Memo from Apple: $29 Battery replacements available for all included iPhone models with no delay?
Models from the iPhone 6 and later qualify for the $29 battery replacement
There is good news today, and it comes from an internal Apple memo dated April 27th, which was obtained by MacRumors. The memo was sent to Apple Stores and Apple Authorized Service Providers and says that "service inventory of all iPhone replacement batteries is now available without delay."
The battery replacement program, born of controversy, also has some issues of its own. Earlier this month, we told you that the BBC discovered that U.K. Apple Stores are using a technicality to force iPhone owners to make expensive repairs on their devices before getting the discounted battery replacement taken care of.
In iOS 11.3, Apple included a meter that allows iPhone users to monitor the health of their battery. It also allows them to disable the throttling of their phone's CPU, even if they have yet to replace the battery powering their unit.
