iOS 10.1 Battery drain

Hello.


Updated my iPhone 5 to iOS10.1 and have been having battery problems.


1 - It jumps from 30% charge to 1% in a few seconds then shuts down.


Now here is the stranger part.


As soon as it reboots after connecting to a charger it show 30% charge. When I unplug it right away it still shows 30% and runs like nothing happened for a good few hours.


So it goes from zero charge to 30% in the time it takes to reboot? Strange.


2 - Shutting the phone down at night with a good 80% charge, it won't reboot in the morning due to no battery charge. I plug it in and its back to 30% in a few seconds.



Thanks for any suggestion in advance.

iPhone 5, iOS 10.1

I have almost verified that whatever the root cause of this, sudden temperature and/or humidity, make it worse.


I had charged the phone up to 100% and when I was out on a very cold day, I saw the remaining percentage go down to 4% in a matter of an hour.


I then verified that it stuck there for another hour and then went off.


Next day, this temperature difference didnt' happen and the device remained in a relatively short temperature range and worked flawlessly.

My daughters 5 had the issue and I used a factory install to fix it.

I posted a series of Progress Updates. #7 about what I did. Page 81 of 84 so far.

I had the phone up and working well for about a week. Update #8 everything was still working fine. Page 82 of 84


Then last night, I hosed everything by re-installing from a backup. I had noted in a previous post that installing a backup instead of a clean install seemed to not work.


So a phone that has been working fine for a week now & holding charge for longer that 30 hours.... is back to the battery indicator ticking down in chunks and the phone spontaneously shutting itself off at less than 5 minutes.


I guess I need to go back and re-do a Recovery Mode Factory Restore and then not try to put any backup on it again.


I think I got ahead of myself with overconfidence and the wee hours of the morning.

Better don't feed the troll! (~Belisarius~)


No idea what his motives are to flood this thread with his Apple-friendly gibberish.

There clearly is an issue that he refrains to see.


In our company 81 out of 100 iPhones (6, 6Plus, 6s & 6s Plus) are affected by this issue (as is my private 6S Plus).

Ignorance is when someone does not understand technology, critical thinking, scientific methods of analysis, and proceeds with wild anecdotal speculation. It is not Apple friendly, it is merely critical thinking. It being confused with Apple friendliness testifies as to the limitations of your premises. If a single student in a critical thinking or analytical technique class (taught in any govt agency, corporations, think tanks etc) came up with jibrish competing hypotheses and ignored evidence to the contrary (i.e. hundreds of millions working iPhones), umm, we fail him?


Good for you doing a thorough company wide investigation and determined that 81% of your iPhones are affected.


Iphones 6 and 6S have a similar battery cell. What will Your Wisdom do or say should Apple issue a recall, replace your 81 batteries and they then work? Come back here and apologize for poor critical thinking?


if they are fixable, what then? Blame iOS? Nope, you will go hide in real life.


Why did Samsung issue a recall? because the Android OS caused 55 to catch fire? LMAO I will use these example as textbook argumentative fails in all areas of critical logic.

Jan 2, 2017 7:31 AM in response to alexanderfromnicosia

Alex, what are you doing with cold temperature, it is known that cold stops Li Ion reactions inside the cell. In Canada anything below 10F (and we go easily to -30F) we must keep them near our chests. no matter the brand.


it is also terrible to the long term health of your battery. A single cell freeze could kill it... Why the Russian roulette?

Jan 2, 2017 7:39 AM in response to Mjolcresure

It is highly illogical to state that IOS 10 had nothing to do with these battery failures. I don't understand why (~Belisarius~) is constantly stating that these failures are something that was expected from regular battery usage.

Of-course millions of iphone users are perfectly fine with the update, but that isn't reason to believe that EVERYONE is fine. Its impossible that thousands of unlucky owners (including ones on this fourm) reached the tipping point of their lithium ion batteries at the exact same time. Lets not forget this affects iphones 6/plus AND the S series (unsure about iphone 5), phones manufactured and sold with a year gap between them- thus having huge variance in the remaining battery life, and yet both generations of iphones are affected during the same period. Adding to this chain of supposed 'coincidences' is the release of IOS10 which was clearly the point when people's Iphones started experiencing battery problems.

