The 128GB Apple iPad mini 4 features 7.9″ Retina Display with a native resolution of 2048 x 1536, showing up to 3.1 million pixels at 326 ppi. The Retina Display’s capacitive touchscreen lets you utilize all the multi-touch gestures of iOS 9.
The mini 4 features Apple’s A8 processor with their 2nd Generation 64-bit architecture, allowing for more robust and powerful apps such as video editing, 3D modeling and CAD, and 3D gaming. Also, the A8 chip supports Metal, a more efficient technology that enables the iPad mini to render detailed graphics and visual effects.
Accompanied by the A8 chip is the M8 motion coprocessor, which measures the motion of the iPad mini via the accelerometer, gyroscope, compass, and barometer, lightening the load of the A8 chip. This frees up the A8 chip to process multiple tasks while enabling it to maintain fast performance. The iPad mini may have the Retina Display, but it still manages to maintain its 10-hour battery life. That’s because the A8 chip isn’t just more powerful; it’s also more efficient.
The Retina Display of the iPad mini 4 has been designed with all components combined into one layer. This helps eliminate gaps between layers, as well as the internal reflectance caused by those gaps. This helps the 7.9″ 2048 x 1536 touchscreen render lifelike colors, text, and images with improved contrast, sharpness, and vividness at 326 pixels per inch and a total of over 3.1 million pixels
Apple A8 System on a Chip
Thanks to the A8 chip, apps run fast on the iPad mini 4. The A8 is Apple’s 2nd generation 64-bit architecture, and its CPU runs up to 30% faster than the A7, while its graphics run up to 60% faster than the A7
M8 Motion Coprocessor
When you’re in motion, the M8 motion coprocessor continuously measures data from the accelerometer, compass, gyroscope, and barometer. This helps offload work from the A8 chip for improved power efficiency. The motion coprocessor also continuously calibrates all five sensors, so when you want to play a game or use Maps, iPad mini 4 is ready and able
8-Megapixel iSight Camera
The f/2.4 iSight camera has been re-designed with an 8-megapixel sensor that captures images at a native resolution of 3264 x 2448 and 1080p HD video. The image signal processor in the A8 chip also features improved face-detection technology to keep more – and smaller – faces in focus as well as improved noise reduction. The camera also features time-lapse video, exposure control, 120 fps slo-mo, a burst mode, a timer mode, and a high-resolution panorama mode
With Touch ID, you can use your finger and the Home button to unlock your iPad. Touch ID also has 360° range, so no matter how you’re holding it – portrait, landscape, or anything in between – your iPad knows who you are. Touch ID also unlocks more than just your iPad and allows you to sign in to secure apps, make one-touch purchases in iTunes, iBooks, the App Store, and through Apple Pay
