Ok speedy story. Love the nexus but hate the battery. I want to root and get the most out of my battery. I'm nervous about flashing roms bc when I did it on my droid 2 it bricked every time I attempted a Rom. So I'd like to know what the best roms are for battery life and how to properly flash them. Nubcake question I know but I'm not a tech genius so I'd greatly appreciate some input. Thanks.
