Why Apple would retire the iPhone 5. A recent report states that the iPhone 5’s in-cell touch-screen technology would not be compatible with low volume production. It is generally believed that Apple will abandon production of its iPhone 5 in favour of its high end successor, assumed to be the iPhone 5S, and a rumoured low end, less expensive plastic backed model dubbed as the iPhone Lite. It is believed that production on the iPhone 5 sucessor has already been begun. Having a high end and a lower cost model might explain why Apple would send its best selling phone, the iPhone 5 to early retirement.
