My macbook pro 13" 2012 is 6 days old and is on 6 cycles because i have been charging the battery full every day and then discharging it daily. Is it better to do what i am doing right now or say charge to 100% then use until it is at say 45% and then charge back to about 80% etc. and then do a calibration once a month. which method will allow my battery to last longer for the next couple of years?
