Well, your initial statement was that you have a freshly flashed device with only KP49 installed. Now it turns that you actually have a lot of stuff on it besides KP49. And because you are the first one to report battery life got worse by installing KP49, it is obvious that some software installed on your device is incompatible with KP49. Noone is saying that it is your fault, so take it easy. And there were several reports that some of those CPU/memory monitoring tools are causing troubles with KP49.
