I have been using apple iPhone 5s since last 2 years and still now I am using the phone. The phone is small and compact obviously not the best for watching videos/movies or playing games, but the phone definitely has one of the best screens around. No eye strain even after using the mobile for several hours at a time. Single handed usage is possible and the handling is great. Also the phone build quality is so good that even after using it for 2 long years, no one would say that it is such old phone. Just few scratches and one small dent after 2 years. Now talking about performance, you will definitely see a minor 2-3 second lag every now and then. Even when using safari browser, when you are switching tabs, you can notice lags. Also while opening Facebook app or whatsapp you can see white screen for 4-5 second only then the app starts loading . Also the basic camera app also takes 5-7 seconds to launch the camera. But it is ok for a 2 year old phone. My phone is also updated to IOS 9 and the one thing worth mentioning is that the phone still gives battery backup of about a full day with normal usage. Camera is also still one of the best with good details and natural pictures. Fingerprint sensor is fast and accurate. Definitely worth its price
