With smart watches we still have problems, mainly to hold enough power. Yes, Pebble can last a week, but that's because it is running less resource intensive hardware, and even then 1 week is still laughable when comparing to old watches that require battery change once per 2 years. By being more conservative, you can achieve more with less resources.
