Query: Stopped working almost immediately

I had no problems uploading pictures to this device. However, the problem is is that it doesn't want to hold a charge. I plug it into the USB port for several hours and then when I try to turn it on again a day or two later it won't turn on and needs to be charged again. The product specifies that the charge should last for 4 hours.
