Battery life with bluetouth enabled, notification mail and sms: more than 24h. On the other hand, it is also necessary to deactivate the motion detection for the activation of the time. Wifi and gps consume a lot. The wifi is a privilege when you are on the charger dock and wish to do an update. The motion sensor is very battery-consuming. I have not tested with a SIM yet …
I use my smartwash for watch (lol) and notification.
Sorry for my english. I’m french.
