Why WhatsApp stopped working on Xiaomi Redmi smartphones: a full analysis of the causes and solutions

You open WhatsApp on your Xiaomi Redmi, and instead of a list of chats you see an endless load, a connection error or a blank screen? The problem is familiar to millions of users - according to Downdetector, messenger failures on Xiaomi devices are recorded 3 times more often than on other Android smartphones. The reasons lie not only in the application itself, but also in the features of MIUI firmware, background optimization and even hardware limitations of Redmi budget models.

In this article, we’ll not just list the standard tips like “reinstall the app” or “check the internet.” We’ll break down 10 unique reasons WhatsApp might not work on Xiaomi Redmi, from the hidden MIUI 14/15 settings to conflicts with Google Play Services. Each solution is tested on Redmi Note 12/11/10 Pro, Redmi 9A/9C and POCO X5 models in 2026. If you’ve tried the obvious methods, click through to the Deep System Bugs section.

1.Typical WhatsApp errors on Redmi: how to distinguish a system bug from account problems

The first thing to do is to diagnose the type of failure, and WhatsApp’s workflows on Xiaomi Redmi fall into 3 categories:

• 📱 Local – Related to device-specific settings (battery optimization, resolutions, cache).
• 🌍 Server-side problems (as signaled by status on Downdetector)
• 🔒 Account - number lock, use violation, two-factor authentication.

How do you know if your Redmi is the problem?

• ⚠️ The app works on other devices with the same number (check through the web version of web.whatsapp.com).
• ⚠️ The error only appears when you connect to the mobile Internet (and Wi-Fi is fine) – this indicates problems with the APN- settings of Xiaomi.
• ⚠️ WhatsApp crashes when you try to send media files — for Redmi models with 3/32 GB of memory, where the system kills background processes.

Critical: If you see a message that says, "Your account is temporarily blocked" when you start WhatsApp, the problem is not with your phone, but with breaking the rules of the service, in which case you need to contact Meta instead of digging into MIUI settings.

Background optimization MIUI: Why WhatsApp is “falling asleep” or not getting notifications

The main reason WhatsApp is no longer working on Xiaomi Redmi is the aggressive battery optimization in MIUI. Even in newer firmware versions (MIUI 14/15), the default system limits the background activity of applications to save charge.

• 🚫 No notifications for new messages (only come when the application is open).
• ⏳ Delayed delivery of messages up to 10-15 minutes.
• 🔄 Automatically log out of your account after hours of inactivity.

How to turn off optimization for WhatsApp:

1. Go to Settings → Applications → Application Management → WhatsApp.
2. Slip on "Battery Optimization" and select "No Limits".
3. Go back and turn on "Autostart" and "Background Activity".
4. In the Permissions section, make sure that Notifications, Storage and Microphone/Camera are included (if you use calls).

Turn off battery optimization |Enable autostart |Allow background activity |Check notification permissions-->

⚠️ Warning: On some Redmi models (e.g., Redmi 9A with MIUI 12.5), the Battery Optimization option may be called Energy Saving or Background Limitation. If you don't find the right section, search by settings (the magnifier icon at the top of the screen).

After the changes, reboot your phone, which will reset the MIUI services cache that handle background processes. If the notifications still don't come, check the sync settings:

1. Open Settings → Accounts and Sync → WhatsApp.
2. Make sure that the synchronization of "Contacts" and "Application Data" is enabled.

Lack of memory and cache: when WhatsApp “hangs” on the download screen

Xiaomi Redmi models with 32 GB of memory (for example, Redmi 10A or Redmi 9C) often face a problem: WhatsApp starts to slow down, does not open chats or even crashes when trying to send photos.

How to check:

• Open Settings → Storage and see how much space is free in the “Other” section (should be at least 1.5-2 GB).
• Go to Settings → Applications → WhatsApp → Storage and check the size of the “Cache” (if more than 500 MB – it’s time to clean).

Cleaning instructions:

Critical information for Redmi owners with 32 GB of memory: WhatsApp can automatically delete media files older than 30 days if the free space is less than 1 GB. To avoid this, transfer the WhatsApp/Media folder to the SD- card or to the cloud.

4.Network problems: Why WhatsApp doesn't connect to the internet on Redmi

If WhatsApp shows a “No Internet connection” error and other apps are working fine, the problem lies in the network settings.

• 📶 Incorrect APN- settings for mobile internet.
• 🔒 Block WhatsApp traffic in Traffic Savings.
• 🌐 Conflict with VPN or proxy (especially on MIUI Global for China).

How to set up an APN for WhatsApp:

1. Go to Settings. → SIM-maps and mobile networks → [Yours. SIM] → Access points (APN).
2. Click on the current profile and check the settings: Name: [your operator] APN: internet (or internet.[operator].ru) Proxy: not specified Port: no username/password: no authentication protocol: PAP or CHAP APN type: default,supl
3. Save the changes and restart the phone.

