In my view the best from Apple to date.was waiting to buy one from the day of launch i.e. September 2015. This comes with the option of 16, 64, 128 GB of ROM and 2 GB ram. The camera is good with a primary camera of 12 megapixels with dual LED flash and secondary 5 megapixels.
Screen Is 4.7 inches which are good and handy, easy to hold and doesn’t make me feel uncomfortable with the size.its not too big nor too small. perfect fit in hand.
Battery backup is good as compared to previous iphones. and it surely is fast with OS 9 which is upgradedable to 9.3 with apples latest A9 chip, making it really faster and they offer best colors in which mine favorite is the one am using the space grey. really good one with good value and satisfaction.
