I'm a Fossil Gen 5 running Wear OS owner and my wife is a FitBit Versa 1 owner. My Gen 5 for sure is smartwatch as it's main priority so it's definitely more feature full in terms of interactions with notifications. My wife loves how I can reply with either voice to text, drawing or selecting an emoji, or swiping to type a message on a little keyboard. However, the battery life is definitely a daily charge especially if you sleep track. I top it off in the morning and before going to sleep. Her Versa 1 is much more limited in smartwatch functions but does have a better minimum 4-5+ day battery.I bought the 4xl for a friend and setting it up for him. He also wants a watch that is fully compatible and has great battery.
I understand phones but know nothing about watches. Please help.
