iOS 10.1 Battery drain

"It seems like that all battery detection is screw up." You are likely bang on, there is a built-in control module in the battery whom reports parameters. Your usual troubleshooting, Reset, Apple Support up to Genius Bar (maybe they can reset a firmware) may help. But all bets are off if your battery has over 500-600 cycles. With age, the lithium ion path inside looks like a dried up rock canyon and Li Ions can not longer more easily back and forth, from once a highway, it is a rapid river kayaking. Whatever Apple Support or an authorized center may recommend it is likely the best and only step, and I do believe your issue resolvable.

I beg to differ!? 1st genius bar visit: diagnostics show good battery, told it's a Software issue + did restore with no backup from iCloud or computer. 2nd genius bar visit: diagnostics show good battery, told it's not a Software issue and I had to REPLACE THE PHONE. Refused to change the battery. Mumbled something about a hardware issue, motherboard... based on nothing. Autorized service provider refuses to replace battery also. How is any of this helpful?

"Mumbled something about a hardware issue, motherboard... based on nothing. Autorized service provider refuses to replace battery also. How is any of this helpful?" I do not know, you tell us. Was the issue resolved? Not easy to guess what were your specific diagnostic findings. Others went through the same steps, had the battery replaced, at store or authorized center, and issue resolved. A recommendation for phone replacement is the rarest of troubleshooting advice anyone posted here. Several users had their newer phones replaced as a store courtesy or via Apple Care, but none of them mentioned anything about the logic-board. Did it also fail the test? was the battery found swollen or leaking? no idea so cannot speculate to what was found inside your phone to prompt a full replacement. How can one use your experience as a benchmark for those with 700+ cycled batteries whom a simple swap resolved it..

March last year got a brand new macbook pro, and it kept freezing and crashing. With iPhone videos documenting it, Genius Bar also found kernel panic, so gave me another one. Same thing. School work frozen, all lost, a few times a day. The Genius Bar tech believed it software - and it is very long to try one by one programs when you have to be up and running. Could it be Adobe flash.. microsoft? cloud? maddening- not installing them yet still freezing or shutting down. Hours and hours or reinstall, clean, apps again.. On the other hand, Sr Apple Advisor tracking my case was adamant that he knew it to be hardware, not software. Since there were forums out there discussing the issue, they all pointed to the OS, and one would have to draw a lotto ticket to get two defective macs in a row. With the second machine freezing, I finally accepted the Sr Apple support's recommendation; he sent another machine from another batch to my Apple Store, where the same tech skeptically handed it over anticipating no resolution. 10 months later, I have not had a single crash and the case was closed. I will never know what inside caused such issues on a new machine, but have no regrets having followed the replacement advice. If your new phone works, hopefully that resolves it for you.

"Was the issue resolved? Not easy to guess what were your specific diagnostic findings. .. Did it also fail the test? was the battery found swollen or leaking? no idea so cannot speculate to what was found inside your phone to prompt a full replacement." The diagnostics revealed NOTHING. All the genius could point to was the steady decline in battery charge level over time, saying "something" was behind the steady 15% drop/hour. They commented that the phone was in excellent shape but refused to open it to see if battery was swollen or leaking eventhough phone was warm. Nothing they showed or told me warranted a replacement.

I have 700 cycles, was ready pay for a new battery and that proved impossible with Apple or approved service providers.

If it makes you feel better, I had an iPhone 5 that was overheating - started happening regularly after I accidentally left it overnight facedown with the flashlight on. The Genius Bar took my phone and promptly replaced it, telling me they take no chances with warm phones, in case it is also a short. Battery replacement was not an option, it was a specific type of symptom/action trigger they have. Lost the 49$ Zagg shield with it but the next iPhone 5 I had survived 2+ years, including cold and the Iraqi desert.

