> But I have not had a battery completely stop working in the winter, ever. My car battery continues to work just fine. My camera works just fine, so does my laptop, so does my smartwatch, so does my TV remote, so does my powerdrill, so does my radio, so does my torch, so does the wall clock. But who knows, maybe I've just been lucky all these years. And BTW I'm not talking about some crazy Siberia winter. I'm talking about 30-40F here!

Weird, my history with car batteries suggests that they do, in fact, completely shut down in cold winters. They do it with such regularity that many people carry specialized equipment in their cars to deal with this eventuality, and roadside-assistance crews regularly deal with it as well.

I happen to have had my camera battery drain completely within minutes of full charge when used outdoors in mid-winter, but I don't often take my DSLR outside in mid-winter any more since my phone fills that need.

I don't usually take my tv remote, power drill, or wall clock outside in mid-winter, but your mileage may vary.

Apple doesn't have access to a different set of physical laws than other companies. Physics is physics, and those batteries don't deal well with cold, period.
