Charging your laptop constantly will kill the battery. We’ve heard the advise about letting your battery run down before charging it again, but this really only applies to nickel-cadmium batteries, the sort of rechargeable battery we use to save money and the environment, replacing so-called ‘long-life’ batteries. A modern laptops is powered lithium-ion or lithium-polymer battery which actually benefits from being continually charged. And you can shortened its life by continually draining it. What is good for your laptop is good for your mobile phone too.
