iPhone from 6 and up are notoriously bad at cold weather. Previously people talked about reduced battery life in cold weather, but it was never really a big problem (I guess the batteries were thicker). But with the iphone it drops from 80% to 5% then dies in a matter of minutes. People I know have been talking about it and I dont go out on a cold day with the battery at less than 50%. Which was never the case before, even with iphone 5.

Edit: now we are talking temperatures below -10c
