iPhone 6 battery dies in cold weather

i have 190 cycles in moderate temperatures. I am/was an Apple fan, so i treated my phone like i treat my wife; with respect. But i can assure you; the last couple of weeks i have recharged my phone (6s by the way) a whole lot more and so 300 cycles are nearby... apple wins, again.

If having a phone at sub zero temp is so critical, that you shouldn't have it if you live in such a place, then selling iPhones in North America and Europe is a selling devices which are expected to fail due to the temperatures whic occur there every year for a period of weeks/months.

What part of this is not clear to you?

1) None at all. Just think it's getting out of control - people are not actually talking about their business running skills. ***?? Because of these posts - other really meaningful posts get lost.

2) true that - they are linked to the battery. so I can be wrong.

3) I wouldn't count on Apple - Press Yes, but not Apple. If you want to get Apple's attention there is a bug report page.

4) Believe me, I'm really disapointed with how the phone works and how Apple is (not) handling this, but I still like their products, and that's why it hurts so much ;-)

Thank you for posting that link! I just checked and I'm in the "battery replacement program." It does seem that the problem is more widespread than Apple has acknowledged. To all other users posting about operating ranges - shouldn't we be able to expose a phone for two minutes to 40 degree F temps while still holding it in our warm hands and expect the battery to keep operating? Mine did for the winter of 2015-2016, but now it goes from 60%- dead in a nanosecond.

That may be true, but the low temperature testing in Finland doesn't support it, all the phones they tested had great difficulty staying alive at sub zero temperatures, this included Nokia, Samsung, HTC etc, the iPhone (a6 and a 6S) were average.

They all died around -4 regardless of who made them.

"Simply the lithium battery does not perform in cold weather. Nothing you can do about it"

Its true that litium batteries perform bad in Cold weather, but the discussion is more about if the iPhone 6 (6S) batteries perform worse than they normally should.

And they are.

However, the in this case, we're dealing with quite a few iPhone batteries that die at lower temperatures that are well within Apple's stated operating range, and they've at least partially admitted to a problem without, so it seems, officially recognizing the scope of the problem. Batteries are considered to be defective once they fall below 80% of their original capacity. iPhone batteries are said to be reduced to 80% capacity after only 400 full charge cycles (average two years), which is already substandard, as other smartphone batteries tend to last 750 charge cycles before depleting to 80%. And we are hearing complaints here (including mine) about iPhone batteries that die at 5-10°C after only 13-15 months of use.

"All manufacturers suffer from the chemistry of batteries, and they all now use the same chemistry for their batteries."

There are acually 6 different "setups" of LI-Ion batteries.

Which one is used in all mobile phones?

I just got a 7 and it works perfectly outside. I have no clue what was wrong with the 6s if its battery was just cheap or something, but the 7 does not have the same problem. Dont think its software related based on this.

No, it is age related, your 6 became older than your new 7, so the 6 has an older battery in it, battery power reserves decay over time which makes them far more sensitive to temperature vs power issues.

This public forum is de facto serving to document the issue of iPhone batteries dying at temperatures within Apple's stated operating range. Apple has partially admitted to a problem by replacing batteries that are just over a year old, that should not be failing -- albeit while refusing to acknowledge the scope of the problem. An iPhone that is more than a year old usually has an expired warranty, so the fact that Apple is replacing some batteries means they are aware they have sold substandard batteries. Apple can quantify what that "quite a few" number is exactly, but they won't. Yet, it's significant enough that they took notice. You can keep issuing suggestions and imperatives to take them back etc, but as we are seeing, some people are falling outside of Apple's battery replacement program due to expired warranties or not having the right model or serial number.

"I have no idea, ask Apple it is their product after all."

Well, since you wrote that they all used the same chemical setup I thought that you knew.

I suppose that this means that you are not sure.

Anyway, It would be really intresting to know it they did some Changes (chemical) since the iPhone5S battery.

Unlike you I don't tell people what Apple think or how they reach their decisions, because as one who does not work for Apple I do not speak for them.

So I assumed your apparent knowledge stemmed from working for Apple, but I see now that you don't and are just guessing.

They all use Li-on batteries, the exact make up of the chemistry they use is not available, I prefer not to guess no matter how common it is in this thread.

Why don't you ask Apple to give you the formulation that they use.

I currently own an iPhone 4, 4s, 6, 6s, 7, 7+ and an iPad mini (yeah I know I have a lot of them 😝 )
Apart from the 7 and 7+, they are all between 15 months and several years old. None of the batteries (all originals) are having trouble in cold weather (I've been out in -15°C temperatures for hours), except for the 6s -- not even the 4s, which is infamous as a power-hungry model, and which I use as an extra phone to make calls or take pictures in subzero temperatures.
