This battery has a capacity of 3000mAh, which is an additional 900mAh over the stock battery, keeping your Samsung Galaxy S3 going for longer.
Replacement back cover houses the extended battery and protects against damage.
As this battery is bigger in capacity than the standard one, it also has to be bigger in size. To accommodate this, the battery comes with a specially built replacement back cover that houses the battery, while also offering additional protection to the back of your phone from scratches and scrapes. The battery is approximately 1.5mm thicker than the standard battery. As a result the camera will now sit flush with the phone.
