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.

Apple shared told TechCrunch that a good portion of the affected devices are seeing the issue solved with iOS 10.2.1, "After letting the fix simmer on customer devices, Apple now has statistics to share on how it has improved the issue, citing 80% reduction on iPhone 6S and 70% reduction on iPhone 6 devices."


It seems that this fix is only for the shutdown issue that popped up more recently. If you are still having unexpected shutdown issues and have had the update installed, it may be best to check your serial number on Apple’s website here in case a battery replacement is necessary.

Here is the full statement that Apple shared with TechCrunchWith iOS 10.2.1, Apple made improvements to reduce occurrences of unexpected shutdowns that a small number of users were experiencing with their iPhone. iOS 10.2.1 already has over 50% of active iOS devices upgraded and the diagnostic data we’ve received from upgraders shows that for this small percentage of users experiencing the issue, we’re seeing a more than 80% reduction in iPhone 6s and over 70% reduction on iPhone 6 of devices unexpectedly shutting down.

We also added the ability for the phone to restart without needing to connect to power, if a user still encounters an unexpected shutdown. It is important to note that these unexpected shutdowns are not a safety issue, but we understand it can be an inconvenience and wanted to fix the issue as quickly as possible. If a customer has any issues with their device they can contact AppleCare.
