Early rumors suggested that the next generation iPhone could have a dual lens camera that would greatly improve photo quality. While this is not the case, the iPhone 6s iSight and FaceTime cameras have both been upgraded.
The iPhone 6s and iPhone 6s Plus are powered by the new, speedier A9 system-on-a-chip (SOC). The 64-bit A9 SOC uses new transistor architecture to optimize daily processing tasks. The M9 motion processor is embedded in the main chip and always switched on.
The iPhone 6s is much faster than the iPhone 6, which utilizes the previous A8 processor.
The iPhone 6s and iPhone 6s Plus ship with iOS 9.
iOS 9 release date is September 16. iOS 9 features improvements to Siri, Apple Pay, Photos and Maps, plus a new News app. It will also introduce a new app thinning technology that could give you more storage capacity. A new low power mode could significantly improve battery life as well.
Yes, the iPhone 6s and iPhone 6s Plus have the same external case design. "S" series updates in the past have largely concentrated on improving hardware, and the current update follows suit.
Apple's manufacturing partners Samsung and TSMC have begun mass producing the A9 chip that will power the next generation iPhone, according to a report from Taiwanese tech newspaper DigiTimes. Though Apple reportedly issued last minute modifications to the chip layout that prompted both companies to rework the wafers, the launch timetable supposedly remains on schedule.
