iOS 10.1 Battery drain

Read reports in 5 different languages (read write 3 only). There are lots threads- I agree. 500 million users. I cannot take the few threads and a few dozen users posting here and generalize to 500+ million users. I also know that the issue is real - no disagreement there- but not even close to universal. Any why since the holidays meeting and asking iPhones users, they are unaware that it even exists. Ringed my gf's and mom's older iPhones through tests- nothing. No drain. Paikinator's iPhone 5 at lesser health failed immediately with 10. My Gf's 800+ cycle iPhone 5 has an awesome health figure. So this means is that the issue is not universal and no coding is heating or draining these iPhones I tested.So can you explain this? Also emailed to a few industry gurus whose articles no doubt you read (their emails are often on their web pages). They also admitted that the issue is real but not universal. Some of their colleagues have it, some not at all.

Years ago, a science class within a science degree, had to create a logicboard for a lab exam in teams of 2. Drew the circuit diagrams; then we selected the parts/processor, resistors capacitors etc. We created the code math separately, and triple verified it. Then we drew the circuit on the copper plate. Drilled the holes. Dipped it in acid for 24 hours. After removing and seeing the circuit, inspected it and we began soldering after each component after individual testing. Finally, we programmed the multiplexer etc, and the code. Once done, had to connect it to a screen and have it display as a first test. The growling commenced in some teams that had issues. Was it a component or the code? One team had a code error as it transcribed it erroneously from the paper to the multiplexer- just a 0 or a 1. Others had to do the oscilloscope and ampermetre test part by part on their board and found the culprit. The point of this arc is that if you replace a hardware component and the issue is gone, then coding error is not the cause.

So if there is some error, as I said before, it relates to hardware safety parameters released through an OS. Reason being is that shutdowns are 99.99% in the tech world safety breaker shuts. Another possibility would be a short. I hope you can see why the universal drain theory poses some challenges if it is not universal. Then you have awesome users like Adrian whom admit playing Pokemon Go for hours a day and putting his battery to the "sword"prior to it failing, as he wrote. PG is a battery killer hog. No surprise his battery failed with iOS 10, and the replacement works despite huge testing demand.

Hope yours gets fixed soon.

"The fact that Apple seem to be acknowledging there might be an issue with IOS 10.2 is promising, but i wont hold my breath that the next update fixes it. Nothing is that easy." I agree Adrian. Also, you are right, some apps are terrible. For example Pokemon Go. Another example, GPS. Yesterday my gf drove as we navigated an watched (she listened) to President elect Trumps's speech. The iPhone 6S warmed up a bit, nothing major, and drained steadily, faster but within speck. Another process I avoid at all costs is the iCloud photo sync. Especially when leaving your home, any iCloud stuff alternates from wifi to digital antenna. Huge hogs. But I noticed high drains on these even on my former iPhone with iOS 8 and 9 as well. So some apps, as you wrote are just very bad and drain batteries enough, I dare say, to push them outside healthy parameters.

Also, please consider that these batteries loose life very fast if drained rapidly below 30-40%. The Li Ion electrolyte reaction eats the plates and cathode fast below those numbers.

The reason I agree on your pragmatism relative to the iOS is because people unaware that they have some hardware component out of spec are still going to get poor performance no matter the iOS. Yes, shutdowns can be unprogrammed/removed with coding, app usage (mAh) can also be kept within certain figures, but a battery's overall ability to perform, charge discharge or drain are chemical processes that are factory and environmentally related. Once a battery begins draining abnormally, it is like plasma ghosting, there to only get worse.

Your having a steady performer makes me happy for you.

I never have stated I believe it is a universal issue. I believe it takes a rare combinations of apps, settings, and app requests that very few run into that starts the corruption cycle. Either that or bad code in the update / setup side and app errors take place from there. No 2 phones are exactly alike (when you consider exact hardware and software and settings), keep that in mind. Also, there are people replacing batteries that have had the drain issue come back.

