iPhone 6s

iPhone 6S and iPhone 6S Plus (stylized and marketed as iPhone 6s and iPhone 6s Plus) are smartphones designed, developed and marketed by Apple Inc. They were announced on September 9, 2015, at the Bill Graham Civic Auditorium in San Francisco by Apple CEO Tim Cook, with pre-orders beginning September 12 and official release on September 25, 2015. The iPhone 6S and 6S Plus were succeeded by the iPhone 7 and iPhone 7 Plus in September 2016.

The iPhone 6S has a similar design to the 6 but updated hardware, including a strengthened chassis and upgraded system-on-chip, a 12-megapixel camera, improved fingerprint recognition sensor, and LTE Advanced support. The iPhone 6S also introduces a new hardware feature known as “3D Touch“, which enables pressure-sensitive touch inputs.

iPhone 6S had a polarized reception. While performance and camera quality were praised by most reviewers, the addition of 3D Touch was liked by one critic for the potential of entirely new interface interactions, but disliked by another critic for not providing users with an expected intuitive response before actually using the feature. The battery life was criticized, and one reviewer asserted that the phone’s camera wasn’t significantly better than the rest of the industry. The iPhone 6S set a new first-weekend sales record, selling 13 million models, up from 10 million for the iPhone 6 in the previous year. However, Apple saw its first-ever quarterly year-over-year decline in iPhone sales in the months after the launch, credited to a saturated smartphone market in Apple’s biggest countries and a lack of iPhone purchases in developing countries.

Hardware

The iPhone 6S is nearly identical in design to the iPhone 6. In response to the “bendgate” design flaws of the previous model, changes were made to improve the durability of the chassis: the 6S was constructed from a stronger, 7000 series aluminum alloy,”key points” in the rear casing were strengthened, and touchscreen Integrated circuits were re-located to the display assembly.Alongside the existing gold, silver, and space gray options, a new rose gold color option was also introduced.

The iPhone 6S 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. The iPhone 6S has 2 GB of RAM, more than any previous iPhone, and also supports LTE Advanced. The Touch ID sensor on the 6S 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 and 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 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, coming in 4.7-inch 750p and 5.5-inch 1080p (Plus) sizes. The iPhone 6S 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 Retina 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 is heavier than its predecessor.

The iPhone 6S 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 and now 120 frames per second.

The iPhone 6S and 6S Plus were originally offered in models with 16, 64, and 128 GB of internal storage. Following the release of iPhone 7 in September 2016, the 16 and 64 GB models were dropped, and replaced by a new 32 GB option. For improved storage performance, iPhone 6S utilizes NVM Express (NVMe), resulting in a maximum average read speed of 1,840 megabytes per second.

Software

The iPhone 6S 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.

iPhone 6

The iPhone 6 and iPhone 6 Plus are smartphones designed and marketed by Apple Inc. The devices are part of the iPhone series and were announced on September 9, 2014, and released on September 19, 2014. The iPhone 6 and iPhone 6 Plus jointly serve as successors to the iPhone 5S and were themselves replaced as flagship devices of the iPhone series by the iPhone 6S and iPhone 6S Plus on September 9, 2015.

The iPhone 6 and iPhone 6 Plus include larger 4.7 and 5.5 inches (120 and 140 mm) displays, a faster processor, upgraded cameras, improved LTE and Wi-Fi connectivity and support for a near field communications-based mobile payments offering.

The iPhone 6 and 6 Plus received positive reviews, with critics regarding their improved design, specifications, camera, and battery life as being improvements over previous iPhone models. However, aspects of the design of iPhone 6 were also panned, including plastic strips on the rear of the device for its antenna that disrupted the otherwise metal exterior, and the screen resolution of the standard-sized iPhone 6 being lower than other devices in its class. Pre-orders of the iPhone 6 and iPhone 6 Plus exceeded four million within its first 24 hours of availability—an Apple record. More than ten million iPhone 6 and iPhone 6 Plus devices were sold in the first three days, another Apple record.

Despite their positive reception, the iPhone 6 and 6 Plus have been the subject of several hardware issues, including most prominently, being susceptible to bending under pressure (a design flaw nicknamed “Bendgate”), and as a byproduct of this lack of rigidity, the touchscreen’s internal hardware being susceptible to losing its connection to the phone’s logic board (nicknamed “Touch Disease”). The iPhone 6 Plus was also the subject of camera issues, including some devices with malfunctioning optical image stabilization or otherwise defects on rear cameras.

The iPhone 6 and iPhone 6 Plus were moved to the midrange spot in Apple’s iPhone lineup when the iPhone 6S and 6S Plus were released in September 2015. The iPhone 6 and 6 Plus were discontinued in most countries on September 7, 2016 when Apple announced the iPhone 7 and iPhone 7 Plus. Their spot as the entry-level iPhone was replaced by the iPhone SE, which was released earlier on March 31, 2016.

