WhatsApp's November 30 iPhone Deadline: Check Your Version, Back Up Your Chats, and Stay Connected

AI-generated illustration of a smartphone showing a messaging app beside a wall calendar with a deadline circled.

WhatsApp is quietly raising the floor under its app, and for most people the change will pass unnoticed. For a smaller group of users on very old phones, though, it is the difference between chatting as normal and being locked out. Android phones running Android 5.0 or 5.1 already lost support on 8 September 2026. The next date to know is 30 November 2026, when the minimum requirement for iPhones rises from iOS 15.1 to iOS 15.5. If your phone is affected, the fix is usually a free software update — but only if you do it in time, and only if you back up your chats first.

This guide explains both deadlines, who actually needs to act, how to check your phone in under a minute, and what to do if your phone cannot be updated at all. One caution up front: WhatsApp sets its limits by operating-system version, not by phone model, so a list of phone names floating around online is never the final word. Your installed version is what counts.

The two deadlines at a glance

WhatsApp reviews the operating systems it supports from time to time and retires the oldest ones. Its stated reasoning is straightforward: the oldest devices tend to have the fewest users, may no longer receive the latest security updates, and may lack the functions newer versions of WhatsApp need. Two changes from its official supported-operating-systems information matter right now:

Android — already in effect. From 8 September 2026, WhatsApp supports Android 6.0 and newer only. Phones still running Android 5.0 or 5.1 no longer meet the requirement. This applies to both WhatsApp Messenger and WhatsApp Business.
iPhone — coming on 30 November 2026. From that date, WhatsApp will support only iOS 15.5 and newer on iPhones, up from the current minimum of iOS 15.1. If your iPhone is running iOS 15.1 to 15.4 on that date, it falls below the new floor.

WhatsApp says it notifies users in the app before support for their operating system ends, with reminders to update their software or move to a supported device. If you have seen such a warning, treat it as real and act on it rather than dismissing it. If you have not seen one, checking your version yourself takes less than a minute and removes all doubt.

Android: the September cutoff already happened

Android 5.0, known as Lollipop, was released in 2014, and Android 6.0 followed in 2015. That age is the point: a phone still running Android 5.0 or 5.1 in 2026 is running software that stopped receiving security patches years ago. WhatsApp's September cutoff therefore lands hardest on handsets that launched on Lollipop and never received a later official update from their manufacturer.

Here the distinction between version and model really matters. WhatsApp does not publish an official list of banned phone models, and coverage of the cutoff is careful to say the same thing: whether a particular handset is affected depends on the version of Android installed on it and on the updates its manufacturer made available. A phone that shipped with Android 5 but later received an official update to Android 6 or newer still meets the requirement. A phone stuck on 5.0 or 5.1 does not, and no update is coming for it now.

Reports of the cutoff commonly name older handsets that reached their software ceiling at Android 5.0 or 5.1, including the Samsung Galaxy S4 and Galaxy S3, the HTC One M7, the LG G2, the Sony Xperia Z, the first-generation Motorola Moto G, and the Google Nexus 4, along with budget models from several other makers. Treat that kind of list as examples from news coverage, not as an official WhatsApp list — and check your own phone's version rather than assuming anything from its name.

If your Android phone is still on 5.0 or 5.1, the honest answer is that no setting, reinstall, or workaround inside WhatsApp will restore support. Your options are to install an official manufacturer update if one exists for your device, or to move WhatsApp to a phone that runs Android 6.0 or newer. Any phone bought new today runs a far newer Android version, so a replacement does not need to be expensive or new — it only needs to be supported.

iPhone: the 30 November deadline is a software update, not a new phone

The iPhone deadline is much gentler, and that is worth saying plainly because alarming headlines can make it sound worse than it is. From 30 November 2026, WhatsApp will require iOS 15.5 or newer. The current minimum is iOS 15.1, so the change only bites if your iPhone is sitting on iOS 15.1, 15.2, 15.3 or 15.4 and you never update it.

Every iPhone that can run iOS 15 can also run iOS 15.5 or later. The models in this group are the iPhone 6s, iPhone 6s Plus, first-generation iPhone SE, iPhone 7 and iPhone 7 Plus. Apple released iOS 15.8.8 for those same models on 11 May 2026, which is well above the 15.5 floor WhatsApp will require. In practice, then, no iPhone that is currently supported by WhatsApp is blocked by its hardware from meeting the new requirement — anyone who loses access in November will have skipped the updates. Opening Settings, then General, then Software Update, and installing what is offered fixes it in a few minutes.

The iPhones that cannot reach iOS 15.5 at all — models such as the iPhone 6, iPhone 6 Plus and iPhone 5s — are already outside WhatsApp's current requirements, which have required iOS 15.1 or later. The November date changes nothing for them. If you are still using one of those phones for WhatsApp, you are already past the supported line, and moving to a newer phone is the only route back to a supported setup.

