Just recently moved to Chicago. I work out side quite a bit, and will be in the winter. Normally I keep my phone in my inside jacket pocket when I lived in Atlanta, No where near as cold there. Was just wondering what do you all recommend? Keep phone inside somewhere or do you think between my body warmth and the jacket, it would be fine. Not sure temp would start to damage the phone. I know when I came up here for New Years my old tour(9630) in just my pants pocket started to freak out.
Thanks for your time.

what u need is a hiking backpack, a generator, and a toaster to put ur phone in
Phone temp. doesn't affect much depending on how low of temperatures we are talking. anything lower than 0C (30F) I would get worried about. At lower temperatures issues with battery and LCD's happen. So I think as long as you keep it in your jacket close to your body heat it should be fine.
Yeah, in your inside pocket just body warmth will keep it safe. The only things I have noticed with cold phones is batteries discharge faster and lcds will stop responding. I have had a few phones freeze inside my truck when I leave them inside when I was hunting, but besides probably killing the batteries faster than usual I have not had any serious problems. Just warm them up before you turn them back on!
Lol @ hiking and toaster. As far as how low for temps I wouldn't think anything below 0 but then again this will bemy first winter up here working. Its not like I plan on being in the cold long. But you never know. Thanks for the quick replies. =)

I used my g1 in temps ranging from 110 to -10 (farenheit) with only minor issues. At warmer temps the battery seemed to discharge faster and below 20 the screen wasn't very responsive. As stated above, just keep it in an inner pocket when cold.
Welcome to Chi town. Enjoy your stay and the crappy politics. 30 degrees or below for more than an hour it goes in the inside pocket or I will stash it somewhere inside a building till I am done working outside.
good day.
Cold temperature couldn't cause serious damage to phone, only that it could sluggish, or make a fully charged one turns to low battery. You might encounter some screen problems but nothing a warm room couldn't fix. Definitely, your cellphone can surely survive a day on the slopes without worry.
So, it seems we've hit the barrier
Nexus S runs stable @ 1300 Mhz (1.3 Ghz)
unfortunately prolong use of this speed raised the CPU/Battery temperature to over 60c +
that's a bit too high for comfort
the number might be small
but actual usage performance is blasting fast
a full system restore (330+ apps) using TitaniumBackup took roughly 10 minutes @ 1300 Mhz
the same full system restore at stock 1000 Mhz it took twice as long for TitaniumBackup to complete the restore
so, now the real challenge is to find some one that can provide us some water cooling kits to install into our phones, so that we can clock the crap out of it without it overheating to death

Now that I would like to see! but it would make the phone uncomfortably bulky I fear nano-technology water cooling? Anything's possible right
Edit: those are nice times though! Considering it's not even double the 1ghz, but it chops times in half... I might give some overclocking a shot now!
Honestly im surprised we havent seen any time of cooling built into say the phones back cover as a heat sink.
Maybe in the future. but as it gets smaller the power draw gets smaller and the heat generated drops.
so who knows. its just exponential

I think power is one thing but with the poor battery life our phones have, chewing battery amps as heat is a waste generally. Energy efficiency is what they are trying to achieve, not a pocket warmer Not that i'm against overclocking though.
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.
my phone gets really heated up even with normal usage, i.e., even if i just turn on the screen and look at settings menu or view photos etc, it reaches till 32 degrees, and if i turn on a game like riptide2, it reaches till 36 degrees very fast. same with charging,even in idle charging mode it reaches 36 degrees.
while idle, screen off it remains between 29 to 31 degrees
i checked with OS monitor, there is no rouge app eating up resources that ll heat up the mobile
Please help, if this remains the case my battery will wither away fast

In case you haven't notice, this is a water and dust proof phone with IP58 rating.
So expect a little heating from its tight protection where water can hardly get in.
As long as it didn't get too hot and make you uncomfortable, I think that's pretty okay from a user point of view.

thats true but when it gets beyond 34 degrees it gets uncomfortable , specially if ur on a call
wat i really wanted to ask is if this is normal and all u get the same temperatures, else i would return the phone for a replacement
Can't tell that is normal or not cause I've only one NTT ZR, but it do reach almost 40 degrees after running Antutu benchmark three times(take off back cover and uses IR thermometers Aim to the area near main camera).

