iOS 10.1 Battery drain

With all these posts, it is obvious that the problem is not random - all issues seem to have occurred since the last two updates. Everyone has a similar story to tell, and it's great ppl get a chance to vent. I think it would be more helpful if Apple would reach out and provide a solution. As suggested in one msg, I downloaded an app called "battery life". It says my battery is BAD - 44.8% battery wear level. Did the updates exacerbate the demise of the battery? Were the batteries defective to begin with? My phone is 2 yrs old and as far as they are concerned, it is "tough luck, Charlie"!! This is poor customer service, and very bad public relations. We all paid a LOT of money for the phones and they should make it right. So instead of posting yet another similar experience, lets figure out how to get Apple to act and make us whole again. Do we start contacting TV stations & newspapers? They all usually have a reporter that helps consumers. What about individual states consumer protection offices? Strength in numbers, people.

I'm aware of what this post is about. I'm one of the original posters and the first to tip this to Gordon with Forbes to make it public. This is about a bug in iOS 10.1.1 and up (10.2 is worse) that disconnects the communication between the OS and battery controller. This is why phones are shutting off in the first place. This bug has grown beyond the 30% mark and like me, thousands of iPhones are shutting off at any percentage only related to battery draw. For example, at 92% I can watch an entire movie and be left with just over 30%. But, at 92% if I use Maps or Camera or any other high draw app the phone shuts off within minutes because the OS thinks the battery is dead. Plug it in and seconds later its back to 92%. My point is random shut offs, high drain and other reported problems are all related to this bug. As a developer we have stopped production on all software until this is resolved. I've heard that iOS 10.2.1 beta is showing progress in the right direction. I haven't had the time to test this yet but will soon. It may be released to the public this Tuesday or next.

My iPhone 6 is doing the exact same thing. It started shortly after the iOS upgrade. It appears through the information I could find on the internet that Apple believes this issue only affects a select group of iPhone 6S's but as others have indicated on this blog, including myself, it is not.

The popularity of this thread might be an interesting matter of discussion. I don't feel better in getting any record acknowledgement. In any case this is a clear indication that this issue is having a widespread impact on customers.

What I am really concerned about is the complete lack of any official statement about this.

It's been denial mode for more than 2 months.

Happy Christmas from my HTC

How can i make a test on my battery by Applecare ?

I have been having this issue since 10.1.1, but it wasn't just at 30%. Most of the time it'd be at 60% or so, and once, it was even at 92% (after 10 minutes of being on and fully charged to 100%.) I think the issue is the iOS is actually harming the battery, because when I originally took my phone in to test the battery, it was at 86% capacity. Apple told me to wipe my phone and restart from a backup, which I did, but didn't help at all. I went in two weeks later and my phone's battery was suddenly showing that it was at 76% capacity. 10% battery capacity in 2 weeks? Not normal. Anyways, I bit the bullet and just paid the $80 for a new battery as it was causing me both inconvenience and also left me feeling unsafe, having a battery that would die at any given moment. I repaired the battery yesterday and haven't had a ton of time to mess with it, but last night, I charged it to about 50% and had it on for about 7 hours, using Snapchat and Instagram a ton (apps that usually killed my phone within minutes of opening the app) and the phone drained normally, down to 6%. I'm not sure that Apple will ever acknowledge the issue, but if you're fed up like I was, I recommend getting the new battery. Worked wonders for my phone.

Update #2:

Possible Solution for some users?

Well, as I stated in the last update, I finally did a factory restore of my daughters phone. We did not bother with a backup and just started with a new phone. 10.2.... not the Beta any longer.

Over a couple of hours the phone drained gradually from 100% down to 24%. There was no spontaneous shutdown at any point when the phone had been draining at what seemed a fast pace, but much much slower than we had been experiencing. By about 10:30 pm it had drained to 15%. Then by about 2am it was down to 9% when I went to bed.

I fully expected it to be dead when I got up at 8:30am, but to my surprise the phone was still on and said 6%. Impressive!

Then we were out all day with the phone sitting on the table to drain it out. Now at 2:30 it is showing 5%.

I don't know how long it will take to completely run out of power, but this is a promising sign. The phone has been on for about 28 hours now with no shutdown.

