Yea, back in the day, when first phones and laptops were coming out, the tech was different, and was better to fully discharge/charge the battery. Nowadays it's the opposite, but the mith still survives

An easy analogy for batteries nowadays is to see them as an elastic completely relaxed at 50%. At 0% or 100% the elastic would be fully stretched. You want to avoid that to maximize its life
