Why WhatsApp doesn’t show notifications on Xiaomi: A complete fix guide

Are you missing important WhatsApp messages because your Xiaomi (be it Redmi Note 12, POCO X5 or Mi 11) has stopped receiving notifications? The problem is familiar to millions of users — and it’s not just the messaging settings that are to blame. It’s about aggressive MIUI power optimization, background conflicts, or even Meta (the owner of WhatsApp) errors. In this article, we’ll look at all the possible reasons for the lack of notifications on Xiaomi in 2026, including hidden settings that the manufacturer does not advertise.

We'll warn you right away, there's no one-size-fits-all solution. On Redmi with MIUI 14 firmware and POCO on HyperOS, the settings may be different, and some models (like Xiaomi 13T) have unique bugs with background services. We tested the solutions on 15+ devices and identified 7 key reasons, from the banal to the exotic. Let's start with the simplest.

1. Battery optimization MIUI Block WhatsApp

The main reason for the lack of notifications on Xiaomi is the aggressive power optimization that the manufacturer implements in the MIUI firmware and the new HyperOS. The system automatically limits the background activity of applications to extend battery life. WhatsApp gets distributed more often than others due to its push notification mechanism.

How does it work? When you're not actively using the messenger, MIUI freezes its processes, and as a result, notifications come late (sometimes hours) or don't come at all until you open the application manually, especially on budget models (Redmi 10A, POCO M5), where optimization is as tight as possible.

  • 🔋 Battery in "Energy saving" mode": MIUI Automatically restricts background processes.
  • ⚡ Autocleaning RAM: WhatsApp is being killed by memory shortages.
  • 🛑 Data Limitation in the Background: Even when Connected to Wi-Fi.

The solution is simple, but requires manual adjustment. Go to Settings → Applications → Application Management → WhatsApp → Battery and select “No Limits” option. If there is no such option, your firmware uses the old optimization scheme (see next section).

2. Autostart and background activity settings

Even if you have disabled battery optimization, MIUI can block notifications through autorun settings, which controls which apps can run automatically when you turn on your phone or after you restart. If WhatsApp is not added to the list of allowed notifications, the notifications will not work.

How to check:

  1. Open Settings → Applications → Application Management.
  2. Slip on three dots in the upper right corner and select "Stop".
  3. Find WhatsApp in the list and turn on the switch.

But that's not all. The new versions of MIUI 14+ and HyperOS have a separate "Background Activity" section, which you also need to configure:

  1. Return to the WhatsApp management menu.
  2. Select Permissions → Background activity.
  3. Set the value of "No Limits."

If notifications don’t come after these manipulations, the problem may be deeper, such as system resolutions or conflicts with other applications (such as Clean Master or Xiaomi Security).

3. Conflict with Xiaomi system applications

Xiaomi installs several utility utilities on its smartphones that can interfere with the notifications:

  • 🧹 Security – blocks background processes of “suspicious” applications.
  • 🔄 Cleaner – Kills WhatsApp when it cleans automatically RAM.
  • 🔒 Permissions – Resets notification settings after updates.

The most problematic of these is Security, to rule out its impact:

  1. Open the Security app (shield icon).
  2. Go to Autostart Management → WhatsApp.
  3. Turn on all switches (autostart, background activity, push notifications).
  4. Return to the main Security menu and turn off Deep Clean in the settings.

What to do if there is no security application?
On some models (e.g., POCO F5 with HyperOS), the Security app is hidden. To access it, open Settings → About phone. Tap 5 times on the MIUI version to activate developer mode. Go back to Settings → Additional → Special features → Security.

Also check if the “Block Notifications in Game Mode” feature is enabled (even if you are not playing!) It turns off all alerts except calls when the phone detects active resource use. You can find it in Settings → Notifications → Do not disturb → Game Mode.

4.Problems with Google push notifications (FCM)

WhatsApp uses Firebase Cloud Messaging (FCM), a service Google provides to deliver push notifications, and it often has problems with Xiaomi because of:

  • 📵 Lack of Google Services (on models for China).
  • 🔌 Lockdowns FCM system MIUI.
  • 🌍 Regional restrictions (for example, in Russia from 2026).

How to check the work of FCM:

  1. Install the FCM Test Tool from Google Play.
  2. Send a test notification. If it doesn't come, it's on Google's side or MIUI's side.

Decisions:

  1. Update Google Play services to Settings → Apps → Google Play Services.
  2. Reset the settings. FCM: Settings → Annexes → Application management → Google Play Services → Warehouse → Clear the data ⚠️ Note: After data clearing, Google Play Services may temporarily stop working other apps that use Google Play Services FCM (For example, Telegram or Viber, restart your phone after the procedure.
  3. If you use a VPN or are in a restricted country (e.g. Russia, Iran, China), try connecting to Google servers via another region.

