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.

I think the totalky same. Mine (iPhone 5s) worked all years until the winter 2017 just properly with ios 7 and 8, and I had no experience with it dieing from cold weather. Now it dies with ios 9 at 5 •C or so.

Same issue has my family - e.g. an iPhone 6s plus is only 12 months old and now dies with ios 10 at 5 •C either. It was not the issue with ios 9, what is important to keep in mind.

Was on vacation, getting ready to take photos of a beautiful sunrise and my phone battery plummets ffrom ~80% to dead!! It was only in the 50sF so not even that cold. For the amount of money we py for these phones the reliability is an ultimate fail. My husband had a Samsung and a Huawei with him and they both worked!!! Been an iPhone supporter for quite sometime but I'm hopping off of this bandwagon. And this battery drainage with every upgrade is a joke

Yes, i have had the same problem since an early iOS9 update. Apple just won't even admit there is a problem! Also, which each iOS update my phone develops a new problem and slows down. I have a iPhone X on order and if there are any problems with it now OR IN THE FUTURE, it will be my last Apple device. For a top shelf company to treat loyal customers like this is outrageous. You can't get mad at the store or support staff, they are just doing their job, but I sure make my view known when I talk to them about the issue. 😟
