I have been using iPhone 5s from last 6 months. When you start using ios devices, you will surely foeget about other devices.
The Camera has given in Iphone 5s is 8mp rear and 1.2mp front ( i.e. more than 8mp of any other mobile) .
The speed is superb.
I’ll recommend you to buy 32 gb one. Not less thsn that. The headfones are fab. As apple always maintains the quality.
The major factor on any mobille is battery. So here apple has given 1640mah battery on iphone 5s. That is enough for normal user. It stands a day if you are using it normally.
Finally i’ll highly recommend this to buy even in 2017.
