iPhone 6s Unexpectedly Shuts Down? Apple Might Have a Fix!

Dec 3, 2016 - 19 Comments

iPhone 6s unexpectedly shuts down could indicate need for repair

Has your iPhone 6s randomly shut itself off for no obvious reason? Typically this happens when the iPhone 6s still has battery power available, but the device dies and powers down anyway. If this has happened to your iPhone 6s, it may be due to a battery failure and Apple might replace it for free.

To determine if your iPhone 6s is eligible for the free battery replacement, you’ll need to find the devices serial number and then run it through an Apple website for the “iPhone 6s Program for Unexpected Shutdown Issues”, here’s what you’ll want to do:

  1. Open the “Settings” app on your iPhone and then go to “General” and to “About” to locate the Serial Number for the iPhone 6s (you can also get the iPhone serial number from iTunes)
  2. Go to https://www.apple.com/support/iphone6s-unexpectedshutdown/ and enter the serial number of the iPhone to check eligibility

If the iPhone 6s serial number matches the range known to contain faulty batteries, you can send your iPhone 6s into Apple for a free repair. You can also take the iPhone into an Apple Store, or to a certified reseller or repair shop for the battery replacement as well.

Apple typically has a fast turnaround for mailing in a faulty iPhone for repair, so if your serial number falls into the range it is a good idea to send in the device for the battery replacement, even if you have not yet experienced a random shutdown or the device randomly turning itself off.

Remember, this specific program is limited to the iPhone 6s and a specific range of serial numbers. If your iPhone or iPad of any other model is exhibiting similar behavior of randomly turning off, follow this troubleshooting guide to see if you can remedy the issue on your own, and if that fails it may be a good idea to contact Apple Support.

    I feel sorry for you guys and my friend who just messaged me on her computer saying the phone just keeps shutting down. iPhone 6s as well. It’s under 1 year so I told her to take it to apple and don’t take no for an answer. Even if they turn it on make them fix the problem because her warranty is about to expire.

    I used to really like apple many years ago. When they refused to replace a display because of a dead-pixel (less than 30 days after purchase), I swore I would never buy an apple product. I do not believe in nor do I support a company who doesn’t care about it’s products or consumers. I ended returning approximately $7,000 of apple products that week. As of 10 years ago, I have never bought nor will I ever buy an apple product. But apple doesn’t care, because there will be many people who will just complain but do nothing but keep buying their products with the idea that maybe their next version will be worth it.

    Talk about brain wash marketing.

    I am facing the same issue on Iphone 6s Plus. Shuts down with battery remaining. My phone was under warranty when I first reported the issue to Apple.
    The software restore did not help. I demanded phone replacement.
    I spoke with a senior advisor at Apple who says they are aware of this issue but it is not a hardware issue. They are trying to find what in the software is causing this. He was telling me that they had replaced phones for some customers but the issue persists. So they are trying to figure out what the real issue is.
    All this for $$$$ that I paid for Apple’s product and service.
    My advise is- If you do not know whats wrong with your software-Stop selling your phones.
    I might file a complaint at Federal Trade Commission and all other places that I can.

    My iPhone 6s Plus has the same battery problem too ,since I updated my iPhone to IOS 10.1 ! So annoying to use this IPhone now! Shout down unexpectedly every single day when my battery still has 10%-50%!IPhone 6s and iPhone 6s Plus release at the same time, may use same battery! Why only iPhone 6s could replace battery?

  4. Gregoria Abella says:

    I have a problem with my iphone 6s when the battery is above 40% it automatically shuts I bought in March 2016

  5. Vitaliy says:

    The same thing with my iPhone 5s and iOS 9 since november or somewhen. So, the reason is not the iPhone 6s and/or iOS, but something else.

    Last week I went to apple since my 64gb iphone 6S had this exact problem, this start to happen a few times 1 or 2 weeks before. I explained the situation they checked my serial number, and since I had 2 more weeks left to use the phone’s guarantee.. they replaced me the Iphone with a brand new one. So if you still have guarantee time ask for phone replace not battery. Good Luck !

