Apple may hold the much awaited iPhone 6 and iPhone 5S release date on September 11, which is the National Day of Mourning.

Reports claimed that iPhone 6 and iPhone 5S release date may happen on September 11. This is based on the predictions of a well-known analyst of Apple devices.

According to the latest note from reliable analyst Ming-Chi Kuo of KGI Securities, a new iPhone will be released in early September. Kuo proved to have correct predictions and analyses when it comes to Apple devices. According to his latest note, two Apple smartphones are coming later this year.

Apple may announce the iOS 7, the iPhone 6 and the iPhone 5S at a launching event on September 3 and release the iOS 7 and the devices about one week later on Sept. 11.

However, other reports claimed that iPhone 6, iPhone 5S release date will happen in other days of September. There are guesses that iPhone 6 release date will be on September 13, while the iPhone 5S release date will happen on September 27.

Consumers know that the iPhone 6, 5S release date is coming very soon as the iOS 7 beta 4 was just released. IBTimes AU reported that the full-fledged iPhone will be released in September as the Gold Master version of iOS 7 will also be released around the same time.

Aside from the new iOS 7, Apple's iPhone 6 is speculated to be powered by A7 quad core chip. It will include some features such as Near Field Communication, 13MP back camera and longer battery life. And just like its brother, iPad, it may have a large internal storage of up to 128GB.

Meanwhile, the cheaper iPhone 5S is expected to boast a 4-inch screen display, a dual core processor and an 8MP back camera all housed in a cheap plastic casing. However, based on Kuo's latest note, we can expect that the low cost iPhone may boast the features of iPhone 5.

However, we should still wait until Apple officially announced the release date of its devices.
