iPhone 6 battery dies in cold weather

I think it's excellent that Apple publishes the operating temperature. This says that if I put my phone in the refrigerator for a while (above freezing, temperature controlled, easily measured), it has to continue to work. I will do this as soon as I can. Might be interesting if we got a larger sample size to do the same.

Putting it in such a wet environment is also not good for it.

I have done 20 tests so far this way and all of them points the same direction.

Older iPhone6 batteries lose almost all capacity when reaching 0 degrees C.

New iPhone 6 batteries still have around 80% capacity reaching 0 degrees C.

But as you say, it would be cool if more ppl test this and share their results.

I have checked the post you are reffering to. It's very helpfull, thanks. My conclusion is that my next phone will not be from Apple since it seems the problem is hardwired into the device and it requires either a costly repair (and giving away the phone with lots of personal info for the time) or throwing away otherwise a perfectly fine device and buying a new one (@cca 900 EUR) - and that doesn't sound very smart to me.

First of all this discussion is about iphone 6.

So all of you writting about replacement program for the 6s - please stop. Go and create another discussion about the 6s battery.

Second of all, from what iphone 6 users are writting it is clear that a 1 year old iphone 6 is pretty much useless in cold weather (for me the phone dies even at 10 C with 50% battery). It becomes a useless piece of metal.

We need to draw our conclusions from this:

- Apple will most likely not recognise this an issue on their side. They're saying we don't care about your 1 year old iphione 6 - go buy a new iphone 7.

If you want a phone you can rely on:

- you can replace the battery - where I live (Poland) this is about 24% of the price of a new iphone 6s, so I don't know if its worth.

- you can swith to another brand like Samsung or Sony as their phones don't appear have this sort of problems.

It's not easy. I love apple, my iphone, new mac pro, old mac air. But I guess this is not the same company anymore. Now you pay fot the design; not the functionality.

PS I can't wait for iphone 8 (or 7s whaterer they call it) 😁

This is also a hard question to reply since "old" is relative when it comes to iPhone 6 batteries.

I have tried to define "old" only comparing number och charge cycles.

The problem is that you have to take other things into consideration as well, like high temperature.

This is why Apple do not have any "Maximum charge cycles" recommendation for iPhone 6.

All mobile phone users have their own way to use them.

Some ppl put them in the sun in the middle of the summer and the temperature gets extremely high

which is bad for the battery health.

But if we put all the other parameters away and only focus on Charge Cycle Counts I would say

(from my experience) that an iPhone 6 battery is old when charge cycle count reach around 300.

And 300 charge cycles is very easy to reach within a year.

In my opinion it sould be ALOT higher than that.

Only if you think that not selling in 2 of the worlds largest markets is good for businesses. I don't, and Apple don't.

My statement was entirely accurate.

So tell me which markets you would sell in, and how that would assist your business (I assume that an expert like you actually has one)

1. What authority do you have to decide who can and cannot contribute to that discussion?

2. The problem between 6 and 6a are obviously linked as problems reported are similar

3. The more we are reporting such problems the more attention we will get not only from Apple but also from the press

4. Apple has done very little until now and this is a huge disappointment for many of us who have paid a lot for a malfunctioning phone

My point exactly, but you are obviously so "capable of running a business" that you don't understand that selling devices which are designed to fail in two strongest markets in the world is not a proof of being "capable of running a business".

Besides making people angry in the two most important markets (which is not very smart, right?), you can have legal problems. And that also doesn't sound brilliant.

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?
