iPhone 6s promotional videoi battery 001

Many people are complaining about poor battery life after deploying the latest iOS 10.1.1 software update on their iPhone, which released for public consumption on October 31 and squashed bugs where Health data couldn’t be viewed for some users.

Aside from this, it seems that iOS 10.1.1 is also causing some iPhones to shut down abruptly when the battery charge falls below a certain percentage, according to a thread on Apple’s support forums that at post time had thirteen pages.

Multiple reports on Twitter and from the affected people who flocked to Apple’s discussion forums suggest that the problem affects many iPhone models, including the iPhone 6, iPhone 6s and even the latest iPhone 7 devices.

One user claims that turning off iOS 10’s new Raise to Wake feature has helped solve the problem, but I couldn’t verify this on one of the affected devices I own.

My iPhone 6s got plagued with this issue after upgrading to iOS 10.1.1.

As for my iPhone 7 Plus, it shows no signs of any battery woes whatsoever. For what it’s worth, I upgraded my iPhone 6s from iOS 9 to iOS 10 via an over-the-air update. As for my iPhone 7 Plus, I set it up as new rather than restore from a backup.

It’s possible that the cruft which inevitably gets accumulated from earlier iOS installations may be causing this. I always tell friends and family to install major iOS versions from scratch rather than upgrade in order to get the best performance, optimized battery life and as much free storage as possible.

I use my iPhone 6s much in the same way daily as I used to before updating to iOS 10.1.1 and it usually shuts down at some point after the battery falls below the fifty percent mark, typically around the 30+ percent mark.

After shutting down, the device won’t boot unless connected to its charger and shows an empty battery icon as if the battery charge was completely depleted. As soon as the phone boots, however, iOS’s status indicator shows the battery charge sitting comfortably above the 30 percent mark.

My iPhone 6s isn’t even among “a very small number” of devices manufactured between September and October 2015 that Apple has admitted may unexpectedly shut down and started offering a free repair program for.

After talking to a few local authorized service technicians, I was told that this is a known software issue in iOS which will be fixed in a future update.

Is your iPhone affected by this?

If so, we’d like to hear from you in the comments.

    I have a new iPod touch with the newest IOS. Its battery life is very poor. After 3 hours of use and 10 hours of standby it’s down to 20% battery remaining. I called Apple Care for help but their advice did not improve it. I now regret not just changing the battery in my 3 year old iPod touch.

    • leart

      pretty sure that there are tons of tips on Internet to improve at least 50% of your battery life, but you will not have all features on on the same time, if you can deal with that .. the battery life will dramatically improve

  • I’m not seeing this issue with mine.

  • Jared Steffen

    No battery issues at all on my iPhone 7. iPad mini 4 is fine too.

  • Zach Krase

    My phone randomly loses power and needs to be plugged in to turn back on. Quite annoying.

  • JulianZH

    people just over reacting.

    • YaBoyLilMayo

      Yea why should their $1000 not last a full day? They’re just overreacting, why should a product work like it’s supposed to?

      • leart

        had a bad day don’t you? lol

      • leart

        there are devices that have a explosive battery and can be hacked from kids lol

  • leart
    • YaBoyLilMayo

      It’s called a joke she’s not lying, how are you gonna tell someone else that their battery isn’t bad after updating? You fanboys are annoying af

      • Jeffrey

        Come on, leart is obviously also joking… You are the annoying one here.

      • leart

        if you are not having fun it’s your problem..mr.annoyed!

  • This is usually a sign that People have a Bad Battery.
    Bring it to the Genius Bar and let them perform a Battery Diagnostic.

    • Jose Rivera

      Exactly! I know for a fact a lot of people who use their phone like if it was attached to their body, and their battery life sucks so bad. I had a friend with a bloated iPhone 6 battery because he always had his phone on a charger due to Pokémon Go. His phone was just a week past his warranty too. A lot of people complaining about their battery life probably use their phone heavily.

