A new rumour claimed that the alleged low-cost iPhone 5S will come with 3.5-inch screen display like with the iPhone 4S's. Moreover, the device is also speculated to be available in different colour variants similar with the 5th generation of iPod Touch.

It seems that Apple is jumping in the bandwagon of releasing affordable handsets to expand its target market. According to the sources cited by Taiwanese tech-business Web site DigiTimes, tech giant Apple is set to release the rumoured cheaper iPhone 5S with 3.5-inch screen display on Q3 2013.

Thus, many speculated that the flagship iPhone 6 may retain the current screen size of iPhone 5, which is 4 inches.

Recent leaks from the Apple supply chain indicated that the handset would retain the four-inch screen of the iPhone 5, with cost-savings coming from substituting premium materials for a plastic shell and skimping on processor brawn.

Another rumour about the low-cost smartphone from Apple is that the device will be available in different colours like its cousin iPod Touch 5th Gen. Purported images of iPhone 5S leaked online over the past weeks claiming that the iPhone 5S is true and is, indeed, coming.

However, Apple CEO Tim Cook initially said in his D11 interview that Apple is not working on a low-cost smartphone and will not release such device in the near future.

Rumour has it that the next iPhone will include a faster A6X processor, larger storage capacity up to 128GB, added security feature such as the fingerprint sensor and longer battery life.

The alleged low-cost iPhone, on the other hand, is rumoured to have the specs of either the iPhone 4 or iPhone 4S and will be available in a variety of colours.

The devices are expected to make its debut later this year. Rumour has it the smartphones will be released in September.
