Recently, Apple pushed the new watchOS 8.5 system for Apple Watch users. This update optimizes the notification of atrial fibrillation recognition and fixes an email privacy vulnerability. However, according to feedback from user communities such as Reddit, some Apple Watch Series 7 users found that the charging speed of their watch dropped sharply after updating the version, and fast charging was the same as failure.
It is reported that some users said that after the updated version, their Apple Watch Series 7 was only charged 5% in 20 minutes, and even some users said that it was only charged 5% after an hour.
Under normal circumstances, because the Apple Watch Series 7 is equipped with fast charging, it only takes 45 minutes to charge from 0% to 80%, which is 33% higher than the previous generation.
At present, users have not yet analyzed the cause of the problem, and Apple officials have not responded to the problem or pushed a new patch to fix the problem.
