iPhone 6 battery dies in cold weather

I have the same problem. The last 1-2 weeks when I am running and listening to music with no problems. If I then want to go into my iPhone then it dies completely and can't be restarted. To day I was running with music and stopped to take a picture and it died. I tried to start it again but got the empty battery logo. When I came home and the iPhone still was very cold (running for almost 2 hours in -3C) I plugged it to the charger and it showed me the empty battery logo again. I starts with the apple loge and when it is ready it shows me that the battery is at 75%. I have experienced this a couple of times. Last winter I didn't have that problem so could it be a software error that is introduced in a software update during the summer?

Same problem here, but with an 18 month-old 6 Plus. The battery level shows anywhere from 30-60% then suddenly dies. When plugged back in to power, it jumps up to near previous level immediately.
It's worked fine all year, and now that the temps are dropping to around 10 degrees C (well within stated operating temps), the phone is suddenly shutting off every day.

Sorry I can't be of any help to you guys, but would very much like to hear an Apple comment on this one.

Frustrating that Apple won't acknowledge this problem and delete the post. My 6 is less that 12 months old and shuts down within minutes when temps are below ~40 degrees F. Really scary to not have a reliable phone at 55% charge (when my phone shut down tonight). Very very disappointing. Hopefully there is a fix...taking mine to Apple Store this weekend. Hope I don't get a forced "upgrade" to 7 w/out headphone jack

22 degrees F is about -5 degrees C.

I have been testing a bunch of iPhone 6 (both new and old) down to -12 degrees C (10 degrees F).

If there was a software restriction that shuts down the iPhone at 22 degrees F I would have noticed.

(im testing mobiles with IOS 10.x and I cant say if older IOS had this restriction)

Two days ago my iPhone 6s 128GB iOS 10.2 died suddenly without warning while on a walk with temperatures at 33F. Attempting to restart showed the red battery warning with 1% charge remaining. I plugged in a portable battery charger and the iPhone immediately rebooted and showed 70% battery. I seriously doubt that the battery charged the phone to 70% in the time required to reboot.

After a few minutes of continued walking at 32F, I unplugged the battery and the iPhone 6s continued to operate for about 5 minutes when it suddenly crashed again with about 75% battery showing before the crash.

I have been experiencing battery problems since the installation of iOS 10.1. I did not notice any problems with previous versions of iOS.

SAME ISSUE! Iphone 6s, phone in my coat pocket isn't enough to keep it from shutting off with over 50% battery left. I have to carry a work phone and my Samsung S7 is just fine, sitting right along side the iPhone.

I'm well aware that lithium ion batteries don't like the cold. But I also know that low quality cells behave much worse in the cold.

Same issue here.

iPhone 6s 64GB bought brand new from Apple store 6 months ago.

The phone would turn itself off in temperatures lower than 10 degrees Celsius even when the battery shows more than 70%. My wife has a 6s 32BG bought a few months earlier than mine but her phone works fine in cold temperatures. Bought a 5E for my daughter at the same time when my 6s was bought. Her phone works fine too in very cold weather. The 4s and 5s and the iPod also work fine in cold temperatures.

When I phone the downtown Vancouver store, the fellow answering the phone was extremely arrogant and nasty saying there's nothing wrong the phone. The problem was that I didn't treat the phone properly! That's it. I am not qualified to own an iPhone.

Having same problem out of the blue with my iPhone 6 plus. Out running in 30-40deg weather on 3 occasions, battery was in the 40-50% range and then after about 20 min. of running phone dies and says it must be charged. After returning home and phone presumably warmed up the phone turned back on (without being charged) and indicated the same battery percentage as when it did just before dying. Currently running iOS 10.2

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.

I think the totalky same. Mine (iPhone 5s) worked all years until the winter 2017 just properly with ios 7 and 8, and I had no experience with it dieing from cold weather. Now it dies with ios 9 at 5 •C or so.

Same issue has my family - e.g. an iPhone 6s plus is only 12 months old and now dies with ios 10 at 5 •C either. It was not the issue with ios 9, what is important to keep in mind.

With regard to my message just above I forgot to mention that I am using an iPhone 6s 64 GB.

You know that Apple does not read these posts. All you can and should do is contact Apple through the bug / support contact form. They will probably ignore that as well but worth a shot.
