I'm using suemax 2.2 pro kernel and getting around 5.3 hours of battery life with this rom. And for Google play service you can manage it's permission from settings > general > permission manager.Please could you also fix the Google Play Services wake lock issue? It's killing battery constantly. Other roms have corrected this.
