Can you tell what you did?
I see much better battery life with cyanogenmod base rom
Kernel i change to badass. Noop i/o. I underclock to 1026 seems to play most games ok no lag. Also use greenify dont sync apps. Set app as to manually update them.
Also black dark apps helps in some roms turning the hardware key lights off helps. And if using cyanogen mod stop wakelock RILJ.
Altogether and you will see a difference in battery life iblove the dirty unicorns 4,4,2.
