Apple attaches great importance to every customer, especially their questions about Apple products. After learning the unexpected shutdown of iPhone users, we conducted a thorough investigation, collection of equipment and analysis.

It is worth emphasizing that this is not a security issue.
To help customers solve this problem, we replace the batteries for the affected devices free of charge. IPhone 6s users can enter the device serial number on the iPhone 6s unexpected shutdown plan page to see if their devices meet the criteria for free replacement of the battery. We apologize for any inconvenience this may cause to our customers.

Some situations in which an automatic shutdown occurs may be unexpected for the customer, but this is designed to protect the electronic components from damage due to low voltages.
