Hey everyone. I'm new to the Nexus 5 community, got my phone a week ago and so far it feels like ive had it for ever. Great device and so worth my limited money.
Anyways. I have been doing these methods on all my phones and so far i haven't seen anyone else trying this.
1. Speed cool your phone
If you have a heat sink from an old pc laying around (unless its one of those huge gaming computer heat sinks) it can now have a purpose again. If your phone gets hot, simply put the heatsink copper side up and put your phone on it. about 2 minutes later your phone should be as cool as it can get without using a freezer.
2. Keep phone cool while wireless charging.
I got a wireless charger recently, and sometimes the phone doesn't get hot at all, and other times it gets VERY hot (about 115 degrees F). So instead of finding the 'perfect' position for my phone to stay cool, i found that using simple cup stands or what ever they are called, helps.
You know those things at restaurants that you put your cup on? those things. For best effect, use 2 or 3 of these, put them under your phone while your phone is on the wireless charger. I think it helps because the cardboard isn't very dense and absorbs and quickly lets off most of the heat and my phone never got over 101 degrees F yet.
3. The first method can also be used while charging your phone though a wire.
Sometimes i want to watch a movie or something while charging my phone on a wire, i simply put it ontop of the heatsink and watch the movie. Might be a bit uncomfortable, so try to found a way for it to be comfortable.
Hope this helps anyone, im still working on a way to make a home made (thin) heat sink for wireless charging.
heat sink testing
So far ive built the heatsink, its about 6 - 7 mm thick using those cardboard cup stand things mentioned above, coper wire, and silicone, and some superglue. i thought tape (specifically the adhesive) would melt under heat.
So far, i have charged my phone all the way up from 20%, temeprature hit 118 degrees F (note this is wireless charging).
Currently testing the heat sink. Charging it up from 85 %. So far at 92% and max temperature is 97F but has gone down to 96F. The heat sink is pretty warm compared to the phone (the phone is actually quite cool).
If you would like to mess around with the design this is how i built it.
Took one cardboard cup plate and put a copper coil on it. I just took about 10 inches of copper wire (thin kind) and made it into a wide coil (ill post pictures later), and then hammered it to be more or less flat. Put small amounts of superglue to hold it in place. Took the second cardboard plate, and put it on top. Used silicone to seal the edge to hold. Also add some super glue to the top of the coil to glue it to the top cardboard piece.
Simply put the heatsink under the phone while wireless charging.
Pictures of heatsink
Here are the pictures.
Ill post screenshots later of the test.
I do the same thing for wireless charging. Instead of making one, I bought a set of ceramic/porcelain/granite (I don't really know) coasters. I used one coaster for wireless charging, and four more under my laptop for when it is on the counter or table (keeps it cool and above any drinks that may spill).

link to the materials? Sounds like good idea.
I have this huge granite/porcelain slab my mom uses to beak bread. i wish it wasn't a 2 foot x 2 foot size, maybe i could have used that instead.
ALSO
so far the temperatures would go up to about 99F and then go back down to around 96...i think what happens is the phone heats up, then the heatsink takes the heat, and cools down while the phone heats up again...cycle

As I mentioned, I am not exactly sure what the material is. My guess is ceramic. I had the idea when I saw them in a store.
You can find them just about anywhere, and decorated any way you like (mine are plain). Link to Amazon
The granite slab you mentioned should work just fine. I never precisely monitored the temperature, but I know its a lot cooler.

Haha like I said that slab is huge for an oven made to bake on. So if I had something to cut me a slice I would.
I was just sitting at my PC and I saw the little cardboard things and though why not try it. I tried with two and it seemed to work okay-ish so like I used my copper heat sink I thought of putting copper in between. Took me 5 minutes to make.
But I'll definitely give the porcelain a try.

I don't recommend putting anything between the phone and the wireless charger, increased distance means less power into the phone and more wasted into the air. Also I don't think the plastic case of the phone will interface well with a metal heatsink but I admire your tenacity.
Maybe log your temps with and without and compare, though you would have to adjust values for ambient room temps otherwise a warmer day could throw off all your results.

Yeah I noticed it takes a bit longer to charge but wireless charging is never actually fast as cord charging. I get about 1% ever minute with screen off and 1% every 2 minutes with screen on.

just out of curiosity, completely. whats the point of this? heat is normal, especially while charging, and does not hurt the device. for the fun of it, i reach cpu temp shutdown purposefully all the time(105C), on all my devices, for years. heat has never ever caused any kind of damage to any of my devices. as the safety temps for battery and cpu shutdown are actually below the temps that our devices can handle before it can cause any damage.

Well looks like I have the exact opposite experience than you. All the phones I've had eventually had degraded battery's because of over heating. I had phones that would last 4 hours on an old battery and 12 on a new one. And that's just from gaming and such. Now charging is pretty much directly heating a battery. Also some people don't like picking up a piece if lava.
If you think its pointless then don't do it.

