Everyone seems to be pulling you different directions but I have a vzw lte S4 and about a week ago I bought my wife her iphone5 (she went from a 4S).
I too dont use any of the gimmick features and have them all disabled.
The S4 is on par with the iphone, and most nights we come home and my battery has 5-15% more than hers does...rarely does hers have more.
It will last a good 9 hours of nerd usage, 28 hours of medium usage, 30+ of light usage...AND...you can just buy a 2600mah anker battery on amazon for 12 bucks and keep it in your car or pocket to double that.
I got 99 problems but a B....battery aint one ;-)
