We are in 2016 where all are talking about most powerful smartphones.
But I going to tell you my opinion about Iphone 5s which was announced in September 2013.
Things I love about this phone is it is still very powerful phone in terms of performance. Even if you are doing multitasking on it, it feels absolutly lag free and gives you great performance.
Talking about its camera, it has 8 MP isight rear facing camera and only 1.2 MP front facing camera.
you can take very decent photos from rear camera and talking about front facing camera you take good selfie too although it has only 1.2 MP front facing camera.
Talking about Its software and hardware.
In 2016 if you get iphone 5s you will get IOS version 9.3.3 but you can upgrade it to the latest version of IOS which is 10.1.
Its has Apple A7 chipset which a dual core CPU clocked at 1.3 GHz.
Its is 1 GB of RAM which gives you great preformance even if you do lots of gaming and multitasking.
Iphone 5s also has the Touch ID sensor which makes Iphone 5s first ever Iphone with Touch ID ( Fingreprient sensor) .
The only thing I least like about This Iphone is the slow touch ID sensor as compare to other iphones or competitors.
At the end if you want to buy iphone 5s in 2016 because you dont have an iphone before then you should go for it, it is very very good phone in 2016 also.
