Modern Xiaomi smartphones running MIUI shells or the new HyperOS have powerful power-saving algorithms that can by default aggressively “unload” background apps, which often leads to the fact that the user does not see important messages from messengers, emails or alerts from social networks until he opens the application manually. Understanding how to properly configure this system is critical for comfortable use of the device.
In this article, we’ll look at not only the basic switches, but also the hidden settings that are often overlooked, and you’ll learn to create exceptions for critical contacts and apps so that your phone never stays silent at the right time, while keeping battery power in other use cases.
Basic setting of the notification panel
The first step is always to check the global settings of the system. The notification panel is the central hub where all incoming data is decided. → Notifications and status bar. Here you'll see the "Show Notifications" switch that should be active.
However, there is an important nuance in Xiaomi’s ecosystem regarding display style: Unlike pure Android, you can choose between a classic list and a more modern, but less informative style. To maximize control over incoming events, you should use an advanced display style that allows you to see more text of a message without opening the application.
Also in this section is the setting "Indicator in status bar" If you have missing icons of envelopes or messages on the left at the top of the screen, most likely, this option has gone wrong. Make sure that the desired categories are selected for the display of "Digits" or "Dot", otherwise you may miss an important event just by looking at the locked screen.
- 📱 Style: Select “Extended” for detailed viewing.
- 🔔 Sound: Check if the No Sound profile is worth it globally.
- 👁️ Privacy: Hide content on a locked screen if necessary.
Don't ignore the Notification Management section inside the same menu, where you can quickly turn off annoying alerts from games or stores without removing the apps themselves, which helps clear up the noise and focus on what's really important.
Set up notifications for specific applications
The most common problem users have is the lack of sound from WhatsApp, Telegram or Viber. The fact is that in Android 12 and later, which run MIUI 14 and HyperOS, each application has its own hierarchy of notification channels. Just turn on “Allow notifications” is often not enough.
To set things up in detail, go to Settings → Apps → All apps, find the messenger you want, and select Notifications. You will see a list of categories: Messages, Calls, Groups. By clicking on the category text (not the switch), you will be taken to a deep settings menu.
⚠️ Warning: If the Important (or Priority) switch is turned off, the system may not consider your messages to be urgent and wake the screen or make a sound even if the volume is on.
It also adjusts the behavior on the locked screen, so you can allow content to be displayed, only show an icon, or completely hide information. For instant messengers, it is often more convenient to choose the option of “Show notifications and their contents” so as not to unlock the phone to read short lines.
💡
Use the “floating window” feature for instant messengers in the notification settings to respond to messages without interrupting your video or other apps.
It is also important to check the permission for "Pop-up notifications" (or "Banners"). If this option is disabled, the message will come silently and you will only see it by unlocking the device and lowering the "curtain."
Battery optimization and background work
The main reason notifications don't arrive on time is because MIUI optimizer works, and it tends to save power by freezing processes you're not using right now, and if the application is frozen, it can't connect to the server and receive a new message.
To exclude an application from aggressive optimization, open it in the installed list (via Settings → Applications), select Activity Control (or Energy Saving) and set the value “No Limits” to allow the application to run in the background without energy consumption restrictions.
If the app is not authorized to auto-start, after restarting the phone or cleaning the memory, it may not start on its own and notifications will stop coming before your first manual opening.
☑️ Setting up energy saving
Sometimes it helps to lock the application in memory. Open the running applications (swipe from the bottom up and hold or menu button), find the right window and press the lock, which will prevent it from unloading when you clear the memory with the Crack button.
| Energy saving regime | Impact on notifications | Recommendation |
|---|---|---|
| Balance | Standard delay | Suitable for most people. |
| Economical | Severe delay or blockage | Only at low charge. |
| Ultra | Only calls and SMS work. | In an emergency situation |
| No restrictions. | No delays, high expense. | For gaming smartphones |
Remember that removing restrictions from dozens of apps can significantly reduce battery life. Apply the No Limits method only to programs where instant messaging is important.
Do Not Disturb and Schedules
Do Not Disturb (DND) is often turned on randomly or on a schedule that the user forgets about. In this mode, the phone can vibrate when calls are made, but the screen does not light up, and notifications do not emit sounds.
In Sound and Vibration → Do Not Disturb, you can set exceptions, such as allowing interruptions only from selected contacts or repeat calls (if someone calls a second time within 3 minutes, this is considered urgent).
Also, check the “Planned Inclusions” section. Xiaomi may have a schedule that includes quiet mode at night by default. If you are waiting for an important call at night, make sure that the exceptions add the right contact or turn on the “Repeat Calls” mode.
⚠️ Note: Do Not Disturb mode can block the alarm clock in some firmware versions unless the appropriate exceptions in the Priority Interrupt menu are configured».
Special attention should be paid to Game Turbo. If notifications disappear during the game, go to the Security app → Game Turbo → settings (cogs) → Notifications. There you can allow Floating Notifications to see messages on top of the game.
Working with contacts and select persons
In the Xiaomi ecosystem, there is a concept of “Favorite Contacts” that works at the system level, rather than at the individual application level, which allows you to skip the “Do Not Disturb” mode even for those who are not on your lists inside WhatsApp or Viber.
To add a contact to the exclusion list, go to the Contacts or Phone app, open the card you want and click on the asterisk or select Add Exceptions. Now calls and SMS from that person will go away forever.
For messengers that aren't integrated into the system phone book that deeply, it's important to set priority within the app itself. In Telegram, it's Favorites or chat fixing; in WhatsApp, it's dialog fixing. While it doesn't guarantee bypassing system locks, it does prioritize the process in the eyes of the user.
There's also Pocket Mode, which prevents accidental taps in your pocket. Sometimes it can lock the screen when you make an incoming call if the proximity sensor is contaminated. Wipe the top of the screen if the person complains that the beeps are coming but you can't answer.
Advanced settings for HyperOS and MIUI 14
Newer versions of the shells have added layers of memory protection, and if standard methods don’t work, it’s worth checking the Developer Options settings (for advanced users), but more often than not, the problem lies in the new features of Advanced Optimizer.
HyperOS has changed the logic of the background, now the system more aggressively closes “heavy” applications, recommends manually open all important messengers after restarting the phone at least once, so that the system “remembers” their activity.
Secret team to reset notification settings
You should also pay attention to the updates to the apps themselves. Older versions of Viber or Skype may not work properly with the new Android notification APIs. Go to Google Play or GetApps and update all programs to the latest version.
💡
The main cause of the problem is aggressive energy saving, and the "No Limits" mode for instant messengers solves 90% of delivery problems.
