Nope. Sorry. Turn the screen off while charging. That does help charge it a little faster.
If you sleep more than 4 hours a night, you should get a full charge by the time you wake up.
Turn off autosync and background sync, too, and that should also help your phone charge a little faster.
EDIT: Also, charge with a wall charger instead of USB-charger connected to a computer. Wall chargers charge faster than USB-via-computer charging.
