tdgeek: After that, charge whenever. Battery life is x number of full charge cycles. It makes no difference if you always charge at 25% or 50% or 75%, etc
I have always wondered and now it seems there is a definite answer?
Can you explain how the battery knows how many full cycles if you always charge at near full cycle (say always charge at 75% will it last four times the number of charges if made at 0%?)
