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

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.

I am now questioning the quality of the batteries being used in iPhones so I have been doing some digging.


As far as I can gather, suppliers of batteries to Apple have been:


  • ATL
  • Dynapack
  • Simplo
  • Desai
  • Sunwonda


Interestingly, Samsung look like they have switched to ATL after the Note 7 fiasco, those batteries were made by Samsung's own SDI division.


I am struggling to find the manufacturer of Google Pixel's batteries, but it would appear they too are having issues with sudden shutdowns and drain, so I am guessing it is the same manufacturer as the iPhone.


Read into the above what you will, a few years ago I read a book which won the 2009 Economist Book Of The Year Award.


I loved it.


It was called, "Poorly Made In China"

I think a recap is needed.


To summarise:


  1. Almost all of us here experienced this issue more severely after upgrading to IOS 10;
  2. The batteries of the iPhones appear to be poor quality and are degrading faster than a premium phone battery should;
  3. In most cases a battery replacement resolved the issue, so far I am the only one trying to break my replacement battery to prove point 2, please feel free to join me;
  4. Apple have only admitted and offered replacements for, quoting Apple, "A very small number" of iPhone 6s batteries manufactured during certain months due to a fault in the manufacturing process;
  5. We are all pretty angry as we expect more from Apple, particularly in view of the price we pay for the product and the loyalty we have to the brand.

Just for me... really. Thanks for thinking of me.


Anyhow.

The more you discharge below 30%, the faster the discharge, the more STRESS - you will see the word STRESS in hundreds of phrases, written by the PhD gurus.

Great and useful info, but not what you were talking about.

You were talking about with the stress of IT professionals in installing firmware.

Also doesn't really go with how you were talking about Firmware/OS installs stressing out the hardware.


But what you posted above is at least pertinent info and useful for people in aggregate.


However it is also not really pertinent to an OS install causing a glitch where the battery indicator shows rapid drain and the phone shuts off suddenly when the batteries are mostly reading as ok.

It is more directly relevant to show that a Factory reset puts a phone back at its functional state with a fully functioning battery once the malicious code has been eradicated.


Any rapid charge or discharge causes stress. Every cell dropping fast below 30% looses its reactive capacity to charge exponentially faster. So that battery heads for an early life. As some cells begin dying, so does the erratic behaviour.

Certainly that would be true if the battery indicator was actually working correctly and measuring the battery charges and discharges correctly, but I am not convinced there is any actual rapid discharge.


As can be seen from numerous postings, the iOS 10.1.1 upgrade seemed to initiate glitchy behavior that lead to poor readings by the battery meter. The readings were off, perhaps not reading the battery correctly at all.


My experience of more than a month of constant "rapid discharges" by a teenager before letting dad know the phone wasn't working correctly would have likely led to a defunct battery. And yet the battery in the iPhone 5 is fully functional.


Once I eradicated the bad OS install, the battery is fully functioning with largely the same durability as there was before the glitch.


So defunct Battery? Not in my case.

Messed up battery indicator and malfunctioning OS install much more likely.


Happy new year to you and all of your family.

Keep posting useful information.

For 8 weeks now my iPhone has had to rely on a portable power bank while away from home. It has plenty of charge on the battery. It would be nice to be able to trust that my iPhone will even work -especially with a family member in hospital--so I can be reached. Right now it is unreliable. And I, like so many others, am extraordinarily frustrated.

While we appreciate the great lengths to which you battery pushers and statistics folks have gone to inform us that we just really ought to expect that we are the % for whom the devices will fail, that we need to lie down and quietly go away, I want you to know it IS okay for you to refrain from posting your "helpful" hints.

Here's why we're here.

1. Our iPhone suddenly does not work as it should. (And yes. Since iOS 10.1.1)

2. We paid a good deal of money for it.

3. WE didn't break it.

4. We can't fix it.

5. We expect Apple to fix it.

We would really like Apple to acknowledge that thousands of iPhones owners through no fault of our own are now owners of a dud of a device.Like myself, there were undoubtedly massive numbers of customers patiently awaiting an update-- only to be disappointed as there was NO FIX for us in iOS 10.2. We would appreciate knowing that they ARE working on the fix right now. That one will be provided to us as quickly as possible. (tossing a new battery our way is not the solution)

Quite frankly, the silence from Apple is making me angrier than anything else. It's galling to see ads for shiny new iPhones while I've got an expensive iPhone in my pocket that won't even work properly so pardon me if

I'm feeling a bit duped.

I would like to know that Apple believes that their customers matter. My question: Has anyone actually SEEN an Apple acknowledgement? Any hope at all or promise of a solution?? If you have seen a real answer from Apple please direct me and others here where to find it. (Other than their statement that "a small number of devices were affected" which is nonsense and all posting here know that. We need something more recent)

It was implied once in this Forum that any negative feedback toward Apple would be censored. I'm going to trust that they still have some integrity. I just want my ----ing phone to work. Two months is far too long. This should not be something we have to beg for.

Dear remgumby


It is obviously very unfortunate having a family member in hospital during the holidays, and NYE. Really so. I trust you did let Apple know this through their Apple care, and especially, a Senior Adviser. They have quite a few discretionary powers.


