I agree it's a bit counter productive to buy a phone that offers a bunch of great features, only to have to have them off in order for the thing not to die.
But I must admit, toggling the switches on and off between use hasn't proven to be a great hassle for me. When I want to do extended web browsing or send emails with big pictures, I flip 4g on. When I'm sitting idly at the desk or sleeping at night, 4g and the rest is off. When I'm in need of navigation, GPS is on; it's off otherwise.
It doesn't seem like a huge compromise to me. But then on all my previous phones I've never left bluetooth, wifi, etc. "on" at all times.
