So I got my first Apple laptop, a Retina MacBook Pro. Since macbook pro retina's battery are no longer easily switchable I'm concerned about it's life and would like to maximize it. I have few questions below.
How long it should be kept in A/C power? Is it okay to keep the laptop connected to A/C power more than 24 hours? Will it not be good for the battery if I keep it in A/C power more than 24 hours?
Is it okay to charge the laptop when the battery reach 75% or should I wait till it goes to 50% or 10%? What's is optimal %?
What's the best charging practices should I follow?
