How often do you track exercise with it? That watch looks like it doesn't actually run anything on it except a heart rate monitor and is just a passive bluetooth enabled notification display so that would definitely explain the difference in power usage.
Yes, for sure it does much less. It just has basic health monitoring, steps, heartbeat, sleep. I have the continuous heartbeat monitoring off, and turn it on for workouts 3-4 times a week. It will show messages, email, or other app notifications. For me that's most of what I want from a smartwatch, and I'm willing to trade the more advanced features for the battery life.
Chinese naming can be pretty interesting. Probably would pay for itself to hire some native English speaking naming consultants. I've got my Bip on a Niziruoup rubber strap..
