iOS 10.1 Battery drain

Mxmrjoe, thanks very much. So basically your phone was still in warranty, which is what I wanted to establish. Many phones that have this problem are no longer in warranty, so I held some hope (very little hope, indeed) that yours might have been out of warranty yet Apple would have nevertheless agreed to the swap. Since your phone was in warranty it would have been absolutely outrageous if Apple had not acted in the way they did. So well done, but I think your experience was entirely normal and satisfactory.

The real litmus test is to see whether Apple will ever acknowledge a problem and offer redress to phones that are out of warranty and would normally not qualify for any kind of free service. This is also the reason why I'm carrying a huge battery case on my phone instead of paying £69 to Apple for a new battery (which I refuse to do out of principle -- the Mophie battery case cost far more!); or far cheaper for a non-OEM battery (which I don't want to do in order not to kill my eligibility for a potential free battery replacement, if one ever comes). Come autumn, we'll see if I'll ever be an Apple customer again. I'm meanwhile researching OnePluses and Pixels -- but still holding with Apple for a few months. All very sad; all very unsatisfactory.

(PS: to any users on this forum who reply to every single post with the exact same harassing repetitive message, again and again and again, good news -- it's Sunday, day off, so a reply to this message is neither necessary nor welcome! You know who you are. Thanks! :) )

Thankfully it is Saturday on several other continents, reality does not revolve around any specific one. Am surprised that your posts promoting non Apple services is still here- not too mention brands. Fortunately, there are probable well trained HA advisors at your work place that could clarify the definition. unsure if you are a Pixel spokesperson, and why you did not mention as well their ongoing issues- and when they reached more than six figure phones, they might have a forum page somewhere, "battery drain issues on Pixel and we'll get back to you as soon as we have more information."

If you wish to promote other brands, it really is the wrong forum.

Ok, some say 10.1, you say 10.1.1, at some point there may be a 10.1.1.5. With all due respect to your battery care, and to my own knowledge and efforts, myself will never pretend being able to take or nor care perfectly- unlike leather, car paint, or elite cycling gear. In this case the components have their own life, manufacturer, and miriad other things no person can control. Some users claimed iOS 5, 6 7, battery issues, iOS 9 (seen the forums?) iOS 10. Lost batteries to one bad app in 3 months (iPhone 5 2013). If you want to break it down granularly, all yo are doing is breaking down your own argument. Your hardware replaced, successfully, under warranty, now running as well as hundreds of millions of iPhones with 10 and no issues. Your answer does not apply to users without warranty, nor is your speculation helpful. If fifteen users replaced hardware, of which twelve swapped batteries, three swapped phones as you did, and issue is gone, guess what, pretty self explanatory. No other lab test could exonerate code speculation such as these numbers. Another fellow had a phone replacement with issues, once Apple Support assists him, his last fix, without doubt, will resolve it.

Hi guys. I'm joining the club of iPhone users with random shutdowns with battery in the 5%-50% range.

As many users here, it usually happens around 30-40% battery, but sometimes my iPhone 6 shut off at 45-50%

One trick I've learned is to plug it in a battery pack for about 1 minute; the phone turns on and resets the charge level and then it works until the battery is really empty. A few times it shut off again between 20-25%, but it happened only a couple of times in 2 months.

I thought it was related to using iOS 10.2.1 beta, but reverting to 10.2 had no effect on this issue and as I read here and in many other forums, the issue also hits iOS 10.1.

Apple is surely listening, but even if they have no clue on what's causing this, I hope they understand that ignoring this very annoying bug and all the users reporting it it's not healthy for the company :/

You're really funny if you think people are going to spend £20 on a official cable that will break 3 months after use. I would rather purchase a MFI Certified Cable off from amazon with positive reviews for £10. The same with a wall adapter.

What is funny is your answer, and other forum members here will not agree with you but myself, and the real world. First, have never had an Apple Cable break or fail on its own- not even when carried across the world in a hot dessert. Once, a Miele vacuum cleaner chewed such a cable, but that was the vacuum cleaner head, not the cable.

2- myself like so many users, with so many apple gadgets etc, I am nearly swamped by Apple cables. each successive iPhone I got came with more. And More adapters, AND MORE OEM and cable adapters And GF came with hers.

