IPhone 4s

Template:Infobox iPhone

The iPhone 4S is a touchscreen slate smartphone developed by Apple. It is the fifth generation of the iPhone, a device that combines a widescreen iPod with touchscreen, mobile phone, and internet communicator. It retains the exterior design of its predecessor, iPhone 4, but is host to a range of improved hardware specifications and software updates compared to the previous model. Integrated software and hardware changes support the introduction of new user interface and functions by Apple. Highlights include a voice recognizing and talking assistant called Siri, personal computer independence, cloud-sourced data (iCloud) and an improved camera system. A selection of the device's functions can be controlled by voice.

The iPhone 4S was unveiled at Apple's Let's Talk iPhone event on October 4, 2011 in Cupertino, California. Apple started taking pre-orders for the iPhone 4S on October 7, 2011 in seven initial countries — United States, Canada, Australia, United Kingdom, France, Germany, and Japan — with a first delivery date set for October 14, 2011, and available on that same day for direct store sales in those countries. It will be released in 22 more European, American and Asian countries, including Ireland, Mexico and Singapore on October 28.

It will be available on 100 carriers in 70 countries overall, including AT&T, Verizon, and for the first time, also for Sprint customers in the United States. In Japan it will be available for au (a KDDI brand) and Okinawa Cellular, for the first time.

For U.S. customers, while pre-orders for purchasers buying contracts started on October 7, 2011, unlocked (contract-free) sales are expected to begin in November 2011. AP says that AT&T described early iPhone 4S demand as "extraordinary".

History

Announcement

For some, a series of expectations about Apple's next generation phone including various specifications and a predicted name—"iPhone 5"— were built up in the time preceding its debut. After the iPhone 4S was announced, there was some disappointment about this. However, as early as May 2011 some leaks had a fairly accurate description of the product including the name "iPhone 4S", the A5 chip, HSPA+, new/better camera, and Sprint carrying. As it turn out, there was no major or minor external differences between the iPhone 4 and iPhone 4S, the changes were inside. Nevertheless, it has still been described as a "dramatic leap forward in technological innovation and sophistication...". The keynote was the first in which Tim Cook led since the Verizon keynote earlier that year. It was their first product launch however, and they had to do while their longtime friend and leader Steve Jobs' health was deteriorating. Many praised Cook for focusing on company achievements while others criticized him for this. One unique aspect was that the whole management team of several people took turns discussing the new products. The next day after release one of Apple's founders, Steve Jobs passed away, who had just stepped down as CEO a month previously due to health issues.

Reception

The initial reception to the iPhone 4S was very favorable with many users being impressed with its Siri voice recognition and dictation software. However, with no drastic changes and few new features apparent, the unveiling of iPhone 4S failed to impress some critics. Many are not disappointed, as the iPhone 4S is a similar update to the iPhone 3GS, where there is no design changes, but there are definitely changes on the inside of the iPhone. Vincent Nguyen of SlashGear described the iPhone 4S as "wickedly fast, fiendishly well equipped and ruthlessly threatening to its mobile rivals".

Reuters suggests this could open new market opportunities for rivals. Shares of Samsung Electronics, HTC and Nokia gained on Wednesday after the 4S was announced, while Apple stock dipped sharply. However, later in the day Apple shares rebounded, ending at a 1% gain. Analyst C. K. Lu of Gartner believes that Apple no longer has the leading edge and 4S will only sell due to brand loyalty, as fans were expecting an iPhone 5 with a thinner profile, bigger screen, and stronger features. Some of these same people also wanted a cheaper stripped down iPhone 4.

The German phone company Deutsche Telekom said they were "satisfied" with consumer interest.

With the launch of the pre-order, AT&T said that the demand for the iPhone 4S was "extraordinary". Over 200,000 pre-orders were placed within 12 hours through AT&T. In addition, AT&T, Verizon, and Sprint sold out of pre-order stock by October 8th, 2011 and by the 9th there was a 1-2 week estimate on new pre-orders to be filled.

On October 10th, Apple announced that over one million iPhone 4Ss had been pre-ordered within the first 24 hours of it being on sale, beating the 600,000 device record set by the iPhone 4. It is believed that Steve Jobs' death helped in drastically increasing the pre-orders of the iPhone 4S, as it is the last Apple product in which he had a hand in developing. The 16-month wait between the iPhone 4 and the iPhone 4S may have contributed to overwhelming sales as well.

