What is the 80/20 rule for charging?

The 80/20 charging rule for lithium-ion batteries (phones, EVs, etc.) suggests charging to a maximum of 80% and avoiding discharge below 20% for daily use to significantly extend battery lifespan by reducing stress on the electrodes, as the highest stress occurs at full charge (last 20%) and deep discharge. While charging to 100% or letting it drop to 0% isn't inherently bad occasionally, consistently staying within the 20-80% "green zone" minimizes battery cycles and degradation, keeping it healthier longer, though modern software helps.
