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!

My iPhone 6 was 26 months old and starting to shut down if I took just 2-3 pictures outside. Even when not that cold at all. When I got the phone I went skiing without problems!


I was recommended on this post to replace the battery, so I got it replaced on friday and did use it outside for pictures etc. this weekend.


All good now! I will no longer follow this thread.


Replace battery = Resolved

The reply i got was: it's not Apple's policy to contact you in this matter, so you have to check the Apple website on a regular base, so you can see if the problem is solved.

I mean: what an attitude!!! Can you believe it? I have a problem that is caused by Apple, and when I ask if they can send me an email when there is a solution for the problem, they say that I have to do it!

Cheap solution, but I guess it will cost them a lot of dear friends...

I'm experiencing this as well, although I hadn't considered the impact of cold weather until today. I am using an iPhone 6 (not 6s, not plus) that I've had for about 18 months. My wife and daughter have the same exact phone, though, and are not experiencing this issue at all.


With my phone, I've noticed during colder (below 30 degrees F) weather that the reported charge on the phone will very quickly drop off from 100% to the 60% range then to the 30% range and then cut off altogether with little or no warning. Last night, in particular, I had the phone plugged in and charging on my night stand. Before I went to sleep, I checked it and saw that it had charged to 90%, so I went to sleep expecting to find it at 100% the following morning. I awoke at around 3am to go to the restroom and checked the phone on my way back to bed, just to see what time it was. Instead, I found the empty battery with a red line. I was not expecting to find this. Sometime later in the morning, the phone came on and played the "awakening" sound and illuminated the ceiling in my bedroom with bright white light. At that point, the battery was reported to be 36% charged. It has remained at 36% charged throughout the day, in spite of nearly constant usage on my part.


There appears to be a recall on batteries for the iPhone 6s, but not the iPhone 6. I checked my phone's serial number and it is not covered by this recall. I feel that it should be. This is not proper behavior for a lithium ion battery in any weather.


For now, I've made an appointment to go to the Apple Store tomorrow and have them look at it. I suspect it'll need to be replaced, so I'll be out $79 + tax for that.

I have had the same issue and honestly, I got so mad this weekend that I am looking into dropping Apple all together and I have been with them since their first iPhone. It was about 25 degree f outside and I wanted to take pictures. Every time the camera is selected, you have a matter of seconds to take a photo before the phone turns off. Give it 1 min and it will turn back on and show its actual battery percentage (85%). Try to do it before that min is up, it will give you the dead battery sign and not turn on. Everyone out with us who had an iPhone had the issue. Everyone you had a Samsung or HTC had no issue. Also, my old 5s never had issues - even is much colder weather. So, the articles about it being a lithium ion issue is false as no other phone, all of which have a lithium ion battery, had issues. I was so upset as I have missed out on pictures of my daughter playing on the snow etc and now I missed a huge fishing tournament. At this point, Apple products need to step up their game or they will lose many apple customer such as myself. I am at the point of selling my iwatch to get a Samsung phone and Samsung watch. A phone is no longer just a phone anymore and it needs to hold up to better standards.

It was about 25. But either way, why would only starting the camera cause the issue? When not being touched it's fine. Also, lithium ion batteries can output down to -2 F so why are apples operating temps so high? Charging temps make sense at 23 but operating does not. Also, why was there no issue with the previous versions? Doesn't seem there is an issue with the 7 either (totally guessing as I cannot find a complaint anywhere for the 7).

Same issue here. iPhone 6s, 1 year old and 10 days out of warranty when i first took it in, shuts off in temperatures below 45 degrees F. When plugged in for charging battery shows 30%. Up to date iOS, 10.2.1 but happened with previous iOS, and all battery saving features in use. I'm told I must pay to have the battery replaced and 'Perhaps' if it does not fix the issue I would be refunded the battery and installation fees. Frustrating to find other users with similar problems and no resolution from Apple.

