The detailed map of sports health App sleep shows more than 3 hours of scientific sleep data. Sleep data less than 3 hours will not be counted in the sleep detail map, but will be counted in the sporadic naps in the details list, that is, "Night sleep duration+sporadic naps = total sleep duration displayed by the watch" in the App sleep details.
If the watch shows more sleep time than the sports health App, please check whether there are sporadic naps first. If the total night sleep time shown in the details of sporadic naps+sleep = sleep time shown by the watch, it is normal.