By October 11th, early reviews of the iPhone 4S were released. Reviewers noted the software voice assistant, camera system, and processing speeds.

Retrevo surveyed more than 1,300 U.S. consumers and reported that 71 percent of all smartphone owners were not disappointed by the new iPhone 4S but 47 percent or almost a half of current iPhone 4 owners were. 12 percent were hoping for a bigger display, 21 percent wanted a refreshed design, and 29 percent desired 4G.

Unlike previous iPhone models, the sales of the iPhone 4 had not climaxed prior to the 4S introduction. For example, the 3G model came out when sales of the first iPhone had declined to less than half their peak. In addition, iPhone 4 users had high marks for being satisfied with their phone. Nevertheless, they wanted even more from Apple, but forgot that from Apple's perspective the iPhone 4 was still a hit and that new users may not be bothered by the look and feel staying the same, because they did not have iPhone 4 in the first place.

Design

The iPhone 4S is primarily a combination of a hand-held computer, cell-phone, GPS, digital/video camera, and music player into one device, powered by a rechargeable lithium-ion battery. It is supported by an online infrastructure where media and secondary applications can be acquired to run on the device, thereby expanding its capabilities.

The iPhone 4S retains almost all of the same design features as its predecessor, the iPhone 4. The front and back are both flat, the screen being made of glass. There is a camera on the back and the sides are stainless steel with metal buttons. It keeps the 3.5 inch (8.89 cm) screen of past iPhones with the "home" button at the bottom. The iPhone 4S comes in two colors, black and white.

Hardware

Comparison between iPhone 4 hardware (top) and iPhone 4S hardware (bottom). Notice the repositioned antennae, which is most likely due to antenna issues with the iPhone 4.

Antenna

Improving on the external stainless steel, dual-antenna design of its predecessor, the iPhone 4, Apple has redesigned the antenna in the iPhone 4S so that the cellular radio in the phone can choose between two antennas, depending on which is sending or receiving signal best. These two antennas are part of the stainless steel band that wraps around the sides of the iPhone 4 and the iPhone 4S.

The bands on the iPhone 4 are divided into four antennas, cellular, Bluetooth, GPS, and Wi-Fi, while the iPhone 4S, in addition to the iPhone 4, has the cellular (GSM) antenna divided into two pieces. Therefore, if the iPhone 4S is gripped in such a way as to attenuate one piece of the cellular antenna, the radio will switch to the other piece that isn’t being gripped.

The iPhone 4S is theoretically capable of supporting a maximum throughput of up to 14.4 Mbps with HSDPA as a result of an upgraded radio chip inside the phone, in addition to being a world phone, so both CDMA and GSM customers can now roam internationally on GSM networks. It also supports Bluetooth 4.0.

Camera

The camera on the iPhone 4S is capable of shooting 8MP stills (3264 by 2448 pixels) and recording 1080p videos at thirty frames per second with upgraded quality (30% better clarity, 26% better white balance, color accuracy) thanks to additional lens, IR filter and Image signal processor (built-in A5) The camera can now be accessed directly from the lock screen, and the volume up button as a shutter trigger. The built-in gyroscope is able to stabilize the camera while recording video. Other features of the camera are macro (for close up pictures) and faster capture including being able to take its first picture in 1.1 seconds and the next half a second later..

Input and output (I/O)

Users can input commands with a touch screen that can be touched in more than one place at once, multi-touch. They can also talk to the device—and it can talk back. The device will attempt to do what the user says, such as send text messages or look for nearby restaurants. It also has several traditional buttons, including one on the front and some on the side, such as volume buttons. Human output includes a small speaker, vibration, and a color display which is 3.5 inches across diagonally with 960 by 640 pixels. The speaker is used for media, phone conversations, and lets the digital assistant talk back. Another output is the LED flash for the camera.

The iPhone 4S supports video out via AirPlay and various Apple A/V cables. Supported video formats include such formats as H.264 (1080p 30 fps max.), MPEG-4 video, and motion JPEG (M-JPEG).

In addition to user inputs the device also has several other sensors, such as a 3-axis gyroscope that allows it to detect its orientation.