Your input on this is appreciated ~Belisarius~ but it seems to be incredibly subjective and ignores the plethora of points raised by the affected users. Most of the users here are loyal apple customers and really don't even blame Apple for this, we just want them to resolve it.

Restoring the device or recharging the battery from 0% (and other advices suggested here) don't work for most users. Replacing the battery/ device isn't an option for others because we've expired the warranty/ apple care date and aren't ready to simply pay for a new battery because of the possibility of a fix coming with the next IOS update. If this fix isn't possible through an update, then an official acknowledgement from Apple would be appreciated.

Thanks. i'm on phone to apple currently. they say only a 6S problem is know. is this rubbish?


AppleYoda, according to tech references, Apple identified a battery defect in specific batch numbers. No idea if they have a common manufacturer, how many millions etc. So they are replacing those as defective. Each phone Ser number is matched to a battery batch. Symptoms are similar to the current iOS 10 drain forum, including SSEs. The issues may have started once the that batch of 6S approached 300 or so hundred cycles.


Whether or not this will be extended to other batteries, and iPhones 6 that is another topic and within Apples Operations division. Also, if the issue is identified retroactively, or if it already has, but covers, say, 200 million iPhone 6, the numbers then rise to billions of $ warranty cost. I think you understand what this means.


Even within a specific Ser/Batch, not all defective batteries just defect. But they are likely to.

"but it seems to be incredibly subjective and ignores the plethora of points raised by the affected users."

Quite the contrary Manzar, anyone speculating or blaming is incredibly subjective. there is nothing subjective about:


1- Reseting phone (after calling apple support)

2- Replacing battery (apple care or buy)

3- Replacing phone (Apple Care, Apple Swap or outright new trade in buy)


It is as objective. Does not care about causality, and the point is users needing their phones have the choice to A waste time trying to mutually self soothe in iOS 10 bashing, or B- try the steps above in 24 hrs.


When my iPhone 5 battery died during the iOS7 install, after 3 hours troubleshooting I cut it off, when and got a new battery, issue resolved. Clear, logical, methodical. Did not contribute more to the "iOS 7 Battery drain" forum other than to say battery swap fixed it.

Jan 2, 2017 7:48 AM in response to losdelrock

The good thing is what will be will be. If the OS is causing some issue it will be fixed


In my circle of relatives and friends during the holidays more people had an issue than have not since the upgrade.


For some it is a reduction in functionality, but a noticeable drop by 1/2-2/3rd of what they normally had for daily usage.

I thought one of them had said they upgraded a couple of their 6S batteries under the lemon Lottery but they still were having problems, but I am not entirely certain so this is just an anecdote.


Belisarius hypothesis is that the underlying problem is a battery issue which was unmasked by the update due to some sort of stress.

For everyone noticing it, the iOS update is what changed everything for them.


It is unclear how many have been affected in some way.

It is likely that the number is relatively small in aggregate.

But it has made for some unhappy lives in the interim. (my case is very sad particularly to me.) 5 minute phone life for a teen is pure purgatory.


Now Apple may come out with a fix for any glitches in the upgrade process as they do.

Some may really need new batteries. The 5 we have may need a new one just the same as it likely already was only 1/2 of its total before this latest unpleasantness.


Anyhow, my fix with a Recovery Factory Restore may work for some as it previously worked for others.

A battery replacement has worked for some.

A battery replacement has not worked for some.

Perhaps an iOS update could help some in the future.


In 3 months most of this will be over with some people so hacked off they don't buy Apple again. Some will have replaced batteries and be happy. iOS updates will continue to roll out and others who have yet to upgrade may perhaps bypass what I view as a buggy 10.1.X roll out.


Happy New Years.

We are all above ground one more year!!!!! rock on.

It is highly illogical to state that IOS 10 had nothing to do with these battery failures.


