Apple has announced it is offering to replace batteries free of charge for 6S iPhones with a shutdown problem.
They released the following statement:
Apple has determined that a very small number of iPhone 6s devices may unexpectedly shut down. This is not a safety issue and only affects devices within a limited serial number range that were manufactured between September and October 2015.
If you have experienced this issue, please visit an Apple Retail Store or an Apple Authorized Service Provider and have your device’s serial number checked to confirm eligibility for a battery replacement, free of charge.
Choose one of the service options below to have your battery replaced. Your iPhone will be examined prior to any service to verify that it is eligible for this program and in working order.
Please call your service provider to confirm that battery replacement service is available on the day you visit them.
Apple Authorized Service Provider – Find one here.
Apple Retail Store – Make an appointment here.

Note: Wireless carrier partners are not participating in this program.
To prepare your iPhone 6s for the battery replacement process, please follow the steps below:
Back up your data to iTunes or iCloud.
Turn off Find my iPhone
Erase data and settings in Settings > General > Reset > Erase all Content and Settings
Note: If your iPhone 6s has any damage such as a cracked screen which impairs the replacement of the battery, that issue will need to be resolved prior to the battery replacement. In some cases, there may be a cost associated with the repair.
Apple may restrict or limit repair to the original country of purchase.
If you believe your iPhone 6s was affected by this issue, and you paid to replace your battery, you can contact Apple about a refund.
This worldwide Apple program doesn’t extend the standard warranty coverage of the iPhone 6s.
The program covers affected iPhone 6s batteries for 3 years after the first retail sale of the unit.
