You also have to take into consideration the ROM and the physical battery itself, and their respective capacities and efficiency. 3G, 4G, and 4GLTE, have notoriously been a battery-draining process for all devices since their inception, if I'm not mistaken. It simply requires more power to use, and therefore battery juice drains quicker when on the network as opposed to the easier alternative, WiFi. For example, I only use 3G when using Maps Navigation, because there's no other reason I personally should be using it. WiFi for everything else, and my device keeps it's juice for a long period of time.
Also, if it's of major concern, be sure to be using JuiceDefender.
That being said, my software version is VM696ZV4, and hardware revision is 1.1.
