iPad Air A14 Bionic 2020

It's important to know that this A2072 iPad Air 4th Gen supports Gigabit-class LTE on bands 1-5, 7, 8, 11-14, 17-21, 25, 26, 28-30, 32, 34, 38-42, 46, 48, and 66, but not band 71. Confusingly, Apple's initial marketing listed this model for Hong Kong and Taiwan only, but this was incorrect; it was sold globally outside North America.

The iPad Air 4th Gen (Wi-Fi Cellular - Global) features a fully-laminated, antireflective 10.9" LED-backlit 2360x1640 "Liquid Retina" display (264 ppi, 500 nits) framed by a thin black bezel and housed in a slim case with rounded corners and flat sides. It comes in five metallic colors: silver, "Space Gray," Rose Gold, (Light) Green, and Sky Blue.

This iPad Air is powered by a six-core Apple A14 Bionic processor and a 16-core "Neural Engine," with 4 GB of RAM and either 64 GB or 256 GB of flash storage. Key features include a "Touch ID" sensor in the top button and support for the Apple Pencil 2nd Gen (A2051, MU8F2AM/A, US$129), which charges magnetically. It has a front 7-megapixel "FaceTime HD" camera for up to 1080p video and a rear 12-megapixel camera for up to 4K video.

Connectivity includes a USB-C port, A-GPS, 802.11ax (Wi-Fi 6) with HT80 with MIMO, and Bluetooth 5.0. It also has dual microphones and stereo speakers. Battery life is rated at 10 hours of Wi-Fi web surfing or video, and 9 hours on cellular data.

Compared to its predecessor, the iPad Air 4th Gen models are a significant upgrade, sharing more with the high-end iPad Pro. They are physically smaller but have a larger display, a more powerful architecture, advanced keyboard support, USB-C, and support for the advanced Apple Pencil 2nd Gen and top-button "Touch ID" sensor.

The global cellular model of the iPad Air 4 was a revolutionary update, praised for bringing the modern, all-screen design of the iPad Pro to a more mainstream audience. The powerful A14 Bionic chip provided excellent performance, and the move to USB-C was a huge step forward in terms of connectivity and versatility. Support for the 2nd generation Apple Pencil and the Magic Keyboard transformed its capabilities as a productivity tool. The new Touch ID sensor integrated into the power button was a clever and well-executed feature. For international users, this A2072 model provided fast and reliable LTE connectivity across a wide range of bands. It was widely seen as the perfect iPad for most people, successfully blurring the lines between the Air and Pro models and offering incredible value.
