Is it okay if my laptop is always plugged in so that my battery is charged 100%? Must I allow it to drain periodically by unplugging to increase battery life?

Answer:

It’s generally fine to keep your laptop plugged in, but it’s good to let the battery cycle occasionally perhaps once a month to maintain its health.

Modern laptops often have systems to prevent overcharging

but a full discharge isn’t necessary for newer lithium-ion batteries.
