I'm new to macbooks and i have a question 2 questions about batteries 1.) So when i take the macbook out of the box, i fully charge it and then do i callibrate it (as in fully discharge it) or should i wait after a month? 2.) To extend battery life (as in using 2-3 cycles per week), should i use my laptop running the battery and charge it when it is low like 30-50% or is it better to use it till it gets to 70% and then charge it? Thanks for your help, much appreciated!
