10 Hidden Features of Smartphones To Change Your Daily Life

6. Turn Your Phone into a Personal Sleep Tracker

You don’t need a smartwatch to track your sleep—your smartphone can do it. For iPhone users, the Bedtime feature (found in the Clock app) helps establish a sleep schedule and tracks your sleep quality based on phone activity. On Android, Google’s Digital Wellbeing and Sleep Mode monitors your nighttime habits, offering insights into screen usage before bed and sleep patterns. Many newer phones also have built-in snore detection, movement tracking, and ambient noise monitoring to provide deeper insights into your sleep quality—all without needing a separate device.
