If you leave your device on 3G only, you'll see great battery life out of it. Sucks that they don't give us an option for 4G only.Here's what I got to say. I am at a location where 4GLTE is spotty, but there is a strong 3G presence. I catch my phone bouncing back and forth from 4G to 3G. What bothers me the most, is that the data service will completely cut out all together for several minutes at times. My OG DroidI did not exhibit this behavior.
However, when 4G is on...baby its on!
