A little advice:
which rom do you recommend to be complete but with better battery life?
Go for Cyanogenmod 6.5.7 stable.. Along with fserves goldenleaf kernel..!!
Perfect combination for a superb battery performance...!!
BTW a superb new ROM has been launched called PHOENIX ROM by a great developer Andy.. do check it out.. maybe that proves to be a great ROM with regards to the battery backup.. Still if you are in doubts.. go for the CM and goldenleaf kernel combo..
Found this website while googling for O1 Custom kernels. Pretty handy! - http://knowmydroid.com/kernel/lg-optimus-one-custom-kernels
