    i have to leave my phone in my car when i go to work because my job doesnt allow phones to be brought to work. I have to go through a metal detector so sneaking it in isnt an option.

    i leave it in my car for about 7 hours and the temperature gets to around 30 F is there anything i can do to keep it warm in my car? possibly something i can wrap around it or place it into. also leaving it at home isnt an option.

    30F temps are not going to hurt your phone so I wouldn't worry about :D

    You will be fine. Just power the phone completely off when it sits in your car, especially since you are not using it. They ship those phones in colder temperatures.

    I've read that Neoprene is a good insulator. I've read an article that recommended leaving your iPad in a sleeve or soft case made of Neoprene if you have to leave it in a hot vehicle for an extended period of time. I would assume that it would also be useful for a cold vehicle as well.

    Based on the situation you described, I think I would opt for a second phone. I think I might even go the route of a prepaid phone rather than repeatedly leaving my iPhone in a cold or hot car.

    I think the best route would be to get a second phone which is a prepaid phone, but on the same carrier and just forward your iPhone line to it.

    Both my work phone and my personal phone are on AT&T. So I keep my personal phone forwarded to my work phone most of the time.

    Because mobile to mobile minutes are free, my employer does not incurr any cost when someone calls me on my personal cell phone.

    Edit: A quick look at Apple's Web site shows the following temperature ranges for the iPhone 5:

    Operating ambient temperature: 32° to 95° F
    Nonoperating temperature: −4° to 113° F

    So like the other callers suggest, you are probably fine leaving your phone in your car in 30 degree weather. However, I still think I would opt for a second, prepaid phone if this is something I had to do on a continous basis.

    You could also try leaving it in a box or cooler with one of those instant heat packs that are used for muscle aches, although this probably wouldn't be economically feasible over the long-term unless you find a re-heatable one.

    Again, just leave it off. Directly from Apple site

    Operating ambient temperature: 32° to 95° F (0° to 35° C)
    Nonoperating temperature: −4° to 113° F (−20° to 45° C)
    Relative humidity: 5% to 95% noncondensing
    Maximum operating altitude: 10,000 feet (3000 m)

    Thanks guys. I wanna look into that neoprene sleeve thing and I think I'm just gonna turn it off when I go to work from no on so it's not on while its cold. I live in jersey so it's gonna keep getting colder. If anyone has anymore suggestions I would appreciate it btw it's an iPhone 5

    I've been using my 4S on a daily basis in ~25-30 weather and haven't had any problems so far. Is this going to create problems for me in the future?

    No. Just won't get as good of battery life in cold weather.

    Likely not, and if your phone is in use, odds are it's above ambient temperatures anyway. Still, I'd keep it in a pocket when possible.

    I keep mine on my belt in much colder temps then that since I work outside quite often. I use a life proof case and holster is its pretty much out in the open.

    Come summer time, it might be best just to leave it home.

    Just leave it in a cooler. Should stay several degrees warmer than the outside environment.

    Why leave it turned on? The inside of the car in daylight will be warmer than the outside temp. No problem.

    I'd be worried about summer. The car will get broiling hot inside.....

    But you've been given the temps as provided by Apple so I'm not sure what the issue is. It sounds like the phone will be fine. Or if you're truly worried, get a dumb phone for the car.

    no issue anymore I turned it off when I went to work and put it in my pocket for 10 min when I got out to warm it up a bit and it worked fine

    Small cooler as others have suggested will work just fine. If that's not good enough, search for a solar powered cooler. Make sure it's fully charged before getting to work and you'll be nice and cozy in your office as your phone's temperature is comfortably sitting in the vehicle under a satisfactory temperature.

    You really have a couple of options that you can use separately or together:

    - A heat source
    - An insulated container

    That's really it. There are all sorts of variations of the two to choose from. Shut it off and it will be find down to the minimum nonoperating temp posted above.

    I used to leave my iPod Touch in my car since I typically listen to that on the car ride into work. I would definitely recommend you turn your phone off to conserve battery power. For the most part when I left my iPod in my car in the winter and summer, it was fine (I normally keep it in the glove compartment).

    keep Siri warm

    Even if it may feel like it, your phone is not a real person.
    It will not catch a cold or freeze to death in cold weather.

    It is just a piece of electronic equipment......,
    but if Siri starts sneezing, it may be a distraction while driving

    I would get a case for it and wrap it up in a blanket in the trunk. When I have had to leave my computer or iPad in my car during cold days I always put it in the trunk because it seems to hold even more than the interior of the car. On hot days I would sometimes put whatever it was in a freezer bag. I didn't freeze the bag, just normal and figured it would maintain the best temperature there. I have never had a problem.

    Put it in a little sandwich container lines with polystyrene :)
