I love the iphone 7.i'm using this device from from the last 8 months, it has a very impressive battery life and it never got hanged also.it is also very user friendly as it has a standard and very good size( the perfect size a phone should have) .The style and design of the phone is also very good, I love that jet black colour of the phone.It also has very attractive and impressive features. As far as the sound is concerned it does not have a very loud sound and I think in this matter apple has done better in yhe iphone 6s.Its eorth in that price.