Ack. Though no replacement failures yet posted here. Contact Adrian (ljoscure.. something). He is purposely abusing his iPhone to test his new battery. Two weeks of gaming and he may have dropped 0.4% health. A few of the 10 users went for 3d party battery kits, and they know that, at 20$ and questionable reviews, they may fail very early but the issue is gone. However, take any iPhone and play WoW, OG, Real Racing 3 and a few others, they will fail rapidly, unfortunately.

In the case of plsvn user, above, his symptoms started with iOS 10. But there was no corruption. Catch: his 'healthy' tested battery was on the faulty battery recall list, which specifically warned of poor performance, shorter life and shutdowns (Apple announcement). The Li Ion plates cathodes and electrolytes were stored at ambient air (Apple announcement) which means the oxidate faster under use. Plsvn's battery replacement works. 10.2. tools were released to collect on these batteries.

Not trying to minimalise or normalize the issue, by far. The truth is am extremely disappointed in Li Ion reliability and technology and following these trends for years now. Every iOS release bring about such issues (former iPhone 5 shutdowns and drain started the day I installed iOS7. Battery replacement fixed it). Also find it unacceptable for people to pay 800$ to 1200 British pounds for an item with components rated for months of use, not years. Going about with a charger. I am counting the days until industrial reliability shoots up. Take the chips for example, they can run a decade 24/7. Gorilla screen- hard to break. Antennas etc, years. Show me a battery and I feel lucky if it even runs after a hot day outside.

Hello, I am still here.

🙂

The testing of the new battery is going well.

No shutdowns and I am charging overnight, taking phone off to work about 8am and then draining it till at about 9pm by which point it is usually at less than 1% and shuts itself down. I am purposefully letting it shut down, usually with Pokemon Go running.

Rinse and repeat.

[As an aside, I finally caught a Dragonite so on the 1st release of Pokemon, I am only missing the regional variations of Kangashkan, Mr. Mime and Farfetch'd. Ironically, although I live in Europe, I have not caught Mr. Mime yet. I visited Canada last August and in 3 weeks I caught 3 Tauros which is the U.S. and Canada's regional Pokemon.]

Anyway, back to the original post, this is a waiting game as if my theory is correct and it is IOS 10 then it could be months before the battery gives in like the last one.

However, I am a patient man, or it could indeed all be fixed by the new battery.

Coconut Battery is reporting wear between 7% and 5%, as we know the only people who can gauge the accurate wear is Apple themselves.

I plan to take it into my local Apple reseller for diagnostics on the 22nd of this month and every month so Apple has a record of the degradation process on IOS 10.

For the purposes of this test I am exclusively using an official Apple charger, as they tried to blame 3rd party ones at the beginning of all this and I did use (reputable) 3rd parties for about a quarter of my charges on the old, faulty battery.

See you laters Alligators.

Adrian.

"No shutdowns and I am charging overnight, taking phone off to work about 8am and then draining it till at about 9pm by which point it is usually at less than 1% and shuts itself down. I am purposefully letting it shut down, usually with Pokemon Go running." Good heavens dear Adrian what are you trying to prove? If my operators were half as determined as you I would never have an information gap. Had a surgery earlier so am nauseated badly, but your reply made me chuckle.

Congrats on your Dragonite capture!

Years ago when the iPhone 5 came out I got it and played these two games 100- near shutdown for weeks (Galaxy on Fire and Real Racing 2/3). The battery was heating in my hands playing. When iOS7 rolled out it just started draining, heating and shutting down. Apple found it dying at the 6 month mark and replaced it under Apple Care. I learned my lessons and the 300 hrs I played since have been on iPad only. The iPad has a larger battery, different architecture, better cooling surface area. Have not dented the iPad a bit and i also watched TV news.

Are you sure going about this objectively? If you send this battery to an early grave, all you would have done is proven that high drain, heat an demand kills any battery regardless of iOS. We already know that. But it does not prove that, under normal operating conditions and cycling (which PG is not), this iOS in particular kills it. Same for Android.

That aside, if I had your PG passion as I have for other things (luckily on a PC or iPad) I would not care about the battery and just replace it when its time came.

