iPad mini 3 (2015, A8 series) vs iPad Pro (2017, A10 series)

The practical lifespan of a tablet is often determined by its hardware capabilities and the duration of software support it receives. These two models, released two years apart, have different trajectories in this regard.

• Release Timeline and OS Support: The iPad Mini 4, released in 2015, received its last major operating system update with iPadOS 15.8.7, released in March 2026. It does not support iPadOS 16 or later versions. In contrast, the iPad Pro 2017, released in 2017, supports iPadOS 17 and is expected to receive iPadOS 18, offering a longer period of access to the latest features and security updates.
• Software Longevity Expectations: Users of the iPad Mini 4 will find that while it continues to function, newer applications and features requiring more recent iPadOS versions may not be available. The iPad Pro 2017, with its more recent release and continued software support, provides a longer window for compatibility with current and upcoming software.
• Repairability: Both devices, typical of their manufacturer, are not designed for easy user repair. Professional repair services are generally required for internal component issues.

Performance is a key differentiator between these two tablets, largely due to the advancements in processing technology over their respective release years.

• Processor Capabilities: The iPad Mini 4 is equipped with a processor that handles everyday tasks like web browsing, email, and light gaming smoothly. The iPad Pro 2017 features a more advanced processor, providing a substantial increase in speed and efficiency. This allows it to manage demanding applications, complex multitasking, and graphic-intensive tasks with greater responsiveness.
• Multitasking and Responsiveness: The iPad Mini 4, with its 2GB of RAM, supports basic multitasking features like Split View, but can experience slowdowns with multiple demanding apps open. The iPad Pro 2017, with 4GB of RAM, offers a more fluid multitasking experience, allowing users to switch between applications and run several simultaneously without significant performance degradation.
• Battery Behavior: Both devices are designed to offer a full day of typical use. User reports for the iPad Mini 4 indicate around 8-10 hours of mixed usage, though heavy gaming can reduce this. The iPad Pro 2017 also aims for approximately 10 hours of web browsing or video playback, with heavy tasks like photo editing or intensive drawing potentially reducing this to 6-7 hours.

The display is a significant area where the iPad Pro 2017 offers notable enhancements over the iPad Mini 4, impacting the visual experience for users.

• Display Technology and Clarity: Both tablets feature IPS LCD Retina displays, offering sharp text and clear images. The iPad Mini 4 has a 7.9-inch display with a resolution of 2048 x 1536 pixels, resulting in a pixel density of 326 pixels per inch (ppi). The iPad Pro 2017 comes in 10.5-inch and 12.9-inch sizes, with resolutions of 2224 x 1668 pixels and 2732 x 2048 pixels respectively, both at 264 ppi.
• Refresh Rate and Smoothness: A key difference is the iPad Pro 2017's ProMotion technology, which enables an adaptive refresh rate up to 120Hz. This results in smoother scrolling, more responsive touch input, and a more fluid experience, particularly noticeable in fast-paced content or when using a stylus. The iPad Mini 4 has a standard 60Hz refresh rate.
• Brightness and Color: The iPad Pro 2017's display is generally brighter and supports a wider color gamut (P3), offering more vibrant and accurate colors, along with True Tone technology that adjusts the display's white balance to match ambient light. The iPad Mini 4's display provides good color accuracy for its generation.

While tablets are not typically primary photography devices, their camera systems are important for video calls, document scanning, and occasional photo capture. There are clear differences in the capabilities of these two models.

• Rear Camera Performance: The iPad Mini 4 features an 8-megapixel rear camera capable of capturing decent photos in good lighting conditions and recording 1080p video. The iPad Pro 2017 significantly upgrades this with a 12-megapixel rear camera, featuring a wider aperture and optical image stabilization (OIS), leading to improved low-light performance and sharper images. It can also record 4K video.
• Front Camera Quality: For video calls and selfies, the iPad Mini 4 includes a 1.2-megapixel front-facing camera. The iPad Pro 2017 offers a 7-megapixel front-facing camera, providing clearer and more detailed images for video conferencing and self-portraits.
• Audio Experience: The iPad Mini 4 has stereo speakers, providing adequate sound for media consumption. The iPad Pro 2017 features a four-speaker audio system, delivering a richer and more immersive sound experience, particularly beneficial for watching movies or listening to music.

Beyond core performance and display, several other features contribute to the overall user experience and utility of these tablets.

• Connectivity Options: Both devices support Wi-Fi 802.11ac and Bluetooth 4.2. Cellular models of both tablets offer LTE connectivity for internet access away from Wi-Fi.
• Port Types and Accessories: Both tablets utilize the Lightning port for charging and data transfer. The iPad Pro 2017 distinguishes itself with support for the first-generation Apple Pencil and the Smart Keyboard, transforming it into a more versatile tool for productivity and creative tasks. The iPad Mini 4 does not support these accessories.
• Biometric Security: Both the iPad Mini 4 and iPad Pro 2017 feature Touch ID, an integrated fingerprint sensor in the home button, for secure authentication and purchases.
• Physical Characteristics: The iPad Mini 4 is designed for portability, weighing approximately 299-304 grams and measuring 6.1 mm thin, making it easy to hold with one hand. The iPad Pro 2017 models are larger and heavier, with the 10.5-inch model weighing around 469-477 grams and the 12.9-inch model around 677-692 grams, both 6.1-6.9 mm thin.
