I am very suspicious of high battery temps being the power drain culprit. Switching to NEAK had no observable effect, battery temp is hovering at around 40C, CPU temp feels much hotter (Elixir shows no CPU temp sensor?). I'm not sure what is going on with this ROM, whether it is the DPI changes or something else, but I don't want to risk damaging my phone with extended use. Going to try a few more things to see if I can find the battery/temp culprit before flashing back to AOKP.
For now I would advise watching your battery temps closely, it shouldn't get over 45-50C. Any higher and you risk permanent damage and high drain.
Again, thanks to OP for his work (and to all the others who built/contributed), I love this but don't want to burn out my phone
