While all berries have their own personality because each has a different setup, jalaws themes have always been rock solid. His themes are tested on different os's with different combinations of apps. If your on a s1 that could be part of your problem. If s2 something is wrong.
I would say keep everything as is and try the stock theme for 10-12 hrs and see if there is still a leak.
