Good morning, I have an ipad mini purchased at Apple Store in May 2013. The battery is charged 100% daily and practically drains down all day to near empty. May I please have a recommendation about my options. Should I buy a new ipad mini or what about a battery replacement (and if so, what would Apple cost be)? I had the mini replaced once while it was under warranty because of a key that wouldn't work. Suggestions appreciated, please. Thank you.
