Performance :

This model holds an A10 Fusion chip which has four cores with two high-performance cores and two low power cores which  use less power for the everyday tasks.Apple impressed  with its faster processor which consumes less power to previous versions.  The water resistant feature is good but needs a lot of improvement when compared to the Samsung phones. This user-friendly smart phone is incredible to use and works pretty well compared to the older versions. Hope Apple will correct the mistakes and provide new design tweaks in the next versions.
