iPhone 6 battery drain ios 10.2 problem

@hageme - any luck with replacing power management part? I have iPhone 6 with same issue. It's getting very annoying and frustrating.

I basically have the same problem with my 6s but I haven't tried the clean reset yet. For clarification, is that the resetting all settings or network settings? Hopefully if I do this then my battery won't stop draining like a leaky faucet.

I have an iPhone 6s, I had big battery problem (the famous 30% bug) since updating to iOS 10. After updating to iOS 10.2.1 problem not as big. Waiting now for iOS 10.3 when Inhope the problem will be solved completely.

I have the 6, and have had the same phone since it released almost 4 years ago. My battery dies randomly and can jump from 100 to 70 or lower. I will fall asleep with it on 100% and wake up to it being 84% or anything lower. I've let it die, restarted it, updated, and done research. It's the fact Apple is too cheap to simply fix the problem they created. I'm trying to wait for the 8 because the 7 is the same phone with a few more pixels in the camera. I'm disappointed with Apple the past few years for sure. Not even going into the random charges they apply every month tommy iTunes subscription.

I have been dealing with similar issues and had the same response as you did from Apple Support. I did a complete reset and restore from my iTunes backup and it helped for a few months and now I am back to having the same issues. I am also running the latest version. Now my battering percentage indicator is not synching with my battery, so I no longer have any idea how much battery remains. I will try contacting support by phone and see if I get any different answers and I will report back if I learn something. lol

I'm having similar problems. They battery percent will stay at 100% all day some days. Others it will stay at 100% for a few hours then start going down and some days its fine. Woke up this morning after leaving it charge all night and it says I have no battery and won't turn on. Super frustrating as I am leaving for a trip in 2 days and now have no phone.

It would be a complete reset and restore of your phone. Make sure you have it backed up before you do anything like that. I have the same issues. Did the reset a few months ago and now it is acting up again. Good luck!

Hopefully I am not too late and you have not already left for your trip. If you want to try doing a complete reset and restore of your phone that might work. It helped me for a few months and now it is acting up again. I found that the phone battery percentage is not always accurate so you may be fully charged and then the indicator shows you have nothing. I would try leaving the phone charged as much as possible and maybe getting a backup battery to take with you on your trip.

Just a heads up cos as I see that issue still persists. I had the same problem a few months a go and booked an appointment with the apple support. For those who have the iphone 6 and iOS 10.2 and above the news are bad. I think my phone was running iOS10.2 when I went to the suppot and I was told that there is an issue with the battery management on the iOS which effects all the iphone 6 devices and a few 6s. The only solution was to replace my phone with a new one which its running 10.1. Since then I haven'y upgraded yet. According to Support, the engineers haven't figured out what it causes the issue yet. NOT sure if the 10.3.x will fix the issue but I am not satisfied at all sio far with the phone.

Thanks. Will be checking to see what they say at the Apple store next week and will let everyone know what I find out. I also had a feeling this may have something to do with the recent iOS updates.

I ended up just going in and having a new battery put in as there wasn't much else to do. I had been charging it as much as possible which was working until that morning when it didn't think it had charged at all and wouldn't turn on. The guy who replaced it said there was a crack in the battery itself when he opened it up so not sure if that was somehow causing the issue. I've barely dropped that phone and it's always in its case and not even 2 years old so disappointed to have to replace the battery already but at least it's working now.

Same problem: iPhone 6 purchased December 2014. Issues started December 2016, about 2 weeks after contract ended. Just that I have never updated to IOS 10. It is still running on IOS 9.3.2. No Apple Store in Luxembourg. In Post office where I bought it, I was told: make a new contract, and take an iPhone 7! I want to wait for next one. My iPhone will, after having charged and with 100% battery life, shut down after 1 - 1,5 hours of medium use. When I start charging it will jump to usually something between 40-70%. Sometimes it is even shutting down still showing 80%. It happened also that after a night of charging it just showed 30%, but 1 hour later showed suddenly 100%. I cannot go anywhere without an extern battery.

I had already the same issue with iPhone 5. For this one nevertheless the battery was exchanged free.
