MagSafe Battery Pack gets a mysterious firmware update
Apple issued new firmware for its MagSafe Battery accessory for iPhone Air, designated version 99.0 (8B25), superseding version 91.0 (8A351). This update was subsequently retracted by Apple; the specific reason for its withdrawal and potential re-release timeline remain unstated.
The firmware update for the MagSafe Battery, an accessory for the iPhone Air, was noted by Aaron Perris on X on December 3, 2025. Details regarding the functional changes introduced by this firmware remain unspecified, although improvements in compatibility with iOS or the iPhone Air are presumed. Accessory firmware updates typically install automatically during device usage, without a manual trigger option.
This release follows other recent firmware updates from Apple for various accessories last month. These included new firmware for the Magic Keyboard with USB-C, the Magic Trackpad, and a power adapter.
