Apple probably won't ship out its next iPhone with a reversible version of the Lightning charge cable or with a larger, possibly more powerful iPhone power adapter, according to analyst Ming-Chi Kuo.

"We don't expect the USB power adapter and Lightning cable for iPhone 6 to have significant design changes," Kuo wrote in a Monday morning note to investors, according to AppleInsider. 

Kuo said the reason the new phone won't come with either is because of the "cost concerns and limited improvements to overall user experience that such changes would bring" before calling the speculation "off the mark."

Rumors of a new Lightning cable with a non-standard, reversible USB Type A plug at one end was first reported in mid-August.

A number of parts with the new design have appeared online recently, but such a configuration is not currently sanctioned by the USB Implementers Forum, the USB standard's overseers.

A new U.S. power adapter with a larger physical design that matches the current-gen adapters for Australia popped up on Chinese microblogging site Sina Weibo.

Similar adapters were also seen for Europe in another report.

All rumors will be put to rest next week at Apple's highly-anticipated media event.

Apple officially invited media last week to an event in its hometown of Cupertino, California, on Sept. 9, when the company is expected to debut the latest iPhone.

The company is expected to debut a larger 4.7-inch and 5.5-inch iPhones at the event, a move that could be driven in part by the success of larger devices by rivals like Samsung Electronics.

The device will run on Apple's next-gen iOS 8.

Rumored specs for the next iPhone includes: 1704 x 960 pixel resolution, a faster A8 processor, camera upgrades, and a more durable, sapphire screen.
