Xiaomi Redmi 9 with non-removable battery: what to do if the phone does not respond to the buttons

You picked up your Xiaomi Redmi 9 and the screen froze in one image, the buttons don't work, and even the long Power hold doesn't work? This is familiar to many non-removable smartphone owners, where the classic way to "take out the battery" is not available. In this article, we'll discuss why Redmi 9 is frozen, how to restart it without risking data damage, and what to do if standard methods do not work.

The main problem with non-removable batteries is that they can't physically turn off power, which makes it difficult to diagnose, because the cause of the freeze can be either a software failure (such as an application conflict or a firmware error) or a hardware malfunction (overheating, damage to the battery or motherboard), and we'll look at both scenarios, from the safest ways to radical measures that will help bring the phone back to life.

Important: if Redmi 9 is stuck after a fall, moisture or severe overheating, immediately go to the section about hardware malfunctions - there is no longer a service center. In all other cases, try the solutions from this manual.

Why Xiaomi Redmi is Hanging Up 9: top-up-5 cause

Before you start rebooting, you should understand what triggered the freeze, which will help you avoid repeated failures in the future.

• 🔄 Application conflict: one or more apps have been suspended and blocked, often to blame for games, social networks (especially Facebook or TikTok) or memory optimizers.

If it freezes once, it's probably the software that's to blame. If the phone brakes and freezes regularly, the problem can go deeper, from battery wear to memory chip failure, and only diagnostics in the service will help.

Method 1: Software reboot (if the screen reacts)

If the phone isn’t fully locked (for example, the screen responds to touches but apps don’t open), try rebooting it via the menu:

1. Hold the Power button for 10-15 seconds until the off menu appears.
2. Slip on the Restart option and confirm the action.

If the menu doesn’t appear but the screen responds to gestures, try an alternative way:

1. Open the notification panel with a swipe from top to bottom.
2. Click on the icon. ⚙️ Settings → The phone. → Reboot.

This method will only work if the system is partially functioning, so if the screen is completely black or frozen in one image, move on to the next section.

💡

If your phone is stuck on the lock screen, try unlocking it through your Mi Account on another device – sometimes it helps to defrost the system.

Method 2: Forced reboot (if the phone doesn't respond)

When Redmi 9 is completely locked and does not respond to pressing, a hardware reset is required.

1. Hold the Power + Volume Up button at the same time for at least 20 seconds.
2. Release the buttons when the Xiaomi logo or vibration appears on the screen.

This combination simulates battery extraction and resets the power to the processor, so if the phone freezes again after the restart, the problem could be the firmware or the hardware.

⚠️ Note: Do not use this combination more than 1 time per day.Frequent forced reboots can cause file system damage and data loss.

If after a forced reboot the phone does not turn on or hovers on the MI logo, this is a sign:

• 🔄 Damaged firmware (requires flashing through Fastboot).
• 💾 Loader errors (reinstallation needed) MIUI via Mi Flash Tool).
• 🔋 Critical battery discharge (wait 30 minutes on charge).

Method 3: Safe loading (for diagnostics)

If the phone turns on but freezes, try running it in Safe Mode, which will turn off all third-party apps, and you can determine if the software is to blame:

1. Turn off the phone (if it doesn’t respond, use the forced reboot from the previous section).
2. Hold the Power button until the Xiaomi logo appears.
3. Once the logo appears, press and hold the Volume Down button until the download is complete.

In Safe Mode, the bottom of the screen will say Safe Mode. If the phone is stable, the problem is in one of the installed applications. Uninstall recently installed programs or reset to factory settings.

Delete suspicious applications | Check free memory | Disable autoload programs |Reset settings (if it didn't help)

Method 4: Battery problems - when the battery is to blame

The non-removable battery in the Redmi 9 is the weak spot of the model. Over time, the battery swells, loses capacity or refuses to hold charge.

• 🔋 It freezes when you connect the charging;
• 📉 Turns off 20 to 30% of the charge;
• 🔥 Heated in the battery area;

The problem is probably the battery.

If the battery is swollen, do not try to repair it yourself - it is dangerous! Contact the Xiaomi service center or an authorized workshop. The average cost of replacing the battery for the Redmi 9 is 1,500-2,500 rubles (2026).

⚠️ Warning: If the phone body is deformed (the screen or back cover is arched), it is a sign of battery bloating!

Method 5: Hardware malfunctions - when a workshop is needed

If none of these methods worked and the phone still doesn’t respond, the problem may be:

• 🔌 Damaged motherboard (after falling or getting moisture);
• 🖥️ Faulty memory chip (phone turned on, but hangs on logo);
• 📶 Broken display plume (screen does not respond to touch).

In these cases, self-repair is not possible - professional diagnosis is required, here are the signs for which you should contact the service:

• 💧 The phone fell into the water or was exposed to high humidity;
• 💥 There are cracks or dents on the body;
• 🔥 The phone is overheating even in plain;
• 🔌 Not charged or turned on after charging.

Average cost of repair Redmi 9 in the service (for 2026):

• Replacement of the display is 3000-5000 rubles.
• Mainboard repair – 2 000-10 000 rubles (depending on damages)
• Replacement of the plume - 1000-2 500 rubles.

How to Prevent Frosting in the Future

To prevent Redmi 9 from hanging up again, follow these guidelines:

• 📱 Update the firmware through Settings → The phone. → System updates. Updated versions. MIUI Correcting Stability Mistakes.
• 🧹 Clean the cache once a month: Settings → Memory. → Cleanup.
• 🔋 Avoid full discharge – charge your phone at 15-20% charge.
• 🚫 Do not install memory optimizers – they often conflict with the system.
• 🔥 Watch the temperature: if the case is hot, let the phone cool down.

If the phone is already “gone” (it took 2+ years from buying), consider replacing the battery or resetting to factory settings (via Settings → Additional → Recovery and Reset).

💡

Regular maintenance (cleaning cache, updates, charge control) extends the life of the smartphone by 30-50%.
