You think Apple has fixed this ‘issue?’ Nope. The USB-C port is under the Magic Mouse, exactly where the Lightning port was.
Apple hasn’t Changed how the Magic Mouse Charges – the USB-C Port is Under the Mouse and Requires You to Flip it Before Charging
I honestly don’t care how the Magic Mouse charges. Whether it’s upside down or sideways, I charge the mouse randomly before turning off my Mac. This way, the battery stays topped up and I don’t have to worry about power, ever.
However, for some people, it’s important how the Magic Mouse charges. Today, the famous accessory got its much-awaited upgrade and now has a USB-C port. This new port is exactly where Lightning was which means you’ll be charging the mouse upside down whenever you have to.
Do keep in mind the Magic Mouse that ships with the new iMac is exactly the same as the one you buy separately. The only difference is the iMac one is color-matched to the iMac itself.
If you wanted that question answered, you now know how you’ll be charging your new Magic Mouse.
