I just received my watch and the battery life is terrible ... It runs out of battery after more than a day without doing any activity. Then I notice the backlight is ON when the wrist HR sensor is ON (if the turn off the sensor, the backlight only on when the key or gesture trigger). Currently, I have the turn of the HR sensor all the time and the battery life seems ok. However, it is quite inconvenient to have to turn on HR whenever I start an activity. Just curious whether anyone experiences the same issue? Is it a firmware issue (I have done factory reset several time and it does not help)