So far it doesn't get too hot under heavy gaming or prolonged phone call AS LONG AS you are under a good ventilation.
When I was on a trip to a beach under a scorching sun, my camera stops functioning after shooting roughly 10 pictures.
It says "Cannot connect to camera due to high temperature in camera"
So if your phone gets too hot even you're in an air-conditioned room, you might wanna check it out.
It is normal until it gets 38 degree, after 45 degree you might see some malfunctioning on touch that doesn't work correctly, You then should cool your phone down immediately (turning off your phone might needed on some cases!)
Hot
Yep, it often stops the camera when it gets hot. Of course it happened more often in the summer. (folks down under: I know your summer is just about coming )
There is process running in the background Overheating monitor (or whatever) that is called. I do not recommend stopping that as you may burn your CPU or so.
By the way, do you guys then say the cover with the rubber seal is just the top of the crop, and due to the compact design, it sort of resist water in general, anyway? In summer it happened that a couple of drops of water got under the back cover. I was a bit worried.
Of course the usb charger slot cover does not seal that well as on day one - I am getting my dock next week or so.
hey, i've just got my ZR few days ago.
i played 2 straight hours of real racing 3 today. drained the battery empty from 60% charge, either way, the device was defenetly not cold, but it didn't overheat.
i was comtrable holding it and i got no notifications about over heating, more over i paused the game at one point to take a picture of my cat who came bugging around, the camera worked just fine when it was hot.
i live in israel, ain't excatly the coldest country in the world...

Nice cat, but clean his eyes, dude!
Don't worry about the heating problem I watched videos where the sony Z (which is quite similar to our device) gets to a 47 degrees Celsius and then it stops heating, the processor downclocks and everything is fine. If you think that this is heat check what the LG Optimus GJ does, you can practically light a fire with it . All of this is due to the fact that it's sealed and can't cool down like other devices. Samsung Galaxy s4 also has these problems and lots of other devices too. Here is a video of the Z (it's in russian but you'll understand from the temperatures) that can show you how it compares to other devices (as I said our device uses the same chip so the results are similar) it also shows the battery performance.
Hi
I am into hill walking and mountaineering. I am finding that my note 8 will shutdown if the temperature is below about -5C and I start the camera to take some pics. Once it's shutdown, it will refuse to start until warmed up, and needs a soft reset. It also comes back with 5% showing in the battery but had 80% at the time of shutdown.
It's rather a pain in the neck. My old Xperia Z5, Z3C and Z1 would do -20C without ever having issues.
I am assuming this is just an annoying 'feature' of Samsung devices rather than a fault.
I am thinking of running a background number crunching app to prevent deep sleep! Samsung is not interested, wondered if others had the same issue. If I stick my old Z5 and the Note 8 in my freezer at -15 for an hour the note 8 shuts down, but the Z5 carries on as normal. Prob down to cheap/nasty battery tech in the note 8.

That is interesting. I'm going to northern Japan this Sunday for 3 weeks. It will be snow and freezing cold. I'll report back how my Note 8 works there. I really hope mine won't shutdown when i really need to use it.

That's a lil concerning -5C = +23F. Last week it was negative -10F here. I was shoveling snow for about an hour, big driveway/sidewalk path aka snowblower needs fixed. I took a few pics and took some calls/text. No shutdowns here. Now at the same time shoveling snow takes a lot of work so maybe my body heat was keeping it warm in pocket.
But at the same time the same could be said about what your doing and body heat idk. We need more people to chime in.
Oh bonus people in hot climates don't be afraid to chime in. Curious how this phone handles the heat. Gets cold here in winter, but really hot and mushy in the summer.
Hi
Mine is not in a pocket, but rather mounted to a chest strap on rucksack so it gets full force of cold and wind - exactly the same as my old Z5 - reason: it is also my GPS for walking and ski-touring. Maybe you can leave yours out in the cold exposed for an hour, then try taking a photo and see if it shuts down?

