I don't feel right if I don't charge my watch every day because it's an ingrained routine, and I don't like to charge it if it is above 40%, so the fact that it does not go for 48 or 72 hours is just fine with me. I don't know what life the OP is getting, but I've seen some people complain about not getting three days out of a battery, as if batteries don't deplete with use.
