How to turn off Xiaomi’s ultra-power saving: the complete guide

Xiaomi’s modern smartphones are known for their high autonomy, but aggressive optimization of MIUI and HyperOS systems often leads to undesirable consequences. Users may face a situation where important messages do not arrive on time, and applications are closed immediately after they are folded, this is a direct consequence of the energy saving system, which ruthlessly “strangles” background processes in order to save every percentage of charge.

Device owners often wonder how to turn off Xiaomi’s ultra-power saving to return the phone to normal functionality. Standard settings can be hidden or scattered across menus, causing confusion. In this article, we’ll take a look at all the power management techniques available, from simple switches to deep developer settings.

You have to understand that completely disabling all the restrictions can lead to faster battery discharge. However, for most users, stable operation of messengers and navigators is more important than an extra couple of hours in standby mode.

What is ultra-energy saving and how does it work?

Ultra Battery Saver is an extreme algorithm for managing the resources of the processor and network modules. Unlike conventional power saving, this mode does not just reduce the brightness of the screen or turn off vibration, it actually freezes the entire operating system, leaving only the basic functions of calls, SMS and hours active, and this mode often starts automatically when a critical charge level is reached, for example, 10% or 5%.

When the phone goes into this state, the interface changes beyond recognition: the desktop is replaced by a black screen with large icons of the most necessary applications. Background data synchronization completely stops, the Internet can be turned off periodically to save energy, and notifications from social networks stop coming until the moment of manual unlocking and opening the application, this creates the illusion of a broken phone.

The MIUI Optimization system process, or the new HyperOS Service, constantly monitors running applications, and if the program is not on the exclusion list, it will be forcibly stopped shortly after the user has folded it, a behavior embedded in the shell core that requires manual intervention to adjust to the needs of the particular user.

⚠️ Warning: Staying in ultra-energy saving mode for a long time may cause you to miss an emergency call or an important notification from security services.

Understanding the mechanics of these constraints allows you to manage them effectively, and instead of constantly charging your phone, you should set up your system correctly once to make it work predictably, which is especially true for those who use the smartphone as their primary tool for work and communication.

The main ways to disable the mode through settings

The most obvious, but not always noticeable, way to get out of austerity is at the control center, and many users accidentally activate this feature by trying to turn on the usual "Energy Saving" mode, which is less stringent. To turn off, you need to lower the notification curtain and find the battery icon, if it's illuminated or it's labeled "Ultra", then the mode is active.

The deeper setup is done through the main menu of the device's settings. You'll need to follow the Settings → Battery path. This is where the main power controls are located. The top of the screen usually displays the current status and the slider switching between modes. If the Ultra slider is active, it needs to be put into an inactive state.

It is important to distinguish between energy savings and ultra energy saving: the first restricts background activity and reduces the frequency of the processor, the second turns the smartphone into a “caller.” For comfortable use in most cases, it is enough to include ordinary savings or completely abandon it by adjusting individual settings for applications.

If the standard path doesn't produce the desired result, you may have a specific version of the firmware installed on your device, and then you should search by settings, type the word "battery" or "energy saving" into the menu search bar, and the system will suggest the transition to the desired partition, which is a universal method for all versions of MIUI and HyperOS.

Set up exceptions for important applications

Even after the global ultra-saving mode is disabled, the system can continue to aggressively close individual applications, and to avoid this, you need to configure exceptions, which will allow critical programs such as Telegram, WhatsApp or navigators to work in the background without restrictions, this procedure requires care, since the menu can be called differently depending on the version of the software.

You need to go to the application management menu. This is usually done through Settings → Applications → All Apps. Find the program you want in the list and click on it. Inside the app menu, look for "Battery Saving" or "Battery." Here you need to select "No Limits" or "Background Start."

• 📱 Open the settings of a particular application and select AutoStart to allow it to turn on with the system.
• 🔒 Lock the application in memory: open the list of running applications, press the desired and press the lock icon so that the system does not unload it.
• 🔔 Check the permissions to access notifications, making sure they are not blocked at the system or antivirus level.

There's also a hidden Battery Saver menu that you can access through an engineering menu or a special command, but for the average user, standard settings are enough. The main thing is to stay on top of the 5-10 most important programs for you. This will take no more than 10 minutes, but save your nerves in the future.