Power and battery

The iPhone 4S is stated to have 200 hours standby time (iPhone 4 300 hours), 8 hours talk time on 3G (iPhone 4 7 hours), 14 hours talk time on 2G, 6 hours 3G browsing, and 9 hours Wi-Fi browsing. The time of use depends on power from the lithium-ion battery inside the device. It can be recharged by power from a USB port or power adapter. The battery is enclosed inside the device, and as other Apple devices, is not designed to be removed except for completely new battery replacements by experienced technicians.

Processor, memory, and storage

Further information: Apple A5

The iPhone 4S has a dual-core Apple A5 processor, compared to the single core Apple A4 processor used in the iPhone 4. It has 512 MB of RAM, the same as its predecessor. Maximum available storage size increased to 64 GB whilst the 32 GB and 16 GB model options were retained. The screen is the same as the previous generation's iPhones; 3.5 in, 640×960 resolution (Apple's "retina" design). The improvement in interactive multimedia applications was obvious compared to its predecessor. However, applications that take more advantage of the new specs will take time to be developed and released. In one early review it scored 677 in a "Geekbench" benchmark speedtest compared to 370 for the iPhone 4, and in that test higher is better.

Features

Gaming

See also: Game Center

The iPhone 4S uses the Apple A5 system-on-a-chip that uses an Imagination Technologies PowerVR SGX graphics processing unit, which features pixel, vertex, and geometry shader hardware, supporting OpenGL ES 2.0 and DirectX 10.1 Shader Model 4.1. The SGX is the same GPU used in the iPhone 4S’ predecessor, the iPhone 4. However, the iPhone 4S uses a dual-core model, the SGX543, that is integrated with the Apple A5 SoC in the same way as the iPad 2.

Apple’s claim that the iPhone 4S can process graphics up to “seven times faster” than the iPhone 4 was corroborated by Epic Games President Mike Capps. At the “Let’s Talk iPhone” event held by Apple on October 4, 2011, Capps demonstrated Epic Games’ Infinity Blade 2, the sequel to Infinity Blade, on an iPhone 4S. Capps boasted that the game uses Epic Games’ Unreal Engine 3 and features the same graphic techniques used in the Xbox 360 game Gears of War 3.

Gaming on the iPhone 4S has been likened to the PlayStation Vita, that features the same SGX GPU only in a quad-core configuration, and the Nintendo 3DS handheld game consoles. Additionally, the iPhone 4S’ ability to process 35 million polygons per second has been compared to the PlayStation 3 and the Xbox 360 home video game consoles that are capable of processing 275 million and 500 million polygons per second respectively.

CVG’s deputy editor Andy Robinson told TechRadar that the “[iPhone 4S] is certainly laying down some serious credibility for the iPhone as a core gaming device. Not only is it now pushing out games that simply eclipse the [Nintendo 3DS] visually, but features like cloud saving and TV streaming support are really exciting for gamers.”

Senior Gaming Analyst at Jon Peddie Research Ted Pollak believes the biggest improvement to gaming on the iPhone 4S is the voice control features, noting that “one of the features that Nintendogs players loved was the ability to talk to it. There’s no reason why a game like that couldn’t be done on the iPhone 4S, and much more sophisticated given the voice control shown.”

Siri

The iPhone 4S introduced a new automated voice control system called "Siri", unique to the 4S, that allows the user to give the iPhone commands, which it can execute and respond to. For example, iPhone commands such as "What is the weather going to be like?" will generate a response such as "The weather is to be cloudy and rainy and drop to 54 degrees today". These commands can vary greatly and control almost every section of the phone. The commands given do not have to be specific and can be used with natural language. Siri can be accessed by holding down the home button for an extra amount of time (compared to using the regular function). An impact of Siri, as pointed out by Apple video messages, is that it is much easier and/or possible for people to use device functions while driving, exercising, or when they have their hands full. It also means people with trouble reading, seeing, or typing can access the phone more easily.

Its not clear what the impact of Siri speaking in public will be, but it does not have to speak out loud and can be used with headphones.One interface feature of Siri is that it can be activated by holding the phone to a person's head. The iPhone 4S has a proximity sensor.

