Not True.
My iPhone 5S last at least 2 hours longer than Samsung S5 on the same amount of usage time and activities. I suppose people who think their Samsung last longer never used it non stop on internet (which is likely what most iPhone users do because, honestly, and it's true, that iOS user experience is just better).
The only thing that Samsung has that iPhone won't do is replaceable battery.
