Also been having battery drainage issues. I'll turn my tab's screen off for the night with 25%+ battery left and its completely dead in the morning. It's happened multiple times over the past few weeks, but the rest of the ROM is so sick that I have been overlooking this minor issue
you have to have a rouge app going crazy somewhere in the background because battery life on this rom is just as good if not better then stock bro. Get CPU spy from the market and make sure your tabs going into sleep mode.
