Notifications on Xiaomi smartphones are one of the most common user complaints. Unlike devices on pure Android, firmware is a very common problem. MIUI It has unique alert management mechanisms that often confuse even experienced owners.

In this article, we’ll discuss 12 key reasons why notifications may not be coming to your Redmi, POCO Xiaomi, from simple setup errors to hidden power saving restrictions, you'll learn how to check Google Play Services, why MIUI Optimized blocks application background activity, and what to do if notifications arrive with a delay or disappear altogether after a system update.

Most notifications (especially from Facebook, Instagram, Gmail) are delivered via Firebase Cloud Messaging (FCM) — If it doesn't work properly, the alerts may be delayed or gone:

1. Open the Settings. → Annexes → All apps and find Google Play Services.

The Super Power Saving mode is particularly insidious, it completely blocks the background activity of all applications except system applications. If it is activated, you won't even get notifications from the system. SMS or calls in some messengers.

⚠️ Note: On some models (POCO F3, Redmi Note 10 Pro has a hidden setting MIUI Optimized, which override standard Android resolutions, and to turn it off, you need to activate the developer mode and in Settings. → For developers to find a point MIUI Optimization (can be called optimization) MIUI) Then you can restart the phone.

5. Failures after MIUI update

Updates MIUI Often interrupt notifications because of:

• 🔄 Reset application permissions (especially after major updates, for example, with MIUI 13 on MIUI 14).
• 🐛 Bugs in new firmware versions (for example, in the MIUI 15 had a problem with the delivery of notifications from VK Telegram).

Problems with specific applications

Some apps have their own nuances with notifications on Xiaomi, let’s consider the most common cases:

WhatsApp, Telegram, Viber

• 📱 In the settings MIUI: Settings → Annexes → [messenger] → Notifications – activate all categories (messages, groups, calls).

• 📱 In the application settings (Settings) → Annexes → [annex]) turn on Display notifications and background activity.

For Instagram and Facebook, also check the settings in the app itself: often notifications are disabled at the account level (e.g., in Settings). → Notifications → Push notifications).

7. Hardware problems and resetting settings

If all software methods have been tried, but notifications still don’t arrive, the problem may lie in:

• 📶 Unstable Internet connection: push notifications require a constant connection to the network. Check the operation of Wi-Fi and mobile Internet in the background.
• 🔋 Faulty battery: if the battery is severely worn out (capacity) < 70%, the phone can force the background processes to shut down.
• 📱 Communication module failure: rare, but it happens that notification problems are related to modem malfunction (especially after falls or moisture hits).

To rule out hardware problems:

1. Check the notifications in Safe Mode: 1. Press the power button. 2. Keep your finger on the "Stop" option until the "Safe Mode" window appears. 3. Confirm the reboot. If the notifications are running in Safe Mode, the problem is in one of the installed applications.
2. Perform a reset of network settings: Settings → Connections and sharing → Reset network settings This will clear saved Wi-Fi, Bluetooth and mobile settings.
3. In extreme cases, make a full reset (backup data is mandatory!): Settings → The phone. → Backup and reset → Resetting settings
