my macbook battery isnt doing well at all. dying super quick but health is showing as "normal" yet the health varies between 70%-83% each time i charge it. it needs to remain under 80% for apple to replace it. right now as i type this its 80.3% under battery health using 2 different programs to check the health. a genius bar rep said its border line needing replacing but they cant do it until it actually drops below 80%, so i guess my question is how to rapidly degrade the battery life?

Cycling the battery at its upper or lower temperature limits will mature the battery rapidly

Run on battery to 4% then charge to xx%. Then discharge to 4% again and again.
p.s. weird thread indeed.