3- When a few people died from using fake cables, Apple replaced, free of charge, the fakes up to 6 feet (store tested them by easily pulling them apart), under its fake cable replacement program. So MORE genuine Apple cable, 0 cost.

Conclusion? if you have to buy Apple cables for 20pounds and they last you three months, you MUST have a dog. Or a Miele Vacuum cleaner. Or loose yours each time you go out...

lnyxzee, how about a bit of fairness. Let's take 488 reviews; as you know, for those 500 million iPhones out there, right now, there are billions of OEM cables, some with each new iPhone generations, others with iPads. My most worn out cable is the one in my car, 5 years old, I squish it each ride closing my armrest, phone nearby me. No fraying, and survived hot summers and very cold winters. Also, Apple replaces them free if defective, sometimes well beyond the 1 year. Have lost a single cable years ago by mixing it with a non-Apple charger, it likely hated that charger's amperage. Apple's rubber is far more flexible and resilient and is an integral part to amperage control http://www.righto.com/2012/05/apple-iphone-charger-teardown-quality.html?m=1 Anyways, will not go into a lengthy discussion on how fake poor 0.99$ cables are far more notorious to kill iPhones and people; consider that billions plus figure knowing that no such incidents were recorded with working genuine OEM. Bought once a cheaper Belkin, blew three fuses in my car and fried an iphone 4's circuit. Never again.

http://bgr.com/2016/12/02/apple-charger-price-fake-counterfeit/ "The independent UL laboratory ran a series of basic electrical safety tests on fake chargers bought online from stores around the world. The results weren’t good: of the 400 counterfeit Apple chargers purchased, 397 failed a basic safety test conducted by the UL laboratory:

“In total, we tested 400 adapters and the results were literally shocking. The overall failure rate exceeded 99 percent. All but three failed our basic safety tests and were fire and shock hazards. Twelve were so poorly designed and constructed that they posed a risk of lethal electrocution to the user. “"

Next to the Food and Drug Administration, and your UK/EU industrial and health standards, UL is the world top Guru that certifies anything electric, all to power bars that will save any computer, electronic from surges. If they say they are outrageously bad, is there a reason to doubt them? And yes, fake chargers contribute to earlier battery death as well, that is the first piece of hardware that takes the abuse.

Sorry, this phone is a complete mess, having issues with touchscreen too, now and then.

As I was saying, my battery is less than 1 year old, had to change it because after 540 recharge cycles, its health dropped to 67% and I was having shutdown issues even with iOS 9.

After changing it, issues were gone. They got back after updating to iOS 10.2.

My cable is MFi certified, so is my battery pack (bought in an Apple Store) and it outputs 1.0 A.

Have been using that battery pack since iPhone 5 and never had this sudden-shutdown issue, so it's definitely something in the software which is causing a wrong battery level measure which triggers the shutdown.

Far from implying that what you said is wrong (it surely isn't), I'd like to point out that:

1. I've also been using the very same battery pack to back-up charge my iPad 3rd gen, iPad Pro 12.9 and other electronic, battery-powered, mobile devices with no battery damaging or deterioration.

I don't use it as the main power source to recharge my devices, I just use it in emergency situations and, as I said, when I'm out and my phone shuts down at 40-45% for just a minute, in order to have it back and start properly discharging the phone in order to preserve battery life. I usually never plug the phone to its charger if above 20% and never unplug it until above 80-90%

2. every battery-operated device that supporta recharging, iPhone included, is designed to be recharged by a DC power source. The ripple in AC/DC converters' output voltage is an issue the charging circuitry has to take into account to avoid stressing the battery. Using a purely continuous power source for recharging, as a battery pack, is far better than an AC/DC converter, even so because, as you said, the charging control circuitry is built-in to the battery itself.

The Apple's original wall charger is just designed and engineered so that the output ripple is as small as possible and the current output is controlled to avoid surges that surely can damage the battery. By using a battery pack with a current-limited output, you can obtain a better charge, because the ripple is absent and the current output is still limited.

