Well, hang on a dang minute!!
In the first screen grab, you've been talking on the phone for an hour and a half, and you've had the screen "on" for two hours -- correct? Well, that's some of the heaviest use I have ever seen in my entire life!! Heck yes, you should be burning through your battery with that.
Then, in your second screen grab, you've had your screen "on" for ALMOST THREE HOURS -- two hours and 43 minutes???????? What on Earth are you doing with your screen on for hours and hours and hours and hours all day long?? Once again, that should burn through your battery like there's no tomorrow.
Then, in your third screen grab, you haven't been on the phone at all, and your screen was "on" only 43 minutes. But, on the other hand, you still had the screen "on" almost all of the time -- the measurement was for only 46 minutes. Again, what are you doing with your screen "on" all the time???
All I can tell you is that having your screen "on" most of the time is going to eat tons of battery life. Talking on the phone for hours is going to eat tons of battery life. If you truly have been keeping your screen on "almost all of the time" like this, and if you truly have been talking on the phone as long as it showed that one time, then you are USING YOUR PHONE, and that's what will use up its battery life. As opposed to, say, just having it sit on your desk or wherever, with the screen off, and perhaps just checking for e-mail every now and then.
If you truly have been using your screen the lengths of time that your screen grabs have shown, YOU DON'T HAVE A BATTERY LIFE PROBLEM. Same goes for talking on the thing for a couple of hours. You are USING THE PHONE, which simply uses battery life. But, if you HAVE NOT been keeping the screen on for the kinds of hours shown in your screen grabs, then you would have a problem. In the end, NOTHING is going to give you appreciably better battery life, if you're going to keep your screen "on" for hours like that. The best you could do would be to find the phone with the largest battery available, whatever it might be.
For whatever it might be worth, that's sure how I see things. I'm happy with my S6's battery life, but I'm mostly worried about "battery drain overnight" and such stuff -- if it's burning through the battery when it's just sitting there doing virtually nothing. And I sure don't have any problem like that with my S6. But it sure looks like you are HEAVILY using your phone -- almost CONSTANTLY using it. And yes, that will burn through battery life. Again, if you're going to be constantly using a phone like that, then you don't want something like the S6 with a rather smallish battery -- you want to hunt down the biggest battery in the entire industry.
