IHS iSuppli said that Apple managed to reduce the size of the iPad 2 in comparison to its predecessor by “trimming the dimensions of several key components, most notably the battery” – the depth of this component was cut by 59 percent. Other significant reductions were seen in the touch-screen overlay and the clearance. The iPad 2 is 8.8 millimetres thick, compared to 13.4 millimetres for the iPad 1.
