Smart Battery Case

The iPhone Smart Battery Case is a series of accessories designed by Apple to provide supplemental power to selected iPhone models in a protective case.

History
The Smart Battery Case was first released in 2015 for the iPhone 6 and 6 S series. The "bump" for the battery on the back of the case received a mixed reaction. Versions for the iPhone 8 and X were never released. The cases are designed for specific models and are generally not completely compatible with one another. For example, the case for the iPhone 7 will cover up the headphone jack of an iPhone 6.

In January 2020, Apple initiated a Smart Battery Case replacement program for owners of cases for the iPhone X R, X S , and X S Max. With the release of the iPhone 12 series in late 2020, which added support for wireless MagSafe charging, Smart Battery Cases have been superseded by the MagSafe Battery Pack.
