Which iPhone to buy

The iPhone market is unstable in India right now as the iPhone 6 and 6 plus have nit come yet and the earlier iPhones are getting cheaper. I will advise all of you to not think about buying an iPhone right now. Please wait till the new iPhones come in India. If you plan to buy a new iPhone from abroad then keep only iPhone 5s, 6 and 6 plus as choices. The earlier iPhones even iPhone 5c are not worth buying as apple has been using 64 bit chips for over a year and now some amazing apps and games are coming only for A7 and A8 chip which have a 64 bit architecture. The screen size can be the most important decision factor as the three iPhones have a screen of 4, 4.7 and 5.5 inch respectively. When it comes to performance then they are at the same level, with of course the A8 devices a little above the A7 one. The cameras of the 6 are better than the 5s, especially when it comes to slow motion video recording. The 6 can record in 1080p in 60 fps and in 720p in 240 fps, double than the capacity of the 5s.
