Apple has released an update for its MagSafe battery pack that unlocks a faster charging speed for iPhones. While the MagSafe battery pack initially offered 5W charging, the update allows users to unlock a faster 7.5W charging speed, for iPhone 12 and iPhone 13 models.
Apple says that:
“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.”
How to charge the MagSafe battery pack?
Plug one end of a Lightning to USB cable into the Lightning connector on the MagSafe Battery Pack.
Plug the other end of the cable into a 20W or higher USB power adapter, then plug the adapter into a power outlet. The status light on MagSafe Battery Pack will stay lit for about 8 seconds.
Charge until the battery pack flashes green light.
Apple launched the MagSafe Battery Pack in July 2021. It is an accessory that provides additional battery life for iPhone 12 and iPhone 13 models. It attaches to the back of an iPhone via MagSafe technology.
Back then, the accessory was able to charge iPhones with a 5W charging speed, which in comparison to today’s fast charging speeds of 65W and 120W seems outdated.
