My Alienware 13 R3 is only about 6 months old (I bought it in November 2017). However, after only 6 months, the battery has reached 30% wear level. It isn't even a year old, and the battery has already lost more than 1/4 of its capacity. I've tried recalibrating it, which only increases the wear level even further. 

What options do I have? Does Alienware replace batteries under warranty? Thanks in advance.
