Hi guys, I just wanted to share with you two changes that improved my Samsung s3 i9300 (Android 4.3 stock-rooted). My friend has the same phone and had the same results. I hope it's useful to someone:
1 - FastDormancy disabled.
My operator doesn't use it, so it causes over-warming and battery drain. If your operators use it you don't need to do this.

2 - ZRam disabled
This change fixes battery drain too and it reduces significantly the lag when you turn on the screen. I sometimes had until 30 seconds after I pressed the bottom. Now it's 2 secs. Not as fast as some phones of the same price but is way better than the 30 secs I had (It made me lose lots of calls).
Just changing this It changed 360 degrees my user-experience. Now my battery lasts twice the time and I don't have the problems I mentioned before.
