iOS 10.1 Battery drain

"Still have my original iPhone (using it, now, as bedside alarm clock. on its charging base) and battery on that one died after 4-5 years (but I wasn't charging/recharging it anymore. believe it even stayed totally discharged for days, which definitely doesn't do the battery any good)"

Exactly. Battery university explains what happens with Li-Ion cells if left void- they just die. And why they must always be shipped with a partial charge (usually half).

Hi Belisarius, I take onboard all of your information and agree that battery technology has not changed much since the discovery of the so-called "Baghdad Battery".

🙂

Be that as it may, I have had had experience of iPhones in my household and workplace ranging from the original to now a 7 which Santa brought my daughter, just in the nick of time as her 5 was severely affected after the IOS 10 install.

Now, Santa was prepared to take the hit on the 5, it was a number of years old, but not on the 6, the 6s and the numerous others he has encountered over the past few months.

I have never seen battery drain like this on any IOS.

What angers me is that if this is the case, why are Apple not commenting to this effect?

Why did they release diagnostic tools in 10.2 if there is nothing wrong?

I cannot be sure but I know that a lot of background data mining/location aware advertising/selling is happening in smartphones nowadays.

As soon as I upgraded to IOS 10, I noticed that several of the apps, e.g. Pokemon Go and Facebook were not closing when I swiped them away. Sometimes the message at the bottom of the screen would still be there, even after a reboot of the phone. They all said "Based on your current location".

I even opened up a discussion on this as I thought it was draining my battery even then, 20th November [Edit, actually, just looked and it was 22nd September]:

Pokemon Go, iPhone 6s message below Home Screen.

After talking to Apple, one of the tech's said it was normal, yet one or two updates down the line, I no longer get these "half-open" app messages on my phone, so Apple changed something!

Also after IOS 10, a few Countries are reporting their location services are not updating their local weather, again another thread I raised:

iPhone 6 on IOS 10, local weather not working.

Now, could it be Apple's location services which are the lifeblood of a smartphone nowadays in terms of revenue for advertising is not working properly and causing excessive tries at finding locations?

It is this secrecy and non-disclosure that can seriously damage a Company's reputation, because Apple do not come forwards one way or another this starts growing arms and legs.

Fine, my battery is worn out, let me know and I will replace it.

But don't wait until a Chinese Consumer association makes enough noise then do something about it.

How many people have gone sheep-like to the Apple store and replaced their batteries I wonder?

Adrian.

Evening Adrian

We need to discriminate two very separate, but real issues: OS drain- which can be app and usage related. Poor optimized apps, incompatibility, constant pinging, etc. And yet, even the Geolocator and antenna seeking will constantly swing any phone in a high power consumption more. Everything you wrote about the apps is correct.

Above and beyond iOS breaking in, the second issue discussed here is the erratic functionality. i.e. 30-1-30, 80% shuts down, etc. , random shutdown and widely abnormal functionality is a separate. This is the most severe for the user, and the most indicative of some hardware issue. Just drain alone is not sufficient, unless going from 100-0 in just a few hours.

A good test for everyone's phone is to do as Apple recommends: clean install and just watch the iPhone for a day, without Appls. If normal functionality, than it isolates apps as the issue. BTW, this why I always do clean installs.

What angers me is that if this is the case, why are Apple not commenting to this effect?

I cannot comment as to Apple's position. But, as I wrote in previous posts, if a few tens of thousands (out of hundreds of millions) of iPhones experience issues weekly, as Arstechnica wrote, it may be the modern reality of owning a smartphone and still very minor. Case by case, Apple has been known to issue recalls. E.G. 6S recently, or the 200 million USD MBP NVIDIA settlement in 2012- every affected user got a new logicboard. But Should Apple be expected to comment on normal industrial failure?

Why did they release diagnostic tools in 10.2 if there is nothing wrong?

