Q: Why is my battery health decreasing so fast?

Hi Apple community,

I have bought my Macbook Pro retina last week and the battery is steadily decreasing in capacity.
When i first bought it, it had 6750 capacity. NOTE: when i bought the back it had already had 3 cycles. Now after using 2 cycles myself, it has dropped to 6200. Here is a picture.

Is my battery faulty? And if so, should i take it to Apple?

MacBook Pro (Retina, 13-inch, Late 2013), OS X Mavericks (10.9)

That's very odd. How are you charging it? Like are you using any intensive applications while charging?
