The iPad 2 is a tablet designed, developed and marketed by Apple Inc. Compared to the first iPad, as the second model in the iPad line, it gained a faster dual core A5 processor, a lighter build structure, and was the kickoff iPad to feature VGA front-facing and 720p rear-facing cameras designed for FaceTime video calling.

The device was available initially with three storage sizes – 16, 32, and 64 GB[8] [3] – and two varying connectivity options – Wi-Fi only or Wi-Fi and cellular. Each variation of the device is bachelor with either a black or white front drinking glass panel. Yet, upon the release of the 3rd generation iPad in March 2012, just the sixteen GB variation remained available.

The production became bachelor in March through May 2011.

The device received generally positive reception from various blogs and publications. Although it was praised for its hardware improvement, such every bit the new Apple tree A5 chip, the software restriction on the iPad 2 and iOS in full general drew criticism from various technology commentators.[9] [10] The device sold well in its kickoff month of sales with 2.4–two.six million units sold and xi.12 million units were sold in the 3rd quarter of 2011.[eleven] [12]

A popular product, with a lower screen resolution and operation than the two Retina models that followed it but a lighter build and longer bombardment life, information technology remained in the Apple line-upwards as an entry-level iPad model for three years until March 2014, latterly with a silent upgrade to a dice-shrunk version of the A5 processor. Its basic design formed the core of the first iPad mini, which had the aforementioned screen pixel count and similar features at a smaller size.

Originally shipped with iOS iv, with the release of iOS ix the iPad 2 became the only device to take received six major versions of iOS. It kept that distinction until iOS 12 was released for the iPhone 5S, iPad Air and iPad Mini 2. This would later be surpassed by the iPad Air 2, receiving 7 from iOS 8 to iPadOS xv.

History [edit]

Apple sent invitations to journalists on February 23, 2011, for a media outcome on March ii.[xiii] [14] On March 2, 2011, CEO Steve Jobs unveiled the device at the Yerba Buena Middle for the Arts, despite being on medical leave.[15] Upon the proclamation of the iPad two, the original iPad was discontinued from sales online and at Apple authorized retail stores.[16]

Apple began selling the iPad ii on its website on March 11,[17] and in its U.S. retail stores at 5 pm local time on that date. Many stores in major cities, such as New York, sold out within hours.[18] Online aircraft delays had increased to three to four weeks on Sunday and four to v weeks by Tuesday.[xix] [20]

The iPad 2 was released internationally in 25 other countries on March 25, 2011. The countries included Australia, Austria, Kingdom of belgium, Canada, Czech republic, Denmark, Republic of finland, France, Germany, Greece, Iceland, Italy, Republic of ireland, Republic of hungary, Luxembourg, Mexico, Netherlands, New Zealand, Norway, Poland, Portugal, Espana, Sweden, Switzerland and the United Kingdom.[21]

The April 29, 2011 release date for Nippon was postponed due to the earthquake and tsunami which struck the nation on March xi, 2011. The iPads were delayed due to the NAND flash storage fleck used in the iPads beingness created by Toshiba, which was afflicted past the earthquake and seismic sea wave thus resulting in the suspension of operations for an indefinite period of time.[22] The slowdown acquired analysts to downgrade Apple's stock.[23]

The iPad two was later released in Hong Kong, India, Southward Korea, Singapore, Philippines, Malaysia and other countries including Japan on April 29, 2011.[24] It was then released in numerous other nations which include Red china, Estonia, Thailand, Brazil, Russia and Taiwan on two major release dates, May 6 and 27.[25] [26]

The 32 and 64GB models were discontinued on March vii, 2012, upon the introduction of the tertiary generation iPad. The 16GB Wi-Fi and 16GB Wi-Fi + 3G models were discontinued on March xviii, 2014.[27]

Features [edit]

Software [edit]

In tardily March 2011, the iPad ii was released alongside iOS 4.3,[28] [29] which primarily introduced Airplay Mirroring and Home Sharing among other features.[30] On October 12, 2011, upon the release of the iPhone 4S, the iPad was upgradable to the iOS 5 firmware update which brought over 200 new user features to iOS compatible devices including Notification Middle, iMessage, Reminders, and an updated notifications organization, using a new "banner" mode instead of the previously used pop-up "alert" style.[31]

The iPad ii comes with several applications past default, including Safari, Mail, Photos, Video, Music, iTunes (store), Maps, Notes, Calendar, Photo Booth, and Contacts.[32] The App Store is besides available every bit a default application, it enables users to download from a database of 800,000 applications,[33] the price of these applications is fix by the developers. Like all iOS devices, the iPad ii can sync music, videos, apps and photos with a Mac or PC using iTunes, although when using iOS five and later, the user does not take to connect the iPad to the computer.[34] iCloud besides allows users to backup and sync their data with other compatible iOS devices via the net. Game Center is available as a native social gaming platform on iOS, games downloaded via the App Store that have this feature enabled are able to integrate their achievement points, high-scores and bonus system beyond all iOS devices into a unmarried accumulative points and social platform.[35] Although the tablet is non designed to make phone calls over a cellular network, a user can use a wired headset or the built-in speaker and microphone and place phone calls over Wi-Fi or cellular using a VoIP application.[36]

