Informally dubbed by Apple as a smaller iPad Air 2, the iPad mini 4 models pack comparable, though not identical, components into a more compact form factor.
Both the Wi-Fi only model and its Cellular-enabled counterpart in the iPad mini 4 series are equipped with a 7.9-inch 2048x1536 (326 ppi) LED-backlit IPS touch-sensitive display featuring an antireflective coating. They are powered by a dual-core 1.5 GHz Apple A8 processor, have 2 GB of RAM, and offer storage options of 16 GB, 32 GB, 64 GB, or 128 GB. The devices are available in three housing colors: silver with a white front, gold with a white front, and a medium-toned "space" gray with a black front.
Other key features include a dual-camera system: a rear-mounted 8-megapixel "iSight" camera for stills and 1080p video, and a front-mounted 1.2-megapixel "FaceTime HD" camera for stills and 720p video. They also support dual-band 802.11a/b/g/n/ac Wi-Fi with HT80 with MIMO and Bluetooth 4.2, along with dual microphones and speakers. A Lightning port provides power and computer connectivity.
The battery life for this iPad mini 4 is stated to be up to 10 hours of "surfing the web on Wi-Fi, watching video, or listening to music."
This specific Wi-Fi Only model (A1538) lacks support for 4G LTE connectivity and A-GPS.
