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.

From chat. Here's hoping!


Alright, at this time, we’ve looked over some information. We see that your device is not eligible under our unexpected shut down program but we’re aware of this issue and currently investigating this issue with the device shutting down the way it is. I recommend that you look forward to an update at this time. There were no issues with the diagnostics at all.

I recommend that you look forward to software update via iPhone, but I can definitely get you over to our local Apple Store or Apple Service Provider to get the device examined, but definitely we’re still working on this issue with the devices shutting down the way it is.

It's all ********! Apple tells us that there is a small amount of phones exposed to whatever, but everywhere i ask, people all over the place are experiencing the same problem. It's too big for apple to admit.

You can try whatever you want, but i can assure you: it won't work! I've tried it all. It's an internal problem. I hope your battery will continue to stop at 30%, because mine is sometimes even quiting at 80%. And when you really need your phone the most, when your in the middle of nowhere, searching for an address, and really need to call home, that's the moment you will be the most disappointed about your old friend Apple!!!!!

This has nothing to do with cold weather... Apple has a problem, and they keep us in the dark. Battery stops at any given temperature, at any given day, with whatever is on the phone. When you empty your phone, reset it, do a repair mode, even do a apple chat and diagnostics, you will still have the same **** problem... You remember the problem with the Toyota Prius a couple of years ago? I'm afraid this is a similar big problem that can cost apple billions, if they admit it. So they just don't. They are big enough, so why should they? Even a little bit of support is too much to ask. When i ask them if they can contact me when the issue is resolved, they just say: No. You have to check the website for news. They don't contact you! It's too expensive. That's what has become of your old friend Apple on whom you relied on for so many years!!!

Shutdowns at 40 degrees F and 35% battery are no longer occurring now that my phone and battery have been replaced with a new version of the same model (6s+). I restored using a backup of the failing old phone with all the latest updates, so I don't see how it could have been software in that case. My failing old phone also showed nothing in the diagnostics according to Apple store person.

I live in Holland, a country where it's never cold. It doesn't matter what temperature it is... the phone is not working correct and apple can't seem to find the problem. If they have to recall al iphones, they can shut down, so they try to solve the problem by ignoring our questions, hoping to solve the problem in the mean time. Sadly.

Your old (expensive) friend apple, on which you could count on, has left you in the cold!

There isn't one but at least Apple does post the operating temperatures of their device which a lot of manufacturers do not do. I searched and found one article from back in the Galaxy S2 days where they tested various phones and found it worked best in cold weather. Whether or not that is true today I don't know as they still don't post operating specs.

What is strange here is that I brought my iPhone 6 when I went skiing in Sweden right after purchase. Worked perfectly. To be clear, Sweden is **** cold.


Yesterday, I went in my car with a fully charged iPhone. One picture and it died! It is about +2C here.


The phone is over 2 years old but I just don't know if this is software or hardware related as why would the battery only behave this way in the winther?

Maybe in African continent? Oh, wait... most people there can't afford one... let's talk about the price... i think you can at least expect some support. But no. Apple is so big, they don't care about support. It's all about money these days.

Temperature? ********. The problem is there. 35 degrees celcius, or -10 degrees celsius. Maybe more often at -10, but anyhow.

Batteries wear out, have you considered that yours may have?