The iPad two also adds the ability to run GarageBand, iMovie, and the iWork apps Pages, Keynote, and Numbers.[37] These applications do not come up with the iPad but are instead official applications from Apple sold inside the App Shop. On March vii, 2012, later on the unveiling of the third generation iPad, the firmware of the iPad 2 was upgradable to iOS 5.1.[38] Scott Rohde, a senior Sony executive described the iPad as "a game console bearded every bit a device that tin be appropriated in the business concern workplace."[39]

On September xix, 2012, almost a week after the announcement of the iPhone 5, iOS 6 was released for numerous iOS devices, including the iPad two and iPhone 4S.[40] However, on iOS six, not all features are available on the iPad ii. The software upgrade was downloadable every bit an over the air (OTA) update package and contains two hundred new features, including a mapping software designed past Apple tree dubbed Apple Maps, a "Clock" app, which features a timer, stopwatch and alert, and Facebook integration among other new features and tweaks.[40]

The iPad 2 is uniform with iOS 7, which was released on September 18, 2013.[41] Nonetheless, some features are not available. For example, similar the iPhone 4, the Notification Centre and the Control Center employ the transparent way instead of the translucent style in afterward iOS models. Also, AirDrop, which was outset released in iOS 7, was just supported past the iPad 4 or later.

The iPad 2 can run iOS 8, which was released on September 17, 2014, making it the first iOS device to run five major versions of iOS (including iOS iv, 5, six, seven, and 8).[42] While the OS runs on the device, nearly of its new features do not work because of relatively aged hardware and therefore, its functioning is limited. Users have also reported numerous issues later receiving the update including the accessibility features and battery-related issues. Many users speculated that the iPad two was going to be dropped from updating to iOS eight forth with the iPhone iv, the aforementioned process that happened with the iPhone 3GS and the iPod Touch (fourth generation) and earlier models, considering that the model was more iii years old.

It was confirmed on June 8, 2015, at Apple's WWDC that the iPad ii would run iOS 9, making it the first iOS device to run six major versions of iOS. As with previous releases, though, many headline features were unavailable on the iPad 2, including predictive Siri, translucency effects, split-view, slide-over and picture-in-picture multitasking and the Health app.[43] [44] iOS 9 is said to characteristic performance improvements that may help the aging device function more smoothly, and initial tests propose that information technology did not significantly impact available space. Other A5-based devices volition also run iOS nine including the iPhone 4S (five major iOS versions), the iPad Mini (four major iOS versions) and iPod Bear on 5G (4 major iOS versions).

On June 13, 2016, with the release of iOS x, Apple dropped support for the iPad two because of its hardware and functioning issues. The aforementioned goes with its successor and the iPad Mini (1st generation), making iOS 9.iii.v (Wi-Fi) or iOS 9.3.6 (Wi-Fi + Cellular) the final version that will run on the device.[45]

"Broadpwn" exploit vulnerability [edit]

The iPad 2 is one of many computers and mobile devices susceptible to the "Broadpwn" exploit, which was publicized in July 2017.[46] Apple quickly released an update for iOS 10 to fix the problem, simply a fix was never released for iOS 9 or before versions of iOS. As a result, older Apple tree devices incompatible with iOS 10, including the iPad 2, were left vulnerable indefinitely. This has raised concerns of potentially widespread attacks using the exploit, particularly in locations of concentrated iPad two deployment, such equally certain main and secondary schools.[47]

2019 GPS rollover update [edit]

On July 22, 2019, Apple released iOS 9.3.6 for the CDMA model of the iPad 2 to fix issues caused by the GPS week number rollover. The bug would impact accuracy of GPS location and set the device'due south appointment and time to an wrong value,[48] preventing connexion to HTTPS servers and, consequently, Apple'south servers for activation, iCloud and the iTunes and App stores. The WiFi model and the GSM model are not afflicted by the rollover as the WiFi model lacks a GPS chipset and the GSM model uses a different chipset.

