Apple will be unveiling its latest devices in a couple of days in the company's special Sept. 9 event. The iPhone 6S and iPhone 6S Plus were the ones that got a lot of attention from waiting tech users.

Considering that it was only a year ago when the Cupertino tech giant opted to use a new design, it is highly likely that the upcoming iPhone units will not show any significant differences from its recent predecessor. Apart from being slightly larger than the iPhone 6, it is also expected that the devices will be thicker, too - most likely because of the added Force Touch technology.

It must be noted, however, that under the hood, the aforementioned two devices have been completely revamped.

As mentioned, the iPhone 6S and iPhone 6S Plus will be featuring a Force Touch technology - a feature that was first introduced via the Apple Watch, according to The Verge. With this new technology, users are given access to an additional layer of input on the smartphone's screens. By touching the screen, hold-touching it, or pressing down very hard, a variety of smartphone options can be accessed - depending on how much pressure was applied.

There is also a possibility that the feature will be renamed for the iPhone. According to 9To5Mac, Apple has its sights set on naming the feature "Deep Press."

Tech Times has also pointed out that the iPhone 6S and iPhone 6S Plus will also have an improved camera. The upcoming units will reportedly boast of a 12-megapixel camera with optical image stabilization, as compared to the 8-megapixel photo snappers that were featured in the last four iPhone models. In addition to that, the camera located on the device's front portion also got upgraded to 5 megapixels.

Furthermore, the Internet is also abuzz with reports that the upcoming iPhones will also be available in a rose gold variant. With this new color, iPhone 6S and iPhone 6S Plus users can match their new smartphone with their new rose gold Apple Watch.
