iOS 10.1 Battery drain

Perhaps some good news - Battery Replacement Programme Launched for iPhone 6S - ABOUT TIME !!!!!!

http://www.macrumors.com/2016/11/20/iphone-6s-shutdown-repair-program/

Still, how come this only started happening in a lot of iPhones after installing 10.1.1? I did three clean installs of 10.1 and now, finally, my iPhone 6s is working better than ever. I have 6 hrs of usage and almost 50 hours of standby and still 17% battery left. But what will happen if I upgrade to 10.1.1? In other words: aren't there two separate issues: random shutdowns and battery drainage? One related to battery and one to firmware/software?

Hi from Italy, i have a iphone 6 with ios10.1.1.

I have drain from battery very quick, from 100% to 30% in 3 hours without using it and then it switch off ...

I am in contact with apple care support from 3 weeks it seems they know everything but they want to make the time pass away to gain time for ios 10.2.

They have released an update that fuckedup our phones ... very very disgusted about this

It is strange. As I read the posts, it looks this is not a battery related issue. I mean most of the people here have problem with the battery since the Ios 10.1 installed. I think changing the battery will not solve the problem. (Except if the ios 10.1 killed the battery)

Btw with a clean install of ios 10.1 my 6s isnt shutfing down randomly, still battery is draining fast

Ok so I tried turning Find My iPhone and all the others from the iCloud settings off, and now my battery seems fine, no weird fast drains anymore.

Exactly Same issue with me too.

Tried restoring factory settings - didn't help.

~ What I found - if I disable the "Cellular data" - the phone battery is behaving very normal. So it is definitely not a hardware (battery) problem.

~ Then I enabled the cellular data - but disabled all individual apps data. Then also behaving Normal.

~ Then I tried to enable one by one apps cellular data options as & when I needed them. It's still now working fine (enabled only WhatsApp, Facebook, Phone, Vonage Extension, BofA & Chrome).

I'm not sure yet but seems like Safari App may be the main culprit here due to 10.1.1 upgrade. Right now I'm using Google chrome for browsing and it is working good. But for sure - my iPhone is not smart enough :(

Finally apple has officially admitted to this problem and wil be replacing batteries for those affected.

Please see:

I will be bringing mine to the Apple Store as soon as they can get me booked in.

Same issue here with my wife's iPhone 6 - shutdowns randomly indicating out of power after upgrading to 10.1.1 -

I rolled back to 10.1 last night, installed only what's necessary and still seeing shutdowns (however, less frequent).

This is crazy. The fact that we haven't jump through all of these hoops is indication of poor quality control and lousy testing. It appears apple only tests thoroughly on the latest hardware and then trickles down to older hardware if they feel like it. So while everyone complains about fragmentation on android I would rather have firmware that works then upgrade to the latest version that hasn't been tested or doesn't work.

What a lousy service by Apple!

Since upgrading to 10.1.1 some weeks ago my colleagues are storming our IT service center. They are not even able to make their phone calls through the day. It's absolutely inappropriate how Apple acts.

To make things worse bluetooth devices (headsets, car audio etc.) aren't working fine since 10.1.1. How can we expect from BMW, Mercedes and VW to update their software if it worked before? This is Apple's request to our problems...

As a consequence of this our IT Managing Director decided just now to shift all of our ios devices to Android devices. Ok, we only have 500 apple devices running at this moment, but this is at least our contribute to a failed service policy by Apple.

Yes, it is very kind from Apple. But the problem is not the battery. It looks the problem is the new iOS above 10.1. Nobody had problem with iOS 9 or iOS 10, only after installed the 10.1.

So I still think replacing the battery is not the solution. The really f*cked up something with iOS 10.1. They sholud fix that first.

Also many people have problem with Iphone 5(s) and Iphone 7 as well.

My Iphone 5s went down from 100% to 60% in 2 hours without ANY use. I mean no sim card, no wireless, no app installed, no any network connection. Before, it worked for 2 days on iOS 10.0.2(and iOS 9) with normal use(Wifi, mobile network....).

I hope they fix this soon...

Interestingly I also identified this problem on my iPhone 7, and it only has 7 days of use, unfortunately I'm already having a bad experience with the new iPhone 7, although the problem is only iOS 10.1.1 should fix this urgently.

Well tell that to Apple who finally replaced my iPhone 6s today, yes that is correct replaced the phone and not just the battery.

I don't wish to preseume the Root cause here and believe Apple know a little more through Root Cause Analysis RCA than me.

From my observation my two two phones one perfectly working iPhone 5 on 10.1.1 and one great expensive but very aesthetic paperweight iPhone 6s on 10.1.1, it would appear consistent with the Apple press release that the phone 6s had a Fault. The two phones obviously get slightly different versions of the same generation of the iOS software.

I had jumped through all of the hoops of multiple resetting permutations and this was my second Genius Bar appointment after having spoke with apple care also earlier today.

My serial number was not identified as being affected but I could demonstrate from the history with Apple care that this was occuring to my phone.

Apple had case noted from my first genius appointment over a week ago and the diagnostic test results from the Genius Bar appointment and also the diagnostic results from my Apple care calls too.

This showed that my battery was not worn, and supposedly good but could prove that it was discharging abnormally.

I had tried downgrading to 10.1, the re tried 10.1.1 then installed the Dec beta 10.2 ver3. And all of these firmwares had the issue.

The best was 10.2 beta for reduced battery drain but it still shut off randomly.

So I will trial my new iPhone 6s for a few days and see how it performs. Best of luck to everyone else.

I'm having an issue where my battery will just drain without any apps running. I checked my settings and saw that Apple Music has been running 6.5hrs worth of background apps. Not sure if that's the culprit, or if there's a way to shut down background apps. My phone dropped from 80, to 50, to 19 percent battery life today. Never had these issues prior to the update.
