iPhone 6 battery dies in cold weather

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 have posted graphs in earler posts that show this behavour in Colder weather.

Apple have huge problems with their batteries when they start to get a bit old (like 1 year).

When the battery is new, there is no problem at all to use it outside in 0 degrees C (32F).

If you do the same test 1 year later when the battery have a few 100 charge cycles, the result

will be that the battery goes from 100% to 0% in a few minutes.

And when you take it inside again and warm it up (without charging it) it will start up again and

have maybe 50-70% battery left.

A new battery will solve the problem, for a while...

Hi

Go to apps store download Battery life it will test your battery condition.

If your battery is 2 /3 years Old it will need replacing make an appointment at Apple store.

Or go to Support.apple.com for posting details use SIMCARD in other phone if you have one Mine took 4 days.

If you need the phone for emergencies, replace the battery, your life is worth a few bucks.

Batteries are replaceable, people do it all the time. That addresses the problem perfectly.

That lithium powered devices don't work at temperatures below freezing is not new, until battery chemistry comes up with another electrolyte it is unlikely to change. And it is not something the manufacturer of the device being powered that way can change. Unless of course they also make batteries in which case they can invest in research.

You are quite right, any lithium powered device is not to be trusted when operated beyond its acceptance range.

Fortunately the same problem requires the same remedy as it did the first time, when it runs out, replace it. That batteries do not last for ever is not a secret.

Here we go again.... Days after installing the new iOS to my iPhone 7, it started dying, without warning. It has happened twice when hiking in moderately cold weather, i.e. 37 degrees. I used to have this issue with older iPhones where when skiing with adequate power it would simply die, without warning until I plugged it into power, and then it would show 30%+ battery life.

This JUST started happening, coincidentally? I called Apple up and they told me "it is a known issue for phones to die in cold weather." I disputed whether 37 degrees is cold. It is clearly not. To be clear, the phone is in my pocket mostly during my morning hikes, but when I take it out briefly, it just dies, no warning whatsoever and now way to turn back on, even though I am certain there is power remaining.

I was told that I need to backup and uninstall everything and reinstall the OS, which takes HOURS, to narrow the issue down before they will investigate further or replace my phone with the Apple Care I have paid for.

I love/hate Apple!

I am also facing The same problem. My battery was 30% and I was taking pictures outside and just after one picture.. The phone died. I read somwhere that Lithium in battery performance degrades with cold temperature.Howeve, Apple should keep that in mind while selling phones in North America, where the mercury remains below zero degree Celsius almost 70-80% time during the Winter. That means we won't be able to use the phone outside. On top of that they are now saying to upgrade the OS to fix this, which is another BS as my wife did the same and her phone is freezing like anything.... These are just negative marketing strategy to force people to buy the newer version of iPhone..unacceptable.

So, erase and reinstall the software, make a backup before you do.

It is not a software problem.

Its hardware.

I have been investigating this problem ALOT for almost 2 years.

If you look at older posts that I have posted here you can see graphs

with test-results when I have tested the battery in a controlled Environment.

P.S., I was screwing around with my iPhone 5s afternoon it “died” at 92%, and found that attempting to power up shows the dead battery screen, and trying again immediately after that will actually boot the phone. As long as you do this after placing the phone in a warm environment for a few minutes, you shouldn’t need a charger.

my battery is 2 days old, just got it replaced on Monday with a new one. 87% charged, left it in the car at 29F and powered off, came back to my car 9 hours, turned it on and down to 10%. SO MUCH for meeting the storage specifications!

checked out "battery life" app and it says the battery wear is 15%!!!

turned on my car, jacked up the heat, stuck the phone to the vent. After warming back up, the battery remain near dead but the battery life app says the wear is 0% now.

let's just say don't depend on your iphone in cold emergencies. and let's stop ignoring that there's a real problem. Otherwise they WON"T do anything about it.

This has been going on since the iOS 10 update. I have tried everything and nothing works. It's a software issue and Apple just doesn't care because it affects older models like the 6. I am living with the problem till I get a X, but will take it out into the elements right away and see if the X is any better. If not I will have to change platforms because I am outside a lot.

Yes, batteries do lose performance, but this started to happen right after an early iOS 9 update, did not have the problem before. Also, my other devices that use Li batteries do not have the same issue, including my iPad. I am in Canada so am well aware of battery performance in the cold, and although I am not an electrical engineer, the symptoms scream software not hardware.
