The iPhone 6S and iPhone 6S Plus are evolutions over their respective predecessors, featuring improved hardware specifications, including 3D Touch, a force-sensitive touchscreen; upgraded rear-facing and front-facing cameras; a faster processor; a new chassis made of a stronger alloy of aluminum; second-generation Touch ID; improved LTE and Wi-Fi connectivity; and a new rose gold finish in addition to the space gray, silver, and gold finishes found on the previous models, while maintaining an identical design. The devices ship with iOS 9 preinstalled.
As of September 28, 2015, 13 million iPhone 6S and 6S Plus models have been sold, setting a new first-weekend sales record, up from the 10 million iPhone 6 and 6 Plus units sold the previous year.[11]

[hide]History[edit]
Before the official unveiling, images of the iPhone 6S were leaked online. Although unofficial, the leaks confirmed several of the phone's features. Some of these leaked features included the iPhone 6S model that has 16 gigabytestorage, a new near-field communication processor, and fewer chips compared to the older models of the iPhone.[12]
The iPhone 6S and iPhone 6S Plus were officially unveiled on September 9, 2015 during a press event named "Hey Siri, give us a hint."[13] at the Bill Graham Civic Auditorium in San Francisco.[10][14] Preorders for the iPhone 6S and the iPhone 6S Plus started on September 12, 2015. Both devices became available in stores on September 25, 2015, starting at $199 and $299 on a two-year contract, $649 and $749 off-contract.[15]
During the release weekend, 13 million iPhone 6S and 6S Plus models were sold that set a new first-weekend sales record.[11]

| List of iPhone models |
The hardware design of iPhone 6S is nearly identical to that of iPhone 6, although the chassis is now made of a stronger aluminum first used by theApple Watch Sport to improve its rigidity.[16] It is available in gold, silver, space gray, and new for the 6S, rose gold-color finishes.[17] iPhone 6S is powered by the Apple A9 system on a chip, which the company stated is up to 70% faster than Apple A8, and has up to 90% better graphics performance.[17] iPhone 6S has 2 GB of RAM, more than any previous iPhone,[5] and also supports LTE Advanced.[16] While the capacities of their batteries are slightly lower, Apple rates iPhone 6S and 6S Plus as having the same average battery life as their respective predecessors.[18] Although the device is not promoted as such, the iPhone 6S has a degree of water resistance due to a change to its internal design, which places a silicone seal around components of the logic board to prevent them from being shorted by accidental exposure to water.[19]
Their displays are the same sizes as those of the iPhone 6, coming in 4.7-inch 750p and 5.5-inch 1080p (Plus) sizes. The iPhone 6S features technology known as 3D Touch; sensors are embedded on the screen's backlight layer that measure the firmness of the user's touch input by the distance between it and the glass, allowing the device to distinguish between normal and more forceful touches. 3D Touch is combined with the Taptic Engine vibrator to provide associated haptic feedback.[20] Although it is similar, this is distinct from the Force Touch technology used on the Apple Watch and MacBook, as it is more sensitive and can recognize more levels of touch pressure than Force Touch.[21][22] Due to the hardware needed to implement 3D Touch, the iPhone 6S is heavier than its predecessor.[23]
iPhone 6S features a 12-megapixel rear-facing camera, upgraded from the 8-megapixel unit on previous models, as well as a 5-megapixel front-facing camera. It can also record 4K video, as well as 1080p video at 60 frames per second.[24][25]
Software[edit]
iPhone 6S ships with iOS 9; the operating system leverages the 3D Touch hardware to allow the use of new gestures and commands, including "peeking" at content with a light touch and "popping" it into view by pressing harder,[20]and accessing context menus with links to commonly used functions within apps with harder presses on home screen icons.[20] The camera app's "Retina Flash" feature allows the display's brightness to be used as an impromptu flash on images taken with the front camera, while "Live Photos" captures a short video alongside each photo taken.[16][25]
Reception[edit]
As an S-model iPhone developing on the previous iPhone 6, reviews noted the limited number of changes. However, reviews generally concluded that the phone was improved on its predecessor, although some noted a lack of improvement in battery life. The Verge described the 6S, in particular the Plus model, as "right now the best phone on the market...There just aren't other companies that can roll out a feature like 3D Touch and make it work in a way that suggests the creation of entirely new interface paradigms, and every other phone maker needs to figure out exactly why Apple's cameras are so consistent before they can really compete." It, like several other reviews, described selling a 16GB model as 'ridiculous' and a poor choice for consumers, especially given the large picture file sizes.[26] The Guardiancommented that the phone "has the potential to be the best smaller smartphone on the market, but its short battery life is deeply frustrating" and described the camera as "not leagues ahead of the competition anymore."[27] The Register praised performance, noting that "we’re now using phones with the performance of current PCs," but described force touch as "just a glorified vibrator" and "no good...it's not binary...and you still don’t know quite what’s going to happen until you try."[28] An additional topic noted by journalists around the same time has been the better rate of security updates on iPhones compared to Android phones, with 90 percent of Android phones running insecure and outdated versions.[29]
Issues[edit]
iPhone 6S was affected with following issues:
Overheating of touch ID[edit]
Some users are experiencing the issues of overheating of the touch ID sensor that makes it unusable.[30]
Different processor chips[edit]
There are two different versions of the A9 processor found in the iPhone 6S; a chip made by TSMC and a chip made bySamsung. The Samsung chip supposedly yields worse battery performance than the TSMC chip; this phenomenon is known as 'chipgate'.[31] But multiple independent tests have shown there is no appreciable difference between the two chips.[32]
