How to clean RAM on the phone Xiaomi Redmi Note 8 T

Modern mobile operating systems, especially add-ons like MIUI, consume significant resources even in the background. The owner of the Xiaomi Redmi Note 8 T smartphone often faces a situation where the device begins to slow down, applications open longer than usual or suddenly close. This is a direct consequence of overflow of RAM, which is a critical resource for system performance. Unlike built-in storage, RAM is not designed for long-term storage of files, but its lack directly affects the smoothness of the interface.

The cleaning process does not always require the installation of third-party software, since Android tools and MIUI shells allow you to effectively manage running processes. However, many users are limited to just closing tabs, unaware of deeper optimization methods. Proper resource management allows you to extend the life cycle of the device and avoid intrusive lags in games or social networks. Below we will discuss proven ways to release RAM that are safe for your gadget.

It is worth noting that completely zeroing the free memory index is not always a good thing, since the system caches frequently used data to speed up work. However, when less than 500 MB of 4 GB (or 6 GB in the Pro version) are free, the stability of the operating system is disrupted. It is important to learn to distinguish the normal operation of background services from the “eaters” of resources that can and should be turned off.

Standard Cleaning Methods Through Multitasking Menu

The most obvious and affordable way to free up resources is to use the built-in Task Manager. On Xiaomi Redmi Note 8 T smartphones, it is called by swiping from the bottom up (when navigating gestures) or pressing the Menu button (when using classic navigation), at the bottom of the screen, an “X” or “Clean” button will appear, which forcibly terminates the processes of applications that are engaged in active RAM.

However, simply closing applications is not always effective, as many of Google’s services and MIUI system services automatically restart. For a deeper cleanup, you can use the built-in Security app. It analyzes the current state of the system and suggests (one-tap) cleaning. Click on the Cleanup button in the Acceleration section to allow the system to select the processes to complete.

💡

Don’t try to keep your memory 100% free – this makes the processor turn to slow flash storage more often, which can even slow down.

The effectiveness of this method depends on the number of programs installed. If you use heavy video editing applications or navigators, they can take up hundreds of megabytes even when folded. Regular cleaning through the multitasking menu helps to reset accumulated caching errors, but does not solve the problem of “memory leakage” in the code of the applications themselves.

Managing Autoboot and Background Processes

One of the main reasons for the lack of RAM on the Xiaomi Redmi Note 8 T is the excessive number of programs running with the system. The MIUI shell allows you to flexibly adjust this setting, preventing unnecessary applications from working in the background. This not only saves RAM, but also significantly extends battery life.

To set up, go to Settings → Apps → Autoboot. Here you will see a list of programs that start immediately after you turn on your phone. Leave only messengers (if notifications are important to you) and system services on. Social networks, games and utilities can be safely turned off - they will only start when you open them yourself.

⚠️ Note: Do not disable system services with names that contain «MIUI», «System, Google Play Services or Xiaomi, otherwise the phone may not work properly or stop accepting notifications.

Additionally, you should check application permissions. Many programs require permission to work in the background, which allows them to be constantly hanging in memory. Go to Settings → Applications → Application Management, select a suspicious application, and find “Start” or “Other permissions.” Disabling background activity for heavy applications like marketplaces or news aggregators can free up to 200-300 MB of RAM.

Using Developer Mode to Limit Memory

For advanced users who want to manually control resource allocation, there is a Developer Menu that has a feature that artificially limits the number of background processes, a radical method that forces the system to aggressively unload applications from RAM as soon as you switch to another task.

To activate this mode, go to Settings → About Phone and quickly click 7 times on “MIUI Version.” After you see “You became a developer”, go back to the main settings menu, open Additional → For Developers. Find the “Apps” section and select “Background Process Limit”.

The default is “No Limits”; you can change it to “No More than 2 Processes” or “No More than 4 Processes” and this will force Android to remember only the active application and one or two previous ones, but be prepared for the fact that the music in the player may be interrupted, and the pages in the browser will start loading again every time you return.

💡

Using a background limit is the most effective way to guarantee free memory for games, but it impairs multitasking.

Cleaning cache and deleting temporary files

Although the cache is technically stored in internal memory, processing and indexing it often puts a strain on RAM, especially if the file system is fragmented or crowded. The Xiaomi Redmi Note 8 T accumulates gigabytes of garbage from browsers, social networks and instant messengers over time. Cleaning up this data not only frees up space, but also reduces the load on the memory manager.

Use the built-in “Security” app» -> «Cleanup. It will find temporary files, deleted app residues and advertising debris. For a deeper cleanup, you can use the Deep Cleanup feature on the same menu. It's also useful to manually clear the cache of heavy applications: Settings → Annexes → Application management → [Select an application] → Memory. → Clear the cache.

Pay special attention to multimedia messengers like Telegram and WhatsApp, which store thousands of thumbnails and videos in cache. Inside the settings of these applications, there is a separate section “Data and Memory” → “Memory Use” where you can safely delete the cache without losing correspondence, which can free up from 500 MB to several gigabytes, which indirectly improves the responsiveness of the system.

Memory consumption analysis through engineering menu

Android has a hidden test menu that allows you to see the actual resource consumption by each process, even the system. On Xiaomi Redmi Note 8 T, you can get there through dialing. Enter the code ##4636#. If the menu does not open, activate it via ADB with the command adb shell am start -n com.android.settings/.TestingSettings.

In the menu that opens, select "Usage statistics" where you can sort through memory usage processes. You may find that some rarely used application consumes 400MB of RAM in the background. Once you see the "culprit," you can decide whether to delete or limit it. It's a more accurate tool than a standard task manager.

There's also a Running services feature on the developer menu that shows which services are active right now and how much memory they take up. If you see a service of an unknown application that takes up a lot of resources, you can stop it right from this menu (Stop button), but this action is temporary - the service will start again the next time the application starts.

⚠️ Note: Do not change settings in the engineering menu that you do not know the value of.Resetting network settings or changing the modes of the radio module can lead to loss of communication or unstable operation of the phone.

Radical measures: resetting and reflashing

If the software methods don’t help and the phone continues to brake even after cleaning, there may be critical errors or malware in the system. In such cases, a complete factory reset helps. Before that, be sure to back up the data to the Google cloud or to your computer, as all the information will be deleted.

Reset is done via Settings → Phone → Settings Reset → Erase all data. After this procedure, the Xiaomi Redmi Note 8 T will return to the “out of the box” state and RAM will work as efficiently as possible. If this does not help, the problem may be hardware (degradation of memory chips) or require flashing through the Mi Flash Tool with full partition cleaning.

Sometimes it helps to install custom firmware (for example, LineageOS or Pixel Experience), which are devoid of heavy add-ons MIUI. On older models such as the Note 8 T, pure Android can run noticeably faster and consume less RAM. However, this requires unlocking the bootloader, which cancels the warranty and carries risks for inexperienced users.
