So, with an AMOLED screen, colors are generated by illuminating individual LED's. Black is 'created' by NOT illuminating LEDs. Needless to say, dark screen = less power (unfortunately black is not zero, but its as close as we can get). As a result, some of the more serious battery power conservationists out there run black or very dark wallpapers to minimize power usage. I just thought I'd share a handful of my favorites. I didn't make them, I just like them!
It only took them a month or 2.... but Verizon finally started pushing the 4.0.4 update to its Galaxy Nexus users yesterday. The rollout seems to be going gradually, with some reports that Verizon plans to spread it out over 10 days.... which seems ridiculous yet on par with how they've handled everything about this phone.