Perhaps in our case a recovery mode Factory Restore without re-installing from a backup has finally done the trick on this iPhone 5.

Anyhow, I feel the main issue now for our phone is that we need to somehow get the battery recalibrate so it will accurately show how much battery power is left.

Having to buy a new battery is an unacceptable solution to a clearly software issue.

I've been concerned about the charge initiation process being excessive , which it has been for users affected, will harm the battery. I wouldn't be surprised if we see a class action lawsuit pop up soon. I'm normally against them since their usually frivoulous but this seems like a legit reason IF it can be established the. Artery is being harmed.

Using a 6 plus. Never experienced the battery problem while I was on 10.1.

As soon as i updated to 10.2, my phone started shutting down at 40-50% battery remaining. I can't always have access to a charger while i'm outside so it's quite inconvienient. Apple please roll out an update which fixes this.

Thanks.

And that is why I am constantly replying on this thread because I only own an iPad Air 2 and an iPad mini that are experiencing similar issues. It's just that either other ipad users aren't experiencing this as I am, or they just don't know their are others with the same issues. There is currently no threads to this ipad group.

Though to note... Today, I unplugged from the charger and in less than an hour and a half the ipad went from 100% charged to completely drained. Oddly, at 10% is stayed there longer than at any time during the hour and a half. If I want to watch a movie on it, even plugged into a charger I lose battery power. 1 movie at 96 minutes will bring me down from 100% to somewhere in the lower 70%. That is while it is plugged into a charger. That don't seem weird to anyone other than myself?

And where were you six days ago and 12 pages back (from a PC desktop view)? That would've been helpful before I assumed the threatening message I received from an ominous evil source, indicating it "WAS" going to install the iOS 10.2 later that night between the hours of 12:00 and 3:00 A.M - while I remained ignorant, asleep, and totally unaware of its dastardly premeditated agenda- that it was too serious to ignore. And I did try to ignore that update (the one with the very bright fluorescent red screaming 'alert exclamation point' on the settings app) since everyone here who upgraded said it made the problem worse. And boy has it.

If only I had known...

Though, all is not lost since I will now, going forward, keep that little piece of knowledge close to the vest (or is that chest?). And perhaps wait several long months after an update before I ever decide that it's safe and okay to do so.

I was thinking more in the lines of this when I read the article:

"New iphones... Forget about the past. These new phones are better (*in a secret sideway whisper* a bit more expensive) that doesn't have the battery bug (or so we hope). Just get on down and fork over the money for a newer and longer lasting iphone... *Note the sarcasm here.

Sorry, I have a very dry sense of humor sometimes.

Maybe I should have inserted some crazy little emoji for effect on that last one...

I upgraded my iPhone 6s (which isn't showing the Shutdown issue) from iOS 10.1 to iOS 10.2 on Saturday morning at 9am (GMT) and following the upgrade to iOS 10.2, which I performed through the latest version of iTunes on OS X 10.11.6 (with the most recent Security Update), I have seen that my battery is draining much quicker than it did under iOS 10.1.

My iPhone has been sat on my desk, with the Mobile Data switched off (only connected to the network using a 2G connection), Bluetooth switched off, Location Services switched off and the WiFi switched off - for the last two days. So it isn't being used. In this time, it has lost 25% of the battery life. This is wildly worse than it was under iOS 10.1.

I have read the following article;

http://www.forbes.com/sites/gordonkelly/2016/12/21/apple-ios-10-2-iphone-battery -problems/#6cf3a89d4f2c

This seems to state that the battery performs better when a device is running the iOS 10.2.1 update, which is still in Beta. I'm not interested in installing a Beta on my phone. I've also asked @AppleSupport Twitter account a couple of times - once yesterday and again this afternoon and they have ignored both of the questions.

I also realize that this posting will just grow this thread... But I'm adding my voice...

I have a similar problem with my iPhone 6. I have had it for almost 2 years. It has iOS 9.3.4. since I haven't bothered to update it.

Battery zaps from 30ish to 1%. Then keeps on going for some more hours. If i plug it in, it bounces back 30ish.

It is sensitive to cold. If I hold the phone outside (10 degrees celsius) and away from the warmth of my pocket, it dies. If i plug it in (or heat it up a bit) it starts and comes back to the previous battery percentage.
