iPad 6 (2018, A10 series) vs iPad Air 4 (2020, A14 series)

The iPad 2018 (6th Generation) and the iPad Air 2020 (4th Generation) are two distinct Apple tablets, released in March 2018 and October 2020, respectively. While both devices operate on Apple's iPadOS, they cater to different user needs through variations in their internal components, display technology, and overall design philosophy. The iPad Air 2020 represents a more modern approach with a focus on enhanced performance and a contemporary aesthetic, whereas the iPad 2018 offers a more traditional iPad experience.

The longevity of an electronic device is significantly influenced by its release date and the manufacturer's software support policy. These two iPads, separated by approximately two and a half years, exhibit notable differences in their expected practical lifespan.

• Software Support: The iPad 2018, launched with iOS 11.3, was upgradeable to iPadOS 17.2 or 17.3. However, it will not receive the iPadOS 18 update. In contrast, the iPad Air 2020, which debuted with iPadOS 14, supports iPadOS 26.4.1 as of April 2026. Apple typically provides major OS updates for 5 to 8 years, meaning the iPad Air 2020 has a considerably longer runway for software support.
• Practical Lifespan: User feedback indicates that the iPad 2018 is beginning to show its age, with some users reporting lag and limitations in multitasking due to its 2GB of RAM. The iPad Air 2020, with its newer hardware, is generally considered capable of handling current tasks and receiving updates for several more years, offering a longer period of optimal performance.
• Repairability: While specific repairability scores can vary, both models generally adhere to Apple's design principles, which can make user-level repairs challenging. However, professional repair services are available for both, contributing to their potential for extended use.

Performance is a key differentiator between these two iPad models, largely due to the advancements in processor technology over their respective release cycles. The iPad Air 2020 offers a more robust and future-ready experience.

• Processor Capabilities: The iPad 2018 is equipped with an A10 Fusion chip, while the iPad Air 2020 features a more advanced A14 Bionic chip. The A14 Bionic is significantly more powerful and energy-efficient, translating to smoother operation for demanding applications, faster app loading times, and more fluid multitasking. Users of the iPad 2018 may experience noticeable slowdowns and limitations when running newer, resource-intensive apps or engaging in heavy multitasking.
• Multitasking and Responsiveness: The iPad Air 2020 benefits from 4GB of RAM, compared to the iPad 2018's 2GB. This increased RAM allows the iPad Air 2020 to handle multiple applications simultaneously with greater ease, reducing instances of apps reloading when switching between them. The overall system responsiveness on the iPad Air 2020 is more immediate, providing a snappier user experience.
• Storage and Battery Behavior: Both models were available with various storage options, though the iPad Air 2020 typically started with a larger base storage of 64GB compared to the iPad 2018's 32GB. In terms of battery, both devices are rated for up to 10 hours of web browsing or video playback. However, the A14 Bionic's improved efficiency in the iPad Air 2020 can contribute to better real-world battery endurance, especially during intensive tasks, as it manages power consumption more effectively.

The visual experience on these two iPads presents distinct differences, primarily in screen size, display technology, and advanced features.

• Display Technology and Size: The iPad 2018 features a 9.7-inch Retina IPS LCD with a resolution of 2048 x 1536 pixels, resulting in a pixel density of 264 pixels per inch (ppi). The iPad Air 2020 boasts a larger 10.9-inch Liquid Retina IPS LCD with a resolution of 2360 x 1640 pixels, maintaining a similar pixel density of 264 ppi. The larger screen of the iPad Air 2020, combined with its more modern, edge-to-edge design, offers a more expansive and immersive viewing experience.
• Clarity and Advanced Features: While both displays offer good clarity, the iPad Air 2020 includes several enhancements. It supports True Tone technology, which automatically adjusts the display's white balance to match the ambient light, and features P3 wide color support for more vibrant and accurate colors. Additionally, the iPad Air 2020's display is fully laminated and includes an anti-reflective coating, which reduces glare and improves the visual quality, especially in bright environments. The iPad 2018 lacks these advanced display features and has a non-laminated display, which can result in a slight gap between the glass and the LCD.
• Refresh Rate: Both tablets feature a standard 60Hz refresh rate, providing a smooth experience for general use, but neither offers the higher refresh rates found in some more premium tablets.

The camera systems on the iPad 2018 and iPad Air 2020 reflect the technological advancements made in tablet photography and video capabilities over their respective release periods.

• Rear Camera Performance: The iPad 2018 is equipped with an 8-megapixel rear camera. The iPad Air 2020 features a more capable 12-megapixel rear camera, which also supports 4K video recording. This difference translates to the iPad Air 2020 capturing more detailed photos and offering higher quality video recording, making it better suited for casual photography and capturing memories.
• Front Camera and Video Calls: For video calls and selfies, the iPad 2018 includes a 1.2-megapixel FaceTime HD front camera. The iPad Air 2020 significantly upgrades this to a 7-megapixel FaceTime HD front camera, capable of 1080p video recording. This improvement means clearer and sharper video calls and better quality for self-portraits on the iPad Air 2020.
• Audio Experience: The iPad 2018 features dual stereo speakers, typically located at the bottom of the device. The iPad Air 2020 also includes stereo speakers, which provide a more immersive audio experience, particularly when holding the tablet in landscape orientation for media consumption. Both devices offer adequate microphone quality for calls and basic recording.
