Can't get my Gear 2 watch to charge anymore.

I've read through a few of the previous threads about gear 2's problems charging and I still can't get mine to work.  For a long time it worked just fine, then every once in a while it wouldn't start charging so I would re-dock it till it did start to charge. Now, on two different chargers (wall and computer usbs), it won't take a charge 99% of the time. Recently I've been trying to charge it any chance I can to see if it takes anything and the charge dispaly just dosen't show up but each time I look at it the battery is lower. But if I leave it docked for over a day I will come back and it will have a full charge.
