My VX6000 was on the last battery bar all day and I came home to pull off some pictures via the USB cable. I left it hooked up to the computer after I was done and went to my car and eventually found myself cleaning it out again. I came back after about 15 minutes and remembered the phone was still attached and proceeded to unplug it. THE CHARGE WAS FULL. I assume it is the USB power that does this, but it is only phenomenal because the phone charges in < 1/10 of the time, and I usually turn my phone off while charging. It is also much more convenient than the dock because when you have a leather case AND YOU LOST THE STUPID RUBBER NOT-ATTACHED THING THAT I THOUGHT I TOOK SPECIFIC PRECAUTIONS TO AVOID. Thinking back, this has happened before. Because I remember once I plugged it into the computer so I could add wallpapers before I went to charge it, but after I was done, I no longer had to. Mostly posted this just so anyone who didn't know does, and to see if just maybe it's an incorrect battery reading or something.