My iPhone 6 original battery must have been damaged because I used to charge it when driving using a car adapter which was MFi certified, but I suspect that the power socket in my car is defective; in fact, the car charger broke after a few months of usage. I bought another and it broke too after some other time. That is what probably killed my first battery. When I changed the battery last March and stopped charging the phone with a car adapter, but used the battery pack instead, everything worked fine for 8 months.

Update. I took my iPhone 6 to the Los Angeles Womens March. It went from 100% to shutdown in maybe 90 minutes. I was texting and doing a bit of calling, no Pokemon Go this time. I was pretty angry given that I was in a crowd of thousands of people, couldn't move, and trying to find my friends. Fortunately I knew to bring a spare battery this time so I was OK once I managed to fish it out while pressed up against the crowds. The safety implications of this problem are unnerving.

Today I went to my local Apple Store (I'd previously done a chat with them and they said my battery diagnostics came out "OK"). The Genius ran more diagnostics and said my battery is working at 94%, so they will NOT replace it, even if I pay. They said they thought it was a software corruption issue (implying it's third party software) and I said yes, software, yours. They said the only thing they would recommend is for me to replace the phone, resisting the urge to tell me about all the iPhone 7s they had in stock. I told them that if Apple doesn't fix this issue soon, my next phone will NOT be an Apple. (I've already replaced my Macbook Pro with a Dell, so I'm halfway out of their ecosystem anyway.)

Disappointing but not surprising.

Also, I'm not looking for any more reactions from the poster whose handle starts with b. I've read enough of how it couldn't possibly be Apple's fault. Thanks for your concern.

"Also, I'm not looking for any more reactions from the poster whose handle starts with b. I've read enough of how it couldn't possibly be Apple's fault." Have seen no B user discuss faults- as you do, for example, but tangible, technical advice and resolution. If fifteen people here resolved their issue, most without warranty, your following or not is your choice- no one else's. A couple more will soon be returning here to post success. Again, what you do with that information is your only exclusive doing.

Oh, by the way, saying that my case adds up some more variables, to me is just another confirmation there's an iOS 10/10.1/10.2 issue in battery management. I have the very same issue other users have even with a different starting situation.

I reported my issues to the company that changed my battery 10 months ago and they said they know there's an issue with iOS 10.2 battery measure. They could have taken my money and changed my battery once again; why tellingg me to wait for a software update instead of charging me for an unnecessary service? They make a living out of these services, they told me something against their own business if it wasn't true.

"My iPhone 6 original battery must have been damaged because I used to charge it when driving using a car adapter which was MFi certified, but I suspect that the power socket in my car is defective; in fact, the car charger broke after a few months of usage. I bought another and it broke too after some other time. That is what probably killed my first battery." Toothaw you are hilarious. Anything else not mentioning, like do you go swimming with them phones? j/k! Again, more variables you are bringing us. Don't you find it funny that before your last post, I mentioned car charger, cable, fuses and damaged iPhone 4. Am not telepathic, but this is how these things go sometime.... Anyway, you just come out of the blue now to mention car charging (DC current BTW) as killing your first iPhone 6 battery (had that with an iPhone 4), strokes away after I just wrote the same. Then a few sentences away, you defend another DC power source... My answer is still the same, unless testing your DC charger to an ampermeter, how do I know if the pack battery still delivering clean, steady 1 Amp DC power?.. I do not know- only inside a lab with an amperemeter and oscilloscope can one be sure of that. But like any battery based DC charger, it has now aged with wear and tear after so many years. And if the charger's battery is now out of speck, all your batteries are doing is getting out of spec amperage. Perhaps even intermittent. So between car charging, battery pack, and other factors, unsure what else about your specific recurrence.

As for your car charger, it could easily break if the devices you plug in have a different amperage demand than that supplied by your car battery. And the charger is low grade. And with all Made in China plug-ins (see UL link above) they all have poor QC and 99% do not match the specs written on them and fail electrical testing.

Ok, no idea which company, do not think it Apple Support. To my knowledge Apple Support for iPhones has not halted hardware troubleshooting pending some software release. Speculating on that company's motives is an unscientific guess. Anyway, you have many users here whom fixed it and returned to claim, as one wrote "Amazing" iOS 10.2 life now. So much for your company's argument.

And adding that you had a similar issue with another iOS, you are just proving that such issues do occur, at times, irrespective of iOS. In your case anyway.
