iOS 10.1 Battery drain

i have been having same issue as has my wife. this morning i took my phone of charge after waking up and it drained down to 90% and died. i put in on charge it instantly started turning back on and was on 70% when it did. i charged it up to 80% before breakfast and within about 30 minutes it was back to 10%

I've had this problem daily for the past month - ever since upgrading to 10.1 (and subsequent upgrades made no difference). 40-60% battery tanks unexpectedly to 1% and within 30 seconds shutdown unless I reach power. I've had calls interrupted - and then couldn't call back. I've had this happen listening to music, browsing the news, watching videos - no pattern. I had multiple discussions with Apple who had nothing to recommend - and a refusal to replace the phone or battery (although this must be a software issue since I never had the problem before 10.1 - and I've had the phone for two years). As a result I've been carrying around a battery backup.

Since my phone is now out of the subsidy period I've done something I never thought I'd do - I'm ditching Apple and am setting up my brand new Pixel. A phone that dies without warning is not usable. Disappointing. For now I've completely lost faith in Apple.

Success! My Pokemon Go experiment is working.

Today, all went as normal, battery behaving perfectly.

However, at about 35% or so, it started draining very fast. Soon (15 minutes) it reached 20% and I accordingly switched on low power mode as I normally do.

Then it shot down to 10% and before my very eyes went 9, 8, 7, 6, 5, 4 then shutdown.

Like the old failed battery, I waited 10 minutes, powered it on after a Home and Power button press and back to 4%.

It has now been sitting at 3% for half an hour.

I obviously need to carry out some more testing but it looks like this new, Apple fitted battery is going the same way as the old one after only a month.

The software on my phone is now saying 7% battery wear and has gone down from "Perfect" to "Good"

I am due to visit the Apple reseller next week for my self imposed diagnostic check so let's see how it goes.

and I've had the phone for two years. Unfortunately, if you crossed 700 and upwards to 1000 cycles, the universal technical step is to assume the battery as done, caput, finished, and behaving accordingly. I have read this happening many iOS or Android versions ago, going all the way back to LG Clamshell phones; similar to http://forums.macrumors.com/threads/battery-life-iphone-5.1450993/ Am highly certain that a replacement battery will resolve your issue, and that it is not iOS related in your case, no matter how the sequence started. Other people with sub 12 months of use are a different story, in your case the first troubleshooting step, as in any electrical system, house car, is to replace the worn expired cables, fuses or battery.

Success! My Pokemon Go experiment is working. Been there, done that, got the T-Shirt, and the free Apple replacement battery. At 15-20hrs PG a week, and a dozen+ hard, nasty cycles demand sub 30%, you are wearing the battery very fast. PG related, yes. iOS, nope. Google "Android Pokemon Go drain" = 151,000,000 results.

Oh Bel, are you still here? Bless your cotton socks.

To everyone else. Before upgrading my iPhone 6 to 10.1 my phone was in perfect health. Before 10.1 I was happily getting to the end of the day with 20-40% charge. I have no idea how Apple define their charge cycles. Is it 0-100% or 30-100% or some other measure? And Bel, that was a rhetorical question please don't feel the need to unleash another essay.

What I do know is that immediately after 10.1 my phone started to get very hot while using (even just using Safari), I had rapid discharge and cutouts when charge was showing anything from 20% to 80%. My phone needed to be charged 4-5 times a day and I have had all the problems reported by others. This is all very very simple cause and effect stuff.

Yes, with the new battery, all is currently fine...but I have absolutely no faith in Apple anymore and will wait and see how it goes. My position is also unchanged. No refund from Apple, no more Apple purchases from me. As I say, it's very very simple.

Look like I have got you riled Belisarius.

🙂

No matter what you, Apple or battery school say, my month old battery should not exhibit these symptoms.

I have 28 load cycles.

As I said, I need some more time to test this, it may be a single incident but you can rest assured I will post my results, one way or another.

I am neither Apple saviour nor cynic, I just want my phone and it's battery to work.

Adrian.

As an addendum, my battery has been sitting at 3% now for an hour, no shutdowns.

This is exactly the same behaviour as on my battery which was replaced under recall.

Also, if Pokemon go kills batteries take it out of the app store.

Where is Apple in all this?

Adrian.

Adrian, am one of the few users whom has provided Apple App feedback and witnessed a few bad ones/scam being removed. It really varies with user feedback. I am unsure how likely Android or iOS PG hunters like you, scaling new levels every week, seeking those Zapdos Pokemonsare ready to provide poor feedback on an app that provides such free level of brain dopamine. Where I am it also is a recent phenomenon, arriving only months ago. But I read about it frying Android batteries in Asia a year ago when first launched as a beta test. Also there is economics, but they are outside the forum scope.

"No refund from Apple, no more Apple purchases from me. As I say, it's very very simple." If I recall you paid 120 British pounds, many users paid 80$, close to me the replacement cost is less than half what you paid. I think that feedback that batteries should be easier to replace at an authorized center, at a more universal, lower price, is excellent feedback to provide Apple. Already provided mine.

No I actually paid £69 to replace the battery at a UK Apple store. It did however include a 60 mile round trip to the closest store and 5 hours out of my Sunday...not happy.

I've spent well over £10,000 on Apple products since purchasing my first macbook pro in 2008. I've also been a great ambassador for Apple. I won't now be buying a macbook pro to replace that one as planned this summer. For the sake of £69 Apple have just shot themselves in the foot (admittedly they do have very big feet though).

