Apple is offering a $50 credit to customers who paid for an out-of-warranty battery replacement for iPhone 6 or later devices between January 1, 2017 and December 28, 2017. Eligible battery replacements were completed at an Apple authorized service location — Apple Store, Apple Repair Center, or an Apple Authorized Service Provider.

The credit will be provided as an electronic funds transfer or a credit on the credit card used to pay for the battery replacement service.
