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

I went through a similar process without all the waiting, shows up for my appointment and in less than 10 minutes explained the problem and they ordered a battery. I was told the same thing that it would be at least 2 weeks but I happened to be there a week later and asked if they had a battery in and as luck would have it they did and in an hour and a half my battery was replaced and my phone works great. Best of all it lasts all day and doesn't die in the cold!

The recent news about the undocumented feature that Apple wrote into the OS explains a lot. We, a family of 4 all had our phones turn off a few weeks ago when trying to take photos outside. I mean it was light jacket weather!!!!!


I guess I never thought it could be on purpose in the OS??? Apple has lost much of my respect and trust!!!!

Hmmmmmm, I dunno maybe use higher quality batteries that don't suffer in the cold as much, like the ones used in the iphone 4 s for instance, I have an old 4S that is used for work it has far more charging cycles on it it is physically much older in years and doesnt go from 100% to flat in an hour outside in temps barely below zero like my iphone 6 does outside in the same pocket of my jacket. All these apple geeks who keep on saying it just works have there heads in the sand. There is a problem with these batteries, Apple are just too obsessed with making people buy the next generation item all the time they can't be arsed. Apple customer service amounts to just about sweet FA.

I've never heard any of my friends having this problem on any of the other Smartphones that are equipped with lithium ion as well. I own an iPhone 6s and had its battery replaced last year in the recall program. Since then I face exactly the same issue. Shutdown in 0 degrees C. Can't use it. I need to use my Xperia in winter times because of that. Ridiculous. No more Apple. I'm done.

I too have had this problem rendering my iPhone 6s unreliable as an emergency back up for 3-4 months of the year and useless as a camera in the snow. I know this isn’t consistent across all iPhone 6s ( comparing with friends in same conditions at the same time). I therefore to to the Aberdeen Apple story where I bought the phone. I was told categorically that there are ultra sophisticated sensors in the phone to shut down and prevent the circuitry damaging itself - the salesman went on to suggest it didn’t happen in later models and that I could cure the problem by buying a later model of i-phone. I considered the explanation to be techno-BS as it was not always unreliable in cold weather and as pointed out was not occurring with other 6s phones. The proposed solution to upgrade is outrageous for a phone that was less than 18 months old. Unless I get a proper response the next phone will not be an Apple.

I consider the battery has deteriorated and Apple are not responding here for fear of the cost of replacing faulty batteries.


Come on Apple either reply with official explanation or offer a fix.

The replacement system is the biggest joke ever. Apple loves to waste your time.

After speaking with someone from apple on the phone and determining my phone needed a new battery I got an appointment to have mine replaced at the "Genius" Bar. When I arrived I was told they would need to order me a battery and I would need to return in 2 weeks once it came in. So after wasting over an hour of my time on my first appointment I get to go there again in 2 weeks and spend another 2 hours.

Way to set expectations Apple!!