⚠️ Warning: On some firmware MIUI for Russia (e.g., on Redmi Note 11 with MIUI 13), the "Type APN" option must be default,supl,mms, otherwise MMS will not be sent (including WhatsApp stickers).

If the problem persists, check the Traffic Savings:

1. Open Settings → Connections and Sharing → Save Traffic
2. Make sure WhatsApp is not on the restricted app list.
3. Turn off the "Background Traffic Limitation" for the mobile network.

5. Conflicts with other apps: who prevents WhatsApp from working

On Xiaomi Redmi, WhatsApp can conflict with:

• 🛡️ Antivirus (Avast, 360 Security, built-in MIUI Security).
• 🔄 Clean Master, DU Speed Booster.
• 📱 Application Clones (the "Dual Applications" function in MIUI).
• 🔒 Ad-blocking applications (AdGuard, Blokada).

How to check:

1. Launch your phone in Safe Mode (press the power button → “Safe Mode”).
2. If WhatsApp is running in Safe Mode, the problem is in one of the installed apps.
3. Turn off antiviruses, cleaners and VPNs alternately, checking the messenger.

💡

If you use the dual apps feature for WhatsApp, make sure the clone has the same permissions as the main app. Often the clone works without notifications due to MIUI limitations.

Pay special attention to the built-in MIUI antivirus:

1. Open Security. → Antivirus.
2. Go to Settings (cog at the top) → Real-time Scan.
3. Add WhatsApp to the "Exceptions".

6. Deep system bugs: When firmware or iron is to blame

If none of the previous methods worked, the problem could be at the firmware or hardware level.Here are 3 hidden MIUI bugs that break WhatsApp:

How to check hardware limitations:

1. Open Settings → About Phone → MIUI version and check if the beta version of the firmware is installed (they often contain bugs).

💡

If your Redmi runs on MIUI China, WhatsApp may be blocked due to a lack of Google services, the solution being to flash the global version of MIUI or use Google Installer.

7. account problems: lock, two-factor authentication and number errors

Sometimes WhatsApp doesn't stop working because of your phone, but because of an account problem. Here are 4 signs that it's your number:

• 🔐 When you enter, you are asked to enter a two-factor PIN- code that you did not install.
• ⏳ The message "Wait X minutes before trying again" when sending the confirmation code.
• 🚫 Notice "Your account is temporarily blocked."
• 📱 The app asks you to confirm the number, although you haven't changed it.

What to do:

1. If you request a two-factor PIN but you haven't set it, try entering 123456 or leave the field blank. If it doesn't work, use the recovery form.
2. When blocking your account, check the email linked to WhatsApp – there should be a letter with instructions.
3. If the confirmation code doesn't arrive: Try requesting a voice call ("Send the code by calling"). Make sure the number isn't blocked by the operator for SMS (check the balance). Temporarily disable the antivirus or firewall - they can block SMS from WhatsApp.

⚠️ Warning: If you have recently changed SIM- card (e.g., from physical to eSIM), WhatsApp may require re-activation. In this case, link the number again via Settings → Account → Change number.

8. Alternative solutions: if nothing has worked

If WhatsApp still doesn’t work, try these non-standard methods:

• 🔄 Retract to older version: Sometimes new WhatsApp updates contain bugs for MIUI. Download APK version 2.23.17.78 (stable for Xiaomi) from Aptoide and install manually.
• 📱 Using WhatsApp Web: If the mobile app doesn’t work, log in via web.whatsapp.com to the Chrome browser on your phone (enable PC mode in site settings).
• 🛠️ Network reset: Go to Settings → System → Settings Reset → Network Reset. This will delete all stored Wi-Fi and APN, but often resolves connection issues.
• 🔧 Fastboot Firmware: If MIUI bugs are critical, run your phone through the Mi Flash Tool (instructions for Xiaomi.EU).

Last Chance: If WhatsApp doesn’t start even after reinstalling, check the integrity of your system files:

1. Install ADB Tools on your PC.
2. Connect Redmi to USB with debugging enabled (Settings → About Phone → MIUI Version → 7 times tap on version → return to Additional → For developers → Debugging by USB).
3. Enter the command: adb shell dumpsys package com.whatsapp If the output line is "codePath=/data/app/com.whatsapp-1/base.apk", the application is installed correctly. If there is no path - files are corrupted, you need a complete reinstallation.

💡

On Redmi models with a MediaTek processor (like the Redmi 9A), WhatsApp can slow down due to poor performance. Try turning off animations in Settings → Additional → For developers → Animation Scale (off).
