WhatsApp Notifications Not Showing on iPhone
Short answer
Check Settings → Notifications → WhatsApp first — Allow Notifications on, with Lock Screen, Notification Centre and Banners all ticked. If those look right, the usual culprit is Notification Summary, which silently holds WhatsApp alerts until a scheduled delivery time. Remove WhatsApp from it, then check your Focus modes and WhatsApp's own in-app settings.

Someone tells you they messaged you two hours ago. You open WhatsApp and there it is — delivered, unread, and with no banner, no badge and no sound to show for it. The message arrived. The notification did not.
Almost every case comes down to one of six settings, and they sit in two different places: iOS controls whether the alert is allowed to appear at all, and WhatsApp controls what it contains. Work through them in the order below, because the first one that is wrong usually explains everything.
Start with iOS notification settings
Go to Settings → Notifications, scroll down to WhatsApp, and open it.
Allow Notifications must be on. If it is off, nothing else in this guide matters — turn it on and test immediately.
With it on, check the Alerts row underneath. Three options need to be ticked for notifications to behave the way most people expect:
| Setting | What it controls | If unticked |
|---|---|---|
| Lock Screen | Alerts on the locked screen | Nothing appears until you unlock |
| Notification Centre | The swipe-down history | Missed alerts cannot be found later |
| Banners | The pop-up while using the phone | Silent arrival while you are on the phone |
| Sounds | The audible alert | Visible but silent |
| Badges | The red count on the icon | No number on the app icon |
Also check Banner Style below. If it is set to Temporary, banners vanish after a few seconds — easy to miss, and often mistaken for not appearing at all. Persistent keeps them on screen until you act.
While you are on this screen, note the Announce Notifications and Notification Grouping entries. Grouping set to By App bundles several WhatsApp messages into one stack, which can look like only one message arrived.
The setting almost everyone misses
Still in Settings → Notifications, tap Scheduled Summary at the top.
Notification Summary is an iOS feature that holds non-urgent notifications and delivers them in a batch at times you choose — often 8am and 6pm by default. Apps included in it do not produce a banner or sound when a message arrives. They simply appear later, in a bundle.
This is the single most common cause of “my WhatsApp messages arrive hours late”, because it can be switched on during iPhone setup without any obvious prompt, and because the symptom looks exactly like a broken app rather than a deliberate delay.
- Tap Scheduled Summary.
- If the toggle at the top is on, scroll to Apps in Summary.
- Find WhatsApp and turn it off.
Alternatively turn Scheduled Summary off entirely if you do not use it. Either way, WhatsApp alerts resume arriving in real time straight away.
Check your Focus modes
Focus (the successor to Do Not Disturb) is the second most common cause, and the trickiest to diagnose because a Focus can activate automatically on a schedule, at a location, or when you open a particular app — so it may be running at times you do not associate with it.
Go to Settings → Focus. You will see Do Not Disturb, Sleep, Personal, Work and any custom modes you have made. Open each one that is in use and check two things:
- People. This controls which contacts can break through. If it is set to Allowed Notifications From a short list, messages from everyone else are silenced.
- Apps. Add WhatsApp to the allowed list so its notifications come through regardless of who sent them.
There is also a Silence Notifications From mode on newer iOS versions that inverts the logic — in that case make sure WhatsApp is not on the silenced list.
Two further Focus details worth knowing. Time Sensitive Notifications, when enabled for a Focus, lets apps mark certain alerts as urgent enough to break through; WhatsApp uses this for calls. And Share Across Devices means a Focus you enable on your Mac or iPad also silences your iPhone — which catches people out constantly.
The quickest check is the Control Centre. Swipe down from the top-right corner and look at the Focus tile. If it names an active mode, that is very likely your answer.
WhatsApp’s own notification settings
iOS decides whether an alert may appear. WhatsApp decides what goes in it, and has a separate set of switches that can silence things independently.
Open WhatsApp, then Settings → Notifications. You get separate sections for message notifications, group notifications and calls. Each has:
- Show Notifications — the master switch for that category.
- Sound — set to None silences them without removing the banner.
- Show Preview — turns the message text on or off in the alert. With it off you still get a notification, but it reads only “WhatsApp” with no content, which some people interpret as nothing arriving.
In-App Notifications further down controls banners while WhatsApp itself is open — relevant if your complaint is that you miss messages in other chats while reading one.
Per-chat mute
If notifications work for most chats but not one specific person or group, that chat is muted. Muting is per-chat, applies across your linked devices, and persists through reinstalls.
Open the chat, tap the contact or group name at the top, and look for Mute. Options are 8 hours, 1 week and Always. Turn it off, or set it to a shorter duration.
In the chat list, a muted conversation shows a small crossed-out bell icon beside its timestamp. Scanning that list is the fastest way to find everything you have muted and forgotten.
Background App Refresh and Low Power Mode
These two affect delivery quality rather than the notification itself, but they produce symptoms that look identical.
Background App Refresh is at Settings → General → Background App Refresh. Make sure the master switch is on and WhatsApp is enabled beneath it. Push notifications are delivered by Apple’s push service and do not strictly require it — but without it WhatsApp cannot fetch message content and media in the background, so previews and images lag behind the alert.
Low Power Mode (Settings → Battery) pauses Background App Refresh and throttles background activity to save battery. It does not block push notifications outright, but the combination of reduced background work and a delayed app wake-up frequently makes alerts feel late. If your phone enables it automatically at 20%, that explains why the problem seems to appear in the evening.
Related: check Settings → Apps → WhatsApp and confirm Cellular Data is allowed. On mobile data without it, nothing syncs until you reach Wi-Fi.
Things that are not the cause
“My phone is full.” Low storage does not block notifications. It can cause other problems, and what is taking up iPhone storage is worth reading separately, but it is not this.
“I need to reinstall WhatsApp.” Reinstalling restores from your most recent iCloud backup, so any messages since that backup are gone. It almost never fixes a notification problem, because the cause is nearly always an iOS setting that survives the reinstall anyway.
“WhatsApp is using too much space so it stopped working.” Storage size and notification delivery are unrelated systems. If WhatsApp has grown very large that is worth addressing on its own terms, but it is not why your banners stopped.
“It must be the network.” Push notifications are tiny and arrive over any working connection. If other apps notify normally, the network is fine. The Android equivalent of this problem has genuinely different causes — see Android notifications delayed or not showing if you are helping someone on that platform.
The last resort that usually works
If every setting above is correct and nothing arrives, the push token registered with Apple has likely gone stale. Forcing a re-registration takes thirty seconds:
- Settings → Notifications → WhatsApp, turn Allow Notifications off.
- Wait ten seconds.
- Turn it back on.
- Restart the iPhone — hold the side button and a volume button, slide to power off, then power on again.
Send yourself a test message from another device. If notifications from every app are missing rather than just WhatsApp, the problem is iOS-wide, and Settings → General → Transfer or Reset iPhone → Reset → Reset All Settings is the next step. That resets preferences and Wi-Fi passwords but keeps all your data and apps.
