IPhones are the most powerful phones from the very beginning and the reason is very clear. Here’s a detailed review of iPhone 5S.Size : 5s according to me has the perfect dimensions. The phone can easily fit in your palms and you can even operate it with one hand.Camera : The camera in 5s is one of the best cameras in that range, you can take some stunning and vibrant pictures from the phone.Battery life : One’s completely charged it can last upto 7 to 8 hrs but it depends on your usage.Speed and performance : I’ve used 5s for 5 to 6 months but I never faced any performance issue. It was always top notch.Sound : The best thing about sound is the speakers are on the bottom part so you can keep the phone either upwards or down wards it’s fine.Cons: The only reason I considered switching from 5s was single SIM else it is a perfect phone.