Hardware [edit]

Apple tree A5 chip used in the iPad two

The iPad 2 features an Apple A5 bundle-on-package (Pop) System-on-fleck (SoC), which comprises a i GHz dual-core 32-bit Cortex-A9 CPU, 512 MB of RAM and a dual-core PowerVR SGX543MP2 GPU.[3] [49] Other features include forepart and rear cameras, a three-axis gyroscope, headset controls, proximity and ambient light sensors, microphone, magnetometer, accelerometer and a 9.seven inch multi-affect screen with a maximum resolution of 1024×768 hence resulting in 132 ppi.[iii] The iPad two has four concrete switches, including a home button near the brandish that returns the user to the dwelling screen, and three plastic concrete switches on the sides: wake/sleep, volume up/down, and a third switch for either screen rotation lock or mute. The home button on the iPad two is "easier to double tap" than the previous generation of the iPad.[fifty] Apple reduced the size of the iPad past eliminating the stamped sheet metal frame from the brandish, integrating new thinner glass technology for the touch screen overlay, and slightly reducing the space betwixt the display and battery.[51] The iPad 2's screen is thinner, lighter, and all the same stronger than the original iPad's.[52] The iPad ii also supports screen mirroring via the digital AV adapter[53] and through AirPlay equally of iOS 5.

The iPad 2 has a 25 W·h rechargeable lithium-ion polymer battery[3] that lasts 10 hours, like the original iPad. Information technology is charged via USB or included 10 W, two A power adapter. The bombardment is 2.five mm thick, 59% smaller than the original and has three cells instead of 2. The improvements allowed the injection-molded plastic support frame to be omitted.[51] The 10 Westward USB power adapter provides 4x the power of a conventional USB port.[iii] The tablet has an audio frequency response of 20 Hz to 20 kHz. Without third-political party software it tin play the following audio formats: HE-AAC, AAC, Protected AAC, MP3, MP3 VBR, Aural formats (2, 3, 4, AEA, AAX, and AAX+), ALAC, AIFF, and WAV.[3]

The revised tablet adds front- and rear-facing cameras, which allow FaceTime video calls with other iPad 2s, the third generation iPad, iPhone 4 and 4S, fourth-generation iPod Impact and Macintosh computers (running Mac OS X ten.6.half dozen or afterward with a webcam).[54] The 0.iii MP front camera shoots VGA-quality 30 frame/s video and VGA-quality however photos.[3] The 0.vii MP back camera tin shoot 720p HD video at thirty frame/s and has a 5× times digital zoom.[6] Both shoot photo in a 4:3 fullscreen aspect ratio. The rear photographic camera shoots video in 16:9 widescreen to friction match the 720p standard, although simply the cardinal 4:3 part of the recording is shown on the screen during recording.[nine] The forward-facing camera shoots in 4:3.[55]

The Apple A5 chip doubles processing speed and has graphics processing that is up to nine times faster than the previous iPad.[56] [57] However, benchtests and hardware assessments performed by various third political party news sources and technology blogs point that those claims are exaggerated; the benchmark assessment conducted by Anandtech showed that the GPU of the iPad 2 is merely iii times faster than that of the original iPad.[58] CPU benchmarks conducted on the iPad 2 by iOSnoops indicate a 66% functioning increase compared to the original iPad.[59] [60]

3G versions of the iPad ii offer CDMA2000 back up for customers using the device on a CDMA network or GSM/UMTS back up for customers using the device on a GSM/UMTS network. The iPad Wi-Fi + 3G model includes an A-GPS receiver for tracking the user's location given permission. Also, the iPad 2 3G model includes a plastic cap-like band at the top on the dorsum for the 3G antenna. The metallic grille for the microphone is replaced with a matching plastic black grille on the 3G model.[61] GSM models of iPad 2 use a SIM bill of fare while CDMA models employ an ESN to connect to the cellular network.

The device is 15% lighter and 33% thinner than the original iPad; information technology is thinner than the iPhone iv past 0.five mm.[62] The Wi-Fi version is i.33 lb (600 g). Both the GSM and CDMA versions (known respectively as the AT&T and Verizon versions in the Usa) differ in weight slightly due to the mass departure between the GSM and CDMA cellular radios, with the GSM model at 1.35 lb (612 m) and the CDMA model at i.34 lb (608 grand). The size of the iPad 2 is also less than the original iPad at simply 9.50 in ×7.31 in ×0.34 in (241.two mm ×185.7 mm ×8.8 mm),[three] compared to the original iPad's size at nine.56 in ×7.47 in ×0.5 in (242.8 mm ×189. mm 7×13.iv mm).[63]

After the announcement and release of the third generation iPad, the iPad 2, which continued to be available for buy, received a hardware upgrade. The upgraded variant of the iPad 2 features a smaller version of the Apple A5 SoC, which is able to reduce bombardment consumption.[64] Benchmark tests conducted by Anandtech concluded that the upgraded variant is able to final longer by at least an hour and a half, depending on the job that is conducted on the device.[64] The maximum temperature that the device heated up to was as well less than original iPad ii, tests conducted by the same arrangement revealed that the upgraded variant was able to operate at 1 degree lower when performing intensive tasks. Functioning difference between the 2 variants, according to Anandtech is negligible.[64]

