What WhatsApp’s new cutoff means for older phones
WhatsApp support ending for older operating systems means the app will only run on devices that meet new minimum software versions, while phones stuck on outdated iOS or Android releases will stop receiving updates and may eventually lose access to core messaging features. Meta has confirmed that from September 8, 2026, WhatsApp will require at least Android 6.0, and from November 30, 2026, it will require iOS 15.5 or newer. Earlier iOS versions such as 15.0, 15.1, 15.2, 15.3, and 15.4 will no longer be supported after the iOS deadline. These changes follow Meta’s annual review of which operating systems still receive modern security patches and are widely used. For millions of people relying on older iPhone compatibility or aging Android phones, the new rules turn routine OS updates into a hard requirement rather than an optional upgrade.
Which iPhones are affected and how iOS 15.5 changes the rules
On Apple’s side, the key change is the new iOS 15.5 update requirement. WhatsApp will drop support for any iPhone running below iOS 15.5 from November 30, 2026, including devices still on iOS 15.0 through 15.4. Older models such as the iPhone 6s, 6s Plus, first‑generation iPhone SE, iPhone 7, and iPhone 7 Plus are directly affected, as many owners have not moved beyond early iOS 15 builds. The good news: these phones can all update to at least iOS 15.5, and in practice up to iOS 15.8.8, so they retain older iPhone compatibility as long as users install the latest software. According to Mashable, none of these iPhones are permanently losing WhatsApp support, unlike the iPhone 5s, iPhone 6, and iPhone 6 Plus, which were cut off earlier because they could not move past iOS 15.0.
Android 6 requirement: why some users may need new hardware
For Android owners, the transition is tougher. WhatsApp’s new Android 6 requirement raises the minimum version from Android 5.0 (Lollipop) to Android 6.0 (Marshmallow) starting September 8, 2026. While many recent phones already meet this bar, a large number of older or low‑cost models are still locked to Android 5.x and cannot install newer firmware. PCMag notes that Meta has effectively moved support forward by an entire Android generation, and some devices will never receive an official update. In those cases, users face a hard choice: keep a phone that can no longer run a fully supported version of WhatsApp, or upgrade to newer hardware that supports Android 6 or above. This makes WhatsApp support ending on legacy Android versions more disruptive than the iOS change, where every currently supported device can reach iOS 15.5.
How to check your OS version and update before the deadline
There is still time to prepare before WhatsApp enforces its new software limits. On iPhone, open Settings, tap General, then Software Update to see your current iOS version and install the latest release, aiming for at least iOS 15.5. On Android, open Settings and scroll to About phone to confirm which Android version you use. If it is below Android 6.0, go to Settings, then System, then Software updates to look for an upgrade. If there is no update available, your device likely cannot move beyond its current Android version, or it lacks enough free storage for the installation. Meta will also display in‑app reminders on affected phones, warning that support is changing and encouraging users to update before they lose compatibility.
Why WhatsApp is phasing out older iOS and Android versions
Meta says it reviews supported operating systems every year to keep WhatsApp aligned with modern security and performance standards. According to PCMag, the company “analyzes operating systems and drops support for the oldest ones with the fewest users.” Phones running very old iOS or Android releases often stop receiving core security patches from Apple or Google, and they may lack newer APIs that WhatsApp needs for features such as improved media handling or stronger encryption. Maintaining compatibility with those platforms also slows development, because engineers must work around missing functions and outdated libraries. By enforcing the iOS 15.5 update and the Android 6 requirement, WhatsApp concentrates its efforts on systems that can still be secured and updated, even though it means some users must update or replace their devices to stay connected.
