Earlier this week, The Wall Street Journal reported that Apple (NASDAQ:AAPL) is releasing two new iPhones this year with larger screens, a 4.5-inch model and a 5-inch-plus model. While this wasn't exactly new information, it was more evidence from a reputable source that big iPhones are on the way. The report also said that Apple is "scrap[ping] the plastic exterior" used in the iPhone 5c. There has been no shortage of reports suggesting that the 5c doesn't sell well, and larger iPhones would target an even higher end of the market, so it makes sense that the company would use premium metal casings for these phones, rather than plastic like the 5c.

In this segment of Tech Teardown, Erin Kennedy discusses the two new rumored phones with Evan Niu, CFA, our tech and telecom bureau chief. Shares of Apple rallied on the news, which shows that investors are pretty excited about a larger iPhone. Evan tells investors why now is just the right time for the company to release a larger version of its iPhone, in order to stay competitive with Samsung.