Accessories [edit]

The Smart Comprehend, get-go introduced with the iPad 2, is a screen protector that magnetically attaches to the face of the iPad. The comprehend has iii folds which let it to convert into a stand up, which is also held together by magnets.[65] While original iPad owners could purchase a black case that included a similarly folding embrace, the Smart Embrace is meant to be more minimal, easily detachable, and protects only the screen. Smart Covers take a microfiber bottom that cleans the front end of the iPad, and wakes up the iPad when the comprehend is removed. There are v different colors of both polyurethane and leather, with leather being more expensive than the polyurethane version.[66] [67]

Apple offered several more accessories for the iPad ii,[68] most of which were adapters for the proprietary thirty-pin dock connector, the iPad's merely port besides the headphone jack.[69] A dock holds the iPad upright at an angle, and has a dock connector and audio line out port. The iPad tin use Bluetooth keyboards that also work with Macs and PCs.[70] The iPad can be charged past a standalone power adapter ("wall charger") also used for contemporary iPods and iPhones, and a 10 Due west charger was included with the iPad.[69]

Reception [edit]

The iPad two received generally positive reviews, praising its Apple tree A5 processor and 720p camera. Joshua Topolsky of Engadget said that "for those of you who oasis't all the same made the leap, feel free to take a deep breath and dive in – the iPad 2 is as proficient every bit information technology gets right now. And information technology'southward actually quite good."[9] Jason Snell of Macworld said the post-obit:

"Though the iPad 2 is an improvement on the original iPad in numerous means, it's withal an evolutionary product, not a revolutionary one. If you're happy with your electric current iPad, in that location's no reason to dump it just because in that location'due south a shinier, newer one. (This is non to say that millions of people won't do just that. I mean: shiny!) If y'all've invested in iPad accessories such as a dock or case, keep in mind that yous probably won't be able to employ them with the new iPad."[71]

TechCrunch's MG Siegler stated: "Let me sum all of this up in a elementary fashion: the iPad 2, should yous buy one? Maybe — it depends on a few factors. Will you want to purchase one? Aye. Apply that information wisely."[72]

Criticism [edit]

The closed and proprietary nature of iOS has garnered criticism, particularly by digital rights advocates such as the Electronic Frontier Foundation, estimator engineer and activist Brewster Kahle, Internet-law specialist Jonathan Zittrain, and the Free Software Foundation who protested the iPad's introductory event and have targeted the iPad with their "Defective by Blueprint" campaign.[73] [74] [75] [76] Competitor Microsoft, via a PR spokesman, has as well criticized Apple's command over its platform.[77]

Technical problems [edit]

At event are restrictions imposed by the pattern of iOS, namely DRM intended to lock purchased media to Apple tree's platform, the development model (requiring a yearly subscription to distribute apps developed for the iOS), the centralized approving process for apps, besides as Apple'south full general control and lockdown of the platform itself. Particularly at issue is the ability for Apple to remotely disable or delete apps at volition. Some in the tech community have expressed business concern that the locked-down iOS represents a growing trend in Apple's arroyo to computing, particularly Apple tree's shift away from machines that hobbyists can "tinker with" and note the potential for such restrictions to stifle software innovation.[10] [78]

Some iPad 2 users reported functioning issues when running iOS eight. Apple improved functioning on the iPad 2 and the iPhone 4S on the iOS 8.1.ane update.

Commercial reception [edit]

During the beginning weekend of auction, more one one thousand thousand units were sold.[79] Soon later the showtime weekend, Ashok Kumar, a technology analyst for a financial house predicted that Apple would sell 35 meg iPad 2s in 2011.[80] Investment banking firm, Piper Jaffray monitored the initial sales of the iPad two and reported that seventy% of all iPad 2 sales were to first-time iPad buyers with 49% of buyers owning a PC compared to the initial buyers of the original iPad where only 26% of buyers owned a PC.[81] 12,000 units were sold on auction site eBay in its get-go two weeks of release.[82] When the iPhone 4S was released, rumors about the 3rd generation iPad caused a decline in iPad ii sales.[83] Official figures released in the fourth quarter of 2011 indicate that Apple sold 11.4 million iPads in the third quarter, a 166% increase from the tertiary quarter of 2010.[12] The production helped create newer, larger markets for Apple in south east Asia.

In space [edit]

In 2011 ii iPad 2 tablets were taken to the International Space Station after being approved. Other Apple products that were taken to ISS include the iPod and also 2 iPhone four phones. The other personal computing system aboard ISS were various versions of the ThinkPad laptop (IBM, subsequently Lenovo brand).[84]

Some of the applications the iPads were used for include Aroused Birds game and the ISS FIT (International Infinite Station Food Intake Tracker) for tracking astronauts' food consumption.[85] [84]
