iPhone 6s Colors

Two weeks ago, Apple issued a global battery replacement program to address a problem where some iPhone 6s handsets manufactured between September and October 2015 may unexpectedly shut down (see if your phone is eligible for a free battery via Apple’s web tool).

While the company originally did not say why these devices are shutting down when the battery indicator drops below the 30 percent mark, MacRumors points us to a message posted in a support document on Apple’s website in China which blames the problem on a manufacturing issue.

The company has said that the issue is related to some batteries having been overexposed to “controlled ambient air” during the manufacturing process, causing them to “degrade faster” than usual.

Here’s Apple’s message in its entirety:

We found that a small number of iPhone 6s devices made in September and October 2015 contained a battery component that was exposed to controlled ambient air longer than it should have been before being assembled into battery packs. As a result, these batteries degrade faster than a normal battery and cause unexpected shutdowns to occur. It’s important to note, this is not a safety issue.

If your device is eligible for a free battery replacement, contact your nearest Apple retail store or an authorized service provider. Folks who have already paid to have their eligible iPhone 6s battery repaired or replaced can contact Apple Support regarding a refund.

    Title says “buttery” shutdowns

  • Wiley

  • Cristian

    Would I have any luck by just waking in without making an appointment? My appointment’s not till Thursday and my battery is just so terrible

      You can take a chance, but as busy as these stores are… you may end up waiting a long time to be seen. You could try an authorized apple repair center.

        I went to Best Buy as a apple authorized repair and I don’t recommend it, the guy did a diagnostic and said it came out Okay battery health was good, only issue was I had a lot of background activity and im like really 100% batter goes to 50% then shuts off and tells me to plug it in really! They don’t know what there doing.

    Shame it’s only the 6S because I get this on the 6.

  • malhal

    At least now we know it has nothing to do with iOS 10.1

  • BooBee

    My 6S had been doing that for a few months now of which Apple techs kept telling me the battery was fine. They took my phone error logs, made me re-install iOS to no avail. I finally just upgraded to an iPhone 7 and traded the defect back to Verizon.


    Also iPhone 6 and 6Plus have the same issue

  • Better to shut down than to blow up is what I always say.

    So much for quality control. So what about touch disease? Why are they charging $150 to fix that?

  • Jeiivy

    No luck at Apple

  • Wilber Alexander Flores

    Does this include the plus? Because mine did it a week ago at 20% and it’s from the first batch that went out on release day
