New Bootloader with Old Firmware

[artsy]

I updated my firmware and bootloader, but decided to revert back to the old firmware.  Now when I disconnect my portable from the USB cable the battery level drops from 100% to 95%.  I didn't have this problem with the old firmware and bootloader.  Is this problem caused by the new bootloader?  Are old bootloaders available somewhere?

Which player are you talking about exactly?
Possibly the "old" and "new" firmwares have different battery calibration curves to determine the state-of-charge from the battery voltage, or perhaps your battery is starting to wear out a little.