⚠️ Attention: Granting full background rights to navigation applications (Yandex.Navigator, Google Maps) significantly increases energy consumption when the screen is turned on.

After making changes, it is recommended to restart the device, which is necessary to ensure that the new rules take effect and that Power Manager system services correctly update their exception lists.

Manage through the Developer Menu and ADB

For advanced users who want to gain full control of the system, there are more powerful tools. The developer menu allows you to disable some system optimizations that are not visible in the normal interface. To activate this partition, you need to quickly click on the build number in the About Phone section several times.

The developer menu should look at items related to background processes, such as the "Background Process Limit" option should be set to "No Limits" or the default default value, and it is also worth checking the Standby Optimization settings if such an option is present in your firmware version.

Be careful, though, because interfering with system processes through ADB can cause the device to run in an unstable way, for example, turning off all restrictions can cause the processor to overheat at night when the phone is idle, and use these methods only if you understand what each option is responsible for.

In some cases, resetting battery optimization settings helps, and you can do this by finding the "Reset Optimization Settings" or similar item in the developer menu, which will return all system algorithms to factory values, which sometimes solves problems with the "glue" behavior of the battery after updating the firmware.

Comparison of battery operating modes

To make a final decision on the settings, it’s helpful to understand the difference between the modes available. Manufacturers offer multiple levels of charge protection, each with different features and use cases. The right mode depends on how you use your smartphone during the day.

Below is a table that will help you navigate the differences and choose the best strategy for your device.

As you can see from the table, Ultra energy saving is a survival mode, not a routine one. If you don't have to stretch 5% of your charge for a few hours, you'd better keep it off. A normal mode with well-tuned exceptions will give you a better balance.

And it's also worth mentioning the adaptive battery, which uses artificial intelligence to learn your habits, and it decides which apps to restrict, and if you trust Google or Xiaomi algorithms, you can leave it on, but it doesn't always work perfectly.

Solving Frequent Problems and Errors

Sometimes users are faced with a situation where the power saving mode does not turn off or turns on on itself, this can be caused by a software failure or damage to system files. First of all, you should check whether there is an automatic schedule for saving, which is a feature on the battery menu and can be activated at a given time or at a certain level of charge.

Another reason could be a malfunction of the battery itself, and if the battery controller is transmitting incorrect charge data, the system can turn on protection immediately, in which case only calibration of the battery or its replacement in an authorized service will help, and the software methods will be powerless here.

• 🔄 Perform a full Hard Reset if the problem has occurred after a failed system update.
• 📲 Check for firmware updates, as newer versions often contain power management bug fixes.
• 🧹 Remove recently installed SEO apps that may conflict with system settings MIUI.

If the phone keeps behaving strangely, try Safe Mode, and when you boot up, you can see if the third-party app is to blame. To enter Safe Mode, you usually need to press the off button on the screen, and then hold your finger on the Turn Off button for a long time until the appropriate sentence appears.

💡

Use the original charger to calibrate the battery: completely discharge the phone before turning off, then charge up to 100% when off.

In rare cases, cleaning the cache of the system application "Security" or "Services and Feedback" helps. Accumulated errors in the logs of these services can cause cyclical inclusion of saving modes. Clearing the cache will not delete your personal data, but can correct software glitches.

Impact of HyperOS Updates on Power Management

With the release of the new HyperOS shell, Xiaomi has redesigned its power management algorithms. The interface has become more concise, but some features have been moved or renamed. Users who upgrade with MIUI 14 may feel confused at first without finding the usual switches.

The new system focuses on intelligent resource allocation, and now it decides when to put the application to sleep based on how often it is used, which means that manually turning off the energy saving might not have the same effect as the older versions unless the usage profiles are set up.

💡

In HyperOS, it is critical to set up a Job or Game profile in the Security app so that the system does not interfere with background processes during active tasks.

HyperOS has also changed the way battery widgets work, so that they can offer smart scenarios that are better taken into account, but if your goal is maximum performance and no notification delays, manual exception settings remain the only reliable method.

Remember that every major upgrade takes time to train your system. In the first days after installing HyperOS, battery consumption can be increased and background processes unstable. Give your phone a week to adapt to your usage style before deciding if you need to make a deep adjustment.
