[QUOTE="pskim586, post: 907851, member: 120932"] Hm.. I experienced the exact same thing also and mine is just 6 days old. Prior to calibration it showed it as having 5525 mAh but after calibration it decreased significantly to around 5300, but it didn't stop there, it kept dropping and went down to 5199 mAh all in about 2 days. I took my Macbook Pro 13" to the Apple store and they replaced the battery for me becaues they said 97% was within specs but mine was at 95%, but I don't think it's any better. I'll have to wait and see within the next day or two to see if I experience the same thing. And the thing is, it's not even that it's "showing less" or "showing actual" because of it possibly being "mis-calibrated", I actually got less operating time on the Macbook after calibrating, and even with the new replaced battery, I'm not getting the same usage time as I did when I first charged the Macbook out of box and used it.
