This application is for the Samsung Galaxy Nexus LTE on Android 4.x but may work with other CDMA devices (especially US Cellular and Sprint Phones).
If your LTE phone is struggling to keep battery life this app is for you. All day battery life is usually much more important than the speed of LTE and most day to day phone tasks do not require speeds over 3G. This application will allow you to easily and conveniently switch between 3G and 4G LTE without having to drill through multiple settings menus. YOU WILL see better battery life if you use this app to turn LTE on only when you need it.
