WhatsApp is raising its minimum system requirements for Apple devices, meaning owners of several older iPhones have until November 30, 2026, to update their software or lose access to the app. Meta has confirmed that the messaging platform will now require iOS 15.5 or later, a step up from the previous iOS 15.1 baseline.
The policy shift directly impacts users still relying on the iPhone 6s, iPhone 6s Plus, iPhone SE (1st generation), iPhone 7, and iPhone 7 Plus. Fortunately, no hardware is being permanently cut off this year. Because every device capable of running iOS 15.1 can also support iOS 15.5, users simply need to install the latest available patch - iOS 15.8.8 - to maintain full compatibility.
This transition is notably less severe than the company's previous purge. In June 2025, WhatsApp completely dropped support for the iPhone 5s, iPhone 6, and iPhone 6 Plus, as those devices maxed out at iOS 15.0, leaving affected users with only the web browser version as a workaround. Meta notes that it routinely reviews operating system support to phase out platforms with declining user bases and outdated security frameworks.
How to Update Your iPhone for WhatsApp
- Open the Settings app on your device.
- Navigate to General.
- Tap on Software Update and install the latest available version (iOS 15.8.8).
Anyone running an outdated version will receive in-app notifications reminding them to upgrade before the November deadline.
The Security Baseline Shift
Meta’s decision to bump the requirement to iOS 15.5 rather than dropping the iPhone 6s and iPhone 7 entirely highlights a strategic pivot in how the company handles legacy hardware. Instead of forcing hardware upgrades, Meta is enforcing a stricter security baseline. By pushing users toward iOS 15.8.8, WhatsApp ensures its massive user base in emerging markets - where these older models remain highly active - stays protected against recent vulnerabilities without losing access to essential communication tools.
This approach balances user retention with the necessary cryptographic standards required for modern end-to-end encryption. As older operating systems stop receiving critical security patches from Apple, maintaining compatibility becomes a liability for encrypted messaging apps. By drawing the line at iOS 15.5, Meta mitigates these risks while keeping millions of legacy devices connected.
