I’m not watching the battery like that but my general advice is to enjoy life and enjoy whichever face your heart wants.Question for you: did you notice if the full screen colors in these new faces (white for the background plus multicolor for the actual face) affect the battery draining (compared to the standard black background in Meridiana, for example)?
How long is the face in active mode, really, right?
In the worst case scenario—older battery, 40mm, cellular, workout—maybe. But even then if you are in a workout the face isn’t showing at all.
That said battery seems very normal. I wear my old 40mm watches (the two on beta as well) for the same few hour chunk of time at home and they’re never below 40 on beta when I go to charge them for the next day and then turn them off (and am actively checking their %)
