The iPhone 6S is rumored to be Apple's next smartphone offering. There are lots of speculations as to how this device will be, yet the reports say the same thing: The new iPhone will be run by an A9 chip. As to who will supply the said tech is a big question.

It's an old story that Apple and Samsung are in competition when it comes to producing the world's number 1 state of the art phone with mind-blowing specs and features. What's new is that this time, the two are reportedly working together. According to Digital Trends, these rivals teamed up for the A9 processor which will then be featured in iPhone 6S. The production is said to have begun in mid-December.

Despite the news that Samsung will supply the processor of the next-generation iPhone, another company jumped into the scene. According to Mac Rumors, Taiwan Semiconductor Manufacturing Company (TSMC) will supply 30% of the chip orders.

The following statement was said to be from a reliable source, KGI Securities analyst Ming-Chi Kuo.

"We believe key reasons in Apple's (US) last minute decision to recruit TSMC are: (1) unstable yield rate at GlobalFoundries (US); (2) TSMC's 16nm FinFET Turbo has exceeded Apple's expectations in yield rate and performance; and (3) concerns of insufficient 14nm supply from Samsung LSI (KR) due to better-than-expected market feedback of Galaxy S6 and S6 Edge, which uses the in-house 14nm FinFET-manufactured application processor Exynos 7420."

Citing Ming-Chi Kuo, Mac Rumors further explained that GlobalFoundries, Samsung's manufacturing partner is said to have 30% unstable yield rate of the A9 chip, which is below 50% yield rate required for Apple's mass production, and this resulted to Apple's last minute decision. 

The last-minute switch of decision could also be blamed on Galaxy S6's demand. According to The Inquirer, Samsung may not be able to match the demand that Apple needs, with Samsung supplying the 14nm chips inside their own Galaxy S6 and Galaxy S6 Edge, and this reportedly concerns the Cupertino-based company.

As for other specs and features, Mac Report noted that the new iPhone will have a Force Touch display. New gestures will then be expected. Moreover, iPhone 6S could be made with 7000 series aluminum. With this material in use, the new iPhone will be durable and scratch resistant, as well as light in weight. Some improvements were also made: the Touch ID Fingerprints will be detected anywhere on the display and it can detect multiple fingers at once, or even the whole palm for enhanced security.

When it comes to looks, the iPhone 6S will still be the same as current iPhone 6. PC Advisor reported that iPhone 6S will use the same chassis and will come in same color options. The screen size will most likely be the similar to an S model, about 4.7in. Regarding the resolution, the new device could sport 400ppi with 5in display.

Apple usually launches products in September or October but a report from iDigital Times claimed that the iPhone 6S release could be delayed. The reason for such delay was thought to be caused by strong sales of the current iPhone 6 and 6 Plus as Ming-Chi Kuo had also predicted.
