8. iPhone 5S
Until the successor had been released into the market, the iPhone 5S was among the most popular smartphones in the whole world. Now it holds the 8th place, because of the immediate success of the iPhone 6. The iPhone 5S is actually the 7th generation of the iPhone line, developed by Apple Inc. Still, it is one of the best smartphones you can find, and the price stands at about $530. The price could be the reason for not selling that much in India as in the rest of the world.
