Modern Xiaomi smartphones, which run on the shells of MIUI or the new HyperOS, are equipped with aggressive power management algorithms, which are designed to extend battery life, but often act too radically, closing the background processes of messengers, navigators and other important applications. Users often face a situation where notifications come with a delay or do not come at all, and applications “fly out” immediately after they fold.
The solution is to fine-tune battery settings for each application or to change the system’s operating mode globally. Disabling battery saving allows programs to run in the background without restrictions, consuming more power, but ensuring the stability of notifications and data synchronization. It’s important to understand that ignoring power saving completely can reduce the device’s operating time from a single charge, so settings require a customized approach.
In this article, we’ll take a look at all the power management options available on Redmi, Poco and Black Shark smartphones. You’ll learn how to set up exceptions for important programs, change the global settings of the system, and use the hidden power of the engineering menu to fine-tune.
Global settings of the energy saving regime
The first step to optimizing the smartphone is to change the overall power mode. In the standard state, the system often offers a "Balanced" or "Economic" mode that limits background activity. Switching to "Performance" mode removes most software constraints, allowing the processor to operate at maximum frequencies and without interrupting the background processes of applications without urgent need.
To change the mode, you need to go to the Settings → Battery menu. Here you will see the mode switch. Choosing the Performance option will immediately change the behavior of the system: animations will become smoother, but energy consumption will increase. This option is ideal for gaming sessions or working with heavy applications, but is not recommended for continuous use if you are away from the charger.
⚠️ Attention: Performance mode can significantly increase the temperature of the device body during heavy use. Watch the heating to avoid trottling (reduced processor frequencies due to overheating).
The alternative to completely switching off savings is to use No Limits mode for specific scenarios. However, if your goal is to maximize system responsiveness right now, global switching will be the most effective solution. Remember that after a device reboot, some settings may reset to default values, so check their status periodically.
💡
Global Performance mode removes the limitations of the processor, but increases battery consumption by 15-25% in standby mode.
Individual configuration of applications through the battery menu
The most flexible management tool is to set up each application separately, and MIUI-based Android allows you to prioritize energy saving for each program installed, allowing you to keep instant messengers active while limiting background activity of less important utilities such as games or rarely used services.
To set exceptions, go to Settings → Applications → All apps. Select the program you want from the list (such as Telegram or WhatsApp). In the menu that opens, look for “Saving Charge” or “Activity Control.” Here you will be offered three options: “Saving Charge (recommended)”, “No restrictions” and “Limit background activity”.
Selecting the "No Limits" option completely disables the "Sleeping" of the application by the system, which guarantees instant messaging and background content loading. For navigation applications, health trackers or smartwatches, this parameter is critical, since breaking the connection with the server will lead to loss of data or route.
☑️ Checking the application settings
It’s worth noting that after major updates to the HyperOS or MIUI operating system, these settings can be reset. Periodic checking of important applications helps avoid sudden notification problems. If you install a new application, immediately set the correct operating parameters so that the system does not apply an aggressive default saving algorithm to it.
Autostart and background process management
In addition to battery settings, Xiaomi’s shell has a separate app launch control mechanism known as Autostart. Even if you’ve allowed the program to run without battery menu restrictions, it may not start after restarting or clearing memory if it’s not allowed to autostart.
To control this setting, open the Security app (green zipper icon) built into the system. Go to Permissions and select AutoRun. This lists all installed applications. Turning on the switchboard in front of the desired program allows it to start with the operating system and restore its operation after cleaning the RAM.
- 🚀 Messengers: Be sure to turn on autostart for WhatsApp, Telegram, Viber, so as not to miss calls.
- ⌚ Wearables: Watch apps (Mi Fitness, Zepp Life) must have autorun access for constant synchronization.
- 🎵 Music players: Turn on for background music playback without stopping when locking the screen.
- 📧 Email clients: Needed to receive emails instantly without manual update.
