As reported here many times, the USB charging feature is not the best.

First, the USB port will not charge the reader if the PC goes into sleep mode.
Does the red light on top of the reader stay on during the whole USB charging period? If it goes out, that means the unit is not charging, and if still connected to the PC will actually discharge the battery.

Second, USB ports typically only put out 5.0 volts, so it will charge slower than the Sony wall chargers which are spec'd at 5.2 volts.

I strongly recommend you get a wall charger. You don't have to spend $30 for the official Sony charger. Any PSP compatible charger will work. You can find one locally, or on line for as little as $2. I use an old Dell Axim charger which is spec'd at 5.4 volts.

The drop in indicated charge is not unexpected. The reader does use more power when reading and sorting the library after transfer activity, but it should be negligible, certainly not have been two bars. I would expect the brief charge while connected to the USB would offset the power consumed by the internal library activity.

The battery charge indicator on the PRS-600 is reported to be less than reliable and may improve through a couple of charge discharge cycles.

I hope this helps.
