    For the last several months, iPhone 6, 6s, 6 Plus, and 6s Plus users have been dealing with a problem that causes their devices to unexpectedly shut down, an issue that Apple now says it has successfully addressed in the latest iOS 10.2.1 update, released to the public on January 23.

    In a statement provided to TechCrunch, Apple says that the iOS 10.2.1 update has resulted in an 80 percent reduction of unexpected shutdowns on the iPhone 6s and a 70 percent reduction of unexpected shutdowns on the iPhone 6.

    According to Apple, the shutdown issue that is solved by the iOS 10.2.1 update is separate from the problem that caused it to recall a select number of iPhone 6s devices. In that case, Apple said some batteries had been overexposed to "controlled ambient air" during the manufacturing process, resulting in the need for a physical battery replacement.

    That there are multiple issues causing iPhone shutdowns explains why many iPhone 6 users also complained of problems after the iPhone 6s recall, and why the iPhone 6s issue seemed more widespread than Apple suggested in the recall program. There were even rumors that Apple was planning an iPhone 6 battery exchange program, something Apple quickly refuted.

    The shutdowns solved by iOS 10.2.1 are reportedly caused by uneven power delivery from older batteries, which can trigger an emergency shutdown on an iPhone. Apple has tweaked its power management system to reduce shutdowns, but some users may occasionally still have problems, so Apple has also created a way to auto-restart without needing to connect to power. The auto-restart feature is available on the iPhone 6 and 6s in iOS 10.2.1 and will be added to the iPhone 6 Plus and 6s Plus in iOS 10.3.

    A new battery info screen will also be added to iOS 10.2.1 in the next few days, letting customers who need to replace their battery know that it's not functioning as expected. The warning, which will be in the Battery section of the Settings app, will only be displayed to customers who need new batteries.

    When iOS 10.2.1 was released, Apple did not include a mention of a fix for the iPhone 6 and 6s in its release notes, giving it time to quietly collect data on the shutdown issue before making an official announcement. Customers who are experiencing shutdowns on their iPhone 6 or 6s devices should upgrade to iOS 10.2.1 if they have not done so already.

    Update: Apple has posted a support document outlining the new battery notice that's available in the Settings app. It will only show up if a battery needs servicing.

    Now, when will they address the random restarts that happen on the iPhone 7 Plus almost on a daily basis? That's also annoying and inconvenient as hell.

    I want to go back to iOS 10.0 or 10.0x or something. My iphone 6 plus has become so laggy in last couple of months.

    um, the only thing that stopped my 6s+ from crashing @60% charge was paying Apple to replace the battery...

    Lol. I had mine replaced under the recall for the 6S and it still shuts down randomly.

    Pff this could be fixed on iOS 9 already - with a jailbreak tweak.

    except it didn't effect the majority of their phone. It didn't affect mine and I got the 6s.

    Haven't had random restart issues since 10.0. Have you tried a factory reset/setup as new? If you have, then it's time to take advantage of that warranty because that's not normal.

    I am still waiting for the fix to my iPad Mini that I regrettably upgraded to iOS 10.

    It runs like a turd, especially in safari. It is so laggy when scrolling and typing.

    No way in hell am I upgrading my iPhone 6s Plus to iOS 10.

    my power-related unexpected shutdowns on my iPhone 6 have gotten worse since iOS 10.2.1 :(

    Actually they did address the touch disease:
    Granted, it's a repair program and not a recall, which is kind of sketchy.

    I've heard iOS 10 runs well on the 6s, and 10.3 is supposedly a lot faster.

    Sadly, you can expect more of these type of bugs as most of the test team was drafted to the EMOJI DESIGN TEAM.
