That's why the first thing I do on my new phone is disable the Google app. It does absolutely nothing useful for me, but never sleeps, eats resources and shows you advertisements.

I also hate the mobile apps that designed to be always on, always listening or nagging. So, I have the policy: if the app is only useful occasionally and it is active but I didn't start it - I disable it. And I'll enable an app when I need it, not whenever it wants me to use it.
