iPad Air A12 Bionic 2019

It's important to know that this A2154 iPad Air (3rd Gen) model, sold only in mainland China, supports Gigabit-class LTE on bands 1-5, 7, 8, 11-14, 17-21, 25, 26, 28-30, 34, 38-42, 46, and 66, but not band 71.

Regardless of connectivity, the iPad Air 3rd Gen models are marketed as offering "high-end features and performance at a breakthrough price." They have newer, faster internals than the iPad Pro 10.5" models they replaced, but with a lower-quality display and inferior cameras and speakers.

All iPad Air 3rd Gen devices feature a fully-laminated, antireflective 10.5-inch LED-backlit 2224x1668 (264 ppi, DCI-P3 color gamut) "Retina" display, but they do not support "ProMotion technology" and its 120 Hz refresh rate.

These models are powered by an Apple A12 Bionic processor, 3 GB of RAM, and come with either 64 GB or 256 GB of flash storage. They are available in Black and Space Gray, White and Silver, or White and Gold cases.

Other notable features include dual cameras, dual-band 802.11a/b/g/n/ac Wi-Fi with HT80 with MIMO, Bluetooth 5.0, dual microphones, and a single set of stereo speakers. They also have a standard 3.5 mm headphone jack.

Connectivity and power are provided by a Lightning port. A "Smart Connector" supports the same small Apple Smart Keyboard as the earlier 10.5" iPad Pro. It is also compatible with the original Apple Pencil.

Battery life is rated at 10 hours of Wi-Fi web surfing, video, or music, and 9 hours on cellular data. This model has a nano-SIM slot for traditional SIM cards.

The iPad Air 3rd generation for the Chinese market (A2154) was seen as a strategic and powerful update, bringing pro-level features to a more accessible price point. The inclusion of the fast A12 Bionic chip and support for the first-generation Apple Pencil were its most lauded features, turning it into a highly capable device for both work and play. The 10.5-inch laminated display was a significant step up from the standard iPad. This model's cellular connectivity was specifically configured for China's networks, ensuring reliable performance for local users. While it lacked some of the high-end features of the iPad Pro, such as ProMotion, it was widely regarded as a fantastic option for Chinese consumers wanting a powerful, versatile tablet without the full expense of a Pro model.
