To all having battery drain issues, why not revert to uckh7, root, cwm, your phone and then use a custom rom? I am running UnNamed v2.2.1 which is based off of uckk6 and I am pulling a lot better battery life compared to when I was running uckh7 *stock* rom. I plugged my phone around 2 hours ago and I had not had to charge it since I pulled if off the charger at 8:30 am yesterday even with talking on the phone for well over an hour and when I went to bed last night, still had 57% and woke up with 55% and started charging after it hit 23% battery life today!
HTH,
Charlie
