Sleep Tracking
One of the primary downsides about the Apple Watch as a health and fitness tracker has been the lack of sleep tracking. That’s a feature present in many mainstream competitors, including devices that are way cheaper and less feature-dense. But Apple is likely hard at work making native sleep tracking on the Apple Watch a reality.
The company has been working on proprietary sleep tracking tech for a couple of years and has made strategic acquisitions in that area. Native sleep tracking would require better battery life, however, since the Apple Watch only lasts about a day or a day and a half on a charge. But if a bigger battery and better energy efficiency are on the table, sleep tracking may be a more likely possibility.
