From November 30, 2026, WhatsApp on iPhone will only be supported on iOS 15.5 or newer. Open Settings, then General, then About, and read the iOS Version line. If it says 15.4 or lower, go back to General, tap Software Update and install what it offers before the month runs out.
That’s a two minute job for most people. The rest of this page sorts out which iPhones are really affected, because some headlines have been vaguer than WhatsApp’s own wording.
What WhatsApp has actually said
The Help Center page on supported operating systems lists iPhones running iOS 15.1 and newer, then adds one sentence: starting November 30, 2026, only iOS 15.5 and newer will be supported. Android is listed as OS 6.0 and newer. I read that page on November 12.
WABetaInfo reported the change back in June and says WhatsApp Business follows the same rule, since the two apps share a codebase. WhatsApp’s page explains the reasoning in general terms: each year it looks at the oldest operating systems with the fewest users, which may lack current security updates. It also promises an in app notice and a few reminders before support ends.
What it doesn’t spell out is the behaviour on the day itself. Does the app refuse to open on November 30, or does it just stop receiving updates? The help page only says “supported”. Treat any article that announces a hard shutdown as a guess. You don’t want to find out the hard way either way.
Which iPhones this touches
| iPhone | Newest iOS it can run | Where that leaves you |
|---|---|---|
| iPhone 5s, 6, 6 Plus | iOS 12.5.8 (January 26, 2026) | Already below the current iOS 15.1 minimum. This change isn’t what stops them. |
| iPhone 6s, 6s Plus, 7, 7 Plus, SE (1st generation) | iOS 15.8.8 (May 11, 2026) | Fine after you install 15.8.8. At risk if you’re sitting on an older 15.x release. |
| iPhone 8 and newer | iOS 16 or later | Not affected. |
Apple’s security releases page lists iOS 15.8.8 as available for the iPhone 6s, iPhone 7 and the first iPhone SE. So for those phones, “your iPhone is too old” is the wrong reading. The hardware reaches 15.8.8, which clears 15.5 with room to spare. Anyone on 15.1 to 15.4 simply hasn’t updated.
One outlet, Analytics Insight, named the same models as affected, but its article links no WhatsApp source. I’d go by WhatsApp and Apple instead.
Update in this order
- Back up your chats. In WhatsApp, go to Settings, Chats, Chat Backup, then Back Up Now.
- Plug the phone in and join a wireless network.
- Go to Settings, General, Software Update and install the newest iOS 15 release it offers.
- When the phone restarts, check Settings, General, About again. You want 15.5 or higher.
Older iPhones often have almost no free storage left, and the download can fail for that reason. Clear a few large videos, or update from a computer using Finder.
If the update won’t install
An iPhone 6s or 7 that refuses 15.8.8 after you’ve freed space is a tired phone. At that point a used iPhone 8 or newer is the sensible replacement, and it doesn’t need to be a new model. WhatsApp verifies by SMS or call, so your account follows your number to the new phone once you restore the backup.
If you’re on an iPhone 5s or 6, there’s no update path to speak of, and the replacement question is already settled.
Why 15.8.8 is only a pause
Updating buys you time, not a future. 15.8.8 is the newest release Apple lists for these phones, and they’ll stay on it. Because WhatsApp says it reviews its oldest supported systems every year, my guess is the floor rises again. That’s a prediction, not something WhatsApp has announced. If your daily phone is an iPhone 6s or 7, start pricing a replacement now, on your schedule instead of WhatsApp’s. Phones that stop getting patches are a security problem on their own; our November Android security patch guide covers the same issue on the other platform.
And since you’re checking your phone anyway, take a minute to learn how account takeovers work. Our guide on recovering a hacked WhatsApp account walks through it.
Common questions
Will WhatsApp delete my chats on November 30?
Nothing WhatsApp has published says so. Its help page only says that unsupported systems lose support, and that you’ll be warned inside the app. Still, run a chat backup first (WhatsApp Settings, Chats, Chat Backup, Back Up Now). It takes a minute and removes the worry.
Is an iPhone 7 affected?
Only if it’s still on an old iOS 15 release. Apple’s security releases page lists iOS 15.8.8 as available for the iPhone 7, so it can reach a version well above 15.5. Update it and you’re covered.
How do I check which iOS version my iPhone runs?
Open Settings, then General, then About, and read the iOS Version line. You need 15.5 or higher. Anything that starts with 16 or above is already fine.
Does the change apply to WhatsApp Business?
WABetaInfo says yes, because WhatsApp Business shares the same codebase. WhatsApp’s own help page doesn’t mention Business separately, so check the listed requirements in the app if you run it for work.
What about iPad and Android?
WhatsApp’s help page lists Android 6.0 and newer and announces no new Android cutoff in the same sentence as the iPhone change. WABetaInfo mentions iPadOS 15.5 in passing, but WhatsApp’s page only talks about iPhones, so I can’t give you a firm iPad answer.
My iPhone is stuck on iOS 12. Is there a workaround?
Not a reliable one. iPhone 5s, 6 and 6 Plus top out at iOS 12.5.8, which is already under WhatsApp’s current iOS 15.1 minimum. A newer iPhone is the realistic fix. Verification by SMS or call moves your account to the new phone, so back up first.
