[Star Wars] How long will a light saber battery last from full if lit but not touching anything? How does use affect its life?

Theoretically? A lightsaber can last a thousand years without recharging, assuming no draining beyond general deterioration of the power cell's ability to hold a charge.

Usage shrinks that. Depending on how much a lightsaber is used, a Jedi might need to charge it only a handful of times in their life.

Maintenance, on the other hand, requires more regular care, again, depending on usage.
