I am not sure if alternative launchers such as Go Launcher and Regina 3D Launcher require extra battery power. I install these two days ago and since then my battery has had some strange drain. Struggle to get through the day now. Have Go Launcher running now with a theme. Surely this can't be the case that it is taking extra power? Battery stats currently have my usage at Display 42%, Cell Standby 42% and Android OS 8%. Any ideas why the Cell standby so high? I have not installed any other apps nor have I changed any settings other than the launcher.
