How to fix notifications not working on iPhone after iOS 17.5 update

Notifications play an essential role in our digital lives, keeping us informed about incoming messages, critical alerts, and updates from our favorite apps. However, for one reason or another, not every iPhone user is getting the full benefits of these useful communications.

If notifications are not working on your iPhone after updating to iOS 17.5, you’re not alone. This guide is here to help with some easy tweaks, useful hacks, and more.

12 Ways to fix iPhone notifications not working

Notifications not showing up on your iPhone? Unfortunately, it’s a fairly common issue. Thankfully, there are some simple solutions to fix the problem in no time.

1. Restart your iPhone

If your iPhone notifications aren’t working after installing iOS 17.5, force restarting the device can often be the quickest and easiest solution.

This process will essentially turn your iPhone off and on again, clearing out any temporary glitches that could be causing problems with app notifications.

To restart your iPhone 8 or newer, press and hold the volume up or volume down button on the left side and the power button on the right side until the slider appears, and drag it from right to left.

Almost all apps on iPhones need a stable internet connection to fetch new data and deliver notifications without any interruptions.

So, if your iOS 17 notifications are not working, make sure you’ve turned on cellular data or Wi-Fi and check for potential network-related issues. Open Safari or a browser of your choice and head to a website like If you don’t see any issues, move onto the next solution.

If you’re unsure, you can always turn on Airplane mode, then turn it off after 30 seconds or restart your wireless router if you’re connected over Wi-Fi.

3. Ensure Focus Mode is turned off

Focus Mode can silence notifications, even when you’re not actively using it.

If you’re not receiving notifications after updating to iOS 17.5, check if Focus Mode is enabled. Turn it off to ensure all notifications are delivered without fail.

  1. Open the Control Center → Tap and hold Focus.
    Focus is replaced by the name of the Focus Mode that’s active.
  2. Select a Focus Mode you want to turn off. Once you turn off a Focus, all banners will go from white to grey.

    enabling Focus Mode on iPhone

Once you deactivate Focus Mode on your iPhone, you should deactivate automatic activation to ensure Focus Mode isn’t enabled automatically.

  1. Open the Control Centre → Tap and hold Focus.
    Focus is replaced by the name of the Focus Mode that’s active.
  2. Tap the three-dot menu next to the Focus Mode → Select Settings.

  3. Select Smart Activation or Custom Schedule → Tap Delete Schedule.


Once the Focus is turned off, ask your friends or family to send you a text to check whether you received the notification or not.

4. Turn off Share Across Devices

One of the many great features of Focus is that you can enable it across all Apple ecosystems. But what if you want the Focus on your Mac/iPad but not on your iPhone?

  1. Go to SettingsFocus.
  2. Toggle off the switch next to Share Across Devices.


And just like that, all our Focus-related escapades are done. Now, it is time to hop on to the Notifications section.

5. Ensure app notifications are enabled on iPhone

If you’re not getting notifications for specific apps on your iPhone, it’s probably because you haven’t allowed the app to send you notifications. To check:

  1. Go to Settings → Notifications → Select an app that’s facing issues.
  2. Toggle on Allow Notifications and Time Sensitive Notifications.
  3. Choose any alerts and banner style → Toggle on Sound.

    Check if Instagram notifications are enabled

6. Check in-app notification settings on iPhone

Even if you’ve enabled notifications for an app in your iPhone settings, there might be another layer of control within the app.

Many apps offer their own notification settings, so you can fine-tune how and when you receive alerts. Tweaking these in-app settings can often help you fix iPhone notifications.

For example, you can go to WhatsAppSettingsNotifications and adjust settings as per your preference. Likewise, you can make changes to other apps you use regularly.

If you’re still not getting notifications on your iPhone, it may be because of the Scheduled Summary setting.

7. Turn off Notification summary

Although the Scheduled Summary feature on iPhone can help you manage notifications easily without getting overloaded, it can inadvertently silence alerts you need to see immediately.

Therefore, you should check if turning off Scheduled Summary fixes your iOS 17 notifications.

  1. Go to Settings → Notifications.
  2. Tap Scheduled Summary.
  3. Toggle off Schedule Summary


8. Turn off Low Power and Low Data Mode on iPhone

While these modes are useful, they are known to restrict background app refresh on your iPhone. This can cause notifications to be delayed or not delivered.

  • To toggle off Low Power Mode:
    • Go to Settings → Battery → Toggle off Low Power Mode.

      To toggle off Low Power Mode
  • To toggle off Low Data Mode for Cellular:
    • Go to Settings → Cellular → Cellular Data Options.
      If you use dual SIMs, select a SIM to locate Cellular Data Options.

      Go to Cellular Data Options from Cellular in Settings
    • Tap Data Mode → Deselect Low Data Mode.

      Tap Data Mode and Deselect Low Data Mode.
  • To disable Low Data Mode for Wi-Fi:
    • Navigate to Settings → Wi-Fi.
    • Tap the blue ‘i’ icon next to a network → Turn off Low Data Mode.

      Toggle off Low Data Mode

9. Enable Background App refresh

If background app refresh is disabled for an app, it might be unable to deliver notifications.

Many iPhone apps rely on background app refresh to stay up-to-date and deliver timely notifications. So, do the following to check if this setting is enabled:

  1. Locate and open the Settings app on your iPhone or iPad.
  2. Navigate to General → Background App Refresh.

  3. Tap Background App Refresh → Select Wi-Fi & Cellular Data.
  4. Go Back and enable the toggle next to the apps you use.


10. Install latest iOS update

Many iPhone users have reported bugs with iOS 17.5 notifications.

If it is indeed a software glitch, Apple will soon fix it with a software update. So, install the latest iOS version as soon as Apple releases it. This will ensure you have the latest bug fixes and other refinements.

  1. Navigate to Settings → General → Software Update.
  2. Tap Update Now if a software update is available.

    Click on Update now for Software Update

11. Reset all settings on your iPhone 

If you’ve tried all the above troubleshooting tips and the iPhone notifications are still acting up, you may have to Reset All Settings.

This will revert your iPhone’s settings to the factory defaults, potentially eliminating any underlying issues to fix notifications not working after updating to iOS 17.5.

Note This will NOT delete any photos, videos, or files saved to your iPhone. It will, however, reset your wallpaper to the default background and erase your PIN password to access the phone.
  1. Go to Settings → General → Transfer or Reset iPhone.

    Go to Settings then General Transfer or Reset iPhone
  2. Tap Reset → Reset All Settings.
  3. Enter your iPhone or iPad’s Passcode.

    Tap Reset then Transfer or Reset iPhone
  4. Tap Reset All Settings again to complete the process.

12. Contact Apple for technical support

If you’ve tried all the solutions to this point and your iPhone notifications still aren’t working in iOS 17.5, the next best step is to contact Apple Support directly. They have a team of trained technicians who can help you diagnose and fix the issue.
