If you have MagSafe Duo, there is a new firmware version for your device. Unfortunately, it won’t fix anything that’s wrong with it.
As MacRumors noted, the new version is 256.1067.0 (10M3063). To check, connect your iPhone to the MagSafe Duo charger, open the Settings app, tap Generalthen ABOUTAnd carrier lock. Then select the name “Apple MagSafe Charger” and you will see the firmware version number. The previous firmware number was 184.108.40.206.
Unfortunately, the new firmware will not fix any of the MagSafe Duo’s current issues. When it launched in 2020, we called it “virtually impossible to recommend” in our 2-star review, complaining about its slow speed and clunky design, and things have only gotten worse over the years. The iPhone 14 Pro and Pro Max are hard to fit into the charger, and Apple recommends laying the Apple Watch Ultra flat and removing the strap to allow it to charge properly, as it doesn’t fit properly in the vertical position.
It’s not possible to physically update the MagSafe Duo firmware, but if it’s plugged in and charging your Apple device, it should automatically download and install the update.
