Hello!
Can someone please tell me what is the default Full Charge Capacity (mAh) of MBPr 13" battery when it's new?
Recently I noticed that on my device it shows only 6069 mAh, though my device is barely a year old and has only 41 charge cycles (of 1000).
Why would battery degrade so quick?!

What makes you think it has deteriorated? It's condition is reported as normal. The battery is charging normally. What did you think the full charge capacity should be?
I expected approx 6600mAh - that's the charge capacity usually declared in reviews. I don't know exactly, though - that's why I'm asking about NORMAL capacity.
Furthermore, I recently faced some strange battery behavior - after heavy loads (Civilization 5) battery after some time shows more charge remaining than there was when I closed the lid.
For example I close the lid with 17% charge left and when I open the lid again I see 20% charge.
First, the amount of remaining charge is a dynamic figure that changes with the changes demands on the battery. Closing the lid means less demand, so the battery will last longer. Lid open means higher demand and less life of the battery.
The number cited in reviews is a nominal figure and can vary from battery to battery. You should fully charge your battery to make an comparisons. A battery's full charge capacity declines as the battery gets older and is used more. It will never be the same after the day it's take out of the box.

No. NOT the REMAINING charge. See the first message - I pasted the required argument.
Full Charge Capacity (mAh)
I have strong suspicion that battery lost quite a bit of it's full capacity. Judging from reviews it's expected to be about 6600mAh (not 6000). Can someone tell me what is the default "out-of-the-box" value of this parameter on MPBr 13" late 2013?
Furthermore - battery started to behave strange. After heavy loads it gains some charge after an idle perioud (withput any charge of course). For example I close the lid having 17% charge left and when I open 5-7 hour slater I get 20% charge left. Though no charging was performed during this period.
All-in-all, I warry battery performs strange
Then make a Genius Appointment and take it in for service.
I just asked if anyone knows what is out-of-the-box Full Charge Capacity. What would Genius tell me? "Everything is normal"?
