On September 12th, Apple took its first steps toward full USB-C adoption. The company debuted its iPhone 15 lineup, which is fully equipped with USB-C, plus a new AirPods Pro case that utilizes the charging standard. However, it seems that some Apple products will not be included in this transition. Apple no longer sells the MagSafe Battery Pack or MagSafe Duo charging mat on its website — presumably, discontinuing these products is easier than upgrading them to USB-C.
