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

No, not at all, and disappointing from a smart guy as yourself. This is called a Straman Fallacy- twisting words and beating up a trumped up statement. I wrote "have been built since the very first analog mobile phone." Not with iOS 10. And I also will link below some of hundreds of links, some shutdowns (including June iP6), predating iOS 10. So, they existed in nature before iOS 10, right? https://www.youtube.com/watch?v=Klme6nE8sqs Contrary to your claim that "99% of users had this with iOS 10" that is a false statement.Google Pixel, growing forums 3 months in, shutdowns. 3 million hits for Android. If you wish to learn the difference between fact theory or law, check it online. Circuit protection are not a theory, they are LAW. A Law is something beyond a theory, a known, tried and tested way things work. In some parts of the world, legally mandated by agencies such as the US Department of Energy.


iPhone 5 with iOS 7 randomly shuts off and

iPhone 6s shuts down with over 40% battery power

https://discussions.apple.com/thread/5451794?tstart=0

iPhone5 shuts down at 20%-30% battery since new IOS7 was installed


As far as I am concerned, you would have gotten similar symptoms if you randomly decided to factory reset iOS 8, 9 or 10. An example of theory is if a phone shuts down one in 20 cycles, and after hypothesis, we conclude that that Radiology worker was accidentally bringing their phone in the MRI chamber- likely causing magnetic inductance and triggering a shutdown. But normal wear and tear shutdowns are Law.


If you ever drop your iPhone in the bath (knock wood), and it shuts off, thank engineers whom built in the circuit breaker to prevent 7 milliamps from hurting you.

You could top charge to 100% then let is slowly drain to 0% (or shutdown) + 2 hours. Then full charge to 100% + 2 hrs. On a good battery avoid doing this frequently, Li Ion hates that. Then check numbers. A backup and a General/Settings/Reset/ Factory is another way of resetting everything, then reinstalling your backup. As for the Genius Bar, they sometimes take walk-ins but are much more appreciative if you book online. Click iPhone/Hardware or Performance/Make a Reservation. You should get several blocks, same day or ensuing days. They will thoroughly test your phone for 30 min or so. Apple Phone support also can book the appointment for you but I prefer online http://www.apple.com/ca/retail/geniusbar/.

Yes, finally, after over a year we have closure:


https://www.apple.com/iphone-battery-and-performance/


But, it has left a bad taste in the mouth and a hole in many people's pockets who have upgraded at a substantial cost when there was no need to.


Honesty and clarity, thats all we want Apple, and in a shorter timescale please.


My iPhone 6s battery, which was one of the faulty batch and was replaced under warranty just over a year ago, is now showing as bad. A year for a premium phone battery is simply not long enough.


I will be changing the battery on it when, as announced, they reduce the cost of the battery replacement.


My 6s works perfectly well and does not need upgrading.

Update to the issue which has gone for my phone (6, 64 GB, 16 months old, load-average twice a week):

Herein, I only refer to the problem of sudden shutdown event (SSE) with incorrect battery status display and power-on-event at the same level with charger attached (i.e. shutdown at 25% and power-up with charger at 25%). The value of 25% is just a random number, so I had another SSE at 40%, and a third one at 18%.

Steps done so far:

  • After SSE: phone charged in powered-off state (attached charger, slide to power-off).
  • Hard-reset done (power- and home button pressed until apple logo is displayed - about 10 seconds). I've done the first hard-reset already before charging.
  • It was important that in the powered-on state the phone reached 100% battery counter status. Herein, the indication for it was the following:
    After charging and having 100% in the battery status, used to wait at least for a minute, then checked the iPhone Settings -> Battery-> scrolled down and checked if the usage counter correctly started (it displays hours that passed after last complete charging for usage, and standby). If it still didn't count, the battery-controller (or whatever you call it) didn't reach the correct 100% state.
    Note: if you charge the phone in powered-off state -> I've observed that it is required to power it on and wait in order to get the 100%: but if you power on, do not detach the charger from the iPhone. Detach it after the power-on and full 100% displayed in the status.
  • Apps: Of course, I checked some of my apps/settings: the most important setting - in my eyes - was to remove ALL apps running or at least being displayed in the background. The second important step - was to modify iCloud email account from PUSH to PULL-requests (Settings -> Mail -> Accounts -> iCloud). Further, I observed that even if the location sharing was set to "off", there were some apps which had an undefined state for the share-option (so no setting was set as default: in this case I just defined it).
  • I monitored the battery status with Battery Life for at least 3 battery usage cycles (3 times charged).
  • My personal guess is: the installer for the iOS 10 update messed up the battery controller status.
    For such an OTA (over-the-air) update, the customer expectation is that it runs smoothly. In this case, the things went totally wrong.
  • I still didn't check if any intermediate charging (i.e. at 40% to 100%) will again mess up the controller status: herein - from time to time I need to do it - if I go for a longer journey. I will post update to it.

Maybe, some steps were redundant, but let's see. For the moment, it works fine.

Hi there. It's been a long time since my last post but I've been following this thread though.

  • iPhone 6S Plus here, with sudden death issues at 17-40% since iOS 10.1.1
  • Done everything: restore with icloud, restore as a new phone, Apple Support diagnostics via Twitter (i'm from Portugal, no such thing as Apple Genius here), battery calibration
  • Updated to iOS 10.2.1: my experience so far is pretty good. The sudden death issue has stopped and the battery life seems extended. I've done two full cycles from 100% to 5% battery with a normal use of 10 to 12h (facebook, music, podcasts, safari, low graphics gaming and some minecraft).


I guess the issue, if not completely solved, is at least contained for some users.

And as I always stated, the issue (for my case) was bound to software issues. Nothing to do with hardware.

If the issue returns I'll be back here.


Hope it helps

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.

Jan 1, 2017 1:16 AM in response to Mjolcresure

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.

Jan 1, 2017 4:23 AM in response to remgumby

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.
