Well I was concerned about my battery lasting not as long as i first got my macbook. To be more precise at first I had around 3.45 to 4.15 hours and now i have one hour less. 2.45 to 3.15 hours. So i downloaded cocconutbattery to check it out. Cocconutbattery shows that I have only 77% of my battery left!! My macbook is 3 months old although cocconutbattery shows iti is 5 And I have 85 loadcycles. These 3 months ,almost every time I left the macbook to full discharge & then full charge it again. And also I never shut it down ,cause I prefer to put it in sleep mode. Is this normal? 77% after 3 months use? Should I call apple?