"For the purposes of this test I am exclusively using an official Apple charger, as they tried to blame 3rd party ones at the beginning of all this and I did use (reputable) 3rd parties for about a quarter of my charges on the old, faulty battery." I also heard that pigs can fly under certain conditions. This is a new low and am not impressed with whomever went after your charger instead of the iOS, apps and battery. We are not talking the former Chinese cheap electro-shocking cables here... Not impressed. And they even sell 3d party docks and chargers in stores!!!

Update for my 6 plus. Replaced the battery 3 days ago. This seems to have fixed my problem. I have good battery life again. Still I had zero battery issues before the upgrade to 10.1.1. So yes the battery fixed my problem. But the OS update caused the issues. I guess the old OS was much better written and more efficient.

Congrats, 11/11. And am happy if it works, even happier if it last (I think you ordered that named 3d party battery, it gets great reviews). Question for you, is this battery holds out without problems, what would you make then of the iOS 10s code? Each iOS is different that the others, a different power print. A good battery will handle up or down amperage variety no matter the install. The 10 appears to be on the high side. Yet, GF's 5 has 800 cycles, 10.2, no issues. It should have failed just by age, but it has not despite the upgrade. I will use your brand if she needs a sudden replacement.

An old, poor, worn-out or just defective battery, on the marginal edge of failure, has a burnt-in drain memory, a fragile Li Ion electrolyte balance as the electrons move from the anode to cathode and back. Think a hard rock, narrow river bed, with no overflow capacity. As soon as you alter the parameters with iOS 10, more drain, it began showing its failure. Have read about this happening for many years and various iOS versions, Android as well, and very unfortunate the 10 has seemingly done the same for some users. The battery you have now hopefully will last, it will print itself to iOS 10, and I have no idea how iOS 11 might affect it.

Buongiorno Luigi, la batteria sembra essere il problema. Abbiamo avuto undici su undici utenti quali risolto i loro problema, sostituendo la loro batteria. Se dico di più, essi saranno cancellare il post. Tuttavia, sembra che ci sia un lotto difettoso di batterie là fuori che non poteva gestire iOS 10 domanda amperaggio. Apple ora si rifiuta di sostituire le batterie 'fine'. Ma altri centri ufficiali certificati li sostituiranno. Se funziona, si prega di restituire e fateci sapere.

Turning off Siri had no noticeable effect on battery life/drain for me on 10.2. I'm going to try to get battery changed out this weekend.

FYI - There's a lot of folks tweeting about battery drain and/or shutdown and iOS 10 on twitter (including me). Unless it is just the same group of folks from here tweeting there...I gotta think it is more than a isolated number.

Also one of the reporters who wrote the article on battery issues previously is working on a follow up and I pointed him here if he wasn't already monitoring. Additionally, I provided him screenshots of the issue as well as details of my case.

So our Battery update has held strong.

We are seeing somewhat normal drain at this point with zero rapid drain or spontaneous shutdown any longer.

We did a clean install on the phone and it upgraded us to a nice Factory Restore of 10.2.

No complaints from my daughter any more.

My iPhone 6 running 10.2 suffering from exactly this. Took it in to Apple Store in November, all fine according to their tests. Today powered it off with 43% charge, tried to turn it back on and got dead phone message, left it for an hour, turned it on again to a 51% charge. ***?????

I am having the exact same issue ever since I upgraded the software to 10.0. I have since upgrade to 10.2, but I'm still having the same issue. My battery will be at 75% and then die in a matter of seconds. I plug the phone in and it jumps back up to 75%. I've spoken with apple support, and they are telling me that the battery is damaged. I have to pay to repair it. I am not paying to have my battery replaced when I didn't damage the phone. There are many people complaining of the same issue, so I doubt damage to the phone is the cause. Having a phone that can die at any moment is not very useful. Was anyone able to resolve the issue?

"Also one of the reporters who wrote the article on battery issues previously is working on a follow up and I pointed him here if he wasn't already monitoring. Additionally, I provided him screenshots of the issue as well as details of my case." Do you mean Mr Roberts?
