iPad 6 (2018, A10 series) vs iPad mini 6 (2021, A15 series)

The iPad 2018, released in March 2018, and the iPad Mini 2021, launched in September 2021, represent different approaches within Apple's tablet lineup. While both devices operate on iPadOS, they cater to distinct user preferences primarily through their size, internal components, and feature sets. The iPad 2018 offers a traditional larger display experience, whereas the iPad Mini 2021 focuses on enhanced portability and more modern capabilities.

The longevity of a tablet is influenced by its release date, software support, and repairability. These two iPads, separated by a few years, offer different expectations in these areas.

• Software Support: The iPad 2018 shipped with iOS 11.3 and can be updated to iPadOS 17.2. While it has received substantial updates, major OS support may be nearing its end, with some indications that iPadOS 18 could be its last significant update, or that it may primarily receive security updates going forward. In contrast, the iPad Mini 2021, launching with iPadOS 15, is expected to receive major OS updates for several more years, likely extending its functional lifespan for current applications.
• Repairability: Both iPads generally present challenges for repair due to Apple's design choices involving extensive use of adhesive. The iPad 2018 received an iFixit repairability score of 2 out of 10, largely due to strong glues securing internal components. While its display is not laminated, potentially making screen replacement less complex, accessing other internal parts remains difficult. The iPad Mini 2021, like most iPads, also features a design that prioritizes slimness and rigidity, which typically results in low repairability scores.
• Practical Lifespan: Given its more recent release and more powerful internal components, the iPad Mini 2021 is likely to offer a longer practical lifespan, remaining capable of running demanding applications and receiving software updates for a greater duration compared to the iPad 2018.

Performance is a key differentiator between these two tablets, largely due to the generational gap in their internal processing power and memory configurations.

• Processing Power: The iPad 2018 is equipped with an A10 Fusion chip, which capably handles everyday tasks such as web browsing, email, and light productivity applications. However, users engaging in more demanding activities like graphically intensive gaming or extensive multitasking may notice slower response times or occasional stutters. The iPad Mini 2021 features a more advanced A15 Bionic chip, providing a significant boost in performance. This allows for smoother operation across all applications, faster loading times, and a more fluid experience when running multiple apps simultaneously or engaging with high-performance tasks.
• Memory and Storage: The iPad 2018 comes with 2GB of RAM, which can lead to apps reloading more frequently when switching between them, especially with several open. Storage options for the iPad 2018 include 32GB and 128GB. The iPad Mini 2021 doubles the RAM to 4GB, significantly improving multitasking capabilities and app retention in memory. Its storage options start at 64GB and go up to 256GB, offering more base storage and a higher maximum capacity for users with larger digital libraries or more applications.
• Battery Performance: Both devices are designed to offer up to 10 hours of web browsing or video playback on a single charge. In real-world usage, the iPad 2018 typically provides between 5 to 11 hours depending on the intensity of use, with some users reporting excellent battery life for note-taking and studying. The iPad Mini 2021 also delivers around 8 to 10 hours of battery life with more intensive use, and some tests show it lasting nearly 11 hours for continuous web browsing. While both offer solid battery performance for their respective designs, the iPad Mini 2021's more efficient processor contributes to its consistent endurance.

The display is a primary interface for tablets, and these two models offer different visual experiences, largely influenced by their size and display technology advancements.

• Display Technology and Size: The iPad 2018 features a 9.7-inch Retina IPS LCD. This display is not fully laminated, meaning there is a slight air gap between the glass and the LCD panel, which can sometimes be noticeable. The iPad Mini 2021, on the other hand, boasts an 8.3-inch Liquid Retina IPS display. This display is fully laminated, offering a more direct and immersive viewing experience with reduced reflections.
• Resolution and Clarity: The iPad 2018 has a resolution of 2048 x 1536 pixels, resulting in a pixel density of 264 pixels per inch (ppi). The iPad Mini 2021 offers a resolution of 2266 x 1488 pixels, but due to its smaller screen size, it achieves a higher pixel density of 326 ppi, providing a sharper and more detailed image. Both displays offer good clarity for typical viewing, but the Mini's higher ppi contributes to finer detail.
• Brightness and Color: The iPad Mini 2021 features a maximum brightness of 500 nits, along with support for Wide Color (P3) and True Tone technology, which adjusts the display's white balance to match the ambient light. While the iPad 2018's brightness is not explicitly stated in nits in the provided information, it offers a good viewing experience indoors. Neither device features a high refresh rate display, with both operating at a standard 60Hz.

Camera capabilities have evolved significantly between these two generations, particularly in terms of resolution, features, and front-facing camera performance.

• Rear Camera System: The iPad 2018 includes an 8MP rear camera with an f/2.4 aperture. This camera performs adequately in well-lit conditions, capturing decent images, but its performance diminishes in low-light environments, often resulting in noisy or less vibrant photos. The iPad Mini 2021 features an upgraded 12MP Wide camera with a wider f/1.8 aperture, allowing for better light capture and improved image quality, especially in challenging lighting.
• Front Camera and Video Calls: The iPad 2018 has a 1.2MP front-facing camera with an f/2.2 aperture, suitable for basic video calls but lacking in detail and low-light performance. The iPad Mini 2021 significantly enhances the front camera experience with a 12MP Ultra Wide camera (f/2.4) that includes Center Stage. This feature automatically keeps the user centered in the frame during video calls, even as they move, making it highly beneficial for virtual meetings and family chats. While its low-light performance for the front camera is noted as not the strongest, its wider field of view is advantageous for group calls.
• Video Recording: For video, the iPad 2018 can record 1080p video at 30 frames per second with its rear camera and 720p with its front camera, but it lacks advanced stabilization. The iPad Mini 2021 offers more robust video capabilities, with its rear camera capable of recording up to 4K at 60 frames per second and its front camera recording 1080p at 60 frames per second, providing smoother and higher-resolution video capture.
• Audio Experience: The iPad 2018 features dual speakers located at the bottom, which provide decent audio quality but can sound lopsided when the tablet is held in landscape orientation. The iPad Mini 2021 includes stereo speakers, offering a more balanced and immersive audio experience for media consumption.
