Ming-Chi Kuo gives a research note revealing massive upgrades to be included in the upcoming iPhone 6s such as Force Touch, rose-gold color, A9 processor, and many more. However, the note did not mention one important feature that needs to be improved in the iPhone 6: the battery life.

Apple’s iPhone 6s and iPhone 7 are expected to come out with massive features such as Force Touch sensors, new rose-gold casing, upgraded 12 MP camera, and many more. But more than these, the gesture control, sapphire display, and additional RAM makes the iPhone 6s and iPhone 7 promising by the day.

iPhone 6s rumored to have 4.7 and 5.5 versions with better housing. Its expected to be released in September.

As the release date of the next iPhone version draws near, two schools of thought are still at loggerheads whether Apple should release iPhone 7 this year or iPhone 6s. However, the release date of the iPhone 6s and iPhone 7 is decided by the “tick-tock” approach.

A data shows that 5% still prefer smaller iPhones, which constitutes to a 10 million potential sales. Apple may release three new iPhones this September, iPhone 7 Mini, iPhone 7, and iPhone 7 Plus, in order to cater to the 5%.

Rumors, analysis, and a recent leak point to an iPhone 7 that is going to be 60% stronger, without a 4-inch version, and may come out with a flexible display this year.

Apple made a “last-minute decision to recruit TSMC.” This was due to three reasons such as Apple’s concern over Samsung chip production. Coupled with a 2 GB of RAM, the chip is said to potentially offer “between 135% and 161% more performance.”

An analyst claimed that the Force Touch technology would prompt Apple to skip iPhone 6S, and instead release iPhone 7 this year. However, a German retailer listed the iPhone 6S in their online catalog, implying that the device will be released this year. In view of these recent rumors, a table will show the difference between the two devices.