Hardware

The design of the iPhone 6 and iPhone 6 Plus are influenced by that of the iPad Air with a glass front that is curved around the edges of the display, and an aluminum rear that contains two plastic strips for the antenna. Both models come in gold, silver, and “space gray” finishes. The iPhone 6 has a thickness of 6.9 millimetres (0.27 in), while the iPhone 6 Plus is 7.1 mm (0.28 in) in thickness; both are thinner than the iPhone 5c and iPhone 5s, with the iPhone 6 being Apple’s thinnest phone to date. The most significant changes to the iPhone 6 and iPhone 6 Plus are its displays; both branded as “Retina HD Display” and “ion-strengthened”, the iPhone 6 display is 4.7 inches in size with a 16:9 resolution of 1334×750 (326 ppi, minus one row of pixels), while the iPhone 6 Plus includes a 5.5-inch 1920×1080 (1080p) display (401 PPI). The displays use a multiple-domain LCD panel, dubbed “dual-domain pixels”; the RGB pixels themselves are skewed in pattern, so that every pixel is seen from a different angle. This technique helps improve the viewing angles of the display.

To accommodate the larger physical size of the iPhone 6 and iPhone 6 Plus, the power button was moved to the side of the phone instead of the top to improve its accessibility. The iPhone 6 features a 6.91 Wh (1810 mAh) battery, while the iPhone 6 Plus features an 11.1 Wh (2915 mAh) battery. Unlike the previous model, the rear-facing camera is not flush with the rear of the device, and has a slight “bulge” around the lens.

Both models include an Apple A8 system-on-chip, and an M8 motion co-processor—an update of the M7 chip from the iPhone 5s. The primary difference between the M8 and the original M7 coprocessor is that the M8 also includes a barometer to measure altitude changes. Phil Schiller touted that the A8 chip would provide, in comparison to the 5s, a 25% increase in CPU performance, a 50% increase in graphics performance, and less heat output. Early hands-on reports suggested that the A8’s GPU performance might indeed break away from previous generations doubling of performance at each yearly release, scoring 21204.26 in Base mark X compared to 20253.80, 10973.36 and 5034.75 on respectively the 5s, 5 and 4s.

The expanded LTE connectivity on the iPhone 6 and iPhone 6 Plus is improved to LTE Advanced, with support for over 20 LTE bands (7 more than the iPhone 5s), for up to 150 Mbit/s download speed, and VoLTE support. Wi-Fi performance has been improved with support for 802.11ac specifications, providing speeds up to 433.0581 Mbit/s—which is up to 3 times faster than 802.11n,[38] along with Wi-Fi Calling support where available. The iPhone 6 and iPhone 6 Plus add support for near-field communications (NFC), which is used exclusively for Apple Pay—a new mobile payments system which will allow users to store their credit cards in Passbook for use with online payments and retail purchases over NFC. NFC support is restricted to Apple Pay only, and cannot be used for any other purposes (such as sharing content with other iPhone users).

The iPhone 6’s rear-facing camera now has the ability to shoot 1080p video at either 30 or 60 frames per second and slow-motion video at either 120 or 240 frames per second. The camera also includes phase detection autofocus. It can also record . The iPhone 6 Plus camera is nearly identical, but also includes optical image stabilization. The front-facing camera was also updated with a new sensor and f/2.2 aperture, along with support for burst and HDR modes.

Software

When first released, the iPhone 6 and iPhone 6 Plus were supplied pre-loaded with iOS 8, while the iPhone 5S was supplied pre-loaded with iOS 7. Apps are able to take advantage of the increased screen size in the iPhone 6 and 6 Plus to display more information on-screen; for example, the Mail app uses a dual-pane layout similar to its iPad version when the device is in landscape mode on the iPhone 6 Plus. As it uses an identical aspect ratio, apps designed for the iPhone 5, iPhone 5C, and 5S can be upscaled for use on the iPhone 6 and 6 Plus. To improve the usability of the devices’ larger screens, an additional “Reachability” gesture was added; double-tapping the Home button will slide the top half of the screen’s contents down to the bottom half of the screen. This function allows users to reach buttons located near the top of the screen, such as a “Back” button in the top-left corner.

iPhone 5

The iPhone 5 is a smartphone that was designed and marketed by Apple Inc. It is the sixth generation of the iPhone, succeeding the iPhone 4S and preceding the iPhone 5S and iPhone 5C. Formally unveiled as part of a press event on September 12, 2012, it was released on September 21, 2012. It was the first iPhone to be completely developed under the guidance of Tim Cook and the last iPhone to be overseen by Steve Jobs.

