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.

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.
My phone gets pretty hot when gaming. Does this happen to anyone else?
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

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.

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).

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.
I'm going to put short sentences for quickness
Bought N6 off Mobile Phones Direct. Good service. No issues.
Phone charger starts whittling.
Motorola replace charger.
Phone slowly develops symptoms of dodgy battery within 6 weeks:
Expanding battery, case pulling away, red hot charging and draining fast.
After lots of liaison with Motorola who did their best to suggest it was my apo usage they eventually take it for repair. I sent it off ' immaculate ' apart from the fault.
Despite me sending loads of documented online proof that devices like this are being replaced, the Phone comes back 'repaired' not replaced which disappointed me.
Any way I get it back a week later, and initially the phone seems better; apparently it's had a new back and battery.
However I noticed the back was not flush. About .5mm out in alignment and its slightly raised.
In addition, the phone battery gets up to 40 odd degrees when charging and at times it's not pleasant to touch, it's that hot when charging. This is how it all started in the first place!
They've offfered to take it back 'again' and do a ' sort this once and for all ' repair.
I just feel hard done by here. The phone was brand spankers in April and 3 months down the line it's in for a second repair and Motorola aren't even considering replacing this obviously dodgy handset.
If this second repair isn't perfect and working satisfactorily, surely I have some sort of legal rights here to demand a replacement under the not fit for purpose sales of goods act ?

40C, you do realize that a human body on average is at 37C?? 40C isnt even close to being considered hot. when charging, 40C can be considered cool, not hot. lol.
Yeh I realise this I'm just saying that the CPU temp app suggests that temp, but to touch the phone is red hot. Like a cup of tea after its been sat for 10 mins Max.
Thanks for the condescending tone though.
Red Hot suggests burning your skin off. Red Hot would melt the device.
The device is going to get somewhat hot. Not red hot as you suggest.
If that were the case, you would easily be able to separate the glass from the LCD and also pull the LCD from the frame.

unfortunately, feel isnt an accurate way to discuss temperature. all feel does is show you whats warmer or cooler than what you are feeling with. and that has nothing to do with my tone towards your issie, it just is what it is. i read people complaining constantly that their phone reaches 40C(lol). well, guess what, it can get much hotter normally, up to 100C, thats 212F, or the boiling point of water.
i feel bad for you about your issue, but that happens. but 40C when charging has nothing to do with it.
I'd send it back for the second look-see, since you feel that the back is out of alignment (picture, please?)
I'd offer that the heat issue doesn't seem extreme for a phone, depending upon how it's being charged (e.g., fast charge). Also, do you keep this in any sort of case, perhaps?
I've actually never used the Motorola charger, instead I use a USB 99% of the time. I do recall reading about battery issues with a minority of folks who used the fast charger, so perhaps that's what you initially hit?
- ooofest
For starters the app might be inaccurate but all I know is the phone to touch is considerably hot. Heat kills battery life or increases degradation so therefore it won't be long at this rate, before I need another new battery. My point is this is how it all started and its starting again. Motorola seem quite happy to keep repairing. My simple question was where you feel I stand before claiming unfit for purpose. In a 2 year contract I expect the phone to be reliable but i have no trust in this device. I'll send it back see what they do. Probably another case and send it back.

and unfortunately, touch does not give you a temperature reading. ok, try this experiment, itll show you about touch and temperature. get 3 glasses of water, one cold, one hot, and one room temperature. put your left hand in tbe cold water and your right hnd in the hot water. keep them there for about 3 minutes. then take out both hands and put both hands into the room temp water. your left hand, which was in cold water, will now feel warm. and your right hand, which was in hot water, will now feel cool. yet they both are in the same temp water.
anyways, send it back, and a hope for a better future from me to you
Right.....Thanks for that. However I know the difference from a phone thats warm to touch and overheating. I expect warm, but I know the phone should be getting this hot, end of. I'm not the only one as well with this issue... Just do a google search. See for yourself. Clearly im pissin in the wind here.

battery bloating, no you weren't the only one. with a heat issue, you are. sure, you can google and find people that think they have heat issues with the device, but in reality, the issue is in their heads.
Like you said pissing in the wind. Good luck getting help just ridiculed
Mobile Phone Direct in the end replaced - as I was told it fell to the retailer regardless of 28 days or not, if its within 6 months in the UK it falls to the retailer in cases like mine with faulty products. In the end, after sending the phone off to the retailer, they replaced it with a new one one, no issues - took long to get there, but I did in the end.
The new one was perfect throughout my contract. Not a single overheating issue - although it did get warm when charging (nothing like before) and the battery and back cover remain fine.
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.
Nigel
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.

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?

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.
