How to Clean Cache on Xiaomi Redmi 8: The Complete Guide

Xiaomi Redmi 8 smartphones running MIUI shells are becoming more important for internal memory over time. The accumulation of temporary files, residual data from remote programs and system debris can significantly slow down the device. Users often notice that the phone starts to open applications longer or spontaneously close them, which is directly related to overflow of dedicated memory buffers.

Cache cleaning is not just about removing extra gigabytes, it's an important technical prevention procedure. Unlike a complete reset, it's safe for your personal data, photos and contacts, but it's important to understand the difference between app cache and data so you don't accidentally delete saved passwords or game progress.

In this article, we will take a closer look at all available methods for optimizing storage on your device, learn how to use the built-in MIUI tools, where to look for hidden folders, and what actions will help return the smartphone to its previous speed without installing third-party software.

What is cache and why should it be cleaned on Redmi 8?

Cache is a memory area designed to store temporary files that speed up the launch of frequently used programs. When you open a social network or browser, Android stores logos, thumbnails of images and interface elements on the disk, which allows the system not to download them again from the Internet or the main memory of the processor at each next start.

But there's a downside to this mechanism, and over time, these temporary storages can grow to a few gigabytes, especially in multimedia applications and browsers, and if the cache gets corrupted or takes up too much space, it leads to operating system conflicts and errors.

⚠️ Attention: Regular cache cleaning is necessary if you notice that the phone is heating without active load or the battery is discharged faster than usual.

It's important not to confuse cache cleaning with data deletion. In the first case, we only remove temporary debris, in the second case, we erase account settings, game saves and app personalization. For Redmi 8, with its limited internal storage in the basic versions, cache size control is critical.

💡

Set a rule: conduct a deep cleaning of the messenger cache every two weeks, since they accumulate the most media debris.

Use of the built-in Security application

The easiest and safest way to free up space on the Xiaomi Redmi 8 is to use a regular developer tool. The MIUI shell has a powerful built-in optimization module that scans the system for unnecessary files.

To get started, look for an icon on your desktop called Security and run it. The app automatically performs a primary check and shows your current memory status. Click Clean to start the analysis process. The system will prompt you to delete temporary files, APK installer packages, and junk.

• 📱 Click on the Security app icon on the home screen.
• 🔍 Wait for the automatic scanning of the system to be completed.
• 🗑️ Select the category "Junk" and click the cleaning button.
• ✅ Confirm the removal of the proposed files, making sure that there is no important.

Once the procedure is complete, the system will show a report on how many megabytes or gigabytes were released. Often users are surprised to find that simply running a standard utility frees up to 1-2 GB of space, especially before installing major upgrades or new heavy games.

Manually cleaning the cache of specific applications

Sometimes global cleanup doesn’t solve a problem with a particular application that doesn’t work properly, and it requires a spot intervention in Android settings, which allows you to delete temporary files from only one program without affecting the rest, which is especially useful for “heavy” applications like Telegram, Instagram or YouTube.

Go to the settings menu of your Redmi 8. Find the Apps section and select All Apps. You will see the full list of installed software. Find the problem app and click on it. From the menu that opens, select Memory or Storage.

So here you'll see two buttons: Clear cache and Clear everything. We're interested in the first option. You click on it will instantly delete temporary files. If you click Clear Everything, the app will return to its state immediately after installation, and you'll have to re-enter your logins and passwords.

It is worth noting that some system applications may not have a cache clearing button if they are critical to the operating system, in which case the system regulates their size. Do not try to delete system process data if you are not sure of its purpose, as this can lead to unstable operation of the MIUI interface.

Cleaning the cache through the Recovery menu

There is a deeper level of cleanup available through Recovery mode, which allows you to clean the Wipe Cache Partition, which stores temporary system updates and kernel work files, which is useful if the phone freezes after a firmware update or is extremely slow.

To enter this mode, you need to turn off the Xiaomi Redmi 8 smartphone completely. Then press the volume button and the power button at the same time. Hold them until the Mi logo appears, then release the power, continuing to keep the volume. When the Recovery menu appears, use the volume buttons for navigation and the power button for selection.

1. Turn off the device


2.Clasp Volume Up + Nutrition




3. Select Wipe Cache Partition




4. Confirm action




5.Select Reboot

⚠️ Warning: Be very careful on the Recovery menu. Don't confuse the Wipe Cache Partition with Wipe Data or Wipe All Data. Selecting the Data item will result in all your personal files being deleted and back to factory settings.

Once you have selected a cleaning point, the system will warn you of the consequences. Confirm the action. The process takes only a few seconds. Once complete, select Reboot to restart the phone. The first run after this procedure may take longer than usual, as the system needs to recreate temporary files.

Storage analysis and folder work

For advanced users of Redmi 8, manual file system analysis is available. Standard MIUI Explorer allows you to see which folders take up the most space. Often users forget about downloaded files in messengers or old updates that lie dead weight.

Open the Explorer app and go to the Analyzer section, where you visualize memory. Notice DCIM (photo and video), Download (download) and social media folders. Inside instant messenger folders like WhatsApp or Viber, there are often thousands of images viewed that are duplicated in cache.

Using the file manager, you can manually find and delete files with the.tmp extension or folder called temp. However, be careful with folders that have the names of the installed applications. Deleting the contents of such a folder can lead to loss of settings or offline maps, if it is a navigator.

💡

Regular manual disassembly of the Downloads folder frees up more useful space than any automatic cleaning, as it often contains forgotten installers and documents.

Frequent errors in memory cleaning

Many Xiaomi users make the typical mistakes of trying to speed up a smartphone. Often installing cleaners from the Play Market, which consume resources and show ads, built-in MIUI tools work more efficiently and safer, because they have access to system partitions that are closed to third-party software.

Another common mistake is that you have to force the process to stop all the background applications, so users try to close all the applications through the task menu, and the Android system is designed to manage the memory itself, and the artificial closure of the applications causes the processor to waste more energy restarting them, which leads to battery drain.

• 🚫 Do not install dubious antiviruses and low-rated cliners.
• 🚫 Do not delete system files whose purpose you do not know.
• 🚫 Do not use the memory speed feature that promises 100% speed.

It is also worth mentioning the risks of using ADB-Clearing the cache through the computer is possible, but one error in the syntax of the command can lead to the removal of important partitions. For the average Redmi 8 user, this is not necessary unless the phone is in a bootloop state).