There is also a hidden section called Other Permissions, where you can find the settings "Master on top of other applications" and "Run in the background." Make sure these items are also activated for mission-critical services. A comprehensive approach to configuring all three settings (battery, upstart, background) gives you a 100% guarantee of stable operation.
Why are the settings resetting?
Using Developer Mode to Disable Optimization
For advanced users who have experienced particularly stubborn application closures, hidden settings can be accessed through the developer menu, a method that disables MIUI Optimization system optimization, which is often the main cause of background process problems, especially in global firmware versions.
To activate the developer menu, go to Settings → On the phone and press quickly 7-10 once under the heading “Version” MIUI" or "Version". OS". After the notification that you have become a developer, go back to the main settings menu, open More → For developers, scroll down to the bottom of the "Inclusion" section. MIUI Optimize and turn off this switch.
Once the optimization is turned off, the system will ask for a reboot. Once turned on, you will notice that the interface has changed and some system fonts may change. This is normal behavior, as the corporate interface optimization layer is turned off. However, this step often solves problems with Google Pay, banking applications and complex background services that previously could not work consistently.20
| Parameter | Standard status | After optimizing | Impact on the system |
|---|---|---|---|
| Background processes | Hardly limited. | They work according to Android standards. | Increased RAM consumption |
| Interface. | Optimized by MIUI | Standard Android | Changes in fonts and indentations |
| Notifications | Aggressive filtration | Full delivery | Increase in the number of notifications |
| Battery | Economy regime | No restrictions. | Reduced working hours |
⚠️ Attention: Disconnection MIUI Optimization can lead to incorrect display of some interface elements and increase the consumption of RAM. Use this method if other methods have not helped.
Specifics of work in HyperOS mode
With the release of the new HyperOS shell, which replaced MIUI, the memory and energy management algorithms have changed, the new system uses a more intelligent allocation of resources, but the principle of “austerity” remained basic for many regions. In HyperOS, energy saving settings were unified and moved to deeper menu levels.
The new shell has an expanded "Advanced Settings" section inside the battery menu, and here you can find the "Background Save" feature, which is also recommended to be disabled for important applications. In addition, HyperOS is more actively using artificial intelligence to predict user actions, so the "learning" period of the system after resetting can take up to 3-5 days.
HyperOS users should also look at the Battery widget on their desktop, which offers quick profile switching unlike previous versions. If you notice that the phone has started to strangle apps after the update, check if Super-Savings mode has automatically activated, which limits even basic functions.
💡
After upgrading to HyperOS, give the phone 2-3 days to adapt the AI algorithms. During this period, you should not dramatically change the energy saving settings, so as not to disrupt the learning process of the system.
Solving problems with specific applications
Some applications require a special approach because of their server architecture. For example, messengers use different push notification protocols, and standard Android settings can block their unique ports. For these cases, there is a method of "freezing" settings through ADB, but for most users, the correct manual configuration is enough.
Not only is it critical for Telegram and WhatsApp that you allow the background to work, but you also have permission to work in Do Not Disturb mode. Sometimes the system blocks the notification sound even if the app itself is working. Check the notification settings inside the app itself and make sure that you select sounds other than "No Sound."
If you use a Mi Band or Amazfit smartwatch, the problem of communication breaks is solved comprehensively. In addition to all the above settings, you need to find a paired device in the Bluetooth menu and click on the gear settings, enabling the option to show notifications and removing background restrictions for the Bluetooth system service.
- 📱 Instagram: Often closed when you download stories Solution: No restrictions" + Autostart.
- 🎮 For stable ping, turn on Game Turbo and add the game to exceptions.
- 🗺️ Navigators: Be sure to turn on "Work in the background" and "Display over other windows".
In rare cases, a complete reinstallation of a problematic application after resetting all the power saving settings for it helps, allowing the application to re-request all the necessary permissions from the system, and sometimes this "shaking" helps to establish a proper dialogue between the application and the OS.