I have this issue as well with my 6S--not as noticeable as we live in Texas, though. The first time it happened, we had "cold spell" and it shut off at 28 degrees while I was on a run. It's always had poor battery life compared to my husband's iPhone 6, but this was the first time it completely shut down.


Last week we went to Colorado to ski...it was cold 3-15 degrees the whole time we were there. My phone would consistently shut off after a few minutes outside. I put it under two layers of clothing next to my body and that wasn't enough--I had to go into a building and warm up for 15 minutes before it would turn on. Interestingly, tons of other people had no issues using their phones in the same conditions--including my husband and his iPhone 6.


I went to the Apple Store today and was told to restore the phone. It was clearly having software issues on the diagnostics, but they insisted the battery was fine and it had to be the software. I'm restoring it now and we will see if that helps, but I kind of doubt it. Going to be hard to test now too!


I'm peeved--the Genius bar rep insisted that these batteries are not reliable in temps below 40 and it must have been my "high usage." Am I really supposed to believe that half the country shouldn't be able to rely on their phones for half the year?

I live in Toronto and have an iphone 6s 128GB that I've have for about a year and a half. My iphone constantly shuts down if I am outside in temps below 10 degrees celsius. It will go from 100% battery to dead in less than an hour in my pocket. I fish alot and this is very problematic since i'm frequently outdoors in these temperatures and if i need my cell phone it will be in emergency situations since I'm off the beaten path!

Iphone 6S 128G user here. My phone is not among those affected by the recall/replacement issue.


My phone is about 18 months old now. I used it skiing last February with my drone (Hexo+ drone is controlled by the iPhone via bluetooth, using the phone's GPS so not exactly battery-friendly usage). I got around half an hour of flight time from the drone before it's batteries (the drone's) were depleted during which time the phone was in the top pocket of my rucksack, so not protected from the cold in any way. The phone remained in the chest pocket of my mid-layer the rest of the time and retained sufficient charge to last all day, without having to turn off 3G/Wifi/Bluetooth or resort to low-power mode.


This year, my phone is going from a full charge to dead within 3 hours, while in an inside pocket, with airplane mode and low-power mode enabled.


When I plug in my charger at lunchtime, and the phone warms up, it will wake up with between 60% and 80% charge.


I can see it go from 30% to dead in my hand in the time it takes me to try and make a call or check the weather forecast while outside.


There's definitely an issue here.

I forgot my Iphone 6 on Monday in the car. On Monday night we were hit by the blizzard so I couldn't get back to my iphone until Thursday. I have been trying to charge it for 2 days in a row it is completely unresponsive. Contacted apple and they say the iphone doesn't tolerate cold temperatures because of the chemicals in the battery. At this point I was told to leave the iphone in a warm place for at least 48 hours to see if it charges, if not i have to go through repairs.

I had the same issue with my iPhone 6+ for a long time but finally solved it.


This is what I did:

Make sure you have a backup, either on iCloud or your computer

Plug your phone into your computer and via itunes restore your phone to factory settings. Important that you do this from iTunes and not just on the phone as that will not reinstall the firmware.

Set up your phone as a new phone and re-download your apps again, they will be found in AppStore under purchased.

Photos will download automatically as well as your contacts if they are in the cloud, but you will have to set up your email accounts again.


Not only did this solve the battery issue, the phone is now faster and more responsive again.


If anything goes wrong you can always start over with a new reset and install your old backup, mind the risk that you might download the original problem again.

My phone has a battery that dies as soon as it is any way cold . Phone shuts off and I need to plug it in . Once plugged in it is back to around 50 percent . I took it to apple and they said the battery is running at 95 percent . I am a business owner and feel cheated by apple once again , they have no reason for me at all why my phone is doing what it is , but yet you log in here and it's happened to millions of people . Am I stuck dropping another 1000 dollars on a phone so I can do business outside without my phone dying ???? Someone help because this is rediculous . Thanks
