning.
I've got a Optimus Black when it first appeard and i got even hotter...
Actually, the Nexus 4 is more prone to overheating than, say, the almost identical Optimus G. Something about a small space in the Nexus 4 somewhere that doesn't conduct heat as efficiently away from the SoC, unlike the Optimus G.
However, like said before, it is summer for most people and it got hot in the UK, so your phone will be warmer than usual if left in the pocket or in the sunshine, but you can't expect to use a phone that's running at 55C-60C by only browsing, can you? Have you guys noticed the drastic temperature difference between wifi usage (low temps) vs data usage (high temps)? This pattern is present in most if not all phones but not as drastic as this, no way.
Then again, sometimes Franco's app is reporting 40-45 C and the phone feels really cool to the touch, and another moment, it's reporting 38 C and the back feels hot, so there's lots of factors that play in this.
Make sure you keep the phone out of the sun, and use Wakelock Detector to see if any rogue apps are holding a dirty wakelock doing lots of syncing especially over data (recent Whatsapp versions have been producing fullsync wakelocks with me everyday).
Disclaimer: other than hot weather and normal heating of the phone, i have not experienced any abnormal overheating, but have a friend who has. My normal temps are 34 C - 38 C, even in hot weather with most of my usage on wifi. Outside in hot weather gets to 42 C - 44 C but that's understandable.

this thought that coolnow just had..
feel doesnt report a temperature, feel only shows that something is warmer than/cooler than whatever body part you are touching it with. its all relative to your body temperature. try this experiment.. get 3 glasses of water, one hot water, one ice water, one room temperature water. at the same time, stick one hand into the hot water and the other in the ice water. keep them in there for a minute. now pull both of your hands out and stick them both in the same glass of room temperature water at the same time. this will mess with your senses, so be warned! the hand that was in the hot water, will feel the room temperature water to be cold, the hand that was in the ice water will feel the room temperature water to be very warm, while they are both in the same glass of water. so you see, reporting how something feels is very inaccurate and unreliable.
As simms22 point out about the feel, that is a terrible way to judge it.
Also so is the actual number from franco's app. His app measures the cpu (Soc) temp. It doesn't also include the battery temp. The higher battery temp will make the phone feel hotter even if the cpu temp is basically the same. Example when changing from the wall. It's also much larger than the SoC so it warms up a gesture surface area more quickly than just the SoC.
It's also located on the middle to lower part of the phone where it is more common to have your hand. Compared to the near the top / camera location for the SoC
Another thing that is obvious but I never mentioned. Is the phone is black. A black glass phone in summer sunlight ( on a call holding the phone up to your ear) will get hot. Even if the thing was turned off.

That's exactly what i'm saying, reporting what you feel, especially on a glass backing that the Nexus 4 has, is inaccurate (and everyone who went through highschool biology knows our sense of temperature is just a measure of temperature difference).

In case you didn't notice, Simms22 was not arguing against you but supplementing your arguments instead. In layman's term, you are both playing for the same team. So stop fighting amongst yourselves.
At this point I think we can all agree that in terms of actual temperature the Nexus 4 is not (much) hotter than other phones with similar specs. However, there is probably something about the design and/or materials used that causes people to worry (and complain) about the phone overheating. Now if you good folks want to figure out what actually causes the phone to "feel" hotter in comparison to other phones, feel free to proceed. I have no doubt that it will become an interesting topic.

really, i wasnt arguing with you, i was backing you up, explaining, because unfortunately most people dont know that feel is just a measure of temperature difference.
what i think the issue is, is that lg(or google) had the cpu throttle temp set too low on stock devices, giving people a noticeable reduction in performance within a normal temperature range, plus the whole glass back thing, therefore freaking out many. enjoying the freedoms of root access, i disable thermal throttle, so i dont notice any of the affects that the throttle would cause.

It is true that the Nexus 4 is heating more that other devices, it has been know even before its release. I had them too at first, when using heavy apps or games. But some roms and kernels make it heat more than normal because they are putting the cpu freq constantly at the max (1.5 GHz), that's why some users have problems constantly. I use the Paranoid Android rom, which is pretty light speaking of cpu usage, and franko kernel putting the max cpu freq at 1Ghz, also lowering the voltages. It helps a lot.
Every device I've ever had, htc desire, archos 70it, galaxy s2, galaxy s3, galaxy tab 10.1, nexus 7, nexus 4 and nexus 10 all have a new thread like this every week, just because the device "feels" hot. All our SoC are so powerful these days do have a high TDP and that's made worse by our SoC's relying on passive cooling. We won't have cool CPU's anytime soon, unless you want a fan or any other active cooling mechanism. Anything under ~80C is fairly safe for modern SoC's and isn't really anything to worry about. When you CPU get's too hot it will aid passively cooling by thermal throttling the CPU to a lower Frequency and if it carries on going up, then it will shut down before any damage is done. With all my devices I've done the same test, Undervolt, turn stress test on when SoC is at ideal temp and time how long it take to reach a certain temp. Repeat the experiment several times. I found that my nexus 10 heats up by far the fastest, thanks 32nm A15's and the nexus 4 was one of the coolest, only being beaten by my galaxy tab 10.1, 40nm dual core A9. To be fair, I do have a faster binned chip. Even my 1.4ghz exynos 4412 s3's core temp was higher than the n4's, you just couldn't feel it as much through the plastic. The nexus 4's heat dissipation even with the minor fault compared to the optimus G is reasonably good.
Hi all
I'm considering changing from Z to Z1. Xperia Z have some design flaws, The biggest one is heat issue. The heat itself is OK but it will continuously melt back glass glue little by little, then the phone will start to leak, so dust and water will get in. Is this problem fixed on Z1?
Another big design flaw on Z is headphone and charging port caps are easily worned out. Magnetic charger and cap free headphone jack would be good.
The only I find getting on my nerves is design flaw is the non scratch proof shatter resistance film on top of shatter resistant dragontrail glass on screen. I know this can be sorted out with a screen protector but I'm no pro when it comes to that and I always have bubbles some where on the screen

