    Will doing this conserve battery by going with CDMA only? The closest city with 4g is New Orleans( I live in Louisiana) and if i do go to an area with 4g do i just turn CDMA/LTE back on?

    Central Oregon
    Where I live in Central Oregon there is no 4G yet at all. In fact I've never even used my maxx on 4G. Now if I were in and out of 4G areas I'd use the 4G toggle on/off feature for quick, easy access to 4G and back again. A widget you can put on your home screen.
    IMHO 4G would only be useful when web browsing anyway. So even if in an area of constant 4G one might want to conserve some battery by using the toggle.

    I'm pretty sure you won't see any savings by switching to CDMA/LTE. It might be an issue if you live in a marginal 4g area, where you would keep switching back and forth from 4g to 3g. And using 3g instead of 4g can save battery. But if there isn't a 4g network to connect to, you phone won't waste power trying to connect to it.

    Of course it's really not costing you anything setting it to CDMA only.

    I did a little test on this...I'm a truck driver so I get around to both 3G and 4G areas...and everywhere in between (this is what drains the battery).

    The battery will last a good bit longer if the phone is switched to CDMA only...if you have a good CDMA (3G or 1xrtt) signal...the difference on my phone was measured in hours, not minutes.

    I generally leave mine set to CDMA/LTE though, I'm always in the truck so I'm never far from a charger...and switching back and forth between 3G and 4G is a pretty big battery drain.

    In a nutshell...Yes, switching it to CDMA only will extend the battery by quite a lot if you are in an area where the phone switches back and forth.

    And even if you're in a solid signal area...it will still last longer in 3G.
