When we reviewed the MagSafe Battery Pack earlier this year, one of our biggest complaints was that it was underpowered compared to its rivals, only charging at 5W compared to 7.5W for less intelligent battery packs. After an update of firmware, Apple has unlocked faster charging for all models.
Apple has announced that version 2.7 of the firmwarewhich was released earlier this week, unlocks 7.5W charging on the go for all iPhone 12 and iPhone 13 models. Plus, you can still get up to 15W charging when the battery pack is connected to a 20W or higher power supply.
You can update the firmware In two ways. When the battery pack is connected to your iPhone, it automatically begins this process, though Apple says it could take up to a week to install. You can also update the firmware using a Mac or iPad by plugging one end of a Lightning to USB cable into the Lightning connector on your battery and the other end into the USB-C port on your Mac or iPad. Apple says this method will take about 5 minutes.
The MagSafe Battery Pack went on sale in June 2021, several months after the launch of the iPhone 12. It retails for €103.99 and has a battery capacity of 1,460 mAh, which is not enough to fully charge any iPhone 12. or 13, but that will allow you to get a few more hours of battery life.
