If you experience delayed notifications on your iPhone, it undermines the purpose of using real-time alerts. This might cause you to miss important meeting information, crucial messages, or upcoming events, such as the potluck next week. To address this issue before it becomes problematic, you can follow the simple tips provided below to fix delayed notifications on your iPhone. Instead of spending time and facing inconvenience by opening the app to check for new messages and updates, these tricks will help you troubleshoot delayed notifications on your iPhone.

#1 Turn Off Notification Summary

In iOS 15, Apple brought in a new feature called Notification Summary. When you activate it, apps on your iPhone won’t send notifications immediately. They will be scheduled to appear at a specific time later in the day. So, make sure you disable the notification summary to receive notifications as they arrive. To disable it, open the Settings menu, navigate to Notifications, tap on Schedule Summary, and turn it off from there.

#2 Clean the Device

One of the reasons why I am receiving text messages on my iPhone is cache clutter. The second reason is a lack of memory, which prevents applications and the smartphone itself from working effectively. You can optimize your device with a clean-up app for iPhone. With the phone cleaner app you can remove duplicate files, similar images and videos, organize contacts, etc. You can click here for info and read reviews. Among cleanup app reviews, additional features are often lost, such as a protected section, and a photo and video compression tool. CleanUp has a great chance of fixing delayed iPhone notifications and speeding up the device as a whole.

#3 Disable Focus Mode

Apple’s Focus feature serves as their version of the do not disturb (DND) function on iPhones. If you enable Focus, iOS will halt all notifications on your iPhone. You need to disable Focus or exclude your preferred apps from it.

To disable Focus:

  1. Swipe down from the top-right corner if you have an iPhone X or newer, or swipe up from the bottom if you have an iPhone with a Home button to open the Control Center.
  2. Turn off Focus.

#4 Turn on Notifications

To enable Notification Preview and configure Notification Styles, follow these steps:

  1. Open Settings.
  2. Tap on Notifications.
  3. Choose Show Previews and select either “Always” or “When Unlocked”.
  4. Select Show Previews on iPhone.
  5. Tap on <Notifications at the top left to go back.
  6. Scroll down to locate the app causing delayed notifications.
  7. Once found, toggle on Allow Notifications and select the preferred alert style.

#5 Turn Off Low Data Mode

You can prevent an app from using the internet in the background by enabling the Data Saver feature on your iPhone. If you’re using your iPhone in low-data mode, it can also lead to delayed notification issues. If you want to disable Low Data Mode on Wi-Fi, follow these steps: Go to Settings, then tap on Wi-Fi. Find your Wi-Fi network, tap on the info icon next to it, and turn off Low Data Mode. Similarly, if you’re using mobile data, go to Settings, then tap on Mobile Data. Tap on Mobile Data Options and toggle off Low Data Mode.

#6 Reset Network Settings

Removing all the network options saved on your iPhone can be a bit of a hassle. After all, you’ll have to add them again. That’s because resetting network settings on your iPhone removes all Wi-Fi and Bluetooth preferences. However, setting it up again won’t take long.

To reset the network settings on your iPhone:

  1. Open the Settings app on your iPhone and go to the General menu.
  2. Select ‘Transfer or Reset iPhone.’
  3. Tap on Reset and choose Reset Network Settings.
  4. If you’ve set a PIN or password, your iPhone may prompt you to enter it.


#7 Disable Low Power Mode

To prevent apps from running in the background and draining your battery, enable Low Power Mode. However, keep in mind that by preserving battery life, you might miss out on timely notifications from background apps. To disable Low Power Mode and receive notifications as usual, follow these steps:

  1. Open the Settings menu.
  2. Navigate to the Battery settings.
  3. Toggle off Low Power Mode.


The delay in receiving notifications is a software issue. This shouldn’t even be called a problem, since you simply have the wrong mode activated or notifications are disabled. In any case, the listed actions should help restore instant receipt of notifications from various iPhone services and applications.
