I usually just let mine toggle to whatever signal it is picking up .I am in a 4g area 90% of the time.I am usually on WiFi's when in those few spots of 3g only connections,unless I am driving or riding in a car.I have no complaints about my battery life or battery drain.
I have never used the phone info app.When I am at work , which is more times then not a 3g area it shows in the Mobile network type eHRPD:13.It evens shows that when connect to Wifi's in a 3 g area.
When I am in a 4g area it shows in Mobile network type LTE13 when either its on Wifi's or not.
