How to keep your phone from turning off: a complete guide for Xiaomi

When Xiaomi’s smartphone suddenly goes out, it can be taken by surprise at the most inopportune moment. Often users are faced with MIUI aggressively controlling background processes, forcibly shutting down applications or disabling functions to save energy. Understanding the logic of the system is the first step to solving the problem. Device owners often look for a way to keep the phone from turning off, forgetting that there may be both software limitations and hardware malfunctions behind it.

It should be noted that spontaneous shutdown is a protective mechanism that in some cases prevents damage to components. However, if the gadget is working, and the problem lies in the settings, the situation is easy to fix. In this article, we will discuss everything from trivial lack of charge to complex software conflicts. You do not need to be an IT expert to configure the device correctly.

It's important to understand that different models, whether it's a budget Redmi Note or a flagship Xiaomi Mi, can have nuances in the settings menu. The interface of the MIUI shell or HyperOS changes periodically, but the basic principles remain unchanged. We'll look at universal methods that will suit most current firmware versions. Get ready for a detailed dive into the settings of your device.

Diagnostics of causes of sudden disconnection

Before you change the settings, you need to understand the nature of the problem, and most often, the phone turns off because of a critical battery discharge or a power surge, if the battery is worn out, it can show 20% charge and then go to zero abruptly, in such cases, software methods will not help, you will need to replace the battery.

Another common cause is overheating of the processor. Android's protection system activates when the temperature reaches dangerous values, which often happens when using sun navigation or during heavy games. If the device's body is hot to the touch, let it cool down before continuing the diagnosis.

⚠️ Warning: If the phone only turns off when connected to the network or when calling, this may indicate a malfunction of the power controller or plume.

Software failures also play a role: Conflicting applications or errors after a system update can cause cyclical reboots; analyze what actions the problem started after; if the phone stopped working normally immediately after installing a new program, the cause is likely to be due to it.

Setup auto-start and application background

The most common reason messengers or navigators stop working is aggressive energy saving, because the system considers an unused application as an unnecessary resource user and kills its process, so that the phone does not turn off programs that are important to you, you need to set up auto-start.

Go to Settings → Applications → Autorun. Here you will see a list of all installed programs, find the desired application (for example, Telegram or Yandex.Navigator) and activate the switch, which will allow the program to run with the system and remain in memory.

Next, you need to set the background limits. Go to Settings → Battery and Performance. In this menu, find the button "Application Management" or "Application Battery Consumption." Select the software you're interested in and set the "No Limits" mode.

• 📱 Open the settings and find the "Applications" item".
• 🔋 Go to the Battery section and select Energy Saving".
• 🚀 Find the program in the list and select "No restrictions".
• ✅ Check that the Auto Start switch is activated.

After that, the system will stop forcing the processes of the chosen application, which is especially important for activity trackers, smartwatches and navigators, which must be running all the time, but remember that this can increase overall battery consumption.

Using Developer Mode and Sleep Blocking

To fine-tune it, you can use the hidden developer menu, and you can find the settings that affect how the system works, and you can activate this mode by clicking on the build number in the About section several times, and when the notification appears, the menu will be available.

In the developer menu, we're interested in the "Stay awake" option, which is that if you activate this feature, the display will burn continuously while the phone is connected to the charger, which is useful if you're using your smartphone as a navigator in your car or as a smart home control panel.

This command, via USB debugging, compulsorily activates the constant power mode when connected, but be careful: prolonged burning of the screen to maximum brightness can lead to a matrix burnout or overheating. Use this feature only when necessary.

Working with an alarm clock and task scheduler

Many users want the phone to turn on by itself on the alarm clock. In Xiaomi, this feature is built in, but requires the right setup. In the Watch app, there is a special switch "Switch on the alarm clock." If it is active, the phone can start even from the off state at the appointed time.

This requires that the alarm be set in advance and the phone itself be switched off software, not because of battery drain. If the battery is zero, the function will not work, as it requires a minimum charge to turn on. Make sure that this option is activated in the settings of the watch application itself.

There's also a feature called "Switch-on and off scheduler." It's on the Settings path → Battery and Performance path → Planner. Here you can set the exact time to automatically start and shut down the device, and it's a great way to save battery at night or during business hours.

Solving overheating and battery problems

If the phone turns off due to overheating, no software settings will help until the physical cause is eliminated. Lithium polymer batteries are sensitive to temperatures above 45 degrees. In summer, try not to leave the gadget in the sun, especially on the torpedo of the car.

Check the status of the charger. Using cheap power supplies without certification can lead to power surges that the system perceives as a threat and emergency shuts down. Xiaomi's original charging has protection and transmits the right currents.

• 🌡️ Remove the case while charging or playing.
• 🔌 Use only certified cables and blocks.
• 📉 Close heavy applications when heating the case.
• 🧊 Do not put your phone on soft surfaces when charging.

⚠️ Warning: A bloated battery is a direct fire safety threat.If the back cover of the phone is swollen or the screen is wavering, stop using immediately and replace the battery.

Resetting and system update

If the software failures are system-specific, resetting will help. Before you do this, make sure to back up your data via Mi Cloud or Google Account. Go to Settings → About Phone → Reset and select “Erase all data”.

Often, the problem is to update the firmware to the latest version. Developers are constantly releasing patches that fix power management errors. Check for updates in the About menu. If automatic updates do not come, you can download the firmware manually from the official website.

💡

Before resetting, record or photograph important network settings and accounts to quickly restore access to the services.

Once reset, the phone will return to factory status, which will eliminate the impact of third-party apps and junk files, if the problem persisted because of a software conflict, it should disappear, and if the phone continues to turn off on a clean system, it's the hardware.

💡

Hard Reset eliminates 90% of software causes of spontaneous shutdown, but takes time to restore settings.
