Apple has issued a statement on the iPhone 6S unexpected shutdown issue post the iOS 10 launch and update.
Users all over the world have noticed their iPhone 6S would automatically turn off when the battery level reached 20% or 30%. This glitch would not be triggered by any particular application or use case.
Apple issued the following statement to its customers:
We care deeply about our customers and take seriously concerns they have about their Apple products. After hearing reports from iPhone customers whose devices unexpectedly shut down, we thoroughly looked into these reports, and collected and analyzed devices.
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.
To help our customers who are experiencing this issue, we are replacing batteries in affected devices, free of charge. iPhone 6s owners can easily find out if their device is eligible by typing in their device’s serial number on the iPhone 6s Program for Unexpected Shutdown Issues web page. We apologize for any inconvenience this has caused customers.
We also want our customers to know that an iPhone is actually designed to shut down automatically under certain conditions, such as extremely cold temperature. To an iPhone user, some of those shutdowns might seem unexpected, but they are designed to protect the device’s electronics from low voltage.
We looked for any other factors that could cause an iPhone to shut down unexpectedly. After intensive investigations, no new factors have been identified. We will continue to monitor and analyze customer reports.
We encourage any customer who experiences an issue with an Apple product to visit an Apple Store or an Apple Authorized Service Provider, or to contact Apple Support.
Technouz readers have told us that Apple Store representatives have said that the issue may be caused by the battery not holding full charge. This caused selected models of the iPhone 6 to shut down at around 20%.
Users could charge the device for thirty seconds and continue using as normal even after the iPhone 6S unexpected shutdown.
The glitch has been caused by the recent update to iOS 10 – Apple’s latest mobile operating system for iPhones and iPads. The issue has not been reported for any devices outside of the iPhone 6S.
The issue only affects select models manufactured between September 2015 and October 2015.
