Since the days of the Zilog Z80 CPU in the Gameboy, there's always been a CPU opcode made to put the CPU into "sleep", until the next batch of processing is required (usually the next vertical refresh cycle). This sleep mode significantly improves battery life.
My guess is that they've either found a way to make the CPU sleep quicker, or they've altered the firmware to be more efficient (and therefore go into sleep mode a lot earlier). More efficient context switching, perhaps?
