I have had my MacBook Pro (13 inch 2011 i5) for about 3-4 months and according to the widget, istat nano, my batterys health is at 92%. I have calibrated my battery once when I first got the laptop and 2 times other than that. I dont often leave it on the charge too long after it is charged and I always run it to at least 10-15% before i charge it. Should I Be Worried???
fully charge the battery, and then overcharge for another 2 hours.
let the battery discharge, and then allow to sleep for 5 hours after.
then recharge and allow it to fully charge.
If you use your laptop a lot, repeat this process monthly.
