*When the user recharges the battery to a lower percentage frequently ''(only charging to 100% when necessary)'', the battery is aged less, which ultimately result in better battery health and longer runtime should the user need 100% capacity, compared to always fully charging.

*The manufacturer blocked part of the available capacity ''after'' a certain amount of charging cycles. Meaning that after the user has degraded a certain amount of the battery, the manufacturer artificially limits its capabilities by further removing a second portion of the battery.