The iPhone 5 featured major design changes in comparison to its predecessor. These included an aluminum-based body which was thinner and lighter than previous models, a taller screen with a nearly 9:16 aspect ratio, the Apple A6 system-on-chip, LTE support, and Lightning, a new compact dock connector which replaced the 30-pin design used by previous iPhone models. This was the second Apple phone to include its new Sony made 8MP camera, which was first introduced on the iPhone 4S.

Apple began taking pre-orders on September 14, 2012, and over two million were received within 24 hours. Initial demand for the iPhone 5 exceeded the supply available at launch on September 21, 2012, and was described by Apple as “extraordinary”, with pre-orders having sold twenty times faster than its predecessors. While reception to the iPhone 5 was generally positive, consumers and reviewers noted hardware issues, such as an unintended purple hue in photos taken, and the phone’s coating being prone to chipping. Reception was also mixed over Apple’s decision to switch to a different dock connector design, as the change affected iPhone 5’s compatibility with accessories that were otherwise compatible with previous iterations of the line.

The iPhone 5 was officially discontinued by Apple on September 10, 2013 with the announcement of its successors, the iPhone 5S and the iPhone 5C. The iPhone 5 is the shortest lifespan of any iPhone ever produced with only twelve months in production and it is the second iPhone to support five major versions of iOS: 6, 7, 8, 9, and 10 after the iPhone 4S.

Hardware

The iPhone 5 uses a system on chip (SoC), called the Apple A6. The SoC comprises a 1.3 GHz dual-core processor, 1GB of RAM and a tri-core PowerVR SGX543MP4 running at 266 MHz. The iPhone 5‘s operating memory (LPDDR2-1066 eDRAM) was doubled, from 512 MB to 1 GB. Storage capacities available are fixed at 16, 32 or 64 GB, the same as the 4S; plug-in memory cards are not supported. The two color options are black (with black glass and slate-colored metal trim), and white (with white ceramic and silver-colored metal trim); again the same color options (though differently implemented) as its predecessor the 4S had. The iPhone 5 retains the 8 megapixel back camera on the iPhone 4S, but has improved low-light performance, and has a 40% faster photo capture than its predecessors, while having a purple hue when a strong source of light is present in the photograph. The front camera, which is accessible through the FaceTime and camera app has a lower resolution, at 1.2 megapixels. The rechargeable lithium-ion battery with a charge capacity of 1440mAh is built in and cannot be replaced by the user; it is rated at ≤225 hours of standby time and ≤8 hours of talk time. There are three separate models of the phone available: one supporting CDMA and two GSM versions. This can have knock-on effects for which version of the device will actually work in which countries/regions.[citation needed] The phone takes a nano-SIM, smaller than the micro-SIM of the iPhone 4 and iPhone 4S.

Hardware benchmarking conducted using Geekbench and GLBenchmark validates several claims that Apple included on their website and mentioned at the unveiling of the device, these include two times faster and two times the graphics performance. In the Geekbench overall hardware assessment, the iPhone 5 received a score that was approximately 2.5 times higher than the iPhone 4S. The benchmark conducted using GLBenchmark for the iPhone 5 returned a score that was 2 times better than the iPhone 4S. The result was however inconsistent as a 3D graphics benchmark assessment using Passmark returned a score that was only approximately 1.45 times better than the iPhone 4S. Battery life assessments conducted by AnandTech concluded that the battery life is shorter on the iPhone 5 than its predecessor when performing certain tasks, however when performing other tasks the iPhone 5 battery outlasts the iPhone 4S.

The Retina Display is 1,136 × 640 pixels with an aspect ratio of almost exactly 16:9, (minus one extra row of horizontal pixels). With a diagonal of 4″ it has a display size of 6.7 square inches, compared to 5.7 in iPhone 4 and 4S. The pixel density remains the same as the 4S model, which is 326 pixels per inch. Screen icons of the iPhone 5 are arranged in a matrix of six rows of four icons each. The increased screen size allows the sixth row of icons to be added to the five rows that were present in the iPhone 4. In-cell touch sensor technology from Sharp slims the screen which allows for a thinner phone. The screen’s color saturation is 44% greater than its predecessor.

There are three microphones (placed on the front, side and back) for noise cancellation and video calls.

On April 28, 2014, Apple initiated an out of warranty recall program to replace any failing power buttons of iPhone 5 models which were manufactured prior to March 2013 at no cost.

On August 23, 2014, Apple announced a program to replace batteries of iPhone 5 models that “may suddenly experience shorter battery life or need to be charged more frequently” which were sold between September 2012 and January 2013.
