iphone 6s dies below 32F with battery charged more than 50%

It's crazy but my iphone 6s also my wife's iphone 6s plus are die at temperatures below 32F with battery charged even 70%!! It takes 3-5 minutes to shut off. The temperatures are not critical here in winter 25..30F, but I can't use my phone!! I have original ipad mini installed in my car and it works great even at 20F and below without any problems! Also I have no problems with my previous iphone 4, 4s, 5s, 6 - all of them have no such problems!! Maybe I have a defective battery?

How's yours?

I snowshoe for exercise every morning and have used the current iPhone since the first version. The iPhone 6s is by far the most sensitive to cold. The 5 was also sensitive but not nearly as much as the 6s. I must keep my iPhone inside my top layer (fleece) or it shuts down. It acts like the battery is dead but will turn back on after it warms up a bit. It only takes about 5 min in very cold temp to have it shut down. I take it out for photos but if I take too long it powers down. Of course it is humid inside my jacket so the lens often fogs up when I take it out for a photo.

My guess is the battery power output goes down dramatically when it reaches a certain temp. It will often shut down when I try to do something the takes more power like post a photo or use PhotoSynth to create a stitched image.

Interestingly, I never had the problem before the 6S. I've had iPhones since the 3GS ... so I guess something has changed, and I'm pretty sure it's not the weather!

Apple went from a plastic case to a metal case. The plastic case provided some insulation, so the normal heat of the battery might keep the phone warm enough under some conditions. Just speculation. But if true, putting a rubber or plastic case on the back of the phone might help also.

I haven't seen any smartphone that has a working temperature range specification different from the iPhone other than industrial or military devices that are much thicker and heavier. The limitation is the battery technology.

Confusing the issue with facts is unlikely to help.

Seems to be the story of our society these days.

I've always used an Otter box ... but the one I used for previous iPhones was rubberized while the newer model is a different material that does seem to retain the cold more. Don't know if there are better, more insulating cases that are just as durable.

Well, yeah, it's physics, but the OP was of the opinion his phone was uniquely under-qualified to work on a snowy mountain top. He should ask the other skiers what they were using make an informed decision as a consumer, or they could have been trying to press buttons to make their phones come on and they weren't working either, we have no way of knowing.
