Why Notifications Are Coming to Xiaomi: The Complete Guide

A modern smartphone has become a central communication hub, and a missed message or call can be a serious problem. Owners of Xiaomi, Redmi and POCO devices often face aggressive optimization of the MIUI or HyperOS system. This feature is designed to save battery power, but often blocks the operation of messengers in the background, depriving the user of important information at the most inopportune moment.

When an application is only open and silent in the background, it requires a comprehensive approach to diagnosis, and most often it is not a hardware failure, but a software limitation set by the manufacturer by default, and understanding how security manages resources will help you regain control of notifications and customize the device to suit your needs.

In this article, we will look at all the possible causes of failures in detail and suggest step-by-step solutions. You do not need to be an expert in programming to fix this error, but rather check several settings consistently, which are often ignored by users when they first set up the gadget.

Impact of energy saving mode on application operation

The main culprit behind the lack of alerts is power saving algorithms. MIUI seeks to extend battery life by forcibly shutting down the background processes of applications you rarely use, which means that the messenger may simply not be able to start the process of obtaining data until you manually open it.

To solve this problem, you need to change the battery settings for each important application, the system needs to "understand" that a particular program is critical to you and cannot be stopped, and this is especially true for email clients, enterprise messengers and banking applications.

To allow an application to run in the background, find it in the list of installed programs and select Saving battery. Here you need to set the value No restrictions. This action will remove the lock from the background processes and allow the application to maintain a constant connection to the server.

  • πŸ”‹ Open the Settings menu and go to the Applications section.
  • πŸ”‹ Select a problem app from the list or find it through search.
  • πŸ”‹ Click on Autostart and turn on the switch.
  • πŸ”‹ In the charge saving section, select the option No restrictions.

πŸ’‘

Do not turn on the Superpower Saving mode on a permanent basis, as it blocks the work of most background processes, except for calls and SMS.

Configure notifications within MIUI and HyperOS

Even if the app is set up correctly, system filters can hide alerts. Xiaomi’s shells have a separate notification management center that takes precedence over the app’s settings. If it’s banned, no other action can help.

It's important to distinguish between "Important" and "Other" notification types. The system often defaults to sending messages from new applications to "Other" category, which do not make sound or vibrate, but just appear in the curtain. To fix this, you need to change priority.

⚠️ Warning: After a major system update, notification settings may reset to factory values. Always check this section after you change your Android version or MIUI.

Go to Settings β†’ Notifications and Control Center β†’ Application Notifications. Make sure the switch in front of the desired application is active. Also check if the Do Not Disturb or Only Important mode is on, which can filter incoming data.

  • πŸ”” Go to Settings. β†’ Notifications.
  • πŸ”” Find the desired application in the list.
  • πŸ”” Make sure the slider Allow notifications is enabled.
  • πŸ”” Check notification categories within the app (e.g., β€œMessages”, β€œCalls”) and set them a high priority.

πŸ’‘

The system notification filter in MIUI is of the highest priority and can block alerts even when you are actively setting up within the application itself.

Problems with network connection and background data transmission

Often the reason lies in the limitations of mobile network or Wi-Fi. If an application is forbidden to use the Internet in the background or save traffic, it will not be able to receive a new message until you open the screen.

Check traffic restriction settings. The system can block data transmission for certain applications when the screen is off. Also worth paying attention to the operation of Wi-Fi in sleep mode: some routers or phone settings can break the connection to save energy.

Features of 5G and traffic saving
With the traffic saving mode enabled, the system can force background synchronization to be turned off for all applications except for Google system services.

For diagnostics, try switching from Wi-Fi to mobile and vice versa. If the problem disappears when you change the connection type, it's the router or carrier settings, and make sure the application is allowed to use data in the background.

  • πŸ“Ά Open the Settings. β†’ Wi-Fi.
  • πŸ“Ά Click on the arrow next to your network name.
  • πŸ“Ά Make sure that the option to use Wi-Fi in sleep mode is set to Always".
  • πŸ“Ά Check the settings of the mobile network β†’ Save traffic and add exceptions for important apps.

Android Version Conflicts and MIUI Updates

After updating the operating system or MIUI shell, the old settings may conflict with the new security rules. Android 12, 13 and 14 have made major changes to how apps work in the background, requiring more explicit permissions from the user.

If the problem appeared immediately after the update, system permissions may have been lost, and new versions of HyperOS add additional layers of protection that may consider active background work of messengers as suspicious activity.

Android versionFeature of the workRecommended action
Android 11Basic background limitationsEnable autostart
Android 12/13Strict control of background activityAllow background activity manually
Android 14+Suspending rarely used applicationsDisable "Stop if not in use"

In new versions, the app has a function called "Stop Apps If They Are Not In Use." If you haven't opened a messenger in a long time, the system could automatically restrict its functionality, find the app in the settings and uncheck the corresponding item.

⚠️ Note: Resetting network settings may result in deleting saved Wi-Fi passwords. make sure to remember them before performing a reset.

Third-party cleaning applications and antiviruses

The accelerators, memory cleaners or third-party antiviruses you install can be more effective than the system itself in destroying background processes. They often perceive an active messenger connection as a threat or an unnecessary load on the battery and force the process to be terminated.

The standard Xiaomi security app is usually enough to protect the device. Installing additional aggressive optimizers creates a resource conflict. If you have Clean Master, Du Speed Booster or similar installed, try temporarily removing them and checking the notifications.

Why Antiviruses Block Notifications
Many antiviruses use heuristic analysis and block any background connections that are not labeled as β€œsystemic” or β€œtrusted,” especially at night.

Also check the settings of the built-in Security app itself. Deep cleaning features may be active in the Licenses or Settings section, which should be disabled for important programs. Adding a messenger to the Antivirus Whitelist often solves the problem instantly.

  • πŸ›‘οΈ Open the Security app.
  • πŸ›‘οΈ Go to the Licenses or Settings section.
  • πŸ›‘οΈ Find the white list or exceptions.
  • πŸ›‘οΈ Add all the necessary messengers and email clients.

Each application has its own nuances of work on the shell MIUI. For example, Telegram requires a separate setup to work. PUSH-Notifications, and WhatsApp is critically dependent on Google Play services. If you don't take these details into account, the general settings may not work.

Viber and WhatsApp often require enabled geolocation in the background for some file transfer functions to work correctly, which can also be blocked by the power saving system. In Telegram, it is important to check the notification settings inside the application itself, as they can overlap the system ones.

⚠️ Warning: Deleting and re-installing the app will reset all of its internal notification settings.Before deleting, make sure you have a backup of the chats.

In some cases, cleaning up the cache of Google Play helps. Since many notifications go through Google’s servers (FCM), a failure in this service will cause all applications to remain silent. Go to Settings β†’ Apps β†’ All Apps β†’ Google Play Services and click Clear Cache.

πŸ’‘

The specific settings inside the messenger itself take precedence over the system settings, so check them first if the general methods didn’t help.

Why do notifications come with a delay?
The most common reason for delay is that the system wakes the application when the screen is turned on, which is the behavior of the energy saving mode, and you need to set the battery mode "No restrictions" to eliminate delays.
Can resetting settings help?
Resetting all settings to factory (Settings β†’ Advanced Settings β†’ Reset) is guaranteed to solve the problem if it is caused by a software failure. However, it will delete all your data, so the method is worth using last.
Does the subject matter affect notifications?
Third-party themes from MIUI Themes may contain errors in the notification display code. If the problem occurs after a change in the theme, return the standard theme and check the system.
