This is a nice to have feature, but especially useful here:

The new charged notification is a useful feature for the ‌Apple Watch‌’s Sleep app, which lets users wear the ‌Apple Watch‌ at night for sleep tracking purposes.

The ‌Apple Watch‌ can’t be charged while it’s worn at night, of course, so after waking up, it will need to be placed on the charger if the battery is getting low.

Wake up, throw your Apple Watch on the charge, do your morning Loop posts (OK, maybe you do you), then, when you get the notification, grab your watch and go.
