Default USB port drains the Blackberry battery

Please Login to Remove!

After I sync my 8330 Curve with my MAC desktop, I leave it plugged into the USB port overnight to charge. In the morning, the device is completely dead. Anyone know why the USB port is draining the battery rather than charging it?

Thanks for the help.

I'm not sure which port it is one port has less power actually running to it, therefore it is insufficient to charge your phone. why not just do the wall charge?

When OS X goes to sleep it no longer charges the device, but, mass storage mode is probably still on which drains it.
