It's not that it's bad or that it's not working. The better signal you get the better your battery will be. The lower your signal strength is, the more your phone will strain to reach the towers and the more energy it needs to put out on the antennas to do so. Think of it as talking VS yelling; one is bound to get your vocal chords hurting way sooner than the other.
VoLTE means Voice over LTE, which is basically making calls over your 4G mobile data connection. Sort of like Skype but for your carrier. If done right, it has better quality than a 'regular' phone voice channel.
The biggest drain on your phone will be the screen, and you mentioned you're getting nearly 5 hours of Screen-on Time...that doesn't sound too bad to me, but if you really want to test it out, I suggest playing a video in a loop with SYNC off on your phone. You should probably be using about 10% battery per hour of video played on mid-brightness (again, that's an estimate, but an usually accurate one). If that holds true, then there's nothing wrong with your phone (and a single 2-hour movie would probably give you a good idea if the phone is using that much power or not).
Also, the best benchmark is your own: compare your phone life in previous ones to this. If it's similar at least, then you know that's just how you use YOUR phones. With your apps and your services and your area and your usage patterns.