Perhaps I can re-phrase your question, why did Apple wait until 10.2 to ever release a diagnostic tool? Or why is the battery health not visible/available to the owner? Why did Apple just remove the leftover hrs/time in Sierra? Do you remember the days when logicboards were basic, 2003, and in 2013, all HQ boards now have onboard diagnostics? RMAs cost a lot of money to manufacturers.

And why do users not have the option to opt-out an upgrade? I keep having to turn down iOS 10 several times a week...

Anticipating some design quirks, personally I skipped Sierra and still have my battery life managed by 3d party apps on my Mac. I also reversed iOS 10 to 9 as I found the new 10 interface too dangerous when driving and music kicking in via Bluetooth, unable to stop it with one finger (itune window now has to be swiped).

To answer you earlier comment on removable battery, that is done. The industry spent hundreds of millions repairing water damage to phones. Moisture, humidity summertime, etc. Casing in the phone waterproofs it. The real issue, in my opinion, is the inherent limitation of the Li Ion technology.

How many people have gone sheep-like to the Apple store and replaced their batteries I wonder?

Most visits at any Apple store, at the genius bars there are several macs and iPhone users- you can see them lined up. Some are software issues, others, resets. Lots of user-inflicted, e.g. cracked screen, especially in the newer, larger phones.

I also know iPhone 4 users with functional phones, as they are locked in an older iOS, no upgrade prompts.

Can an iOS ruin an iPhone? I do not know if an iOS, have wrecked one phone accidentally leaving the flashlight on in the pocket, and only realizing it when it overheated. If background Apps place a great strain on a sensitive battery, then yes, those cells would fails the rapid cycle and the management controller moves in containment mode. But the reason several users have had their issue resolved with a new battery- yet same apps and image- is because the previous one did not survive the demand.

Back to cars, winter in Canada is an amazing time to discover that usage and condition of battery varies with demand and, lately, car technology. The more technology, the more owners need to keep them plugged.

How many people gone to stores? No idea. Most replacement statistics are online, done by industry gurus, but only Apple knows the week by week warranty replacement status...

I have noticed in the last few days that my location services icon is almost always on despite me not having any apps open that may be utilizing them (i.e. they have been swiped closed). That, compounded by what others have stated about apps seemingly still operating despite being closed, is leading me to believe that maybe it is a bug related to location services where it is using way more battery than it is supposed to. I have noticed that my phone shuts down quite often when I am using apps like Snapchat, twitter, instagram, pokemon go, etc that use geolocation. At this point I'm maybe getting a minute and a half use in those apps before my phone shuts down. I have turned off location services in my settings and am going to attempt to use my phone and see if it still shuts down.

I have noticed in the last few days that my location services icon is almost always on despite me not having any apps open that may be utilizing them

I always have it off unless navigating. If not, x2 drain, easily. Also, each time a user clicks "I Agree", he she agree to all sorts of new App and InterApp interface. How do we know that Snapchat twitter and instagram do not also sync with each other in order to better sell you ads? Since I do not own them no issue. I avoid them precisely as they want to take over one's private sphere and move it in the cloud, and then sell the constant connectivity as the sole way of using a smartphone. I cannot conceive of that. The web is now web 2.0, very much power hungry. Multi new platform technologies also rely on the geolocation to define how they even interact with you, from online stores showing local geographic prices, to pictures of favorite restaurants popping up live. Do they burn power? You bet.

If no reset/restore works, likely defective unit. Apple can assist with that.

https://www.extremetech.com/mobile/241772-google-nexus-pixel-devices-shutting-ba ttery-drained

The new Google Pixel is behaving identically for a small number of owners- including shutting down at 30%. Since Google Pixel does not use iOS, that rules out software.

In an economy of volume, these battery cells and controllers are made by common manufacturers for all brands. The same way Corning makes Gorilla glass for everyone, Toshiba and Samsung SSD's etc.

Cool, great for you but not relevant to the topic at hand. I am fine with the role and influence these apps have in my life, so no issue there.

Back to the point, turning off location services didn't really do much for me. I was able to get a little more use out of it, but it still ended up shutting down at around 84%.

The Battery is the entire issue.

The only solution is that the Batteries must be replaced. There is simply no other possible answer and therefore everything else is mere flailing around by a bunch of nincompoops and ignoramus' who won't believe him or take his advice to spend money on a "Apple" only battery replacement.

[~Belisarius

Thank you for this splendid example of poor critical thinking. First, you build strawman arguments- words myself or no one else said, then you take them apart. It is highly indicative of very poor deductive logic.]

I never did say you used those exact words. No strawman at all…. neither is this any example of poor critical thinking on my part but thanks for trying to point out a flaw in my person.

My comment is paraphrasing the gist of your entire arguments since you started posting. A simple distillation of what you have posted since page 66 of the 79 pages thus far.

i.e. the battery is the issue causing this; you need to replace the battery to solve this issue

[NOWHERE HERE ONE HAS ADVISED TO SPEND MONEY as a solution- in fact, most iPhone 6s owners are covered by warranty still;]

De Facto pushing first for people to get a new battery as the primary solution is telling people to spend money. People with iphone 5’s 5s’s 6, 6plus’ are all suffering from this issue and yet the lone solution presented is a battery upgrade. Further is the insinuation that people are daft if they don’t hit the genius bar and get their batteries replaced.

Of course owners who still are under warranty have greater options for getting a phone or a new battery. It is widely known that 6S owners are covered so this point adds nothing to the discussion. All non-6S owners have also been encouraged to get batteries as the primary solution. Commentary was not specific to 6s owners in other words. So that would necessitate spending money to replace their batteries by a large number of people on this thread. Fact.

Pounding home the point of the need to swap out batteries in at least 10 postings ellucidates the stance of Belisarius. Further in the postings is the suggestion that to not replace the battery is wasting time. There was a claim of being here forums despite not personally experiencing the issue to help forum members “better utilize their time” by “guiding” them to battery replacement.

[nor has anyone called the audience names as you just did.]

Merely more paraphrasing to show the intent of Bellisarius’ postings. The view of those who don’t agree with the position taken is to denigrate them as illogical and incapable of thinking. Hence nincompoops and ignoramus’

[Also, no one has argued that the battery alone is at fault.]

Note: There was a Beisarius and a ~Belisarius.

Same person? 2 user accounts for the same person? I don’t know.

Beisarius - First post was page 66. Suggested Apple would be coming up with a fix soon.

Page 69

The first suggestion by Beisarius is to go the genius bar and get a new phone. (Nearest one for me is 2 1/2 hours away) Great and expensive option for most people.Especially given that this could simply be an update issue.

Also suggest that users are at fault for running “energivore” apps or social media.

Pretty much every post beyond page 69 is an intensifying effort to bring up the issue about batteries being at fault in some manner. So much for the idea that Apple will come up with a fix or skip calling apple and run to the genius bar to get your new phone. Now one needs to run to the genius bar and get a new battery strait away.

There is a questioning as to why people are trying to resolve an issue that is not resolveable by consumers….

Most of what is said in the next 10 pages of commentary is about batteries, battery controllers, battery drain over multiple generations of phones proving that the battery is the issue, firmware updates hosing the batteries, OS upgrades hosing the batteries. Lots of crummy analogies about batteries.

Over the last 10 pagesdiscussion by ~Belisarius has revolved around batteries alone with the claim of being on these forums to help guide people to better utilize their time by getting a battery replacement.

[But that, once all initial steps concluded, i.e. Apple Call, Hard factory reset, etc, the battery is the only next logical step, and most likely to solve the issue.]

There is no mention by Belisarius about doing a reset as a means of solving the issue.

Others have posted about success with resets before ~Belisarius started commenting. And after those factory resets the battery began functioning again without spontaneous crashes thus indicating that there might not be an actual battery issue in some cases.

