iOS 10.1 Battery drain

Not sure if this helps in any way whatsoever, but my old iPhone 6S Plus started having serious battery drain issues then one day actually died. Under warranty from the phone company I have the contract with I was given a *brand new* iPhone 6S Plus. Set it up as a totally new phone under a new apple ID, didn't put ANY apps on it. (Stupidly) updated it to 10.2. So we're talking about a phone literally as close as it can be to how Apple have provided it. See the screenshot below... over 50% battery charge lost from simply NOT using the phone for 8 hours. Not sure where the 12 minute usage came from as if I'd have used any apps they'd show right there on the screen.

So although various phones may be suffering from various different bugs, I can confirm that whatever is affecting MY phone is NOT anything to do with any apps. It's not a 'corrupted' app because I didn't run any. This is an iPhone as 'virgin' as it can get, utterly untouched, yet getting through as much battery in an hour on standby as it should be getting through in a day.

Since then I've tried the various 'suggestions' - resetting the settings. Erase and reset fully. DFU. I'm sad to report that NOTHING has solved the battery drain. Obviously I've gone back to my phone provider and informed them I have a broken phone which sadly will need to be replaced under warranty. Again.

i don't want to argue with you either, but facts are still facts. Wanted to give a try to a reinstall, did it yesterday, spent like 3 hours (itunes said "no restore is possible, so had to dfu it), lost all my login essentials, have to search for every one of them (gmail, waze, bank app., paypal, etc), and utnil not found, and entered again, i am stuck with all my daily important things. Of course, the battery problem persisted, today immediate shutdown happened again, at 20%, and no chances to charge it from PC USB, only from 230V, so if i have only a USB cable on me, i am totally f....d. Even my previous, old battery lasted until the end, eg. 1%, at least i could calculate it, how much juice i have left until shutdown, and even got a notice at 20%, and 10%. Now? Nothing on earth. Probably there should be a new option in one of the following updates: getting a notice at, let's say 50%? Then at 30%. And then it can shutdown itself at 20%. It is not an option to have a 230V plug by myself every day. By now, after 2 hours i managed to turn it back on. Here is my battery test too. To be honest, i dont even care anymore if my account will be suspended (what for exactly? Facts?), i never used any apple apps, no facetime, no videos, i'm not doing pokemon either, i am not a spender on AppStore. I would use a pre-ios10 jailbreak as good as having this issues. I never liked iphones anyway, don't even know, why i'm having one... my prejudices proved themselves... i am deeply disappointed... and this is not a speculation, just my facts, my personal experience, and my personal (mostly objective though) opinion... i am a sad, sad panda now

There is more to using these as mere imprinting, there is frequency, liquid/gel resistance, there is an entire science. I also used 'operational' not shelf-life. Shelf life for a discharged Li Ion battery is a year max and dead after. 50% capacity in storage with regular trickle charging. welcome to read Dr Pete'r Novak's research. Operational is something altogether. For example, <100 cycles which cross the 30-0 threshold can do a battery. It may reach 600, but in bad shape. Then you take the gf, she is getting 20 hrs a day, 800 cycles as she just happens to plug her often around 50%. Or a dozen cycles in heat - and at 122F/50C those who had their phones- regardless of make- open in the desert got two weeks out of them.

And when you mention theory, it means the way things work. For many people- and do not shy of recalling what they wrote, their working assumption was that it was the iOS. After replacement, such as paikinator, he recanted with the battery being the issue after all. He and other returned a few times to report no more issues. Clinical trials need success with half a dozen people you had twice that here no fails.

if you accept that any major upgrade rearranges some parameters, you are still discussing an impact on battery.

There are also one user whom reported bad Siri drain- not the rest. Online read of a few whom had a coding error, Genius Bar redid their firmware (they can do it in the lab), bug is gone. But let's talk over 600 cycles, and the coding is the last thing a technician is supposed to look at.

"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?"

iPhone 3GS iOS 6 and poor battery life. If you google it, you will find over 350,000 entries on 3GS battery issues. Does not mean the phone was not a success, 3Gs, a phone that shipped up to 20 million according to Statista, versus 250 million 6 in one year alone. Less demand, less amperage, smaller screen. Funny, and if you include the number of my posts I had deleted, two for recommending your solution no less-might think twice about assuming being paid by Apple. Also have a Sep 2003 LG Clamshell that travels the world with me as secondary alarm in case the iPhone is silent or low volume. Including the combat tour, managing its temperature. Still works the clammie- 13 years on. Since my Gf gets terrific life out of her 5 with iOS 10.2, if I am a betting person, you are a cell user with percentile anxiety, likely to plug it often if going down and rarely let it slip below 30 or 0 with hard usage. Usage relative, maybe you kept the 3Gs as a home iPod, no SiM card/ cell tower ping, in which case life bets are off as it stays in a controlled environment and very low drain. Like my clammie. But, not, I do not believe a second that you used that phone, as a phone, 2,550+ days, >3000 cycles. Nice joke but mastering forensics is a professional trait, and personal attacks on me do not help users resolve their issue.

toothsaw, if anyone here is able to prove, definitely as you wrote, something wrong with code, he would have applied and been hired with a high six figure income. First thing, battery level measure you are mentioned, is built on the battery control module.

Second, you are introducing new variables, hopefully that is all of them. Wrote experiencing poor battery life <540/67% with iOS 9; replacing it, no issues for a while, then new issues. So we know you had a battery life issue prior to iOS 10. And that you use a battery pack, which, even though sold in an Apple store (like my poor Belkin kit years ago), may have an impact on your batter- or any battery- you connect to it, simply as these phones were designed to work with normal AC/DC conversion via the Apple Charger. That battery pack was at some point used on an iPhone 5 as well, which makes for two gens and three batteries used with it.

The attached pic is from the UL report- ran a series of basic electrical safety anything short of this, there is no way to tell if, after so many years and cycles, your battery pack still supplies proper DC power. All these packs have a finite, relatively short life and cycles, and may even be well below Apple's own battery lie expectancy. They are not endorsed by any manufacturer even though widely available in stores. Either case, quite the variable in this situation. I think Apple Support, diagnostics might help, and avoiding that charger maybe the best thing for this or any other future phone.

If i had a magic wand id wave it and fix remotely all these issues. Hope your appointment goes smoothly and issue are fixed. sharing a screenshot of mine. In your case Facebook may be normal to burn a high percentage as it is a complex message fusion center.

"and who was talking about Samsung?" YOU ARE. i will not reply with face palms, as I do not condone violence towards women. when you say Android, you say this chart- Samsung. The #1 dog is also the majority parts suppliers, and shares manufacturing sources with the rest. So its particular issues also are an entire market problem. Keep this in mind next time when recommending users resolve this minor, resolvable iPhone issue by going to Android.

so, what you all think? After switching off at 26% again, i overcharged it again, after reaching 100% i left in on the charge for another 1-2 hour(s). Took it off the charger yesterday 12PM, today 9AM still at 100%, while i listened to music and browsed some facebook on safari. Is this a normal behavior frommy battery-failured, logicboard-broken phone? Anyone else with such symptoms?

Belisarius, please, do you NOT answer, i'm not fancy reading your incompetent guessings, nor hypocritical or lectural sayings. We can chat about Hungary, Budapest, anything else.

"You are good, I dropped it twice days before Do you think the battery shook or bent a bit" Aha, you did not do physics! Some say 2000 G, on tiles from 4 feet. A good site here, I took the pic

http://physics.stackexchange.com/questions/173244/the-g-force-of-common-objects- hitting-the-floor With 3D rotation, a case, I can see it being hundreds or just 50Gs. even inside a case, it will bend and regain shape, naked eye cannot see that. Now imagine that was the battery corner, the battery bends. I would feel lucky if it worked a few more months after.

This is why no one reinserts the same battery, once technicians peel it out, they bend like chocolate as you wrote, it can never be trusted again. I think Apple always puts in a new one- was told that once. Apple and all makers tell you how they test drops. But of course a 5 or SE will not bend like a 6/ Plus , and accidental drops are drops. Maybe in your case the drop accelerated its age effect, we cannot generalize that every single issue here is caused by user dropping his phone on tiles. But every single drop, even on carpet, does beat up a circuit, see the pic, and why a case helps immeasurably. A trick I learned is to kick it. If it falls, ** kicking it I give the phone a horizontal vector so then it glides safely on a floor.

Case, umm, i do not think they will let me post recommendations, but any High G load military rated case, they come in lots of colors and varying degrees of cuteness.

Sam, every installation repings, retests and recertifies your iPhones' specs. Add to it firmware. The actual installation stresses it, demands tons of power, follows with indexing, sportlight etc. My 6 month old iphone 5 battery failed me when installing iOS 7. Two days later, new battery, issue gone. At the time I also went on macworld forums, the same issues had happened to some, few owners with 4, 4S, or Android out there. A new OS install, whether 9.3.5 or 10 or 11, will repeat the process. And then, all these iOSes have the same core architecture. The 6S recall issues started summertime with iOS... 9; iOS 10 was announced as having new battery tools. Any OS parameters to protect electronics are programmable, but it takes a circuit problem to trigger the shorts. Similarly, you can unprogram shutdowns, but then the owner may just complain of rapid drain below 40%. Still out of spec, and quite dangerous.

In this other pic, also taken Nov 2016, had just read on 10 issues, note erratic App measurement readings from 92% health, to 99%. iOS 9.3.5. If the Apps are correct, like the first pic i posted, Aug 2016 iPhone 6S should have a failing battery Sep to Nov 2017, below 75%. It will not pass the iOS 11 install. Would be easy to speculate or correlate iOS 11 with drain, but not the case. I have Apple Care until 2018 so they will replace it. Point is, with iOS 9.3.5, my 6S was headed for a similar premature battery demise, 12-14 months range, same as yours, before upgrading to 10.2. It is below expectations. Recently provided Apple feedback recommending they spend 8 billion $ (factory, R&D, tech acquisition) to make their own Apple batteries and start a smart-power revolution. And not have batteries with missing guts like ATL with Samsung, and they supply Apple as well.

Sorry friend, I was able to recoup from cloud my iOS 9.3.5 screenshots I took last month. According to them my battery will fail 11-14 month after purchase, Sep to Nov 2017, below 500 cycles. If there was another iOS released those months, easy to correlate issues, but not related. Pics taken with iOS 9. 10 is not making it any worse, same rate of decline. Apple Care would cover it for me. If you have a chance to google recent days news, and how people are repairing them this should not surprise you.

Yesterday Unexpected shut down at 40%.

I charge all night and monitor battery percentage.

Look how fast it drop and the drastiscal drop at the end(25-15%, 15-10%, 10-5% & 5-2%)

Also check the battery percentage drastic rising during charging (10-42%)

From 100-80&, facebook browsing.

From 80-0%, no app running background. Only status app running with screen on and flashlight on.

At 75% i press on clearmemory then it drop of about 20% usage.

I also attach memory info screen.

I also attach a battery log of yesterday when it shutdown around 40% .

I was talking about my 6+.

My 4 dont have battery issue. After 5 year and 726 Cycle it have 87% battery healt.

Cant't say more about my 6+ than suddenly fail simce 10.0.2

First pic is my iPhone 4.

Secomd pic is my iPhone 6+.

""Paid bots". Very possible. Nobody has that much time unless it's thier job." You are correct, I am paid. I am paid a high income- full income- to stay home, supposedly am sufficiently smart to have a paid degree by my employer, to study plus recoup from a surgery (hence crutches in the picture); Side by side with academic software and research, I also get emails the fabrications you come up with.

Speaking of fabrications, the odds of my working for Apple are quite less than yours working for some Android competitor seeking to undermine consumer confidence in Apple, or intoxicate people with speculation or bad idea- such as your 3d party 20$ battery which may, hope not, fry your phone one day. At this point, the forum has so much visibility that if you keep doing what you are doing, violating the terms of use, etc, they will just suspend you.

" I was talking about my 6+. My 4 dont have battery issue. After 5 year and 726 Cycle it have 87% battery healt. Cant't say more about my 6+ than suddenly fail simce 10.0.2" Alain, demande a n'importe qui a Politechnique, Centre Reparation Apple Montreal, Pointe-Claire, Trois-Rivieres, Quebec ou Chicoutimi- meme reponse. Comparing a 5 with a 6 is not a good example. We just replaced the Gf's iPhone 5 battery. Genius Bar found it with OVER 1200 cycles. 68% health. No drain or issues with it- just inconsistent GUI response. Then take my 6S- it will fail this Sep-October, one year old, and I might get shutdowns too. It works greatly, just declining, and this started with iOS 9.3.5,d ay 1. A long cry from my 4 or iP5, 2 years no issues until trading in for this 6S. I provided Apple feedback, and Apple Care will cover my faulty battery when it fails in a few months.

The Genius Bar tech reaffirmed the obvious, that they have shutdown as long as he has worked at the store, and are rare- but why they carry spare batteries. Lots of them. Also it is not an iOS thing; even if an iOS rolls new parameters, it takes a decaying or out of spec hardware to trigger the shutdowns. There may be correlation, not causation. This is why I know no one with the issue- even the Gf's coworker whom i helped, I never met. But search online, you will find shutdown forums going all the way to the iP4 in 2011. he also gave me pics of the replaced battery, it had swollen on one side, but my GF's experience is abnormal, 3 years 1200 cycles, not the norm. I can only wish my next battery will do the same on 6S.

Also, you got no one here with iPhone SE, not is there an iPad issue. Different built. Anyways, follow support center. The good news, unlike November and conflicting user experience, store staffs are now consistent with their resolution steps.

her iPhone is super zippy now, like a new iP5, iOS 10.2.1.
