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.
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.
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.

Also I think its worth a try, maybe someone can come up with something more effective.

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.
I have read that high temps are bad for a battery, and the past few days ive started to use the Standard Moto x4 quickcharger more often.
To compensate the rise in temperature, i just lay the phone on a cold stone floor with the back on the bottom while charging in short bursts of 25%.
I notice the cold floor absorbs the heat, and the battery stays cool that way.
Would charging in this manner be harmful for the battery, or is it a succesful way to minimize battery degradation through quickcharge?
I check the temperature with accubattery app after quickcharging for lets say 25%, and it always tells me around 25°C max (77°Fah)
The floor is probably between 5°C (41°Fah) and 12°C (54°Fah)
I noticed that when I was outside today (pretty cold 3°C) , accubattery showed battery temperature of phone was 12°C;
so the temperature reading in AccuBattery is probably accurate.
This means it's not harmful to quickcharge my phone @ a battery temperature of 25°C or less., by laying the glass back on the floor.
It probably helps to neutralize some of the negative effects quickcharging has on the battery
[/nerdmodus]
I really don't think that quickcharging has any harmful effects; for sure it has been designed taking also thermal conditions into account.
I can't imagine I'd have to look for cold stone floor every time I need to recharge my phone
Is this thread for real?
Lmfao. Life's too short to be worrying this much about a phone battery. Just charge the damn thing.

Glad you got a laugh out of it.
For you then,
when quickcharging Just don't put your phone on a cold surface, let the battery get hot...
let it go to 0% and then charge overnight to 100%... everyday
and keep it laying in the sun from time to time,
all these things are bad for the battery but apparently they make you enjoy life more.
so enjoy :silly:
Does it has a heating issue.
My black phone always feels a bit hot. But the performance doesn't drop. I think because of the glass back I can fell the heat. Because I checked the cpu temperature it was about 37-40. And my room temperature wat around 35+.
And another thing is that the charging time is a bit slow considering it's 5020mah and 33watt fast charger. It takes around 1 hour from 15% to 80%
This morning I charged from 7% to 100% in just over one hour no problem there.
I have the orange gradient design and only feel it getting warm during charging.

A good news my brothers the heating issue i told is gone. After miui 12.0.10 update.
