Yes the batteries are small, but other brands last much longer than Apple watches. And really, setting your watch down on the wireless charger at night is no harder than plugging your phone in or taking your regular watch off and putting it on your nightstand
That's my bad then. For some reason I was getting my info mixed up. Anyways, yeah 30 days is a long time but companies always bullshit like that where they say "up to". My galaxy watch 3 is pretty good on battery life, like a day and a half of me just using it regularly for time and heart rate etc. The biggest problem I have is that if I want to sleep track with it I need to remember to put it on the charger when I sit down at my desk and most of the time I forget so it dies on me.
