Apple MagSafe Battery Pack Firmware Receives Update From Apple.
Apple updates MagSafe battery pack

The MagSafe Battery Pack looks to have been upgraded by Apple to work with the iPhone 12 and iPhone 13 devices that accept MagSafe accessories.
Customers with MagSafe Battery Packs should notice a 2.7.b.0 version number in the Settings app after installing the new firmware, which should be available over-the-air beginning today.

The MagSafe Battery Pack firmware was last updated in December, and the previous version was 2.5.b.0. “
