I am using iphone 5s science 7 monthS.
Its a good smartphone with 4.00 inch display powered by 1.3GHz processor 1 gb RAM 8megapixel camera. IPhone 5S appears to be very well presented device and new attractive design speaks for it . Mejor change lie inside the device .
A new 64-bit cortex A7 clocked at 1.3GHz gives it an extra boost in power with 40% less battery consumption. And the body weight of it is very cool light weight easy to grip.
