Photos that might show the back of the second generation iPad mini were released online. Looking at the photos you can see that the back is made of aluminum (like the current one) but its size has increased. The reason for the increase may be either because it will have a Retina screen or because the Cupertino company wants to put a larger battery.
The pictures are of dubious origin so no one can know if it is real or fake.
Stay tuned for more information that may be released.
