watchOS 8.5 replaced the Apple Watch Series 7. But fast charging can be broken

While the Apple Watch Series 7 didn't come with long battery life, it did offer fast charging — at least, it was until last week. As 9to5Mac reports, some users are now complaining that the feature doesn't work after updating to watchOS 8.5.

Fast charging is exclusive to the Series 7. Along with this, Apple says that the battery of the watch can go from 0 to 80 percent in about 45 minutes. However, Series 7 owners on Reddit, Apple's support forums, and MacRumors' forums are saying that their watches are now charging at a snail's pace. Some Reddit users claimed that the watch would charge only 5 percent in 15-20 minutes. Meanwhile, a user on Apple's forum claimed that the watch charges only 5 percent in an hour. For context, Apple says the Apple Watch SE can reach 80 percent in 1.5 hours.

Initially, it appeared that this problem was affecting only those using Belkin's 3-in-1 BoostCharge Pro. However, some have claimed that the problem extends to Apple's own fast-charging puck as well. The Verge contacted Apple and Belkin for comment, but did not immediately receive a response.

That said, while 9to5Mac says it has been able to confirm the issue, The Verge wasn't able to replicate the problem using a 41mm Series 7 with a fast-charging puck and 20W Apple charging brick.

Battery life is one of the main "bottlenecks" of the Apple Watch. Since the first iteration of the Watch, Apple has stuck to its estimate of 18 hours on a single charge. (Practically, it might take you a bit longer, though you still have to charge daily.) Fast charging was meant to take the sting out of strategic planning when it comes to charging your watch. , especially for those who want to use it. For sleep tracking. ,

Convenient, fast charging on the Series 7 requires users to jump through a few hoops. The Series 7 ships with a compatible fast-charging puck, but you'll need to supply your own USB-C brick. That brick also has to meet Apple's specifications (which you can check out here). While older Apple Watch chargers will work with the Series 7, you won't get faster charging speeds. Also, if you're using a third-party charger, it probably doesn't support fast charging. Currently, there are only two third-party Apple Watch chargers that support the feature — and both are from Belkin.

Hopefully, a fix will come soon. In the meantime, you'll want to put in a little extra charging time.
