Apple iPhone is known for its optimization and processing but there are some cons of it like 1) big size - I am mainly a Android user and my Phone has a screen and bandwiths of size that I can hold in one hand and use it but with iPhone I have to use my both hands. 2) Screen resolution - iPhone still have screen of 720p where android have got amoled and oled screens for phones. 3) No fast charging - Android phones have got fast charging support and I can charge a phone of more battery than iPhone in 90min. Where as an iPhone will take 2hrs. 30 min. to 3 hrs.