[It already has for countless of forum posters since the launch of the initial iPhone. Yes, for 9 years some peple have battery issues and had them resolved. And each forum level, each year, someone thretened and blamed Apple. We all laughed..]

There is no dispute that people having battery issues have had them resolved. The discussion has been whether the issue this time is an actual battery issue or not. You say yes it seems, I say perhaps for some people the battery may be the problem, but perhaps there could be other causes. It is too early to tell and too complicated for a one-size fits all solution. For some a battery swap may work, for some a factory reset may work, for some an iOS fix may be in the offing.

Why?

Success with a battery swapis only for some. For others a battery swap has not helped. The issues are complicated and varied.

Threatening and blaming Apple?

People have a right to be upset when their expensive phones stop being functional after an update. They also have a right to feel the blame lies with Apple. They own Apple phones developed by Apple running software developed by Apple. Threatened Apple? Really?

Most people seem to have said they may seek another phone. That is a choice not a threat.

[Another lapse in judgment: your not realizing that SPENDING MONEY ON THE BATTERY IS 100% RISK FREE. Since Apple guarantees it working or full refund. 100$. Vs 1100$ for a new working phone.]

Key word… “spending money” on a Battery. If some find a solution without spending money because of swapping the battery, then they have a better solution available.

Has nothing to do with judgement or not on my part, but you keep wanting to make this about me and my brain processes.

There are other solutions that work sometimes. And perhaps a software update will provide a solution for others in the future. Perhaps the 10.2 update already helps those who do a factory reset where 10.1.1 provided no such help. And perhaps some have a true battery issue as you propose.

But even when those who choose to swap the battery do so, perhaps the fix is not actually the battery, but rather something about the reboot and reset process which clears out whatever got glitched out when 10.1.1 was installed.

Thus perhaps not a Battery issue at all, but people had to spend on a battery regardless. Seems like it is hard to say at this point what caused the problem and what ultimately is responsible for fixing it. Software, OS, Hardware, battery, controller.

[What do you have to say to that? Because no one will fix for free those 10x e-6 defective units out there or 40 000 or so units a year. If you have Apple Care, sure. If not, Apple employees are fairly generous at buying back your partially working phone and discounting a new phone.]

All of this costs money when the problem could simply be an OS update issue. Being cavalier with other peoples money is easy.

[So yes, with academics and reading, and learning, it takes seconds to return to this page and call out anger mongering, negativity, blame finger pointing and no constructive solution option.]

My solution is working on my 5.

IHIP699 solution worked on his iPhone posted well before Belisarius came to this forum.

Those ARE constructive solutions.

Repeating for 10 pages that people need to swap out their batteries seems to be browbeating others. The battery swap solution has been noted by others prior to any post by Belisarius. Likewise battery swap not working or partially working has been posted.

[Since you blame Apple in your entries, yes, your solution can de dissected as nagging finger pointing.]

Nonsense. The solution still is solution perhaps for those who have a 5.

Simply noting that OS’s can lead to various bugs has been well documented and is not nagging finger pointing or blaming Apple. Apples phones and their software are made by Apple. If something goes buggy with an update who should the blame be assigned to, the buyer?

Anyhow, these are complicated systems and I don’t waste time assigning blame. I have said so in most of what I post here and elsewhere. Trying to assign such sentiments to me is misguided and your own issue not mine.

And since Apple corrects bugs frequently by issuing updates there seems a de facto acknowledgement that bugs can cause various issues and updates can resolve such issues. That is reality… not blame.

So No Fingerpointing. My ongoing work for a solution may work for others perhaps.

[As for commenting on Apple batteries, this is a serious mistep on your behalf. Anyone putting non-Apple batteries in their phones not only are unlikely to get them to work, but are nulifying any warranty and more likely to fry their entire phone.]

Commenting of the batteries is a mistep???

