Cycle it down to 10% and try a full charge again...Mine goes to 100 and has had one full charge from 10%. If yours still won't show 100% maybe take it in. Apple have a battery policy, but as far as I know a brand new device should charge to 100. The battery FAQ
Mine did the same thing. I then took it down to 0 until auto shutdown and fully recharged all night. Now it's perfect. 100% and i feel a slower discharge rate to.

I took mine down to 0 then to 100. I'd suggest letting it charge overnight since it can take a while. I'm not sure how long mine took to charge because I was sleeping. As long as it shows 100 in the morning i am fine.
