Apple’s latest iOS 26 and iPadOS 26 releases bring a refreshed user experience and new features, but the update cycle also means a small number of older devices are left behind. In a year when Apple’s software teams push forward with performance improvements and design refinements, the casualty list remains surprisingly short. The core takeaway is that most users can upgrade, enjoy the new Liquid Glass visuals and other enhancements, while a precise subset of devices will no longer be able to run the new operating systems. Below is a comprehensive look at what changes with iOS 26 and iPadOS 26, which devices are affected, why they are dropped, how security and ongoing support are handled, and what users and developers should expect as the ecosystem moves forward.
Overview of iOS 26 and iPadOS 26 compatibility
The annual cadence of Apple’s software releases is well established: new versions arrive with a host of improvements, sometimes accompanied by hardware compatibility shifts. In the case of iOS 26 and iPadOS 26, Apple’s engineering and product teams delivered a comparatively restrained drop in device support. This year’s update cycle is notable for avoiding a broad cull of devices; instead of removing compatibility for a wide swath of iPhone and iPad models, Apple chose to retire only a small, clearly defined set of legacy devices.
This year’s iOS 26 update will not install on the iPhone XR or iPhone XS models from 2018. On the iPad side, iPadOS 26 will not install on the 7th-generation iPad released in 2019. For every other device currently capable of running iOS or iPadOS 18, the transition to the newer versions is expected to proceed without major compatibility hurdles. The new versions bring with them a refreshed user interface and the distinctive Liquid Glass aesthetic, among other features designed to enhance performance, security, and overall user experience.
To help readers visualize the compatibility landscape, imagine a core set of devices that remain eligible for the upgrade, paired with a very small number that will not. The bulk of Apple’s supported devices continue to receive the latest system software, which implies continued access to security patches, new features, and ongoing app compatibility. In practical terms, this means the ecosystem continues to be robust for most users, while a specific, very defined minority must explore alternative upgrade paths or remain on their current OS if upgrade requirements cannot be met.
A broad rule of thumb remains true: devices that can run iOS 26 or iPadOS 26, respectively, will be able to upgrade and enjoy the new interface enhancements, performance gains, and the broader feature set. The new design language includes the Liquid Glass look, a signature element designed to deliver smoother animations and a more polished feel across apps and system surfaces. In addition to visual updates, Apple’s software engineering teams typically weave in security improvements, privacy protections, and under-the-hood optimizations that enhance battery life, system responsiveness, and app startup times. For most users, the upgrade is a straightforward process that yields tangible improvements.
The practical takeaway for device owners is clear: confirm whether your device is on the supported list for iOS 26 or iPadOS 26, prepare for the update by backing up data, and review any developer-facing changes that could affect app behavior. This year’s announcement reinforces a familiar pattern: Apple keeps a broad swath of devices up to date while retiring only those that are demonstrably challenged by the demands of the latest software stack.
To aid clarity, here is a concise compatibility snapshot that mirrors the general structure of Apple’s guidance, adapted for readers who want an at-a-glance reference. The devices listed below reflect the official upgrade path for iOS 26 and iPadOS 26:
- iOS 26: Compatible with all iPhone models that can support iOS 26 except the iPhone XR and iPhone XS (these two models are not eligible for iOS 26).
- iPadOS 26: Compatible with all iPad models that can support iPadOS 26 except the 7th-generation iPad (this model is not eligible for iPadOS 26).
This compatibility framework emphasizes that the vast majority of active iPhone and iPad users can expect to upgrade, while a narrow subset will not. The sections below explore the reasons behind these decisions, the implications for users, and what to expect going forward as Apple refines its operating system portfolio.
Dropped devices: XR, XS, and the 7th-generation iPad
Understanding which devices are out of scope for iOS 26 and iPadOS 26 requires looking at the hardware foundations of the two iPhone models and the single iPad that were retired. The iPhone XR and iPhone XS, both introduced in 2018, rely on Apple’s A12 Bionic chip. This chip represented a significant leap at the time, delivering improved performance and energy efficiency compared to earlier generations. However, by the time iOS 26 rolled around, the A12’s architectural and feature set no longer aligned with the demands of the newest software stack. Consequently, Apple elected not to provide iOS 26 for these devices.
On the iPad side, the 7th-generation iPad, released in 2019, remained powered by Apple’s A10 Fusion architecture. This chip was a meaningful upgrade at launch, but as Apple’s software engine matured, the A10 Fusion fell further behind in terms of performance headroom and feature parity with the latest system software guarantees. While many iPad models with newer chips continue to benefit from ongoing OS improvements, the 7th-generation iPad’s hardware could not sustain the newer iPadOS 26 experiences without unacceptable performance trade-offs or compromised user experiences.
Apple’s policy for deprecating devices does not hinge on a single factor alone. Although Apple does not frequently publish explicit reasons for each retirement, industry observers and hardware analysis suggest a combination of aging hardware, limited RAM, graphics capabilities, and the increasing demands of modern software frameworks as primary drivers. In the case of the 7th-generation iPad, the A10X-class lineage had moved beyond the threshold where Apple could confidently deliver a consistently smooth experience across all new OS features, while still ensuring a broad range of security and privacy protections.
The two iPhone models—XR and XS—are not the only Apple devices ever retired from iOS versions, but they illustrate a consistent pattern: once a device’s core processing capabilities, neural engine tasks, and GPU performance fall behind the requirements of new OS features, the manufacturer typically withdraws support to preserve overall system integrity and user experience. The A12 chip in XR and XS, while still capable for many tasks, is sometimes outpaced by modern system demands, particularly in areas like graphics rendering, machine learning tasks, and memory bandwidth. This is the practical calculus behind the decision to end iOS 26 support for these two iPhone models.
