However, there was minimal focus directly on the new device, with only a brief mention at the end of the iPad Pro portion of the keynote.

The device is compatible with iOS 9.1, which was released on October 21, 2015, which adds the News app for the UK and Australia as well as additional emoji and other bug fixes.

It was revealed in WWDC 2022 that iPadOS 16 won't be supported on the Mini 4, along with the iPad Air 2.

Along with the iPad Air 2, there are 2 GB of RAM, allowing the device to support the advanced multitasking features made available with the iOS 9 operating system.

Like the iPad Mini 3 that came before it, the iPad Mini 4 is capable of making mobile payments via Apple Pay in combination with the Touch ID sensor, although this can only be done in apps as the device lacks the NFC antenna required for payments at a merchant terminal.

Reviews have generally been positive, with The Verge giving the iPad Mini 4 a 9/10, praising the display, fast performance, great camera, and multitasking but disappointed with the speakers and chamfered edges.
