iOS 10.1 Battery drain

Hello genya,

Yes, it was batteries all along. New batteries resolved the issues. iOS 10 only hid it. Myself and a few other Apple customers worked hundreds of hours to bring this in the open with proof. You likely read some articles I contributed to. Key in this process was 'proof.' Some of us had no coding science but enough electrical knowledge and studies to identify the battery as the only possible culprit. Hopefully when you left the forum a year ago you went and changed the battery, not the phone. Some geniuses knew, some did not. Either case, in the end, Sr Apple management made the decision we wished for: full admission and a solution. My preferred solution is a new tech, solid state batteries, will see about that.

how awkward...

Yes, finally, after over a year we have closure:

But, it has left a bad taste in the mouth and a hole in many people's pockets who have upgraded at a substantial cost when there was no need to.

Honesty and clarity, thats all we want Apple, and in a shorter timescale please.

My iPhone 6s battery, which was one of the faulty batch and was replaced under warranty just over a year ago, is now showing as bad. A year for a premium phone battery is simply not long enough.

I will be changing the battery on it when, as announced, they reduce the cost of the battery replacement.

My 6s works perfectly well and does not need upgrading.

I noticed you have an iPhone 5 which is not on the list for the battery replacement program... You can probably just purchase an external battery case for your phone like I did for my iPhone 6. That seemed to speed it up.

I just don't understand it, but even my old external battery packs and battery case, despite being old and degraded, still have the ability to power my iPhones without causing unexpected shutdowns or slowdowns.

Next time people appear to know things better, odds is they are. Some of the article links you read on the subject, ref it being the battery, was very fortunate to have contributed to that. Took that long for everyone involved to breakthrough to the top Apple leadership, but we did. Was battery, liquid and chemicals all along.

Told you so that it was the battery.

I have also been keeping track of my wife's iPhone 6. She is not a heavy user, looks after it pretty well and uses an official Apple charger.

I checked her phone using CoconutBattery, screenshot below. I bought it for her on our Wedding Anniversary, September 2015.

22 years and still going strong.

This makes the phone about 16 months old, though it was manufactured in May, it was bought from the Apple reseller in Gibraltar BNIB September.

If it were a year or less, then the 79.4% capacity would be a fail and would be replaced by Apple as a failed battery.

So, I can conclude one or other of the below:

• Apple iPhone batteries are designed to last about 18 months
• iOS 10 has also got to her iPhone

Once the experiment on my 6s is complete, I will then know how long a new battery lasts before reaching the magic 80% replacement figure.

Adrian.

gentlemen, a reminder from Apple Support Communities Use Agreement. Note:

Submissions

Stay on topic. Apple Support Communities is here to help people use Apple products and technologies more effectively. Unless otherwise noted, do not add Submissions about non technical topics, including

1. Discussions of Apple policies or procedures or speculation on Apple decisions.

and

1. A submission created solely to advertise a book, service, software or some other item for sale.
2. Any reference, including a link, to a commercial item that is not directly related to a relevant technical support question or answer.

Your is a truly heartfelt testimony, not easy hearing it has given you so much troubleshooting issues. For your post I think some pointers may help.

1. If doing troubleshooting by phone, you can request an email copy of the incident number and description. It really helps long-term.
2. If you have Apple Care, Apple told me over the years that the coverage extends beyond it if the issue in question started while under warranty. And why that incident # email helps.
3. Measurement Apps do not work. i tried four for the argument's sake, they really do not work. Some even reported a completely wrong original battery capacity! Or a 10% health variance. Have yet to see any of them endorsed by Apple. It being in the Apple Store does not mean it has some Apple engineering stamp.
4. IPhone reset works pretty well. On average, up to 30 min full restore via Lightning. Stopped counting how many new or older iPhones I helped friends and family with just a Backup followed by a Reset. In addition, the Genius Bar has additional firmware reset options not available to us. I travel sometimes through unfriendly countries where they dump all sorts of bad code via SMS. I learned to trust the Reset as a really friendly tool when back in North America.
5. Battery University is the best, PhD grade, peer-to-peer reviewed start point on learning about Li Ion technology. They cover everything, with charts and pictures. Some bits will really surprise you. For example, no battery ever works between 100 and 80% as it does 30 to 0%. The electrons move differently when fewer Li ions in the liquid. And the module has to make sense of that at each level. And as the Li gel wears out, the numbers come out of sync. Beyond 600 cycles in 12-14 months, batteries are done. Cheap ones can fail in 2 months, below 100 cycles. They also tend to fail with similar symptoms: out of sync numbers, unexpected shutdowns, % jump when discharging. Rarely will they just overheat, swell and burst in with flames, as it happened to the 55incidents/17bn$ Samsung.
6. If you agree that some users resolved the issue by replacing the battery, and do what the dozen did successfully, up to you to reconcile that with your iOS statement. Someone here is even throwing 20 hrs a week Pokomon Go, and admits being unable to recreate the issues or kill his battery as he experienced prior to battery replacement.

The rest of your points are heartfelt, and Apple feedback http://www.apple.com/feedback/iphone.html is best for that. if whatever you read here helps you resolve the issue 100%, that is great and hopefully you return and report success.

My iPhone 4 with it's original (over seven year) battery works great... Fast as ever! Same with my even older original iPod touch. Unsupported now, so I can't upgrade it to the latest iOS with slowdown feature.

Now, my iPhone 6 on the other hand...

have not really seen here any apple apologists, but it is most unfortunate that your expectations do no match reality. Getting real is as smart a choice one can make, and achieving internal nirvana. Had a fantastic dinner yesterday with friends; also asked a 5S user for screen shots. 3 years old, 10.2, 94-99% battery health. Just works. All theirs worked.

it is unfortunate that, unlike various users whom posted here, you just do not understand that the life expectancy on daily used batteries can be as low as months to one year. Or 1 day in the desert. This is an industry wide reality, no matter the manufacturer. Some people have no flats ever. I only had one once, a 180mph blowout on a belgian track.

if you dislike tech reality (and Android issues will make you scream as much or more), perhaps avoiding mobile devices is the best way to avoid extreme displeasure.

Hello, me again, just hooked up my iPhone 6s with the battery replacement and checked coconut battery.

See screenshot, my battery was replaced by Apple on the 22nd December so I have been running it for about 17 days.

1632/1715 = 95% capacity, I will carry on doing these tests to see how this deteriorates with time on IOS 10.

Adrian.

Does not look good. Do you have a screen shot of the apple internal reporting, vs the app?Posted earlier a screen shot of a friend's iPhone 5S 10.2 with 500+ cycles at 99% health... My 6s with 10.2 hovers at 99-100%, 120 cycles...Also plsvn's comments that he was told of another hardware issue (besides the known battery recall issue), does raise some questions about what is it we are not being told...

My battery charge randomly falls from 30-40-50% to 3-1%, then it shuts down if I don't plug it quickly to a battery charger.

The affected device is an iPhone 6, 64 GB and the issue started with iOS 10.1.1, still here with 10.2.

Subsequently once the iPhone is plugged, the battery level jumps from 0-1% to 30-40-50%.

Today I have been able to get the screenshots of that recharging anomaly, see below.

NOTE: the iPhone is charged with genuine Apple battery chargers only.

Cheers.

Luigi

For the record 10.2 is no better. I'm losing 10% per hour on standby and this is a screen shot of mine that says Siri is taking battery down even though I've now turned Siri off!! This drain rate = 40 times the normal drain rate on standby. I usually go down 3% over 12 hours on standby. Iphone 6. iOS 10.2
