Why Do Smartphones Always Know When to Wake You Up?

Smartphones know when to wake you up because they learn from your habits. Imagine your phone is like a friend who knows the best time for you to get up, it checks how long you've been asleep and picks the perfect moment to ring, just like you would if you were trying to wake yourself up gently.

Examples

Your phone wakes you up after you've slept for about an hour and a half, like a parent who knows when to call you for breakfast.
It learns when you usually wake up and starts ringing earlier on school days, just like your brain would do if it were trying to help you get out of bed.
If you're lying awake in the middle of the night, your phone might stop vibrating after a few minutes so it doesn’t keep you from sleeping.
