Does the job
This case is almost perfect. Fits the phone like a glove, adds extra weight and makes the phone feel a look sturdier. The battery works very well and once plugged in automatically charges the cases battery, if the case is switched off it will charge the phone instead (I have experienced a few times where if you turn the case off it will still continue to charge the case and not the phone while plugged into the mains) You get approx 75% of power from the case to the phone. A great extension to the phones battery life. My only gripe with the case is that it does not go perfectly with the Genuine Samsung car dock as the micro usb slot is located on the bottom right hand side and not in the centre. The car dock is designed specifically for the micro usb slot to be in the centre. It still fits snuggly but at a slight angle. Great case, I fully recommend it to any Galaxy S3 user. There are a lot of cases available and this is the best I've tried.
