Dual-Core Orion CPU From Samsung Announced

The pair of 1GHz ARM Cortex A9 cores will come for mobile devices in 2011 with 1080p playback and recording, dual triple screen support and five times the 3D graphics performance than the current processors, you know the ones that are now used in the Galaxy S and Tab. I understand that it is important to use a dual screen phone for 1080p playback while you are driving an additional external screen. But what about battery life?
