just took a look at the battery report and my S4 is running at 14 1/2 hours off battery with just under 3 1/2 hrs on screen with 51% remaining! It isn't unusual for this phone to run 24 hrs plus when I need it with plenty in reserve. I usually plug it in at 17-18 hrs with 40% left in the tank! Now every once in a while I used to see the battery fall off unexpectedly, this seems to be the result of backround sincing and backround processes sucking down the battery! Once i went in and either froze these unwanted apps or limited the backround sincing on the apps I actually use, the battery life is in my opinion, excellent!
My setup: Google Now-on, K-9 Mail sincing 3 mail accounts, Wifi-on , GPS-on, Bluetooth-on, Smart Stay, Air View, Air gesture, all on, Flipboard, Accu Weather-manual sinc, Drop Box, set to sinc on wifi/on charger and Nova Launcher
S-voice, disabled, Wi-Fi Now, disabled
Display set to approx. 50%
Cheers
Just got the s4 and I conditioned it. Lasted me some good hours until recently. I have been struggling to get 13 hours of battery. I have spent around 3 hours on screen some with lte some with wifi but mostly wifi by a large margin. Yesterday I went out on a walk and I have cell wifi on switching between lte and 4g, playing spotify. My phone completely tanked in battery for a 45 minute trip with my phone just playing music while in my pocket. The phone overheated a crap ton like while on my walk I felt it through the case and pants. It usually overheats after use when I charge it though. What do I do? I feel like there is no point in the samsung s4 because you have to turn off all the cool features just to get battery!

I am highly inclined to agree. Another question to all who have an S4: Do you have Auto Brightness on? That feature is nice, but a battery killer. It frequently tests the ambient light and adjusts the screen brightness to accomodate.
Battery usage is highly subjective. I get great battery life from my iPhone 5. It lasts me 24 hours between charges. Having said that, Anandtech did standardized testing on the S4 and the iPhone 5 lasted longer in 2 out of 3 tests:
