iOS 10.1 Battery drain

"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.

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.

+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.

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.

For the record paikinator, you confuse us a bit with your iPhone 5. 🙂😕 At some point you wrote it may have been 1/2 life. If so, may I ask, what were you expecting out of it.. You read first hand the Battery University charts. Below 50% a Li Ion cell dies exponentially fast...

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.

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.

Your arguments are all wet. There's enough evidence to prove the OTA installs of 10.1.1 altered the phones in a manner that rapidly destroys a good battery. On hundreds of thousands of phone, not limited as you assert. Those phones updated via hard wire do not exhibit the phenomenon. Your techno babble is worthless.

I found that when my daughters iPhone 5 started dying, it wouldn't power back on using the small wall wart all of the time. Sometimes I could power it back up using the computer. Using the iPad wall wart did the trick too.

Belisarius.

I was talking mostly about duration of run Time. It was more the sense that when the phone was new it would last about 3 days sitting on standby. Now it lasts about 1/2 that time.

I think I will give Apple a call and see what they say about my battery with their diagnostic tools for clarification.

Should be interesting. Excited about finding out what they say.

Hi Apple Yoda,

I agree with you! So tired of the endless chatter on this thread too! I did a factory reset and the problem resumed after a day. I wouldn't suggest it. It is an OS problem. I did 2 restores, one at the Apple Store and one with an Apple support member on Twitter, finally spoke with a Apple Supervisor where he walked me through a factory reset. Nothing worked. Hoping Apple comes up with a solution soon! Good luck!

Paikinator, iPhone 5 battery warranty was extended to 3 years on affected models, from purchase date. Worth a try if yours are affected :

'"Enough evidence" and OTA? Hmm sure aliens did not do it? What about wired updateswith which people had issues..

So your premises? 0. Assumptions? You list 0 factors analysis? 0. Hypothesis? 0 Conclusions? 0 theory? 0. No methodology no science. The letters you grpup together provide 0 value. Therefore if you have 0 to contribute , why post?

Flat tire? Road chips? Poor battery? Get over it. Are you born after 1984 expecting someone to always solve lifes small stuff?how about you get a new battery, then come back and let us know. At least that is a solid trial and method...

Sylvia, iPhone battery forums go back 9 years. Some warranty programs are 3 years now for select batches. I hope that you are not considering waiting more than a year.

You are welcome to read 1000 pages worth of community discussions since iPhone 5. I have nevet seen an user with abrupt recurring shutdowns EVER return to post that her/his issue was resolved by an IOS update. Hardware replacement, yes.

Goid luck waiting for a software solution.
