Part 3/10:
Among the notable features of the Series 10 is its ability to provide sleep apnea notifications, detecting potential signs of this condition over a 30-day period. It's important to note that this feature is also available on older models like the Series 9 and Ultra 2 with a software update. The battery life remains rated at 18 hours but can extend to a day and a half with lighter use. Fast charging capabilities allow the watch to reach 80% battery in just 30 minutes, making it a highly polished choice primarily for iPhone users.
