sorry thats complete bull****. You do not drain a lithium ion battery they have no memory effect and doing that will damage the battery. Best way is to do what you normally do. Go to bed leave it on charger wake up take it off use it like you do come home when it gets bellow 10% the nput it on the charger and dont take it off again till it either is ufll or you wake up. Keep it as full as possible= less damage to the internal compents= more battery charge you hold.