"yes, it falls under the faulty battery serial numbers," I can't believe a brand new phone (not even 1.5 years old) would work fine and then randomly start shutting down because of a "faulty battery" when NOTHING ever happened before 10.2" Gabrioska, 1.5 years old means nothing in the tech world, could be 547 days and cycles, or could be 800 cycles. We do know what Apple recall states about your battery- it is expected to die prematurely, with erratic beahviour and shutdown. We also know that when you play with low power mode, you let the phone adjust the amperage. (e.g. you are toying with battery demand). When a battery is new, works well, think of a caribbean blue lagoon, or beautiful Nevada highway stretching miles. Electrons move at light speed, cruise control, and Li Ions move back and forth, fast, as the highway or calm water allow. Now, if you read the Apple Battery performance FAQ's, degradation is normal. When batteries age, especially with your recall terms, highway becomes a rocky bumpy kind or rapid river cayaking. The gel changes properties. Ions no longer move fast nor normally, hitting bumps. And when these things happen, the controller expects light speed but gets intermittent power. As ions clog or bump inside the liquid, you can also get minisurges etc. Sure, a new iOS, new parameters, new calibration, amperage, maybe new safeties who knows the correlation. I prefer more built-in safety shutting down my phone than overheating and burning down my car. In your case you are fortunate to be covered by a recall, and when the time comes, you will get a working battery.

I also got an iphone 6, which of it's not eligible for the battery change, and I'm experiencing the same problem. Maybe it is a problematic interaction between some batteries and the update, as some of my friends are not experiencing the same problem.My phone is almost 2 years old, but it worked pretty well until iOs 10. The first version of it made the battery level drop faster, but it still worked, with the latest updates the problem became worse, the phone dies at any percentage of battery, even when fulled charged. Then, I have to put it to charge so I'm able to turn it on again, and when I do it, the battery percentage is the same as it was before it shut down. There's no way that's a individual problem. I tried everything Apple told me to, none of them worked, my cellphone is now as useful as a rock if I don't have a charger.

***IMPORTANT***

Today after sending 6 times my iPhone 6 64Gb (i bought it 14 months ago) to Apple repair center throw Vodafone (carrier where i bought it), they finally replaced the battery with new one. I will test the phone and report here.

Happy end after persist 6 times 🙂

I know that, the problem is, I live in Brazil an apple's support in here is pretty expensive, as the phone, the possible damage in my battery was not caused by me, it's life is not even close to the end. My phone is no longer in warranty and they will probably charge me for a battery replacement that I wasn't supposed do pay for. Apple needs to make a recall of those iPhone 6 batteries, it is not possible that all of the people having this problem were reckless and damaged their phone. All I want iis an official answer to may problem and I solution without me having to pay for.

SIMAOCBR, can you give more detail about how you've managed this? You mean to say you sent it to Vodafone by post 6 times? Or you dropped it in person at your local Vodafone shop, also 6 times? And then Vodafone sent it onwards to Apple, and it came back 5 times unrepaired, and finally the 6th time they replaced the battery despite the phone being out of warranty (since you said it's 14 months old)? The previous 5 times you just re-sent it back (or re-dropped it back at the Vodafone shop) right away, or you waited a while? And the 6th time they just did it, to get rid of you? So you were phone-less for a few weeks whilst all this happened? Just trying to understand the procedure you undertook.

Yet here I am looking at my iPhone 3 and 3 GS with great functioning batteries. Both that have spent many summers here in the high desert with temps above 100 f. So many people having the same problem. How much do you get paid from Apple belisarius?

I'm pretty aware of the weather issues, but the phone only complete 550 cycles, I guess it was supposed to last 1500, but I'm no sure. Even with the hot weather, I don't think it was supposed to have any problems, specially because the phone worked pretty well until the updates. In any case, I will look for help in a authorized center, eventhough I still think is too much of a coincidence and that Apple should take a stand. I only hope that the possible repair is not too costly.

If the phones aren't supposed to work in higher temperatures such as the ones in Brazil and other places, they were not supposed to be selled here, right? The problem is obviously is not the weather, thank you for the acid answer, I mean it haha
