How to make sure that applications do not close on Xiaomi Redmi Note 8T: the complete guide

Xiaomi Redmi Note 8T is a popular smartphone with a productive Snapdragon 665 chipset and 4 GB of RAM, but many users face a problem: applications spontaneously close in the background. This is especially annoying in messengers (Telegram, WhatsApp), navigators (Yandex.Maps, Google Maps) or while listening to music. The reason lies in the aggressive optimization of MIUI, which saves battery power at the cost of convenience.

In this article, we will discuss 5 working ways to disable automatic closing of applications on the Redmi Note 8T — from standard settings to hidden ADB functions. All methods are tested on MIUI 12-14 and do not require root rights. Importantly, some solutions can increase battery consumption, but this is a fee for stable operation of background processes.

Why is Xiaomi closing apps in the background?

Xiaomi has integrated Memory Optimization into MIUI, which works on three principles:

• 🔋 Battery savings: the system pauses inactive apps to cut power consumption.This is critical for the Redmi Note 8T 4,000mAh battery.
• 🧠 Liberation. RAM: 4 GB of RAM is quickly clogged, and MIUI It removes unnecessary processes from memory. The algorithm often fails to close messengers or music players.
• 🤖 Auto-cleanup: Auto-cleanup is triggered when you lock the screen or switch between apps.

In practice, it looks like this: you listen to music on Spotify, you lock the screen — after 5 minutes, the player stops. Or you write a message in Viber, switch to the browser, and when you return the chat restarts. The culprit is com.miui.powerkeeper, which manages the background processes.

Method 1: Disabling Battery Optimization for Individual Applications

The safest method is to add the right programs to the exception list, which won’t shut down optimization entirely, but will allow the key applications to run in the background.

1. Open Settings → Applications → Application Management.
2. Select a problem app (such as Telegram).
3. Slip on battery consumption.
4. Enable the No Limits option (or No Limits on new MIUI versions).

For Android 10+ (MIUI 12 and later), the way is different:

Settings → Battery and Performance → Battery Consumption Management → Application Selection → Without Limitations

Open battery settings for the application|The “No-restrictions” regime has been chosen"|Rebooted smartphone to apply changes|The behavior of the application in the background-->

⚠️ Attention: After update MIUI You can reset your settings. Check for exceptions after each update!

Method 2: Disable the "Memory Cleanup" (RAM Boost) function

The Redmi Note 8T has a built-in RAM Boost tool that forcibly closes apps when the screen is locked.

1. Go to Settings → Special Opportunities → System Acceleration.
2. Disable Memory Cleanup Slider when Locked (or Deep Clean in Global versions of MIUI).
3. In some firmware, the option is hidden: use the search by settings (magnifying icon) and enter the memory cleanup request.

On MIUI 14 for the Redmi Note 8T, the feature may be called “Smart Cleanup” and can be found in the “Battery → Battery Settings → Additional” section.

💡

If you don't have the option to "Memory Cleanup", try changing the firmware region to "India" via Settings → Additional → Region. This will reveal hidden settings.

Method 3: Using a Developer (ADB-team)

For advanced users, there's a method with ADB that completely disables optimization for the selected applications, and you'll need a computer and a developer mode on.

Step 1: Activate the Developer Mode:

1. Go to Settings. → The phone.
2. Tap 7 times on the MIUI version.
3. Return to Settings → Additional → For developers and enable USB debugging.

Step 2. Connect to the PC and execute the commands:

adb shell dumpsys deviceidle whitelist +com.example.app


adb shell cmd deviceidle force-idle

Replace com.example.app with an app package (e.g. org.telegram.messenger for Telegram) and find out through the Play Market or App Inspector app.

⚠️ Attention: Misuse of the right ADB Do not add more than 5 applications to the whitelist, it will lead to overheating and rapid discharge.

Method 4: Set up Auto-Run Applications

MIUI blocks auto-start background processes to save resources, so that applications remain active:

1. Open Settings → Applications → Application Management.
2. Select the application you want (for example, Viber).
3. Slip on Autostart and turn on the slider.
4. Go back and activate Show notifications (this will prevent closure due to lack of activity).

Android 11+ also requires:

Settings → Notifications → Additional → Notification permissions → [Application] → Enable all types

💡

Auto-start + notifications = guarantee that the application will not close, but this will increase battery consumption by 5-15%!

Method 5: Reset battery settings (extreme case)

If previous methods didn't work, reset the battery settings to factory settings, which will remove all user restrictions and return MIUI default settings:

1. Go to Settings → Battery and Performance.
2. Tap on three points (⋮) top-right.
3. Select Reset Battery Settings.
4. Confirm the action and restart the smartphone.

After discharge:

• 🔄 Configure the application exceptions again (see Method 1).
• 📱 Turn it off. RAM Boost (see Method 2).
• ⚡ Check your work for 24 hours – sometimes the effect does not appear immediately.

⚠️ Warning: Reset will remove battery consumption statistics and customized energy saving settings. Don't confuse it with a full phone reset (Hard Reset)!

Additional Tips for Stable Work

To minimize the closure of applications without sacrificing the battery:

• 🔋 Use the Performance Mode (Settings) → Battery → Battery mode → Performance. That'll turn off some optimizations, but it'll increase the cost by 20-30%.
• 🗑️ Clean the cache regularly through Settings → Warehouse → Clear the cache. Clogged cache causes memory management to fail.
• 📱 Update the firmware. MIUI 14 improved logic of working with background processes for Redmi Note 8T.

Alternatively, if the problem is only with messengers, install their Lite versions (like Telegram X or Messenger Lite) that consume less resources and are less likely to close.

💡

The optimal balance is to turn on No Limits for 2-3 critical applications and keep RAM Boost active, which will save the battery and prevent the closure of important processes.
