Finally had to admit that my 5s had reached the end of its life. The battery was completely useless and the phone had slowed down appreciably. So yesterday, I traded it for an iPhone 7 128Gb, which I promptly filled to ¾ capacity with music. This will be my 4th iPhone, having started back in the long-forgotten days of iOS 4.1.3 and an iPhone 4. The 5s replaced that, and until recently, I had an SE courtesy of my employer. With a trade in of $100, the 7 came more or less free, which is how I like my phones. Apart from the size of the thing, it seems very familiar, so I'm not expecting any surprises.
