To you experts you I pose this question. My understanding is that trying these "battery resets" (sort of depleting the battery then topping it up) is useless for current Li-ion batteries for laptops, smartphones, etc.
So it's good to calibrate from time to time to get more accurate readings, not to extend the battery lifespan. I guess calibrating too often would shorten the lifespan.
I meant Li-Ion sorry, corrected.
