The latest expectations for Apple's next iPhone

If the latest Apple iPhone rumors are true, the next model will have stereo speakers, a dual-lens camera and a slightly thinner design than the iPhone 6S, according to recent reports.

In addition, the new iPhone is expected to have a thinner lighting jack and no 3.5-millimeter headphone jack, Mac Rumors reported, citing Japanese website Mac Otakara. The details about the new phone's size echoed a similar report from a KGI analyst last year, Mac Rumors said.

The phone, which is not formally called the iPhone 7 yet, is expected to be unveiled at an event in September.
