WhatsApp will terminate support for older iOS versions starting 30 November 2026, according to WABetaInfo. The affected versions include iOS 15.0, 15.1, 15.2, 15.3, and 15.4, while iPadOS 15.5 will also no longer be supported after the cutoff date.
The change will also extend to WhatsApp Business, which will follow the same end-of-support timeline. Users are advised to update their devices to a newer iOS version before the deadline to avoid disruptions in service.
In markets such as Malaysia, most iPhone users will still be able to continue using WhatsApp without needing to replace their devices, as existing hardware can typically be updated to a supported iOS version.
WhatsApp has historically maintained support for older operating systems to ensure broader accessibility. However, the platform notes that continued support for outdated versions places additional strain on development resources and can slow the rollout of new features. The decision to discontinue support is therefore aimed at improving app stability and enabling the introduction of new functionality.
79% of iPhone users now running iOS 26, data shows
According to data published by Apple, 79% of iPhones worldwide are currently running iOS 26. Meanwhile, 14% of devices remain on iOS 18, while the remaining 7% are operating on older versions.
Adoption is notably higher among newer devices, with 86% of iPhones released in the past four years already running iOS 26. The trend reflects the typical pattern of faster update adoption among recent hardware, as newer devices are more likely to support and install the latest operating system versions.
A similar pattern is observed in the iPad ecosystem, where 68% of devices run iPadOS 26, 17% remain on iPadOS 18, and 15% use older versions.
The widespread adoption of the latest operating systems also has implications for developers, as higher consolidation around newer versions simplifies app development and reduces the need for extensive legacy support.
In comparison, Android shows a more fragmented ecosystem, with around 54% of devices running Android 16, followed by 11% on Android 15, 10.72% on Android 14, and approximately 24% on older versions.
Experts continue to encourage users to keep their devices updated, noting that software updates typically include important security patches, performance improvements, and bug fixes that enhance overall device safety and functionality.
