I don't get it. You need to charge your phone anyway. You just make that part of the phone charging routine. I have a MagSafe triple charger next to my bed that I throw my phone, watch and AirPods on before I go to bed and everything's good for the next day. I also have a compact MagSafe triple charger for traveling that I keep in my go bag.

That is the ideal solution, but some people use it to track sleep, that require you to have it in your wrist while sleeping instead of charging.

For some time i used my older Serie 3 for sleep tracking while the serie 6 charged for the day, then the Serie 3 would charge during the day. That until they released the updated sleep tracker that was not available for the serie 3.

Now I personally charge mine while i am in the shower. But i have the battery run out on me some times.

I use my Series 4 for sleep tracking.

I normally have it in Theater Mode so that the display is off except when I explicitly touch it or press a button [1]. That saves a lot of power.

In the evening when I've finished dinner and sit down on the couch to do the NYT crossword puzzle, read a while, and maybe watch a little TV I put the watch on the charger which is next to the couch. It is usually in the 35-50% range when it goes onto the charger.

Sometime in the next hour or so I'll notice that it has finished charging and put it back on.

[1] There is a setting for that somewhere in the settings, but it is faster to just swipe up and tap the Theater Mode icon. That also turns on silent notifications, but the icon for that is right next to Theater Mode, so another tap on the same screen undoes that, leaving it just in Theater Mode.
