Apple has released a new version 2.7 firmware update for its MagSafe battery pack that will charge your iPhone faster. It now offers 7.5W of on-the-go charging, up from 5W before the upgrade.
To charge 7.5W on the go, update your MagSafe battery to the latest firmware. The firmware update starts automatically after you connect the battery to iPhone. The firmware update may take about a week.
A week to update is quite a long time, but there is a faster way to update.
To update the firmware using a Mac or iPad, connect one end of the Lightning to USB cable to the Lightning connector on the battery and the other end to your Mac or iPad. The firmware update will take about 5 minutes.
The MagSafe battery is compatible with the iPhone 12 and 13 lines. Released in July 2021, it hasn’t been one of Apple’s most popular accessories. Due to its thick size, iPhone users were disappointed that it could only charge at 5W. However, it has been a bit popular with iPhone 12 Mini users as the biggest complaint about this device has been the short battery life. In general, charging with a good 20W power adapter is still faster, but the MagSafe battery is a good choice for mobile users.
