Curious. Most people are having trouble charging their X50 from the USB port because of the limited current supplied under USB specs. Are you successfully charging your X50V from a USB port? There are several threads on this.

I hadn't been keeping up with the posts until today, but I guess I did a bit of an inadvertant experiment last night.
x50v was down to about 10% battery, plugged it into the sync charge usb cable and continued playing Warring States. Charged up to 100% over the next few hours (wasn't watching the clock that closely, and put it down for awhile now and again.)
End result - fully charged while running (for at least half of the time) thru a USB port on a laptop computer. I can tell you that it got a bit warm during the process, but not noticably hotter than using the AC adapter while in use.
I don't claim to be an electrical engineer, so you can regard this as anecdotal, but my USB port is still working, and the battery does seem to be fully charged (when I place it back on the cradle, light comes up green).