The new login check: what is reported, and what is not confirmed

Separate from the two published deadlines, there is a newer development that deserves careful wording. In early October 2026, the WhatsApp feature tracker WABetaInfo reported that WhatsApp had begun rolling out a server-side check that can block sign-in on devices running outdated operating systems that lack current security patches. Because it is delivered from WhatsApp's servers, it needs no WhatsApp app update to appear, and affected users reportedly cannot dismiss the warning and continue — they must update the phone's operating system before they can complete login.

Two limits on that report matter. First, the rollout is described as selective, reaching only some accounts and devices at first, so two people with similar phones may not see it at the same time. Second, WhatsApp has not publicly specified exactly which operating-system versions trigger this particular login check, and it has not announced a wider rollout. So treat the login check as a reported, limited rollout rather than a confirmed WhatsApp-wide change, and treat the published minimum versions — Android 6.0 now, iOS 15.5 from 30 November — as the firm, documented requirements. The practical lesson is the same either way: an up-to-date operating system is now part of staying signed in, not just part of getting new features.

How to check your phone in under a minute

On Android: open Settings, then look for About phone (on some phones it is under System, or labelled Software information). The Android version is shown there. If it says 6.0 or higher, you meet the current Android requirement. If it says 5.0 or 5.1, check for a manufacturer update under Settings, then System, then Software update — and if none is offered, your phone is at its ceiling.

On iPhone: open Settings, then General, then About, and look at the iOS version. If it says 15.5 or higher, you already meet the November requirement. If it says 15.1 to 15.4, go to Settings, then General, then Software Update, and install the update offered. If your iPhone cannot be updated past iOS 15 at all, it belongs to the older group already outside support.

Do this check on any phone you rely on for WhatsApp, including a second phone or a parent's phone that you help maintain. The people most likely to be caught out are not tech-news readers — they are people whose phones simply work, who never open the update screen, and who only discover the problem when a warning or a failed login appears.

Back up your chats before you change anything

Whether you are updating an iPhone or moving to a different phone, make a fresh chat backup first. A backup is what lets your message history survive the move; without one, switching phones can mean starting with an empty chat list.

On Android: in WhatsApp, go to Settings, then Chats, then Chat backup, and run a backup to Google Drive. Note the date and time shown for the last backup and make sure it is today, not months ago. Keep the phone on Wi-Fi and charging while a large backup runs.

On iPhone: in WhatsApp, go to Settings, then Chats, then Chat Backup, and run a backup to iCloud. Again, check that the last backup time is current. If your iCloud storage is full, the backup may silently fail, so free up space or check the backup size before you rely on it.

When you move to a new phone, install WhatsApp there, verify the same phone number, and restore from the backup when prompted — or use WhatsApp's built-in chat transfer from the old phone if both phones are in your hands. Do not delete WhatsApp from the old phone, and do not delete the old account, until you have opened the new phone and confirmed your chats are actually there. That one check prevents the most common moving-day loss.

What not to do

A support cutoff always attracts bad advice, so a few warnings are worth including. Do not download WhatsApp installation files from random websites promising to "unlock" or "restore" support on an old phone — unofficial builds can steal your account or your messages, and they cannot change your operating-system version anyway. Do not pay anyone offering to re-enable WhatsApp on an unsupported phone. Do not factory-reset an old phone hoping the reset will somehow bring a newer Android version with it; a reset only wipes your data and leaves the same old software behind. And do not trust a model list on social media as the final answer about your phone — check the version number on the phone itself.

One more thing people often ask: WhatsApp on a computer or a linked tablet is tied to your phone account, so it is not a substitute for a supported phone. If the phone itself falls out of support, the linked devices do not solve the problem. Keep the phone supported, and everything else follows.

Checklist: stay connected past 30 November

Check your version today: Android 6.0 or higher, or iOS 15.5 or higher, and you are fine.
iPhone on iOS 15.1 to 15.4: install the update from Settings, then General, then Software Update, before 30 November 2026.
Android on 5.0 or 5.1: look for an official manufacturer update; if none exists, plan a move to a supported phone.
Run a fresh chat backup (Google Drive on Android, iCloud on iPhone) and confirm the backup time is current.
If you move phones, verify the same number, restore the backup, and confirm your chats before wiping the old phone.
Do not sideload unofficial WhatsApp builds or pay for "unlock" services — neither can restore support.
Help family members check too: the people most at risk are those who never open the update screen.
After updating, open WhatsApp and send a test message to confirm everything works.

Bottom line

WhatsApp's 2026 support changes are a clean-up of decade-old software, not a reason to buy a flagship phone. Android 5.0 and 5.1 are already out, and iPhones need iOS 15.5 from 30 November 2026 — a bar every currently supported iPhone can already clear with a free update. Check your version now, update if one is offered, back up your chats before you switch anything, and you will stay connected without drama. If your phone genuinely cannot be updated, moving to any supported phone — new or second-hand — is the fix, and your backed-up chats will come with you.
