This phone is such an amazing phone when it comes to the sceeen size and all the features. The phone comes with a 4.00-inch touchscreen display with a resolution of 640 pixels by 1136 pixels at a PPI of 326 pixels per inch. I have experienced that a lot as I have a habbit of forgetting it to put it to charge at night. if u leave the battery at 1% all night provided notifications turned off I can bet a whale it would be on when the morning comes. iphone introduce so many unique features like finger print scanner, metal body, best picture quality, opreating system.
