While that is pretty awesome, and I've played with Android tweaks to get better battery life in the past, the software doesn't seem like the biggest consumer of power. These days I generally I see >80% of battery power being used by the screen, so no matter how well optimized the software/cpu/gpu is, actually using the device is going to kill the battery.

Added: With Timur's Kernel and some rtc/wakeup/governer tweaks I can get at least 2 weeks on my nexus7.