At launch Siri supports French, English, and German languages. In one early review, German Siri handled the language well but needed more information from supporting databases, such as route information and possibly the Wolfram Alpha "Computational Knowledge Engine". One early review noted its good performance in English, although it did confuse "4" and "for" at one point. The New York Times said Siri's ability to comprehend was "mind-blowing".

The Harvard Business School described Siri as the new phone's most interesting feature, and how well it works could make or break it.

Apple says the A5 is a reason why Siri may not come to other devices even with iOS 5 upgrades. However, some gadget reviewers believes otherwise. Several smartphone reviewing sites have pointed out that Apple is making Siri exclusive to the iPhone 4S because that is the only selling point of the phone compared to the previous iPhone 4.

Siri is supported by the A5 chip and currently an iPhone 4S exclusive. Siri also needs internet access to function. When used for the first time, Siri does not require setup but does adapt to a user's voice over time, and can also be taught certain things directly. A number of aspects of the software can be configured, such as language and its voice feedback ability (its ability to talk back).

At launch Apple said Siri is still in Beta, and it has a certain set of abilities with restrictions, such as being able to dictate texts but not emails, and only controlling certain apps. Nevertheless one area it may be useful is driving and exercise activities. It is integrated with Apple's Find My Friends program (which debuted at the same time as the 4S), so so Siri can potentially answer questions like "Where is my wife?". When it is enabled, Apple's Find My Friends lets a social group know where each other are and Siri can use this information to answer questions. Siri can be taught information, so it knows who a person is referring to when they use generic terminology on that device.

Messaging

Main article: iMessage

On the iPhone 4S, texting can be done aided by the voice assistant which allows speech-to-text. In addition to regular texting, messaging on the iPhone 4S is supported by iMessage, a specialized instant messaging program and service that allows unlimited texting to other Apple iOS 5 products. This supports the inclusion of media in text messages, integration with the device's voice controlled software assistant, and read receipts for sent messages. iMessages are in blue, and regular texts in green in the screen bubbles. Input to the computer comes from a keyboard displayed on the multi-touch screen or by voice-to text by speaking into the microphone. Entered text is supported by predictive and suggestion software as well as a spell checker, that includes many regional dialects like Swiss spoken French.

Since Siri can send text messages, a person can text and drive without taking their eyes off the road, as shown in Apple's video ad. Another example, is that a person can ask Siri for information while they are cooking and their hands are messy. It also makes it much easier for people with physical disabilities such as blindness to compose and send text messages.

Language

At announcement plans were in place for the iPhone 4S to support many languages of the World. Different features have different language requirements, such as keyboards compared to the word predictor and spell-checker, which needs a large dictionary of words. Language support is related to the iOS 5 operating system that the device launched with, although not always. The Siri digital assistant supported French, English, and German at launch. Since it uses a software based keyboard supported by the multi-touch display, it can support many different keyboard layouts without having to change physically. The iPhone 4S can display different languages and scripts at the same time.

Network

The device is a World phone and can work on both GSM & CDMA networks. On a 2G (on GSM) network it supports up to 14 hours of talk time. It can download at maximum rate of 14.4 Mbps on a HSPA+ network such as AT&T Mobility's. On CDMA networks however it is limited to 3.1 Mbps, this includes Verizon Wireless's.

Operating system

Main article: iOS

iPhone 4S was announced with Apple’s iOS 5 operating system, which Apple claims as having 200 new features compared to the previous version. On the 4S, the Apple A5 processor and iOS 5 work together to support many subsystems of the device, such as data processing for the camera. Some major tasks performed include browsing the internet with Safari, voice assistance with Siri, cellular communications, media playback, and applications.

It supports PC and Mac freedom, where updates can be downloaded by over-the-air to the device. Another feature is the ability to have Apple send a real card in the mail with the Apple Cards application.

Accessories

Bumper

An iPhone 4/iPhone 4S Bumper is a ring of rubber and plastic that surrounds the edge of the iPhone 4S. The inner part is synthetic rubber with the external band made of plastic. A Bumper wraps around the edges of the device protecting the edges, and to a lesser extent, the screen. The Bumper does not cover the front or rear of the phone, though it does slightly raise it off whatever surface it is placed upon. Additionally, the plastic band houses metallic buttons for the volume controls and sleep/wake button. The six holes in the Bumper enable access to the mute switch, dock connector, headphone jack, speaker, and microphones. Bumpers are available in six colors: black, blue, green, orange, pink, and white.