  7. Inconclusive says:

    Not without irony, Tony Faddel, the ex-Apple employee who built the iPod and worked on original iPhone, is having the same problems


    Also interesting that Tony Faddell is still using an iPhone 6s like so many other people, avoiding the 7


    Guess it was too early to ditch the headphone jack huh Apple?

    Time for Apple to go back to the best technologies that they used to have instead of making a fast buck with a lesser product. Very disappointed.

  9. Jan phelps says:

    I bought a new 6S last March, phone froze over and over and over, could not answer, slide would not work, went to Verizon five times, they kept resetting phone, finally called apple and they also reset along with making me do the 10.0 and 10.1 updates, made it worse. Got so mad went to ATT and wanted to get another brand but were out and only had the 7 so I paid Verizon for the stupid 6S and now have to pay for the 7. My 7 no problems at all with battery life, way better than 6S. Agree that Apple is getting messed up and maybe time to change. 1400.00 in phones and all I got for trade from ATT was 235.00 for a phone that I had still owed 458.00 on. Still had warranty obviously but the did not offer anything to repair or replace. Times getting tough for Apple?

    Great news, Apple replaced my phone for free today. My original phone was in the group of bad batteries. I called apple and made the appointment. They knew the serial number was part of the lot and they set up and appointment for me to have the battery swapped out while I waited in the store. When I get to my appointment, they did not have any battery kits left, so they swapped the phone. I am happy as can be.

    That’s great!
    Mine always shut down at 18%.
    The serial number you entered is not eligible under this program
    FCK Apple!!!!!!!

    My iPhone 6s Plus has the same problem but apple doesn’t cover it :(

    • good enuff says:

      I’d contact Apple anyway if I had a 6s that was having the problem. If you’ve owned it less than a year it’s under warranty anyway.

    My iPhone 6s is a better phone than my iPhone 7, which seems to drain battery faster than any iPhone I’ve had in years. But worth noting: there is also a bug or something in iOS 10.1.1 that is causing random shut downs when the battery is full, or the battery will rapidly drain and appear to shut down when actually the battery is just being rapidly depleted.

    It is separate from this problem, but iOS 10.1.1 is full of problems. Hopefully 10.2 fixes it pronto. My iPhone 7 has to be connected to a charger 3 different times a day.

    Apple is dropping the ball, very sloppy products and software lately. I wonder if they know it? I am faithful to Apple but I can’t help but feel like they’re becoming Microsoft in the early 2000s where they are so full of themselves they start releasing junk and eventually users will abandon ship for greener pastures. I hope they course correct quickly, but the newly weak MacTouchBarBook, iCloud messes, battery problems, software issues, all make me doubt where Apple is going. I read they don’t even have someone dedicated to annual Mac upgrade cycles! The 2nd biggest corp in the world doesn’t have someone dedicated to a $20 billion annual product line?? What are they doing over there in Cupertino?? Aye yeye.

    • Ken says:

      Agree with all your comments regarding Apple

    • townly says:

      iOS 10.2 also has random shut downs when the battery is full. its software bug or hardware bug ?

    • Simon says:

      Like you guys, I have a 6S+ sitting down randomly.

      I got my phone in October 2015.
      I first noticed problems back in late summer 2016, but it wasn’t often enough that it was a pain in the butt.
      So I thought, maybe I will get it looked at, except I didn’t follow up with more than a question to Apple (over the phone) and they said “update and restore to see if that helps”.
      Fast forward to Nov/Dec and it starts happening every other day and theres plenty of juice on the battery, and like an idiot, there I am finally, standing in an Apple store being told by a Tech that my “battery is fine”.
      So, “Go home, back up your phone and see if it keeps shutting down”.
      So I look online and see there are Soooooooo many people with the same problem.
      Absolutely pathetic reaction from Apple.
      Once upon a time, I thought I was paying TOP $$$$$$ for a quality product, backed by quality control and super customer service.
      When will they stop the fraud and admit to a systemic fault.
