The battery life on this watch is horrible. With a reduced screen brightness, a dark watchface with 3 complications and very light use, I get less than 24 hours of use. Increased battery size, and more efficient chip add up to zero improvement.
as with any new device, it usually takes a few days to learn your usage patterns and adapt. if you're still having issues after a week, maybe consider a reset. in the meantime, clear the cache partition from the recovery menu and see if that helps.