Not sure what the meaning is about, but perhaps this reference is to Batteries plus?

Well since most phones affected are out of warranty “voiding the warranty” is impossible. If the phone is under warranty you simply replace the battery for free.

As to Batteries being installed by such large businesses whose prime function is selling batteries, I believe that hundreds of thousands of iPhone owners have done so at large repair shops with great success. Since they offer a warranty for 6 months, it seems unlikely that Batteries Plus would go to all of that effort of putting the batteries into the iPhones if the batteries don’t work at allor indeeddestroy their clients iPhones as is your assertion.

Anyhow, do you have a reason to think the Batteries used by Batteries plus are bad? Have any data to say a Batteries Plus battery won’t work in the phone or will fry it? In fact aren’t many 3^rd party batteries manufactured by the same factories on the same assembly lines as Apple’s own batteries?

[The advie offered, and my Christmas time generosity gift for you, is to save people's time.]

A redundant postsarenot a Gift. Badgering people on a forum when oneisn’t even dealing with the issue being discussed oneself and berating the motivations and intelligence of those who are coming for answers and participating in the discussion is a waste of other peoples time. Feeling the need to post 25% of the posts on roughly 13 and counting pages doesn’t help a discussion group. But to each his own I suppose. Keep posting. It is your time.

[ The sequence is as fol:

- Factory reset, with or without Apple Sr support

- Risk free battery replacement and trial, paid or under Apple Care (no cost)]

Nice to see you finally mention Factory Reset first finally.

Others including myself have been posting about this as a possiblesolution many of pages before Belisarius got here. Nice to see you finally change your mind .

Funny that your first solution sequence based on your posts was different.

1. Apple will come up with a fix pretty soon so don’t rag on Apple

2. Don’t call apple about it go to a genius bar and get a new phone.

3. get a new battery cause that is what is causing the problem of apparent rapid battery depletion and spontaneaous shutdowns.

4. Get a new battery cause faulty controllers, firmware, etc caused the battery to fail during the stressful update.

5. And now below… you will need a new phone because this particular phone revealed what a crummy phone you have had for the 3-4 years. hahahahaha

[If these fail, guess what? The phone maybe the issue- for whatever reason. 40 000 a year/240 million, you drew the lotto..]

????? Not helpful.

[Any comments? What is your advice? Besides whinning, blaming Apple or accusing forum members for defending Apple with neutral facts?]

Yep.

I have posted 6 updates about my experience and probably will post some more over the next few weeks as my experience with this real issue evolves.

No whinning. Speaking ones mind and whinning are not equivalent.

No blaming Apple. Stating how things happen is reality

But I will definitely call out members who badger other people on the forums and are not contributing significantly to the discussion. I have 6 updates to my experience.

~Belisarius~ wrote:

Agree. For us who are experiencing this is very frustrating indeed with no real solution in sight.

The problem is your approach and faulty approach, poor methodology and reality perception. Do you reac the same to a tire flat, or poor car battery? Many users have already have thei fixed- and other forums mention that.

So there you go with attacking the person their thinking and logic.

Really? Reality perception?

IHIP699 actually did a factory reset fix long before you began posting on this thread.

Guess you wouldn't be aware of that though.

[Just to make sure, are you Anglophone, read/write? Not using Google translate when reading and replying? Because by resetting or reversing the iOS, you did the very first thing I recommended. And it may have worked.]

First thing I saw you recommend was basically ….Apple will fix it.

Second thing I saw was … don’t call Apple go get a new phone.
After that is was go get a new battery and you have been stuck on that for 10 pages and mounting. As of page 80 you seem to have switched, but there is a record of what you say in text your realize of course. Point me to your 3 step process within the body of text on this thread.

Another dicothomy, the best one, is spending countless hours staring at your phone(s). Personally I value my time at 300-500$/hour. But let's assume you value yours at... 100 or even 50$. I am not sure my advice would have cost you money, you actions surely do- rawly might we add, valuable holiday time - and money- while providing here entertainment on critical thinking what not to do.

