It sucks because we went in sept to have them look at my wife's phone (it shuts down randomly at 20-40%). It was about 2-3 days before the warranty was about to run out and the Apple guy said her phone was "fine". Now we have to book another appointment and get it fixed finally. But it's a hassle and it sucks we have to go twice and they made us feel like we were making it up the first time. "oh you have Facebook AND spotify on your phone, that's why the battery drains so fast".

I have been less than impressed with Apple support regarding this issue. There has definitely been a "you're using it wrong" tone with any interaction I have had with their support team - be it online or in-store. And that is a very different experience than what I have had with Apple support in the past. Typically, I've always felt my issues were heard, believed and walked away feeling satisfied with whatever action was taken, or not. Have always felt issues were fairly managed. But this, and some recent, smaller, issues, have felt more in the "you're doing it wrong" camp. I had one person, in-store, recently tell me the solution to my alleged poor battery performance was that I should restore to factory settings every couple of months. And then slowly rebuild the device to include apps I like: noting performance at each step along the way. And if performance seemed to take a hit with any particular app, then don't install said app.
1) Ha.
2) Seriously?
3) Is that really Apple's expectation of their user base? Is their expectation that my mom spend countless hours restoring, reinstalling apps and noting battery performance of her phone? Seemed a very Microsoft approach - where there are several if/then recommended "solutions" that actually yield no improvement.
4) Again, ha.

FWIW. I restored to factory several times, not adding any 3rd party apps - just stock iOS apps, and saw the exact same "dead at 30%" performance on my 6 as when I had it configured with the apps and setting I except to be able to enjoy. Another person in-store, looked at my battery usage. He saw that I had 14 minutes screen time with some game (I can't recall which game at the moment, as games just aren't something I regularly do with my device) and said (with a somewhat smug tone) "Yep... There's your problem." When I asked him if me using an app on my phone was actually the problem, he said "well, it could be that the app is eating more battery than expected." OK. For a moment, let's accept that as "the problem." Is that really my problem or more indicative of a problem with device, the OS, the app approval process or something else?

Anyway, as I have mentioned in other posts... I ended up "qualifying" (a battery that is below 80% life cycle) for the ability to give Apple another $80 to replace my battery. While annoying, that solution has allowed me to use my device as expected and should hopefully get me to the next gen device. Is it late summer 2017 yet?
 
What does this have to do with the CEO? Do you expect it is humanly possible for him to babysit every single thing? This was a manufacturing error — likely a third-party manufacturer that failed to follow proper procedures.

Its called quality control - which Apple, as a mega billion dollar company - should be a master at.

Well, called Apple, they are going to send a replacement, so I can send my faulty one back. Not a perfect product, but perfect service does help a lot.
Have had some shutdowns, but they are a short interruption and thought: oh well, perhaps a software glitch.
 
Great, my iPhone 6S isn't eligible, but regularly shutdowns with 30% battery left :mad:
I'd take it to an Apple Store. I'll wager they'd make it right, even out of warranty. I had an awesome experience like this before. Apple CS isn't award winning for nothing. You might even get satisfaction if you plead your case to a phone rep, although you'd certainly have to get past the first tier.
 

Hmm... I had this issue. I brought in my iPhone actually a day before they announce it and called them about it, they told me it was know. The phone is fixed now but I during the diagnostics it was found my phones battery was still at normal capacity. It still qualified though for the fix. I think and still think there is more to the error than simple loss of capacity. I think the error might be in the battery control unit. So the battery does not know how much power is left, and shuts down. But I am probably wrong and maybe it is just this simple of an error.​
 
Mine shutdown when left overnight at the bedside circ 14 to 18 degrees c. Phone was replaced - all good now.
Glad to hear it, mine is on the list for battery swap so might make an effort to get it done and see what happens, can't hurt anyway!
 
Clearly, Apple knows this is not just a defect limited to the 6s (its not like there has been major battery manufacturing changes between 6, 6s and 7 devices).
If there have been no major battery manufacturing changes in the last three years, does this mean that all batteries in all devices using similar kind of batteries from all manufacturers are affected? And does this mean all devices from all manufacturers going forward are also being affected unless battery manufacturing undergoes real changes?

It is more likely than not that the same iPhone model is being shipped with batteries made by different battery manufacturers. It is also more likely than not that iPhone 7 batteries have more in common with Samsung Galaxy 8 batteries than with iPhone 6 batteries.

My guess is Apple is not really looking to announce some major battery recall program, spanning 3 generations of devices, with all the "uh oh" battery buzz in the industry at the moment. Nah.
Almost everything fails at some point. And there will always be units that fail earlier and those that fail later. If one in a million of a given component fails after one or two years, that is bad luck for the user but otherwise expected and unavoidable behaviour (you might call it unavoidable manufacturing variation though more often than not it might rather be an unfortunate usage stress profile). If that rate rises to one in one hundred thousand, this would probably still be called expected behaviour, just a slightly less good product. Only if the rate rises to one in ten thousand, might you call it at an unacceptable failure rate and compensate your customers.

