One of the few new features in the Apple Watch Series 7 is fast charging support, resulting in 33% faster charging time compared to the Apple Watch Series 6. However, Apple says that fast charging requires a new USB-C cable (which now included in the box), but MagSafe Duo owners may not be able to take advantage of this feature.
According to Apple, the new Apple Watch Series 7 can go from 0 to 80% charging in about 45 minutes when using the new USB-C fast charging cable. The company also highlights on its website that 8 minutes of charging provides 8 hours of sleep monitoring, which is a huge improvement as the Apple Watch battery still lasts no more than a full day.
Here’s what Apple says on its website:
Charges in no time. The entire charging system for the Apple Watch Series 7 has been rethought to make you drive faster than ever. With an updated charging architecture and fast-charging USB-C cable, it takes approximately 45 minutes to go from 0 to 80% charging.
Fortunately for those planning to buy an Apple Watch Series 7, the new USB-C cable for fast charging is included in the box. As noted by min 9 to 5Mac colleague Zac Hall, the company also updated the Apple Watch SE box to include the new USB-C cable — although that model does not support fast charging. The Apple Watch Series 3 holds a standard USB-A cable.
MagSafe Duo compatibility
Future Apple Watch Series 7 owners should keep in mind that fast charging may not work with the MagSafe Duo. Also noted by Zac Hall, Apple’s website emphasizes that the new Apple Watch Magnetic Fast Charger for USB-C cable is required for fast charging, while MagSafe Duo charger compatibility is not mentioned.
It’s also important to note that Apple emphasizes that faster charging is only unlocked in Series 7 when using the “fast-charging USB-C cable” that comes with the new Apple Watch. Our understanding is that the Series 7 will not see these faster charging times when powered by Apple’s MagSafe Duo charger or other multi-charging stations. Actual testing when Series 7 is available will be required to display fixed numbers.
Another related detail is that Apple previously offered a 0.3m USB-C cable to the Apple Watch before the Series 7 announcement. However, the company says that the cable with fast charging support is a new 1-meter version, so it is unclear whether the previous USB-C cable supports this feature.
The new 1-meter Apple Watch Magnetic Fast Charger for USB-C cable is now sold separately at Apple for $ 29. And like the Apple Watch Series 6, none of the Apple Watch models currently sold come with the power adapter.