  • Dexter

    I haven’t had any battery related issues on my 6S with iOS 10. However, my phone resprings a lot… I mean at least daily… sometimes while I’m using it and sometimes when it’s just sitting on my desk, locked. That’s my only gripe.

  • Jay Burgandy

    Mine is the haptic feedback/3D touch don’t work, even tho i restart the device after sometimes it will stop working never experienced this issue on previous iOS version.

    Some people saying it’s the Skype call that causing this bug. No idea about that fact.

    Kindly advice

  • Diego Milano

    Well, I know my comment will not be helpful nor will it apply to this, however I am waiting for an iOS 10 jailbreak to be released, and when this happens, my plan is to restore from scratch- yes, it may be time-consuming to get it all up and running from a blank device, but the benefits are too great to count.
    This has always been my practice and while many people reported issues of all sorts during upgrades, fortunately I never experienced any following this exercise. Try it yourself. 🙂

    • Niclas

      You should try Decipher Phone Refresh.
      I was in the same boat as you before I found this great tool 🙂

      • Diego Milano

        They do not recommend this for jailbroken devices though. 🙁 I still kind of enjoy doing this, believe it or not. 😀

      • Niclas

        Who doesen’t recommend it?
        I’ve used it while jailbroken with perfect results 🙂
        There’s also TiGi Apps Manager and PKGBackup. iMazing can do some cool stuff too.
        But I’ve had best results with Phone Refresh.

      • Diego Milano

        The company who created the tool doesn’t recommend it for jailbroken devices; who knows. Happy for you if it gives good results though.

      • Niclas

        Must be because it removes stuff that are not in vanilla installation making people complain over missing tweak settings.
        But to clean a jailbroken backup to only save certan parts of the backup it is perfect 🙂

      • Diego Milano

        I don’t care about losing the tweaks settings because I usually reinstall and reconfigure them from scratch after restoring, really the only “painful” part is re-adding the contacts (I know, I know, I could use iCloud, it’s just that I DISLIKE backups altogether cause I feel there’s old trash data being reinjected into my device, needless to say I could be wrong about this…).

      • Niclas

        Haha, ok. There are several ways to backup and restore contacts (iCloud is one, apps are another), “cleanly”.
        Where trash and problems can occur are in the settings and leftover or modified files that can get transfered to the backup, and the hard part is to create a fresh backup with all old app data (app data is low risk in terms of being “dirty”). Pretty much everything else is easy to backup and restore without risking to add “trash data” with the correct tools.

  • Pedro Cambron

    I thought I was the only one I turned off all background refresh and notifications because I thought that might have been affecting it but no it would still drain very quickly.

  • My battery is a bit more meh than usual and sometimes less. Hope this helps.

  • John

    Battery life on my iPhone 5 it’s actually better than expected with iOS 10.1.1. Phone last from early morning to 4-5pm when i arrive home with 10~20% left. Of course with light to moderate use, but for a 4y/o device, i think its pretty Good.

  • Jack Forsythe

    My 6 is having similar problems, will jump down in 10% increments quickly and often turn off at 40%. Sometimes it even drops to 1% even though when plugging back in it jumps back up.

  • Joaquim N.

    No battery issues after performing a DFU restore using the second build of IOS 10.1.1 on my iPhone 6s. No idea why since I keep the same settings, always.

  • diggitydang

    My 7 plus isn’t doing this, but my series one watch, I find, goes into battery saving mode a lot, even when there is plenty of battery. I have to reboot the watch to get it working properly again.

  • YES, battery issues on iPhone 6s Plus. Apple please wake up!!!

  • Jeffrey

    Thanks for the heads up! Definitely won’t be updating until a fix for this releases :).

  • DD™

    Having battery issues and random shutdowns on my out of warranty 6S. Apple replaced the battery at no charge.

  • Andrieux Querido

    iPhone 7 plus 128GB , no problems at all.

