watchOS 8.5 may have broken fast charging on the Apple Watch Series 7

The Apple Watch Series 7 didn’t have a longer battery life, but it did have quicker charging until last week. According to 9to5Mac, some users say the function no longer works after upgrading to watchOS 8.5.

Only the Series 7 has fast charging. Apple claims it can charge the Watch’s battery from 0 to 80% in 45 minutes. Owners of the Series 7 on Reddit, Apple’s support forums, and MacRumors claim their watches are now charging slowly. Some Reddit users said the Watch barely charged 5% in 15–20 minutes. A forum member said the Watch barely charged 5% in an hour. Apple claims that Apple Watch SE can reach 80% in 1.5 hours.

Initially, the problem seemed to be limited to Belkin’s 3-in-1 BoostCharge Pro users. Apple’s own fast-charging puck may also be affected, some say. Apple and Belkin did not respond to requests for comment from The Verge. While 9to5Mac claims to have confirmed the issue, The Verge was unable to reproduce it using a 41mm Series 7 and a 20W Apple charging brick.

The Apple Watch’s battery life is still a source of contention. Apple has long said that the Watch will have an 18-hour battery life on a single charge. (In reality, it may take longer, but you must continue to charge your phone every day). In order to make it simpler to schedule when to charge your Watch, fast charging was introduced. This is especially true if you use it to track your sleep.

The fast charging feature on the Series 7 is convenient, although it requires some work. The Series 7 does not, however, come with a USB-C charging cable. And that brick must also meet Apple’s requirements (which you can see here). Even the prior Apple Watch chargers will continue to work, charging rates may be somewhat slower. In addition, a third-party charger may not be capable of providing quick charging. At the moment, only two third-party Apple Watch chargers are compatible with the feature, both from Apple.
