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.

Regarding your response to FreyaSun, it may be a language thing.

  • "it seems" = it appears to be, but I may be wrong
  • "everyone I know [...] if their phone is in the second winter" = all the people I personally know, who've had the same phone concerned for two winters. In other words, this is limited to people in the person's immediate circle who have an iPhone 6 for about 14 months or so.
  • there is a difference between:
    - everyone I know is ...
    - it seems everyone I know is ...
    - it seems everyone I know is ... if .... [such and such condition is true]...
    - everyone in the world is absolutely (which seems to be what you're reading, but not what FreyaSun said)
  • there is also a difference between
    - "everyone I know is not ..." = nobody I know is ...
    - "not everyone I know ..." = not everyone, but some people I know ... (and since you "know of" people here in this community, I believe this is what you mean to say)
  • when FreyaSun says "everyone I know is ... if ...." it does not necessarily overlap (and probably doesn't) into your circle and imply that the people you know in your corner of the world must be experiencing the same things.

Hope that helps, because the problem with the iPhone battery is real and we are here to support each other -- not disregard other people's personal experiences.

Since you do not indicate the temperature, just "any way cold", here are the environmental specifications for the phone.


Environmental Requirements

  • Operating ambient temperature: 32° to 95° F (0° to 35° C)
  • Nonoperating temperature: ‑4° to 113° F (‑20° to 45° C)
  • Relative humidity: 5% to 95% noncondensing
  • Operating altitude: tested up to 10,000 feet (3000 m)