I can mind my own actions thank you. We each do what we do and are what we are in this life.

And how much time have you spent typing that people need to just go get a battery over and over? I think you have far more posts on this particular thread than I do. You seem to need to respond to more and more people who are posting to impart your “Wisdom” on them. Are you getting your moneys worth this holiday season? How many people have your words convinced to actually get a battery and what was that worth to you?

It seems like you should know that resetting a phone is largely a spotty affair in terms of actual attention to be paid to it. One doesn’t spend much time “staring at the phone”, but perhaps you do factory resets differently. To each his own if this means you think you need to spend countless hours staring at your phone while it updates.

Anyhow you do provide countless hours of entertainment I like typing on the internet with people. I especially like engaging folks such as yourself. Call it an impulsion. Don’t get to do it much in my real life so the holidays give me a chance to spend more time in front of the screen.

"Its the Battery stupid" Definitely sorry to hear you feel intellectually inferior, or that critical thinking has that effect.

Hahaha… that is a funny deflection and twisting of words. Do you do that a lot? You like the words “critical thinking” a lot don’t you?

What has critical thinking to do with repeating the same “go get a battery” mantra over and over? What does critical thinking have to do with passive aggressivity you seem to have for anyone who doesn’t agree with what you type? Are you capable of posting without attempting to insult people about their intelligence in some fashion?

Do you feel questioning the intelligence of others makes you more intelligent?

However, easy peezy example. Since I never wrote that- nor claimed it, you did a Strawman Fallacy, an error in thinking.

And yet I never said you did write that or claimed you wrote it.

What I typed is a simple distillation of your mantra over the last 10 pages into a basic phrase. I figured that was would be painfully obvious and simple to understand. Didn’t understand that? Are you kidding? You must be joking with your sumptuous use of the “Dread” Strawman Fallacy thingy

you omitted my first step (resets/restore), focused, cheaply, on the money argument and then attacked it.

What first step? Where? What page of the thread?

Was your first step in something which was deleted perchance.

IHHP699 did a restore. I saw that way way back.

I did a restore before you started posting and posted about it with a couple of updates before the first post I see of yours.

As far as I can see you have no mention of “First Step” RESET/Restore. And what exactly is it you mean by reset in regards to the iPhone and this issue? Reset isn't the same thing as a rescue factory restore so it doesn't get rid of everything on the phone like a rescue mode Factory Restore? So I have been told anyhow

focused, cheaply, on the money argument and then attacked it.

The money thing would be far from cheap and in fact expensive if you are telling people they should take their phone to have the battery replaced when they in fact don’t need to. A Restore can work now.

You also attributed language not used in our posts- another Strawman.

No I didn’t. I did a short ineloquent synopsis of your basic advice in trite phrases. I never said you said it. I am not refuting a point you didn’t make. You spent 10 pages trying to convince people in all kinds of ways that the real issue is the battery which needs to be replaced. All I was saying is that you might be partially right and that there may be a bunch of other things that are right as well.

Where I disagree with you is you thinking this is mostly a battery issue. It maybe or maybe not. It seems like factory Restores to 10.2 work and I have the idea of people running out and wasting money on a new battery if in fact another solution will work. You now in pages 79 and 80 seem to be saying restore too so that is fine. Before you weren't as far as I can see.

And I am not misrepresenting your position that basically you think people need to replace their batteries.

Misrepresenting what you say might be a Strawman, but you spend 10 pages telling people to get a battery.

Would not pass in Critical thinking 101 (usually philosophy classes), legal court, and so on. I understand these technical socratian argument may exceed your formation

So here we go with the “paikinator” is a simpleton ploy. Old enough ploy to have come from Socrates and yet it doesn’t make you any more than you are or me any less than I am.

