I have used iPhone 5s near about 6-7 months.
This phone has 1 gb of ram but it can beat other phones having 3 gb of ram phones if we compare speed and complicity. I never faced any hanging issue with this phone.
If someone do not prefer to large screen phone so IPhone 5s is the best option in iphone series. It’s very easy to use this phone one handedly due to its design and 4.5 inch of screen size.
Camera quality of this phone is also good as this phone has 8 megapixel back camera but it can beat samsung’s 12 megapixel cameras when compared with their picture quality.
Overall if you want to use a iPhone and your budget is low then this phone is best and this phone gives a real feeeel of iPhone.