For the 7th-generation iPad, the A10 Fusion chip presents a similar equation. While the device remains perfectly adequate for a broad set of tasks, it encounters limitations with newer APIs, optimized rendering paths, and features that require more modern hardware acceleration. Apple’s approach prioritizes delivering a consistent baseline experience for the majority of users while clearly delineating the devices that cannot participate in the latest OS release.
In essence, the decision to retire XR, XS, and the 7th-generation iPad is a measured one grounded in hardware realities. It reflects a balance between enabling the newest software capabilities and maintaining a high standard of performance and security across the rest of the ecosystem. Apple’s broader strategy remains to minimize disruption for the largest possible population of users while ensuring that the devices that continue to support iOS 26 and iPadOS 26 can fully capitalize on the updated features and protections included in the release.
Hardware implications: A12 versus A10X, and why some devices are dropped
The technical rationale behind dropping specific devices often centers on the capabilities of the underlying silicon. The iPhone XR and XS are powered by the A12 Bionic chip, a capable processor in its own right, but by the time iOS 26 arrived, several of the newer features in the OS and its sub-systems demanded more robust hardware resources, including faster memory bandwidth, improved GPU performance, and enhanced neural processing capabilities. Although the A12 remains a potent chip for many tasks, the software stack in iOS 26 introduces features and optimizations that are optimized for newer CPUs and GPUs. Apple’s objective is to deliver consistent performance and security across all supported devices, and when a subset of devices cannot meet those thresholds reliably, retirement from the update becomes the practical choice.
In contrast, the 7th-generation iPad relies on the A10 Fusion chip, with the subsequent generation introduced later carrying the A10X chips in many contexts. The A10X retains a more advanced feature set than the original A10, but the overarching trend for iPadOS updates is to push toward newer architectural designs that can handle higher memory bandwidth, improved graphics pipelines, and more efficient system-level APIs. The 7th-generation iPad’s hardware simply cannot sustain the demands of iPadOS 26 without sacrificing the smoothness, stability, and energy efficiency Apple aims to guarantee in its current software ecosystem.
From a broader perspective, Apple’s hardware cadence often pairs with the software team’s need to provide robust security, modern runtime environments, and compatibility with evolving app ecosystems. Newer OS features frequently rely on accelerators, specialized instruction sets, or improved memory handling that older chips struggle to emulate efficiently. The XR/XS pair and the 7th-generation iPad become outliers when measured against these requirements, which explains Apple’s decision to limit the upgrade path for those specific devices. The result is a more uniform experience across supported devices and fewer edge-case performance issues that can arise when older hardware attempts to run the most recent software features.
For developers, the implications are notable. App feature parity, API deprecations, and performance expectations evolve with each major OS release. While many apps can transparently support a broad range of devices, some newer capabilities may not be available on retired hardware. This reality can influence app optimization decisions, testing priorities, and the way developers approach compatibility shims and fallback experiences for older devices that remain in circulation in business environments or personal collections. The long-term effect is a cleaner, more stable baseline for applications running on iOS 26 and iPadOS 26-capable devices.
In sum, the hardware-based retirement of XR, XS, and the 7th-generation iPad reflects a practical alignment of software requirements with hardware realities. It is not a broad purge; it is a precise, measured update that aims to preserve quality of service for the vast majority of users while acknowledging that a small segment of devices cannot sustain the new software features without compromising the experience.
Security patches and ongoing support for legacy devices
Despite the retirement of iOS 26 on two iPhone models and one iPad, Apple continues its standard practice of providing security updates for dispatched devices for a period after their main OS support ends. The company historically offers security-only patches for older devices for a year or two beyond the conclusion of active OS updates. This approach is not always accompanied by explicit, published timelines, and Apple does not always provide the same level of transparency as it does for Macs with security updates. The practical takeaway is that those older devices can still receive critical security protections for a window of time, albeit with less predictability than the main OS lifecycle.
For users who remain on XR, XS, or the 7th-generation iPad, this policy means there is potential to continue receiving essential protections even after iOS 26 or iPadOS 26 reach end-of-life status for the devices. However, the cadence and scope of these patches may vary, and users should be prepared for possible gaps or delays in certain security updates. The absence of explicit, published replacement timelines emphasizes the importance of planning for a device upgrade when feasible, particularly for users who rely on sensitive personal data, enterprise applications, or devices integrated into critical workflows.
From Apple’s security engineering perspective, the goal remains to mitigate risks associated with legacy software while encouraging migration to supported hardware that can fully leverage the latest protections. Security patches on older devices help close known vulnerabilities, but they cannot address new threat surfaces that rely on modern hardware capabilities or updated kernel-level protections. For this reason, the company’s strategy typically favors guiding users toward supported devices that can receive comprehensive protection and compatibility with the latest app ecosystems.
For readers evaluating their options, two practical considerations emerge. First, if an older device is still in daily use, determine whether it’s eligible to upgrade to iOS 26 or iPadOS 26 and assess the value of the new features, security improvements, and performance gains. Second, evaluate whether continuing to use an older device is worthwhile given the potential for reduced support in the future. If your workflows depend on the most current security updates and ecosystem compatibility, planning a transition to a supported device is a prudent step.
In short, while Apple does not publish granular patch windows for every device after the main OS drop, the general pattern remains: security-focused updates continue for a period, but the long-term reliability of legacy devices on the latest software is not guaranteed. Users who prioritize security and feature parity will find a strong incentive to adopt supported devices, ensuring continued access to the newest protections and the broadest compatibility with apps and services.