You could put it in a crown royal bag with a handwarmer. Would probably keep it warm enough. I live just 80 miles south of Canada in the PNW. It was 7 degrees last week. I left my phone in my car for a while and it was fine. It was really cold, but still working.
it's a glass phone. there is nothing under the glass but the components. that's the difference between it and your sony phone. glass is not a great insulator
Aye, might offer a work-around but not a particularly convenient one. I'll be back with Xperia end 2018 when I am due an upgrade. The phone only appears to actually shutdown when the camera is started while its cold. Must be high current draw, causing a voltage drop that gets detected and the device gets shutdown. Love the screen and pen, and camera, moved from Xperia after three separate devices as they looked old fashioned with their HUGE bezels, and refusal to adopt wireless charging.
It was 2 degrees F here in Nashville TN last week, but I stayed indoors and didn't go outside for any length of time to see how my phone would have been affected. Had some friends who went to the Jacksonville/Tennessee football game a couple of weeks ago.........16 degrees; they left early because they couldn't feel their limbs even with multiple hand/foot warmers...............I wonder how they kept their phones warm.

it's a glass phone. there is nothing under the glass but the components. that's the difference between it and your sony phone. glass is not a great insulator

Its a glass phone in a heavy duty rubber case that I stuck it in! Both phones have a glass front! The wee bit of alu on the rear of the Z5 vs the glass on the Note 8 should not equate to a 15C difference in the temperature the device can withstand while continuing to function. I suspect the real reason is inferior battery tech vs Sony, and over-zealous low voltage detection and device shutdown.
I note that my Samsung 360cam also shutdown due to the cold this weekend gone, but my GoPro kept working.

this could be a result of sammy overcompensating for their note7 debacle last year. the fact that root limits my battery at 80% says a lot.

Isn't that 80% thing due to locked bootloader on Snapdragon? Root on Exynos doesn't have 80% issue, so not sure it's related to those Note 7 problems. The camera issue itself might still be though.

you're right, it is due to locked bootloader and the detection of root. it is no mistake that 80% is the cap when rooted. samsung did that on purpose. it started on models released after the note7, which is why i suspect they are weary of battery troubles, and if you root and begin to alter the system, the chances of an incident go up.
what camera issue are you referring to?

Hi
Mine is not in a pocket, but rather mounted to a chest strap on rucksack so it gets full force of cold and wind - exactly the same as my old Z5 - reason: it is also my GPS for walking and ski-touring. Maybe you can leave yours out in the cold exposed for an hour, then try taking a photo and see if it shuts down?

I will do that for you. I have a porch on my 2nd floor room. We're supposed to get 6-9 inches again this weekend with below temps close to 0 F maybe below. I will leave it out for an hour then try to use it. Probably will have same problem as you I am guessing.
Especially when phone is exposed like you pointed out and no body heat to keep it warm. Like others pointed out which forgot glass sucks for insulation. But at the same time I thought the note had a few layers of glass? The best house windows are double and tripled layers sumtimes more. They offer good insulation.

Great, thank you for confirming. The camera issue was the one mentioned by OP regarding trouble in colder temperatures. I just meant that while the 80% battery limit wasn't related to battery concerns or safety measures, I can't say with the same certainty that the camera issue described by OP isn't somehow related to that.

Maybe triple pane windows are made from a special type of glass? Or perhaps the spacing between those layers provides insulation not present on our phones? Not sure, just speculating here...

Yeah idk crap a bout house windows lol. You're right they're made out of special glass I believe and spacing exists. Would think even few layers of glass would make some difference in phone? But I am no expert on glass and insulation. So I will just shut up lol.
glass,plastic,metal or whatever material wont do any difference in cold weather with prolonged exposer.( case or no case)
if it takes 10 minutes to get to minus 5 or if it take 30 minutes, you still will get there. the question at hand is at what temp does the phone stop( if it acctualy does).
i think this is the data we are looking for.
Little more insight

It happed recently two times with my S9 Plus at around 0C temperature both time battery was above 50% and after restart it was at 2 percent. i don't know why the this happened at this "happy to work" temprature.
