Does anybody know for sure how the CDMA/LTE and CDMA only settings work? Let's say I am in an area where I know that I don't get 4G. Is the radio constantly searching for an LTE signal? I believe Sprint has 3G and 4GLTE on the same towers now with the network vision upgrades, so maybe there's no advantage to disable. I know I'm probably the person to answer this question since I can actually get LTE most of the time in my area, but does anyone leave it on CDMA/LTE and get the same battery life as CDMA only?
