I can assume as English is not your first language that you probably do not read these forums so much. So I will make this simple. Battery patch is not supported by the KP development team. If you have an issue running KP49+battery patch you must raise it with the creator of battery patch in the battery patch thread.

Almost all people here have no problems with KP49. All people who do not have problems also do not use battery patch. The suggestion being, don't use battery patch until it's creator can solve the conflict with KP49.

To aid in the diagnosis of your battery issues, use top, powertop etc.
