Currently, battery health metrics such as maximum capacity and cycle count are not presented to consumers whose devices have third-party batteries. This is because the accuracy of these metrics cannot be verified by Apple. In fact, an Apple internal analysis has found that some third-party batteries sold as new are actually secondhand, with battery health metrics manipulated to appear as new. In an effort to improve support for third-party batteries, starting later in 2024, Apple will display battery health metrics with a notification stating that Apple cannot verify the information presented.
