In simple words samsung is cheating with indian consumers.the are providing us device which has octa core to convence large number costumers.in reality snapdragon is far more better then exynos, and which also means no 4g.sorry to say we fools are also getting convenced by octa core, air view, air gesture, eyes scrolling, IR blaster.
But in reality tthis all features are useless.samsung might have invest their money to improve their costume UI’touch wiz’, gaming performance which is also not up to the mark, games like gangster vagas, nova 3 does not run smoothly, camera’s night performance is also average.rather then their unique features.itsa battery life is also not good.maximum screen on time.
internet via 3g- 3 - 3.5 hrs
internet via wifi- 4 - 4.5 hrs
video(online) - 3hrs
video(offline) - 6 - 7 hrs
music - 9 hrs
intensive gaming(batman, mordern combat 4, death triger)- 2 - 2.5 hrs
intensive gaming(gangster vagas, nova 3)- 3 - 4 hrs
casual gaming(subway surf, temple run, cut the rope)- 4 - 4.5 hrs
s4 also heats a lot if you use your device in bright sunlight for 10-20 min its temperature will increase upto 40-45 degree.look at iphone 5 its feature just like an entry level phone but what a master piece.everything is fine.
dont buy this phone its overall performance is not good
battery and heating issue common in s4 but its too much heating like iron
fully disappointed .its better to go with nexus
