Late last year, Apple began offering $29 battery replacements to customers with an iPhone 6 or later. Now the company has confirmed that it's taking care of customers who got a battery replacement before that offer went into effect.
Apple is giving a $50 credit to customers who paid for an out-of-warranty battery replacement for their iPhone 6 or later. This offer is available to customers who got their battery replaced between January 1, 2017 and December 28, 2017 at an Apple Store, Apple Repair Center, or Apple Authorized Service Provider.
Apple is emailing customers who are eligible for this $50 credit, which will be given as an electronic funds transfer or credit on the credit card used to pay for the battery replacement. Customers will be contacted between May 23, 2018 and July 27, 2018.
It's good to see Apple refunding the difference of its normal battery replacement price and its discounted price for affected customers. Some people decided to get the battery in their iPhone 6 or later replaced right away to try and fix their slowing phones, and those people shouldn't have to pay more to get the same issue fixed that's now being covered by the cheaper battery replacement offer.
