In a move that has sent shockwaves across the tech community and among loyal Apple users, WhatsApp has officially announced it will no longer support iPhones running on iOS versions below 15.1. This decision, which comes into effect immediately, means that popular models such as the iPhone 5s, iPhone 6, and iPhone 6 Plus are now unable to access or operate the messaging platform. For many users around the world still holding onto these older devices, this change marks the end of an era—and potentially the start of a scramble for new phones.

WhatsApp, owned by Meta Platforms, is one of the world’s most widely used messaging applications, boasting over two billion users globally. It has long been praised for its inclusive support across various devices and operating systems, but as technology advances and security requirements increase, the company is drawing a line to phase out older systems that no longer meet its standards. The move is being framed as a necessary step to ensure optimal functionality, data protection, and user experience.

The immediate victims of this decision are users of the iPhone 5s, iPhone 6, and iPhone 6 Plus—devices once hailed as flagship innovations but now deemed technologically outdated in the fast-paced smartphone industry. These models, launched between 2013 and 2014, cannot be updated beyond iOS 12.5.7, leaving them incompatible with WhatsApp's new minimum requirement of iOS 15.1. As a result, users with these devices can no longer send or receive messages, view status updates, or access their chats on WhatsApp unless they switch to a newer phone.

WhatsApp had hinted at this transition in previous updates, periodically reminding users to update their operating systems to continue enjoying full functionality. However, the sudden enforcement of this new requirement has caught many off-guard, especially in regions where older iPhones remain widely used due to affordability and reliability.

The company clarified that the decision was made in line with industry practices and was necessary for maintaining performance and security standards. According to WhatsApp’s official statement, “To keep our app running smoothly and securely, we routinely stop supporting older operating systems that no longer receive updates from Apple. We encourage users to upgrade to a supported device and OS version to continue using WhatsApp.”

For many users, this announcement feels like a forced migration, especially in developing countries where upgrading a smartphone is a costly affair. The iPhone 5s, 6, and 6 Plus, despite being several generations behind, are still commonly in use thanks to their durable design and sufficient functionality for everyday communication tasks. WhatsApp's new policy, however, renders them effectively obsolete for millions who rely on the app for daily communication, business transactions, and social interactions.

Social media has erupted with reactions from affected users, with many expressing frustration, confusion, and disappointment. Some users have taken to Twitter and Instagram to vent their concerns, with posts ranging from nostalgic tributes to their aging devices to urgent pleas for affordable upgrade options. One user tweeted, “My iPhone 6 has been loyal for years—never failed me once. Now I can't even send a ‘hello’ on WhatsApp? This is heartbreaking.”

Meanwhile, tech experts and analysts view this change as part of a broader trend in the tech industry where companies are gradually phasing out support for legacy systems to streamline performance, reduce security vulnerabilities, and push users toward more recent hardware. It’s a practical, albeit painful, reality in a sector driven by rapid innovation and evolving user demands.

Apple, for its part, had already ended software support for the affected models, meaning they no longer receive critical security patches or performance improvements. That reality has now caught up with WhatsApp users, as the app’s reliance on newer operating system capabilities leaves these older devices behind.

For those still clinging to their iPhone 5s, 6, or 6 Plus, the only solution is to upgrade to a newer model capable of running at least iOS 15.1. This includes devices like the iPhone 6s and above, which are still compatible with the latest iOS updates. While this may sound straightforward for some, it poses a challenge for users in lower-income brackets or those who simply prefer their older devices for reasons of simplicity or nostalgia.

Retailers and online marketplaces may see a sudden spike in demand for refurbished iPhones that support the new requirements, and some are already taking advantage of the situation by promoting trade-in programs or offering discounts on newer models. Apple’s official trade-in program allows users to exchange older models for credit toward a new purchase, though the amount offered for a 5s or 6 is minimal at best.

In the coming weeks, WhatsApp may also roll out additional prompts warning users on unsupported devices of the changes, and advising them on how to preserve their chat history when transitioning to a new device. The company offers cloud backup solutions through iCloud, allowing users to migrate their chat data to newer phones with minimal hassle—if they’re able to make the switch.

The decision underscores the tension between innovation and accessibility. While WhatsApp continues to push for technological advancement, millions of users are left at a crossroads, facing the difficult choice between upgrading or disconnecting. It's a stark reminder that in the digital age, staying connected often comes at a cost—and sometimes, that cost is your old, trusted phone.

As the world becomes increasingly dependent on real-time communication and digital tools, even the most loyal devices can suddenly become relics of the past. For WhatsApp users on unsupported iPhones, the message is loud and clear: upgrade, or log off.
