Once a week? I easily got a month of battery out of my Pebble (whatever the base model was). It was awesome, and I'm still bitter about the sellout to Fitbit. Now I have the Amazfit Bip which gives me around 35 days of battery between charges. I can't see myself buying one of these smart watches that requires a recharge every day or two, it's already annoying enough to recharge my phone and bluetooth headphones every day.
