Users of Xiaomi, Redmi and Poco smartphones often experience a situation where the device automatically or accidentally goes into extreme power saving mode, in which the interface changes beyond recognition: only basic calls and messages remain, and access to other applications is blocked, which can cause panic, especially if the phone is used by an elderly person or a child who does not understand where the icons are gone.
The main problem is that the standard output through the βSwitch offβ button sometimes does not respond to touch, or the system hangs in the interface reboot cycle. The ultra-saving mode is designed to extend the battery in critical situations, but its aggressive optimization of processes often leads to software failures. Understanding the mechanism of this function is the first step to successfully solving the problem without losing data.
In this article, we will look at all known methods of forced exit from this state. We will look at regular ways to disconnect through the menu, methods to restart the system, as well as more complex options using engineering menus and ADB. It is important to act consistently so as not to aggravate the situation and not lose important contacts.
Standard methods of disconnecting energy saving
The most obvious and safe way to do this is to use the built-in MIUI or HyperOS system. Usually, a large "Stop" or "Stop" button is displayed on the lock screen or desktop, and pressing it should return the phone to normal operation, but if the interface is delayed, patience is required.
If the button is not visible, you should find the battery icon in the upper right corner (or in the notification curtain if available). When you press it, you open a menu where you can check the box from the option "Ultra Saving Mode" or "Ultra Battery Saver." In some versions of the firmware, the path looks like Settings β Battery β Mode Switch.

If the screen reacts to late touches, press the switch off button slowly and hold your finger for 1-2 seconds so that the system has time to register the event.
Sometimes the system requires confirmation of action. A dialog box may appear on the screen warning that some applications will stop working in the background. You must agree to the conditions for the unlock process to be completed. If the screen flashes after that, but the mode does not turn off, try repeating the procedure again, before closing all background tasks.
β οΈ Attention: If the screen goes off and lights up again with the same interface after pressing the switch button, then the systemui process is stalled. In this case, the software switch will not help, and you will need to restart the device.
Forced resetting of the device
When software methods fail, the most effective way is hard reset, which is safe for your personal data, because it doesn't delete files, it just forcibly restarts the operating system. On Xiaomi smartphones, this is done by a combination of physical buttons.
To perform a reboot, you need to press the power button and hold it for 10-15 seconds. Some models require simultaneous pressing of the power button and the volume button. The device must vibrate, after which the Mi or Redmi logo appears on the screen. Once the phone is fully loaded, the ultra-saving mode usually turns off automatically.
βοΈ Hard reset algorithm
There is a nuance associated with models without a physical 3.5mm connector, where the bottom button can be combined with other functions. If the standard combination does not work, try to pinch the power button and one of the volume buttons (any) at the same time.

Battery settings and eliminating auto-activation
After successfully exiting ultra-saving mode, it is critical to set the system so that it does not turn on again automatically. Often users activate the "Switch on automatically at less than X% charge" function, forgetting this, and checking these settings will help to avoid a repetition of the situation.
Go to Settings β Battery. This is the ultra-savings mode switch. When you click on the gear next to it or enter the advanced settings, you will see auto-start options. Make sure the auto-enabled slider is off. It's also worth checking the memory optimization settings, which can aggressively close the background processes, mimicking energy saving behavior.
The table below gives you comparative characteristics of battery modes so you understand the difference and donβt confuse them:
| Parameter | Regular regime | Savings regime | Ultra saving |
|---|---|---|---|
| Screen brightness | Complete. | Reduced. | Minimum |
| Background processes | Everyone active. | Limited. | Just calls./SMS |
| Frequency of update | Maximum | Standard. | 60 Hz or lower |
| Vibration. | On. | On. | Disconnected. |

Automatic ultra-savings are often activated when the charge drops below 10% or 5%, which is worth considering when planning long trips.
Using Safe Mode for Diagnostics
If the phone leaves ultra-saving mode but returns to it immediately, it may be caused by a third-party app, in which case Safe Mode will help, which only loads system components, allowing you to identify the culprit of the failure.
To enter Safe Mode on Xiaomi, you usually need to press the off button on your desktop and then hold your finger on the βoffβ icon on the screen for a long time. The system will suggest going to Safe Mode. If the problem has disappeared in this mode, then the conflicting application is found. Delete recently installed programs, especially memory cleaners or third-party batteries.
- π± Launcher conflict: Third-party shells may incorrectly interact with the system mode of energy saving.
- π Calibration error: Battery control app may not read sensor data correctly.
- π‘οΈ Antiviruses: Aggressive antiviruses can block the exit from the mode of saving, considering it a threat.
Once you remove the suspicious software, restart your phone as normal, and if the problem is solved, you've found the cause, and if you're in safe mode, the phone gets stuck in saving, the problem goes deeper, either in system files or hardware.
Resetting and extreme measures
When software errors become critical and nothing helps, you can reset your settings. Wipe Data will delete all your photos, contacts and applications, so this method is only used as a last resort.
Resets can be done via the Recovery Mode menu, turn off the phone completely, then press the power button and the volume button. In the menu that appears (manage volume buttons, select the power button), select Wipe Data, then Wipe All Data and confirm the action. After the process, select Reboot.
β οΈ Warning: Make sure the battery is at least 50% before reset. interrupting the data writing process can damage the boot partition and turn the phone into a "brickΒ».
There is also a less radical method, which is to reset only system settings without deleting files. It is available via Settings β About Phone β Resetting β Erase all data (some versions have the option βDo not delete filesβ, but it does not always work stably), This method helps to correct configuration errors that cause cyclical entry into power saving mode.
Hardware causes and battery wear
If the smartphone battery is a few years old, its actual capacity could have dropped significantly, in which case the power controller may misidentify the charge level by drastically discounting interest and forcibly turning on ultra-saving mode, even if the screen displays 20-30%.
You can check the battery status using a hidden menu or special applications. In the Xiaomi engineering menu (call # # #6484##) there are battery tests. Pay attention to the settings "Status" and "Health." If the status indicates "Bad" or "Replace", the software methods will not help - you need to replace the battery in the service center.
- π‘οΈ Overheating: At high temperature, the throttling processor is, and the system may include savings for cooling.
- π Controller problems: Unstable voltage from charger may cause malfunctions in software logic.
- π Cell degradation: Old lithium-polymer batteries lose their ability to hold voltage under load.
If you notice that the phone turns off or goes into deep sleep at 15-20% charge, this is a sure sign of the need to replace the battery. Using original or certified Xiaomi batteries guarantees the correct operation of energy saving algorithms.
