That's weird because I get much better battery life on Wifi then on Mobile Data.
Wifi = Best battery life.
4G (HSPA) = Second best battery life.
LTE = Worst battery life. *even more so if you don't have a good signal*
------------------------------------------------------------------------------------
If I'm at home, I'm always on Wifi. I get the best battery life. I don't use Wifi calling often so I'm on Wifi and 4G (HSPA).
If I'm out I turn off Wifi and use 4G (HSPA) and I notice a difference in battery drain. A noticeable difference to say the least.
If I'm out or home and I decide to turn on LTE I always notice a huge battery drain. On LTE it's crazy battery drain. It's very spotty and I don't get more then 3 bars. When I do have a good signal on LTE it's great and my speeds are crazy fast. I still notice the battery drain but it's not as bad when I have a good LTE signal. But if I move a few feet the signal drops down to 4G. There are some areas that I can keep a ok signal but that's only within a block or two...
