I got a macbook pro (first time mac owner) a few weeks ago. After calibrating the battery and uploading coconut battery and battery health monitor, both said that my macbook's current battery capacity was 97%. I contacted mac support to see if this was normal. The lady I talked to recommended that i should return it before Best Buys return policy ran out just to be on the safe side. I followed her advice and got a new macbook pro several days ago. I just finished calibrating the battery and this time it says my battery capacity is at 96% of its original capacity. Im starting to wonder if this is normal, that possibly mac just makes crappy computers that start out bad. Should I return it and go back to PC? Is this normal and I shouldn't worry about it? Should I return it for another mac because I just happened to have bad luck twice? I have read a few threads on here about battery health and several people have posted their health percent being at 100% even after months and hundreds of cycles, and sometimes years. This is the exact statistics from the Battery Health Monitor App. Original Capacity: 100% (5,770 mAh). Current capacity: 96% (5,566mAh). Current charge: 100% (5,560mAh). Charge Cycles 0% (1).
