I remove all Samsung services. I don't use them anyways. Also lookup Greenify, noce little app helps on the battery, a lot! My setup is better battery stats to monitor any wakelocks, greenify to hibernaye apps that keep running in the background and now I'm testing Snapdragon Battery Guru, which is like a Juice Defender kind of thing. But designed for Snapdragon devices, so they say.
