As with all things, your usage is the thing that matters. I haven’t worn a watch longer than a day even when watch batteries lasted literal years and sleep tracking doesn’t interest me (I sleep like the dead - it’s great). So whether it’s 3, 5, 7 or more… anything after about a day is just a flex and isn’t particularly interesting to me.
