So I decided to calibrate my battery last night, something Apple told me to do and something everyone recommended. And for the most part, on my old laptop, when I calibrated it, it got longer life. Now, CoconutBattery before the calibration said I had 94% on current battery capacity, but this morning (morning after the calibration) it said I had 90% Battery capacity. The calibrating made it worse. Did I mess up on something? Please help.
