I sometimes hook my Maxx up to my computer to charge it at work. Well I've noticed that when I let it charge up to 100%, then unhook it. The battery takes a lot longer to come off 100%. When I charge it using the wall charger, as soon as it reaches 100% I unhook it. Right after the plug is unhooked it drops to 99%. Why is that? Not that I'm worried, but just thought it was odd it does this.
