Have you tried OMEGA 9 ? It was the best battery life of ANY ANY ROM that I've ever used. In sure only because the rom is built natively for the s4 while my source based rom is based on open source project code.Let me know which one you try. Want to see what all the fuzz is about the tw people claim because I love this ROM and 4.3 run waaaay better than 4.2.2 tw.
