I am big fan of Apple iPhone 5s. I am using this since 1 year. It is a very good phone battery backup is good more than previous iphones like Iphone 4, 4S or 5, 5c. Sound Quality is very good. Gaming experience is also awesome.
The best thing of this phone is its looks, Metallic Look. It looks like a chocolate. There is a bio metric lock that is superb edition in this phone. Siri is also awesome and Sound Quality is also awesome.
