History

Rumors regarding the next-generation iPad emerged shortly after the release of the third-generation iPad. At that point some speculated that the next iPad released would be of a smaller size. Further speculations emerged in July 2012 when

, and the iMac before unveiling the fourth-generation iPad and the lower-end iPad Mini. During the unveiling, Apple stated that the fourth-generation iPad would be available to pre-order online in a selected number of countries starting October 26. On November 2, Apple released the Wi-Fi model of device in 35 countries across Europe, East Asia and North America. The cellular model was released in-store a few weeks after the initial release of the device. The release of the fourth-generation iPad led to the discontinuation of its predecessor, which angered many third-generation iPad users. In response, Apple extended its 14-day return policy to 30 days. ''ITProPortal'' noted that, since the price of both models is identical, consumers that purchased the third-generation iPad within this time frame were effectively allowed to exchange their discontinued device for the fourth-generation model. On January 29, 2013, Apple announced and scheduled the launch of the 128 GB variant of 4th generation iPad. It was released on February 5, 2013. Following the announcement of the iPad Air on October 22, 2013, sales of the fourth-generation iPad were discontinued. The fourth-generation iPad was reintroduced on March 18, 2014, following the discontinuation of the iPad 2. In order to make its reintroduction a low-end device to the iPad Air, its price was cut by 20% over its original launch price. On October 16, 2014, the fourth-generation iPad was discontinued in favor of the iPad Air 2; the iPad Air took its place as the entry-level iPad at that time.

The 4th generation iPad, unlike its immediate predecessor, the 3rd generation iPad, is supported by iOS 10; however, it was announced at the Apple WWDC 2017 that the 4th generation iPad (along with the iPhone 5/5C) will not support iOS 11. iOS 10.3.3 is the latest and final version of iOS to include support for the Wi-Fi only models of these devices. iOS 10.3.4 is the latest and final version of iOS to include support for the cellular models of these devices, released to fix an issue caused by the GPS week number rollover.

from the prior model. As with all previous generations of iPhone and iPad hardware, there are four buttons and one switch on the fourth-generation iPad. With the device in its portrait orientation, these are: a "home" button on the face of the device under the display that returns the user to the home screen, a ''wake/sleep'' button on the top edge of the device, and two buttons on the upper right side of the device performing ''volume up/down'' functions, under which is a switch whose function varies according to device settings, generally functioning either to switch the device into or out of silent mode or to lock/unlock the orientation of the screen. Externally, the fourth-generation iPad is identical to its predecessor apart from the differences between dock connectors used and change of manufacturers that produce the display. In addition, the Wi-Fi only version weighs 652 grams while the cellular model weighs 662 grams – 2 grams heavier than their respective predecessors. The display responds to other sensors: an ambient light sensor to adjust screen brightness and a 3-axis

power adapter and Lightning connector. While it can be charged by an older USB port from a computer, these are limited to 500 milliamps (0.5 amps). As a result, if the iPad is in use while powered by a computer, it may charge very slowly, or not at all. High-power USB ports found in newer computers and accessories provide full charging capabilities. Apple claims that the battery can provide up to 10 hours of video, audio playback, or web surfing on Wi-Fi, 9 hours of web surfing over a cellular connection, or one month on standby. Like any rechargeable battery, the iPad's battery loses capacity over time. However, the iPad's battery is not user-replaceable. In a program similar to iPod and iPhone battery-replacement programs, Apple promised to replace an iPad that does not hold an electrical charge with a refurbished unit for a fee. During the battery replacement process, user data is not preserved/transferred, and repaired or refurbished units come with a new case. The warranty on the refurbished unit may vary between jurisdictions.

Reception

The fourth-generation iPad received positive reviews from critics and commentators. The review by Gareth Beavis of '' TechRadar'' praised the device for its high-resolution Retina Display, which ''TechRadar'' wrote is "...one of the most impressive we've seen on a tablet to date." However, the reviewer also wrote that the screen "lacks the 'punch' seen in Super AMOLED screens seen on devices like the Samsung Galaxy Note 2." The review also praised the interface of the iPad for its simple design and easy to use layout. Additionally, other aspects, such as the design of the iPad and updated SoC were noted and praised in the review. Critically, Beavis noted that the iPad can still moderately heat up under medium usage, however not to the extent seen in the third-generation iPad. Tim Stevens of ''

and third-generation iPad. The performance increase of the fourth-generation iPad varies between tests, however an increase is nonetheless evident. Furthermore, battery longevity tests conducted by the same organization suggests that the battery of the fourth-generation iPad is able to last longer than its predecessor. However, the battery of the updated iPad 2 is able to outlast the fourth-generation iPad.


Commercial reception

In the first weekend of sales of the iPad Mini and fourth-generation iPad, Apple reported that it sold an aggregated number of 3 million units. ''TechRadar'' noted that the first weekend sales figures for the fourth-generation iPad are lower than corresponding figures for the third-generation iPad, which sold 3 million units in its first weekend. Subsequent reports and analysis such as that from David Hsieh, a technology analyst, suggest that the iPad mini is selling better than the fourth-generation iPad. Despite the noted slump in sales, Apple's stock price, in direct response to the figures released, rose by 1.4% to $584.62 on November 5.


Criticism

In a repairability review conducted by iFixit, the fourth-generation iPad scored 2 out of 10 (10 being the easiest to repair) due to the use of adhesive to attach components. However, reviewers noted that several components such as the screen and battery could be removed easily for replacement.
