iPhone 6 Release Date Pushed Back Due to Issues With Battery

The launch of the 5.5-inch iPhone 6 has been pushed back due to issues with its battery.

Apple is struggling to find a sufficient battery that measures at 2 mm or less that will fit the device's "very thin" profile, according to a new report from Taiwan's Industrial and Commercial Times.

The report also states that Apple suppliers are calling the 5.5-inch model the "iPhone Air." This device would join Mac's line-up that also consists of an iPad Air and a MacBook Air.

The iPhone 6 release is now rumored for September as components for the device are starting to be manufactured in preparation for the date. This could still end up being the launch time for the 4.7-inch iPhone model.

A previous report from the Japanese business newspaper Nikkei claims that manufacturers have already begun making fingerprint sensors, liquid crystal drivers and chips for the device.

Mass production of LCD panels will start as early as next month at Sharp's Kameyama factory, Japan's Mobara plant along with other locations, according to the sources. The new models are expected to have much higher resolutions screens than the ones found on the iPhone 5s and 5c.

The paper also claimed that the next-gen iPhones will be offered in 4.7-inches and 5.5-inches.

Another rumor pointed to Apple only launching one of the two sizes this year. UBS analyst Steve Milunovich stated in a research note that Apple is definitely working on two different models, but isn't sure that both will be released in 2014. He agrees that Apple will launch the new iPhone around September, but might hold off on the larger iteration until next year.

Judging from all of these different stories, it seems that Apple will definitely launch one new iPhone this year.
