Which watch do you have? "Vivo" doesn't say much since there are many different Vivos.
If nothing makes a difference then do a factory reset.

When I had the Pulse Ox set to auto and the data recording set to 'every second' it did drain the watch quickly. Also having the weather turned on by location of the phone while not having the phone close seems to tax the battery. Having the face 'always on' drains the battery. Doing many exercise / activity recordings or long activities will drain the battery. Features that take all day recordings like the Respiration feature will drain the battery faster but I use this one and the all day Pulse Ox and only charge every other day.
