Apple has recently announced a smart battery case, which is basically a power jacket that we have seen the likes of Mophie make in the past. The case basically doubles up as a silicon case and a battery juicer. However, the case has come in for a severe criticism thanks to a rather ugly design, very uncharacteristic of Apple.