I understand these technical socratian argument may exceed your formation

Except socratic method as such should not be above utility for anybody… that is the point of the Socratic Method. It doesn’t rely on intelligence of any kind. Even the most simple of people should be able to lead people to understand the logic of what the are saying through questioning. The only problem would come if there were some flaw or inconsistency in what one is saying to begin with which would reveal itself in the questioner.

Beside you haven’t used any socratic anything up to this point. You have been telling people things which is not the same as Socratic questioning.

, but the three step solution I recommended (Reset, Replace Battery, Replace iPhone), is not at all changed.

From what I can tell there was no 3 step solution until the last couple of pages. You began posting on pg 66 from what I could see and the first post was basically “Apple will fix it”.

Next on Page 69 you advised skipping calling Apple and take the phone to the genius bar for some sort of replacement? Saw no mention of a 3 step solution. You have brought that up more recently in the last page or so, but it has been pg 69-79 of replace the battery talk before that.

Saying go to the genius bar and get your battery replaced doesn’t count as a 3 step plan either. Can you perhaps point the page out where those steps you stated reside? Perhaps I may have missed it.

But those 10 pages I looked at reverberate with the refrains of “replace the battery” “the battery is the real problem” the “controller of the battery is the problem” “the firmware” is causing the battery failure, the upgrade overtaxed and exposed the bad hardware and on and on…….

Narcissism is when someone views the universe through their own, exclusive lense.

OK so now you are attempting to label me yet again? Really. Doesn’t that get tiresome for you? You are consistent in attempting to insult people in ways you think make you seem to have higher brain power. But such things say more about the person attempting to pin a label than they do about the pin-ee. And they don’t actually strengthen a person point of discourse.

You just dish unfounded jibrish about Apple, the iOS, ignore mounting evidence from users whom a battery replacement fixed their issue, this is what we would call cognitive dissonance and attribution error. Worse, if you spend too many hours staring at that phone, watch out, it might start boiling…

What jibrish about Apple?

What about iOS.. now you have me intrigued about my seedy commentary about iOS. Do let me in on the secret.

I haven’t ignored anything. In fact I have said that the battery may play a role in this current issue and has played a role in problems historically. How is that Ignoring evidence?

And where is your “MOUNTING” evidence exactly?

From what I can tell, when people changed their battery when they had 10.1.1 installed, the batteries even newly installed seemed to underperform. And some people still had the rapid drain and shutoff issue. With 10.2 and a new Battery the issue seems to be better. But that doesn't exclusively point to a Battery Issue.

When I did a factory install with 10.1.1 the problem with my daughters phone persisted, when I upgraded to 10.2 they persisted and worsened. However, when I did a rescue factory install of 10.2 the problem seems to have disappeared.

So it seems that 10.1.1 may have had a problem of some sort. And upgrading to 10.2 dragged some of the problem along with it. The system wasn't entirely cleared out perhaps.

But people who have done the 10.2 Factory Installs have had success.

Oddly… if I had followed your advice and purchased a battery... with a 10.2 reinstall with a new battery would have appeared to fix the issue as well.

So although peoples battery swaps are helping some people.... Factory Reinstalls are also helping people if the factory reinstall involves a fresh install of 10.2.

Now Apple has made it impossible to roll back from 10.2 which would seem to indicate some sort of flaw that Apple might not wish for people to roll back to. Could be many many issues. Including a big security problem they haven’t talked about yet.

This forum has been fixing people's various mobile issues for years,and battery, long before you realized that your battery was draining too fast and started blaming Apple.

And I have commented on the forums before... going on 11 years now.

Fix your issues, and enjoy the holiday. Then agaion some like staring at standby phones.…

My issue was fixed by a Factory Restore to the Upgraded OS. That takes almost no staring at a phone to do. The genius bar is 2 1/2 - 3 hours away on snowy roads. Batteries Plus is 2 miles away. They use Rayovacs.

My fix had nothing to do with a battery. I will keep the forums posted. Enjoy the rest of your holidays as well. My best wishes to you and your family!!!

