Xiaomi’s current smartphones, which run MIUI and HyperOS shells, are known for aggressively optimizing power consumption. The system seeks to maximize battery life, often at the expense of user experience, by forcibly closing apps in the background. This causes important messages from messengers to arrive with a delay, and navigators to stop plotting their route when the screen is off. Understanding how to turn off energy saving on the shaomi becomes a key skill for comfortable use of the device.
In this article, we will take a look at all the battery protection levels available in the system and learn how to manage them correctly. You will learn where hidden settings hide, how to set exceptions for specific programs and whether you should completely abandon energy savings.
Why the system blocks the work of applications
The firmware’s energy-saving algorithms are designed for the typical user who rarely changes the default settings. The system analyzes usage patterns and decides which processes can be “freezed” or completely completed to maintain charge. However, this mechanism often works too radically, perceiving the background activity of even the programs you need as malicious or redundant.
The main problem is that the standard Android settings and MIUI add-ons duplicate each other, creating a multi-step system of restrictions. When you just fold an application, it does not remain in the RAM indefinitely. After a certain period of inactivity, the task manager forcibly clears the memory, resetting the state of the program, which is why users often complain that the music stops and files do not load if the screen goes out.
There are also different battery scenarios that can be activated randomly, such as Ultra mode or standard saving mode, which not only changes the brightness of the screen, but also limits the processor frequency, prohibits background data synchronization and vibration, and disabling these functions returns the device to full performance, but requires manual intervention in the system menus.
Global power saving shutdown
The easiest way to get the system back to full freedom is to change the battery mode in global settings. By default, the phone can be in Balance or Saving mode, which immediately imposes a number of restrictions on the background processes. Switching to Performance mode removes most software locks, allowing applications to work without power consumption restrictions.
To go to the menus you need to open the settings and find the partition associated with the battery. In new versions of the shell, the path may be slightly different, but the logic remains the same. After selecting the performance mode, you will notice that the device has reacted faster, but the charge consumption may increase. This is a normal reaction, since the processor stops artificially lowering its frequencies.
⚠️ Warning: Performance mode can significantly reduce battery life during the day. Use it if you are critical to instant notification delivery and heavy-duty applications.
Also worth noting is the memory optimization feature, which is often turned on by default, which aims to keep as much RAM as possible free by constantly unloading running applications from it, and disabling this option allows programs to stay in a folded state longer, which is especially useful for multitasking.
Configure restrictions for individual applications
Global settings are only half the solution: To ensure that a particular messenger, navigator or activity tracker works, you need to customize exceptions for each application, and Xiaomi allows you to set your own energy saving scenario for each installed program, ignoring the general rules.
You'll need to go to the application management menu and find the battery section, and here you'll see a list of all the programs installed, and you can choose one of three modes for each of them, which will determine how aggressively the system will kill the process after it's folded.
- 🔋 Energy savings: Standard mode limiting background activity to extend battery life.
- 🚀 Without limitations: the application can run in the background for as long as you want, using all available system resources.
- 🛑 Limit Activity: A hard mode that closes the app almost immediately after you stop using it.
By choosing the "No Limits" option, you give the program a full carte blanche. This is ideal for Telegram, WhatsApp, email clients and navigation systems. However, for simple utilities that you rarely use, it is better to leave the standard settings so that they do not waste charge.
Working with Auto Start and Permits
Another important aspect that affects how programs work in the background is autorun control. Unlike pure Android, the MIUI shell requires explicit permission to run applications with the system. If the program is not authorized to autorun, it will not be able to work correctly in the background after the phone restarts.
To manage this, there is a special menu, often hidden in the Applications section or available through the search for settings on the request for "autostart", here is a list of all programs that can start automatically. Turning on the toggle in front of the desired application is a mandatory step for the correct operation of notifications.
And you also need to check the permissions to display over other windows and access data in the background. Without those rights, even with power savings turned off, the system can block pop-ups or interrupt data transmission when the screen is off. This is part of the security system, but it often interferes with normal operation.
☑️ Checklist of application settings
Comparison of battery operating modes
To better understand the trade-offs you make when choosing a mode, it’s helpful to familiarize yourself with the technical differences: Each level of battery protection affects CPU frequency, display brightness, and network activity differently.
| Parameter | Productivity | Balance (Standard) | Savings |
|---|---|---|---|
| CPU frequency | Maximum | Adaptive | Reduced. |
| Background synchronization | Permitted. | Limited. | Forbidden. |
| Vibration and sounds | Complete. | Complete. | Disabled. |
| Screen brightness | No restrictions. | Auto/Manual | Reduced. |
As you can see from the table, Balance is the middle ground, but for users who care about the stability of specific services, it can be too restrictive, and Performance actually disables most saving algorithms by relying on the settings of individual applications.
It's worth noting that switching between these modes can be automated with scripts, for example, you can set the phone so that when you start the navigator, you automatically turn on high performance mode, and at night you activate hard savings.
Additional settings MIUI and HyperOS
Recent firmware versions have added additional features that can interfere with applications even after the major limiters are turned off, such as Advanced Memory, which uses a portion of the storage as virtual RAM. While this sounds useful, in some cases it leads to more aggressive crowding out of older applications from real RAM.
Also worth paying attention to screen settings: Read Mode or adaptive brightness can conflict with user desires if they are set too aggressively. The Screen section recommends turning off all automatic enhancements if you want predictable device behavior.
