The hardware design of iPhone 6S plus is nearly identical to the iPhone 6, although the chassis is now made of a stronger aluminum to improve its rigidity.It is available in gold, silver, space gray, and new for the 6S plus , rose gold-color finishes.iPhone 6S plus is powered by the Apple A9 system-on-chip, which the company stated is up to 70% faster than Apple A8, and has up to 90% better graphics performance. iPhone 6S plus has 2 GB of RAM, more than any previous iPhone, [6] plus and also supports LTE Advanced.The Touch ID sensor on the 6S plus was also updated, with the new version having improved fingerprint scanning performance over the previous version.
While the capacities of their batteries are slightly smaller, Apple rates iPhone 6S Plus as having the same average battery life as their respective predecessors.The A9 system-on-chip was dual-sourced from TSMC and Samsung. Although it was speculated that the Samsung version had worse battery performance than the TSMC version, multiple independent tests have shown there is no appreciable difference between the two chips.Although the device is not promoted as such, the iPhone 6S plus has a degree of water resistance because of 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.
Their displays are the same sizes as those of the iPhone 6 plus coming in 5.5-inch 1080p . The iPhone 6S plus features a technology known as 3D Touch; sensors are embedded in the screen’s backlight layer that measure the firmness of the user’s touch input by the distance between it and the cover glass, allowing the device to distinguish between normal and more forceful presses. 3D Touch is combined with a Taptic Engine vibrator to provide associated haptic feedback.Although 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.Due to the hardware needed to implement 3D Touch, the iPhone 6S plus is heavier than its predecessor.
iPhone 6S plus features a 12-megapixel rear-facing camera, an upgrade from the 8-megapixel unit on previous models, as well as a 5-megapixel front-facing camera. It can record 4K video, as well as 1080p video at 60 frames per second.
Another significant upgrade to iPhone 6S Plus over predecessor models is the use of NVMe to interface with their flash controller which drives some SK Hynix TLC NAND flash memory, resulting in a maximum read speed of 1, 840 megabytes per second.
Software Edit
iPhone 6S plus ships with iOS 9; the operating system leverages the 3D Touch hardware to allow recognition of new gestures and commands, including "peeking" at content with a light touch and "popping" it into view by pressing harder, and accessing context menus with links to commonly used functions within apps with harder presses on home screen icons.The camera app’s "Retina Flash" feature allows the display’s brightness to be used as a makeshift flash on images taken with the front camera, while "Live Photos" captures a short video alongside each photo taken.
As an S-model iPhone developing on the previous iPhone 6 plus , 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 plus , 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.The Guardian commented 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."
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."AnandTech awarded the iPhone 6s its second ever Editor’s Choice Gold Award for a phone based largely on the phone’s performance and the addition of 3D Touch.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.
