iPhone 6 battery dies in cold weather

Battery dies on my iPhone 6 in cold weather. Phone is about 15 months old, and dies from good battery 50% to 30% down to nothing and auto switch off. ON normal weather the battery is still very good and doesn't show sign of weakening on any normal day. But if it is cold outside, phone will dye in minutes if used outdoors. I first noticed when we went skiing around -5C (20-25F) and it was really bad there. But now it started doing it when it's around +5C (41F) shutting the phone down from 30% battery. When I plug it in, it immediately turns the phone back on and shows 25 or 35% remaining....

Anyone? Design issue? Specific app to kill? Running iOS 9.3, but it was already doing it on iOS 9.2 .... Thanks

SUCCESS AT LAST!!!. Ok a little over a year ago when the problems started, post iOS9, cold weather and slowing down, I had my battery tested at the Apple Store. It checked out fine, so the tech said to wipe out the phone and reinstall from back up. That sped up the phone but no joy on the cold weather problem. Fast forward and the phone slowed more and more with each iOS update. Anyway, I reset the phone again and then made an appointment at the Apple Store to replace the battery. Well the battery failed and I have now replaced it. THE PHONE IS NOW FASTER AND I JUST TOOK MY DOG FOR A 1/2 HOUR WALK AT -11C OR 12 FAHRENHEIT STARTED WITH 97% MADE A COUPLE OF CALLS AND GOT BACK WITH 92%!! I EVEN HELD THE PHONE OUT AND NOT IN A POCKET FOR 15MIN. PROBLEM SOLVED EVERYONE.

It's firmware or something that Apple can't just fix by software-update or something like that.

Nor do the iPhone 4, 5 and 7 seem to have this problem.

Take it back to Apple and demand a replacement battery.

Fingers crossed, but the newest software update (10.2.1) seems to have fixed my issues. I was up in the mountains all day yesterday without my phone switching itself off due to the cold.

It has been confirmed by Apple that the latest update solves the issue for most users:
