iOS 10.1 Battery drain

Have any of you provided Apple feedback at http://www.apple.com/feedback/? It is the actual way to contact Apple. I did ref iOS 10.

If not, you can repeat post here but it does not constitute feedback.

"Same problem here - iPhone 6 dies with 36% battery as soon as it gets slightly chilled in temperatures well above freezing, anything below about 8C."

JTTM, I am curious; first, have you submitted feedback to Apple? http://www.apple.com/feedback/iphone.html

And what happened last winter, have you frequently used, charged or discharged your phone below 10C?

"Also how do you explain the erratic and what seems to be inaccurate battery gauge?" I fully agree with you that a new iOS is no reason to go running to buy a new battery. Fortunately, based on what we know so far, the majority, vast majority of those whom upgraded have no issues.

Reference battery gauge, you already conceded that a lot of it is battery-relative, built on. You can direct that question to Apple, and I already posted the Apple feedback link. Very important, that is the main venue for actual iPhone feedback, not the forum. http://www.apple.com/feedback/iphone.html

As you heard, Apple is moving towards its own Battery Division. They may be best to answer as to why they created one, why the new diagnostic tools, whether or not health indicators actually work. The answers Battery University provides, updated as recently as weeks ago, give you the industrial standard and reality. What works, what does not, etc. Why health tests are not accurate as to a battery being defective or not.

I did not design Pokemon Go, but, if I were users, I would give poor app feedback and write to Apple complaining about it.

There is a reason why I avoid smartphone drain, it just bricks the batteries pretty fast. But I do not hold any iOS responsible, as I am well aware that just apps can do it in a days. Base iOS have the least amount of drain possible. Add PG and you went 600x % base iOS mAh demand...

"maybe going back to an older software version?" You cannot go to a prior iOS library image..

"Or the battery is now screwed forever?" Unknown if yours is. However, any Li-Ion health goes down, never up. They are expected to last 300-500 cycles. Demand/drain relative, this can be 300 or even less. Just electrical engineering fact. Again, no idea where yours is- diagnostics might give you a clue. And if it goes bad, the good news, it goes bad very fat (it is an exponential curve, with 60-30% vertical plunge degradation in weeks). Again, no idea if it is your case.

If it's a software issue, why not come up with an update or something like it? - http://www.apple.com/feedback/iphone.html

Do you think it could be, instead, an actual problem that needs battery replacement? One way only to check. Let's say your health reads below 90%, and dropping, weekly one battery swap will give you answers (as it did for 6-8 people that changed battery or iPhones and problem is gone). if it does not work, you can be reimbursed. If it does work, then your answer is there. However, if your battery stays steady over 90% for weeks, as it should, then no need to rush it and wait for an update, be it very inconvenient to drag a charger everywhere.

Again, i know no one with shutting down 10.2 or high drain, not even the girl's 800+ cycles iphone 5.

Keep looking, there are many complaints and many threads on 10.2 issues. Mine is a 10.2 issue in fact and shutting Siri off has helped. Siri used 85% of my battery over 24 hours on standby when I wasn't even using Siri. I was losing 10% per hour, and my battery is fine now that i turned Siri off.

New Battery Update 1:

Got a new Battery this afternoon.

Only took and hour.

Charged it to 99%

My daughter used it for 40 minutes and it used just 3%.

She has been using her phone for another 40 minutes and the battery is down to 93%

Greeting Paikinator, how is the replacement battery holding up?

I have a iphone 6 purchased oct 2015. I rang apple initially December 5th, diagnostic on battery was fine so told to wait a month for software update. Waited then rang again the other day diagnostic wouldn't send for some reason so they wanted the phone back. They sent me a box so I sent it back and I just received this on email : -

Your product arrived at our repair center, but our technicians weren't able to process your repair request. We’re sending the product to you along with a letter that provides more information. If you have questions about the letter, feel free to Contact Apple Support to review your options. Be sure to use the same Repair ID. We apologize for any inconvenience.

Hey, it is unfortunate you are experiencing this. Your battery appears to be defective. Correction- it is defective. Whatever caused the issue is, to some of us, not as important as helping you resolve it. Ref battery, there are several ways you can go about it, including any authorized battery service center in your city.

Apple takes its feedback at http://www.apple.com/feedback/iphone.html

The other twelve that replaced their battery have resolved it. Also, there are rumors that this forum is also read by tech industry journalists checking facts. If your replacing the battery and it works, that is another tidbit that matters. I do not know what Apple is doing about it, but it is a sure bet that the tops at Cuppertino will have to answer questions these fast approaching days.

"I'm to the point that I'm ready to see if buying a new battery will help but I am wondering if I should go ahead and upgrade to 10.2 before I get a new battery installed or whether to leave it at 10.1.1. Any suggestions?"

I did an upgrade to 10.1.1 and it hosed everything. Then I tried to go to a Beta that didn't change my underlying battery issue.

I did a recovery Mode Factory reset that updated me to 10.2 by that time. Then I had the battery replaced.

I would say that updating to 10.2 will have no ill effects except on the existing battery. You may find that 10.2 accelerates the bad battery behavior of rapid drain and spontaneous shutdown. However a new battery will work just fine with 10.2

I would upgrade to 10.2 and then swap the Battery.

You won't be sorry.

Hey genya, I would never brush your question aside, but I cannot answer it. 😕 Your question enters the broader interpretation of the phenomena, apple revenue strategy; users going in that direction or writing as you had posts deleted, with Community Forum reminders and warnings of account suspension. Apple Support Communities Use Agreement lists the forum acceptable topics. If you can track news separately, or provide Apple feedback via their feedback page is the best and only direction I can provide. At the moment there is no room of maneuver to answer philosophically or industrially. Maybe later that will make sense.

Hope you can understand that tangible, practical solution tips is the best that those whom resolved it can offer here. Some people were fortunate to have Apple support replace their battery, or even iPhone. Or authorized repair centers etc. What I do find amazing, however, is that total strangers can come here, discuss it and resolve successfully the issue for so many.

Genya, you sound very smart and able to read between the lines. I am not arguing with you, just explain that my hands are ties. Do you ever use your apple id.. facetime, imessage etc.. it only works if not blocked. If posting against the forum guidelines, that can happen. Also they can contact your employer, it says at Apple Support Communities Use Agreement. Above, you will notice a lot of responses to people whose posts appear nowhere as the original must have been removed.

"replace their prevoiusly flawlessly working batteries." Maybe the previous yr plus. Not only we do not know them being flawless during the shutdown period, but if the replacement resolves it, means the previous were not at all flawless. I also know that some people play Pokemon Go and do 700 cycles in 12 months. Sorry, but those batteries are done, would you not agree? It states it in apple's battery FAQ. Quite a few of those whom replaced successfully admitted that their prev batteries had gone well over the official shelf life. Discussing how the sequence happened for those failing to fully fail may not be deemed acceptable by those reading the forum more and more carefully.

Genya, I am jealous- living in a colder climate with nothing so romantic looking like the Danube during a summertime evening.

Can provide you some pointers. First if you get a chance, check out the youtube video "Life Cycle of a Lithium battery pack, how many cycles should it last?" And basic Li Ion short videos. Then the Apple battery website may give you additional ideas how the potency has gone up for laptops, from 300 to 1000 cycles, and operating parameters:

By now, you know that it all boils down to how those Electrons travel through the circuit, and Lithium Ions go back to the positive cathode. A car analogy would be the fuel line and fuel pump. If a car's engine just shuts down, it is far more likely that the causes could be fuel line leak, dry tank or fuel pump long before the ECU computer having a code error. You have to trust honest feedback experience that I did try in the past 3d party batteries numerous times. Am allergic to them as, dubious quality or source, they could last from a few weeks to just a few cycles. Wasted time and money, often unable to return them as, when defective, they are classified as dangerous goods. The Li liquid inside, if not produced under stringent QC, is never going to work predictably. A few hours of ambient air overexposure can fail them during assembly - is happened even to the 6S recall. And any shutdown like you re experiencing suggest that, in the lower Depth of Discharge (sub 30%), your particular battery cannot deliver those electrons. Fuel is cut off. You are also welcome to go read 3d party reviews on Amazon, some are really bad, 30-50% failure in weeks. As the video explains, the module controller is another key part- and Apple's modules tend to be very good and meant to work and calibrate with Apple's own firmware. Once you introduce non-OEM of questionable quality, no technician on the planet can guarantee a long term working battery. And the fact that your got 2 years of the previous one, amazing but not the norm.

So am not trying to convince you to spend money, just that, technically speaking, I would never have expected your non-OEM battery to work more than a dozen to a few hundred cycles. And, as all those here whom replaced them resolved it, am quite confident that where you to do so, it will work for you. I still recommend an Apple Authorized Serivce center, via https://locate.apple.com/hu/en/service/?pt=3&lat=47.5&***=19.0833333&address=Bud apest&carrier=T-Mobile

If this does not work, welcome to come back and call me names. But am very confident it will work and, in your case, it is not iOS related even if it appears so.

've had my iPhone 6 for well over two years with no issues [...] I've had three iPhones - a 3G, 4, and this 6 - over the last 9 years with barely a problem The good news for you is that your issue is resolvable- fully, and no it is not the iOS. At x1 daily cycles, you went through 730 cycles / 24 months. Amazing. At x 1.5 that is 1000 cycles- superlative. yet you did that to a 500 cycle/80% battery http://www.apple.com/ca/batteries/service-and-recycling/. Which means, if you check all the prev posts, you were well over its operational life. Just electrical science, if you wish arguing that, Battery University is your start. Your Li Ion ferrite liquid had nothing left to give and was any cycle away from going bad. And yes, when they fail, they have the exact symptoms.

Withing the dozen whom all successfully replaced battery, all those that had high shelf life came back later to admit expecting too much.

The 3/4/5 examples are poor- just the screen drew as much as half less amperage! The whole phone had 50 times less uses than today (esp the 3). Usage also matters. My Gf has 800 cycles on her 5 as she barely lets it drop below 30% (the key Li Ion live or die figure). Had I used my battery 100-10% full through in the iraqi desert like some friends did, they did not get fifty days out of it... Again, battery university will give you a good idea as to the industrial lifespan.

I understand the user above with 400-500 cycle issues, but not you.

So the good news is that it is fixable, unlikely to be the iOS, and once you replace the old battery with a new one, issue is gone.
