The reduced pricing applies to anyone with an iPhone 6 or later whose battery needs to be replaced, starting in late January 2018.
Apple also said it would soon issue a software update with new features that would allow users to more clearly see the health of their iPhone's battery.
It follows the tech giant's admission that they deliberately slowed down the processing power of iPhones with older batteries using iOS updates. It's still sticking to its guns about why it chose to throttle performance in the first place, but there is a silver lining in that it's offering a $50 discount for out-of-warranty battery replacements.
You need to take your iPhone into an Apple store or contact its online support team to book a fix. Apple's statement and reports from bloggers helped fuel conspiracy theories Apple is intentionally slowing down its products to fuel sales.
In a new statement released last night, Apple have now apologised and said it was aware some of its customers feel they have been let down.
In order to address the customer concerns, the firm is cutting battery replacement costs to just $29, from $79, for out of warranty devices.
Apple also noted that it will give users more visibility into the healthy of their phone battery in an iOS update in 2018.
In its letter, Apple says there's "been a lot of misunderstanding about this issue", adding that it had not been seeking to "degrade the user experience to drive customer upgrades".
Apple said at first it believed such performance loss was due to a combination of factors, including "a normal, temporary performance impact" when upgrading the operating system and minor bugs.