I also trust that you tried resets. Some, like Paikinator, have had success - or partial the least. If none of these worked for you, we will for sure refrain to post statistics if you do understand that:


- Buying any technology is like winning a lottery, except the ticket is that of an eventual dud

- Any items warranted for a year, pass that year mark, is fair game. They are engineered to work for a year with very few failures.

- A "dud" device, as you called it, can rarely, if ever be repaired by OTA releases.

- You are an infinitesimal problem in a sea of hundreds of millions of working phones.


1- Your iPhone is expected to die.

2 - It does cost a great deal of money, and hence the 8% Apple Care and x2 extra years cost is a very serious must. Did you get it and, if not, why?

3 - The very act of using them, breaks them. Eventually..

4 - You cannot fix them, but Apple, Genius bar, authorized places e.g. Best Buy, surely can if it is the battery

5 - Apple has no reason to fix it, particularly if outside warranty and due to normal wear and tear. Wrong expectation, does not match reality. You sign on that dot when clicking "I Agree". The fact that many users in their second year, outside warranty, do get a significant assistance/swap/discount from Apple is testimony to their # 1 CS rating. We can name tons of companies which never do.


All you have to do when outside, seeing people with iphones' just ask them, "Hey Is your working?"There is nearly 10/10 odds they are running iOS 10 not shutting down, and they never heard of a problem.


"We would really like Apple to acknowledge that thousands of iPhones owners through no fault of our own are now owners of a dud of a device." That is why Apple replaces up to tens of thousands iPhones a week under warranty. And why they replaced Mjolcures iPhone in Manhattan even though his iPhone was 2 year old..


"We would appreciate knowing that they ARE working on the fix right now." To the exact same length as the fix for iOS 4, 7 and 8 issues. Most of those owners, on those forums, had their phone batteries, or phones, replaced. No iOS fix repairs a "dud" device as you call it. And no, there was no iOS fix for those past years and iOSes with hardware problems.


"tossing a new battery our way is not the solution" Why not? It is for those who returned to claim success.


"the silence from Apple is making me angrier than anything else" What did Apple Sr Support advise you to do? They take calls and are generally quite understanding.


Has anyone actually SEEN an Apple acknowledgement? Any hope at all or promise of a solution?? There were several software related acknowledgements, iPhones freezing. There is also a battery replacement program for specific iPhones 6/6S, identifiable by batch and Ser #. Hundreds of millions of iPhones, yes, they know which batch matches which Ser #. Should your iPhone eventually become subject to such a recall, even if you had to pay previously, Apple would subsequently reimburse or credit your cost. Goes with recalls anywhere in NA.


"A small number of devices were affected, which is nonsense." How many? I see dozens of members posting. Even if thousands, it is still small. Even if tens of thousands still small, normal and just reality.

"It was implied once in this Forum that any negative feedback toward Apple would be censored." About 2 out of every 5 replies that I receive are quite inventive and speculative; when attempting to answer, they are gone, deleted. Very few here ever see them (I see them because the are in my mailbox emailed before being deleted in the Forum). Apple does not censor feedback, but it does delete unscientific jibrish which misleads customers away from actual troubleshooting. Censoring implies suppression of information. Speculation and wild speculation (e.g. "most iPhones are affected" etc) do not qualify as information, facts and not even as an opinion. They are pure invention.


Again, it is unfortunate that you are tied with hospital care for loved ones, but this has no bearing on the technical reality of your problem. You can reset your phone, try base-OS runs, have the battery replaced for free, or have it replaced risk-free, or have the phone replaced. These are controllable variables, within your power.


The sooner you understand that healthy devices never just shut off, with iOS 10, 10.1 and even 10.2, you will understand that the troubleshooting steps are within your hands and in your court- like other users did here- and not some iOS developper.

Jan 1, 2017 6:07 AM in response to losdelrock

Adrian, does it matter how or what killed your battery? Could it be Pokemon Go? An intensive App reported to drain very fast iPads, iPhones long before iOS 10 was released. How do you know whether or not PG was not optimized for iOS 10 and lead to faster drain which did kill your battery? If so, would the App be the culprit and not the iOS?


So how come iOS 10 is not killing your battery ATM? For some it was 10, others 10.1, and 10.2. 7.4, 8.1 People are running out of idea to explain why the end effect- which is what truly matters- is a dead battery.

Jan 1, 2017 6:20 AM in response to _Belisarius___

These are questions I would expect Apple to answer.


Their silence is rude and shows a complete lack of respect for the many loyal customers on this thread.


One of the reasons I jumped ship from Android was because I was experiencing battery drain from all sorts of apps.


I believed the Apple vetting process for apps was more meticulous, including battery drain, than the Play store.


Looks like I was wrong.


Since my issues with IOS 10 I have paid for and installed a battery wear indicator and stat app.


After a week it is showing me 1% wear level so the math would indicate that my new battery will last much less than 2 years.


It would have been great to have had a like for like on a 6s on IOS 9 to compare and put it beyond doubt.


