iOS 10.1 Battery drain

May I assume, then, that you did not have these problems on iOS 10.0.3? If that's the case, seeing as you are quite sure the battery is fine, I'd identify this as a firmware issue and suggest doing a downgrade to 10.0.3, if no one else provides further suggestions.

Before all that, if you didn't already, I'd recommend doing a soft reset (holding together the Home and Power buttons until the phone reboots and the Apple logo shows up) and checking the number of cycles your battery has (e.g.: using your pc or Mac), just in case the update to 10.1 isn't coincidental to the battery problems.

I'm seeing this too since the upgrade.. I use my iPhone in the same way daily and in the hour I use it on the train in to work I can get down to 35% from 100%.

Since the upgrade to 10.1 my iphone 6s battery is draining pretty quick. Most of the battery use is by the Music app in the background and I can't seem to find a setting to disable the music app from running in the background.

I'm having the identical issue after upgrading yesterday to 10.1.1...battery suddenly dies at 30%...I have no idea why...I even did a full wipe and it's still doing it...I'm using a 6S and my phone is only like 6 momths old and was working perfectly before the upgrade.

I upgraded to 10.1.1 this morning on my iPhone 6s Plus. I am now seeing the same thing others are seeing. The battery started dropping really quickly on my commute home from work (35 minutes today) from about 70% to suddenly I get a 20% low power notification. Within 10 minutes, it was down to 4% remaining. Unlike others, rebooting the phone didn't restore the power...it was still at 4%. Very very unhappy.

I should point out that the so called upgrade this morning took a very very long time...probably 30 minutes. Going from 10.0.3 to 10.1 only took perhaps 10 minutes.

Ditto here since I downloaded yesterday. Was on chat with Apple Support. They tested my battery health and it's fine but said that several people have reported this issue and their engineering team is working on an update to resolve the problem. Hopefully it will be soon!

It should be noted that I didn't experience the drain today...strange...I charged it to full this morning and it's running good all day...I'm at 51% now so I'll keep an eye on it when it hits the low 30s.

Go to settings > General > Background App Refresh > Turn Music Off. This will disable refresh in the background.

I have the same issue when I upgraded to iOs10.1, the battery drains pretty quick unlike before in iOs 10.0.2 or previous version. I can see the battery percentage drops drastically while I'm using my iPhone in a short period of time.

I have never encountered this issue before. Last time when I fully charged my iPhone before going to sleep its normal that its still have 100% when i check in the morning. But its a different story now, it drops to 90% overnight. there also an instance that I still have 28% then drops to 6% while browsing the internet.

I just recently upgraded to iOs 10.1.1 and hoping that the issue will be solve, but I'm disappointed . So I'm pretty sure that this is a Os problem and hoping they could solve this ASAP.

I'm having this same issue. From a 100% charge I'm getting about 2 hours of battery life with ZERO usage during the 2 hours. This all began after I installed the software update 10.1.1. Never once did I encounter this battery life issue previously. I'm operating a new iPhone 7. Oddly I am also being continually prompted to verify my apple ID on my device. This is proving to be extremely irritating and I simply cannot use my phone as needed; to maintain power I must keep it plugged in to a power source. I will be taking the device into the Genius Bar in hopes they can solve this issue.

Praying for a software update fix to be released ASAP!

Try doing a full wipe...I did that and think that fixed it for me...I'm using a 6S though...I don't think its background refresh issues either...my phone kept doing this until I did a full clean wipe and started over...I have had the issue since...I'm on my 4th full recharge now.

Hey Iphone Love....Please Solve the Battrey Issue. ios 10.1.1 its not Proper Work.and Bettry Issue...Thanks

Music isn't included in Backgroup App Refresh. Maybe that's the problem?

The issues I was having with battery drain seem to be resolved with the 10.1.1 update.
