Apple’s new firmware for MagSafe Battery Pack supports 7.5W wireless charging
Among the many MagSafe accessories for iPhone, Apple MagSafe Battery Pack is a very practical magnetic mobile power supply, but its actual use experience is average. The biggest problem is that the charging speed is very slow, which is not the same as Smart Battery Case, but what everyone didn’t expect is that this product can actually improve the charging speed through a firmware upgrade.

9to5Mac found from Apple’s official website product support page, MagSafe Battery Pack can get 7.5W wireless charging power by upgrading the firmware to version 2.7, while the original maximum charging power is only 5W. This also causes many people to run a high-load app, and the MagSafe external battery may not be replenished as fast as the iPhone’s power consumption.However, upgrading this new version of the firmware is more incredible. Apple said that after the MagSafe Battery Pack is magnetically attracted to the iPhone, it will automatically start to upgrade the new firmware, but it will take a week.
Apple writes:
In order to get 7.5W charging on the go, update your MagSafe Battery Pack to the latest firmware. The firmware update begins automatically after you attach your battery pack to your iPhone. The firmware update can take about one week.
