How to remove OGBatteryMod topic

Well I have a question and it's, does anyone know how to remove the OGBatteryMod? What should I do? I already deleted OGBatteryMod.apk from system/app but then the battery icon dissapears from the statusbar. I read also that the app installs something on systemui.apk. I don't know how to decompile it and maybe someone could help me. I can upload my systemui.apk.
P.S.: I am on S-T-E S5 ROM.

Thanks for helping:)
