I guess. It seems pretty easy to me. I have the charger on my bedside table. I slip watch on there as I go to brush my teeth, etc, I read a book or watch TV for an hour and slip it on and go to bed. In the morning, I turn off the alarm and connect it to the charger. I just put my watch on last before leaving the house. It’s like 15 seconds of “work” and we already do routines in the morning and evening. If the battery lasted three days, I guess that would be cool but I’d have to remember every 3 days to charge it. Doesn’t seem that different honestly.
