Hi
I personally use iphone 5s silver grey I really love this phone.
I have purchased it 6 months before
first of all: battery is upgraded to 1560 li- po its last long comparing to other models like 4s, 5c 5.
and you can enjoy screen quality with retina display . pictures and videos are very bright in this model . and security upgraded with Fingerprint Sensor you can lock your phone and apps store purchases with this security tweak .
and its supports latest ios operating system 10.0.2 and upcoming os’s.
things I really liked about this phone: 1) battery
2) finger print sensor 3) camera quality 4) screen quality(comparing to other 5) Design .
