Last year after Apple admitted that they were throttling older iPhones with degraded batteries, they launched a battery replacement program where they discounted the price of replacements from $79 to $29 as a way to make up for it. However what about those who have replaced their batteries prior to this?
The good news is that Apple is offering refund for those customers as well, according to this support document spotted by the folks at 9to5Mac. The $50 is basically the difference between the original price of a battery replacement and the current offer, so if you are one of the eligible customers, Apple claims that they will be contacting you via email to let you know how to obtain the credit, which will be given via electronic funds transfer or credit towards the credit card you used to pay for the replacement.
According to Apple, “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.”
Prior to this there have been talks that Apple could be considering a refund and that customers could request it, but now it looks like Apple is proactively offering refunds to eligible customers.
