Last week, Ming-Chi Kuo, an analyst with KGI Securities, revealed a slew of features that are expected to arrive on Apple's upcoming iPhone 6S and iPhone 6S Plus models. Now, another research firm, Citi Research, has released data that confirms most of the KGI analyst's information.

Details of Kuo's disclosures can be found in a May 13 report by International Business Times.  According to Business Insider, Citi Research confirmed the following information about the Apple phones:

1 The iPhone 6S will come with a 4.7-inch display and the iPhone 6S Plus will house a 5.5-inch screen.

2. Like Kuo revealed, the much speculated 4-inch iPhone will not be releasing this year.

3. Both the iPhone 6S models will be coming with the Force Touch technology that has already arrived on the Apple Watch and MacBook Pro. The feature can help the device distinguish between harder and lighter taps.

4. Samsung will be building the Apple A9 chipset. The new chip will increase the speed performance by 25 percent.

5. Last year’s iPhone 6 models came with 1 GB of RAM, but the new iPhone 6S handsets will arrive with 2 GB of RAM.

6. Previous iPhone 6 models used to feature 8 MP camera. The newer iPhones will be featuring 12 MP camera.

7.  Apple was criticized for using low-quality aluminum in building the iPhone 6 and iPhone 6 Plus. Both devices were plagued with the “bendgate” issue. The forthcoming iPhones will come with 7000 series aluminum that is 60 percent stronger than regular aluminum.

Citi also predicted that the upcoming iPhone 6S models will be highly popular. It predicts shipment growth of 34 percent over the last year’s models.

The following features predicted by Kuo are unconfirmed by Citi Research:

1. There is no confirmation on a rose gold iPhone 6S color option.

2. Kuo claims that the iPhone 6S handsets will feature a sapphire display but Citi reports that both the devices will sport Gorilla Glass Corning 4.

3. Gesture control feature is also another prediction by Kuo that has been unconfirmed by Citi.

4. Citi has no comments on Kuo’s claim that the iPhone 6S and iPhone 6S Plus will come with improved Touch ID sensor.
