I am trying to get it resolved at the store level since it is still under warranty.
I just had this problem and posted a thread about it, and it sounds like the OP may have the same issue. Battery completely drained from 100% to 0% overnight with the phone completely shut off. I suppose this does seem like something that warrants a call to Verizon for a replacement.
