i flashed this rom yesterday. and it really is fast... the fastest i have tried come to think of it. i cleared data and cache formatted system and boot before i flashed it. this was the first time that every one of my apps restored. i thought all was well last night and untill about 12:00 today. i used pandora from seven until then and my battery was down to 50%. with ss4.6 under the same usage w would only be down to 70%. right now i have only 20%. even though i like the performance of this rom more so than any other i am restoring back to ss4.6 simply because of battery life.
