Apple's iPhone 5 launched on Sept. 12. It features a more powerful processor than its predecessors and sports a 4-inch display. Game developers may look at the new iPhone 5 as an improved gaming machine compared to previous models. The new A6 processor on the iPhone 5 will double the CPU performance of the device when compared to its predecessors. The powerful processor on the smartphone will improve game developers' ability to make better-looking games.

"It drives both the graphics as well as the speed of the game and the depth of the game," Earl added.

The 4-inch display of the iPhone 5, as opposed to the 3.5 inch display on the current iPhone 4S, provides users an improved visual experience while playing games. At iPhone 5's launch event, Apple demonstrated the game Real Racing 3, where game designers added side mirrors and rear view mirrors to the player's point of view.

"That makes a big difference to the game play and the immersion," said Rob Murray, executive producer of the game. Real Racing 3 is due to be released later this year on the iPhone 5.

Nearly 52 percent Apple iPhone users play games on their smartphone at least once a week, compared to 42 percent of Android smartphone users, according to Frank N. Magid Associates. Additionally, a recent UK study revealed that gaming is the fourth most popular activity among smartphone users which surpasses making calls (at the fifth position).

"Mobile is the fastest growing segment of the interactive games business right now, and Apple is a major driver of that growth. We're very closely aligned with them; we're number one in terms of market share across Apple devices. Every new phone and tablet spells opportunity for us to extend our reach to people who never considered themselves gamers," said Nick Earl, SVP and General Manager of EA's Mobile & Social Studios.
