What are all the differences between the iPad Air 4 (4th Gen) models?

Please note that the iPad Air 4 models have been discontinued. However, has been updated subsequently with current operating system support and other details and can be quite helpful for anyone buying or selling one of these tablets on the used market.

There are four iPad Air 4th Gen models -- the iPad Air 4th Gen (Wi-Fi Only), iPad Air 4th Gen (Wi-Fi+Cell US/CA), iPad Air 4th Gen (Wi-Fi+Cell Global), and iPad Air 4th Gen (Wi-Fi+Cell China). These four models -- commonly refered to as the iPad Air 4 -- vary by location sold, connectivity, battery life, identifiers, and price.

Device Similarities

All iPad Air 4 tablets share the same thin case design with rounded corners and flat sides, weigh about a pound, and have a black front. Color options for the back and sides include silver, darker "Space Gray", "Rose Gold", (Light) Green, and "Sky Blue".

Each iPad Air 4 model uses the same fully-laminated, antireflective 10.9" LED-backlit 2360x1640 "Liquid Retina" display (264 ppi, 500 nits) surrounded by a thin black bezel. The display offers "wide color" (DCI-P3) support and Apple's "True Tone" technology. They do not support ProMotion (120 Hz refresh rate).

All iPad Air 4 models also share the same six-core 3.0 GHz Apple A14 Bionic processor, a 16-core "Neural Engine", have 4 GB of RAM, and are equipped with either 64 GB or 256 GB of flash storage. In addition to a USB-C port -- the first on an iPad Air -- other connectivity includes 802.11ax (Wi-Fi 6) with HT80 with MIMO capability and Bluetooth 5.0. All have a front-mounted 7 megapixel "FaceTime HD" camera that shoots up to 1080p video, a rear-mounted 12 megapixel camera that shoots up to 4K video, dual microphones, and stereo speakers.

Other notable features include a "Touch ID" authentication sensor built into the top button -- a first for an Apple device -- as well as support for the Apple Pencil 2 (A2051, MU8F2AM/A, US$129) that conveniently charges via a magnetic connection on the side.

iOS Support Similarities

The iPad Air 4 models first shipped with iPadOS 14.1 and are fully compatible with iPadOS 15, as well. The iPad Air 4 models also are compatible with iPadOS 16, and iPadOS 17, as well.

However, running iPadOS 16, the iPad Air 4 models do not support the advanced Stage Manager, Reference Mode, Accessibility Detection, and Virtual Memory Swap features (Apple mistakenly initially listed it as compatible with Virtual Memory Swap, but this was an error).

Running iPadOS 17, the iPad Air 4 lacks support for the minor Screen Distance and External Camera for FaceTime features.

Identification Differences

When side-by-side, the Wi-Fi only and cellular iPad Air 4 models can be differentiated visually because the iPad Air 4th Gen (Wi-Fi Only) -- left -- has a solid aluminum back whereas the cellular iPad Air 4 models -- right -- have a subtle antenna line at the top of the back of each device:

However, it is not possible to visually distinguish the three cellular-capable iPad Air 4 models and it is easy to mix up all of these tablets with iPad Pro models, as well. Consequently, one of the best methods for external identification is via Model Number.

Model numbers are listed in small type toward the bottom of the back of each iPad Air:

iPad Air	Model No
iPad Air 4th Gen (Wi-Fi Only)	A2316
iPad Air 4th Gen (Wi-Fi+Cell US/CA)	A2324
iPad Air 4th Gen (Wi-Fi+Cell Global)	A2072
iPad Air 4th Gen (Wi-Fi+Cell China)	A2325

Initially, these cellular-equipped iPad Air 4 models probably will not often cross paths because of their different geographic distribution, but over time, they will find their way around the globe on the used market.

All iPad models can be differentiated by other identifiers as well, such as the Order Number, which can be located by selecting the Settings app and pressing General > About and scrolling down to what is specified as "Model" within the iOS. For example, the cellular-equipped configuration of the iPad Air 4 in green with 256 GB of storage sold in the United States is MYJ72LL/A.

Connectivity & Battery Life Differences

As noted at the beginning of this Q&A, the iPad Air 4 models have major differences in connectivity. All iPad Air 4 models support 802.11ax (Wi-Fi 6) with HT80 with MIMO capability and Bluetooth 5.0.

All cellular iPad Air 4 models support A-GPS, UMTS/HSPA/HSPA+/DC-HSDPA (850, 900, 1700/2100, 1900, 2100 MHz), and GSM/EDGE (850, 900, 1800, 1900 MHz), but Gigabit-class LTE cellular connectivity varies accordingly:

iPad Air	Model	4G LTE Bands
4 (Wi-Fi Only)	A2316	None
4 (Wi-Fi+Cell US/CA)	A2324	1, 2, 3, 4, 5, 7, 8, 11, 12, 13, 14, 17, 18, 19, 20, 21, 25, 26, 29, 30, 34, 38, 39, 40, 41, 46, 48, 66, 71
4 (Wi-Fi+Cell Global)	A2072	1, 2, 3, 4, 5, 7, 8, 11, 12, 13, 14, 17, 18, 19, 20, 21, 25, 26, 29, 30, 34, 38, 39, 40, 41, 46, 48, 66, 71
4 (Wi-Fi+Cell China)	A2325	1, 2, 3, 4, 5, 7, 8, 11, 12, 13, 14, 17, 18, 19, 20, 21, 25, 26, 28, 29, 30, 32, 34, 38, 39, 40, 41, 42, 46, 48, 66

For battery life, Apple estimates that all iPad Air 4 models provide up to ten hours of runtime on Wi-Fi whereas the cellular-equipped models provide up to nine hours using a cellular network.

Every cellular iPad Air 4 models ship unlocked. In the US, the applicable tablet works with AT&T, Sprint, T-Mobile, and Verizon. Some carriers may still require activation or configuration before it will work properly -- or at all -- on their network.

In the US and UK, if purchased from Apple or an Apple Authorized Reseller -- like site sponsor Adorama -- the cellular-capable iPad Air 4 also ships with an "Apple SIM" that is designed to support multiple carriers via a single Apple-issued Nano SIM card.

Pricing Comparison Chart

All iPad Air 4 color options cost the same amount. Original pricing is differentiated by capacity and connectivity alone:

Comparison Summary

Ultimately, the iPad Air 4 models are differentiated from each other by connectivity and battery life. Like earlier iPad Air models, the iPad Air 4 still is considered to be positioned above the entry-level "regular" iPad and below the more expensive iPad Pro line, but the iPad Air 4 actually was faster than the iPad Pro models available when the iPad Air 4 was introduced in single-core tasks. It introduced a slick "Touch ID" in the power button that the iPad Pro lacked, too.

The iPad Pro models still have bigger and better displays and better cameras, but the iPad Air 4 represents a major bump up in the capabilities of the "mid-range" iPad Air series.

Whether to choose a Wi-Fi only or cellular iPad Air 4 is a personal decision as to whether or not the A-GPS and cellular capability originally was worth the extra US$130 upfront plus the extra ongoing costs for cellular connectivity, but on the used market, the value proposition may have changed somewhat.

If the iPad Air 4 is going to be your only computer and you likely will be on the go frequently, the cellular connection could be quite worthwhile. On the other hand, if you plan to use your iPad mostly in your Wi-Fi-equipped home, office, and coffee shop (and don't mind occasionally tethering your iPad Air to a cellular-equipped device like an iPhone or Android mobile), the Wi-Fi only model could be perfect for your needs.