I will feedback over the next few months how the wear progresses.

Update 8:


Well I charged and left the iPhone 5 in standby.

I checked the Battery Meter status every few hours and the battery drain seemed smooth.

The phone Drained from 100% down to 26% over 26 hours which is normal for this old phone with an old battery.

I plugged it in at this point taking into account Belisarius' information on trying to not let the phone discharge below 30%.


Next I will fully get the phone active on my account and see how it performs in the real world with some regular use.

Happy New Year Paikinator, to your and all your family members.


"As can be seen from numerous postings, the iOS 10.1.1 upgrade seemed to initiate glitchy behavior that lead to poor readings by the battery meter. The readings were off, perhaps not reading the battery correctly at all." We both agree on the sequence, although perhaps not the causality. My argument is that old or tired or near-death batteries fail the iOS 10 upgrade, or the MC can no longer provide steady info during the reset processes imposed by the new install. Best analogy, have you ever troubleshot a glitchy SDD/HDD that still seems to run, but doing a new install after the reformat it no longer works? Culprit could be one stuck sector. It also takes a single erratic part of the battery cell to throw it off. Once the battery electronics report an error, by default, Apple devices log and keep the "Fail" ping. On macs, once the Service Battery sign appears, it will reappear and become permanent quite rapidly.


As your iPhone 5 batteries are old, it means nothing in their behavior will surprise you. Unlike the 6/6S/7, many new power hungry apps are not available on iPhone 5. Personally, if there was an opt out option, I would keep a 4 5 or 5S at the last working iOS level. Because of iOS 10 ergonomics, which I dislike, I reversed to 9 and been refusing 10 since. The GF updated her iPhone 5 just before the final rollback date; could not reverse to 9. After a week of poor battery life with 10 (although no sudden power-offs), she took my advice and Facebook; is back to better daily charge than she last had with iOS 9.


If you do go back to own profile/image, do not be surprised if it returns to weird behavior. Apps place a higher load on the battery, and its behavior could be different than your controlled environment test and -1%/hr.


Factory Reset usually cleans up glitchy legacy issues, including lag, app freeze and so on. Some people do not know how to do one- including the girl- the entire life of the phone.

Jan 1, 2017 2:25 PM in response to _Belisarius___

Hi Belisarius, always good to have open dialogue, I just wish Apple would open up and talk!


🙂


I am pretty sure we all agree and understand that a battery is a consumable and will fail depending on how it is used, I have no problem with that.


My problem is that all these issues happened instantly after IOS 10 and not just to me as can be seen on this thread.


I installed the Battery wear app in desperation after my phone started shutting down on the old battery.


I have had awful experiences with these types of apps on Android when I was trying to identify battery drain on my: HTC/Galaxy S/SII/Note 4.


I gave up on the Note 4 and went to the iPhone 6s and all through IOS 9 I was so pleased with my decision.


This battery app I am using seems pretty decent, but I am not trying to gain 100% accurate metrics, just roughly see what state my battery is in and how fast it is degrading


My old battery was less than a year old when it started failing, it got replaced under the "Lucky Lotto" scheme (as I call it) whereby my 6s was entitled to a free replacement as the serial number fell in the lucky range.


The phone was not wiped and I have noticed no shutdowns, so in my case the faulty battery was causing the shutdowns.


So by that logic, the others on this thread who are having the shutdown issue should have a new battery fitted.


Apple should pay for this as I honestly believe IOS 10 has cycled these batteries over their usable limit.


My battery drain still persists, it is not as great as on the failed battery, but it is still there.


So, we shall have to wait and see how long this new battery lasts.


If indeed it is 2 years (or thereabouts) with me just having hatched a few of these new baby Pokemon that Niantic have just released, I will be delighted.


If it is less than a year, then I will not be delighted, simple.


I have a horrible feeling Christmas will help Apple in it's damage limitation act as a lot of people, who assumed their batteries or phones were too old and past it, will have asked Santa for new ones.


So I guess we will never know how many batteries IOS 10 has ruined.


As mentioned in a previous post many pages ago, Apple, instead of living up to it's "Break away from Big Brother Microsoft" advert all those years ago has turned into the very thing it was asking it's potential audience to avoid.


How ironic.


Adrian.

Jan 1, 2017 2:56 PM in response to Mjolcresure

So, let's sum up. iOS10 creates a problem for many of us, we create a thread here hoping for a solution, Apple completely ignores the hundreds and hundreds of us, then apparently gets tired of bad publicity and hires someone to join this thread ( ~Belisarius~ ) to simply argue anything said, turning this thread into a useless exchange and thus drive people away.


Really Apple? Wow. I am utterly disgusted.

I sent a one-line message on here a few days ago reminding contributors of the well-known principle that fedding the trolls isn't advisable. That's all I said, wholly unspecifically, and I didn't refer to anyone or anything in particular, neither by name nor otherwise. The message was of course deleted by the censors (as no doubt this one will be) under the pretext of lack of civility. But at least it will have reached those who subscribe to the topic by email - those messages make it to all subscribers before the censors do their work! Please, keep to the topic and don't feed the trolls.
