Battery drain is usual in NRGz roms... They are built for speed...speed...speed, but with that, comes the sacrifice of your battery (suddenly, it got chilli in here..jejeje).
Lets just say... in rom terms; EnergyROMs are not "eco" friendly..
BUT THEY ARE THE BEST-FASTEST...
I love these roms. I am currently using 23544 CoOkie build. THIS ROM IS AWESOME!!!
Thanks NRGz. =D>
