Battery Question

Brand new 13'' Macbook owner here. New to the Mac world and was wondering about my battery... I have never seen it charge over 92% ... I let it on charge overnight and still doesn't charge over that, any ideas???

My next move would be to go back to apple and have them either fix or replace it.

Apple suggests that I let the battery completely die out then charge to full which I am currently doing.. hopefully this will help anyone else that is new to the Mac brand like me...
