We need this app for certain apps to work  but it uses so many services for example 1 process and 12 services along with all other Google apps. I need to close the services before I can use my phone at a minimal speed and disable the rest of the Google apps to save my battery power they are always running. Google is not the only apps that over use phone resources but it is the main ones. I don't know much about programming but I think it can be more efficient if they eliminate some of info gathering and permissions.