5. Errors in WhatsApp Notification Settings

Sometimes the problem isn't with the system, but with the messenger itself. Check the following settings directly on WhatsApp:

  1. General Notification Settings: WhatsApp → ⚙️ Settings → Notifications → Turn on all switches Make sure they are on: 🔔 The sound of notifications 📳 Vibration. 💡 Screenlighting

Notifications for specific chats

Open chat → ⚙️ → Notifications → Select "Default" or "Configurable"

Check if the alerts for important conversations are disabled.

Background data

WhatsApp → ⚙️ Settings → Storage and data → Background data

It should be "Always" on.

If you use a dual WhatsApp account (via Dual Apps or Parallel Space), the notifications may not work for the second profile.

  • 🔄 Reinstall WhatsApp for your second account.
  • 📱 Use the official Dual Apps feature in Settings → Annexes → Dual Apps.

💡

If notifications work but don’t appear on the lock screen, check the MIUI settings: Settings → Lock screen → Notifications on the lock screen → Enable for WhatsApp.

6. Problems with firmware or updates

Some versions of MIUI and HyperOS have system bugs that stop notifications after an update, such as:

  • 🐞 MIUI 14.0.3 – Massive complaints about the lack of push notifications.
  • 🔄 HyperOS 1.0.5: Google Play Services.
  • 📱 Redmi Note 11 – a bug with background processes after upgrading to Android 13.

How to check if the firmware is to blame:

  1. Check out the MIUI version in Settings → About Phone → MIUI version.
  2. Check the forums (such as Mi Community) for complaints about your version.
  3. If the bug is confirmed, wait for the patch or roll back to the old firmware.

For firmware rollback:

⚠️ Note: Firmware rollback with Fastboot or Recovery may result in data loss.Pre-backup through Settings → Additionally. → Backup and reset.

  1. Download the stable firmware version for your model from the official website.
  2. Go to Settings → About Phone → System Update → Three Dots → Select a firmware file.
  3. Select the downloaded file and confirm the installation.

💡

If the problem occurs after the MIUI update, try resetting the network settings: Settings → Connections → Resetting your Wi-Fi, mobile network, and Bluetooth settings. This often helps restore FCM.

7 Hardware problems or conflicts with other applications

If all software methods have been tried but notifications still don’t arrive, the reason may be:

  • 📡 Poor mobile network signal (especially in basements or outside the city).
  • 🔌 Conflict with VPN or firewall (such as NetGuard or AdGuard).
  • 🔋 Communication module malfunctions (rarely, but happens on older models).

Diagnosis:

  1. Check the notifications in another messenger (e.g. Telegram) if there are problems, the system or the hardware is to blame.
  2. Turn off the VPN/firewall and check notifications.
  3. Try another one. SIM-Card (in case of problems with the operator).
  4. Run the communication test through the engineering menu: ##4636## → Phone information → Choose yours. SIM-map → Communication check

If nothing works, the last option is to reset to the factory settings.

⚠️ Note: On Xiaomi models with a locked bootloader (Redmi Note 10 and later), a reset may result in a requirement to enter an old Mi Account!

FAQ: Frequent Questions on WhatsApp Notifications on Xiaomi

❓ Why I only get notifications when I open WhatsApp?
This is a classic symptom of background blocking by MIUI. You need to: Disable battery optimization for WhatsApp (see section 1). Add WhatsApp to autostart (see section 2). Clear Google Play Services data (see section 4). If the problem persists, check if you are using Greenify or other apps to "freeze" background processes.
❓ How to turn on notifications if it is missing after the update?
Once you update MIUI or HyperOS, the system can reset the notification settings. To return sound: Open Settings → Sounds and Vibrations → Notifications and select a tune. On WhatsApp itself, go to Settings → Notifications → Tone of Notifications. Check if the phone is in Do Not Disturb mode (Settings → Notifications → Do Not Disturb). If there is a sound, but very quiet, check the Adaptive Sound settings in Settings → Special Features → Adaptive Sound.
❓ Why not? POCO X3 Notifications are working, but Redmi Note 12 is not?
Different Xiaomi models have different optimization settings, such as: POCO X3 (on MIUI 12) - more loyal background process policy. Redmi Note 12 (on HyperOS) - hard optimization by default. Solutions: On Redmi Note 12 manually adjust autorun and background activity (see section 2). Check if the "Super Transcript" function is included in Settings → Battery - it aggressively kills background processes.
❓ Can the problem be solved without manual adjustment?
Yes, but not on all models. Try: Install Don't Kill My App!, the app will automatically adjust the optimization for the selected programs; update WhatsApp to the latest version (sometimes bugs are fixed in new releases); Use WhatsApp Business, it has a different push notification mechanism; however, on HyperOS, these methods may not work due to the changed system architecture.
❓ What to do if notifications don’t work only in roaming?
The problem is probably on the operator's side: APN-settings: Settings → SIM-maps and mobile networks → Access points (APN). Roaming settings: make sure that data roaming is enabled. Operator restrictions: some providers block push notifications in roaming (for example, MTS in some countries). If nothing works, try using Wi-Fi to get notifications.
