Hello guys, I ordered my custom brand new Macbook Air with 8 GB RAM and picked up from Apple Store 2 days ago.


However after fully running out of battery for first time, I recharged it to 100% and coconutBattery says the capacity is 97%. I did the calibration once with the very first cycle of battery.


I think 3% is considerably high for Macbook batteries, I heard they can still operate at 70%-80% capacity after 2-3 years.


Is this normal, or should I return the device immediately? I appreciate any thougts and experience on this.
