Motorola RAZR V3

I've read that cell phone battery life can be extended by calibrating/conditioning the lithium ion battery. I'm familiar with the concept and procedure from computer laptops (charge fully, run all the way down till device shuts down, charge fully), but am wondering if it's, indeed, advisable to do with cell phones (and the RAZR V3 in particular). Does Motorola have an official position on this?
