I still have a 5S. After over three years of use, the battery has 326 cycles and the capacity is at 82%. It's been a great phone and I still use it today. I ordered a 64GB SE from T-Mobile on Friday that will be here Wednesday. I've always liked the 5S look and I can't wait to start using the SE. I'll probably just put the 5S away in it's box when Wednesday gets here.
