Apple is expected to buck the trend of larger iPhones phones by releasing its smallest version of the device in recent memory on Monday.

Speculation is the new device, which is expected to come at a lower cost, will measure just four inches diagonally, 0.7 inches smaller than the iPhone 6 and a full 1.5 inches smaller than the 6 Plus.

Apple CEO Tim Cook is expected to announce the change in direction at a Monday keynote press conference. The announcement comes just two years after Apple released its largest iPhones ever, in keeping with a trend toward larger models championed by rivals like Samsung.

Apple Bucks Trend

"While people like the bigger phones, there are devotees of the smaller phones simply because of different-sized hands and pockets," said Frank Gillett, a Forrester Research analyst.

As more of the younger generation of iPhone users navigated to Samsung, which featured screens nearly as large as those on tablets, Apple abandoned earlier plans for devices with screens as small as 3.5 inches.

The iPhone 5 is currently Apple's smallest version at 4 inches. Meanwhile, the iPhone 7, officially scheduled to launch later this year, is expected to feature several sizing options like the iPhone 6. With the change of direction, Apple is hoping to generate buzz in the industry that could translate into increased sales.

"By taking the electronics from a newer phone and moving most of it into a smaller phone, they can update the look and preserve the choice for consumers," added said Gillett.

The new phone is said to combine the iPhone 5's smaller dimensions with the iPhone 6's updated features, such as improved camera, faster processor, more power and improved battery life.

Battle for Consumers Drives Down Prices

By offering a cheaper phone, Apple is also hoping to win consumers in emerging markets who feel iPhones in general are just too expensive.

"There are a lot of places around the world that don't enjoy what we have here in the U.S. in terms of economics and infrastructure," said Brian Blau, an analyst with research firm Gartner. He added Apple has built its worldwide reputation on offering premium devices at commensurate prices.

"But it doesn't meet everybody's needs globally," he added.

iPhone sales in the U.S. and Europe have stagnated recently. The company generated $234 billion in worldwide sales last fiscal year.
