Android 4.3 update draining battery (Galaxy S4)

Hi Samsung
Your latest approved software release for Android Jelly Bean (4.3) is a shocker. It was pulled completely in other markets for further testing. Since updating my device the battery barely lasts a day, this on device where I used to get no less than 36hours of moderate use out of my phone.
Considering the phone is 6months old I really think you ought to take steps to rapidly resolve the issue. Either rollback the firmware or release a fix.
Please let me know what your intended course of action is.
Thanks