Since the iPhone 4S has the same design and subsequent dimensions as the iPhone 4, most bumpers fit both the iPhone 4 and iPhone 4S.

Availability

The Apple iPhone 4S is planning to launch with 100 carriers in 70 countries in the closing months of 2011.

The device is typically sold to consumers with an initial fee and a two year contract, whereby a person will agree to pay a certain amount upfront then each month pay an additional fee for the time of the agreement. This also pays for using some services, mainly the wireless data transmission to cell phone towers. Depending on the contract, additional services may require more fees or be included. The business that sells the devices offer different types of contracts to people, and may charge different amounts per month. From the standpoint of the business, they subsidize the initial cost of the phone to make it more appealing, eventually recouping the money during a payback period.

United States

As with the iPhone 4 in the U.S., starting on October 14th 2011, the iPhone 4S was available on Verizon and AT&T. In addition, the iPhone 4S was be offered by Sprint, a new carrier for Apple. This confirms a Wall Street Journal report, that the American telecommunications company Sprint Nextel committed $20 billion to do this. All 3 carriers require a new 2-year contract with the phone, in addition to the purchase price of the device. Sprint was the third largest cell-phone carrier in the United States at that time.

In addition to being sold by AT&T, Verizon, and Sprint, Apple will sell an unlocked version of the iPhone 4S. The phone includes no micro-SIM card and will not work on CDMA Carriers.

Apple is also allowing the iPhone 4S to be sold directly to people without a contract in November 2011, they will work on GSM but not CDMA networks with service from a provider. Unlocked or contract-free phones support micro-SIM cards from networks. The card is a small memory device that plugs into the phone in a small slot/tray, and contains the information for the device to run on that cellular network. Non-contract phones need to gain access to a cellular network service to be used that way.

Apple listed prices for a contract free phone in the United States are $649 for the 16GB model, $749 for 32GB, and $849 for the 64GB. Compare to $199 (16GB), $299 (32GB), and $399 (64GB), with a 2 year contract. If the cost per month is for example 130 dollars for unlimited voice and text, that works out to about $3120 ($130 times 24 months) not counting other costs or discounts. Each carrier can offer different advantages, for example, the New York Times says the only U.S. carrier with an unlimited data plan at the 4S launch was Sprint, Verizon has the best coverage, and AT&T has the best speeds.

Canada

In Canada the iPhone 4S will be offered by all the major networks including Rogers Wireless, Bell Mobility, Virgin Mobile Canada, and Telus Mobility.

Asia/Pacific

In Australia all three of the countries major networks have announced that they will carry the handset, with pricing from Vodafone Australia and Optus already announced. Telstra has opened a registration page found on their website, yet pricing has not been announced. Contract-free/Unlocked models will be available from Apple Retail Stores on launch day, Friday 14 October 2011.

In Japan, au by KDDI will join SoftBank Mobile, previously the sole Japanese carrier of the iPhone, in selling the 4S model. Softbank plans to charge ¥4,410 ($57) a month.

Europe

In the U.K., the iPhone 4S will be available on major carriers O2, Orange, T-Mobile, Three, Tesco Mobile, and Vodafone. It will also be sold SIM-free and in all variants via Apple’s online store and retail stores at a fixed price without a contract.

Some Germans got their iPhone 4S pre-orders delivered as early as October 11th, rather then 14th. This was the first deliveries of millions pre-orders and provided some early independent reviews.

Impact

According the the Harvard Business School, devices similar to the iPhone 4S are the Motorola Bionic and Samsung Galaxy.

Used-phone market

The used phone market saw unprecedented rates of trade-ins in the weeks leading up to the 4S announcement, and after it there was a drop in prices offered. There are many third-party buyers of old phones, and Apple also buys back old phones under a special program.

Names

A day after the announcement of iPhone 4S, Apple's founder Steve Jobs passed away, and there are some online and media speculations that the designation "4S" stands for "For Steve". Many other sources say that the 'S' in the name stands for 'speed', as some speculated was the case with the iPhone 3GS. The names "Siri" and "shutter" (referring to the highly upgraded camera) have been speculated to also stand for the "S" in the name.
