Our Mini 2 has a bad battery that will no longer take a charge. It gives the red symbol no matter which charger we try and the port is clean. I was wondering what Mini version the Apple Stores are usually giving when you turn one in for a battery replacement. I am guessing a 2 at a minimum or any newer retina display model if they do not have a 2. I do not expect them to have many or any Mini 2 models.