There are probably industry standards to define a bad batch, but in the end where exactly you draw the boundary is arbitrary. And when it comes to performance degradations, you will draw the boundary more loosely than when it comes to safety issues.

And there's also basic reality in play as well:
make a zillion phones and a small number will likely have some sort of defect. without testing every single phone that comes off the line, there is no 100% effective quality control.
 
It seems like this particular issue was tied to a particular manufacturing misstep that was there for only a batch of 6s iPhones. There could certainly be something else around causing some similar symptoms and so forth, but that would be separate from this.

Which I would definitely be more inclined to accept if other users outside of a relatively small batch of IMEIs weren't also experiencing the exact same issue. Thus, the problem must reside within some other commonality between 6, 6 plus, 6s and 6s plus users than what they are currently claiming. Right?

This is what causes analysts to be wary of Apple. These issues it keeps getting and flatly denies exist, threats of civil actions later and all of a sudden theirs a repair programme for said denied issue... and an admittance it is Apples fault after all!
 
My iPhone SE sometimes shuts down with 20% battery left, when it is around 5°C and windy. As Apple specifies the usage temperature of the iPhone with 0°C to 35°C, I don't think this is "extremely cold"

Always thought that maximum operating temp was a bit funny. Many parts of the world regularly exceed that in Summer. It's not unheard of to hit 43-44 C in Australian cities, even 45 on rare occasions and parts of the Middle East or Africa are worse.

I've actually never had a problem though. I've only experienced a temperature shutdown a couple of times since the iPhone 3G after leaving it directly exposure to the sun for too long. Keeping it in a pocket helps to moderate extremes of heat or cold.

I hope the 7 batteries aren't affected but I'm not holding my breath.
 
Battery replacements are relative easy. If your interested look at a teardown of the device. Adhesive is the only bummer, but after you have done a couple it is no problem.
You might damage the old battery while getting it off the adhesive but as long as you don't damage it enough to make it explode, this is not really an issue, you are not going to re-use the battery anyway.

Or there could be some other things that can be causing similar symptoms, and they could even differ among those devices too. Some might have component or manufacturing inconsistencies too, others could be more related to already having many charge cycles or to usage patterns of perhaps the battery being depleted too often or used in hotter or colder than typical environments often, etc. Basically there can be other causes that might be similar to this one or might be different, and there could be multiple different ones as well. Hard to say one way or another really aside that for the moment this particular manufacturing one seems to apply to the particular batches that are associated with it.

You nailed it. Even if a game, or Facebook or Spotify, or whatever is draining the battery far faster than it should, why isn't Apple catching this in their App Review process? The other thing I always hear is "Turn off Background App Refresh." Huh? This is an even worse proposition. I'm supposed to limit the capabilities of my phone, capabilities that Apple itself has added? Why doesn't the phone "just work" with the software that Apple itself writes?

FWIW I have re-installed 10.1.1 on my iPhone 6 - thru iTunes - and it seems to a little more stable right now. A little birdie told me that a 10.x.x OTA update may be to blame. I didn't think iTunes would reinstall the same version of iOS (as I was already at 10.1.1, the latest), but lo and behold it did. The battery definitely does not seem very efficient any more...it's draining pretty quickly in Facebook right now as it sits on my desk. But it hasn't simply shut off at 60% or 80% or whatever.

My battery life has been pretty damn good for the year or so I've owned mine. That said, I bought the 128 because I didn't want to buy a new phone for 3+ years, so I'm taking the new battery at 4:15 today.
 
We knew most iPhones don't like being exposed to water. Who knew it doesn't like air either :p Use your iPhone only in space :D

Totally agree on the larger "everything fails" reality. I mean, my 6 device is a solid 2 years old now. And has seen steady, dependable daily use all up until the past few months. And I know battery life cycles are limited and there and endless sea of potential parameters than can effect battery performance/longevity. All understood and completely accepted.

Where I struggle, is with their claim that it only effects a specific batch of 6s devices when other devices are experiencing the exact same issue. That's all.

Again, I was able to purchase a new battery and my 6 is back to functioning as expected. I share my experience here so that other non 6s users experiencing the same issue as the 6s, can take some comfort knowing they're not alone. With the ultimate goal of helping the community be as informed as possible. I share my experiences with Apple Support with the ultimate goal of helping make the overall Apple experience as "magical" as possible for all users. Power to the people.
 
Had a similar issue with a MacBook Pro, which shut down at around 30-32% battery charge. Ended up replacing the battery.
