Apple will be giving $80 credit to those who bought an out-of-warranty battery replacement for an iPhone 6 or later between January 1 2017 and December 28 2017.
The credit will be given to those who purchased the battery at an Apple authorised service location.
The money will be sent via electronic funds transfer or the credit card used to pay for the warranty.
Eligible customers will be contacted between May 23 and July 27.
Apple says if someone believes they are eligible for the credit and didn’t receive an email to contact Apple before December 31.
For 2018 only, Apple has reduced the price of its iPhone batteries and in Australia they dropped from $119 to $39. This discount comes after allegations that Apple purposely slows down its iPhones so customers have to constantly upgrade.
