Cleaning Xiaomi memory: what it is and whether it should be done

Smartphone owners often notice a notification or widget on the screen that says “Clear Memory,” which raises questions among inexperienced users, a feature that is part of the proprietary shell of MIUI or the new HyperOS, and is designed to manage the RAM (RAM) of a device, which many confuse with freeing up space in a file store, but the mechanism here is fundamentally different.

When the system tells you to clear Xiaomi’s memory, it suggests you force the process of applications that run in the background to be terminated.This action frees up the CPU and RAM resources that have been reserved for quick switching between programs. Understanding how this mechanism works will help you extend battery life and avoid misconceptions about optimization.

Should we trust the system's automated recommendations or should we manually control the running processes? The answer to this question is not as clear as it may seem at first glance. Modern Android algorithms have learned to manage resources effectively, but in specific cases, user intervention is really necessary.

Difference between RAM and Storage

The first thing you need to learn to manage a device properly is to make a clear distinction between the two types of memory: RAM is a temporary storage that stores data from applications that are running right now, it only works when the power is on, and it is cleared when you reboot or turn off your smartphone.

Internal storage (ROM or Flash Memory) is where your photos, installed programs, music and system files are located. When you download a file from the Internet, it lands here. The Clear Memory feature in the standard Security app often combines management of both types, creating confusion.

If the system says that 90% of memory is occupied, it is important to understand what type of memory it is, filling the file storage makes it impossible to install new applications or take photos, overflowing RAM causes the interface to slow down and programs to crash.

How does a standard cleaner work in MIUI and HyperOS

The built-in optimization tool, available through the Security app, scans the system's state, analyzes the number of free megabytes in RAM and the amount of cache in internal storage, and pressing the cleanup button forces the background processes to end.

The cleaner’s algorithm is aggressive compared to pure Android.It aims to free up as many resources as possible, even if apps have been rolled out recently.This is a characteristic of Xiaomi’s shell, aimed at maintaining high performance in games and heavy tasks.

💡

If you see a notification "Memory is full," first check the amount of free storage space. Often it is the lack of gigabytes for files, rather than RAM, that causes problems with updating applications.

However, constant manual cleaning can have the opposite effect: the applications you use regularly (messengers, mail) when re-started after cleaning consume more CPU power, as they need to be re-initialized, a phenomenon known as the “reboot cycle”.

Impact of cleaning on productivity and battery

There is a common myth that frequent RAM cleaning speeds up a smartphone. In reality, the situation is more complicated. If your device has 4-6 GB of RAM, constant cleaning can be useful, since the system has nowhere to keep the cache. On models with 8-12 GB or more, this action is often meaningless.

So the battery, the law of conservation of energy, requires more processing power to run an application from scratch than to recover it from RAM sleep, so using the Clear Everything button often can paradoxically increase the charge consumption.

However, there are situations where cleaning is necessary:

• 📉 The smartphone began to noticeably slow down and hang in the interface.
• 🎮 You are going to run a hard game and want to give it the maximum resources.
• 🔋 One of the applications “sucked” and consumes energy in the background.
• ❌ The program stopped responding to commands and did not close.

Instructions: manual and automatic cleaning

There are several proven methods to do the cleaning on Xiaomi, Redmi and Poco devices, and the easiest way is to use a desktop widget, which is usually a pie chart showing the percentage of RAM usage.

If you don't have a widget, you can use the system menu. Press the "Menu" button (square or three bars, depending on the navigation settings) or swipe bottom-up with a delay. The list of running applications that opens often has a cleaning button (broomstick icon or cross).

Deep cleaning is also available through settings:

1. Open the Settings.
2. Go to the About Phone section.
3. Click on the Warehouse line.
4. Use built-in tools to analyze large files.

It's important to distinguish between cache cleaning and data cleaning. Cache are temporary files that can be deleted safely. Data is your logins, settings, and progression in games within a particular application.

⚠️ Warning: Do not use third-party “process killer” apps from the Play Market. They conflict with the system management of Android memory, which leads to unstable operation and rapid battery discharge.

Analysis of the space occupied in the vault

When it comes to lack of space for files, a standard cleaner may not be informative enough; for detailed analysis, it is better to use a built-in storage analyzer, which shows which categories of files occupy the most gigabytes.

Most often, messengers (Telegram, WhatsApp) that save all the photos and videos received, as well as streaming services that caching content for offline viewing, regularly checking these folders allows you to free up a significant amount of space.

The following is a table of data types and recommendations for their deletion:

Special attention should be paid to the DCIM folder, where your photos and videos are stored. Often there are unsuccessful frames or duplicates that only take up space. Regularly transferring media files to your computer or to the cloud (Google Photos, Yandex.Disk) is the best prevention of overflow.

💡

The storage system analyzer in MIUI shows the exact size of the folders, which allows you to quickly find the “eaters” of the place that are not visible in a conventional conductor.

Advanced Memory Management Methods

There are deeper controls for advanced users, and you can set the backend limit in the Developer menu, but you only need to do that if you know exactly what services you don't need.

Memory Extension, available on new models, allows you to use part of the internal storage as virtual RAM, which helps keep more applications open, but can slightly reduce the speed of the drive.

If the smartphone is slow even after cleaning, try resetting the network settings or clearing the system partition cache through Recovery Mode. These are more radical measures that require caution.

⚠️ Attention: Memory Extension uses the internal storage cycle life intensively. On older devices with worn flash memory, this can reduce the life of a smartphone.

Using ADB (Android Debug Bridge) commands allows you to remove system “garbage” and bloatware, but this requires a connection to a PC.
