How to Clean Cache on Xiaomi Mi 8 Lite: The Complete Guide

Owners of the popular Xiaomi Mi 8 Lite often experience a slowdown after a year or two of active use, a natural process of accumulating temporary files that the system and applications create to quickly load content, and over time, this cache grows to gigabytes, occupying precious space in internal memory and causing the interface to slow down.

Clearing temporary files is a safe and effective procedure that doesn’t delete your personal data, such as photos or contacts. In this article, we’ll look at all the memory freeing methods available, from built-in MIUI tools to advanced actions through the engineering menu.

Proper file system maintenance allows you to extend the life of your smartphone and avoid sudden freezes. Below are proven algorithms of actions that will help you return the Mi 8 Lite to its former sharpness.

Use of the built-in "Security" application

The easiest and most affordable way to remove system debris is to use a standard tool from the firmware developers. The MIUI shell already has a powerful optimizer that can find and delete unnecessary files. To start the procedure, you need to find an icon on your desktop called "Security" (green shield) and start the scan.

Once the analysis is complete, the system will suggest that you delete the files you found, but don't blindly trust the automation, as sometimes useful logs or thumbnails that you plan to use in the near future can fall into the category of "junk" and a deeper cleanup is available through the "Cleanup" menu, where you can choose in detail the types of data you delete.

It is important to note that the cache of applications in this mode is deleted selectively. Some programs, such as messengers or browsers, can save their temporary files in secure directories, which a standard scanner does not always have access without root rights.

• 📱 Click on the “Security” icon in the Tools folder».
• 🧹 Select the “Cleanup” option for manual file management.
• ✅ Check the boxes "Cash" and "Advertising files».
• 🗑️ Click the “Clear Selected” button at the bottom of the screen.

💡

Standard cleaning is safe, but only removes the surface layer of temporary files without affecting deep system caches.

Removing the cache of individual applications through settings

If a particular program, such as Telegram or YouTube, takes up too much space, it is more effective to clear its cache individually, which allows you to free up a significant amount of memory without affecting the data of other services. → Annexes → All applications.

In the list, find the app you want and tap it. In the menu that opens, select Memory. Here you'll see two buttons: Clear and Clear Everything. The first one deletes only temporary files, the second one resets the app to the state immediately after installation, removing logins and settings.

⚠️ Note: Using the "Clear Everything" button will result in logging out of your account in the app. You will have to enter your login and password again.

This method is especially relevant for the Xiaomi Mi 8 Lite, which has a limited amount of internal memory in the basic versions. Regular check of “heavy” applications helps to keep the system in good shape.

• 🔍 Go to the "Applications" section in the system settings.
• 📂 Choose the app that takes up the most space.
• 🧽 Click on “Clean” (not to be confused with “Clean it all»).

Cache reset via Recovery Mode

A more radical but highly effective method is to clean the Cache Partition through the Recovery Mode, which removes any temporary system files that have accumulated since firmware updates or Android crashes, and doesn’t affect user data (photos, contacts).

To enter Recovery mode on the Mi 8 Lite, you need to turn off the 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 button, continuing to keep the volume.

Volume Up + Nutrition → Logo Mi → Let go of food

In the menu, you can navigate with volume buttons and select with power buttons. Find Wipe Data, then select Wipe Cache. Confirm action. Once you're done, select Reboot to reboot.

• 📴 Turn the device off completely.
• 🔊 Hold the volume up. + The button Include.
• 🔘 Use volume buttons to navigate the menu.
• ✅ Select Wipe Cache and confirm with the power button.

Cleaning DNS cache to speed up internet

Sometimes problems with page loading speed are not related to the memory of the phone, but to outdated entries in the phone. DNS This is a domain name match table and IP-On the Xiaomi Mi 8 Lite, it can be cleaned through a hidden engineering menu.

Open the Phone app and dial ##4636#. Immediately after entering the last star, the Check menu will open. Select Wi-Fi Information.

At the bottom of the screen, find the Flush DNS button, and clicking on it will instantly clear the matchsheet, which can help if sites open with an error or load an old version of the page.

| :--- | :--- | :--- |

| DNS Cache | Temporary address records | Accelerates re-access to sites |

| Flush DNS | Clearing the table | Solves problems with access to sites |

| Location Test | GPS | Not affecting memory, testing module |

| Wi-Fi Status | Connection Status | Shows current speed and IP |

⚠️ Note: Menu ##4636## is engineering. Don't change the radio settings (Radio Info) if you don't understand their purpose, it can lead to the loss of the network.

Automation of cleaning with scripts

For advanced users who don't want to manually monitor the amount of garbage, there is the possibility of automation. On MIUI you can use third-party utilities or built-in scripts if the phone has root rights. However, even without superuser rights, you can set up regular cleaning of the browser cache.

In Chrome or the standard MI Browser, you can set automatic deletion of history and cache when you leave the application, which prevents the growth of cookies and temporary images.

Also worth paying attention to the "Extended Cleanup" feature in the Security app, which can be activated in the settings of the application itself, which allows you to delete the remnants of remote applications and empty folders.
