I have been using my iPhone for past 5-6 months and I am pretty happy with its performance. This is my first ios device earlier I used only android and thought it is the best. Ios devices has one plus point i.e. the operating system doesnt require alot ( in terms of ram, processor, etc) , they run smoothly if it is iphone 4 or 5 and above they still run perfectly smooth. Apple also provide quality so all in all its a perfect phone. But there is one conc. i.e. Ios 10. It just ruined my battery performance now I want to downgrade to Ios 9.
