    I know that a few people have had this problem before but did anyone find out the root cause of why some phones just cannot function in the cold?

    it is now hitting sub zero in the mornings in the UK and it has effectively rendered my iPhone 6s useless. taking it out of my pocket on full charge will mean it will switch off within minutes and complain that it is out of charge.

    A google search reveals that quite a few people had this problem but I can see no root cause.

    Ummm simple, Lithium batteries simply do not function at low temperatures. It's only temporary once it warms up it can start to function again.

    Google for sure mentions that L-Ion batteries do not do well at very low temps.

    Keep it in a pocket against your body and when using it, make it short or it will get to cold to operate.

    It is all about physics. Also your battery is likely getting a little bit on the worn side so that makes it even worst.

    Out of curiosity, can you try enabling the low power mode before you go outside and see what happens?

    I am experiencing random shutdowns of my 6s, nothing to do with cold (yet). Researching on this topic made me think some 6s might be defective / might fail in some way related to battery or battery readings. Enabling the low power mode seems to help, I'm curious to see if it would help in your case.

    By the way, disregard what the previous two guys said. They mentioned physics of the accumulators but forgot one of the most important thing about physics - regimes of applicability.

    My understanding is you're just trying to ocassionally use your phone outside in slightly chilly weather. I read Russian and I've never seen people discussing shutdowns as you describe as normal. If anything, in Russian winter frozen fingers may cease being recognized by touchscreens and I read about people being cunning and answering phone calls with their noses. Still no shutdowns were mentioned.

    I see other people using them all the time with no issues. I also surprisingly have a number of friends with various iPhones and none of them have had this issue - or at least not to the extent that my phone has.

    Back in the good old days of Apple (i.e. > 3 years ago) I would have simply made a Genius bar appointment and got the phone swapped out but even though Apple got rid of John Browett quite quickly, he appears to have been there long enough to turn the Apple customer service into something approaching Dixons.

    Apologies to all. Despite doing a search I completely missed the other thread that covers this subject.
