I live in a country where the temperature drops well below freezing for 3/4 months a year. Many days it drops as low as -30c. Does this affect how my iPhone 4 will operate?

The iPhone 4 indicates an operating temp of 32° to 95° F (0° to 35° C). Your pocket would be significantly warmer than that, so if you want to use your phone outside it would probably be best to keep it in your pocket and use a hands-free device (or headphones).

The iPhone also has a "non-operating temperature" of -4° to 113° F (-20° to 45° C), and you should try to keep it above this temp, even if it's powered off.

Thanks for the reply Eric. You've given me some very useful information. But tell me this, what will happen if indeed the phone is subjected to sub zero temperatures for an extended period of time. My job sometimes has me outside in this weather for up to an hour at a time. Don't get me wrong my clothing is more than capable okeeping me warm but will it be enough to keep the phone in my pocket?? Or will I have to resort to placing it between my butt cheeks?*

My iPhone got confused the other week, I was sitting in my car, outside temperature was -2 and I got a call, then the iPhone said that it overheated :confused:

The temperature here in the UK dropped to -18 Celsius a few times before Christmas and my iPhone was fine. Admittedly, I didn't leave it outside in those temperatures and it was in my pocket most of the time, but I did use it to make calls and had no problems at all

More often than not it will just lose power if it gets below operating temp. If placed in an interior pocket (like a front pocket in a pair of jeans), your body heat should keep it plenty warm.

Sorry to bump an old post.

I've been in Iceland for a week and my iPhone 6S has lagged like crazy when it gets cold to the touch. Didn't expect cold to affect it at all. Rather interesting.
