I bought a new Mac, a little over a month ago. It has exactly 15 battery cycles now (after my use, of course). So, definitely, a new battery.

But, my problem is that I can see, through CoconutBattery and iStats that it can only retain about 8100mAh. They state my battery is with a health of 92~93% (supposedly, this battery is rated around 8700mAh when new). I confirmed on Apple stats that it retains 8100mAh, but Apple tells me nothing about the total expected capacity.

So, my question is: is there a problem with my battery? Or this is just a normal manufacturing variation?Is there a problem with my battery, or is this just a normal manufacturing variation?

They all state the condition is normal. But I find it weird that it won't retain 100% or even close to that, like 97, 98, 99%.

I can only imagine in a year, this dropping to below 90, like around 80%. I had other Macs that retained that over the period of like 3 years or more.
