How to turn off battery savings on Xiaomi: the complete guide

Modern Xiaomi smartphones are famous for their autonomy, but aggressive optimization of MIUI or HyperOS systems often works against the user. Device owners often face a situation where messengers do not send notifications on time, the navigator turns off at the most inopportune moment, and background processes are simply killed by the system for the sake of saving charge. This is not a bug, but a feature of built-in algorithms designed to extend the battery life.

If you want your phone to behave predictably and not limit the performance of important applications, you need to understand the power saving settings. In this article, we will detail how to turn off battery savings on Xiaomi so that your applications work correctly without losing the overall efficiency of the device. Understanding these settings is critical for comfortable use of a smartphone.

It's worth noting that completely disabling all the restrictions can lead to faster battery discharge. However, for modern models with fast charging and capacious batteries, this is often an acceptable compromise for the sake of software stability. Let's look at all the available methods of energy management.

Managing energy saving mode in settings

The most obvious and basic way to manage energy consumption is in system settings. This is where the global behavior of the smartphone is set. When you turn on the savings mode, the system automatically restricts background activity, reduces the brightness of the screen and turns off data synchronization. For many users, this is convenient, but for those who need maximum responsiveness, these functions are better deactivated.

To access these parameters, you need to go to the battery settings section, and here you will see the current charge level and active power profile. Power saving mode often turns on automatically when it reaches 20% or 10%, but it can be adjusted manually. Disabling this mode will return the phone to full performance of the processor and graphics accelerator.

It's important to understand the difference between normal mode and ultimate saving mode, which turns your smartphone into a simple "caller," turning off almost all smart functions, and if you accidentally activate it, you can only return everything back through the settings menu or an emergency call.

⚠️ Warning: Forced shutdown of system restrictions on low battery charge can cause the device to suddenly shut down if battery capacity is critically small.

Configure restrictions for individual applications

The most common problem Xiaomi users have is the lack of notifications from WhatsApp, Telegram or email clients, which the system considers to be “heavy” and restricts their performance in the background. To fix this, you need to customize each application individually, which is a more flexible approach than the global saving switch.

First, you need to find a list of all the programs installed. In the settings menu, select "Applications" and then "All apps." Find the desired program, such as messenger, in the list. Inside the app menu, you are interested in the "Saving Charge" section. Here, the default value is often "Saving Charge", which blocks work in the background.

Change the setting to No Limits, which gives the app full permission to run in the background, use internet and CPU time without system interference, and it’s also helpful to check if Auto Start is enabled if it’s available in the same menu or in a special Security app.

When the settings change, it is recommended to close the application completely and restart it, which ensures that the new rules will take effect immediately, and if the notifications do not come, check the permissions to access the network and the background data transfer.

Use of the Security App

In the MIUI and HyperOS shell, the central element of management is the built-in Security app, which combines antivirus, memory cleaner and, importantly for us, battery manager, which many users ignore by relying on the standard Android menu, but this is where the deepest optimization settings are hidden.

Run the Security app and find the Battery icon. In the upper right corner, you'll see the gear icon, which is the entrance to advanced settings. You can turn off Memory Optimization, which often closes applications immediately after you turn them down. You can also find Sleep Mode, which is worth turning off for important programs.

This section also often contains Activity Control, which shows which applications are most energy-consuming, and if you see system processes or programs you don't need, you can limit their performance, but you'd better set an exception for messengers and work tools.

Disabling MIUI Optimization for Developers

There is a more advanced method that disables system optimization of MIUI, which can radically change the behavior of the system, making memory and battery management less aggressive, but be careful: this mode is designed for developers and can affect the stability of some functions.

To activate this mode, you first need to unlock the Developer Menu. Go to About Phone and quickly click 7-10 times on either MIUI Version or OS Version until the message “You’ve become a developer” appears.

Go to Settings → Advanced Settings → Developer. Scroll down to the bottom. There you will find the "Enable MIUI Optimization" switch, which will prevent the system from forcing processes to end. After the switch, the phone will ask for a reboot.

⚠️ Attention: Disabling optimization MIUI This method can lead to increased battery consumption and changes the interface of some system dialogs.

After you reboot, you might notice that app permissions are requested more often, and the interface has changed a little bit. That's normal behavior. If you notice critical interface errors, you can turn the option back on.

Specifics of background work

One of the main reasons users are looking for a way to turn off savings is the background processes are not working properly. Android and its shells, such as HyperOS, tend to keep charge by "freezing" apps that you don't use right now.

To keep the application running, it's not enough to just remove the battery constraints, you also need to fix it in memory. Open the menu of running applications (swipe from the bottom up and hold or menu button), find the window of the desired application and press the lock, which will prevent the system from unloading it from RAM during cleaning.

It's also worth checking your data settings. In some cases, the restriction is not about CPU time, but about accessing the Internet in the background. SIM-maps and mobile traffic, find the right application and make sure that the Background Connection slider is active.

💡

Tip: For navigation applications (Yandex.Maps, Google Maps), be sure to turn on “High accuracy” in geolocation settings, otherwise GPS can be turned off when the screen is turned off to save energy.

Additional screen and network settings

While the main question is about software constraints, you can also keep in mind the physical parameters that the system considers part of the economy: adaptive brightness and smart network can conflict with the user's desire to have a constant response. If you've turned off all the restrictions on applications, but the phone still behaves strangely, check these points.

In the Screen section, turn off Adaptive Brightness if it doesn't work properly and set a static value. In the Connection and Sharing section, check your Wi-Fi settings. The "Use Wi-Fi in Sleeping Mode" feature should be set to "Always," otherwise the phone will lose communication with the router when the screen goes out.

Some Xiaomi models have a memory extension feature that uses part of the storage as RAM. In rare cases, this can affect speed and power consumption. If you have enough physical RAM (8 GB or more), you can try turning this feature off in the Advanced Settings section to check for stability.
