I've had my macbook for a couple months now (since the beginning of september?) and I've totally loved it. I'm the type of person who likes to nearly drain her battery completely, then recharge it to the max. My laptop is now at 99 cycles, and today i just saw the battery health go from 100% (4100 mAh) to 68% (3463 mAh). Previously, it had only gone down once, to 92%, but it went back up after another cycle. Should i be worrying right now?