Manzar, you are new here. Not only did I NOT say it had nothing to do, but I wrote that, IF it did, it is because the batteries were dying or failed the iOS install. From that point on it does not matter. I also said that every week thousands of batteries fail and are replaced under warranty. About 400k$ each months. And each iOS release week, thousands of batteries fail during that window, and owners jump on board accusing the iOS. And sometimes new iOS, the charge stress just friens that defective battery. this happens ALL THE TIME ANY MOBILE BRAND. Do you understand that?


The point is that I argued that base iOS 0s and 1 do not KILL a healthy battery cell, but a poorely manufacturing one could and does die sometimes during a normal reset, or just suddenly. the timing and correlation between iOS 10 release and lots of batteries SSE is irrelevant as the actual issue: some batteries fail.


Did you read iOS 7 battery drain and SSE forums?

Did you read iOS 8 battery drain and SSE forums?

Did you read iOS 9 battery drain and SSE forums?

Did you read Android OS battery drain and SSE forums?

Did you read BB Bold, 10 Z battery drain and SSE forums?


if the answer is no, I recommend you do. None of those users were running iOS 10... What everyone had in common was a hardware defect which was resolved with a hardware replacement.

Jan 2, 2017 7:56 AM in response to paikinator

+1 paikinator. You pretty well summed up my POV as well as the COAs. Reset or Replace/Upgrade. Cheers.


The one point I already iterated is that my poor opinion of all Li Ion technology is the reason I buy xtended warranty and Apple Care regardless of platform (even GPS devices). I think 100$ is cheap relative to the cost of replacing several batteries - plus it covers two iPhone replacements.

Jan 2, 2017 8:09 AM in response to Mjolcresure

How are batteries selected? Lets Assume Microsoft Samsung or Apple Engineering Divisions. xDays before production the teams get together and discuss Power issues, batteries etc. They then consider contenders. the 50$ battery that may work reliably for 300 cycles; the 100$ for 600 cycles, or the 200$ for 100 cycles. Or the NASA 1000$ battery which lasts 8000 cycles. How quick is the production cost? Can suppliers meet demand? The decisions have billions of $ repercussions. The Director must make a call, and a bet, that for the duration of life of that mobile, the battery will perform. Of course there is dissent, programmers may argue with hardware guys, and so on, and the dispute can go all the way to the Chief of Operations, whom may have to make a call. During Steve Jobs' years, he took an OCD approach to every single transistor. Jokingly.


With Samsung, they made a bet that the x battery they chose can meet demand and perform, and it turned out badly. They voted in the quickest production level battery they could secure for an August launch, and skipped extra testing. Yet Samsung engineering has very high standards and they got it badly wrong.


then there was Microsoft with its bad Surface battery batch. years before that, Dell.


The point is that there is more of a human factor going on inside our smartphones that we can imagine, long before us users install iOSes.

Jan 2, 2017 8:21 AM in response to paikinator

Another paradigm re-framing of my argument: let's say that anticipated iOS x mAg drain/hr produces x% of battery fail, then the issue is still the battery. Higher iOS drain should not kill a battery, just discharge it faster. Yet nothing drains nor kills as fast a battery than the Flashlight function. I never use it for that reason : you can feel the battery discharge heating up the battery. It will work a few times then the battery takes a beating... Got a flashlight, ty. Or turn screen brightness to max it is better than running that LED.

Jan 2, 2017 8:29 AM in response to Mjolcresure

I have an iPhone 6s I bought in early November 2015. However my serial is outside of Apple's range of affected phones. Yet, I'm having this problem too. My phone will just die anywhere from 5-30% of remaining battery. The other day I was at 35% and tried to use my camera and the camera screen was slowly going in and out of focus and wouldn't stop. Stopped and restarted the camera but it kept doing it. So I decided to restart the phone, except it wouldn't turn back on!! It gave me to image indicating that I need to charge my phone. Very frustrating!! I came from an android to this phone and I like this phone. But I hope Apple comes up with a fix soon, because I won't have any problem going back to an android. Battery replacement is a bandaid, the problem is in IOS.