If a friend of yours had just taken £69 from you, it doesn't matter if you've had a great friendship in the past you expect your money back and an apology. A reasonable metaphor I think.

This will likely be my last post, number four, and I will stop following this thread. Too many posts! And, except for Belisarius, all saying roughly the same thing - that things were fine before iOS 10.1.1 (or 10.1 or 10.2) and that, thereafter, things were no longer fine, that batteries or battery indicators showed massive depletion, sometimes shutting down sometimes not, that plugging in the iPhone immediately caused the battery and/or the battery indicator to return to its previous level, that often the iPhone would function for 30 minutes to an hour or more at 4% or 1% battery indicator, and similar complaints.

Most of us have concluded, using logic as well as our experiences, that, when most if not all things have not changed BUT FOR one factor (in this case downloading iOS 10.1.1), and a different result ensues, that the one factor that has changed is likely the principal, primary if not sole cause of the different result. Most who have posted have noted that our iPhones were working fine before downloading iOS 10.1.1 but that immediately or soon thereafter these drainage problems emerged. Some of us have had the problem on almost new phones; others on phones a year old, others still on older phones. Some of us seem to have cycles less than 200, others like myself, at least according to one battery app, showing cycles at 325 or thereabouts, and still others with much more cycles (not that I claim to understand the technologies involved here). While a few, and it appears to be a handful, report that their batteries stopped suddenly draining after installing a replacement battery, one just reported the problem resumed. And the number with replacement batteries here is very small, the time period after installing it very short.

So, yes, I am among those who are convinced that Apple's iOS 10.1.1 (and variations) is primarily to blame for our battery drainage problems. I'm not even sure whether the battery is draining or the indicator is misreading, as I have had the indicator remain at 100% for over an hour while I have been intensively using my old iPhone 5 (not my principal concern here which is my iPhone 6 Plus), although it appears the actual battery is being depleted. Do I reject Belisarius' repeated (and I do say repeated) assertions that the battery is primarily the culprit (or at least that is my understanding of his contentions)? Yes. Do I say the battery and its quality are irrelevant to the problem? No. And certainly, despite the extent of this problem, it would appear that the majority of iPhone users who have downloaded iOS 10.1.1 are not experiencing our problems.

At the end of the day, I am convinced this is not simply a case of a limited but extensive number of iPhone users having downloaded iOS 10.1.1 with already declining if not failing batteries. Interestingly, AppleCare tested my iOS 6 Plus battery the other day over the phone and said it was Good. (I will visit its Genius Bar next Monday.) I am still under warranty so if the battery is the problem, Apple should replace it. But most in that situation say Apple has refused. We shall see.

Thank you all for sharing your experiences. And fortunately Forbes has picked up on this story. I hope Apple is aware of the extent of discontent and that it addresses a fix in iOS 10.2.1 even if news reports are questioning whether that will happen.

I think you are misrepresenting the problem, and stated facts. Can try portraying them as arguments, but facts are facts. Nowhere has anyone mixed a 6 months old issue with 24 months feedback. All he has to do is seek and answer questions such as, does one expect batteries to last infinitely? If not, how long, how many cycles.. 700.. 1000 2,100 aero.. 8000 space grade. How would an old, or tired 700-1000 cycled battery behave.. And how come are the majority of users "not experiencing our problems" - his words- running iOS 10.2.. are their 700-1000 cycled batteries expected go on towards OS 20..?.. Can I blame the next OS in advance because my 6S has 350 cycles, and will time 700 with the next iterations.. Not at all, will replace the battery or the phone.

It is absolute gibrish and scientific nonsense to attribute all failures, especially on tired, done or old hardware, exclusively on OS. Impossible. And those with new phones, they are getting support differently. And, batch by batch, some users were helped by a recall, others by advanced Apple support, battery or phone replacement. Some users had code errors and Genius Bar firmware reset resolved it.

If some people wish to speculate on OS coding, no objection, but it is outside Forum terms of reference, many such posts have been removed. There was a link above on iPhone 5's 2012, users complaining of exact similar issues. Or Android battery failure/drain links exceeding 150 millions. That is why I do not comment on OS coding, and glad to witness so many whom resolved it. All we can do is focus on the tangible, the resolvable, the controllable variables. Fact is, all whom replaced old batteries returned to claim resolution. Fact is, batteries die, and have a finite life. How fast depends on case by case, 12 18 or 36 months.. Fact is, when they fail, they fail with universally similar symptoms, regardless of system. Fact is, with hundreds of millions of phones out there, each OS release out there coincides with so many just reaching end of life, and does not pass the new calibrations.

I have a phone like that. It is not iOS, but your battery is getting old. after a few years, it starts to degrade. You can have it replaced byApple Support. iPhone 5 is almost 5 years old. Again, I have the same problem.

I have the same problem on my iPhone 6 Plus too after updated to iOS 10.1.1.

The battery becomes acting so weird when the battery is down below 50%~60%, then it would suddenly pop out the notification of low power and shows up the remain power of 20%. If I continue use it, it's amazing that 20% of power can stand for a while and then goes off suddently without showing the decrease percentage. If I choose to charge it, the power start to charge from 50% instand of 20%. It seems like that all battery detection is screw up.
