I haven't tested many other phones as extensively, but today I happened to be working with a colleague who has an S5. I asked if I could check his stats because I was just approaching the 50% mark, and I was curious. He obliged, and to my surprise he was at 58%. My screen time was at 2.16 hours and his was 2.09. I would say that's pretty good life for the S5. Again, I don't know how far that 58% will get him, but I'd say that's pretty good battery life. What we were doing with our screen time is a different story. I was mostly on email, and I think he was mostly texting. I also had 1 hour of phone calls, while he had only about 15 min., which is obviously a significant difference.
Separately, I'm at 28% now and it's only 5pm. My Maxx never once got this low until around 8pm. I expect to get more out of this 28% than I would from 28% left on the Maxx, but I do expect I'll need to charge before the night is up.
