[Star Wars] How often do lightsabers need to be recharged?

How often do lightsabers need to be recharged under normal use like deflecting blaster bolts,cutting droids apart and cutting through thin materials like a door/wall/grate?

Well, that's sort of the thing.  Deflecting blaster bolts, cutting droids, and slicing open doors is decidedly not normal use for a lightsaber.  Normal use is to hang on the belt and stay there.  It's a weapon of last resort.  

That said, an activated lightsaber recycles the vast majority of the power it emits if the beam isn't cutting anything.  So you could deflect blaster bolts more or less indefinitely.  Cutting does deplete power, but the power cells are advanced enough that you're looking at many many hours of active cut time before you need a recharge.
