Iphone 6s used almost 4 years

As i bought a new iphone, i wnat to sell this oldie which is good to use. Just that it is 4 years old, it works in a good condition; however, the battery life is 3/4 hours so you have to keep the powerbank if you use the phone very much. No scratch on screen, it is the screengaurd having a little scratches. Comes with 3 used cases, green, black and pink
