MagSafe Battery Pack now provides 7.5W charging after firmware update

MagSafe Battery Pack

The firmware update was released on April 19 as an over-the-air update. While patch notes weren't provided at the time, Apple has since updated a support document to clarify that the update brings an improved charging rate.

"In order to get 7.5W charging on the go, update your MagSafe Battery Pack to the latest firmware," Apple writes. "The firmware update begins automatically after you attach your battery pack to your iPhone. The firmware update can take about one week."

Previously, the MagSafe Battery Pack topped out at 5W of charging — about the same as Apple's ubiquitous power brick that's no longer included with devices.

Users can check which firmware version they have on a connected iPhone by heading to Settings > General > About > MagSafe Battery Back. The firmware update that enables 7.5W charging is version 2.7.b.0.

Apple first launched the MagSafe Battery Pack in July 2021 for the iPhone 12, but it is also compatible with iPhone 13 devices. At the time, some users were disappointed by the charging speeds since other MagSafe accessories can provide up to 15W of charging output.
