Will Apple Release a 4-inch iPhone Next Year?

Apple, fresh off releasing the mega-sized iPhone 6S and even larger iPhone 6S Plus, is considering downsizing to a 4-inch device, according to one analyst.

The 4-inch phone would resemble an "upgraded iPhone 5S," said KGI Securities analyst Ming-Chi Kuo in a note to investors obtained by Mac Rumors. It could feature the same A9 processor as the iPhone 6S, he said, but not the 3D Touch feature.

Unlike the iPhone 5c, the less expensive alternative to the iPhone 5S released in 2013, this device would have a metal casing instead of one made from plastic.

According to Kuo's predictions, customers should expect three new iPhones — a 4-inch, 4.7-inch and 5.5-inch model — in 2016.

NBC News reached out to Apple and Kuo for comment but neither replied.

While plenty of people try to predict upcoming Apple products, Kuo is known as one of the more reliable analysts, correctly stating beforehand that Apple would release a 12-inch MacBook, the iPad Pro, and larger 4.7-inch and 5.5-inch phones. That doesn't mean, however, that his prediction will pan out.

Before the release of the iPhone 6, plenty of analysts were saying that Apple would release a 4-inch iPhone 6, which never happened.
