Behind this screen, quite literally, is a revised display technology. Its believed to be a form of the Super High Aperture (SHA) process that allows incredibly tight packing of the thin-film transistors that comprise a display matrix. Apple as ever is tight-lipped about the minutiae of internal technologies, but we believe the first raft of new iPads are taking Samsung-made screens, with LG and Sharp mooted to contribute as production is ramped up.

The irony of Apples Korean arch-enemy supplying Cupertino with the very component that will push the iPad to a new level beyond the Android copycats is difficult to miss.

Squeezing four times as many pixels into the same 9.7in display gives a density of 264ppi. Thats lower than the iPhones 326ppi, but when viewed on a new iPad at a typical reading distance (Apple quotes 15in, which we confirmed is our comfort zone) the Retina effect is restored. Mind you, weve peered closer, much closer, and still cant see any individual pixels. Viewing most content on-screen, its like looking at a glossy magazine, not a computer screen.

To achieve this effect has taken bleeding-edge screen tech, more LED backlighting, and bigger batteries to drive it all.

Which is why the battery has been expanded by 70%, from 25Wh to 42.5Wh, to maintain Apples class-leading battery life. The company quotes 10 hour lifespan again. For the iPad 2, wed suggest that figure was slightly conservative, but maybe one thats closer to the case for the power-hungrier third-gen iPad.

Battery testing mobile devices remains an inexact science with too many variables to replicate a ‘typical usage pattern. In three days of testing, we had to charge the unit twice, where an iPad 2 may have lasted on a single charge. But our usage of the new iPad was perhaps far from average – in essence caning the device with near-constant use.