Battery degradation occurs on all Li-ion batteries. Heat has very little effect on the overall lifespan of the battery. You can expect about a 30% loss in capacity every year no matter your usage patterns.

im not planning on it. as i said the very first thing, out of curiosity.
now degraded batteries that early can happen, but its mostly because of manufacturing defects. the chances of that happening more than once in a row is fairly low. but you said multiple times. which leads me to believe that theres either something wrong with your phone physically, or maybe you are doing something wrong. as i said, on my g1(s), ion, og droid, nexus one, nexus s, galaxy nexus, nexus 4, nexus 7, and nexus 7, ive never had any issues because of heat or because of battery. i do all the testing for trinity kernel, while testing i try to "break" the kernel. part of that testing is keeping the temps right under the thermal shutdown temp for long periods of time. i have yet to see any kind of damage because of this(except for me "breaking" any test kernels).

True that too. But there is enough research to support that heat does slowly degrade the battery.

You can say that again ?
Also...I notice that charging the phone bellow 80% (like even if I start charging at 75%) temps get to about 103° with my heat sink. But when it goes over 80% it starts to cool down. Still doing lots of testing and logging though.

yea, it charges "faster" before 80%, then slows down. then slows down again around 92%. oh, and that article is outdated. our batteries are a newer tech than when that article was written(2010).
Using a Wireless charger doesn't generate that much heat lol.
I don't use my device while charging it either.

My Nexus 7 gets hot!!! Playing none intense games, searching the web, charging and watching a YouTube video. Could this be hurting the device??? It's 86 degrees here where I'm from and 75 in my house. I now charge via Mac because the charger gets so hot!!! Now, I love my Nexus 7 and thank GOD my only issue is a skeptical one. So, I have a iPad 1 2 and 3 the iPad 3 gets kinda hot during intense hourly gameplay and that's it, this seams to not be able to handle the smallest task without getting hot, could it be the plastic back or maybe its okay and I'm just a little uptight about my gadgets???

Making the processor work hard generates heat! This is normal, the longer you do it the hotter it will get. Unlike laptops there is no cooling fan.
Don't worry the processor can still run safely upto temperatures where you couldn't be holding it but that's not likely to happen (unless you're hyper sensitive)
We avg 80°F indoors here. Yesterday was a warm 111°F outside...
Devices can get hot, not normally be big deal. My Rezound gets up around 115°F on a regular basis.

Your probably a little uptight with your toys. When electronics do work that's what happens.
Just like computers if your device is getting to hot it should just shut off

If you're also charging and using the tablet at the same time, it'll also become really hot as well. Source: My Galaxy Nexus, EVO 3D, SGS2 all did the same thing.

my nexus 7 was acting weird and was also getting really hot, my unit was lagging like crazy too, so i returned my unit and now am trying to find 16gb unit somewhere around here.
I have noticed that my replacement Nexus (with no screen lift) doesn't seem to get as hot as my first.
from case?
How many of you that think your N7 is running too hot.....have a case of some sort on it?
Some of the cases look like they would trap heat. I am a little surprised not to see some sort of case like a folio type that has breathing cut out sections to help dissipate heat when using for gaming and other heat producing use types.

I've been using mine for the last hour plus, and I wouldn't even say that it is warm, let alone hot.
Only intense gaming would make it warmer where as for regular use it would run fine. Even when it gets warm it doesn't get warm up to worrying degrees / level.

The back left of mine gets pretty warm. Worryingly so. Just watching YouTube does it.
Don't these things have heat sensors built in that will make the device handle itself if it gets too hot? Usually computer components can get pretty dang hot before having problems, too.
I won't use a case... but if it comes down to it, I might modify one that's open around the area that gets warm.
And using ANYTHING other than the Nexus 7 charger will take forever. You're lucky to get .5amp out of a Mac socket whereas the factory charger is 2amp.
Or maybe these things were built for the winter and not the summer. It does not feel good in the hand because the heat from normal task makes my hands sweat. Maybe it's because it's so slim and the chip inside is so powerful? Still, I don't like it.

Heat is a subjective thing... it was 94° here in western NY yesterday and I was showing off the Tegra 3 by playing Dark Meadow: The Pact. The back was a little warm, but nothing I would consider uncomfortable.

I'm starting to think it's because of the plastic back cover. See, if it was metal then the aluminum would play as a heat sink, but for 200$ I guess this is what you get?

Your phone has a quad core processor and brilliant screen inside of an all metal body. Of course its going to get hot. Other phones(my old gs3 for example ) get just as hot. You just don't notice it due to the plastic body.

