Depending on what you want the watch to be able to do, there are much better options. The Garmin Fenix can last up to two weeks on a charge - I usually charge mine once a week, and with 5 workouts where I have chest band in use it's usually down to about 47% when I connect the charger. I mainly use it for the fitness tracking, but I have notifications enabled for text messages and other chat apps and the calendar.
