Mainly texting and some web browsing, nothing really as heavy usage, but regardless, 2-3X better than my iPhone 5, without a doubt.
I have noticed that I tend to get better battery life with LTE on over 3G though. Maybe its because my LTE signal is stronger than my 3G and is using less power to search for a stronger signal.
The numbers will vary for different people in different locations under different usage and at different times (even for those same people). Hard to make comparisons really, aside from perhaps some extremes.
