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!

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 their 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.


Does this?

Apple geek alert. Tell me something I don't know I am fully aware of the type of battery. Please tell me why an iphone6 uses more power with everything shut down in my pocket then an iphone 4 in my pocket with everything shut down. Both phones are doing nothing both phones are in my pocket one phone goes from 100% to nothing. The iphone 6. One phone is still at 98%, the iphone 4s. Both phones are doing nothing, everything is shut down. Your argument doesn't stand up and Apple do not admit a problem. The iphone 4s does not have a battery problem the iphone 6 does, get you head out the sand, why defend something that is obviously not fit for purpose. I will leave you to tell apple. I have better things to do than waste oxygen on more Apple geeks. It just works Hahahahaha! In fact dont bother telling me anything I'm not interested.

Alex my previous phone worked well in cold weather then all of a sudden when it was cold it would lose power fast , my new one was working perfect in the cold , never had and issue in the minus 20 temps but since last update appears that I no longer can take my phone out even when -5

Yet people I know with same phone that do not do the updates it works well in cold , very interesting in my opinion

Yes, I do this daily 🙂

I work with mobile phones and I do measurements before and after battery replacement.

Here is an iPhone6 that I replaced the battery on yesterday:

Graph 1 show the behavour BEFORE battery replacement.

Graph 2 show the behavour AFTER battery replacement.

(since the battery died during test 1 the graph looks a bit strange, and its in swedish but I think it will be no problem to understand anyway. Number of charge cycle counts: 179)
