Here are my latest battery stats with the new radio, there is no doubt I'm getting better battery life after switching to this radio. I base a lot of my results on my awake screen time. Usually before I'd get 1 hour 15 minutes to 1 hour and 25 minutes on a full charge. This new radio I'm getting 2 hours of awake display time. I also see my phone signal is changing more on the new radio, I think this is where the savings is being seen at. Some how the 4g signal is being put asleep after the screen is turned off for a certain amount of time. I consider myself more towards a heavy user, I'm on my phone all day.
