I might just be crazy but... When I plug my Captivate into either a powered usb hub OR directly to my computer it seems like its draining the battery... To make sure it wasn't the cable (which I got at MonoPrice) I took the supplied power wallwart and used that with the cable I got from MonoPrice and it charges fine. 100% charge... connected to hub/pc... 20 minutes later is down by 20%. Same USB cable but now using the wallwart... 30 minutes later goes from 6% to 29%. Is there an easy way to see what kind of power the USB connections are putting out? I have a little Radio Shack multimeter but I've only ever used it to to test conductivity, pin outs on "odd" cables and checking the charge on batteries. Thanks in advance!
