The report states that Apple has been testing the feature around its headquarters in Cupertino, California. While the company has been releasing a new Apple Watch every year since 2016, it looks like the feature will only be added in the Apple Watch of 2020. This is assuming the current tests are successful, of course.
Apple’s smartwatch already comes with a respectable number of health-monitoring features. The most recent iteration saw the implementation of an electrocardiogram (ECG/EKG) reader and is able to tell if the wearer is having irregular heart rates. The addition of a sleep tracker will finally make the Apple Watch complete as a fitness tracker and health monitor. All that said, Apple needs to first improve the battery life of its Watch. While most smart wearables with sleep tracking have battery lives measured in days, the Apple Watch needs to be charged every night. This makes the sleep monitoring feature moot if it can’t be worn overnight without needing to be charged first. (Source: Bloomberg)
