Why WhatsApp doesn’t show notifications on Xiaomi smartphones: a full fix guide

Introduction: Why WhatsApp notifications on Xiaomi are missing

Did you notice that WhatsApp stopped sending notifications to your Xiaomi Redmi, Poco or Mi 11/12/13, even though the messages are coming? This problem is familiar to millions of MIUI users - and it's not just the messaging settings that are to blame, it's the aggressive optimization of the battery, the peculiarities of the background processes and even the errors of the Meta servers. 80% of the time, the problem is solved in 5 minutes, but you need to know exactly where the switches are hidden.

In this article, we’ll look at all the possible reasons for not notifying WhatsApp on Xiaomi, from basic app settings to hidden MIUI options that aren’t even mentioned in the official documentation. You’ll learn how to check push services, why battery optimization blocks background activity, and what to do if notifications come with a delay of several hours, and why the problem is more common on models with MIUI 13/14 and how this relates to Google’s energy saving policy.

Spoiler: 95 percent of the time, it's not the software, it's the settings. And no, reinstallation of WhatsApp only helps in 1 in 10 cases. Let's get this straight.

1. MIUI battery optimization is the main enemy of notifications

The first and most common reason is automatic battery optimization in MIUI. By default, the system limits the background activity of applications to save charge. WhatsApp falls under this ban more often than others due to the peculiarities of its services, as a result of which notifications either do not arrive at all or appear with a delay of 1-3 hours.

How to fix it:

• 🔋 Open the Settings. → Annexes → Application management → WhatsApp
• 🔄 Click Battery Optimization and select Without Limits
• 📱 Turn on the AutoStart switch (this will allow WhatsApp to work in the background)
• 🔒 In the Permissions section, make sure Notifications and Background Activity are included.

Important: on some firmware (e.g. MIUI 14 Global), Battery Optimization may be called Energy Saving or Power Management. If you don't find it, search by settings (the magnifying glass icon in the upper right corner).

2. Notification settings in WhatsApp itself

Sometimes the problem isn't with the system, but with the settings of the messenger itself. WhatsApp has separate options for notifications that can get lost after updating or resetting settings. For example, if you once turned off the sound for a particular chat, this could extend to all notifications.

Check the following:

• 🔔 In WhatsApp itself: ⚙️ Settings → Notifications → Make sure all switches are on
• 🎵 In the Notification Tones section, select any sound (even if you don't need the sound, the system can block the vibration)
• 📌 In the settings of a specific chat (open the dialogue) → name → No sound - must be off
• 🌐 If you use WhatsApp Business, check your settings in Business Tools → Notifications

Pay special attention to Show Notifications, which may be hidden under additional settings on some versions of MIUI, and if this option is disabled, WhatsApp will not be able to send push messages even when the system permissions are enabled.

3.Problems with Google Play Services and push services

WhatsApp uses Google Play Services to deliver push notifications, and if the service is not working properly (for example, due to an outdated version or conflict with MIUI), notifications may not come at all, a problem that is especially relevant for devices without Google services (for example, Xiaomi for the Chinese market) or after manual removal of GMS.

How to check and correct:

1. Open Settings → Applications → App Management and search for Google Play Services.
2. Click Warehouse → Clear the cache (not data!).
3. Update your services through the Play Store (if available).
4. Reboot the phone.

If you MIUI Without Google (like firmware for China), WhatsApp notifications can come through alternative channels but with a delay (APK-file from APKMirror site or use of WhatsApp Web in browser.

4. Conflict with energy saving and “Do Not Disturb” modes

MIUI has several energy saving levels that can block notifications:

• 🔋 Super energy saving – disables background activity of all applications except system.
• 🌙 Do not disturb – can be turned on on on schedule or manually.
• 📵 Flight mode (sometimes switched on automatically when signal is weak).

How to check:

1. Open the notification bar and make sure the Do Not Disturb (moon) icon is not active.
2. Go to Settings → Battery and Performance → Power Saving Modes and turn off all restrictions.
3. Check Settings → Sound and vibration → Do not disturb → Schedule – it is possible that the mode is activated automatically.

Some models (such as the Redmi Note 10 Pro) have a hidden Night Mode Optimization setting that blocks notifications from 23:00 to 7:00. To turn it off, type in the “Night Mode” search for settings.

💡

If notifications only disappear at night, check the Sleep Mode settings in MIUI. It can automatically limit background activity after 1 hour of inactivity.

5. WhatsApp server errors or internet problems

Sometimes the problem isn't the phone, but the server side of Meta. WhatsApp may temporarily not deliver notifications because of:

• 🌍 Regional restrictions (e.g. traffic blocking in some countries).
• 🔄 Server updates (usually 1-2 hours).
• 📡 Problems with connecting to Google push servers (relevant for devices with custom firmware).

How to check:

1. Open Downdetector and see if there are mass notification complaints.
2. Try connecting to another network (mobile internet instead of Wi-Fi or vice versa).
3. If you use a VPN, turn it off – some servers block notifications when a VPN is detected.

If the problem is in the servers, you can only wait, but 90 percent of the time it's the phone, not WhatsApp, to make sure you check if the notifications are coming from other messengers (like Telegram or Viber), and if so, the problem is exactly WhatsApp or MIUI settings.

6. Resetting settings and extreme measures

If none of the above has worked, there are radical methods, but before you resort to them, make sure that:

• 📱 You have updated WhatsApp to the latest version (sometimes bugs are fixed in new releases).
• 🔄 Rebooted the phone (yes, it helps more often than you think).
• 🔍 Checked whether the notifications block third-party software (antiviruses, memory cleaners).

If the problem persists, try:

1. Reset WhatsApp Settings: Settings → Apps → WhatsApp → Storage → Clear Data (Warning: This Will Delete Chat History!).
2. Delete and reinstall WhatsApp (before doing so, back up the chats in Settings → Chat → Backup).
3. Reset network settings: Settings → SIM-maps and mobile networks → Resetting network settings.
4. Update MIUI (sometimes bugs with notifications are fixed in new firmware versions).

💡

Before you reset WhatsApp, make sure to back up! Without it, you'll lose your entire message history.

⚠️ Note: If you use custom firmware (like LineageOS or Pixel Experience), the problem may be the lack of proprietary push notification libraries. MIUI or GApps hand-held firmware.

7. Features for specific Xiaomi models

Some Xiaomi models have unique notification bugs:

• Redmi Note 10/11: Google's Microphone issue that conflicts with WhatsApp.The solution is to turn off the microphone in Google's settings.
• Poco X3/X4: Adaptive battery bug that blocks background processes, so the solution is to turn off adaptive optimization.
• Mi 11/12 Ultra: conflict with Dual Apps (if WhatsApp is duplicated) The solution is to remove the duplicate.
• Xiaomi for China: no Google Play Services, the solution is to manually install GMS or use alternative clients (like WhatsApp FM).

If you have one of these models, check the settings specific to it first. For example, Poco F3 has a hidden Game Turbo mode that can block notifications even outside of games. To turn it off, go to Settings → Special Features → Game Turbo and deactivate the option.

For Xiaomi 13/13 Pro with MIUI 14, the real-time resolution problem is relevant.

1. Go to Settings → Privacy → Special Access → Access to Notifications.
2. Find WhatsApp and turn on all permissions.
3. Return to Special Access → Real-time permissions and also turn on for WhatsApp.
