It seems that tech giant Apple is ramping up the production and preparations for the new smartphones dubbed as iPhone 6 and iPhone 5S in order to meet the rumoured September release date of the devices.

Apple is working hard on the specs and features of the new smartphones. Apple is seen to dispatch new chip architectures via its A-series processors, which according to experts will showcase new GPU capabilities that likely resemble or exceed the prowess seen before in AMP-powered mobile devices.

Apple purchased Florida-based biometrics security firm Authentec last year. This could mean that Apple is adding a better security feature on the smartphones such as the rumoured fingerprint sensor.

However, there are reports that the next iPhone is experiencing production issues. A number of analysts claimed that Apple's smartphones are delayed due to "production issues". However, recent reports also claimed that Chinese suppliers already received the components needed in building the iPhones.

Latest reports stated that the delay in iPhone 6 and iPhone 5S release date can be blamed to Foxconn workers committing suicide.

Foxconn is Apple's partner in China that is charge of the mass production of Apple devices. However, the Chinese company is clouded by controversy because of reports of unfavourable working conditions.

Controversy surrounding Foxconn's working conditions, particularly "iWorkers" who make up the Apple production force responsible for pushing out new devices like the upcoming iPhone 6 and iPad Mini 2, continues to grow as reports are surfacing that three Chinese labourers in the Taiwanese companies' factories have allegedly committed suicide.

However, a Foxconn representative denied the reports and made a statement on Monday, claiming that none of the three reported death were due to work conditions or related in any way to work, as they all took place outside the walls of the Foxconn factories. In addition, one of the three supposed suicides was by an employee who was a new hire and had not yet even begun his first day on the job.

It is initially reported that the new iPhones will be launched in June along with the upgraded iOS. However, other reports stated that the devices will make its debut in September.

The Apple chief Tim Cook also dropped several hints that the upcoming iPhone 6 and 5S will be released later this year. Cook said that no new products are to launch before the end of the year.

Cook also subtly dented rumours that the iPhone 5S could launch as early as June. "Our teams are hard at work on some amazing new hardware, software, and services that we can't wait to introduce this fall and throughout 2014."

Moreover, the discounts on the current iPhone 5 signal the imminent release of the next generation of iPhone. Apple made a partnership with U.S. Retail Giant Best Buy for a new deal that allows buyers to get $US150 price off on an iPhone 5 Purchase. Customers just have to trade there in their old iPhone 4 or iPhone 4S handsets to avail of the discounts.

The deal was offered a week after Best Buy swung the same iPhone 5 kit for only $US149, cutting down from the usual $US199 asking price that network providers slapped on new iOS smartphone releases. Rumour has it that the next iPhone will feature Retina or IGZO screen display, A7 quad core chip processor, iOS 7, 128GB internal storage, 13 mega-pixel camera, and longer battery life. The lack of NFC support on the iPhone 5 was one of the biggest criticisms aimed at Apple's smartphone.

Meanwhile, the cheaper iPhone 5S is rumoured to sport a plastic casing, 4-inch screen display, dual core processor and 8-megapixel camera.

However, Apple did not give an official statement on the rumours surrounding iPhone 6 and iPhone 5S.
