The iPad mini with Retina display is far from a smaller version of the iPad Air, as it comes with a decent 24.3Whr, dual-cell battery which would be a whole lot better than its 16.3Whr unit that can be found in the original iPad mini. The A7 processor underneath the hood will also be similar to that found in the iPhone 5s. The final score stands at 2 out of 10, where 10 would mean that it is extremely easy to repair. According to iFixit, chances are you will not replace any of the parts on your own, although the LCD and glass have not been fused together since they are able to be replaced independently. As for the battery, it is not soldered to the logic board or other components, but do bear in mind that the screws are extremely tiny, since they are easily misplaced.