Metal is a better conductor of heat than most other phones (various types of glass and plastics). It will feel warmer, even at the same temperature.
The plus side of it feeling warmer is that, ironically, the internals should be cooler, all things equal.
Well does your pc get hot while gaming ? Does the Xbox or ps3 yup so safe to assume heavy gpu tasked games will make it hot . Try to not be charging at the same time . Remember no removal of the battery so when it gets to hot we have little recourse to cool the AC works though lol
HTC-DNA,HTC-ONE,s3x2,s4-i9500
I've never had a metal phone before. Didn't even occur to me the frame would be the heatsink as well. I can breathe easier now thanks

I'm betting you all have experienced this, but I find it ridiculous. If I play a game (not a specifically cpu-intensive game) for say 20 minutes to half an hour, then my phone is so hot that I find it uncomfortable to hold. It does not have specifically warm insides, which must then sound like the metal is doing what it should and lead the heat elsewhere but it's uncomfortable.
If I play for approx. half an hour, it's already way past warm. Warm would feel cold in comparison to how hot it can be. Are everyone experiencing this or is it possible I have gotten a lemon?
It's normal. It has an aluminum back. You're gonna feel some heat.

Aluminum transfers heat differently than plastic. It's gonna get hotter than plastic will. It's just how the metal is.

You need to tell us what temps your phone is hitting. We can't really help you out without that. Maybe your phone is getting hotter than a normal One, or maybe your hands are more sensitive to heat than the average user. Can't know without temps.
For example, my phone maxes out at 42/43 degrees battery temp. It's definitely warm, but not uncomfortalble to hold. Other users have said their phone temp is around this as well when playing intensive games.
If your phone gets much hotter than this, I would return it. If it doesn't, and your hands are more sensitive than ours, I would buy a case/different case and try to live with it.

The phone definitely transfers heat very well, so it seems much hotter than other phones. I don't like it either. I was in Shanghai on the weekend and this phone was making my hands sweat. I think the next big improvements we'll see with phones will be temperature and battery life. It must... These phones are becoming heaters.
Since your phone's temperature is normal, I can only suggest three things. Get a different case, root and try the elemental kernel, or undervolt your processor. Not much beyond that.

I've got two Galaxy S4's and a HTC One they all get very hot after 20 mins seems the S600 has pour thermal profile when it hits the top of it's clock speed. I would say the HTC is just a little bit hotter than the S4 most likely due to the Aluminium. Try a Flexishield case works for me to make it a bit more comfortable.

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.

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.

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.

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.

you look familiar to me, where have i seen you..
Waiting for you to post the solution on how to use the volume buttons on the side of the phone.
What do you expect with no laptop class ventilation?

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.

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.

and im out of thanks, but thanks
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.
Mine gets hot often and sometimes I put it in the freezer for a minute and temp drops back down.
Just now, my phone got really hot, just from charging, so I put it in the freezer for about 30 seconds and it dropped 9 degrees and cooled down.

Wow. Putting it in the freezer will obviously cool it down, but will probably damage it eventually. The real question is why does your phone heat up so much? My S4 used to heat up much more than this and I never had to put it in the freezer :-/
There's of course a difference between heating and overheating -- I assume the phone will shut down to prevent damage in the latter case. My erstwhile iPhone 5 did that sometimes when it was in my car mount and exposed to sun.
TL;DR: You shouldn't have to put the phone in the freezer. Ever.

How hot is "really hot"? The casing acts as a heat sink, so it's quite normal to get hot. I believe the HTC max safe temperature is 55 degrees Celsius.
And personally, I wouldn't put it in a freezer to cool down, going from hot to cold in such a fast time isn't really good on the hardware.
Do you put your laptop or PC in the freezer too? they get much hotter than phones
I rarely got mine hot TBH - mostly when playing Dungeon Hunter 4 for 30+ minutes
But put in the freezer? Nope.
Wont a hot phone quickly cooled cause condensation problems, and eventually water damage.

Quite likely.
LOL this is funny. reminds me of the old days when we would put NES games in the freezer to make them last longer when playing.
I put my phone in the freezer, wrapped in plastic while running antutu, and got the lowest temps and highest scores I have ever seen..

Too funny... :laugh: I would recommend against putting your phone or any electronic device in the freezer because the sudden temperature shock will definitely stress the various components causing the life of the phone to decrease. Just let the phone cool down at room temperature.
The quick temperature change could crack the glass so I would stop.

LOL I do the same with food that's too hott. Wouldn't say I'd do it with my phone though. Just leave it alone for 10-15 minutes and it should cool back down fine.

Digging up an old post I ran across. Browsing the web for random input...
This guy who "proved nothing" shed a little insight into answering the OP's question.
The answer: Know what you're getting into. If you have to ask, then highly consider not doing it. If you feel confident, try it at your own risk. That said, experiementing with devices growing up, I've put a lot of stuff "on ice" (not directly of course), but again, know your hardware down to the very solder that connects it, then you'll be less likely to fug up your project. :fingers-crossed:
(plastic bag + water resistant phone... overkill, but hey, I've seen these things frozen with liquid nitrogen and come back to boot) :victory::highfive:
I've put my M7 in the freezer many times. I just throw it directly in the ice tray for about 5 minutes. The first time I got worried because it was on, and when I took it out it had frost all over it but it still works.
