Last Sept. 9, Apple unveiled their newest product lineups to millions of fans around the world, including the successors to the iPhone 6 and 6 Plus. 

At first glance, it seems that the designs and body works of recently-unveiled iPhone 6s and 6s Plus are not that different from their predecessors. However, Apple observers took a closer look and noticed subtle changes in the two new smartphones. Aside from offering two new colors – regular gold and rose gold hues – the 6s and 6s Plus are also slightly wider than the previous iterations. 

Meanwhile, the display for the new devices remain the same, with the 6s having the same 4.7-inch, LED-backlit widescreen offering 1334 x 750 pixel resolution at 326 ppi. The 6s Plus, on the other hand, has a 5.5-inch, 1920 x 1080 pixel resolution at 401 ppi display. However, a new additional feature was put in by Apple – the new iPhones now have Taptic Engine that unlocks 3D Touch options. Similar to the Force Touch technology on the Apple Watch, users of the 6s and 6s Plus now have access to more options and features of apps with a single tap, press, or click, with the display able to tell the difference in pressure for each. 

As with other S variants offered previously by Apple, most of the upgrades to the 6s and 6s Plus were integrated inside the devices. Both smartphones use the newer and proprietary A9 chipsets, are upgraded with 12 MP iSight cameras, and feature LTE Advanced wireless connectivity. The iPhone 6s and 6s Plus have also been upgraded in terms of storage options as both now have 128 GB versions. 

The iPhone 6s and 6S Plus will be available on Sept. 25, with pre-orders starting on Sept. 12.