bull****! (with all do respect!)
glue of xperia Z melt by phone heat !?!?!
it is funny!
40-60 degree of C can melt just ice! not that powerful glue on xperia devices.
(however Cnet test it under HOT chocolate and nothing happened! and also a Japanese lady put it in hot water!)
one more thing;
for example that glue start melting when it warm up
but after that it becomes cool, from 60C to 30C and it means glue will return to their standard condition. cause glue are elastic!
i had Xperia Z for 8-9 months for heavy gaming and it means almost of time hot.
nothing happened.
anyway if u wanna buy new phone w8 for MWC and then decide wht to buy

Unfortunately, it really happens.
But you will never notice this flaw until you see dust in the camera or you put it in the water. You will see these issues on Z forum for sure.
I multitask alot with my beloved Xperia Z and sometimes it gets hot but i ignore it and it finds a way to cool down while i still use it.
My question is if its ok to drop it in cooled water when it gets hot OR is the temperature difference shift is to big that its not so healthy for the Xperia Z?
...and to get this out of the way for people who are againt the water proof use...i had my purple Xperia Z for 8 months, i wash it every few days with soap and water, i use it ALL the time in the pool and underwater and basically im VERY confident in its waterproof capabilities SO lets stay on topic please.
Thanks for your help and opinions in advance
Sent from my beautiful purple friend Xperia Z.
well i guess it would be ok , isn't it ? it is not like he will do a hypothermic shock like the human body , i guess
yes the phone is waterproof yet it is very easy to crack , my gf droped my phone from like 1m and broke the whole back , happily the camera survived
Well you might end up with a broken back glass if you keep doing it.I havent experienced it firsthand but its easy to imagine...
No brother dont do that.yes our xz can be so hot sometimes just stop for a while if you think your phone is gonna melt.
Sent from my Xperia Yuga
Usually when you put hot glass on cold water the temperature change breaks the glass and our xperia Z is made of glass xD so maybe breaks, maybe not. I'm not sure if the temperature is too hot to create the conditions to break the glass.
according to software : when phone reaches high temp levels , the cpu clock and gpu and brightness level get decreased a little every temp level , so u going to reach a level the phone will start cooling it self as u mentioned , so u don't need to put it in cold water
if u pot hot glass in cold water , the glass will get broken , so careful , don't put your phone in danger just to win couple of mins of cooling
And take in mind the condenced water phenominon when switching in tempetures
Sent from my C6603 using xda app-developers app
I have not taken into consideration the glass.... yes you're right the glass may break if the temperature difference is too big from hot to cold.
Considering i removed the back and front shaterproof films, i dont want the glass to crack! Haha ...saying that though, i must say im VERY confident in the Xperia Z durability as well. I drop it alot and nothing happens beside the corners that got some paint scratches
Remember that the front and back glass is a bit deeper than the frame so even when it falls straight down, the frame absorbs the hit when it touches the ground.
Back to topic...
I had this idea to create water cooling for our Xperia Z but besides putting it inside a clear container (like a cup or a bawl) with cooled water and then use a bluetooth mouse, i dont see how this waterproof advantage can be used for cooling.

Hello everyone, I managed to buy a problematic Xperia Z at a really cheap price, and I sent it in for repair. (The LCD backlight fuse on the motherboard went out)
Well a few weeks later the technician calls me up and tell me that he managed to fix the backlight problem, but now he tells me that the motherboard heats up quite a bit.
Now the thing is that during repair, he managed to lose the metal covering shield that sits over the processor.
Do you think the loss of this small metal cover is the reason why this phone overheats?
Now I haven't actually Used this phone before, so I cant really say how badly this phone overheats, or if this is a regular issue among Xperia Z's.
(I used to have a Nexus 4 before that seriously heated up to maybe above 50-56 degrees when I played any intensive games. I wonder is the xperia Z like that? )
If he does not find that metal covering, do you think I could use some non conductive thermal paste between the Processor of the phone and glass back to dissipate the heat?
I'm going tomorrow to check out the phone.
Any answers would be highly appreciated!

The heat sink is there for a reason and I think it's really important for the XZ, because even with the heat sink the phone can become really hot.
If you could unlock the bootloader, you could down clock+voltage the processor and GPU to prevent it from becoming to hot. I'm not sure if thermal paste will work. It will help for sure, but I'm not sure if the paste will stay at the same spot over time, if it doesn't you'll only be extending the problem.
He could try applying the thermal paste and putting a thin metal plate over the paste. That way the plate can keep the paste together.