  • Drew

    Yes!! I thought I was the only one!
    About a week ago, my i6s Plus (on 10.1.1) shut down at around 42%. It then told me my phone was out of battery and that it needed a charger. I just plugged it on charge and the phone turned back on at the same battery percentage. My first instinct was to re-calibrate the battery. I did so, but it was still draining very poorly. Never experienced the abrupt shut down again though!

    I also discovered the 6s free repair program after my “shut down” experience, and went to Apple yesterday. The specialist told me this program doesnt apply to the Plus and that my battery was in passing range after running some diagnostics. Thanks to your article, Christian, I have now discovered it is a software issue.

  • ChrisLinke

    I’ve been experiencing this since iOS 10 beta 1. It’s not a real battery drain, but something is making iOS think the battery is lower than it actually is. A hard reset or plugging into power can fix it, but definitely something apple need to fix! (iPhone 6)

  • Bibibombibi

    Well, stop playing pokemon go and the battery will be much more lasting….. 😛

  • Shinonuke

    I am bringing my 6s 64gb in for repairs. Mine does this. Sometime I’ll have 40% battery life left and it’ll shutdown on me with icon that indicate it have to be plug in to turn on

  • Omkar Nagnur

    On a 6s and iOS 10.1.1 has given it the highest amount of battery life i have seen despite been affected by chipgate.

  • iPhone 6, battery draining since iOS 10. The latest update didn’t change much for me.

  • Aditya Bhatt

    Gets me through the day on my iPhone 7 (low power mode always on)

  • Brandon Angle

    Not one problem here. Iphone 7

  • nvog

    No noticeable issues on battery drain, BUT every instance of ios 10 so far (now on 10.1.1), still got not starting videos (safari, youtube, apps like imdb, streaming services etc.) after a couple of days use…. only way to resolve this, is by rebooting, and then again, after a couple of days… same thing.

    Something degenerates video playing service, and makes all videos unable to start.

    Using iPad air 2 and mini 4.

  • Thinker

    I’d comment from my iPhone, but the battery discharges too fast.

  • Riley Hay

    My battery life on my 7+ is about the same as it was with my 6s. Also liked how much less laggy iOS 9 was. On iOS 10, even with my new phone animations are extremely slow.

    • Diego Milano

      If you have an iPhone 7 Plus then it’s probably a software problem. Apple most likely will fix it if they haven’t already done so. 🙂

  • Cadrems

    This issue, without a shred of doubt, was caused by the iOS update.
    My Battery lasts 20 min at the most.
    The writer described my problem exactly. After updating to iOS 10.1.1:
    “After shutting down, the device won’t boot unless connected to its charger and shows an empty battery icon as if the battery charge was completely depleted. As soon as the phone boots, however, iOS’s status indicator shows the battery charge sitting comfortably above the 30 percent mark.”
    In my case, it often at 83%. It happens several times a day. I have to carry a portable external charger at ALL times.

    Unfortunately I’ve just purchased the Apple Watch 2 which is dependent on the iPhone (via Bluetooth). Using Bluetooth with this iOS 10 battery-draining bug is nearly impossible so in addition to the iphone problem, what I have is a very expensive and fairly useless Apple Watch until Apple decides to do the right thing and fix this iOS problem.
    I have attempted to follow all suggestions(turning off notifications, etc etc etc.) but they do not solve the problem.
    My iPhone 6 does not fall within their manufacturing date range nor is it under any warranty so it seems my phone does not qualify for any type repair which
    really, really galls me.
    We should not have to constantly carry an external portable battery charger so the phone will even work. This problem is not of our making. It’s a cumbersome mess that Apple needs to take care of.
    Why those manufacturing dates, and why is Apple disregarding or ignoring the massive number of users with this problem whose phones do NOT fall within the specified mfg dates?? What are we supposed to do and what CAN we do about this?
