Cold weather and your phone.

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.

Please help me solve this once and for all....

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.

Heat

Some phones are great to take camping because if you play Asphalt 8 long enough, the back warms up to the ideal temperature that can bake bread. Rate this thread to express the extent to which the Huawei P8lite stays cool under extended heavy use. A higher rating indicates that even when playing strenuous games for long periods of time, the phone doesn't get uncomfortably warm.
Then, drop a comment if you have anything to add!

Oh boy, I can cook eggs on mine phone

True. This phone gets really hot in gaming. Try charging and gaming at the same time and, believe me, you will be able to fry potatoes as well!

yep. By default he heats a bit, that is way he doens´t have full potencial unlocked, like gpu that can goes to 700mhz but is locked to 500mhz... They build a preatty phone so doesn´t have much heat dissipation :\ ...

Big feature

My phone at start stayed pretty warm while even playing games/watching youtube + charging. But after a time when I swapped the original charger with a 2A one to "charge faster" (stupid me, I should've read what happens when you don't use the original charger) started to heat. But that might also from when I dropped it in water. I don't understand. On some roms it burns hot on some roms it just stays warm every time.
Also(stupid me chapter 2), I made a mod to this device. I dissasembled the phone completely and removed the metal shields. Added a thin layer of thermal paste on all of them, (well, except the wifi , ril chips) and put the metal shield back. Now it heats even more on the roms where it burns hot because the heat travels in the plastic. The plastic has to make his job now in removing the heat.

I don't know what phones are you using, but I use ALE-L21 latest version with tweaks, and hard modifications, and I don't feel that the phone is even hot while playing hard games (not asphalt, that's not using all the potentional...i'M talking about gta sa, mlbb, rr3,assasins creed identity etc) and it's not hot. I would use max OC at GPU/CPU and play like that, only to feel that the phone is warm. I bought the phone lately, and I guess it was somehow special, or latest "review" of the phone, cuz I never had any problems with it, like others with wifi, bt etc...Battery is still awesome after killing it with gaming/charging.

mine only heat much if i charge it while using or if it has casing protector and im using it while its charging

So many heat, every day I bring poop out of my device, it sometimes generates so much heat my hands in winter won't get cold! And After playing Some Online games with Mobile data on, Phone can reach 58 degrees cool huh?

Low temperature shutdown issues

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
https://www.google.com/amp/s/amp.usatoday.com/amp/860460001

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.

Question Which battery temperature is normal?

My phone happens to stay around 37-43 degrees even if i am not doing anything. This makes it uncomfortable to hold in my hand. I am using the default case between.
Does anyone else have this issue?
Note: It´s currently 25 degrees here in germany and my phone is not cooling down at all, staying at 39 degrees while all apps are closed and I am not charging.

Pretty normal. Mine is between 31 and 40 degrees - depends what is the room temp of course and what im doing. Snap 888 is a hot processor .
Currently it has 32 degrees - phone is cool.
Btw. The temps improved a lot on A.19 and A.20 version. On A.15 and A.16 my phone was getting hot easily.

I live in the desert... I know a lot about heat and fried electronics
It's running hot because of services running in the background. It's in the 90's (°F) here and my 10+ is running at 97F; a couple degrees F above ambient. If it was running like the OP's I would need to turn it off or cool it! Not acceptable.
Google Backup Transport, Framework, Firebase, Google play Services and all cloud apps are prime suspects.
Trashware like FB, WhatsApp etc.
Hunt down the perpetrators and deal with them directly.
Power management can also cause excessive battery usage by interfering with needed dependencies. Turn off all power management and go from there.
Clear system cache.
Try a network reset.
Disable wifi unless you need it.
Cool or stop using phone once it reaches 100°F*.
*37.7778°C
The Fahrenheit scale is geared much better to real life usage than the Celsius system. It's range is scaled better for the temperature you live in.
43°C or 109.4°F is too hot. Max is 103°F for me and then I shut it down.
Don't expect auto thermal shutdown to save your device! The temp can rise faster than the sensors can detect it in critical areas like the AMOLED display with it's millions of temperature sensitive semiconductor junctions... and little heat sinking capacity. It's also helping to sink heat from the mobo and battery. Worse, glass is an effective insulator but you can feel how warm the display gets as it helps to sink the heat.
A case can also contribute to the problem. Some cases sink the rear cover heat better. I'm not advocating running the phone bare though as one drop is all it takes. Just be aware of this.
Using a damp microfiber cloth to cool it works well. I wrap one around the whole phone when charging.
Even now it will keep it way below 100F when fast charging.
Airflow should also be used... got a fan on me and the phone this minute.

How do you guys measure the temperature? Built-in menu or an app?

Mostly the temperature should be around the range of 40 to 45 degrees.

I watch the battery temp in Accubattery.
At 103F it's turn off time, regardless.
