The most important requirement for a cell phone is its handling ability and its features. With iphone 5s its a complete mix when its comes to handling and seeing the features. It operates on ios with a brilliant camera quality. Good battery life adds to its pros.
The only drawback is to find the original spare parts for this phone as apple in itself is a huge company so if the screen gets broken orr something I would suggest to use only the real ipjone parts. It will add to its life.
