Apple is widely believed to introduce two new smartphone models during a launch event next month, the iPhone 6S and iPhone 6S Plus. However, fresh rumors now suggest that the tech giant actually have three models in store; the third one being the smaller, more reasonably priced iPhone 6C.

Last week, we wrote that Apple may be planning to release their affordable iPhone 6C model next year. That was based on a report by a Taiwanese publication citing industry sources. Now, renowned leakster Evan Blass has spilled the beans once again. He recently tweeted that the smaller Apple smartphone will come earlier than expected.

On Tuesday, he mentioned via his @evleaks Twitter account that the iPhone 6C will be unveiled simultaneously with the other two larger iPhones. His exact words were: "Sounds like iPhone 6s, 6s Plus, and 6c will all arrive concurrently." That implies that the three models will be revealed during Apple's September event.

This is the latest in a series of speculations claiming that the Cupertino-based company is looking to offer a new 4-inch budget model, having abandoned that lineup this year when the company made the jump to the iPhone 6 and phablet-sized iPhone 6 Plus.

On the specs department, the iPhone 6c is said to pack an advanced "FinFET" chipset. The tiny processor will use either a 14nm or 16nm technology manufactured by Samsung or Taiwan Semiconductor Manufacturing Company (TSMC), respectively. The new chipsets are said to provide more efficient performance and lower power consumption.

Speaking of power, the upcoming smaller iPhone model is expected to be kept running by a 1,715mAh battery. The device is also rumored to sport a more premium all-metal form factor instead of the all-plastic body of the current iPhone 5C.

Apparently, the statement from @evleaks is not official. Blass has been wrong a few times before, but his predictions and leaks were usually accurate so we only have very little reason to doubt him this time. On the other hand, the other leak indicating that the iPhone 6C will arrive next year comes from analyst Ming-Chi Kuo, another reputable source for Apple product leaks. To have conflicting forecasts from two reliable sources pretty much make the iPhone 6C more enigmatic.

Having said that, it's best to just take this new information with a grain of salt. After all, Apple's iPhone announcement will reportedly take place on September 9. That means we only have to wait for a few weeks to know which of the rumors are correct.
