Nothing like that. If I leave wifi on the battery will be dead overnight. There was no 'slight facetiousness' anywhere. I cannot rely on it having any battery life if I don't leave it charging or switch it off and as a result I don't carry it around like I did with the 770. its also is somewhat more fragile without the lid. As you said I guess I need to 'figure out what it is' that is wrong, somehow, however I can do that. Although I don't see how having wifi on when I am not using it really helps me.