There is an old adage " Do not argue with fools or they will bring you down to their level, and beat you with experience."

You have three options - Reset- Replace Battery- Replace phone. Simple. Quantifiable. Only dependent variables you can control. The 20 min a day taken to reply here is for the benefit for those that have listened- and quite a few did so very well, not those unable to.

Did not bother reading your entire charade foe the first adage I just mentioned. 3 things you can do. Choosing a 4th- winning - or a 5th- blaming - do zero for your situation.

"Back to the point, turning off location services didn't really do much for me. I was able to get a little more use out of it, but it still ended up shutting down at around 84%."

Did you also do a clean reset-install and clean phone usage, such as iMessage and calling? If so, and it still does it, you likely have a defective phone, battery or whatever inside it. Genius Bar will swap it - or they usually do.

when someone takes onsees and toosies isolated incidents, and they project them as a law, we call that a faulty generalization. So "when people" and "some people" (Paikinato, p 80) have issues, it means nothing- argumentatively or scientifically or statistically speaking. What we do now is that nearly 500 million iphones 6 6S and 7 have been sold since Jan 2015, and, every week, Apple does replace a specific number for various issues boiling down to symptoms very similar to those many users describe: unexpected shutdown, rapid drain etc. could be 20,000 and up to 50,000 worldwide, weekly- to keep in number with the max RMA ratio.

If my phone was very precious, and I needed it working, Apple Sr support once fedexed me a replacement and I put the defective one in the case, and returned it. That is another real solution. But seems to me your approach has more to do with your avoiding the Genius Bar than everything else that you wrote. Hence you anchored the entire thinking around troubleshooting around geography as yourself, personally, live to so far away from one.

Calling Apple support has been one of the first steps in initial posts. With the caveat that - A. Apple Sr Support will make users do a reset, (which most people do) and that, B, if that is done and the phone still acts up, 9/10 they will offer a Genius Bar appointment for further troubleshooting. Hence why calling them is senseless if the phone is indeed beyond normal resolution steps. Logical, clear, everyone knows that except paikinator.

1/10 magic words result in the Fedex shipping a new phone. That is a case by case basis and at their own top tier decision and discretion.

Yes, I took my phone to the Apple Store, they ran diagnostics and I had 90%+ remaining battery health, and they did a clean install of iOS 10.1.1 back in November. Now, they are telling me I only have 30% battery health and that I need to have it replaced (I am no longer under warranty) a month and a half later. So this was not a gradual degradation of my battery health. I do not accept your notion that this is an anomaly unrelated to iOS, so please don't come at me with some long winded explanation as to why you believe I am wrong. I respectfully agree to disagree.

Thank you for validating that what I wrote to you, likely having a defective battery, is indeed so. And before commenting further all I can do is guide you to the Arstechnica article

And Bettery University. Between these two, it is quite cogently argued that there is nothing special about battery failure, it is the normal modus operandi today (Arstechnica).

the questions I have for you is: A- Have you ever anticipated that Li Ion batteries may fail anytime? and

B- How do you expect that failure to manifest itself?

So all we know is that a defective battery went from 90% in November to 30% 60 days later. Battery University- it is a slow, gradual rate of decay- as usually it can happen in minutes or even hours. if you wish to disagree as to slow and gradual degradation for defective Li Ion batteries, you are welcome to contact the engineers posting at Battery University. Warn you, they have PhDs publishing in this field.

Thank you for the second level agreement- namely that an iOS install, and the stress it causes, will expose battery flaws. Why do you mention disagreeing when I mentioned the very same?

So your battery was weak and likely flawed, and did not survive the iOS transition, or its decay coincided with the iOS, you and 100,k other users in November? Versus 500+ millions out there which transited successfully.

Fact remains you have a defective battery. And another assessment- a new one will have no issues. Where will your iOS argument fall then? iOS does in some batteries but not the replacement?
