Part 1. Why My iPhone Notifications Delayed After iOS 18.1 Update?

Apple Intelligence and Summarize Previews issues

If you have Apple Intelligence on your iPhone, you should let Apple Intelligence work with the Summarize Previews feature to get instant notifications on iOS 18.1.

Network Issues

Updates can occasionally disrupt saved network preferences, potentially affecting apps that rely on network connections to deliver notifications. Resetting network settings or reconnecting to Wi-Fi can sometimes resolve this.

Focus Mode and Notification Settings

iOS updates can sometimes reset Focus Mode or notification preferences. This can result in notifications being paused or delayed if certain apps aren’t allowed under Focus settings.

Software Bugs

New iOS versions can come with bugs that impact system processes, including notifications. Apple typically releases updates to address these issues, so keep an eye out for further updates.

Low Power Mode

Low Power Mode limits background processes to save battery, which may delay notifications.

Part 2. How to Fix Notifications Delayed on iOS 18.1

Although it is tough to find the accurate causes, it is possible to solve it by trying possible solutions like the following list. Keep patient and get your instant notification now!

Fix 1. Turn Off Apple Intelligence or Turn On Summarize Preview

According to the feedback of iOS 18.1 users who encountered similar problems, you can stop the delayed notification by turning off your Apple Intelligence or turning on the Summarize Preview feature.

How to Turn on/off Apple Intelligence？

Step 1: Go to the Settings app on your iPhone.

Step 2: Tap Apple Intelligence & Siri.

How to turn on Summarize Preview？

Step 1: Enter the Settings application.

Step 2: Select Notifications > Summarize Preview.

Step 3: Find the app you get delayed notifications from the list and toggle on the button next to it.

Fix 2. Check Network Connection

If the problem is still not solved, try the later methods. Notifications, especially for apps like messaging or email, rely on a strong network connection. Weak or unstable connections may cause delays. You can try these steps to adjust your network connection.

Step 1: If you’re on Wi-Fi, try switching to cellular data and vice versa to see if notifications come in faster on one or the other.

Step 2: You can toggle Airplane Mode on and off to quickly reset your network connection.

Step 3: Make sure your Wi-Fi or cellular signal strength is strong, as weak signals can delay notifications.

Fix 3. Check Notification Settings for Each App

Make sure notifications are enabled for each app experiencing delays.

Step 1: Go to Settings > Notifications and select the app experiencing issues.

Step 2: Ensure Allow Notifications is on. After that, set Alerts to appear in all locations (Lock Screen, Notification Center, and Banners). In addition, if you rely on audible alerts or badge icons, you should ensure Sounds and Badges. Look for an Immediate Delivery option if the app has one, as this ensures notifications are delivered without delay.

Fix 4. Restart Your Device

Sometimes, system glitches can impact notifications. A restart can often clear up these issues.

Step 1: Hold the power button until you see the “slide to power off” slider.

Step 2: Slide to power off, then wait a few seconds before turning your device back on.

Fix 5. Update Apps

Outdated apps may not be fully compatible with the latest iOS version, which can lead to notification delays. To update apps, you just need to open the App Store, tap on your profile picture in the upper right corner, and scroll down to check for available updates.

Fix 6. Check and Adjust Focus Mode

Focus Modes, including Do Not Disturb, can affect notifications, potentially delaying or blocking them.

Step 1: Open Settings > Focus, and check each Focus Mode that might be active.

Step 2: Make sure the apps you want notifications from are included in the Allowed Notifications list within each Focus mode.

Step 3: Temporarily disable Focus Modes to see if this improves notification timing.

Fix 7. Reinstall the Affected Apps

Logging out and back in or reinstalling an app can reset its connection to notification servers.

Step 1: Open the app, log out, and close the app completely (swipe up in the app switcher).

Step 2: Restart the app and log back in.

Step 3: If this doesn’t resolve the issue, delete and reinstall the app from the App Store.
