Proper calibration out of the box will bring it up close/closer to it's total capacity. Out of the box the 11" I had was 4387 of 4680. Two full cycles of calibration and it's now at 4668 of 4680.
I have an odd problem with my 11", the total battery capacity actually seems to drop after each calibration. I started at 99% of maximum capacity, have now calibrated twice, and am at 97% of max capacity.
For reference, I currently get 4,572 mAh with a design capacity of 4,680 mAh.
