While there is no increment in screen size in iPhone 6S (4.7-inch HD) and iPhone 6S (5.5-inch Full HD) compared to last year’s models, the phones feature a new 3D Touch display technology, which allows the screen panel to differentiate between types of touches and taps in preloaded apps as well as on the homescreen.
Both iPhones are powered by the new A9 processor with 2GB RAM (reported) and run iOS 9 operating system. The new 64-bit A9 chipset is 70% faster at carrying out processes than the one on last year’s iPhones. Similarly, the graphics processing will be 90% faster.
While the phones come in 3 storage variants – 16, 64, and 128GB, there is no support for microSD cards for storage expansions.
One of the biggest upgrades to iPhone 6S and iPhone 6S Plus is in the cameras. The rear cameras of the two smartphones have 12MP resolution, backed by dual-tone dual-LED flash, while the front cameras have 5MP sensors. A new camera feature of iPhone 6S and iPhone 6S Plus is Live Photos, which can turn photos into short videos. The rear camera has also got 4K recording to capture high-resolution videos.
According to Apple, the iPhone 6S delivers up to 14 hours talk time on 3G and up to 10 days standby time. The 6S Plus offers up to 24 hours talk time on 3G and up to 16 days standby time.
The new iPhones feature faster-second-generation TouchID sensor and are made of tough aircraft grade aluminium, same as Samsung Galaxy S6 and S6 edge.
