I too started off charging it in our bedroom, on my nightstand. Once I started using it for sleep tracking and silent alarm, I started charging it earlier in the evening.. usually during the quiet part of the evening when we are reading or watching TV before bed. I moved the charger to the home office on the main floor. I also top off the charger early in the morning while I'm taking a shower and getting dressed. For that it would be more convenient to have the charger in the bedroom. Maybe I need two?
