the short answer is... do whatever you like, don't think too much will maximum battery life.
the long answer is... Don't over charging, and don't over draining. Use it like how you will use your cell phone.
just think how people use their cell phone. (i guess no one will charge it after just few phone calls, neither do people trying to squeeze out the last drop.) It is usually the best way to use battery. (a lot of phone battery can go more than 2 years with at least 500 charge/discharge circle)
