Should I leave my ASUS battery plugged in or not?

According to a www.howtogeek.com, they said there is no accurate answer available currently,leaving the battery at 100% capacity will decrease its lifespan, but running it through repeated discharge and recharge cycles will also decrease its lifespan. Basically, whatever you do, your battery will wear down and lose capacity. That’s just how batteries work. The real question is what makes it die more slowly.
