Well i have sold 4 i9505 and used one of them and now on i9500. Personal experiance the i9500 is snappier with more screen on time. Gives me around 4.5 hours.
The reason i bought i9500 is bcoz its better than i9505 and I dont need LTE. The samsung 1.6 ghz chipset is very powerful one. Go and watch their comparison by Errica Griffin on youtube. Even in games i9500 is more smooth. There is also i9506 that came with snapdragon 800 but its too expensive. And 2.3 ghz wala i9505 bhai yaar i stopped reading ur comment after u said this. [emoji15]
